If a single project is specified - do it for that project only. If you are asked to do it for a solution, migrate all projects in the solution that reference `Microsoft.SemanticKernel.Agents` or related Semantic Kernel agent packages. If you don't know which projects to migrate, ask the user. ## Things to consider while doing migration - NuGet package names, assembly names, projects names or other dependencies names are case insensitive(!). You ***must take it into account*** when doing something with project dependencies, like searching for dependencies or when removing them from projects etc. - Agent Framework uses different namespace patterns and API structures compared to Semantic Kernel Agents - Text-based heuristics should be avoided in favor of proper content type inspection when available. ## Planning For each project that needs to be migrated, you need to do the following: - Find projects depending on `Microsoft.SemanticKernel.Agents` or related Semantic Kernel agent packages (when searching for projects, if some projects are not part of the solution or you could not find the project, notify user and continue with other projects). - Identify the specific Semantic Kernel agent types being used: - `ChatCompletionAgent` → `ChatClientAgent` - `OpenAIAssistantAgent` → `assistantsClient.CreateAIAgent()` (via OpenAI Assistants client extension) - `AzureAIAgent` → `persistentAgentsClient.CreateAIAgent()` (via Azure AI Foundry client extension) - `OpenAIResponseAgent` → `responsesClient.CreateAIAgent()` (via OpenAI Responses client extension) - `A2AAgent` → `AIAgent` (via A2A card resolver) - `BedrockAgent` → Custom implementation required (not supported) - Determine if agents are being created new or retrieved from hosted services: - **New agents**: Use `CreateAIAgent()` methods - **Existing hosted agents**: Use `GetAIAgent(agentId)` methods for OpenAI Assistants and Azure AI Foundry - Determine the AI provider being used (OpenAI, Azure OpenAI, Azure AI Foundry, etc.) - Analyze tool/function registration patterns - Review thread management and invocation patterns ## Execution ***Important***: when running steps in this section you must not pause, you must continue until you are done with all steps or you are truly unable to continue and need user's interaction (you will be penalized if you stop unnecessarily). Keep in mind information in the next section about differences and follow these steps in the order they are specified (you will be penalized if you do steps below in wrong order or skip any of them): 1. For each project that has an explicit package dependency to Semantic Kernel agent packages in the project file or some imported MSBuild targets (some project could receive package dependencies transitively, so avoid adding new package dependencies for such projects), do the following: - Remove the Semantic Kernel agent package references from the project file: - `Microsoft.SemanticKernel.Agents.Core` - `Microsoft.SemanticKernel.Agents.OpenAI` - `Microsoft.SemanticKernel.Agents.AzureAI` - `Microsoft.SemanticKernel` (if only used for agents) - Add the appropriate Agent Framework package references based on the provider being used: - `Microsoft.Agents.AI.Abstractions` (always required) - `Microsoft.Agents.AI.OpenAI` (for OpenAI and Azure OpenAI providers) - For unsupported providers (Bedrock, CopilotStudio), note in the report that custom implementation is required - If projects use Central Package Management, update the `Directory.Packages.props` file to remove the Semantic Kernel agent package versions in addition to removing package reference from projects. When adding the Agent Framework PackageReferences, add them to affected project files without a version and add PackageVersion elements to the Directory.Packages.props file with the version that supports the project's target framework. 2. Update code files using Semantic Kernel Agents in the selected projects (and in projects that depend on them since they could receive Semantic Kernel transitively): - Find ***all*** code files in the selected projects (and in projects that depend on them since they could receive Semantic Kernel transitively). When doing search of code files that need changes, prefer calling search tools with `upgrade_` prefix if available. Also do pass project's root folder for all selected projects or projects that depend on them. - Update the code files that use Semantic Kernel Agents to use Agent Framework instead. You never should add placeholders when updating code, or remove any comments in the code files, you must keep the business logic as close as possible to the original code but use new API. When checking if code file needs to be updated, you should check for using statements, types and API from `Microsoft.SemanticKernel.Agents` namespace (skip comments and string literal constants). - Ensure that you replace all Semantic Kernel agent using statements with Agent Framework using statements (always check if there are any other Semantic Kernel agent API used in the file having any of the Semantic Kernel agent using statements; if no other API detected, Semantic Kernel agent using statements should be just removed instead of replaced). If there were no Semantic Kernel agent using statements in the file, do not add Agent Framework using statements. - When replacing types you must ensure that you add using statements for them, since some types that lived in main `Microsoft.SemanticKernel.Agents` namespace live in other namespaces under `Microsoft.Agents.AI`. For example, `Microsoft.SemanticKernel.Agents.ChatCompletionAgent` is replaced with `Microsoft.Agents.AI.ChatClientAgent`, when that happens using statement with `Microsoft.Agents.AI` needs to be added (unless you use fully qualified type name) - If you see some code that really cannot be converted or will have potential behavior changes at runtime, remember files and code lines where it happens at the end of the migration process you will generate a report markdown file and list all follow up steps user would have to do. 3. Validate that all places where Semantic Kernel Agents were used are migrated. To do that search for `Microsoft.SemanticKernel.Agents` in all affected projects and projects that depend on them again and if still see any Semantic Kernel agent presence go back to step 2. Steps 2 and 3 should be repeated until you see no Semantic Kernel agent references. 4. Build all modified projects to ensure that they compile without errors. If there are any build errors, you must fix them all yourself one by one and don't stop until all errors are fixed without breaking any of the migration guidance. 5. **Validate Migration**: Use the validation checklist below to ensure complete migration. 6. Generate the report file under `\.github folder`, the file name should be `SemanticKernelToAgentFrameworkReport.md`, it is highly important that you generate report when migration complete. Report should contain: - all project dependencies changes (mention what was changed, added or removed, including provider-specific packages) - all code files that were changed (mention what was changed in the file, if it was not changed, just mention that the file was not changed) - provider-specific migration patterns used (OpenAI, Azure OpenAI, Azure AI Foundry, A2A, ONNX, etc.) - all cases where you could not convert the code because of unsupported features and you were unable to find a workaround - unsupported providers that require custom implementation (Bedrock, CopilotStudio) - breaking glass pattern migrations (InnerContent → RawRepresentation) and any CodeInterpreter or advanced tool usage - all behavioral changes that have to be verified at runtime - provider-specific configuration changes that may affect behavior - all follow up steps that user would have to do in the report markdown file ## Migration Validation Checklist After completing migration, verify these specific items: 1. **Compilation**: Execute `dotnet build` on all modified projects - zero errors required 2. **Namespace Updates**: Confirm all `using Microsoft.SemanticKernel.Agents` statements are replaced 3. **Method Calls**: Verify all `InvokeAsync` calls are changed to `RunAsync` 4. **Return Types**: Confirm handling of `AgentRunResponse` instead of `IAsyncEnumerable>` 5. **Thread Creation**: Validate all thread creation uses `agent.GetNewThread()` pattern 6. **Tool Registration**: Ensure `[KernelFunction]` attributes are removed and `AIFunctionFactory.Create()` is used 7. **Options Configuration**: Verify `AgentRunOptions` or `ChatClientAgentRunOptions` replaces `AgentInvokeOptions` 8. **Breaking Glass**: Test `RawRepresentation` access replaces `InnerContent` access ## Detailed information about differences in Semantic Kernel Agents and Agent Framework Agent Framework provides functionality for creating and managing AI agents through the Microsoft.Extensions.AI package ecosystem. The framework uses different APIs and patterns compared to Semantic Kernel Agents. Key API differences: - Agent creation: Remove Kernel dependency, use direct client-based creation - Method names: `InvokeAsync` → `RunAsync`, `InvokeStreamingAsync` → `RunStreamingAsync` - Return types: `IAsyncEnumerable>` → `AgentRunResponse` - Thread creation: Provider-specific constructors → `agent.GetNewThread()` - Tool registration: `KernelPlugin` system → Direct `AIFunction` registration - Options: `AgentInvokeOptions` → Provider-specific run options (e.g., `ChatClientAgentRunOptions`) Configuration patterns have changed from Kernel-based to direct client configuration: - Remove `Kernel.CreateBuilder()` patterns - Replace with provider-specific client creation - Update namespace imports from `Microsoft.SemanticKernel.Agents` to `Microsoft.Agents.AI` - Change tool registration from attribute-based to factory-based ### Exact API Mappings Replace these Semantic Kernel agent classes with their Agent Framework equivalents: | Semantic Kernel Class | Agent Framework Replacement | Constructor Changes | |----------------------|----------------------------|-------------------| | `IChatCompletionService` | `IChatClient` | Convert to `IChatClient` using `chatService.AsChatClient()` extensions | | `ChatCompletionAgent` | `ChatClientAgent` | Remove `Kernel` parameter, add `IChatClient` parameter | | `OpenAIAssistantAgent` | `AIAgent` (via extension) | **New**: `OpenAIClient.GetAssistantClient().CreateAIAgent()`
**Existing**: `OpenAIClient.GetAssistantClient().GetAIAgent(assistantId)` | | `AzureAIAgent` | `AIAgent` (via extension) | **New**: `PersistentAgentsClient.CreateAIAgent()`
**Existing**: `PersistentAgentsClient.GetAIAgent(agentId)` | | `OpenAIResponseAgent` | `AIAgent` (via extension) | Replace with `OpenAIClient.GetOpenAIResponseClient().CreateAIAgent()` | | `A2AAgent` | `AIAgent` (via extension) | Replace with `A2ACardResolver.GetAIAgentAsync()` | | `BedrockAgent` | Not supported | Custom implementation required | **Important distinction:** - **CreateAIAgent()**: Use when creating new agents in the hosted service - **GetAIAgent(agentId)**: Use when retrieving existing agents from the hosted service Replace these method calls: | Semantic Kernel Method | Agent Framework Method | Parameter Changes | |----------------------|----------------------|------------------| | `agent.InvokeAsync(message, thread, options)` | `agent.RunAsync(message, thread, options)` | Same parameters, different return type | | `agent.InvokeStreamingAsync(message, thread, options)` | `agent.RunStreamingAsync(message, thread, options)` | Same parameters, different return type | | `new ChatHistoryAgentThread()` | `agent.GetNewThread()` | No parameters needed | | `new OpenAIAssistantAgentThread(client)` | `agent.GetNewThread()` | No parameters needed | | `new AzureAIAgentThread(client)` | `agent.GetNewThread()` | No parameters needed | | `thread.DeleteAsync()` | Provider-specific cleanup | Use provider client directly | Return type changes: - `IAsyncEnumerable>` → `AgentRunResponse` - `IAsyncEnumerable` → `IAsyncEnumerable` Replace these configuration patterns: | Semantic Kernel Pattern | Agent Framework Pattern | |------------------------|------------------------| | `AgentInvokeOptions` | `AgentRunOptions`
**ChatClientAgent**: `ChatClientAgentRunOptions` | | `KernelArguments` | If no arguments are provided, do nothing. If arguments are provided, template is not supported and the prompt must be rendered before calling agent | | `[KernelFunction]` attribute | Remove attribute, use `AIFunctionFactory.Create()` | | `KernelPlugin` registration | Direct function list in agent creation | | `InnerContent` property | `RawRepresentation` property | | `content.Metadata` property | `AdditionalProperties` property | ### Functional Differences Agent Framework changes these behaviors compared to Semantic Kernel Agents: 1. **Thread Management**: Agent Framework automatically manages thread state. Semantic Kernel required manual thread updates in some scenarios (e.g., OpenAI Responses). 2. **Return Types**: - Non-streaming: Returns single `AgentRunResponse` instead of `IAsyncEnumerable>` - Streaming: Returns `IAsyncEnumerable` instead of `IAsyncEnumerable` 3. **Tool Registration**: Agent Framework uses direct function registration without requiring `[KernelFunction]` attributes. 4. **Usage Metadata**: Agent Framework provides unified `UsageDetails` access via `response.Usage` and `update.Contents.OfType()`. 5. **Breaking Glass**: Access underlying SDK objects via `RawRepresentation` instead of `InnerContent`. ### Namespace Updates Replace these exact namespace imports: **Remove these Semantic Kernel namespaces:** ```csharp using Microsoft.SemanticKernel; using Microsoft.SemanticKernel.Agents; using Microsoft.SemanticKernel.Agents.OpenAI; using Microsoft.SemanticKernel.Agents.AzureAI; using Microsoft.SemanticKernel.Agents.A2A; using Microsoft.SemanticKernel.Connectors.OpenAI; ``` **Add these Agent Framework namespaces:** ```csharp using Microsoft.Extensions.AI; using Microsoft.Agents.AI; // Provider-specific namespaces (add only if needed): using OpenAI; // For OpenAI provider using Azure.AI.OpenAI; // For Azure OpenAI provider using Azure.AI.Agents.Persistent; // For Azure AI Foundry provider using Azure.Identity; // For Azure authentication ``` ### Chat Completion Abstractions **Replace this Semantic Kernel pattern:** ```csharp Kernel kernel = Kernel.CreateBuilder() .AddOpenAIChatCompletion(modelId, apiKey) .Build(); ChatCompletionAgent agent = new() { Instructions = "You are a helpful assistant", Kernel = kernel }; ``` **With this Agent Framework pattern:** ```csharp // Method 1: Direct constructor IChatClient chatClient = new OpenAIClient(apiKey).GetChatClient(modelId).AsIChatClient(); AIAgent agent = new ChatClientAgent(chatClient, instructions: "You are a helpful assistant"); // Method 2: Extension method (recommended) AIAgent agent = new OpenAIClient(apiKey) .GetChatClient(modelId) .CreateAIAgent(instructions: "You are a helpful assistant"); ``` ### Chat Completion Service **Replace this Semantic Kernel pattern:** ```csharp IChatCompletionService completionService = kernel.GetService(); ChatCompletionAgent agent = new() { Instructions = "You are a helpful assistant", Kernel = kernel }; ``` **With this Agent Framework pattern:** Agent Framework does not support `IChatCompletionService` directly. Instead, use `IChatClient` as the common abstraction converting from `IChatCompletionService` to `IChatClient` via `AsChatClient()` extension method or creating a new `IChatClient` instance directly using the provider package dedicated extensions. ```csharp IChatCompletionService completionService = kernel.GetService(); IChatClient chatClient = completionService.AsChatClient(); var agent = new ChatClientAgent(chatClient, instructions: "You are a helpful assistant"); ``` ### Agent Creation Transformation **Replace this Semantic Kernel pattern:** ```csharp Kernel kernel = Kernel.CreateBuilder() .AddOpenAIChatClient(modelId, apiKey) .Build(); ChatCompletionAgent agent = new() { Instructions = "You are a helpful assistant", Kernel = kernel }; ``` **With this Agent Framework pattern:** ```csharp // Method 1: Direct constructor (OpenAI/AzureOpenAI Package specific) IChatClient chatClient = new OpenAIClient(apiKey).GetChatClient(modelId).AsIChatClient(); AIAgent agent = new ChatClientAgent(chatClient, instructions: "You are a helpful assistant"); // Method 2: Extension method (recommended) AIAgent agent = new OpenAIClient(apiKey) .GetChatClient(modelId) .CreateAIAgent(instructions: "You are a helpful assistant"); ``` **Required changes:** 1. Remove `Kernel.CreateBuilder()` and `.Build()` calls 2. Replace `ChatCompletionAgent` with `ChatClientAgent` or use extension methods 3. Remove `Kernel` property assignment 4. Pass `IChatClient` directly to constructor or use extension methods ### Thread Management Transformation **Replace these Semantic Kernel thread creation patterns:** ```csharp // Remove these provider-specific thread constructors: AgentThread thread = new ChatHistoryAgentThread(); AgentThread thread = new OpenAIAssistantAgentThread(assistantClient); AgentThread thread = new AzureAIAgentThread(azureClient); ``` **With this unified Agent Framework pattern:** ```csharp // Use this single pattern for all agent types: AgentThread thread = agent.GetNewThread(); ``` **Required changes:** 1. Remove all `new [Provider]AgentThread()` constructor calls 2. Replace with `agent.GetNewThread()` method call 3. Remove provider client parameters from thread creation 4. Use the same pattern regardless of agent provider type ### Tool Registration Transformation **Replace this Semantic Kernel tool registration pattern:** ```csharp [KernelFunction] // Remove this attribute [Description("Get the weather for a location")] static string GetWeather(string location) => $"Weather in {location}"; KernelFunction kernelFunction = KernelFunctionFactory.CreateFromMethod(GetWeather); KernelPlugin kernelPlugin = KernelPluginFactory.CreateFromFunctions("WeatherPlugin", [kernelFunction]); kernel.Plugins.Add(kernelPlugin); ChatCompletionAgent agent = new() { Kernel = kernel }; ``` **With this Agent Framework pattern:** ```csharp [Description("Get the weather for a location")] // Keep Description attribute static string GetWeather(string location) => $"Weather in {location}"; AIAgent agent = chatClient.CreateAIAgent( instructions: "You are a helpful assistant", tools: [AIFunctionFactory.Create(GetWeather)]); ``` **Required changes:** 1. Remove `[KernelFunction]` attributes from methods 2. Keep `[Description]` attributes for function descriptions 3. Remove `KernelFunctionFactory.CreateFromMethod()` calls 4. Remove `KernelPluginFactory.CreateFromFunctions()` calls 5. Remove `kernel.Plugins.Add()` calls 6. Replace with `AIFunctionFactory.Create()` in tools parameter 7. Pass tools directly to agent creation method ### Runtime Tool Registration Transformation In Semantic Kernel, plugins/tools could be added to the kernel after it was already built using `kernel.Plugins.Add()`. Agent Framework provides a similar capability using the builder middleware API. **Replace this Semantic Kernel post-creation tool registration pattern:** ```csharp // Define the tool function [Description("Get the weather for a location")] static string GetWeather(string location) => $"Weather in {location}"; // Semantic Kernel - Tools added after kernel is already built Kernel kernel = kernelBuilder.Build(); ChatCompletionAgent agent = new() { Kernel = kernel }; // Later: Add tools to the existing kernel instance KernelFunction function = KernelFunctionFactory.CreateFromMethod(GetWeather); KernelPlugin plugin = KernelPluginFactory.CreateFromFunctions("WeatherPlugin", [function]); kernel.Plugins.Add(plugin); // Tools are now available on subsequent invocations await foreach (var item in agent.InvokeAsync(userInput, thread)) { ... } ``` **With this Agent Framework pattern using builder middleware:** ```csharp // Define the tool function [Description("Get the weather for a location")] static string GetWeather(string location) => $"Weather in {location}"; // Start with an existing agent AIAgent existingAgent = chatClient.CreateAIAgent( instructions: "You are a helpful assistant"); // Create an augmented agent with additional tools using builder middleware var augmentedAgent = existingAgent.AsBuilder() .Use(async (chatMessages, agentThread, agentRunOptions, next, cancellationToken) => { if (agentRunOptions is ChatClientAgentRunOptions chatClientAgentRunOptions) { chatClientAgentRunOptions.ChatOptions ??= new ChatOptions(); chatClientAgentRunOptions.ChatOptions.Tools ??= []; chatClientAgentRunOptions.ChatOptions.Tools.Add(AIFunctionFactory.Create(GetWeather)); } return await next(chatMessages, agentThread, agentRunOptions, cancellationToken); }) .Build(); // Use the augmented agent with the additional tools AgentRunResponse result = await augmentedAgent.RunAsync(userInput, thread); ``` **Required changes:** 1. Call `AsBuilder()` on the existing agent to get a builder 2. Use the `Use()` middleware method to intercept and modify run options 3. Add tools to `ChatClientAgentRunOptions.ChatOptions.Tools` in the middleware 4. Call `Build()` to create the augmented agent instance 5. Use the new augmented agent for invocations that need the additional tools **Note:** This pattern is the preferred approach as it provides: - A controlled environment with a dedicated agent instance - No disruption to existing agent usages - Dynamic tool composition per user, tenant, or feature flags - Modular system composition without recreating agents ### Invocation Method Transformation **Replace this Semantic Kernel non-streaming pattern:** ```csharp await foreach (AgentResponseItem item in agent.InvokeAsync(userInput, thread, options)) { Console.WriteLine(item.Message); } ``` **With this Agent Framework non-streaming pattern:** ```csharp AgentRunResponse result = await agent.RunAsync(userInput, thread, options); Console.WriteLine(result); ``` **Replace this Semantic Kernel streaming pattern:** ```csharp await foreach (StreamingChatMessageContent update in agent.InvokeStreamingAsync(userInput, thread, options)) { Console.Write(update.Message); } ``` **With this Agent Framework streaming pattern:** ```csharp await foreach (AgentRunResponseUpdate update in agent.RunStreamingAsync(userInput, thread, options)) { Console.Write(update); } ``` **Required changes:** 1. Replace `agent.InvokeAsync()` with `agent.RunAsync()` 2. Replace `agent.InvokeStreamingAsync()` with `agent.RunStreamingAsync()` 3. Change return type handling from `IAsyncEnumerable>` to `AgentRunResponse` 4. Change streaming type from `StreamingChatMessageContent` to `AgentRunResponseUpdate` 5. Remove `await foreach` for non-streaming calls 6. Access message content directly from result object instead of iterating ### Options and Configuration Transformation **Replace this Semantic Kernel options pattern:** ```csharp OpenAIPromptExecutionSettings settings = new() { MaxTokens = 1000 }; AgentInvokeOptions options = new() { KernelArguments = new(settings) }; ``` **With this Agent Framework options pattern:** ```csharp ChatClientAgentRunOptions options = new(new ChatOptions { MaxOutputTokens = 1000 }); ``` **Required changes:** 1. Remove `OpenAIPromptExecutionSettings` (or other provider-specific settings) 2. Remove `AgentInvokeOptions` wrapper 3. Remove `KernelArguments` wrapper 4. Replace with `ChatClientAgentRunOptions` containing `ChatOptions` 5. Update property names: `MaxTokens` → `MaxOutputTokens` 6. Pass options directly to `RunAsync()` or `RunStreamingAsync()` methods ### Dependency Injection Transformation **Replace this Semantic Kernel DI pattern:** Different providers require different kernel extensions: ```csharp services.AddKernel().AddOpenAIChatClient(modelId, apiKey); services.AddTransient(sp => new() { Kernel = sp.GetRequiredService(), Instructions = "You are helpful" }); ``` **With this Agent Framework DI pattern:** ```csharp services.AddTransient(sp => new OpenAIClient(apiKey) .GetChatClient(modelId) .CreateAIAgent(instructions: "You are helpful")); ``` **Required changes:** 1. Remove `services.AddKernel()` registration 2. Remove provider-specific kernel extensions (e.g., `.AddOpenAIChatClient()`) 3. Replace `ChatCompletionAgent` with `AIAgent` in service registration 4. Remove `Kernel` dependency from constructor 5. Use direct client creation and extension methods 6. Remove `sp.GetRequiredService()` calls ### Thread Cleanup Transformation **Replace this Semantic Kernel cleanup pattern:** ```csharp await thread.DeleteAsync(); // For hosted threads ``` **With these Agent Framework cleanup patterns:** For every thread created if there's intent to cleanup, the caller should track all the created threads for the provider that support hosted threads for cleanup purposes. ```csharp // For OpenAI Assistants (when cleanup is needed): var assistantClient = new OpenAIClient(apiKey).GetAssistantClient(); await assistantClient.DeleteThreadAsync(thread.ConversationId); // For Azure AI Foundry (when cleanup is needed): var persistentClient = new PersistentAgentsClient(endpoint, credential); await persistentClient.Threads.DeleteThreadAsync(thread.ConversationId); // No thread and agent cleanup is needed for non-hosted agent providers like // - Azure OpenAI Chat Completion // - OpenAI Chat Completion // - Azure OpenAI Responses // - OpenAI Responses ``` **Required changes:** 1. Remove `thread.DeleteAsync()` calls 2. Use provider-specific client for cleanup when required 3. Access thread ID via `thread.ConversationId` property 4. Only implement cleanup for providers that require it (Assistants, Azure AI Foundry) ### Provider-Specific Creation Patterns Use these exact patterns for each provider: **OpenAI Chat Completion:** ```csharp AIAgent agent = new OpenAIClient(apiKey) .GetChatClient(modelId) .CreateAIAgent(instructions: instructions); ``` **OpenAI Assistants (New):** ```csharp AIAgent agent = new OpenAIClient(apiKey) .GetAssistantClient() .CreateAIAgent(modelId, instructions: instructions); ``` **OpenAI Assistants (Existing):** ```csharp AIAgent agent = new OpenAIClient(apiKey) .GetAssistantClient() .GetAIAgent(assistantId); ``` **Azure OpenAI:** ```csharp AIAgent agent = new AzureOpenAIClient(endpoint, credential) .GetChatClient(deploymentName) .CreateAIAgent(instructions: instructions); ``` **Azure AI Foundry (New):** ```csharp AIAgent agent = new PersistentAgentsClient(endpoint, credential) .CreateAIAgent(model: deploymentName, instructions: instructions); ``` **Azure AI Foundry (Existing):** ```csharp AIAgent agent = await new PersistentAgentsClient(endpoint, credential) .GetAIAgentAsync(agentId); ``` **A2A:** ```csharp A2ACardResolver resolver = new(new Uri(agentHost)); AIAgent agent = await resolver.GetAIAgentAsync(); ``` ### Complete Migration Examples #### Basic Agent Creation Transformation **Replace this complete Semantic Kernel pattern:** ```csharp using Microsoft.SemanticKernel; using Microsoft.SemanticKernel.Agents; Kernel kernel = Kernel.CreateBuilder() .AddOpenAIChatClient(modelId, apiKey) .Build(); ChatCompletionAgent agent = new() { Instructions = "You are helpful", Kernel = kernel }; AgentThread thread = new ChatHistoryAgentThread(); ``` **With this complete Agent Framework pattern:** ```csharp using Microsoft.Agents.AI; using OpenAI; AIAgent agent = new OpenAIClient(apiKey) .GetChatClient(modelId) .CreateAIAgent(instructions: "You are helpful"); AgentThread thread = agent.GetNewThread(); ``` #### Tool Registration Transformation **Replace this complete Semantic Kernel tool pattern:** ```csharp [KernelFunction] // Remove this attribute [Description("Get weather information")] static string GetWeather([Description("Location")] string location) => $"Weather in {location}"; KernelFunction function = KernelFunctionFactory.CreateFromMethod(GetWeather); KernelPlugin plugin = KernelPluginFactory.CreateFromFunctions("Weather", [function]); kernel.Plugins.Add(plugin); ``` **With this complete Agent Framework tool pattern:** ```csharp [Description("Get weather information")] // Keep this attribute static string GetWeather([Description("Location")] string location) => $"Weather in {location}"; AIAgent agent = chatClient.CreateAIAgent( instructions: "You are a helpful assistant", tools: [AIFunctionFactory.Create(GetWeather)]); ``` #### Agent Invocation Transformation **Replace this complete Semantic Kernel invocation pattern:** ```csharp OpenAIPromptExecutionSettings settings = new() { MaxTokens = 1000 }; AgentInvokeOptions options = new() { KernelArguments = new(settings) }; await foreach (var result in agent.InvokeAsync(input, thread, options)) { Console.WriteLine(result.Message); } ``` **With this complete Agent Framework invocation pattern:** ```csharp ChatClientAgentRunOptions options = new(new ChatOptions { MaxOutputTokens = 1000 }); AgentRunResponse result = await agent.RunAsync(input, thread, options); Console.WriteLine(result); // Access underlying content when needed: var chatResponse = result.RawRepresentation as ChatResponse; // Access underlying SDK objects via chatResponse?.RawRepresentation ``` ### Usage Metadata Transformation **Replace this Semantic Kernel non-streaming usage pattern:** ```csharp await foreach (var result in agent.InvokeAsync(input, thread, options)) { if (result.Message.Metadata?.TryGetValue("Usage", out object? usage) ?? false) { if (usage is ChatTokenUsage openAIUsage) { Console.WriteLine($"Tokens: {openAIUsage.TotalTokenCount}"); } } } ``` **With this Agent Framework non-streaming usage pattern:** ```csharp AgentRunResponse result = await agent.RunAsync(input, thread, options); Console.WriteLine($"Tokens: {result.Usage.TotalTokenCount}"); ``` **Replace this Semantic Kernel streaming usage pattern:** ```csharp await foreach (StreamingChatMessageContent response in agent.InvokeStreamingAsync(message, agentThread)) { if (response.Metadata?.TryGetValue("Usage", out object? usage) ?? false) { if (usage is ChatTokenUsage openAIUsage) { Console.WriteLine($"Tokens: {openAIUsage.TotalTokenCount}"); } } } ``` **With this Agent Framework streaming usage pattern:** ```csharp await foreach (AgentRunResponseUpdate update in agent.RunStreamingAsync(input, thread, options)) { if (update.Contents.OfType().FirstOrDefault() is { } usageContent) { Console.WriteLine($"Tokens: {usageContent.Details.TotalTokenCount}"); } } ``` ### Breaking Glass Pattern Transformation **Replace this Semantic Kernel breaking glass pattern:** ```csharp await foreach (var content in agent.InvokeAsync(userInput, thread)) { UnderlyingSdkType? underlyingChatMessage = content.Message.InnerContent as UnderlyingSdkType; } ``` **With this Agent Framework breaking glass pattern:** ```csharp var agentRunResponse = await agent.RunAsync(userInput, thread); // If the agent uses a ChatClient the first breaking glass probably will be a Microsoft.Extensions.AI.ChatResponse ChatResponse? chatResponse = agentRunResponse.RawRepresentation as ChatResponse; // If thats the case, to access the underlying SDK types you will need to break glass again. UnderlyingSdkType? underlyingChatMessage = chatResponse?.RawRepresentation as UnderlyingSdkType; ``` **Required changes:** 1. Replace `InnerContent` property access with `RawRepresentation` property access 2. Cast `RawRepresentation` to appropriate type expected 3. If the `RawRepresentation` is a `Microsoft.Extensions.AI` type, break glass again to access the underlying SDK types #### CodeInterpreter Tool Transformation **Replace this Semantic Kernel CodeInterpreter pattern:** ```csharp await foreach (var content in agent.InvokeAsync(userInput, thread)) { bool isCode = content.Message.Metadata?.ContainsKey(AzureAIAgent.CodeInterpreterMetadataKey) ?? false; Console.WriteLine($"# {content.Message.Role}{(isCode ? "\n# Generated Code:\n" : ":")}{content.Message.Content}"); // Process annotations foreach (var item in content.Message.Items) { if (item is AnnotationContent annotation) { Console.WriteLine($"[{item.GetType().Name}] {annotation.Label}: File #{annotation.ReferenceId}"); } else if (item is FileReferenceContent fileReference) { Console.WriteLine($"[{item.GetType().Name}] File #{fileReference.FileId}"); } } } ``` **With this Agent Framework CodeInterpreter pattern:** ```csharp var result = await agent.RunAsync(userInput, thread); Console.WriteLine(result); // Extract chat response MEAI type via first level breaking glass var chatResponse = result.RawRepresentation as ChatResponse; // Extract underlying SDK updates via second level breaking glass var underlyingStreamingUpdates = chatResponse?.RawRepresentation as IEnumerable ?? []; StringBuilder generatedCode = new(); foreach (object? underlyingUpdate in underlyingStreamingUpdates ?? []) { if (underlyingUpdate is RunStepDetailsUpdate stepDetailsUpdate && stepDetailsUpdate.CodeInterpreterInput is not null) { generatedCode.Append(stepDetailsUpdate.CodeInterpreterInput); } } if (!string.IsNullOrEmpty(generatedCode.ToString())) { Console.WriteLine($"\n# {chatResponse?.Messages[0].Role}:Generated Code:\n{generatedCode}"); } ``` **Functional differences:** 1. Code interpreter output is separate from text content, not a metadata property 2. Access code via `RunStepDetailsUpdate.CodeInterpreterInput` instead of metadata 3. Use breaking glass pattern to access underlying SDK objects 4. Process text content and code interpreter output independently #### Provider-Specific Options Configuration For advanced model settings not available in `ChatOptions`, use the `RawRepresentationFactory` property: ```csharp var agentOptions = new ChatClientAgentRunOptions(new ChatOptions { MaxOutputTokens = 8000, // Breaking glass to access provider-specific options RawRepresentationFactory = (_) => new OpenAI.Responses.CreateResponseOptions() { TruncationMode = OpenAI.Responses.ResponseTruncationMode.Auto, } }); ``` **Use this pattern when:** 1. Standard `ChatOptions` properties don't cover required model settings 2. Provider-specific configuration is needed (e.g., truncation mode) 3. Advanced SDK features need to be accessed #### Type-Safe Extension Methods Use provider-specific extension methods for safer breaking glass access: ```csharp using OpenAI; // Brings in extension methods // Type-safe extraction of OpenAI ChatCompletion var chatCompletion = result.AsChatCompletion(); // Access underlying OpenAI objects safely var openAIResponse = chatCompletion.GetRawResponse(); ``` **Available extension methods:** - `result.AsChatCompletion()` for OpenAI providers - `result.GetRawResponse()` for accessing underlying SDK responses - Provider-specific extensions for type-safe casting ### Common Migration Issues and Solutions **Issue: Missing Using Statements** - **Problem**: Compilation errors due to missing namespace imports - **Solution**: Add `using Microsoft.Agents.AI;` and remove `using Microsoft.SemanticKernel.Agents;` **Issue: Tool Function Signatures** - **Problem**: `[KernelFunction]` attributes cause compilation errors - **Solution**: Remove `[KernelFunction]` attributes, keep `[Description]` attributes **Issue: Thread Type Mismatches** - **Problem**: Provider-specific thread constructors not found - **Solution**: Replace all thread constructors with `agent.GetNewThread()` **Issue: Options Configuration** - **Problem**: `AgentInvokeOptions` type not found - **Solution**: Replace with `AgentRunOptions` or `ChatClientAgentRunOptions` containing `ChatOptions` **Issue: Dependency Injection** - **Problem**: `Kernel` service registration not found - **Solution**: Remove `services.AddKernel()`, use direct client registration ### Migration Execution Steps 1. **Update Package References**: Remove SK packages, add AF packages per provider 2. **Update Namespaces**: Replace SK namespaces with AF namespaces 3. **Update Agent Creation**: Remove Kernel, use direct client creation 4. **Update Method Calls**: Replace `InvokeAsync` with `RunAsync` 5. **Update Thread Creation**: Replace provider-specific constructors with `GetNewThread()` 6. **Update Tool Registration**: Remove attributes, use `AIFunctionFactory.Create()` 7. **Update Options**: Replace `AgentInvokeOptions` with provider-specific options 8. **Test and Validate**: Compile and test all functionality ## Provider-Specific Migration Patterns The following sections provide detailed migration patterns for each supported provider, covering package references, agent creation patterns, and provider-specific configurations. ### 1. OpenAI Chat Completion Migration **Remove Semantic Kernel Packages:** ```xml ``` **Add Agent Framework Packages:** ```xml ``` **Before (Semantic Kernel):** ```csharp using Microsoft.SemanticKernel; using Microsoft.SemanticKernel.Agents; Kernel kernel = Kernel.CreateBuilder() .AddOpenAIChatClient(modelId, apiKey) .Build(); ChatCompletionAgent agent = new() { Instructions = "You are a helpful assistant", Kernel = kernel }; AgentThread thread = new ChatHistoryAgentThread(); ``` **After (Agent Framework):** ```csharp using Microsoft.Agents.AI; using OpenAI; AIAgent agent = new OpenAIClient(apiKey) .GetChatClient(modelId) .CreateAIAgent(instructions: "You are a helpful assistant"); AgentThread thread = agent.GetNewThread(); ``` ### 2. Azure OpenAI Chat Completion Migration **Remove Semantic Kernel Packages:** ```xml ``` **Add Agent Framework Packages:** ```xml ``` **Note**: If not using `AzureCliCredential`, you can use `ApiKeyCredential` instead without the `Azure.Identity` package. **Before (Semantic Kernel):** ```csharp using Microsoft.SemanticKernel; using Microsoft.SemanticKernel.Agents; using Azure.Identity; Kernel kernel = Kernel.CreateBuilder() .AddAzureOpenAIChatClient(deploymentName, endpoint, new AzureCliCredential()) .Build(); ChatCompletionAgent agent = new() { Instructions = "You are a helpful assistant", Kernel = kernel }; ``` **After (Agent Framework):** ```csharp using Microsoft.Agents.AI; using Azure.AI.OpenAI; using Azure.Identity; AIAgent agent = new AzureOpenAIClient(new Uri(endpoint), new AzureCliCredential()) .GetChatClient(deploymentName) .CreateAIAgent(instructions: "You are a helpful assistant"); ``` ### 3. OpenAI Assistants Migration **Remove Semantic Kernel Packages:** ```xml ``` **Add Agent Framework Packages:** ```xml ``` **Replace this Semantic Kernel pattern:** ```csharp using Microsoft.SemanticKernel.Agents.OpenAI; using OpenAI.Assistants; AssistantClient assistantClient = new(apiKey); Assistant assistant = await assistantClient.CreateAssistantAsync( modelId, instructions: "You are a helpful assistant"); OpenAIAssistantAgent agent = new(assistant, assistantClient) { Kernel = kernel }; AgentThread thread = new OpenAIAssistantAgentThread(assistantClient); ``` **With this Agent Framework pattern:** **Creating a new assistant:** ```csharp using Microsoft.Agents.AI; using OpenAI; AIAgent agent = new OpenAIClient(apiKey) .GetAssistantClient() .CreateAIAgent(modelId, instructions: "You are a helpful assistant"); AgentThread thread = agent.GetNewThread(); // Cleanup when needed await assistantClient.DeleteThreadAsync(thread.ConversationId); ``` **Retrieving an existing assistant:** ```csharp using Microsoft.Agents.AI; using OpenAI; AIAgent agent = new OpenAIClient(apiKey) .GetAssistantClient() .GetAIAgent(assistantId); // Use existing assistant ID AgentThread thread = agent.GetNewThread(); ``` ### 4. Azure AI Foundry (AzureAIAgent) Migration **Remove Semantic Kernel Packages:** ```xml ``` **Add Agent Framework Packages:** ```xml ``` **Replace these Semantic Kernel patterns:** **Pattern 1: Direct AzureAIAgent creation** ```csharp using Microsoft.SemanticKernel.Agents.AzureAI; using Azure.Identity; AzureAIAgent agent = new( endpoint: new Uri(endpoint), credential: new AzureCliCredential(), projectId: projectId) { Instructions = "You are a helpful assistant" }; AgentThread thread = new AzureAIAgentThread(agent); ``` **Pattern 2: PersistentAgent definition creation** ```csharp // Define the agent PersistentAgent definition = await client.Administration.CreateAgentAsync( deploymentName, tools: [new CodeInterpreterToolDefinition()]); AzureAIAgent agent = new(definition, client); // Create a thread for the agent conversation. AgentThread thread = new AzureAIAgentThread(client); ``` **With these Agent Framework patterns:** **Creating a new agent:** ```csharp using Microsoft.Agents.AI; using Azure.AI.Agents.Persistent; using Azure.Identity; var client = new PersistentAgentsClient(endpoint, new AzureCliCredential()); // Create a new AIAgent using Agent Framework AIAgent agent = client.CreateAIAgent( model: deploymentName, instructions: "You are a helpful assistant", tools: [/* List of specialized Azure.AI.Agents.Persistent.ToolDefinition types */]); AgentThread thread = agent.GetNewThread(); ``` **Retrieving an existing agent:** ```csharp using Microsoft.Agents.AI; using Azure.AI.Agents.Persistent; using Azure.Identity; var client = new PersistentAgentsClient(endpoint, new AzureCliCredential()); // Retrieve an existing AIAgent using its ID AIAgent agent = await client.GetAIAgentAsync(agentId); AgentThread thread = agent.GetNewThread(); ``` ### 5. A2A Migration **Remove Semantic Kernel Packages:** ```xml ``` **Add Agent Framework Packages:** ```xml ``` **Replace this Semantic Kernel pattern:** ```csharp // Create an A2A agent instance using var httpClient = CreateHttpClient(); var client = new A2AClient(url, httpClient); var cardResolver = new A2ACardResolver(url, httpClient); var agentCard = await cardResolver.GetAgentCardAsync(); var agent = new A2AAgent(client, agentCard); ``` **With this Agent Framework pattern:** ```csharp // Initialize an A2ACardResolver to get an A2A agent card. A2ACardResolver agentCardResolver = new(new Uri(a2aAgentHost)); // Create an instance of the AIAgent for an existing A2A agent specified by the agent card. AIAgent agent = await agentCardResolver.GetAIAgentAsync(); ``` ### 6. OpenAI Responses Migration **Remove Semantic Kernel Packages:** ```xml ``` **Add Agent Framework Packages:** ```xml ``` **Replace this Semantic Kernel pattern:** The thread management is done manually with OpenAI Responses in Semantic Kernel, where the thread needs to be passed to the `InvokeAsync` method and updated with the `item.Thread` from the response. ```csharp using Microsoft.SemanticKernel.Agents.OpenAI; // Define the agent OpenAIResponseAgent agent = new(new OpenAIClient(apiKey)) { Name = "ResponseAgent", Instructions = "Answer all queries in English and French.", }; // Initial thread can be null as it will be automatically created AgentThread? agentThread = null; var responseItems = agent.InvokeAsync(new ChatMessageContent(AuthorRole.User, "Input message."), agentThread); await foreach (AgentResponseItem responseItem in responseItems) { // Update the thread to maintain the conversation for future interaction agentThread = responseItem.Thread; WriteAgentChatMessage(responseItem.Message); } ``` **With this Agent Framework pattern:** Agent Framework automatically manages the thread, so there's no need to manually update it. ```csharp using Microsoft.Agents.AI.OpenAI; AIAgent agent = new OpenAIClient(apiKey) .GetOpenAIResponseClient(modelId) .CreateAIAgent( name: "ResponseAgent", instructions: "Answer all queries in English and French.", tools: [/* AITools */]); AgentThread thread = agent.GetNewThread(); var result = await agent.RunAsync(userInput, thread); // The thread will be automatically updated with the new response id from this point ``` ### 7. Azure OpenAI Responses Migration **Remove Semantic Kernel Packages:** ```xml ``` **Add Agent Framework Packages:** ```xml ``` **Replace this Semantic Kernel pattern:** Azure OpenAI Responses uses `AzureOpenAIClient` instead of `OpenAIClient`. The thread management is done manually where the thread needs to be passed to the `InvokeAsync` method and updated with the `item.Thread` from the response. ```csharp using Microsoft.SemanticKernel.Agents.OpenAI; using Azure.AI.OpenAI; // Define the agent OpenAIResponseAgent agent = new(new AzureOpenAIClient(endpoint, new AzureCliCredential())) { Name = "ResponseAgent", Instructions = "Answer all queries in English and French.", }; // Initial thread can be null as it will be automatically created AgentThread? agentThread = null; var responseItems = agent.InvokeAsync(new ChatMessageContent(AuthorRole.User, "Input message."), agentThread); await foreach (AgentResponseItem responseItem in responseItems) { // Update the thread to maintain the conversation for future interaction agentThread = responseItem.Thread; WriteAgentChatMessage(responseItem.Message); } ``` **With this Agent Framework pattern:** Agent Framework automatically manages the thread, so there's no need to manually update it. ```csharp using Microsoft.Agents.AI.OpenAI; using Azure.AI.OpenAI; AIAgent agent = new AzureOpenAIClient(endpoint, new AzureCliCredential()) .GetOpenAIResponseClient(modelId) .CreateAIAgent( name: "ResponseAgent", instructions: "Answer all queries in English and French.", tools: [/* AITools */]); AgentThread thread = agent.GetNewThread(); var result = await agent.RunAsync(userInput, thread); // The thread will be automatically updated with the new response id from this point ``` ### 8. A2A Migration **Remove Semantic Kernel Packages:** ```xml ``` **Add Agent Framework Packages:** ```xml ``` **Replace this Semantic Kernel pattern:** ```csharp using A2A; using Microsoft.SemanticKernel; using Microsoft.SemanticKernel.Agents; using Microsoft.SemanticKernel.Agents.A2A; using var httpClient = CreateHttpClient(); var client = new A2AClient(agentUrl, httpClient); var cardResolver = new A2ACardResolver(url, httpClient); var agentCard = await cardResolver.GetAgentCardAsync(); Console.WriteLine(JsonSerializer.Serialize(agentCard, s_jsonSerializerOptions)); var agent = new A2AAgent(client, agentCard); ``` **With this Agent Framework pattern:** ```csharp using System; using A2A; using Microsoft.Agents.AI; using Microsoft.Agents.AI.A2A; // Initialize an A2ACardResolver to get an A2A agent card. A2ACardResolver agentCardResolver = new(new Uri(a2aAgentHost)); // Create an instance of the AIAgent for an existing A2A agent specified by the agent card. AIAgent agent = await agentCardResolver.GetAIAgentAsync(); ``` ### 9. Unsupported Providers (Require Custom Implementation) #### BedrockAgent Migration **Status**: Hosted Agents is not directly supported in Agent Framework **Status**: Non-Hosted AI Model Agents supported via `ChatClientAgent` **Replace this Semantic Kernel pattern:** ```csharp using Microsoft.SemanticKernel.Agents.Bedrock; // Create a new agent on the Bedrock Agent service and prepare it for use using var client = new AmazonBedrockAgentClient(); using var runtimeClient = new AmazonBedrockAgentRuntimeClient(); var agentModel = await client.CreateAndPrepareAgentAsync(new CreateAgentRequest() { AgentName = agentName, Description = "AgentDescription", Instruction = "You are a helpful assistant", AgentResourceRoleArn = TestConfiguration.BedrockAgent.AgentResourceRoleArn, FoundationModel = TestConfiguration.BedrockAgent.FoundationModel, }); // Create a new BedrockAgent instance with the agent model and the client // so that we can interact with the agent using Semantic Kernel contents. var agent = new BedrockAgent(agentModel, client, runtimeClient); ``` **With this Agent Framework workaround:** Currently there's no support for the Hosted Bedrock Agent service in Agent Framework. For providers like AWS Bedrock that have an `IChatClient` implementation available, use the `ChatClientAgent` directly by providing the `IChatClient` instance to the agent. _Those agents will be purely backed by the AI chat models behavior and will not store any state in the server._ ```csharp using Microsoft.Agents.AI; services.TryAddAWSService(); var serviceProvider = services.BuildServiceProvider(); IAmazonBedrockRuntime runtime = serviceProvider.GetRequiredService(); using var bedrockChatClient = runtime.AsIChatClient(); AIAgent agent = new ChatClientAgent(bedrockChatClient, instructions: "You are a helpful assistant"); ``` ### Unsupported Features that need workarounds The following Semantic Kernel Agents features currently don't have direct equivalents in Agent Framework: #### Plugins Migration **Problem**: Semantic Kernel plugins allowed multiple functions to be registered under a type or object instance **Semantic Kernel pattern** ```csharp // Create plugin with multiple functions public class WeatherPlugin { [KernelFunction, Description("Get current weather")] public string GetCurrentWeather(string location) => $"Weather in {location}: Sunny"; [KernelFunction, Description("Get weather forecast")] public static Task GetForecastAsync(string location, int days) => Task.FromResult($"Forecast for {location}: {days} days"); } kernel.Plugins.AddFromType(); // OR kernel.Plugins.AddFromObject(new WeatherPlugin()); ``` **Agent Framework workaround:** ```csharp // Create individual functions (no plugin grouping) public class WeatherFunctions { [Description("Get current weather")] public static string GetCurrentWeather(string location) => $"Weather in {location}: Sunny"; [Description("Get weather forecast")] public Task GetForecastAsync(string location, int days) => Task.FromResult($"Forecast for {location}: {days} days"); } var weatherService = new WeatherFunctions(); // Register functions individually as tools AITool[] tools = [ AIFunctionFactory.Create(WeatherFunctions.GetCurrentWeather), // Get from type static method AIFunctionFactory.Create(weatherService.GetForecastAsync) // Get from instance method ]; // OR Iterate over the type or instance if many functions are needed for registration AITool[] tools = [ .. typeof(WeatherFunctions) .GetMethods(BindingFlags.Static | BindingFlags.Public) .Select((m) => AIFunctionFactory.Create(m, target: null)), // Get from type static methods .. weatherService.GetType() .GetMethods(BindingFlags.Instance | BindingFlags.Public) .Select((m) => AIFunctionFactory.Create(m, target: weatherService)) // Get from instance methods ]; AIAgent agent = new OpenAIClient(apiKey) .GetChatClient(modelId) .CreateAIAgent( instructions: "You are a weather assistant", tools: tools); ``` #### Prompt Template Migration **Problem**: Agent prompt templating is not yet supported in Agent Framework **Semantic Kernel pattern** ```csharp using Microsoft.SemanticKernel; using Microsoft.SemanticKernel.Agents; var template = "Tell a story about {{$topic}} that is {{$length}} sentences long."; ChatCompletionAgent agent = new(templateFactory: new KernelPromptTemplateFactory(), templateConfig: new(template) { TemplateFormat = PromptTemplateConfig.SemanticKernelTemplateFormat }) { Kernel = kernel, Name = "StoryTeller", Arguments = new KernelArguments() { { "topic", "Dog" }, { "length", "3" }, } }; ``` **Agent Framework workaround** ```csharp using Microsoft.Agents.AI; using Microsoft.SemanticKernel; // Manually render template var template = "Tell a story about {{$topic}} that is {{$length}} sentences long."; var renderedTemplate = await new KernelPromptTemplateFactory() .Create(new PromptTemplateConfig(template)) .RenderAsync(new Kernel(), new KernelArguments() { ["topic"] = "Dog", ["length"] = "3" }); AIAgent agent = new OpenAIClient(apiKey) .GetChatClient(modelId) .CreateAIAgent(instructions: renderedTemplate); // No template variables in invocation - use plain string var result = await agent.RunAsync("What's the weather?", thread); Console.WriteLine(result); ``` ### 10. Function Invocation Filtering **Invocation Context** Semantic Kernel's `IAutoFunctionInvocationFilter` provides a `AutoFunctionInvocationContext` where Agent Framework provides `FunctionInvocationContext` The property mapping guide from a `AutoFunctionInvocationContext` to a `FunctionInvocationContext` is as follows: | SK | AF | | --- | --- | | RequestSequenceIndex | Iteration | | FunctionSequenceIndex | FunctionCallIndex | | ToolCallId | CallContent.CallId | | ChatMessageContent | Messages[0] | | ExecutionSettings | Options | | ChatHistory | Messages | | Function | Function | | Kernel | N/A | | Result | Use `return` from the delegate | | Terminate | Terminate | | CancellationToken | provided via argument to middleware delegate | | Arguments | Arguments | #### Semantic Kernel ```csharp // Filter specifically for functions calling public sealed class CustomAutoFunctionInvocationFilter : IAutoFunctionInvocationFilter { public async Task OnAutoFunctionInvocationAsync(AutoFunctionInvocationContext context, Func next) { Console.WriteLine($"[SK Auto Filter] Auto-invoking function: {context.Function.Name}"); // Check if function should be auto-invoked if (context.Function.Name.Contains("Dangerous")) { Console.WriteLine($"[SK Auto Filter] Skipping dangerous function: {context.Function.Name}"); context.Terminate = true; return; } await next(context); Console.WriteLine($"[SK Auto Filter] Auto-invocation completed for: {context.Function.Name}"); } } var builder = Kernel.CreateBuilder() .AddOpenAIChatClient(modelId, apiKey); // via builder DI var builder = Kernel.CreateBuilder() .AddOpenAIChatClient(modelId, apiKey) .Services .AddSingleton(); // OR via DI services .AddKernel() .AddOpenAIChatClient(modelId, apiKey) .AddSingleton(); // OR register auto function filter directly with the kernel instance kernel.AutoFunctionInvocationFilters.Add(new CustomAutoFunctionInvocationFilter()); // Create agent with filtered kernel ChatCompletionAgent agent = new() { Instructions = "You are a helpful assistant", Kernel = kernel }; ``` #### Agent Framework Agent Framework provides function calling middleware that offers equivalent capabilities to Semantic Kernel's auto function invocation filters: ```csharp // Function calling middleware equivalent to CustomAutoFunctionInvocationFilter async ValueTask CustomAutoFunctionMiddleware( AIAgent agent, FunctionInvocationContext context, Func> next, CancellationToken cancellationToken) { Console.WriteLine($"[AF Middleware] Auto-invoking function: {context.Function.Name}"); // Check if function should be auto-invoked if (context.Function.Name.Contains("Dangerous")) { Console.WriteLine($"[AF Middleware] Skipping dangerous function: {context.Function.Name}"); context.Terminate = true; return "Function execution blocked for security reasons"; } var result = await next(context, cancellationToken); Console.WriteLine($"[AF Middleware] Auto-invocation completed for: {context.Function.Name}"); return result; } // Apply middleware to agent var filteredAgent = originalAgent .AsBuilder() .Use(CustomAutoFunctionMiddleware) .Build(); ``` ### 11. Function Invocation Contexts **Invocation Context** Semantic Kernel's `IAutoFunctionInvocationFilter` provides a `AutoFunctionInvocationContext` where Agent Framework provides `FunctionInvocationContext` The property mapping guide from a `AutoFunctionInvocationContext` to a `FunctionInvocationContext` is as follows: | Semantic Kernel | Agent Framework | | --- | --- | | RequestSequenceIndex | Iteration | | FunctionSequenceIndex | FunctionCallIndex | | ToolCallId | CallContent.CallId | | ChatMessageContent | Messages[0] | | ExecutionSettings | Options | | ChatHistory | Messages | | Function | Function | | Kernel | N/A | | Result | Use `return` from the delegate | | Terminate | Terminate | | CancellationToken | provided via argument to middleware delegate | | Arguments | Arguments | ================================================ FILE: .github/workflows/check-coverage.ps1 ================================================ param ( [string]$JsonReportPath, [double]$CoverageThreshold ) $jsonContent = Get-Content $JsonReportPath -Raw | ConvertFrom-Json $coverageBelowThreshold = $false $nonExperimentalAssemblies = [System.Collections.Generic.HashSet[string]]::new() $assembliesCollection = @( 'Microsoft.SemanticKernel.Abstractions' 'Microsoft.SemanticKernel.Core' 'Microsoft.SemanticKernel.PromptTemplates.Handlebars' 'Microsoft.SemanticKernel.Connectors.OpenAI' 'Microsoft.SemanticKernel.Connectors.AzureOpenAI' 'Microsoft.SemanticKernel.Yaml' 'Microsoft.SemanticKernel.Agents.Abstractions' 'Microsoft.SemanticKernel.Agents.Core' 'Microsoft.SemanticKernel.Agents.OpenAI' ) foreach ($assembly in $assembliesCollection) { $nonExperimentalAssemblies.Add($assembly) } function Get-FormattedValue { param ( [float]$Coverage, [bool]$UseIcon = $false ) $formattedNumber = "{0:N1}" -f $Coverage $icon = if (-not $UseIcon) { "" } elseif ($Coverage -ge $CoverageThreshold) { '✅' } else { '❌' } return "$formattedNumber% $icon" } $lineCoverage = $jsonContent.summary.linecoverage $branchCoverage = $jsonContent.summary.branchcoverage $totalTableData = [PSCustomObject]@{ 'Metric' = 'Total Coverage' 'Line Coverage' = Get-FormattedValue -Coverage $lineCoverage 'Branch Coverage' = Get-FormattedValue -Coverage $branchCoverage } $totalTableData | Format-Table -AutoSize $assemblyTableData = @() foreach ($assembly in $jsonContent.coverage.assemblies) { $assemblyName = $assembly.name $assemblyLineCoverage = $assembly.coverage $assemblyBranchCoverage = $assembly.branchcoverage $isNonExperimentalAssembly = $nonExperimentalAssemblies -contains $assemblyName if ($isNonExperimentalAssembly -and ($assemblyLineCoverage -lt $CoverageThreshold -or $assemblyBranchCoverage -lt $CoverageThreshold)) { $coverageBelowThreshold = $true } $assemblyTableData += [PSCustomObject]@{ 'Assembly Name' = $assemblyName 'Line' = Get-FormattedValue -Coverage $assemblyLineCoverage -UseIcon $isNonExperimentalAssembly 'Branch' = Get-FormattedValue -Coverage $assemblyBranchCoverage -UseIcon $isNonExperimentalAssembly } } $sortedTable = $assemblyTableData | Sort-Object { $nonExperimentalAssemblies -contains $_.'Assembly Name' } -Descending $sortedTable | Format-Table -AutoSize if ($coverageBelowThreshold) { Write-Host "Code coverage is lower than defined threshold: $CoverageThreshold.

In much of Asia this occurs on Thursday local time. Adjusted for daylight savings. Join here: [SK-APAC-OfficeHours](https://aka.ms/sk-apac-officehours). If you have any questions or if you would like to showcase your project(s), please email what you'd like us to cover here: skofficehours[at]microsoft.com. If you are unable to make it live, all meetings will be recorded and posted online. ## Engage on our Community Discord This is a great place to ask questions, share your projects, and get help from the community. Join using our discord link: [aka.ms/SKDiscord](https://aka.ms/SKDiscord) ================================================ FILE: CONTRIBUTING.md ================================================ # Contributing to Semantic Kernel You can contribute to Semantic Kernel with issues and pull requests (PRs). Simply filing issues for problems you encounter is a great way to contribute. Contributing code is greatly appreciated. ## Reporting Issues We always welcome bug reports, API proposals and overall feedback. Here are a few tips on how you can make reporting your issue as effective as possible. ### Where to Report New issues can be reported in our [list of issues](https://github.com/microsoft/semantic-kernel/issues). Before filing a new issue, please search the list of issues to make sure it does not already exist. If you do find an existing issue for what you wanted to report, please include your own feedback in the discussion. Do consider upvoting (👍 reaction) the original post, as this helps us prioritize popular issues in our backlog. ### Writing a Good Bug Report Good bug reports make it easier for maintainers to verify and root cause the underlying problem. The better a bug report, the faster the problem will be resolved. Ideally, a bug report should contain the following information: - A high-level description of the problem. - A _minimal reproduction_, i.e. the smallest size of code/configuration required to reproduce the wrong behavior. - A description of the _expected behavior_, contrasted with the _actual behavior_ observed. - Information on the environment: OS/distribution, CPU architecture, SDK version, etc. - Additional information, e.g. Is it a regression from previous versions? Are there any known workarounds? ## Contributing Changes Project maintainers will merge accepted code changes from contributors. ### DOs and DON'Ts DO's: - **DO** follow the standard coding conventions - [.NET](https://learn.microsoft.com/dotnet/csharp/fundamentals/coding-style/coding-conventions) - [Python](https://pypi.org/project/black/) - [Typescript](https://typescript-eslint.io/rules/)/[React](https://github.com/jsx-eslint/eslint-plugin-react/tree/master/docs/rules) - **DO** give priority to the current style of the project or file you're changing if it diverges from the general guidelines. - **DO** include tests when adding new features. When fixing bugs, start with adding a test that highlights how the current behavior is broken. - **DO** keep the discussions focused. When a new or related topic comes up it's often better to create new issue than to side track the discussion. - **DO** clearly state on an issue that you are going to take on implementing it. - **DO** blog and tweet (or whatever) about your contributions, frequently! DON'Ts: - **DON'T** surprise us with big pull requests. Instead, file an issue and start a discussion so we can agree on a direction before you invest a large amount of time. - **DON'T** commit code that you didn't write. If you find code that you think is a good fit to add to Semantic Kernel, file an issue and start a discussion before proceeding. - **DON'T** submit PRs that alter licensing related files or headers. If you believe there's a problem with them, file an issue and we'll be happy to discuss it. - **DON'T** make new APIs without filing an issue and discussing with us first. ### Breaking Changes Contributions must maintain API signature and behavioral compatibility. Contributions that include breaking changes will be rejected. Please file an issue to discuss your idea or change if you believe that a breaking change is warranted. ### Suggested Workflow We use and recommend the following workflow: 1. Create an issue for your work. - You can skip this step for trivial changes. - Reuse an existing issue on the topic, if there is one. - Get agreement from the team and the community that your proposed change is a good one. - Clearly state that you are going to take on implementing it, if that's the case. You can request that the issue be assigned to you. Note: The issue filer and the implementer don't have to be the same person. 2. Create a personal fork of the repository on GitHub (if you don't already have one). 3. In your fork, create a branch off of main (`git checkout -b mybranch`). - Name the branch so that it clearly communicates your intentions, such as "issue-123" or "githubhandle-issue". 4. Make and commit your changes to your branch. 5. Add new tests corresponding to your change, if applicable. 6. Run the relevant scripts in [the section below](https://github.com/microsoft/semantic-kernel/blob/main/CONTRIBUTING.md#dev-scripts) to ensure that your build is clean and all tests are passing. 7. Create a PR against the repository's **main** branch. - State in the description what issue or improvement your change is addressing. - Verify that all the Continuous Integration checks are passing. 8. Wait for feedback or approval of your changes from the code maintainers. 9. When area owners have signed off, and all checks are green, your PR will be merged. ### Development scripts The scripts below are used to build, test, and lint within the project. - Python: see [python/DEV_SETUP.md](https://github.com/microsoft/semantic-kernel/blob/main/python/DEV_SETUP.md#pipeline-checks). - .NET: - Build/Test: `run build.cmd` or `bash build.sh` - Linting (auto-fix): `dotnet format` - Typescript: - Build/Test: `yarn build` - Linting (auto-fix): `yarn lint:fix` ### Adding Plugins and Memory Connectors When considering contributions to plugins and memory connectors for Semantic Kernel, please note the following guidelines: #### Plugins We appreciate your interest in extending Semantic Kernel's functionality through plugins. However, we want to clarify our approach to hosting plugins within our GitHub repository. To maintain a clean and manageable codebase, we will not be hosting plugins directly in the Semantic Kernel GitHub repository. Instead, we encourage contributors to host their plugin code in separate repositories under their own GitHub accounts or organization. You can then provide a link to your plugin repository in the relevant discussions, issues, or documentation within the Semantic Kernel repository. This approach ensures that each plugin can be maintained independently and allows for easier tracking of updates and issues specific to each plugin. #### Memory Connectors For memory connectors, while we won't be directly adding hosting for them within the Semantic Kernel repository, we highly recommend building memory connectors as separate plugins. Memory connectors play a crucial role in interfacing with external memory systems, and treating them as plugins enhances modularity and maintainability. ### PR - CI Process The continuous integration (CI) system will automatically perform the required builds and run tests (including the ones you are expected to run) for PRs. Builds and test runs must be clean. If the CI build fails for any reason, the PR issue will be updated with a link that can be used to determine the cause of the failure. ================================================ FILE: FEATURE_MATRIX.md ================================================ # Semantic Kernel feature matrix by language This document has been moved to the Semantic Kernel Documentation site.

using Microsoft.SemanticKernel.Agents; var builder = Kernel.CreateBuilder(); builder.AddAzureOpenAIChatCompletion( Environment.GetEnvironmentVariable("AZURE_OPENAI_DEPLOYMENT"), Environment.GetEnvironmentVariable("AZURE_OPENAI_ENDPOINT"), Environment.GetEnvironmentVariable("AZURE_OPENAI_API_KEY") ); var kernel = builder.Build(); ChatCompletionAgent agent = new() { Name = "SK-Agent", Instructions = "You are a helpful assistant.", Kernel = kernel, }; await foreach (AgentResponseItem response in agent.InvokeAsync("Write a haiku about Semantic Kernel.")) { Console.WriteLine(response.Message); } // Output: // Language's essence, // Semantic threads intertwine, // Meaning's core revealed. ``` ### Agent with Plugins - Python Enhance your agent with custom tools (plugins) and structured output: ```python import asyncio from typing import Annotated from pydantic import BaseModel from semantic_kernel.agents import ChatCompletionAgent from semantic_kernel.connectors.ai.open_ai import AzureChatCompletion, OpenAIChatPromptExecutionSettings from semantic_kernel.functions import kernel_function, KernelArguments class MenuPlugin: @kernel_function(description="Provides a list of specials from the menu.") def get_specials(self) -> Annotated[str, "Returns the specials from the menu."]: return """ Special Soup: Clam Chowder Special Salad: Cobb Salad Special Drink: Chai Tea """ @kernel_function(description="Provides the price of the requested menu item.") def get_item_price( self, menu_item: Annotated[str, "The name of the menu item."] ) -> Annotated[str, "Returns the price of the menu item."]: return "$9.99" class MenuItem(BaseModel): price: float name: str async def main(): # Configure structured output format settings = OpenAIChatPromptExecutionSettings() settings.response_format = MenuItem # Create agent with plugin and settings agent = ChatCompletionAgent( service=AzureChatCompletion(), name="SK-Assistant", instructions="You are a helpful assistant.", plugins=[MenuPlugin()], arguments=KernelArguments(settings) ) response = await agent.get_response(messages="What is the price of the soup special?") print(response.content) # Output: # The price of the Clam Chowder, which is the soup special, is $9.99. asyncio.run(main()) ``` ### Agent with Plugin - .NET ```csharp using System.ComponentModel; using Microsoft.SemanticKernel; using Microsoft.SemanticKernel.Agents; using Microsoft.SemanticKernel.ChatCompletion; var builder = Kernel.CreateBuilder(); builder.AddAzureOpenAIChatCompletion( Environment.GetEnvironmentVariable("AZURE_OPENAI_DEPLOYMENT"), Environment.GetEnvironmentVariable("AZURE_OPENAI_ENDPOINT"), Environment.GetEnvironmentVariable("AZURE_OPENAI_API_KEY") ); var kernel = builder.Build(); kernel.Plugins.Add(KernelPluginFactory.CreateFromType()); ChatCompletionAgent agent = new() { Name = "SK-Assistant", Instructions = "You are a helpful assistant.", Kernel = kernel, Arguments = new KernelArguments(new PromptExecutionSettings() { FunctionChoiceBehavior = FunctionChoiceBehavior.Auto() }) }; await foreach (AgentResponseItem response in agent.InvokeAsync("What is the price of the soup special?")) { Console.WriteLine(response.Message); } sealed class MenuPlugin { [KernelFunction, Description("Provides a list of specials from the menu.")] public string GetSpecials() => """ Special Soup: Clam Chowder Special Salad: Cobb Salad Special Drink: Chai Tea """; [KernelFunction, Description("Provides the price of the requested menu item.")] public string GetItemPrice( [Description("The name of the menu item.")] string menuItem) => "$9.99"; } ``` ### Multi-Agent System - Python Build a system of specialized agents that can collaborate: ```python import asyncio from semantic_kernel.agents import ChatCompletionAgent, ChatHistoryAgentThread from semantic_kernel.connectors.ai.open_ai import AzureChatCompletion, OpenAIChatCompletion billing_agent = ChatCompletionAgent( service=AzureChatCompletion(), name="BillingAgent", instructions="You handle billing issues like charges, payment methods, cycles, fees, discrepancies, and payment failures." ) refund_agent = ChatCompletionAgent( service=AzureChatCompletion(), name="RefundAgent", instructions="Assist users with refund inquiries, including eligibility, policies, processing, and status updates.", ) triage_agent = ChatCompletionAgent( service=OpenAIChatCompletion(), name="TriageAgent", instructions="Evaluate user requests and forward them to BillingAgent or RefundAgent for targeted assistance." " Provide the full answer to the user containing any information from the agents", plugins=[billing_agent, refund_agent], ) thread: ChatHistoryAgentThread = None async def main() -> None: print("Welcome to the chat bot!\n Type 'exit' to exit.\n Try to get some billing or refund help.") while True: user_input = input("User:> ") if user_input.lower().strip() == "exit": print("\n\nExiting chat...") return False response = await triage_agent.get_response( messages=user_input, thread=thread, ) if response: print(f"Agent :> {response}") # Agent :> I understand that you were charged twice for your subscription last month, and I'm here to assist you with resolving this issue. Here’s what we need to do next: # 1. **Billing Inquiry**: # - Please provide the email address or account number associated with your subscription, the date(s) of the charges, and the amount charged. This will allow the billing team to investigate the discrepancy in the charges. # 2. **Refund Process**: # - For the refund, please confirm your subscription type and the email address associated with your account. # - Provide the dates and transaction IDs for the charges you believe were duplicated. # Once we have these details, we will be able to: # - Check your billing history for any discrepancies. # - Confirm any duplicate charges. # - Initiate a refund for the duplicate payment if it qualifies. The refund process usually takes 5-10 business days after approval. # Please provide the necessary details so we can proceed with resolving this issue for you. if __name__ == "__main__": asyncio.run(main()) ``` ## Where to Go Next 1. 📖 Try our [Getting Started Guide](https://learn.microsoft.com/en-us/semantic-kernel/get-started/quick-start-guide) or learn about [Building Agents](https://learn.microsoft.com/en-us/semantic-kernel/frameworks/agent/) 2. 🔌 Explore over 100 [Detailed Samples](https://learn.microsoft.com/en-us/semantic-kernel/get-started/detailed-samples) 3. 💡 Learn about core Semantic Kernel [Concepts](https://learn.microsoft.com/en-us/semantic-kernel/concepts/kernel) ### API References - [C# API reference](https://learn.microsoft.com/en-us/dotnet/api/microsoft.semantickernel?view=semantic-kernel-dotnet) - [Python API reference](https://learn.microsoft.com/en-us/python/api/semantic-kernel/semantic_kernel?view=semantic-kernel-python) ## Troubleshooting ### Common Issues - **Authentication Errors**: Check that your API key environment variables are correctly set - **Model Availability**: Verify your Azure OpenAI deployment or OpenAI model access ### Getting Help - Check our [GitHub issues](https://github.com/microsoft/semantic-kernel/issues) for known problems - Search the [Discord community](https://aka.ms/SKDiscord) for solutions - Include your SDK version and full error messages when asking for help ## Join the community We welcome your contributions and suggestions to the SK community!

What metrics are used to measure performance? Microsoft Semantic Kernel metrics include: - Integration Speed: Assessed by the time taken to integrate AI models and initiate functional outputs based on telemetry. - Performance Consistency: Measurements taken to verify the system's reliability based on telemetry. ## What are the limitations of Microsoft Semantic Kernel? Semantic Kernel integrates with Large Language Models (LLMs) to allow AI capabilities to be added to existing application. LLMs have some inherent limitations such as: - Contextual Misunderstanding: The system may struggle with nuanced requests, particularly those involving complex context. - Bias in LLM Outputs: Historical biases in the training data can inadvertently influence model outputs. - Users can mitigate these issues by: - Formulating clear and explicit queries. - Regularly reviewing AI-generated outputs to identify and rectify biases or inaccuracies. - Providing relevant information when prompting the LLM so that it can base it's responses on this data - Not all LLMs support all features uniformly e.g., function calling. Semantic Kernel is constantly evolving and adding new features so: - There are some components still being developed e.g., support for some modalities such as Video and Classification, memory connectors for certain Vector databases, AI connectors for certain AI services. - There are some components that are still experimental, these are clearly flagged and are subject to change. ## What operational factors and settings allow for effective and responsible use of Microsoft Semantic Kernel? Operational factors and settings for optimal use include: - Custom Configuration Options: Users can tailor system parameters to match specific application needs, such as output style or verbosity. - Safe Operating Parameters: The system operates best within defined ranges of input complexity and length, ensuring reliability and safety. - Real-Time Monitoring: System behavior should be regularly monitored to detect unexpected patterns or malfunctions promptly. - Incorporate RAI and safety tools like Prompt Shield with filters to ensure responsible use. ### Plugins and Extensibility #### What are plugins and how does Microsoft Semantic Kernel use them? Plugins are API calls that enhance and extend the capabilities of Microsoft Semantic Kernel by integrating with other services. They can be developed internally or by third-party developers, offering functionalities that users can toggle on or off based on their requirements. The kernel supports OpenAPI specifications, allowing for easy integration and sharing of plugins within developer teams. #### What data can Microsoft Semantic Kernel provide to plugins? What permissions do Microsoft Semantic Kernel plugins have? Plugins can access essential user information necessary for their operation, such as: - Input Context: Information directly related to the queries and commands issued to the system. - Execution Data: Results and performance metrics from previous operations, provided they adhere to user privacy standards. Developers retain control over plugin permissions, choosing what information plugins can access or transmit, ensuring compliance with data protection protocols. - Semantic Kernel supports filters which allow developers to integrate with RAI solutions #### What kinds of issues may arise when using Microsoft Semantic Kernel enabled with plugins? Potential issues that may arise include: - Invocation Failures: Incorrectly triggered plugins can result in unexpected outputs. - Output Misinformation: Errors in plugin handling can lead to generation of inaccurate or misleading results. - Dependency Compatibility: Changes in external dependencies may affect plugin functionality. To prevent these issues, users are advised to keep plugins updated and to rigorously test their implementations for stability and accuracy #### When working with AI, the developer can enable content moderation in the AI platforms used, and has complete control on the prompts being used, including the ability to define responsible boundaries and guidelines. For instance: - When using Azure OpenAI, by default the service includes a content filtering system that works alongside core models. This system works by running both the prompt and completion through an ensemble of classification models aimed at detecting and preventing the output of harmful content. In addition to the content filtering system, the Azure OpenAI Service performs monitoring to detect content and/or behaviors that suggest use of the service in a manner that might violate applicable product terms. The filter configuration can be adjusted, for example to block also "low severity level" content. See here for more information. - The developer can integrate Azure AI Content Safety to detect harmful user-generated and AI-generated content, including text and images. The service includes an interactive Studio online tool with templates and customized workflows. See here for more information. - When using OpenAI the developer can integrate OpenAI Moderation to identify problematic content and take action, for instance by filtering it. See here for more information. - Other AI providers provide content moderation and moderation APIs, which developers can integrate with Node Engine. #### If a sequence of components are run, additional risks/failures may arise when using non-deterministic behavior. To mitigate this, developers can: Implement safety measures and bounds on each component to prevent undesired outcomes. Add output to the user to maintain control and awareness of the system's state. In multi-agent scenarios, build in places that prompt the user for a response, ensuring user involvement and reducing the likelihood of undesired results due to multi-agent looping. ================================================ FILE: docs/COSINE_SIMILARITY.md ================================================ # Cosine Similarity Cosine similarity is a measure of the degree of similarity between two vectors in a multi-dimensional space. It is commonly used in artificial intelligence and natural language processing to compare [embeddings](EMBEDDINGS.md), which are numerical representations of words or other objects. The cosine similarity between two vectors is calculated by taking the [dot product](DOT_PRODUCT.md) of the two vectors and dividing it by the product of their magnitudes. This results in a value between -1 and 1, where 1 indicates that the two vectors are identical, 0 indicates that they are orthogonal (i.e., have no correlation), and -1 indicates that they are opposite. Cosine similarity is particularly useful when working with high-dimensional data such as word embeddings because it takes into account both the magnitude and direction of each vector. This makes it more robust than other measures like [Euclidean distance](EUCLIDEAN_DISTANCE.md), which only considers the magnitude. One common use case for cosine similarity is to find similar words based on their embeddings. For example, given an embedding for "cat", we can use cosine similarity to find other words with similar embeddings, such as "kitten" or "feline". This can be useful for tasks like text classification or sentiment analysis where we want to group together semantically related words. Another application of cosine similarity is in recommendation systems. By representing items (e.g., movies, products) as vectors, we can use cosine similarity to find items that are similar to each other or to a particular item of interest. This allows us to make personalized recommendations based on a user's past behavior or preferences. Overall, cosine similarity is an essential tool for developers working with AI and embeddings. Its ability to capture both magnitude and direction makes it well suited for high-dimensional data, and its applications in natural language processing and recommendation systems make it a valuable tool for building intelligent applications. # Applications Some examples about cosine similarity applications. 1. Recommender Systems: Cosine similarity can be used to find similar items or users in a recommendation system, based on their embedding vectors. 2. Document Similarity: Cosine similarity can be used to compare the similarity of two documents by representing them as embedding vectors and calculating the cosine similarity between them. 3. Image Recognition: Cosine similarity can be used to compare the embeddings of two images, which can help with image recognition tasks. 4. Natural Language Processing: Cosine similarity can be used to measure the semantic similarity between two sentences or paragraphs by comparing their embedding vectors. 5. Clustering: Cosine similarity can be used as a distance metric for clustering algorithms, helping group similar data points together. 6. Anomaly Detection: Cosine similarity can be used to identify anomalies in a dataset by finding data points that have a low cosine similarity with other data points in the dataset. ================================================ FILE: docs/DOT_PRODUCT.md ================================================ # Dot Product Dot product is a mathematical operation that takes two equal-length vectors and returns a single scalar value. It is also known as the scalar product or inner product. The dot product of two vectors is calculated by multiplying corresponding elements of each vector and then summing the results. The dot product has many applications in computer science, particularly in artificial intelligence and machine learning. One common use case for the dot product is to measure the similarity between two vectors, such as word [embeddings](EMBEDDINGS.md) or image embeddings. This can be useful when trying to find similar words or images in a dataset. In AI, the dot product can be used to calculate the [cosine similarity](COSINE_SIMILARITY.md) between two vectors. Cosine similarity measures the angle between two vectors, with a smaller angle indicating greater similarity. This can be useful when working with high-dimensional data where [Euclidean distance](EUCLIDEAN_DISTANCE.md) may not be an accurate measure of similarity. Another application of the dot product in AI is in neural networks, where it can be used to calculate the weighted sum of inputs to a neuron. This calculation is essential for forward propagation in neural networks. Overall, the dot product is an important operation for software developers working with AI and embeddings. It provides a simple yet powerful way to measure similarity between vectors and perform calculations necessary for neural networks. # Applications Some examples about dot product applications. 1. Recommender systems: Dot product can be used to measure the similarity between two vectors representing users or items in a recommender system, helping to identify which items are most likely to be of interest to a particular user. 2. Natural Language Processing (NLP): In NLP, dot product can be used to find the cosine similarity between word embeddings, which is useful for tasks such as finding synonyms or identifying related words. 3. Image recognition: Dot product can be used to compare image embeddings, allowing for more accurate image classification and object detection. 4. Collaborative filtering: By taking the dot product of user and item embeddings, collaborative filtering algorithms can predict how much a particular user will like a particular item. 5. Clustering: Dot product can be used as a distance metric when clustering data points in high-dimensional spaces, such as when working with text or image embeddings. 6. Anomaly detection: By comparing the dot product of an embedding with those of its nearest neighbors, it is possible to identify data points that are significantly different from others in their local neighborhood, indicating potential anomalies. ================================================ FILE: docs/EMBEDDINGS.md ================================================ # Embeddings Embeddings are a powerful tool for software developers working with artificial intelligence and natural language processing. They allow computers to understand the meaning of words in a more sophisticated way, by representing them as high-dimensional vectors rather than simple strings of characters. Embeddings work by mapping each word in a vocabulary to a point in a high-dimensional space. This space is designed so that words with similar meanings are located near each other. This allows algorithms to identify relationships between words, such as synonyms or antonyms, without needing explicit rules or human supervision. One popular method for creating embeddings is Word2Vec [[1]](https://arxiv.org/abs/1301.3781)[[2]](https://arxiv.org/abs/1310.4546), which uses neural networks to learn the relationships between words from large amounts of text data. Other methods include GloVe and [FastText](https://research.facebook.com/downloads/fasttext/). These methods all have different strengths and weaknesses, but they share the common goal of creating meaningful representations of words that can be used in machine learning models. Embeddings can be used in many different applications, including sentiment analysis, document classification, and recommendation systems. They are particularly useful when working with unstructured text data where traditional methods like bag-of-words models struggle, and are a fundamental part of **SK Semantic Memory**. **Semantic Memory** is similar to how the human brain stores and retrieves knowledge about the world. Embeddings are used to create a semantic memory by **representing concepts or entities as vectors in a high-dimensional space**. This approach allows the model to learn relationships between concepts and make inferences based on similarity or distance between vector representations. For example, the Semantic Memory can be trained to understand that "Word" and "Excel" are related concepts because they are both document types and both Microsoft products, even though they use different file formats and provide different features. This type of memory is useful in many applications, including question-answering systems, natural language understanding, and knowledge graphs. Software developers can use pre-trained embedding model, or train their one with their own custom datasets. Pre-trained embedding models have been trained on large amounts of data and can be used out-of-the-box for many applications. Custom embedding models may be necessary when working with specialized vocabularies or domain-specific language. Overall, embeddings are an essential tool for software developers working with AI and natural language processing. They provide a powerful way to represent and understand the meaning of words in a computationally efficient manner. ## Applications Some examples about embeddings applications. 1. Semantic Memory: Embeddings can be used to create a semantic memory, by which a machine can learn to understand the meanings of words and sentences and can understand the relationships between them. 2. Natural Language Processing (NLP): Embeddings can be used to represent words or sentences in NLP tasks such as sentiment analysis, named entity recognition, and text classification. 3. Recommender systems: Embeddings can be used to represent the items in a recommender system, allowing for more accurate recommendations based on similarity between items. 4. Image recognition: Embeddings can be used to represent images in computer vision tasks such as object detection and image classification. 5. Anomaly detection: Embeddings can be used to represent data points in high-dimensional datasets, making it easier to identify outliers or anomalous data points. 6. Graph analysis: Embeddings can be used to represent nodes in a graph, allowing for more efficient graph analysis and visualization. 7. Personalization: Embeddings can be used to represent users in personalized recommendation systems or personalized search engines. ## Vector Operations used with Embeddings - [Cosine Similarity](COSINE_SIMILARITY.md) - [Dot Product](DOT_PRODUCT.md) - [Euclidean Distance](EUCLIDEAN_DISTANCE.md) ================================================ FILE: docs/EUCLIDEAN_DISTANCE.md ================================================ # Euclidean Distance Euclidean distance is a mathematical concept that measures the straight-line distance between two points in a Euclidean space. It is named after the ancient Greek mathematician Euclid, who is often referred to as the "father of geometry". The formula for calculating Euclidean distance is based on the Pythagorean Theorem and can be expressed as: $$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$$ For higher dimensions, this formula can be generalized to: $$d(p, q) = \sqrt{\sum\limits_{i\=1}^{n} (q_i - p_i)^2}$$ Euclidean distance has many applications in computer science and artificial intelligence, particularly when working with [embeddings](EMBEDDINGS.md). Embeddings are numerical representations of data that capture the underlying structure and relationships between different data points. They are commonly used in natural language processing, computer vision, and recommendation systems. When working with embeddings, it is often necessary to measure the similarity or dissimilarity between different data points. This is where Euclidean distance comes into play. By calculating the Euclidean distance between two embeddings, we can determine how similar or dissimilar they are. One common use case for Euclidean distance in AI is in clustering algorithms such as K-means. In this algorithm, data points are grouped together based on their proximity to one another in a multi-dimensional space. The Euclidean distance between each point and the centroid of its cluster is used to determine which points belong to which cluster. Another use case for Euclidean distance is in recommendation systems. By calculating the Euclidean distance between different items' embeddings, we can determine how similar they are and make recommendations based on that information. Overall, Euclidean distance is an essential tool for software developers working with AI and embeddings. It provides a simple yet powerful way to measure the similarity or dissimilarity between different data points in a multi-dimensional space. # Applications Some examples about Euclidean distance applications. 1. Recommender systems: Euclidean distance can be used to measure the similarity between items in a recommender system, helping to provide more accurate recommendations. 2. Image recognition: By calculating the Euclidean distance between image embeddings, it is possible to identify similar images or detect duplicates. 3. Natural Language Processing: Measuring the distance between word embeddings can help with tasks such as semantic similarity and word sense disambiguation. 4. Clustering: Euclidean distance is commonly used as a metric for clustering algorithms, allowing them to group similar data points together. 5. Anomaly detection: By calculating the distance between data points, it is possible to identify outliers or anomalies in a dataset. ================================================ FILE: docs/FAQS.md ================================================ # Frequently Asked Questions ### How do I get access to nightly builds?

It should feel natural to a Java developer. * Different language versions should be consistent with the .Net implementation. In cases of conflict, consistency with Java conventions is the highest priority. * The SK for Java and .Net should feel like a single product developed by a single team. * There should be feature parity between Java and .Net.

Feel free to remove any of them. status: accepted contact: markwallace-microsoft date: 2023-06-16 deciders: shawncal,dluc consulted: informed: --- # Add support for multiple native function arguments of many types ## Context and Problem Statement Move native functions closer to a normal C# experience. ## Decision Drivers - Native skills can now have any number of parameters. The parameters are populated from context variables of the same name. If no context variable exists for that name, it'll be populated with a default value if one was supplied via either an attribute or a default parameter value, or if there is none, the function will fail to be invoked. The first parameter may also be populated from "input" if it fails to get input by its name or default value. - Descriptions are now specified with the .NET DescriptionAttribute, and DefaultValue with the DefaultValueAttribute. The C# compiler is aware of the DefaultValueAttribute and ensures the type of the value provided matches that of the type of the parameter. Default values can now also be specified using optional parameter values. - SKFunction is now purely a marker attribute, other than for sensitivity. It's sole purpose is to subset which public members are imported as native functions when a skill is imported. It was already the case that the attribute wasn't needed when importing a function directly from a delegate; that requirement has also been lifted when importing from a MethodInfo. - SKFunctionContextParameterAttribute has been obsoleted and will be removed subsequently. DescriptionAttribute, DefaultValueAttribute, and SKName attribute are used instead. In rare situations where the method needs access to a variable that's not defined in its signature, it can use the SKParameter attribute on the method, which does have Description and DefaultValue optional properties. - SKFunctionInputAttribute has been obsoleted and will be removed subsequently. DescriptionAttribute, DefaultValueAttribute, and SKName attribute are used instead (the latter with "Input" as the name). However, the need to use SKName should be exceedingly rare. - InvokeAsync will now catch exceptions and store the exception into the context. This means native skills should handle all failures by throwing exceptions rather than by directly interacting with the context. - Updated name selection heuristic to strip off an "Async" suffix for async methods. There are now very few reasons to use [SKName] on a method. - Added support for ValueTasks as return types, just for completeness so that developers don't need to think about it. It just works. - Added ability to accept an ILogger or CancellationToken into a method; they're populated from the SKContext. With that, there are very few reasons left to pass an SKContext into a native function. - Added support for non-string arguments. All C# primitive types and many core .NET types are supported, with their corresponding TypeConverters used to parse the string context variable into the appropriate type. Custom types attributed with TypeConverterAttribute may also be used, and the associated TypeConverter will be used as is appropriate. It's the same mechanism used by UI frameworks like WinForms as well as ASP.NET MVC. - Similarly, added support for non-string return types. ## Decision Outcome [PR 1195](https://github.com/microsoft/semantic-kernel/pull/1195) ## More Information **Example** _Before_: ```C# [SKFunction("Adds value to a value")] [SKFunctionName("Add")] [SKFunctionInput(Description = "The value to add")] [SKFunctionContextParameter(Name = "Amount", Description = "Amount to add")] public Task AddAsync(string initialValueText, SKContext context) { if (!int.TryParse(initialValueText, NumberStyles.Any, CultureInfo.InvariantCulture, out var initialValue)) { return Task.FromException(new ArgumentOutOfRangeException( nameof(initialValueText), initialValueText, "Initial value provided is not in numeric format")); } string contextAmount = context["Amount"]; if (!int.TryParse(contextAmount, NumberStyles.Any, CultureInfo.InvariantCulture, out var amount)) { return Task.FromException(new ArgumentOutOfRangeException( nameof(context), contextAmount, "Context amount provided is not in numeric format")); } var result = initialValue + amount; return Task.FromResult(result.ToString(CultureInfo.InvariantCulture)); } ``` _After_: ```C# [SKFunction, Description("Adds an amount to a value")] public int Add( [Description("The value to add")] int value, [Description("Amount to add")] int amount) => value + amount; ``` **Example** _Before_: ```C# [SKFunction("Wait a given amount of seconds")] [SKFunctionName("Seconds")] [SKFunctionInput(DefaultValue = "0", Description = "The number of seconds to wait")] public async Task SecondsAsync(string secondsText) { if (!decimal.TryParse(secondsText, NumberStyles.Any, CultureInfo.InvariantCulture, out var seconds)) { throw new ArgumentException("Seconds provided is not in numeric format", nameof(secondsText)); } var milliseconds = seconds * 1000; milliseconds = (milliseconds > 0) ?

Feel free to remove any of them. status: accepted contact: SergeyMenshykh date: 2023-06-23 deciders: shawncal consulted: stephentoub informed: --- # Error handling improvements ## Disclaimer This ADR describes problems and their solutions for improving the error handling aspect of SK. It does not address logging, resiliency, or observability aspects. ## Context and Problem Statement Currently, there are several aspects of error handling in SK that can be enhanced to simplify SK code and SK client code, while also ensuring consistency and maintainability: - **Exception propagation**. SK has a few public methods, like Kernel.RunAsync and SKFunction.InvokeAsync, that handle exceptions in a non-standard way. Instead of throwing exceptions, they catch and store them within the SKContext. This deviates from the standard error handling approach in .NET, which expects a method to either execute successfully if its contract is fulfilled or throw an exception if the contract is violated. Consequently, when working with the .NET version of the SK SDK, it becomes challenging to determine whether a method executed successfully or failed without analyzing specific properties of the SKContext instance. This can lead to a frustrating experience for developers using the .NET SK SDK. - **Improper exception usage**. Some SK components use custom SK exceptions instead of standard .NET exceptions to indicate invalid arguments, configuration issues, and so on. This deviates from the standard approach for error handling in .NET and may frustrate SK client code developers. - **Exception hierarchy**. Half of the custom SK exceptions are derived from SKException, while the other half are directly derived from Exception. This inconsistency in the exception hierarchy does not contribute to a cohesive exception model. - **Unnecessary and verbose exceptions** A few SK components, such as the Kernel or Planner, have exceptions at their level, namely PlanningException or KernelException, that are not truly necessary and can be easily replaced by SKException and a few of its derivatives. SK clients might become dependent on them, making it challenging to remove them later if SK needs to discontinue their usage. Additionally, SK has an exception type for each SK memory connector - PineconeMemoryException, QdrantMemoryException that does not add any additional information and only differs by name while having the same member signatures. This makes it impossible for SK client code to handle them in a consolidated manner. Instead of having a single catch block, SK client code needs to include a catch block for each component implementation. Moreover, SK client code needs to be updated every time a new component implementation is added or removed. - **Missing original exception details**. Certain SK exceptions do not preserve the original failure or exception details and do not expose them through their properties. This omission prevents SK client code from understanding the problem and handling it properly. ## Decision Drivers - Exceptions should be propagated to the SK client code instead of being stored in the SKContext. This adjustment will bring SK error handling in line with the .NET approach. - The SK exception hierarchy should be designed following the principle of "less is more." It is easier to add new exceptions later, but removing them can be challenging. - .NET standard exception types should be preferred over SK custom ones because they are easily recognizable, do not require any maintenance, can cover common error scenarios, and provide meaningful and standardized error messages. - Exceptions should not be wrapped in SK exceptions when passing them up to a caller, unless it helps in constructing actionable logic for either SK or SK client code. ## Considered Options - Simplify existing SK exception hierarchy by removing all custom exceptions types except the SKException one and any other type that is actionable. Use SKException type instead of the removed ones unless more details need to be conveyed in which case create a derived specific exception. - Modify SK code to throw .NET standard exceptions, such as ArgumentOutOfRangeException or ArgumentNullException, when class argument values are not provided or are invalid, instead of throwing custom SK exceptions. Analyze SK exception usage to identify and fix other potential areas where standard .NET exceptions can be used instead. - Remove any code that wraps unhandled exceptions into AIException or any other SK exception solely for the purpose of wrapping. In most cases, this code does not provide useful information to action on it, apart from a generic and uninformative "Something went wrong" message. - Identify all cases where the original exception is not preserved as an inner exception of the rethrown SK exception, and address them. - Create a new exception HttpOperationException, which includes a StatusCode property, and implement the necessary logic to map the exception from HttpStatusCode, HttpRequestException, or Azure.RequestFailedException. Update existing SK code that interacts with the HTTP stack to throw HttpOperationException in case of a failed HTTP request and assign the original exception as its inner exception. - Modify all SK components that currently store exceptions to SK context to rethrow them instead. - Simplify the SK critical exception handling functionality by modifying the IsCriticalException extension method to exclude handling of StackOverflowException and OutOfMemoryException exceptions. This is because the former exception is not thrown, so the calling code won't be executed, while the latter exception doesn't necessarily prevent the execution of recovery code. ================================================ FILE: docs/decisions/0005-kernel-hooks-phase1.md ================================================ --- # These are optional elements.

Allowing it to modify the prompt, abort the execution, or modify the output and many other scenarios as follows: - Pre-Execution / Function Invoking - Get: SKContext - Set: Modify input parameters sending to the function - Set: Abort/Cancel pipeline execution - Set: Skip function execution - Post-Execution / Function Invoked - Get: LLM Model Result (Tokens Usage, Stop Sequence, ...) - Get: SKContext - Get: Output parameters - Set: Modify output parameters content (before returning the output) - Set: Cancel pipeline execution - Set: Repeat function execution ## Out of Scope (Will be in phase 2) - Pre-Execution / Function Invoking - Get: Rendered Prompt - Get: Current settings used - Set: Modify the Rendered Prompt - Post-Execution / Function Invoked - Get: Rendered Prompt - Get: Current settings used ## Decision Drivers - Architecture changes and the associated decision making process should be transparent to the community. - Decision records are stored in the repository and are easily discoverable for teams involved in the various language ports. - Simple, Extensible and easy to understand. ## Considered Options 1. Callback Registration + Recursive 2. Single Callback 3. Event Based Registration 4. Middleware 5. ISKFunction Event Support Interfaces ## Pros and Cons of the Options ### 1. Callback Registration Recursive Delegate (Kernel, Plan, Function) - Specified on plan and function level as a configuration be able to specify what are the callback Handlers that will be triggered. Pros: - Common pattern for observing and also changing data exposed as parameter into the delegate signature for (Get/Set) scenarios - Registering a callback gives back the registration object that can be used to cancel the execution of the function in the future. - Recursive approach, allows to register multiple callbacks for the same event, and also allows to register callbacks on top of pre existing callbacks. Cons: - Registrations may use more memory and might not be garbage collected in the recursive approach, only when the function or the plan is disposed. ### 2. Single Callback Delegate (Kernel, Plan, Function) - Specified on kernel level as a configuration be able to specify what are the callback Handlers that will be triggered. - Specified on function creation: As part of the function constructor be able to specify what are the callback Handlers that will be triggered. - Specified on function invocation: As part of the function invoke be able to specify what are the callback Handlers as a parameter that will be triggered. Pros: - Common pattern for observing and also changing data exposed as parameter into the delegate signature for (Get/Set) scenarios Cons: - Limited to only one method observing a specific event (Pre Post and InExecution). - Function When used as parameter, three new parameters would be needed as part of the function. (Specified on function invocation) - Extra Cons on ### 3. Event Base Registration (Kernel only) Expose events on both IKernel and ISKFunction that the call can can be observing to interact. Pros: - Multiple Listeners can registered for the same event - Listeners can be registered and unregistered at will - Common pattern (EventArgs) for observing and also changing data exposed as parameter into the event signature for (Get/Set) scenarios Cons: - Event handlers are void, making the EventArgs by reference the only way to modify the data. - Not clear how supportive is this approach for asynchronous pattern/multi threading - Won't support `ISKFunction.InvokeAsync` ### 4. Middleware (Kernel Only) Specified on Kernel level, and would only be used using IKernel.RunAsync operation, this pattern would be similar to asp.net core middlewares, running the pipelines with a context and a requestdelegate next for controlling (Pre/Post conditions) Pros: - Common pattern for handling Pre/Post Setting/Filtering data Cons: - Functions can run on their own instance, middlewares suggest more complexity and the existence of an external container/manager (Kernel) to intercept/observe function calls. ### 5. ISKFunction Event Support Interfaces ```csharp class Kernel : IKernel { RunAsync() { var functionInvokingArgs = await this.TriggerEvent(this.FunctionInvoking, skFunction, context); var functionResult = await skFunction.InvokeAsync(context, cancellationToken: cancellationToken); var functionInvokedArgs = await this.TriggerEvent( this.FunctionInvoked, skFunction, context); } private TEventArgs? TriggerEvent(EventHandler? eventHandler, ISKFunction function, SKContext context) where TEventArgs : SKEventArgs { if (eventHandler is null) { return null; } if (function is ISKFunctionEventSupport supportedFunction) { var eventArgs = await supportedFunction.PrepareEventArgsAsync(context); eventHandler.Invoke(this, eventArgs); return eventArgs; } // Think about allowing to add data with the extra interface. // If a function don't support the specific event we can: return null; // Ignore or Throw. throw new NotSupportedException($"The provided function \"{function.Name}\" does not supports and implements ISKFunctionHandles<{typeof(TEventArgs).Name}>"); } } public interface ISKFunctionEventSupport where TEventArgs : SKEventArgs { Task PrepareEventArgsAsync(SKContext context, TEventArgs? eventArgs = null); } class SemanticFunction : ISKFunction, ISKFunctionEventSupport, ISKFunctionEventSupport { public FunctionInvokingEventArgs PrepareEventArgsAsync(SKContext context, FunctionInvokingEventArgs? eventArgs = null) { var renderedPrompt = await this.RenderPromptTemplateAsync(context); context.Variables.Set(SemanticFunction.RenderedPromptKey, renderedPrompt); return new SemanticFunctionInvokingEventArgs(this.Describe(), context); // OR Metadata Dictionary return new FunctionInvokingEventArgs(this.Describe(), context, new Dictionary() { { RenderedPrompt, renderedPrompt } }); } public FunctionInvokedEventArgs PrepareEventArgsAsync(SKContext context, FunctionInvokedEventArgs? eventArgs = null) { return Task.FromResult(new SemanticFunctionInvokedEventArgs(this.Describe(), context)); } } public sealed class SemanticFunctionInvokedEventArgs : FunctionInvokedEventArgs { public SemanticFunctionInvokedEventArgs(FunctionDescription functionDescription, SKContext context) : base(functionDescription, context) { _context = context; Metadata[RenderedPromptKey] = this._context.Variables[RenderedPromptKey]; } public string? RenderedPrompt => this.Metadata[RenderedPromptKey]; } public sealed class SemanticFunctionInvokingEventArgs : FunctionInvokingEventArgs { public SemanticFunctionInvokingEventArgs(FunctionDescription functionDescription, SKContext context) : base(functionDescription, context) { _context = context; } public string? RenderedPrompt => this._context.Variables[RenderedPromptKey]; } ``` ### Pros and Cons Pros: - `Kernel` is not aware of `SemanticFunction` implementation details or any other `ISKFunction` implementation - Extensible to show dedicated EventArgs per custom `ISKFunctions` implementation, including prompts for semantic functions - Extensible to support future events on the Kernel thru the `ISKFunctionEventSupport` interface - Functions can have their own EventArgs specialization. - Interface is optional, so custom `ISKFunctions` can choose to implement it or not Cons: - Any custom functions now will have to responsibility implement the `ISKFunctionEventSupport` interface if they want to support events. - `Kernel` will have to check if the function implements the interface or not, and if not, it will have to throw an exception or ignore the event. - Functions implementations that once were limited to InvokeAsync now need to be scattered across multiple places and handle the state of the execution related to content that needs to be get at the beginning or at the end of the invocation. ## Main Questions - Q: Post Execution Handlers should execute right after the LLM result or before the end of the function execution itself? A: Currently post execution Handlers are executed after function execution. - Q: Should Pre/Post Handlers be many (pub/sub) allowing registration/deregistration? A: By using the standard .NET event implementation, this already supports multiple registrations as well as deregistrations managed by the caller. - Q: Setting Handlers on top of pre existing Handlers should be allowed or throw an error? A: By using the standard .NET event implementation, the standard behavior will not throw an error and will execute all the registered handlers. - Q: Setting Handlers on Plans should automatically cascade this Handlers for all the inner steps + overriding existing ones in the process? A: Handlers will be triggered before and after each step is executed the same way the Kernel RunAsync pipeline works. - Q: When a pre function execution handler intents to cancel the execution, should further handlers in the chain be called or not? A: Currently the standard .net behavior is to call all the registered handlers. This way function execution will solely depends on the final state of the Cancellation Request after all handlers were called. ## Decision Outcome Chosen option: **3. Event Base Registration (Kernel only)** This approach is the simplest and take the benefits of the standard .NET event implementation. Further changes will be implemented to fully support all the scenarios in phase 2. ================================================ FILE: docs/decisions/0006-open-api-dynamic-payload-and-namespaces.md ================================================ --- status: superseded by [ADR-0062](0062-open-api-payload.md) contact: SergeyMenshykh date: 2023-08-15 deciders: shawncal consulted: informed: --- # Dynamic payload building for PUT and POST RestAPI operations and parameter namespacing ## Context and Problem Statement Currently, the SK OpenAPI does not allow the dynamic creation of payload/body for PUT and POST RestAPI operations, even though all the required metadata is available. One of the reasons the functionality was not fully developed originally, and eventually removed is that JSON payload/body content of PUT and POST RestAPI operations might contain properties with identical names at various levels. It was not clear how to unambiguously resolve their values from the flat list of context variables. Another reason the functionality has not been added yet is that the 'payload' context variable, along with RestAPI operation data contract schema(OpenAPI, JSON schema, Typings?) should have been sufficient for LLM to provide fully fleshed-out JSON payload/body content without the need to build it dynamically. ## Decision Drivers - Create a mechanism that enables the dynamic construction of the payload/body for PUT and POST RestAPI operations. - Develop a mechanism(namespacing) that allows differentiation of payload properties with identical names at various levels for PUT and POST RestAPI operations. - Aim to minimize breaking changes and maintain backward compatibility of the code as much as possible. ## Considered Options - Enable the dynamic creation of payload and/or namespacing by default. - Enable the dynamic creation of payload and/or namespacing based on configuration. ## Decision Outcome Chosen option: "Enable the dynamic creation of payload and/or namespacing based on configuration". This option keeps things compatible, so the change won't affect any SK consumer code. Additionally, it lets SK consumer code easily control both mechanisms, turning them on or off based on the scenario. ## Additional details ### Enabling dynamic creation of payload In order to enable the dynamic creation of payloads/bodies for PUT and POST RestAPI operations, please set the `EnableDynamicPayload` property of the `OpenApiSkillExecutionParameters` execution parameters to `true` when importing the AI plugin: ```csharp var plugin = await kernel.ImportPluginFunctionsAsync("", new Uri(""), new OpenApiSkillExecutionParameters(httpClient) { EnableDynamicPayload = true }); ``` To dynamically construct a payload for a RestAPI operation that requires payload like this: ```json { "value": "secret-value", "attributes": { "enabled": true } } ``` Please register the following arguments in context variables collection: ```csharp var contextVariables = new ContextVariables(); contextVariables.Set("value", "secret-value"); contextVariables.Set("enabled", true); ``` ### Enabling namespacing To enable namespacing, set the `EnablePayloadNamespacing` property of the `OpenApiSkillExecutionParameters` execution parameters to `true` when importing the AI plugin: ```csharp var plugin = await kernel.ImportPluginFunctionsAsync("", new Uri(""), new OpenApiSkillExecutionParameters(httpClient) { EnablePayloadNamespacing = true }); ``` Remember that the namespacing mechanism depends on prefixing parameter names with their parent parameter name, separated by dots. So, use the 'namespaced' parameter names when adding arguments for them to the context variables. Let's consider this JSON: ```json { "upn": "", "receiver": { "upn": "" }, "cc": { "upn": "" } } ``` It contains `upn` properties at different levels. The the argument registration for the parameters(property values) will look like: ```csharp var contextVariables = new ContextVariables(); contextVariables.Set("upn", ""); contextVariables.Set("receiver.upn", ""); contextVariables.Set("cc.upn", ""); ``` ================================================ FILE: docs/decisions/0007-prompt-extract-template-engine.md ================================================ --- # These are optional elements.

The prompt template is rendered before being send to the AI to allow the prompt to be generated dynamically e.g., include input parameters or the result of a native or semantic function execution. To reduce the complexity and API surface of the Semantic Kernel the prompt template engine is going to be extracted and added to it's own package. The long term goal is to enable the following scenarios: 1. Implement a custom template engine e.g., using Handlebars templates. This is supported now but we want to simplify the API to be implemented. 2. Support using zero or many template engines. ## Decision Drivers * Reduce API surface and complexity of the Semantic Kernel core. * Simplify the `IPromptTemplateEngine` interface to make it easier to implement a custom template engine. * Make the change without breaking existing clients. ## Decision Outcome * Create a new package called `Microsoft.SemanticKernel.TemplateEngine`. * Maintain the existing namespace for all prompt template engine code. * Simplify the `IPromptTemplateEngine` interface to just require implementation of `RenderAsync`. * Dynamically load the existing `PromptTemplateEngine` if the `Microsoft.SemanticKernel.TemplateEngine` assembly is available. ================================================ FILE: docs/decisions/0008-support-generic-llm-request-settings.md ================================================ --- # These are optional elements.

Passing LLM request settings when invoking an AI service 2. Deserialization of LLM requesting settings when loading the `config.json` associated with a Semantic Function The problem with these classes is they include OpenAI specific properties only. A developer can only pass OpenAI specific requesting settings which means: 1. Settings may be passed that have no effect e.g., passing `MaxTokens` to Huggingface 2. Settings that do not overlap with the OpenAI properties cannot be sent e.g., Oobabooga supports additional parameters e.g., `do_sample`, `typical_p`, ... Link to issue raised by the implementer of the Oobabooga AI service: ## Decision Drivers - Semantic Kernel abstractions must be AI Service agnostic i.e., remove OpenAI specific properties. - Solution must continue to support loading Semantic Function configuration (which includes AI request settings) from `config.json`. - Provide good experience for developers e.g., must be able to program with type safety, intellisense, etc. - Provide a good experience for implementors of AI services i.e., should be clear how to define the appropriate AI Request Settings abstraction for the service they are supporting. - Semantic Kernel implementation and sample code should avoid specifying OpenAI specific request settings in code that is intended to be used with multiple AI services. - Semantic Kernel implementation and sample code must be clear if an implementation is intended to be OpenAI specific. ## Considered Options - Use `dynamic` to pass request settings - Use `object` to pass request settings - Define a base class for AI request settings which all implementations must extend Note: Using generics was discounted during an earlier investigation which Dmytro conducted. ## Decision Outcome **Proposed:** Define a base class for AI request settings which all implementations must extend. ## Pros and Cons of the Options ### Use `dynamic` to pass request settings The `IChatCompletion` interface would look like this: ```csharp public interface IChatCompletion : IAIService { ChatHistory CreateNewChat(string? instructions = null); Task> GetChatCompletionsAsync( ChatHistory chat, dynamic? requestSettings = null, CancellationToken cancellationToken = default); IAsyncEnumerable GetStreamingChatCompletionsAsync( ChatHistory chat, dynamic? requestSettings = null, CancellationToken cancellationToken = default); } ``` Developers would have the following options to specify the requesting settings for a semantic function: ```csharp // Option 1: Use an anonymous type await kernel.InvokeSemanticFunctionAsync("Hello AI, what can you do for me?", requestSettings: new { MaxTokens = 256, Temperature = 0.7 }); // Option 2: Use an OpenAI specific class await kernel.InvokeSemanticFunctionAsync(prompt, requestSettings: new OpenAIRequestSettings() { MaxTokens = 256, Temperature = 0.7 }); // Option 3: Load prompt template configuration from a JSON payload string configPayload = @"{ ""schema"": 1, ""description"": ""Say hello to an AI"", ""type"": ""completion"", ""completion"": { ""max_tokens"": 60, ""temperature"": 0.5, ""top_p"": 0.0, ""presence_penalty"": 0.0, ""frequency_penalty"": 0.0 } }"; var templateConfig = JsonSerializer.Deserialize(configPayload); var func = kernel.CreateSemanticFunction(prompt, config: templateConfig!, "HelloAI"); await kernel.RunAsync(func); ``` PR: - Good, SK abstractions contain no references to OpenAI specific request settings - Neutral, because anonymous types can be used which allows a developer to pass in properties that may be supported by multiple AI services e.g., `temperature` or combine properties for different AI services e.g., `max_tokens` (OpenAI) and `max_new_tokens` (Oobabooga). - Bad, because it's not clear to developers what they should pass when creating a semantic function - Bad, because it's not clear to implementors of a chat/text completion service what they should accept or how to add service specific properties. - Bad, there is no compiler type checking for code paths where the dynamic argument has not been resolved which will impact code quality. Type issues manifest as `RuntimeBinderException`'s and may be difficult to troubleshoot. Special care needs to be taken with return types e.g., may be necessary to specify an explicit type rather than just `var` again to avoid errors such as `Microsoft.CSharp.RuntimeBinder.RuntimeBinderException : Cannot apply indexing with [] to an expression of type 'object'` ### Use `object` to pass request settings The `IChatCompletion` interface would look like this: ```csharp public interface IChatCompletion : IAIService { ChatHistory CreateNewChat(string? instructions = null); Task> GetChatCompletionsAsync( ChatHistory chat, object? requestSettings = null, CancellationToken cancellationToken = default); IAsyncEnumerable GetStreamingChatCompletionsAsync( ChatHistory chat, object? requestSettings = null, CancellationToken cancellationToken = default); } ``` The calling pattern is the same as for the `dynamic` case i.e. use either an anonymous type, an AI service specific class e.g., `OpenAIRequestSettings` or load from JSON. PR: - Good, SK abstractions contain no references to OpenAI specific request settings - Neutral, because anonymous types can be used which allows a developer to pass in properties that may be supported by multiple AI services e.g., `temperature` or combine properties for different AI services e.g., `max_tokens` (OpenAI) and `max_new_tokens` (Oobabooga). - Bad, because it's not clear to developers what they should pass when creating a semantic function - Bad, because it's not clear to implementors of a chat/text completion service what they should accept or how to add service specific properties. - Bad, code is needed to perform type checks and explicit casts. The situation is slightly better than for the `dynamic` case. ### Define a base class for AI request settings which all implementations must extend The `IChatCompletion` interface would look like this: ```csharp public interface IChatCompletion : IAIService { ChatHistory CreateNewChat(string? instructions = null); Task> GetChatCompletionsAsync( ChatHistory chat, AIRequestSettings? requestSettings = null, CancellationToken cancellationToken = default); IAsyncEnumerable GetStreamingChatCompletionsAsync( ChatHistory chat, AIRequestSettings? requestSettings = null, CancellationToken cancellationToken = default); } ``` `AIRequestSettings` is defined as follows: ```csharp public class AIRequestSettings { /// /// Service identifier. /// [JsonPropertyName("service_id")] [JsonPropertyOrder(1)] public string? ServiceId { get; set; } = null; /// /// Extra properties /// [JsonExtensionData] public Dictionary? ExtensionData { get; set; } } ``` Developers would have the following options to specify the requesting settings for a semantic function: ```csharp // Option 1: Invoke the semantic function and pass an OpenAI specific instance var result = await kernel.InvokeSemanticFunctionAsync(prompt, requestSettings: new OpenAIRequestSettings() { MaxTokens = 256, Temperature = 0.7 }); Console.WriteLine(result.Result); // Option 2: Load prompt template configuration from a JSON payload string configPayload = @"{ ""schema"": 1, ""description"": ""Say hello to an AI"", ""type"": ""completion"", ""completion"": { ""max_tokens"": 60, ""temperature"": 0.5, ""top_p"": 0.0, ""presence_penalty"": 0.0, ""frequency_penalty"": 0.0 } }"; var templateConfig = JsonSerializer.Deserialize(configPayload); var func = kernel.CreateSemanticFunction(prompt, config: templateConfig!, "HelloAI"); await kernel.RunAsync(func); ``` It would also be possible to use the following pattern: ```csharp this._summarizeConversationFunction = kernel.CreateSemanticFunction( SemanticFunctionConstants.SummarizeConversationDefinition, skillName: nameof(ConversationSummarySkill), description: "Given a section of a conversation, summarize conversation.", requestSettings: new AIRequestSettings() { ExtensionData = new Dictionary() { { "Temperature", 0.1 }, { "TopP", 0.5 }, { "MaxTokens", MaxTokens } } }); ``` The caveat with this pattern is, assuming a more specific implementation of `AIRequestSettings` uses JSON serialization/deserialization to hydrate an instance from the base `AIRequestSettings`, this will only work if all properties are supported by the default JsonConverter e.g., - If we have `MyAIRequestSettings` which includes a `Uri` property. The implementation of `MyAIRequestSettings` would make sure to load a URI converter so that it can serialize/deserialize the settings correctly. - If the settings for `MyAIRequestSettings` are sent to an AI service which relies on the default JsonConverter then a `NotSupportedException` exception will be thrown. PR: - Good, SK abstractions contain no references to OpenAI specific request settings - Good, because it is clear to developers what they should pass when creating a semantic function and it is easy to discover what service specific request setting implementations exist. - Good, because it is clear to implementors of a chat/text completion service what they should accept and how to extend the base abstraction to add service specific properties. - Neutral, because `ExtensionData` can be used which allows a developer to pass in properties that may be supported by multiple AI services e.g., `temperature` or combine properties for different AI services e.g., `max_tokens` (OpenAI) and `max_new_tokens` (Oobabooga). ================================================ FILE: docs/decisions/0009-support-multiple-named-args-in-template-function-calls.md ================================================ --- # These are optional elements.

The purpose of these changes is to add support for calling native functions within semantic functions with multiple named arguments. ## Decision Drivers - Parity with Guidance - Readability - Similarity to languages familiar to SK developers - YAML compatibility ## Considered Options ### Syntax idea 1: Using commas ```handlebars {{Skill.MyFunction street: "123 Main St", zip: "98123", city:"Seattle", age: 25}} ``` Pros: - Commas could make longer function calls easier to read, especially if spaces before and after the arg separator (a colon in this case) are allowed. Cons: - Guidance doesn't use commas - Spaces are already used as delimiters elsewhere so the added complexity of supporting commas isn't necessary ### Syntax idea 2: JavaScript/C#-Style delimiter (colon) ```handlebars {{MyFunction street:"123 Main St" zip:"98123" city:"Seattle" age: "25"}} ``` Pros: - Resembles JavaScript Object syntax and C# named argument syntax Cons: - Doesn't align with Guidance syntax which uses equal signs as arg part delimiters - Too similar to YAML key/value pairs if we support YAML prompts in the future. It's likely possible to support colons as delimiters but would be better to have a separator that is distinct from normal YAML syntax. ### Syntax idea 3: Python/Guidance-Style delimiter ```handlebars {{MyFunction street="123 Main St" zip="98123" city="Seattle"}} ``` Pros: - Resembles Python's keyword argument syntax - Resembles Guidance's named argument syntax - Not too similar to YAML key/value pairs if we support YAML prompts in the future. Cons: - Doesn't align with C# syntax ### Syntax idea 4: Allow whitespace between arg name/value delimiter ```handlebars {{MyFunction street="123 Main St" zip="98123" city="Seattle"}} ``` Pros: - Follows the convention followed by many programming languages of whitespace flexibility where spaces, tabs, and newlines within code don't impact a program's functionality Cons: - Promotes code that is harder to read unless commas can be used (see [Using Commas](#syntax-idea-1-using-commas)) - More complexity to support - Doesn't align with Guidance which doesn't support spaces before and after the = sign. ## Decision Outcome Chosen options: "Syntax idea 3: Python/Guidance-Style keyword arguments", because it aligns well with Guidance's syntax and is the most compatible with YAML and "Syntax idea 4: Allow whitespace between arg name/value delimiter" for more flexible developer experience. Additional decisions: - Continue supporting up to 1 positional argument for backward compatibility. Currently, the argument passed to a function is assumed to be the `$input` context variable. Example ```handlebars {{MyFunction "inputVal" street="123 Main St" zip="98123" city="Seattle"}} ``` - Allow arg values to be defined as strings or variables ONLY, e.g. ```handlebars {{MyFunction street=$street zip="98123" city="Seattle"}} ``` If function expects a value other than a string for an argument, the SDK will use the corresponding TypeConverter to parse the string provided when evaluating the expression. ================================================ FILE: docs/decisions/0010-dotnet-project-structure.md ================================================ --- # These are optional elements.

It is consistent with other e.g., [azure-sdk-for-net](https://github.com/Azure/azure-sdk-for-net) Main categories for the projects will be: 1. `Connectors`: **_A connector project allows the Semantic Kernel to connect to AI and Memory services_**. Some of the existing connector projects may move to other repositories. 1. `Planners`: **_A planner project provides one or more planner implementations which take an ask and convert it into an executable plan to achieve that ask_**. This category will include the current action, sequential and stepwise planners (these could be merged into a single project). Additional planning implementations e.g., planners that generate Powershell or Python code can be added as separate projects. 1. `Functions`: **_A function project that enables the Semantic Kernel to access the functions it will orchestrate_**. This category will include: 1. Semantic functions i.e., prompts executed against an LLM 1. GRPC remote procedures i.e., procedures executed remotely using the GRPC framework 1. Open API endpoints i.e., REST endpoints that have Open API definitions executed remotely using the HTTP protocol 1. `Plugins`: **_A plugin project contains the implementation(s) of a Semantic Kernel plugin_**. A Semantic Kernel plugin is contains a concrete implementation of a function e.g., a plugin may include code for basic text operations. ### Option #1: New `planning`, `functions` and `plugins` project areas ```text SK-dotnet ├── samples/ └── src/ ├── connectors/ │ ├── Connectors.AI.OpenAI* │ ├── Connectors.AI.HuggingFace │ ├── Connectors.Memory.AzureCognitiveSearch │ ├── Connectors.Memory.Qdrant │ ├── ... │ └── Connectors.UnitTests ├── planners/ │ ├── Planners.Action* │ ├── Planners.Sequential* │ └── Planners.Stepwise* ├── functions/ │ ├── Functions.Native* │ ├── Functions.Semantic* │ ├── Functions.Planning* │ ├── Functions.Grpc │ ├── Functions.OpenAPI │ └── Functions.UnitTests ├── plugins/ │ ├── Plugins.Core* │ ├── Plugins.Document │ ├── Plugins.MsGraph │ ├── Plugins.WebSearch │ └── Plugins.UnitTests ├── InternalUtilities/ ├── IntegrationTests ├── SemanticKernel* ├── SemanticKernel.Abstractions* ├── SemanticKernel.MetaPackage └── SemanticKernel.UnitTests ``` ### Changes | Project | Description | | -------------------- | ---------------------------------------------------------------------------------------------------------- | | `Functions.Native` | Extract native functions from Semantic Kernel core and abstractions. | | `Functions.Semantic` | Extract semantic functions from Semantic Kernel core and abstractions.

Feel free to remove any of them. status: accepted contact: dmytrostruk date: 2023-09-21 deciders: shawncal, dmytrostruk consulted: informed: --- # Replace SKContext as Function/Kernel result type with FunctionResult and KernelResult models ## Context and Problem Statement Methods `function.InvokeAsync` and `kernel.RunAsync` return `SKContext` as result type. This has several problems: 1. `SKContext` contains property `Result`, which is `string`. Based on that, it's not possible to return complex type or implement streaming capability in Kernel. 2. `SKContext` contains property `ModelResults`, which is coupled to LLM-specific logic, so it's only applicable to semantic functions in specific cases. 3. `SKContext` as a mechanism of passing information between functions in pipeline should be internal implementation. Caller of Kernel should provide input/request and receive some result, but not `SKContext`. 4. `SKContext` contains information related to the last executed function without a way to access information about specific function in pipeline. ## Decision Drivers 1. Kernel should be able to return complex type as well as support streaming capability. 2. Kernel should be able to return data related to function execution (e.g. amount of tokens used) in a way, when it's not coupled to AI logic. 3. `SKContext` should work as internal mechanism of passing information between functions. 4. There should be a way how to differentiate function result from kernel result, since these entities are different by nature and may contain different set of properties in the future. 5. The possibility to access specific function result in the middle of pipeline will provide more insights to the users how their functions performed. ## Considered Options 1. Use `dynamic` as return type - this option provides some flexibility, but on the other hand removes strong typing, which is preferred option in .NET world. Also, there will be no way how to differentiate function result from Kernel result. 2. Define new types - `FunctionResult` and `KernelResult` - chosen approach. ## Decision Outcome New `FunctionResult` and `KernelResult` return types should cover scenarios like returning complex types from functions, supporting streaming and possibility to access result of each function separately. ### Complex Types and Streaming For complex types and streaming, property `object Value` will be defined in `FunctionResult` to store single function result, and in `KernelResult` to store result from last function in execution pipeline. For better usability, generic method `GetValue` will allow to cast `object Value` to specific type. Examples: ```csharp // string var text = (await kernel.RunAsync(function)).GetValue(); // complex type var myComplexType = (await kernel.RunAsync(function)).GetValue(); // streaming var results = (await kernel.RunAsync(function)).GetValue>(); await foreach (var result in results) { Console.WriteLine(result); } ``` When `FunctionResult`/`KernelResult` will store `TypeA` and caller will try to cast it to `TypeB` - in this case `InvalidCastException` will be thrown with details about types. This will provide some information to the caller which type should be used for casting. ### Metadata To return additional information related to function execution - property `Dictionary Metadata` will be added to `FunctionResult`. This will allow to pass any kind of information to the caller, which should provide some insights how function performed (e.g. amount of tokens used, AI model response etc.) Examples: ```csharp var functionResult = await function.InvokeAsync(context); Console.WriteLine(functionResult.Metadata["MyInfo"]); ``` ### Multiple function results `KernelResult` will contain collection of function results - `IReadOnlyCollection FunctionResults`. This will allow to get specific function result from `KernelResult`. Properties `FunctionName` and `PluginName` in `FunctionResult` will help to get specific function from collection. Example: ```csharp var kernelResult = await kernel.RunAsync(function1, function2, function3); var functionResult2 = kernelResult.FunctionResults.First(l => l.FunctionName == "Function2" && l.PluginName == "MyPlugin"); Assert.Equal("Result2", functionResult2.GetValue()); ``` ================================================ FILE: docs/decisions/0012-kernel-service-registration.md ================================================ --- # These are optional elements.

For example, there is `TextMemoryPlugin`, which supports functions like `retrieve`, `recall`, `save`, `remove`. Constructor is implemented in following way: ```csharp public TextMemoryPlugin(ISemanticTextMemory memory) { this._memory = memory; } ``` `TextMemoryPlugin` depends on `ISemanticTextMemory` interface. In similar way, other Plugins may have multiple dependencies and there should be a way how to resolve required dependencies manually or automatically. At the moment, `ISemanticTextMemory` is a property of `IKernel` interface, which allows to inject `ISemanticTextMemory` into `TextMemoryPlugin` during Plugin initialization: ```csharp kernel.ImportFunctions(new TextMemoryPlugin(kernel.Memory)); ``` There should be a way how to support not only Memory-related interface, but any kind of service, which can be used in Plugin - `ISemanticTextMemory`, `IPromptTemplateEngine`, `IDelegatingHandlerFactory` or any other service. ## Considered Options ### Solution #1.1 (available by default) User is responsible for all Plugins initialization and dependency resolution with **manual** approach. ```csharp var memoryStore = new VolatileMemoryStore(); var embeddingGeneration = new OpenAITextEmbeddingGeneration(modelId, apiKey); var semanticTextMemory = new SemanticTextMemory(memoryStore, embeddingGeneration); var memoryPlugin = new TextMemoryPlugin(semanticTextMemory); var kernel = Kernel.Builder.Build(); kernel.ImportFunctions(memoryPlugin); ``` Note: this is native .NET approach how to resolve service dependencies manually, and this approach should always be available by default. Any other solutions which could help to improve dependency resolution can be added on top of this approach. ### Solution #1.2 (available by default) User is responsible for all Plugins initialization and dependency resolution with **dependency injection** approach. ```csharp var serviceCollection = new ServiceCollection(); serviceCollection.AddTransient(); serviceCollection.AddTransient( (serviceProvider) => new OpenAITextEmbeddingGeneration(modelId, apiKey)); serviceCollection.AddTransient(); var services = serviceCollection.BuildServiceProvider(); // In theory, TextMemoryPlugin can be also registered in DI container. var memoryPlugin = new TextMemoryPlugin(services.GetService()); var kernel = Kernel.Builder.Build(); kernel.ImportFunctions(memoryPlugin); ``` Note: in similar way as Solution #1.1, this way should be supported out of the box. Users always can handle all the dependencies on their side and just provide required Plugins to Kernel. ### Solution #2.1 Custom service collection and service provider on Kernel level to simplify dependency resolution process, as addition to Solution #1.1 and Solution #1.2. Interface `IKernel` will have its own service provider `KernelServiceProvider` with minimal functionality to get required service. ```csharp public interface IKernelServiceProvider { T? GetService(string? name = null); } public interface IKernel { IKernelServiceProvider Services { get; } } ``` ```csharp var kernel = Kernel.Builder .WithLoggerFactory(ConsoleLogger.LoggerFactory) .WithOpenAITextEmbeddingGenerationService(modelId, apiKey) .WithService(), .WithService() .Build(); var semanticTextMemory = kernel.Services.GetService(); var memoryPlugin = new TextMemoryPlugin(semanticTextMemory); kernel.ImportFunctions(memoryPlugin); ``` Pros: - No dependency on specific DI container library. - Lightweight implementation. - Possibility to register only those services that can be used by Plugins (isolation from host application). - Possibility to register same interface multiple times by **name**. Cons: - Implementation and maintenance for custom DI container, instead of using already existing libraries. - To import Plugin, it still needs to be initialized manually to inject specific service. ### Solution #2.2 This solution is an improvement for last disadvantage of Solution #2.1 to handle case, when Plugin instance should be initialized manually. This will require to add new way how to import Plugin into Kernel - not with object **instance**, but with object **type**. In this case, Kernel will be responsible for `TextMemoryPlugin` initialization and injection of all required dependencies from custom service collection. ```csharp // Instead of this var semanticTextMemory = kernel.Services.GetService(); var memoryPlugin = new TextMemoryPlugin(semanticTextMemory); kernel.ImportFunctions(memoryPlugin); // Use this kernel.ImportFunctions(); ``` ### Solution #3 Instead of custom service collection and service provider in Kernel, use already existing DI library - `Microsoft.Extensions.DependencyInjection`. ```csharp var serviceCollection = new ServiceCollection(); serviceCollection.AddTransient(); serviceCollection.AddTransient( (serviceProvider) => new OpenAITextEmbeddingGeneration(modelId, apiKey)); serviceCollection.AddTransient(); var services = serviceCollection.BuildServiceProvider(); var kernel = Kernel.Builder .WithLoggerFactory(ConsoleLogger.LoggerFactory) .WithOpenAITextEmbeddingGenerationService(modelId, apiKey) .WithServices(services) // Pass all registered services from host application to Kernel .Build(); // Plugin Import - option #1 var semanticTextMemory = kernel.Services.GetService(); var memoryPlugin = new TextMemoryPlugin(semanticTextMemory); kernel.ImportFunctions(memoryPlugin); // Plugin Import - option #2 kernel.ImportFunctions(); ``` Pros: - No implementation is required for dependency resolution - just use already existing .NET library. - The possibility to inject all registered services at once in already existing applications and use them as Plugin dependencies. Cons: - Additional dependency for Semantic Kernel package - `Microsoft.Extensions.DependencyInjection`. - No possibility to include specific list of services (lack of isolation from host application). - Possibility of `Microsoft.Extensions.DependencyInjection` version mismatch and runtime errors (e.g. users have `Microsoft.Extensions.DependencyInjection` `--version 2.0` while Semantic Kernel uses `--version 6.0`) ## Decision Outcome As for now, support Solution #1.1 and Solution #1.2 only, to keep Kernel as unit of single responsibility. Plugin dependencies should be resolved before passing Plugin instance to the Kernel. ================================================ FILE: docs/decisions/0013-memory-as-plugin.md ================================================ --- # These are optional elements.

This property is needed to inject Memory capabilities in Plugins. At the moment, `ISemanticTextMemory` interface is main dependency of `TextMemoryPlugin`, and in some examples `TextMemoryPlugin` is initialized as `new TextMemoryPlugin(kernel.Memory)`. While this approach works for Memory, there is no way how to inject `MathPlugin` into other Plugin at the moment. Following the same approach and adding `Math` property to `Kernel` type is not scalable solution, as it's not possible to define separate properties for each available Plugin. ## Decision Drivers 1. Memory should not be a property of `Kernel` type if it's not used by the kernel. 2. Memory should be treated in the same way as other plugins or services, that may be required by specific Plugins. 3. There should be a way how to register Memory capability with attached Vector DB and inject that capability in Plugins that require it. ## Decision Outcome Move all Memory-related logic to separate project called `Plugins.Memory`. This will allow to simplify Kernel logic and use Memory in places where it's needed (other Plugins). High-level tasks: 1. Move Memory-related code to separate project. 2. Implement a way how to inject Memory in Plugins that require it. 3. Remove `Memory` property from `Kernel` type. ================================================ FILE: docs/decisions/0014-chat-completion-roles-in-prompt.md ================================================ --- # These are optional elements. Feel free to remove any of them. status: accepted contact: SergeyMenshykh date: 2023-10-23 deciders: markwallace-microsoft, matthewbolanos consulted: informed: --- # SK prompt syntax for chat completion roles ## Context and Problem Statement Today, SK does not have the ability to mark a block of text in a prompt as a message with a specific role, such as assistant, system, or user. As a result, SK can't chunk the prompt into the list of messages required by chat completion connectors. Additionally, prompts can be defined using a range of template syntaxes supported by various template engines, such as Handlebars, Jinja, and others. Each of these syntaxes may represent chat messages or roles in a distinct way. Consequently, the template engine syntax may leak into SK's domain if no proper abstraction is put in place, coupling SK with the template engines and making it impossible to support new ones. ## Decision Drivers - It should be possible to mark a block of text in a prompt as a message with a role so that it can be converted into a list of chat messages for use by chat completion connectors. - The syntax specific to the template engine message/role should be mapped to the SK message/role syntax to abstract SK from a specific template engine syntax. ## Considered Options **1. Message/role tags are generated by functions specified in a prompt.** This option relies on the fact that many template engines can invoke functions specified in the template. Therefore, an internal function can be registered with a template engine, and the function will create a message/model tag based on the provided arguments. The prompt template engine will execute the function and emit the function result into the prompt template, and the rendered prompt will have a section for each message/role decorated with these tags. Here's an example of how this can be done using the SK basic template engine and Handlebars: Function: ```csharp internal class SystemFunctions { public string Message(string role) { return $""; } } ``` Prompt: ```bash {{message role="system"}} You are a bank manager. Be helpful, respectful, appreciate diverse language styles. {{message role="system"}} {{message role="user"}} I want to {{$input}} {{message role="user"}} ``` Rendered prompt: ```xml You are a bank manager. Be helpful, respectful, appreciate diverse language styles. I want to buy a house. ``` **2. Message/role tags are generated by a prompt-specific mechanism.** This option utilizes template engine syntax constructions, helpers, and handlers other than functions to inject SK message/role tags into the final prompt. In the example below, to parse the prompt that uses the handlebars syntax we need to register a block helper (a callback that is invoked when the Handlebars engine encounters it) to emit the SK message/role tags in the resulting prompt. Block helpers: ```csharp this.handlebarsEngine.RegisterHelper("system", (EncodedTextWriter output, Context context, Arguments arguments) => { //Emit the tags }); this.handlebarsEngine.RegisterHelper("user", (EncodedTextWriter output, Context context, Arguments arguments) => { //Emit the tags }); ``` Prompt: ```bash {{#system~}} You are a bank manager. Be helpful, respectful, appreciate diverse language styles. {{~/system}} {{#user~}} I want to {{$input}} {{~/user}} ``` Rendered prompt: ```xml You are a bank manager. Be helpful, respectful, appreciate diverse language styles. I want to buy a house. ``` **3. Message/role tags are applied on top of prompt template engine**. This option presumes specifying the SK message/role tags directly in a prompt to denote message/role blocks in way that template engine does not parse/handle them and considers them as a regular text. In the example below, the prompt the `` tags are marking boundaries of the system and user messages and SK basic template engine consider them as regular text without processing them. Prompt: ```xml You are a bank manager. Be helpful, respectful, appreciate diverse language styles. I want to {{$input}} ``` Rendered prompt: ```xml You are a bank manager. Be helpful, respectful, appreciate diverse language styles. I want to buy a house. ``` ## Pros and Cons **1. Message/role tags are generated by functions specified in a prompt** Pros: - Functions can be defined once and reused in prompt templates that support function calling. Cons: - Functions might not be supported by some template engines. - The system/internal functions should be pre-registered by SK so users don't need to import them. - Each prompt template engine will have how to discover and call the system/internal functions. **2. Message/role tags are generated by prompt specific mechanism** Pros: - Enables message/role representation with the optimal template engine syntax constructions, aligning with other constructions for that specific engine. Cons: - Each prompt template engine will have to register callbacks/handlers to handle template syntax constructions rendering to emit SK message/role tags. **3. Message/role tags are applied on top of prompt template engine** Pros: - No changes are required to prompt template engines. Cons: - The message/role tag syntax may not align with other syntax constructions for that template engine. - Syntax errors in message/role tags will be detected by components parsing the prompt and not by prompt template engines. ## Decision Outcome It was agreed not to limit ourselves to only one possible option because it may not be feasible to apply that option to new template engines we might need to support in the future. Instead, each time a new template engine is added, every option should be considered, and the optimal one should be preferred for that particular template engine. It was also agreed that, at the moment, we will go with the "3. Message/role tags are applied on top of the prompt template engine" option to support the message/role prompt syntax in SK, which currently uses the `BasicPromptTemplateEngine` engine. ================================================ FILE: docs/decisions/0015-completion-service-selection.md ================================================ --- # These are optional elements.

With the addition of a new chat completion prompts and potentially other prompt types, such as image, on the horizon, we need a way to select a completion service type to run these prompts. ## Decision Drivers - Semantic function should be able to identify a completion service type to use when processing text, chat, or image prompts. ## Considered Options **1. Completion service type identified by the "prompt_type" property.** This option presumes adding the 'prompt_type' property to the prompt template config model class, 'PromptTemplateConfig.' The property will be specified once by a prompt developer and will be used by the 'SemanticFunction' class to decide which completion service type (not instance) to use when resolving an instance of that particular completion service type. **Prompt template** ```json { "schema": "1", "description": "Hello AI, what can you do for me?", "prompt_type": "", "models": [...] } ``` **Semantic function pseudocode** ```csharp if(string.IsNullOrEmpty(promptTemplateConfig.PromptType) || promptTemplateConfig.PromptType == "text") { var service = this._serviceSelector.SelectAIService(context.ServiceProvider, this._modelSettings); //render the prompt, call the service, process and return result } else (promptTemplateConfig.PromptType == "chat") { var service = this._serviceSelector.SelectAIService(context.ServiceProvider, this._modelSettings); //render the prompt, call the service, process and return result }, else (promptTemplateConfig.PromptType == "image") { var service = this._serviceSelector.SelectAIService(context.ServiceProvider, this._modelSettings); //render the prompt, call the service, process and return result } ``` **Example** ```json name: ComicStrip.Create prompt: "Generate ideas for a comic strip based on {{$input}}. Design characters, develop the plot, ..." config: { "schema": 1, "prompt_type": "text", ... } name: ComicStrip.Draw prompt: "Draw the comic strip - {{$comicStrip.Create $input}}" config: { "schema": 1, "prompt_type": "image", ... } ``` Pros: - Deterministically specifies which completion service **type** to use, so image prompts won't be rendered by a text completion service, and vice versa. Cons: - Another property to specify by a prompt developer. **2. Completion service type identified by prompt content.** The idea behind this option is to analyze the rendered prompt by using regex to check for the presence of specific markers associated with the prompt type. For example, the presence of the `` tag in the rendered prompt might indicate that the prompt is a chat prompt and should be handled by the chat completion service. This approach may work reliably when we have two completion service types - text and chat - since the logic would be straightforward: if the message tag is found in the rendered prompt, handle it with the chat completion service; otherwise, use the text completion service. However, this logic becomes unreliable when we start adding new prompt types, and those prompts lack markers specific to their prompt type. For example, if we add an image prompt, we won't be able to distinguish between a text prompt and an image prompt unless the image prompt has a unique marker identifying it as such. ```csharp if (Regex.IsMatch(renderedPrompt, @".*?")) { var service = this._serviceSelector.SelectAIService(context.ServiceProvider, this._modelSettings); //render the prompt, call the service, process and return result }, else { var service = this._serviceSelector.SelectAIService(context.ServiceProvider, this._modelSettings); //render the prompt, call the service, process and return result } ``` **Example** ```json name: ComicStrip.Create prompt: "Generate ideas for a comic strip based on {{$input}}. Design characters, develop the plot, ..." config: { "schema": 1, ... } name: ComicStrip.Draw prompt: "Draw the comic strip - {{$comicStrip.Create $input}}" config: { "schema": 1, ... } ``` Pros: - No need for a new property to identify the prompt type. Cons: - Unreliable unless the prompt contains unique markers specifically identifying the prompt type. ## Decision Outcome We decided to choose the '2. Completion service type identified by prompt content' option and will reconsider it when we encounter another completion service type that cannot be supported by this option or when we have a solid set of requirements for using a different mechanism for selecting the completion service type. ================================================ FILE: docs/decisions/0016-custom-prompt-template-formats.md ================================================ --- status: approved contact: markwallace-microsoft date: 2023-10-26 deciders: matthewbolanos, markwallace-microsoft, SergeyMenshykh, RogerBarreto consulted: dmytrostruk informed: --- # Custom Prompt Template Formats ## Context and Problem Statement Semantic Kernel currently supports a custom prompt template language that allows for variable interpolation and function execution. Semantic Kernel allows for custom prompt template formats to be integrated e.g., prompt templates using [Handlebars](https://handlebarsjs.com/) syntax. The purpose of this ADR is to describe how a custom prompt template formats will be supported in the Semantic Kernel. ### Current Design By default the `Kernel` uses the `BasicPromptTemplateEngine` which supports the Semantic Kernel specific template format. #### Code Patterns Below is an expanded example of how to create a semantic function from a prompt template string which uses the built-in Semantic Kernel format: ```csharp IKernel kernel = Kernel.Builder .WithPromptTemplateEngine(new BasicPromptTemplateEngine()) .WithOpenAIChatCompletionService( modelId: openAIModelId, apiKey: openAIApiKey) .Build(); kernel.ImportFunctions(new TimePlugin(), "time"); string templateString = "Today is: {{time.Date}} Is it weekend time (weekend/not weekend)?"; var promptTemplateConfig = new PromptTemplateConfig(); var promptTemplate = new PromptTemplate(templateString, promptTemplateConfig, kernel.PromptTemplateEngine); var kindOfDay = kernel.RegisterSemanticFunction("KindOfDay", promptTemplateConfig, promptTemplate); var result = await kernel.RunAsync(kindOfDay); Console.WriteLine(result.GetValue()); ``` We have an extension method `var kindOfDay = kernel.CreateSemanticFunction(promptTemplate);` to simplify the process to create and register a semantic function but the expanded format is shown above to highlight the dependency on `kernel.PromptTemplateEngine`. Also the `BasicPromptTemplateEngine` is the default prompt template engine and will be loaded automatically if the package is available and not other prompt template engine is specified. Some issues with this: 1. `Kernel` only supports a single `IPromptTemplateEngine` so we cannot support using multiple prompt templates at the same time. 1. `IPromptTemplateEngine` is stateless and must perform a parse of the template for each render 1. Our semantic function extension methods relay on our implementation of `IPromptTemplate` (i.e., `PromptTemplate`) which stores the template string and uses the `IPromptTemplateEngine` to render it every time. Note implementations of `IPromptTemplate` are currently stateful as they also store the parameters. #### Performance The `BasicPromptTemplateEngine` uses the `TemplateTokenizer` to parse the template i.e. extract the blocks. Then it renders the template i.e. inserts variables and executes functions. Some sample timings for these operations: | Operation | Ticks | Milliseconds | | ---------------- | ------- | ------------ | | Extract blocks | 1044427 | 103 | | Render variables | 168 | 0 | Sample template used was: `"{{variable1}} {{variable2}} {{variable3}} {{variable4}} {{variable5}}"` **Note: We will use the sample implementation to support the f-string template format.** Using `HandlebarsDotNet` for the same use case results in the following timings: | Operation | Ticks | Milliseconds | | ---------------- | ----- | ------------ | | Compile template | 66277 | 6 | | Render variables | 4173 | 0 | **By separating the extract blocks/compile from the render variables operation it will be possible to optimise performance by compiling templates just once.** #### Implementing a Custom Prompt Template Engine There are two interfaces provided: ```csharp public interface IPromptTemplateEngine { Task RenderAsync(string templateText, SKContext context, CancellationToken cancellationToken = default); } public interface IPromptTemplate { IReadOnlyList Parameters { get; } public Task RenderAsync(SKContext executionContext, CancellationToken cancellationToken = default); } ``` A prototype implementation of a handlebars prompt template engine could look something like this: ```csharp public class HandlebarsTemplateEngine : IPromptTemplateEngine { private readonly ILoggerFactory _loggerFactory; public HandlebarsTemplateEngine(ILoggerFactory? loggerFactory = null) { this._loggerFactory = loggerFactory ?? NullLoggerFactory.Instance; } public async Task RenderAsync(string templateText, SKContext context, CancellationToken cancellationToken = default) { var handlebars = HandlebarsDotNet.Handlebars.Create(); var functionViews = context.Functions.GetFunctionViews(); foreach (FunctionView functionView in functionViews) { var skfunction = context.Functions.GetFunction(functionView.PluginName, functionView.Name); handlebars.RegisterHelper($"{functionView.PluginName}_{functionView.Name}", async (writer, hcontext, parameters) => { var result = await skfunction.InvokeAsync(context).ConfigureAwait(true); writer.WriteSafeString(result.GetValue()); }); } var template = handlebars.Compile(templateText); var prompt = template(context.Variables); return await Task.FromResult(prompt).ConfigureAwait(true); } } ``` **Note: This is just a prototype implementation for illustration purposes only.** Some issues: 1. The `IPromptTemplate` interface is not used and causes confusion. 1. There is no way to allow developers to support multiple prompt template formats at the same time. There is one implementation of `IPromptTemplate` provided in the Semantic Kernel core package. The `RenderAsync` implementation just delegates to the `IPromptTemplateEngine`. The `Parameters` list get's populated with the parameters defined in the `PromptTemplateConfig` and any missing variables defined in the template. #### Handlebars Considerations Handlebars does not support dynamic binding of helpers. Consider the following snippet: ```csharp HandlebarsHelper link_to = (writer, context, parameters) => { writer.WriteSafeString($"{context["text"]}"); }; string source = @"Click here: {{link_to}}"; var data = new { url = "https://github.com/rexm/handlebars.net", text = "Handlebars.Net" }; // Act var handlebars = HandlebarsDotNet.Handlebars.Create(); handlebars.RegisterHelper("link_to", link_to); var template = handlebars1.Compile(source); // handlebars.RegisterHelper("link_to", link_to); This also works var result = template1(data); ``` Handlebars allows the helpers to be registered with the `Handlebars` instance either before or after a template is compiled. The optimum would be to have a shared `Handlebars` instance for a specific collection of functions and register the helpers just once. For use cases where the Kernel function collection may have been mutated we will be forced to create a `Handlebars` instance at render time and then register the helpers. This means we cannot take advantage of the performance improvement provided by compiling the template. ## Decision Drivers In no particular order: - Support creating a semantic function without a `IKernel`instance. - Support late binding of functions i.e., having functions resolved when the prompt is rendered. - Support allowing the prompt template to be parsed (compiled) just once to optimize performance if needed. - Support using multiple prompt template formats with a single `Kernel` instance. - Provide simple abstractions which allow third parties to implement support for custom prompt template formats. ## Considered Options - Obsolete `IPromptTemplateEngine` and replace with `IPromptTemplateFactory`. - ### Obsolete `IPromptTemplateEngine` and replace with `IPromptTemplateFactory` ISKFunction class relationships Below is an expanded example of how to create a semantic function from a prompt template string which uses the built-in Semantic Kernel format: ```csharp // Semantic function can be created once var promptTemplateFactory = new BasicPromptTemplateFactory(); string templateString = "Today is: {{time.Date}} Is it weekend time (weekend/not weekend)?"; var promptTemplateConfig = new PromptTemplateConfig(); // Line below will replace the commented out code var promptTemplate = promptTemplateFactory.CreatePromptTemplate(templateString, promptTemplateConfig); var kindOfDay = ISKFunction.CreateSemanticFunction("KindOfDay", promptTemplateConfig, promptTemplate) // var promptTemplate = new PromptTemplate(promptTemplate, promptTemplateConfig, kernel.PromptTemplateEngine); // var kindOfDay = kernel.RegisterSemanticFunction("KindOfDay", promptTemplateConfig, promptTemplate); // Create Kernel after creating the semantic function // Later we will support passing a function collection to the KernelBuilder IKernel kernel = Kernel.Builder .WithOpenAIChatCompletionService( modelId: openAIModelId, apiKey: openAIApiKey) .Build(); kernel.ImportFunctions(new TimePlugin(), "time"); // Optionally register the semantic function with the Kernel kernel.RegisterCustomFunction(kindOfDay); var result = await kernel.RunAsync(kindOfDay); Console.WriteLine(result.GetValue()); ``` **Notes:** - `BasicPromptTemplateFactory` will be the default implementation and will be automatically provided in `KernelSemanticFunctionExtensions`. Developers will also be able to provide their own implementation. - The factory uses the new `PromptTemplateConfig.TemplateFormat` to create the appropriate `IPromptTemplate` instance. - We should look to remove `promptTemplateConfig` as a parameter to `CreateSemanticFunction`. That change is outside of the scope of this ADR. The `BasicPromptTemplateFactory` and `BasicPromptTemplate` implementations look as follows: ```csharp public sealed class BasicPromptTemplateFactory : IPromptTemplateFactory { private readonly IPromptTemplateFactory _promptTemplateFactory; private readonly ILoggerFactory _loggerFactory; public BasicPromptTemplateFactory(IPromptTemplateFactory promptTemplateFactory, ILoggerFactory? loggerFactory = null) { this._promptTemplateFactory = promptTemplateFactory; this._loggerFactory = loggerFactory ?? NullLoggerFactory.Instance; } public IPromptTemplate? CreatePromptTemplate(string templateString, PromptTemplateConfig promptTemplateConfig) { if (promptTemplateConfig.TemplateFormat.Equals(PromptTemplateConfig.SEMANTICKERNEL, System.StringComparison.Ordinal)) { return new BasicPromptTemplate(templateString, promptTemplateConfig, this._loggerFactory); } else if (this._promptTemplateFactory is not null) { return this._promptTemplateFactory.CreatePromptTemplate(templateString, promptTemplateConfig); } throw new SKException($"Invalid prompt template format {promptTemplateConfig.TemplateFormat}"); } } public sealed class BasicPromptTemplate : IPromptTemplate { public BasicPromptTemplate(string templateString, PromptTemplateConfig promptTemplateConfig, ILoggerFactory? loggerFactory = null) { this._loggerFactory = loggerFactory ?? NullLoggerFactory.Instance; this._logger = this._loggerFactory.CreateLogger(typeof(BasicPromptTemplate)); this._templateString = templateString; this._promptTemplateConfig = promptTemplateConfig; this._parameters = new(() => this.InitParameters()); this._blocks = new(() => this.ExtractBlocks(this._templateString)); this._tokenizer = new TemplateTokenizer(this._loggerFactory); } public IReadOnlyList Parameters => this._parameters.Value; public async Task RenderAsync(SKContext executionContext, CancellationToken cancellationToken = default) { return await this.RenderAsync(this._blocks.Value, executionContext, cancellationToken).ConfigureAwait(false); } // Not showing the implementation details } ``` **Note:** - The call to `ExtractBlocks` is called lazily once for each prompt template - The `RenderAsync` doesn't need to extract the blocks every time ## Decision Outcome Chosen option: "Obsolete `IPromptTemplateEngine` and replace with `IPromptTemplateFactory`", because addresses the requirements and provides good flexibility for the future. ================================================ FILE: docs/decisions/0017-openai-function-calling.md ================================================ --- status: accepted contact: gitri-ms date: 2023-09-21 deciders: gitri-ms, shawncal consulted: lemillermicrosoft, awharrison-28, dmytrostruk, nacharya1 informed: eavanvalkenburg, kevdome3000 --- # OpenAI Function Calling Support ## Context and Problem Statement The [function calling](https://platform.openai.com/docs/guides/gpt/function-calling) capability of OpenAI's Chat Completions API allows developers to describe functions to the model, and have the model decide whether to output a JSON object specifying a function and appropriate arguments to call in response to the given prompt. This capability is enabled by two new API parameters to the `/v1/chat/completions` endpoint: - `function_call` - auto (default), none, or a specific function to call - `functions` - JSON descriptions of the functions available to the model Functions provided to the model are injected as part of the system message and are billed/counted as input tokens. We have received several community requests to provide support for this capability when using SK with the OpenAI chat completion models that support it. ## Decision Drivers - Minimize changes to the core kernel for OpenAI-specific functionality - Cost concerns with including a long list of function descriptions in the request - Security and cost concerns with automatically executing functions returned by the model ## Considered Options - Support sending/receiving functions via chat completions endpoint _with_ modifications to interfaces - Support sending/receiving functions via chat completions endpoint _without_ modifications to interfaces - Implement a planner around the function calling capability ## Decision Outcome Chosen option: "Support sending/receiving functions via chat completions endpoint _without_ modifications to interfaces" With this option, we utilize the existing request settings object to send functions to the model. The app developer controls what functions are included and is responsible for validating and executing the function result. ### Consequences - Good, because avoids breaking changes to the core kernel - Good, because OpenAI-specific functionality is contained to the OpenAI connector package - Good, because allows app to control what functions are available to the model (including non-SK functions) - Good, because keeps the option open for integrating with planners in the future - Neutral, because requires app developer to validate and execute resulting function - Bad, because not as obvious how to use this capability and access the function results ## Pros and Cons of the Options ### Support sending/receiving functions _with_ modifications to chat completions interfaces This option would update the `IChatCompletion` and `IChatResult` interfaces to expose parameters/methods for providing and accessing function information. - Good, because provides a clear path for using the function calling capability - Good, because allows app to control what functions are available to the model (including non-SK functions) - Neutral, because requires app developer to validate and execute resulting function - Bad, because introduces breaking changes to core kernel abstractions - Bad, because OpenAI-specific functionality would be included in core kernel abstractions and would need to be ignored by other model providers ### Implement a planner around the function calling capability Orchestrating external function calls fits within SK's concept of planning. With this approach, we would implement a planner that would take the function calling result and produce a plan that the app developer could execute (similar to SK's ActionPlanner). - Good, because producing a plan result makes it easy for the app developer to execute the chosen function - Bad, because functions would need to be registered with the kernel in order to be executed - Bad, because would create confusion about when to use which planner ## Additional notes There has been much discussion and debate over the pros and cons of automatically invoking a function returned by the OpenAI model, if it is registered with the kernel. As there are still many open questions around this behavior and its implications, we have decided to not include this capability in the initial implementation. We will continue to explore this option and may include it in a future update. ================================================ FILE: docs/decisions/0018-kernel-hooks-phase2.md ================================================ ## Context and Problem Statement Currently Kernel invoking and invoked handlers don't expose the prompt to the handlers. The proposal is a way to expose the prompt to the handlers. - Pre-Execution / Invoking - Get: Prompt generated by the current `SemanticFunction.TemplateEngine` before calling the LLM - Set: Modify a prompt content before sending it to LLM - Post-Execution / Invoked - Get: Generated Prompt ## Decision Drivers - Prompt template should be generated just once per function execution within the Kernel.RunAsync execution. - Handlers should be able to see and modify the prompt before the LLM execution. - Handlers should be able to see prompt after the LLM execution. - Calling Kernel.RunAsync(function) or ISKFunction.InvokeAsync(kernel) should trigger the events. ## Out of Scope - Skip plan steps using Pre-Hooks. - Get the used services (Template Engine, IAIServices, etc) in the Pre/Post Hooks. - Get the request settings in the Pre/Post Hooks. ## Current State of Kernel for Pre/Post Hooks Current state of Kernel: ```csharp class Kernel : IKernel RunAsync() { var context = this.CreateNewContext(variables); var functionDetails = skFunction.Describe(); var functionInvokingArgs = this.OnFunctionInvoking(functionDetails, context); functionResult = await skFunction.InvokeAsync(context, cancellationToken: cancellationToken); var functionInvokedArgs = this.OnFunctionInvoked(functionDetails, functionResult); } ``` ## Developer Experience Below is the expected end user experience when coding using Pre/Post Hooks to get or modify prompts. ```csharp const string FunctionPrompt = "Write a random paragraph about: {{$input}}."; var excuseFunction = kernel.CreateSemanticFunction(...); void MyPreHandler(object? sender, FunctionInvokingEventArgs e) { Console.WriteLine($"{e.FunctionView.PluginName}.{e.FunctionView.Name} : Pre Execution Handler - Triggered"); // Will be false for non semantic functions if (e.TryGetRenderedPrompt(out var prompt)) { Console.WriteLine("Rendered Prompt:"); Console.WriteLine(prompt); // Update the prompt if needed e.TryUpdateRenderedPrompt("Write a random paragraph about: Overriding a prompt"); } } void MyPostHandler(object? sender, FunctionInvokedEventArgs e) { Console.WriteLine($"{e.FunctionView.PluginName}.{e.FunctionView.Name} : Post Execution Handler - Triggered"); // Will be false for non semantic functions if (e.TryGetRenderedPrompt(out var prompt)) { Console.WriteLine("Used Prompt:"); Console.WriteLine(prompt); } } kernel.FunctionInvoking += MyPreHandler; kernel.FunctionInvoked += MyPostHandler; const string Input = "I missed the F1 final race"; var result = await kernel.RunAsync(Input, excuseFunction); Console.WriteLine($"Function Result: {result.GetValue()}"); ``` Expected output: ``` MyPlugin.MyFunction : Pre Execution Handler - Triggered Rendered Prompt: Write a random paragraph about: I missed the F1 final race. MyPlugin.MyFunction : Post Execution Handler - Triggered Used Prompt: Write a random paragraph about: Overriding a prompt FunctionResult: ``` ## Considered Options ### Improvements Common to all options Move `Dictionary` property `Metadata` from `FunctionInvokedEventArgs` to `SKEventArgs` abstract class. Pro: - This will make all SKEventArgs extensible, allowing extra information to be passed to the EventArgs when `specialization` isn't possible. ### Option 1: Kernel awareness of SemanticFunctions ```csharp class Kernel : IKernel RunAsync() { if (skFunction is SemanticFunction semanticFunction) { var prompt = await semanticFunction.TemplateEngine.RenderAsync(semanticFunction.Template, context); var functionInvokingArgs = this.OnFunctionInvoking(functionDetails, context, prompt); // InvokeWithPromptAsync internal functionResult = await semanticFunction.InternalInvokeWithPromptAsync(prompt, context, cancellationToken: cancellationToken); } else { functionResult = await skFunction.InvokeAsync(context, cancellationToken: cancellationToken); } } class SemanticFunction : ISKFunction public InvokeAsync(context, cancellationToken) { var prompt = _templateEngine.RenderAsync(); return InternalInvokeWithPromptAsync(prompt, context, cancellationToken); } internal InternalInvokeWithPromptAsync(string prompt) { ... current logic to call LLM } ``` ### Pros and Cons Pros: - Simpler and quicker to implement - Small number of changes limited mostly to `Kernel` and `SemanticFunction` classes Cons: - `Kernel` is aware of `SemanticFunction` implementation details - Not extensible to show prompts of custom `ISKFunctions` implementations ### Option 2: Delegate to the ISKFunction how to handle events (Interfaces approach) ```csharp class Kernel : IKernel { RunAsync() { var functionInvokingArgs = await this.TriggerEvent(this.FunctionInvoking, skFunction, context); var functionResult = await skFunction.InvokeAsync(context, cancellationToken: cancellationToken); var functionInvokedArgs = await this.TriggerEvent( this.FunctionInvoked, skFunction, context); } private TEventArgs? TriggerEvent(EventHandler? eventHandler, ISKFunction function, SKContext context) where TEventArgs : SKEventArgs { if (eventHandler is null) { return null; } if (function is ISKFunctionEventSupport supportedFunction) { var eventArgs = await supportedFunction.PrepareEventArgsAsync(context); eventHandler.Invoke(this, eventArgs); return eventArgs; } // Think about allowing to add data with the extra interface. // If a function don't support the specific event we can: return null; // Ignore or Throw. throw new NotSupportedException($"The provided function \"{function.Name}\" does not supports and implements ISKFunctionHandles<{typeof(TEventArgs).Name}>"); } } public interface ISKFunctionEventSupport where TEventArgs : SKEventArgs { Task PrepareEventArgsAsync(SKContext context, TEventArgs? eventArgs = null); } class SemanticFunction : ISKFunction, ISKFunctionEventSupport, ISKFunctionEventSupport { public FunctionInvokingEventArgs PrepareEventArgsAsync(SKContext context, FunctionInvokingEventArgs? eventArgs = null) { var renderedPrompt = await this.RenderPromptTemplateAsync(context); context.Variables.Set(SemanticFunction.RenderedPromptKey, renderedPrompt); return new SemanticFunctionInvokingEventArgs(this.Describe(), context); // OR Metadata Dictionary return new FunctionInvokingEventArgs(this.Describe(), context, new Dictionary() { { RenderedPrompt, renderedPrompt } }); } public FunctionInvokedEventArgs PrepareEventArgsAsync(SKContext context, FunctionInvokedEventArgs? eventArgs = null) { return Task.FromResult(new SemanticFunctionInvokedEventArgs(this.Describe(), context)); } } public sealed class SemanticFunctionInvokedEventArgs : FunctionInvokedEventArgs { public SemanticFunctionInvokedEventArgs(FunctionDescription functionDescription, SKContext context) : base(functionDescription, context) { _context = context; Metadata[RenderedPromptKey] = this._context.Variables[RenderedPromptKey]; } public string? RenderedPrompt => this.Metadata[RenderedPromptKey]; } public sealed class SemanticFunctionInvokingEventArgs : FunctionInvokingEventArgs { public SemanticFunctionInvokingEventArgs(FunctionDescription functionDescription, SKContext context) : base(functionDescription, context) { _context = context; } public string? RenderedPrompt => this._context.Variables[RenderedPromptKey]; } ``` ### Pros and Cons Pros: - `Kernel` is not aware of `SemanticFunction` implementation details or any other `ISKFunction` implementation - Extensible to show dedicated EventArgs per custom `ISKFunctions` implementation, including prompts for semantic functions - Extensible to support future events on the Kernel thru the `ISKFunctionEventSupport` interface - Functions can have their own EventArgs specialization. - Interface is optional, so custom `ISKFunctions` can choose to implement it or not Cons: - Any custom functions now will have to responsibility implement the `ISKFunctionEventSupport` interface if they want to support events. - Handling events in another `ISKFunction` requires more complex approaches to manage the context and the prompt + any other data in different event handling methods. ### Option 3: Delegate to the ISKFunction how to handle events (InvokeAsync Delegates approach) Add Kernel event handler delegate wrappers to `ISKFunction.InvokeAsync` interface. This approach shares the responsibility of handling the events between the `Kernel` and the `ISKFunction` implementation, flow control will be handled by the Kernel and the `ISKFunction` will be responsible for calling the delegate wrappers and adding data to the `SKEventArgs` that will be passed to the handlers. ```csharp class Kernel : IKernel { RunAsync() { var functionInvokingDelegateWrapper = new(this.FunctionInvoking); var functionInvokedDelegateWrapper = new(this.FunctionInvoked); var functionResult = await skFunction.InvokeAsync(context, functionInvokingDelegateWrapper, functionInvokingDelegateWrapper, functionInvokedDelegateWrapper); // Kernel will analyze the delegate results and make flow related decisions if (functionInvokingDelegateWrapper.EventArgs.CancelRequested ... ) { ... } if (functionInvokingDelegateWrapper.EventArgs.SkipRequested ... ) { ... } if (functionInvokedDelegateWrapper.EventArgs.Repeat ... ) { ... } } } class SemanticFunction : ISKFunction { InvokeAsync( SKContext context, FunctionInvokingDelegateWrapper functionInvokingDelegateWrapper, FunctionInvokedDelegateWrapper functionInvokedDelegateWrapper) { // The Semantic will have to call the delegate wrappers and share responsibility with the `Kernel`. if (functionInvokingDelegateWrapper.Handler is not null) { var renderedPrompt = await this.RenderPromptTemplateAsync(context); functionInvokingDelegateWrapper.EventArgs.RenderedPrompt = renderedPrompt; functionInvokingDelegateWrapper.Handler.Invoke(this, functionInvokingDelegateWrapper.EventArgs); if (functionInvokingDelegateWrapper.EventArgs?.CancelToken.IsCancellationRequested ?? false) { // Need to enforce an non processed result return new SKFunctionResult(context); //OR make InvokeAsync allow returning null FunctionResult? return null; } } } } // Wrapper for the EventHandler class FunctionDelegateWrapper where TEventArgs : SKEventArgs { FunctionInvokingDelegateWrapper(EventHandler eventHandler) {} // Set allows specialized eventargs to be set. public TEventArgs EventArgs { get; set; } public EventHandler Handler => _eventHandler; } ``` ### Pros and Cons Pros: - `ISKFunction` has less code/complexity to handle and expose data (Rendered Prompt) and state in the EventArgs. - `Kernel` is not aware of `SemanticFunction` implementation details or any other `ISKFunction` implementation - `Kernel` has less code/complexity - Could be extensible to show dedicated EventArgs per custom `ISKFunctions` implementation, including prompts for semantic functions Cons: - Unable to add new events if needed (ISKFunction interface change needed) - Functions need to implement behavior related to dependency (Kernel) events - Since Kernel needs to interact with the result of an event handler, a wrapper strategy is needed to access results by reference at the kernel level (control of flow) - Passing Kernel event handlers full responsibility downstream to the functions don't sound quite right (Single Responsibility) ### Option 4: Delegate to the ISKFunction how to handle events (SKContext Delegates approach) Add Kernel event handler delegate wrappers to `ISKFunction.InvokeAsync` interface. This approach shares the responsibility of handling the events between the `Kernel` and the `ISKFunction` implementation, flow control will be handled by the Kernel and the `ISKFunction` will be responsible for calling the delegate wrappers and adding data to the `SKEventArgs` that will be passed to the handlers. ```csharp class Kernel : IKernel { CreateNewContext() { var context = new SKContext(...); context.AddEventHandlers(this.FunctionInvoking, this.FunctionInvoked); return context; } RunAsync() { functionResult = await skFunction.InvokeAsync(context, ...); if (this.IsCancelRequested(functionResult.Context))) break; if (this.IsSkipRequested(functionResult.Context)) continue; if (this.IsRepeatRequested(...)) goto repeat; ... } } class SKContext { internal EventHandlerWrapper? FunctionInvokingHandler { get; private set; } internal EventHandlerWrapper? FunctionInvokedHandler { get; private set; } internal SKContext( ... ICollection? eventHandlerWrappers = null { ... this.InitializeEventWrappers(eventHandlerWrappers); } void InitializeEventWrappers(ICollection? eventHandlerWrappers) { if (eventHandlerWrappers is not null) { foreach (var handler in eventHandlerWrappers) { if (handler is EventHandlerWrapper invokingWrapper) { this.FunctionInvokingHandler = invokingWrapper; continue; } if (handler is EventHandlerWrapper invokedWrapper) { this.FunctionInvokedHandler = invokedWrapper; } } } } } class SemanticFunction : ISKFunction { InvokeAsync( SKContext context { string renderedPrompt = await this._promptTemplate.RenderAsync(context, cancellationToken).ConfigureAwait(false); this.CallFunctionInvoking(context, renderedPrompt); if (this.IsInvokingCancelOrSkipRequested(context, out var stopReason)) { return new StopFunctionResult(this.Name, this.PluginName, context, stopReason!.Value); } string completion = await GetCompletionsResultContentAsync(...); var result = new FunctionResult(this.Name, this.PluginName, context, completion); result.Metadata.Add(SemanticFunction.RenderedPromptMetadataKey, renderedPrompt); this.CallFunctionInvoked(result, context, renderedPrompt); if (this.IsInvokedCancelRequested(context, out stopReason)) { return new StopFunctionResult(this.Name, this.PluginName, context, result.Value, stopReason!.Value); } return result; } } ``` ### Pros and Cons Pros: - `ISKFunction` has less code/complexity to handle and expose data (Rendered Prompt) and state in the EventArgs. - `Kernel` is not aware of `SemanticFunction` implementation details or any other `ISKFunction` implementation - `Kernel` has less code/complexity - Could be extensible to show dedicated EventArgs per custom `ISKFunctions` implementation, including prompts for semantic functions - More extensible as `ISKFunction` interface doesn't need to change to add new events. - `SKContext` can be extended to add new events without introducing breaking changes. Cons: - Functions now need to implement logic to handle in-context events - Since Kernel needs to interact with the result of an event handler, a wrapper strategy is needed to access results by reference at the kernel level (control of flow) - Passing Kernel event handlers full responsibility downstream to the functions don't sound quite right (Single Responsibility) ## Decision outcome ### Option 4: Delegate to the ISKFunction how to handle events (SKContext Delegates approach) This allow the functions to implement some of the kernel logic but has the big benefit of not splitting logic in different methods for the same Execution Context. Biggest benefit: **`ISKFunction` has less code/complexity to handle and expose data and state in the EventArgs.** **`ISKFunction` interface doesn't need to change to add new events.** This implementation allows to get the renderedPrompt in the InvokeAsync without having to manage the context and the prompt in different methods. The above also applies for any other data that is available in the invocation and can be added as a new EventArgs property. ================================================ FILE: docs/decisions/0019-semantic-function-multiple-model-support.md ================================================ --- # These are optional elements.

By service id. - A Service id uniquely identifies a registered AI Service and is typically defined in the scope of an application. 1. By developer defined strategy. - A _developer defined strategy_ is a code first approach where a developer provides the logic. 1. By model id. - A model id uniquely identifies a Large Language Model. Multiple AI service providers can support the same LLM. 1. By arbitrary AI service attributes - E.g. an AI service can define a provider id which uniquely identifies an AI provider e.g. "Azure OpenAI", "OpenAI", "Hugging Face" **This ADR focuses on items 1 & 2 in the above list. To implement 3 & 4 we need to provide the ability to store `AIService` metadata.** ## Decision Outcome Support use cases 1 & 2 listed in this ADR and create separate ADR to add support for AI service metadata. ## Descriptions of the Use Cases **Note: All code is pseudo code and does not accurately reflect what the final implementations will look like.** ### Select Model Request Settings by Service Id _As a developer using the Semantic Kernel I can configure multiple request settings for a semantic function and associate each one with a service id so that the correct request settings are used when different services are used to execute my semantic function._ The semantic function template configuration allows multiple model request settings to be configured. In this case the developer configures different settings based on the service id that is used to execute the semantic function. In the example below the semantic function is executed with "AzureText" using `max_tokens=60` because "AzureText" is the first service id in the list of models configured for the prompt. ```csharp // Configure a Kernel with multiple LLM's IKernel kernel = new KernelBuilder() .WithLoggerFactory(ConsoleLogger.LoggerFactory) .WithAzureTextCompletionService(deploymentName: aoai.DeploymentName, endpoint: aoai.Endpoint, serviceId: "AzureText", apiKey: aoai.ApiKey) .WithAzureChatCompletionService(deploymentName: aoai.ChatDeploymentName, endpoint: aoai.Endpoint, serviceId: "AzureChat", apiKey: aoai.ApiKey) .WithOpenAITextCompletionService(modelId: oai.ModelId, serviceId: "OpenAIText", apiKey: oai.ApiKey, setAsDefault: true) .WithOpenAIChatCompletionService(modelId: oai.ChatModelId, serviceId: "OpenAIChat", apiKey: oai.ApiKey, setAsDefault: true) .Build(); // Configure semantic function with multiple LLM request settings var modelSettings = new List { new OpenAIRequestSettings() { ServiceId = "AzureText", MaxTokens = 60 }, new OpenAIRequestSettings() { ServiceId = "AzureChat", MaxTokens = 120 }, new OpenAIRequestSettings() { ServiceId = "OpenAIText", MaxTokens = 180 }, new OpenAIRequestSettings() { ServiceId = "OpenAIChat", MaxTokens = 240 } }; var prompt = "Hello AI, what can you do for me?"; var promptTemplateConfig = new PromptTemplateConfig() { ModelSettings = modelSettings }; var func = kernel.CreateSemanticFunction(prompt, config: promptTemplateConfig, "HelloAI"); // Semantic function is executed with AzureText using max_tokens=60 result = await kernel.RunAsync(func); ``` This works by using the `IAIServiceSelector` interface as the strategy for selecting the AI service and request settings to user when invoking a semantic function. The interface is defined as follows: ```csharp public interface IAIServiceSelector { (T?, AIRequestSettings?) SelectAIService( string renderedPrompt, IAIServiceProvider serviceProvider, IReadOnlyList? modelSettings) where T : IAIService; } ``` A default `OrderedIAIServiceSelector` implementation is provided which selects the AI service based on the order of the model request settings defined for the semantic function. - The implementation checks if a service exists which the corresponding service id and if it does it and the associated model request settings will be used. - In no model request settings are defined then the default text completion service is used. - A default set of request settings can be specified by leaving the service id undefined or empty, the first such default will be used. - If no default if specified and none of the specified services are available the operation will fail. ### Select AI Service and Model Request Settings By Developer Defined Strategy _As a developer using the Semantic Kernel I can provide an implementation which selects the AI service and request settings used to execute my function so that I can dynamically control which AI service and settings are used to execute my semantic function._ In this case the developer configures different settings based on the service id and provides an AI Service Selector which determines which AI Service will be used when the semantic function is executed. In the example below the semantic function is executed with whatever AI Service and AI Request Settings `MyAIServiceSelector` returns e.g. it will be possible to create an AI Service Selector that computes the token count of the rendered prompt and uses that to determine which service to use. ```csharp // Configure a Kernel with multiple LLM's IKernel kernel = new KernelBuilder() .WithLoggerFactory(ConsoleLogger.LoggerFactory) .WithAzureTextCompletionService(deploymentName: aoai.DeploymentName, endpoint: aoai.Endpoint, serviceId: "AzureText", apiKey: aoai.ApiKey) .WithAzureChatCompletionService(deploymentName: aoai.ChatDeploymentName, endpoint: aoai.Endpoint, serviceId: "AzureChat", apiKey: aoai.ApiKey) .WithOpenAITextCompletionService(modelId: oai.ModelId, serviceId: "OpenAIText", apiKey: oai.ApiKey, setAsDefault: true) .WithOpenAIChatCompletionService(modelId: oai.ChatModelId, serviceId: "OpenAIChat", apiKey: oai.ApiKey, setAsDefault: true) .WithAIServiceSelector(new MyAIServiceSelector()) .Build(); // Configure semantic function with multiple LLM request settings var modelSettings = new List { new OpenAIRequestSettings() { ServiceId = "AzureText", MaxTokens = 60 }, new OpenAIRequestSettings() { ServiceId = "AzureChat", MaxTokens = 120 }, new OpenAIRequestSettings() { ServiceId = "OpenAIText", MaxTokens = 180 }, new OpenAIRequestSettings() { ServiceId = "OpenAIChat", MaxTokens = 240 } }; var prompt = "Hello AI, what can you do for me?"; var promptTemplateConfig = new PromptTemplateConfig() { ModelSettings = modelSettings }; var func = kernel.CreateSemanticFunction(prompt, config: promptTemplateConfig, "HelloAI"); // Semantic function is executed with AI Service and AI request Settings dynamically determined result = await kernel.RunAsync(func, funcVariables); ``` ## More Information ### Select AI Service by Service Id The following use case is supported. Developers can create a `Kernel`` instance with multiple named AI services. When invoking a semantic function the service id (and optionally request settings to be used) can be specified. The named AI service will be used to execute the prompt. ```csharp var aoai = TestConfiguration.AzureOpenAI; var oai = TestConfiguration.OpenAI; // Configure a Kernel with multiple LLM's IKernel kernel = Kernel.Builder .WithLoggerFactory(ConsoleLogger.LoggerFactory) .WithAzureTextCompletionService(deploymentName: aoai.DeploymentName, endpoint: aoai.Endpoint, serviceId: "AzureText", apiKey: aoai.ApiKey) .WithAzureChatCompletionService(deploymentName: aoai.ChatDeploymentName, endpoint: aoai.Endpoint, serviceId: "AzureChat", apiKey: aoai.ApiKey) .WithOpenAITextCompletionService(modelId: oai.ModelId, serviceId: "OpenAIText", apiKey: oai.ApiKey) .WithOpenAIChatCompletionService(modelId: oai.ChatModelId, serviceId: "OpenAIChat", apiKey: oai.ApiKey) .Build(); // Invoke the semantic function and service and request settings to use result = await kernel.InvokeSemanticFunctionAsync(prompt, requestSettings: new OpenAIRequestSettings() { ServiceId = "AzureText", MaxTokens = 60 }); result = await kernel.InvokeSemanticFunctionAsync(prompt, requestSettings: new OpenAIRequestSettings() { ServiceId = "AzureChat", MaxTokens = 120 }); result = await kernel.InvokeSemanticFunctionAsync(prompt, requestSettings: new OpenAIRequestSettings() { ServiceId = "OpenAIText", MaxTokens = 180 }); result = await kernel.InvokeSemanticFunctionAsync(prompt, requestSettings: new OpenAIRequestSettings() { ServiceId = "OpenAIChat", MaxTokens = 240 }); ``` ================================================ FILE: docs/decisions/0020-prompt-syntax-mapping-to-completion-service-model.md ================================================ --- # These are optional elements.

With the addition of new chat completion prompt and potentially other prompt types, such as image, on the horizon, we need a way to map completion-specific prompt syntax to the corresponding completion service data model. For example, [the chat completion syntax](https://github.com/microsoft/semantic-kernel/blob/main/docs/decisions/0014-chat-completion-roles-in-prompt.md) in chat completion prompts: ```xml You are a creative assistant helping individuals and businesses with their innovative projects. I want to brainstorm the idea of {{$input}} ``` should be mapped to an instance of the [ChatHistory](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/src/SemanticKernel.Abstractions/AI/ChatCompletion/ChatHistory.cs) class with two chat messages: ```csharp var messages = new ChatHistory(); messages.Add(new ChatMessage(new AuthorRole("system"), "You are a creative assistant helping individuals and businesses with their innovative projects.")); messages.Add(new ChatMessage(new AuthorRole("user"), "I want to brainstorm the idea of {{$input}}")); ``` This ADR outlines potential options for the location of the prompt syntax mapping functionality. ## Considered Options **1. Completion connector classes.** This option proposes to have the completion connector classes responsible for the `prompt syntax -> completion service data model` mapping. The decision regarding whether this mapping functionality will be implemented in the connector classes themselves or delegated to mapper classes should be made during the implementation phase and is out of the scope of this ADR. Pros: - The `SemanticFunction` won't need to change to support the mapping of a new prompt syntax when new completion type connectors (audio, video, etc.) are added. - Prompts can be run by - Kernel.RunAsync - Completion connectors Cons: - Every new completion connector, whether of an existing type or a new type, will have to implement the mapping functionality **2. The SemanticFunction class.** This option proposes that the `SemanticFunction` class be responsible for the mapping. Similar to the previous option, the exact location of this functionality (whether in the `SemanticFunction` class or in the mapper classes) should be decided during the implementation phase. Pros: - New connectors of a new type or existing ones don't have to implement the mapping functionality Cons: - The `SemanticFunction` class has to be changed every time a new completion type needs to be supported by SK - Prompts can be run by Kernel.RunAsync method only. ## Decision Outcome It was agreed to go with the option 1 - `1. Completion connector classes` since it a more flexible solution and allows adding new connectors without modifying the `SemanticFunction` class. ================================================ FILE: docs/decisions/0021-aiservice-metadata.md ================================================ --- # These are optional elements. Feel free to remove any of them. status: {proposed} date: {2023-11-10} deciders: SergeyMenshykh, markwallace, rbarreto, dmytrostruk consulted: informed: --- # Add AI Service Metadata ## Context and Problem Statement Developers need to be able to know more information about the `IAIService` that will be used to execute a semantic function or a plan. Some examples of why they need this information: 1. As an SK developer I want to write a `IAIServiceSelector` which allows me to select the OpenAI service to used based on the configured model id so that I can select the optimum (could eb cheapest) model to use based on the prompt I am executing. 2. As an SK developer I want to write a pre-invocation hook which will compute the token size of a prompt before the prompt is sent to the LLM, so that I can determine the optimum `IAIService` to use. The library I am using to compute the token size of the prompt requires the model id. Current implementation of `IAIService` is empty. ```csharp public interface IAIService { } ``` We can retrieve `IAIService` instances using `T IKernel.GetService(string? name = null) where T : IAIService;` i.e., by service type and name (aka service id). The concrete instance of an `IAIService` can have different attributes depending on the service provider e.g. Azure OpenAI has a deployment name and OpenAI services have a model id. Consider the following code snippet: ```csharp IKernel kernel = new KernelBuilder() .WithLoggerFactory(ConsoleLogger.LoggerFactory) .WithAzureChatCompletionService( deploymentName: chatDeploymentName, endpoint: endpoint, serviceId: "AzureOpenAIChat", apiKey: apiKey) .WithOpenAIChatCompletionService( modelId: openAIModelId, serviceId: "OpenAIChat", apiKey: openAIApiKey) .Build(); var service = kernel.GetService("OpenAIChat"); ``` For Azure OpenAI we create the service with a deployment name. This is an arbitrary name specified by the person who deployed the AI model e.g. it could be `eastus-gpt-4` or `foo-bar`. For OpenAI we create the service with a model id. This must match one of the deployed OpenAI models. From the perspective of a prompt creator using OpenAI, they will typically tune their prompts based on the model. So when the prompt is executed we need to be able to retrieve the service using the model id. As shown in the code snippet above the `IKernel` only supports retrieving an `IAService` instance by id. Additionally the `IChatCompletion` is a generic interface so it doesn't contain any properties which provide information about a specific connector instance. ## Decision Drivers * We need a mechanism to store generic metadata for an `IAIService` instance. * It will be the responsibility of the concrete `IAIService` instance to store the metadata that is relevant e.g., model id for OpenAI and HuggingFace AI services. * We need to be able to iterate over the available `IAIService` instances. ## Considered Options * Option #1 * Extend `IAIService` to include the following properties: * `string? ModelId { get; }` which returns the model id. It will be the responsibility of each `IAIService` implementation to populate this with the appropriate value. * `IReadOnlyDictionary Attributes { get; }` which returns the attributes as a readonly dictionary. It will be the responsibility of each `IAIService` implementation to populate this with the appropriate metadata. * Extend `INamedServiceProvider` to include this method `ICollection GetServices() where T : TService;` * Extend `OpenAIKernelBuilderExtensions` so that `WithAzureXXX` methods will include a `modelId` property if a specific model can be targeted. * Option #2 * Extend `IAIService` to include the following method: * `T? GetAttributes() where T : AIServiceAttributes;` which returns an instance of `AIServiceAttributes`. It will be the responsibility of each `IAIService` implementation to define it's own service attributes class and populate this with the appropriate values. * Extend `INamedServiceProvider` to include this method `ICollection GetServices() where T : TService;` * Extend `OpenAIKernelBuilderExtensions` so that `WithAzureXXX` methods will include a `modelId` property if a specific model can be targeted. * Option #3 * Option #2 * Extend `IAIService` to include the following properties: * `public IReadOnlyDictionary Attributes => this.InternalAttributes;` which returns a read only dictionary. It will be the responsibility of each `IAIService` implementation to define it's own service attributes class and populate this with the appropriate values. * `ModelId` * `Endpoint` * `ApiVersion` * Extend `INamedServiceProvider` to include this method `ICollection GetServices() where T : TService;` * Extend `OpenAIKernelBuilderExtensions` so that `WithAzureXXX` methods will include a `modelId` property if a specific model can be targeted. These options would be used as follows: As an SK developer I want to write a custom `IAIServiceSelector` which will select an AI service based on the model id because I want to restrict which LLM is used. In the sample below the service selector implementation looks for the first service that is a GPT3 model. ### Option 1 ``` csharp public class Gpt3xAIServiceSelector : IAIServiceSelector { public (T?, AIRequestSettings?) SelectAIService(string renderedPrompt, IAIServiceProvider serviceProvider, IReadOnlyList? modelSettings) where T : IAIService { var services = serviceProvider.GetServices(); foreach (var service in services) { if (!string.IsNullOrEmpty(service.ModelId) && service.ModelId.StartsWith("gpt-3", StringComparison.OrdinalIgnoreCase)) { Console.WriteLine($"Selected model: {service.ModelId}"); return (service, new OpenAIRequestSettings()); } } throw new SKException("Unable to find AI service for GPT 3.x."); } } ``` ## Option 2 ``` csharp public class Gpt3xAIServiceSelector : IAIServiceSelector { public (T?, AIRequestSettings?) SelectAIService(string renderedPrompt, IAIServiceProvider serviceProvider, IReadOnlyList? modelSettings) where T : IAIService { var services = serviceProvider.GetServices(); foreach (var service in services) { var serviceModelId = service.GetAttributes()?.ModelId; if (!string.IsNullOrEmpty(serviceModelId) && serviceModelId.StartsWith("gpt-3", StringComparison.OrdinalIgnoreCase)) { Console.WriteLine($"Selected model: {serviceModelId}"); return (service, new OpenAIRequestSettings()); } } throw new SKException("Unable to find AI service for GPT 3.x."); } } ``` ## Option 3 ```csharp public (T?, AIRequestSettings?) SelectAIService(string renderedPrompt, IAIServiceProvider serviceProvider, IReadOnlyList? modelSettings) where T : IAIService { var services = serviceProvider.GetServices(); foreach (var service in services) { var serviceModelId = service.GetModelId(); var serviceOrganization = service.GetAttribute(OpenAIServiceAttributes.OrganizationKey); var serviceDeploymentName = service.GetAttribute(AzureOpenAIServiceAttributes.DeploymentNameKey); if (!string.IsNullOrEmpty(serviceModelId) && serviceModelId.StartsWith("gpt-3", StringComparison.OrdinalIgnoreCase)) { Console.WriteLine($"Selected model: {serviceModelId}"); return (service, new OpenAIRequestSettings()); } } throw new SKException("Unable to find AI service for GPT 3.x."); } ``` ## Decision Outcome Chosen option: Option 1, because it's a simple implementation and allows easy iteration over all possible attributes. ================================================ FILE: docs/decisions/0021-json-serializable-custom-types.md ================================================ --- status: proposed contact: dehoward date: 2023-11-06 deciders: alliscode, markwallace-microsoft consulted: informed: --- # JSON Serializable Custom Types ## Context and Problem Statement This ADR aims to simplify the usage of custom types by allowing developers to use any type that can be serialized using `System.Text.Json`. Standardizing on a JSON-serializable type is necessary to allow functions to be described using a JSON Schema within a planner's function manual. Using a JSON Schema to describe a function's input and output types will allow the planner to validate that the function is being used correctly. Today, use of custom types within Semantic Kernel requires developers to implement a custom `TypeConverter` to convert to/from the string representation of the type. This is demonstrated in [Functions/MethodFunctions_Advanced] as seen below: ```csharp [TypeConverter(typeof(MyCustomTypeConverter))] private sealed class MyCustomType { public int Number { get; set; } public string? Text { get; set; } } private sealed class MyCustomTypeConverter : TypeConverter { public override bool CanConvertFrom(ITypeDescriptorContext? context, Type sourceType) => true; public override object? ConvertFrom(ITypeDescriptorContext? context, CultureInfo? culture, object value) { return JsonSerializer.Deserialize((string)value); } public override object? ConvertTo(ITypeDescriptorContext? context, CultureInfo? culture, object? value, Type destinationType) { return JsonSerializer.Serialize(value); } } ``` The above approach will now only be needed when a custom type cannot be serialized using `System.Text.Json`. ## Considered Options **1. Fallback to serialization using `System.Text.Json` if a `TypeConverter` is not available for the given type** - Primitive types will be handled using their native `TypeConverter`s - We preserve the use of the native `TypeConverter` for primitive types to prevent any lossy conversions. - Complex types will be handled by their registered `TypeConverter`, if provided. - If no `TypeConverter` is registered for a complex type, our own `JsonSerializationTypeConverter` will be used to attempt JSON serialization/deserialization using `System.Text.Json`. - A detailed error message will be thrown if the type cannot be serialized/deserialized. This will change the `GetTypeConverter()` method in `NativeFunction.cs` to look like the following, where before `null` was returned if no `TypeConverter` was found for the type: ```csharp private static TypeConverter GetTypeConverter(Type targetType) { if (targetType == typeof(byte)) { return new ByteConverter(); } if (targetType == typeof(sbyte)) { return new SByteConverter(); } if (targetType == typeof(bool)) { return new BooleanConverter(); } if (targetType == typeof(ushort)) { return new UInt16Converter(); } if (targetType == typeof(short)) { return new Int16Converter(); } if (targetType == typeof(char)) { return new CharConverter(); } if (targetType == typeof(uint)) { return new UInt32Converter(); } if (targetType == typeof(int)) { return new Int32Converter(); } if (targetType == typeof(ulong)) { return new UInt64Converter(); } if (targetType == typeof(long)) { return new Int64Converter(); } if (targetType == typeof(float)) { return new SingleConverter(); } if (targetType == typeof(double)) { return new DoubleConverter(); } if (targetType == typeof(decimal)) { return new DecimalConverter(); } if (targetType == typeof(TimeSpan)) { return new TimeSpanConverter(); } if (targetType == typeof(DateTime)) { return new DateTimeConverter(); } if (targetType == typeof(DateTimeOffset)) { return new DateTimeOffsetConverter(); } if (targetType == typeof(Uri)) { return new UriTypeConverter(); } if (targetType == typeof(Guid)) { return new GuidConverter(); } if (targetType.GetCustomAttribute() is TypeConverterAttribute tca && Type.GetType(tca.ConverterTypeName, throwOnError: false) is Type converterType && Activator.CreateInstance(converterType) is TypeConverter converter) { return converter; } // now returns a JSON-serializing TypeConverter by default, instead of returning null return new JsonSerializationTypeConverter(); } private sealed class JsonSerializationTypeConverter : TypeConverter { public override bool CanConvertFrom(ITypeDescriptorContext? context, Type sourceType) => true; public override object? ConvertFrom(ITypeDescriptorContext? context, CultureInfo? culture, object value) { return JsonSerializer.Deserialize((string)value); } public override object? ConvertTo(ITypeDescriptorContext? context, CultureInfo? culture, object? value, Type destinationType) { return JsonSerializer.Serialize(value); } } ``` _When is serialization/deserialization required?_ Required - **Native to Semantic:** Passing variables from Native to Semantic **will** require serialization of the output of the Native Function from complex type to string so that it can be passed to the LLM. - **Semantic to Native:** Passing variables from Semantic to Native **will** require de-serialization of the output of the Semantic Function between string to the complex type format that the Native Function is expecting. Not required - **Native to Native:** Passing variables from Native to Native **will not** require any serialization or deserialization as the complex type can be passed as-is. - **Semantic to Semantic:** Passing variables from Semantic to Semantic **will not** require any serialization or deserialization as the the complex type will be passed around using its string representation. **2. Only use native serialization methods** This option was originally considered, which would have effectively removed the use of the `TypeConverter`s in favor of a simple `JsonConverter`, but it was pointed out that this may result in lossy conversion between primitive types. For example, when converting from a `float` to an `int`, the primitive may be truncated in a way by the native serialization methods that does not provide an accurate result. ## Decision Outcome ================================================ FILE: docs/decisions/0022-skfunction.md ================================================ --- # These are optional elements.

Handlebars provides a simple and expressive syntax for creating dynamic templates with logic and data. However, Handlebars does not have built-in support for some features and scenarios that are relevant for our use cases, such as: - Marking a block of text as a message with a role for chat completion connectors. - Invoking functions from the kernel and passing parameters to them. - Setting and getting variables in the template context. - Performing common operations such as concatenation, arithmetic, comparison, and JSON serialization. - Supporting different output types and formats for the rendered template. Therefore, we need to extend Handlebars with custom helpers that can address these gaps and provide a consistent and convenient way for prompt and planner engineers to write templates. First, we will do this by **_baking in a defined set of custom system helpers_** for common operations and utilities that are not provided any the built-in Handlebars helpers, which: - Allows us full control over what functionality can be executed by the Handlebars template factory. - Enhances the functionality and usability of the template factory, by providing helpers for common operations and utilities that are not provided by any built-in Handlebars helpers but are commonly hallucinated by the model. - Improves the expressiveness and readability of the rendered template, as the helpers can be used to perform simple or complex logic or transformations on the template data / arguments. - Provides flexibility and convenience for the users, as they can: - Choose the syntax, and - Extend, add, or omit certain helpers to best suits their needs and preferences. - Allows for customization of specific operations or utilities that may have different behavior or requirements, such as handling output types, formats, or errors. These helpers would handle the evaluation of the arguments, the execution of the operation or utility, and the writing of the result to the template. Examples of such operations are `{{concat string1 string2 ...}}`, `{{equal value1 value2}}`, `{{json object}}`, `{{set name=value}}`, `{{get name}}`, `{{or condition1 condition2}}`, etc. Secondly, we have to **_expose the functions that are registered in the Kernel as helpers_** to the Handlebars template factory. Options for this are detailed below. ## Decision Drivers - We want to leverage the existing Handlebars helpers, syntax, and mechanisms for loading helpers as much as possible, without introducing unnecessary complexity or inconsistency. - We want to provide helpers that are useful and intuitive for prompt and SK engineers. - We want to ensure that the helpers are well-documented, tested, and maintained, and that they do not conflict with each other or with the built-in Handlebars helpers. - We want to support different output types and formats for the rendered template, such as text, JSON, or complex objects, and allow the template to specify the desired output type. ## Considered Options We considered the following options for extending Handlebars with kernel functions as custom helpers: **1. Use a single helper for invoking functions from the kernel.** This option would use a generic helper, such as `{{invoke pluginName-functionName param1=value1 param2=value2 ...}}`, to call any function from the kernel and pass parameters to it. The helper would handle the execution of the function, the conversion of the parameters and the result, and the writing of the result to the template. **2. Use a separate helper for each function from the kernel.** This option would register a new helper for each function, such as `{{pluginName-functionName param1=value1 param2=value2 ...}}`, to handle the execution of the function, the conversion of the parameters and the result, and the writing of the result to the template. ## Pros and Cons ### 1. Use a single generic helper for invoking functions from the kernel Pros: - Simplifies the registration and maintenance of the helper, as only one helper, `invoke`, needs to be defined and updated. - Provides a consistent and uniform syntax for calling any function from the kernel, regardless of the plugin or function name, parameter details, or the result. - Allows for customization and special logic of kernel functions, such as handling output types, execution restrictions, or errors. - Allows the use of positional or named arguments, as well as hash arguments, for passing parameters to the function. Cons: - Reduces the expressiveness and readability of the template, as the function name and parameters are wrapped in a generic helper invocation. - Adds additional syntax for the model to learn and keep track of, potentially leading to more errors during render. ### 2. Use a generic helper for _each_ function from the kernel Pros: - Has all the benefits of option 1, but largely improves the expressiveness and readability of the template, as the function name and parameters are directly written in the template. - Maintains ease of maintenance for handling each function, as each helper will follow the same templated logic for registration and execution. Cons: - May cause conflicts or confusion with the built-in Handlebars helpers or the kernel variables, if the function name or the parameter name matches them. ## Decision Outcome We decided to go with option 2: providing special helpers to invoke any function in the kernel. These helpers will follow the same logic and syntax for each registered function. We believe that this approach, alongside the custom system helpers that will enable special utility logic or behavior, provides the best balance between simplicity, expressiveness, flexibility, and functionality for the Handlebars template factory and our users. With this approach, - We will allow customers to use any of the built-in [Handlebars.Net helpers](https://github.com/Handlebars-Net/Handlebars.Net.Helpers). - We will provide utility helpers, which are registered by default. - We will provide prompt helpers (e.g. chat message), which are registered by default. - We will register all plugin functions registered on the `Kernel`. - We will allow customers to control which plugins are registered as helpers and the syntax of helpers' signatures. - By default, we will honor all options defined in [HandlebarsHelperOptions](https://github.com/Handlebars-Net/Handlebars.Net.Helpers/blob/8f7c9c082e18845f6a620bbe34bf4607dcba405b/src/Handlebars.Net.Helpers/Options/HandlebarsHelpersOptions.cs#L12). - Additionally, we will extend this configuration to include a `RegisterCustomHelpersCallback` option that users can set to register custom helpers. - We will allow Kernel function arguments to be easily accessed, i.e., function variables and execution settings, via a `KernelArguments` object. - We will allow customers to control when plugin functions are registered as helpers. - By default, this is done when template is rendered. - Optionally, this can be done when the Handlebars template factory is constructed by passing in a Plugin collection. - If conflicts arise between built-in helpers, variables, or kernel objects: - We will throw an error clearly explaining what the issue is, as well as - Allow customers to provide their own implementations and overrides, including an option to not register default helpers. This can be done by setting `Options.Categories` to an empty array `[]`. We also decided to follow some guidelines and best practices for designing and implementing the helpers, such as: - Documenting the purpose, syntax, parameters, and behavior of each helper, and providing examples and tests for them. - Naming the helpers in a clear and consistent way, and avoiding conflicts or confusion with the built-in Handlebars helpers or the kernel functions or variables. - Using standalone function names for custom system helpers (i.e., json, set) - Using the delimiter "`-`" for helpers registered to handle the kernel functions, to distinguish them from each other and from our system or built-in Handlebars helpers. - Supporting both positional and hash arguments, for passing parameters to the helpers, and validating the arguments for the required type and count. - Handling the output types, formats, and errors of the helpers, including complex types or JSON schemas. - Implementing the helpers in a performant and secure way, and avoiding any side effects or unwanted modifications to the template context or data. Effectively, there will be four buckets of helpers enabled in the Handlebars Template Engine: 1. Default helpers from the Handlebars library, including: - [Built-in helpers](https://handlebarsjs.com/guide/builtin-helpers.html) that enable loops and conditions (#if, #each, #with, #unless) - [Handlebars.Net.Helpers](https://github.com/Handlebars-Net/Handlebars.Net.Helpers/wiki) 2. Functions in the kernel 3. Helpers helpful to prompt engineers (i.e., message, or) 4. Utility helpers that can be used to perform simple logic or transformations on the template data or arguments (i.e., set, get, json, concat, equals, range, array) ### Pseudocode for the Handlebars Prompt Template Engine A prototype implementation of a Handlebars prompt template factory with built-in helpers could look something like this: ```csharp /// Options for Handlebars helpers (built-in and custom). public sealed class HandlebarsPromptTemplateOptions : HandlebarsHelpersOptions { // Categories tracking built-in system helpers public enum KernelHelperCategories { Prompt, Plugin, Context, String, ... } /// Default character to use for delimiting plugin name and function name in a Handlebars template. public string DefaultNameDelimiter { get; set; } = "-"; /// Delegate for registering custom helpers. public delegate void RegisterCustomHelpersCallback(IHandlebars handlebarsInstance, KernelArguments executionContext); /// Callback for registering custom helpers. public RegisterCustomHelpersCallback? RegisterCustomHelpers { get; set; } = null; // Pseudocode, some combination of both KernelHelperCategories and the default HandlebarsHelpersOptions.Categories. public List AllCategories = KernelHelperCategories.AddRange(Categories); } ``` ```csharp // Handlebars Prompt Template internal class HandlebarsPromptTemplate : IPromptTemplate { public async Task RenderAsync(Kernel kernel, KernelArguments arguments, CancellationToken cancellationToken = default) { arguments ??= new(); var handlebarsInstance = HandlebarsDotNet.Handlebars.Create(); // Add helpers for kernel functions KernelFunctionHelpers.Register(handlebarsInstance, kernel, arguments, this._options.PrefixSeparator, cancellationToken); // Add built-in system helpers KernelSystemHelpers.Register(handlebarsInstance, arguments, this._options); // Register any custom helpers if (this._options.RegisterCustomHelpers is not null) { this._options.RegisterCustomHelpers(handlebarsInstance, arguments); } ... return await Task.FromResult(prompt).ConfigureAwait(true); } } ``` ```csharp /// Extension class to register Kernel functions as helpers. public static class KernelFunctionHelpers { public static void Register( IHandlebars handlebarsInstance, Kernel kernel, KernelArguments executionContext, string nameDelimiter, CancellationToken cancellationToken = default) { kernel.Plugins.GetFunctionsMetadata().ToList() .ForEach(function => RegisterFunctionAsHelper(kernel, executionContext, handlebarsInstance, function, nameDelimiter, cancellationToken) ); } private static void RegisterFunctionAsHelper( Kernel kernel, KernelArguments executionContext, IHandlebars handlebarsInstance, KernelFunctionMetadata functionMetadata, string nameDelimiter, CancellationToken cancellationToken = default) { // Register helper for each function handlebarsInstance.RegisterHelper(fullyResolvedFunctionName, (in HelperOptions options, in Context context, in Arguments handlebarsArguments) => { // Get parameters from template arguments; check for required parameters + type match // If HashParameterDictionary ProcessHashArguments(functionMetadata, executionContext, handlebarsArguments[0] as IDictionary, nameDelimiter); // Else ProcessPositionalArguments(functionMetadata, executionContext, handlebarsArguments); KernelFunction function = kernel.Plugins.GetFunction(functionMetadata.PluginName, functionMetadata.Name); InvokeSKFunction(kernel, function, GetKernelArguments(executionContext), cancellationToken); }); } ... } ``` ```csharp /// Extension class to register additional helpers as Kernel System helpers. public static class KernelSystemHelpers { public static void Register(IHandlebars handlebarsInstance, KernelArguments arguments, HandlebarsPromptTemplateOptions options) { RegisterHandlebarsDotNetHelpers(handlebarsInstance, options); RegisterSystemHelpers(handlebarsInstance, arguments, options); } // Registering all helpers provided by https://github.com/Handlebars-Net/Handlebars.Net.Helpers. private static void RegisterHandlebarsDotNetHelpers(IHandlebars handlebarsInstance, HandlebarsPromptTemplateOptions helperOptions) { HandlebarsHelpers.Register(handlebarsInstance, optionsCallback: options => { ...helperOptions }); } // Registering all helpers built by the SK team to support the kernel. private static void RegisterSystemHelpers( IHandlebars handlebarsInstance, KernelArguments arguments, HandlebarsPromptTemplateOptions helperOptions) { // Where each built-in helper will have its own defined class, following the same pattern that is used by Handlebars.Net.Helpers. // https://github.com/Handlebars-Net/Handlebars.Net.Helpers if (helperOptions.AllCategories contains helperCategory) ... KernelPromptHelpers.Register(handlebarsContext); KernelPluginHelpers.Register(handlebarsContext); KernelStringHelpers..Register(handlebarsContext); ... } } ``` **Note: This is just a prototype implementation for illustration purposes only.** Handlebars supports different object types as variables on render. This opens up the option to use objects outright rather than just strings in semantic functions, i.e., loop over arrays or access properties of complex objects, without serializing or deserializing objects before invocation. ================================================ FILE: docs/decisions/0023-kernel-streaming.md ================================================ --- # These are optional elements. Feel free to remove any of them. status: proposed date: 2023-11-13 deciders: rogerbarreto,markwallace-microsoft,SergeyMenshykh,dmytrostruk consulted: informed: --- # Streaming Capability for Kernel and Functions usage - Phase 1 ## Context and Problem Statement It is quite common in co-pilot implementations to have a streamlined output of messages from the LLM (large language models)M and currently that is not possible while using ISKFunctions.InvokeAsync or Kernel.RunAsync methods, which enforces users to work around the Kernel and Functions to use `ITextCompletion` and `IChatCompletion` services directly as the only interfaces that currently support streaming. Currently streaming is a capability that not all providers do support and this as part of our design we try to ensure the services will have the proper abstractions to support streaming not only of text but be open to other types of data like images, audio, video, etc. Needs to be clear for the sk developer when he is attempting to get streaming data. ## Decision Drivers 1. The sk developer should be able to get streaming data from the Kernel and Functions using Kernel.RunAsync or ISKFunctions.InvokeAsync methods 2. The sk developer should be able to get the data in a generic way, so the Kernel and Functions can be able to stream data of any type, not limited to text. 3. The sk developer when using streaming from a model that does not support streaming should still be able to use it with only one streaming update representing the whole data. ## Out of Scope - Streaming with plans will not be supported in this phase. Attempting to do so will throw an exception. - Kernel streaming will not support multiple functions (pipeline). - Input streaming will not be supported in this phase. - Post Hook Skipping, Repeat and Cancelling of streaming functions are not supported. ## Considered Options ### Option 1 - Dedicated Streaming Interfaces Using dedicated streaming interfaces that allow the sk developer to get the streaming data in a generic way, including string, byte array directly from the connector as well as allowing the Kernel and Functions implementations to be able to stream data of any type, not limited to text. This approach also exposes dedicated interfaces in the kernel and functions to use streaming making it clear to the sk developer what is the type of data being returned in IAsyncEnumerable format. `ITextCompletion` and `IChatCompletion` will have new APIs to get `byte[]` and `string` streaming data directly as well as the specialized `StreamingContent` return. The sk developer will be able to specify a generic type to the `Kernel.RunStreamingAsync()` and `ISKFunction.InvokeStreamingAsync` to get the streaming data. If the type is not specified, the Kernel and Functions will return the data as StreamingContent. If the type is not specified or if the string representation cannot be cast, an exception will be thrown. If the type specified is `StreamingContent` or another any type supported by the connector no error will be thrown. ## User Experience Goal ```csharp //(providing the type at as generic parameter) // Getting a Raw Streaming data from Kernel await foreach(string update in kernel.RunStreamingAsync(function, variables)) // Getting a String as Streaming data from Kernel await foreach(string update in kernel.RunStreamingAsync(function, variables)) // Getting a StreamingContent as Streaming data from Kernel await foreach(StreamingContent update in kernel.RunStreamingAsync(variables, function)) // OR await foreach(StreamingContent update in kernel.RunStreamingAsync(function, variables)) // defaults to Generic above) { Console.WriteLine(update); } ``` Abstraction class for any stream content, connectors will be responsible to provide the specialized type of `StreamingContent` which will contain the data as well as any metadata related to the streaming result. ```csharp public abstract class StreamingContent { public abstract int ChoiceIndex { get; } /// Returns a string representation of the chunk content public abstract override string ToString(); /// Abstract byte[] representation of the chunk content in a way it could be composed/appended with previous chunk contents. /// Depending on the nature of the underlying type, this method may be more efficient than . public abstract byte[] ToByteArray(); /// Internal chunk content object reference. (Breaking glass). /// Each connector will have its own internal object representing the content chunk content. /// The usage of this property is considered "unsafe". Use it only if strictly necessary. public object? InnerContent { get; } /// The metadata associated with the content. public Dictionary? Metadata { get; set; } /// The current context associated the function call. internal SKContext? Context { get; set; } /// Inner content object reference protected StreamingContent(object? innerContent) { this.InnerContent = innerContent; } } ``` Specialization example of a StreamingChatContent ```csharp // public class StreamingChatContent : StreamingContent { public override int ChoiceIndex { get; } public FunctionCall? FunctionCall { get; } public string? Content { get; } public AuthorRole? Role { get; } public string? Name { get; } public StreamingChatContent(AzureOpenAIChatMessage chatMessage, int resultIndex) : base(chatMessage) { this.ChoiceIndex = resultIndex; this.FunctionCall = chatMessage.InnerChatMessage?.FunctionCall; this.Content = chatMessage.Content; this.Role = new AuthorRole(chatMessage.Role.ToString()); this.Name = chatMessage.InnerChatMessage?.Name; } public override byte[] ToByteArray() => Encoding.UTF8.GetBytes(this.ToString()); public override string ToString() => this.Content ?? string.Empty; } ``` `IChatCompletion` and `ITextCompletion` interfaces will have new APIs to get a generic streaming content data. ```csharp interface ITextCompletion + IChatCompletion { IAsyncEnumerable GetStreamingContentAsync(...); // Throw exception if T is not supported } interface IKernel { // Get streaming function content of T IAsyncEnumerable RunStreamingAsync(ContextVariables variables, ISKFunction function); } interface ISKFunction { // Get streaming function content of T IAsyncEnumerable InvokeStreamingAsync(SKContext context); } ``` ## Prompt/Semantic Functions Behavior When Prompt Functions are invoked using the Streaming API, they will attempt to use the Connectors streaming implementation. The connector will be responsible to provide the specialized type of `StreamingContent` and even if the underlying backend API don't support streaming the output will be one streamingcontent with the whole data. ## Method/Native Functions Behavior Method Functions will support `StreamingContent` automatically with as a `StreamingMethodContent` wrapping the object returned in the iterator. ```csharp public sealed class StreamingMethodContent : StreamingContent { public override int ChoiceIndex => 0; /// Method object value that represents the content chunk public object Value { get; } /// Default implementation public override byte[] ToByteArray() { if (this.Value is byte[]) { // If the method value is byte[] we return it directly return (byte[])this.Value; } // By default if a native value is not byte[] we output the UTF8 string representation of the value return Encoding.UTF8.GetBytes(this.Value?.ToString()); } /// public override string ToString() { return this.Value.ToString(); } /// /// Initializes a new instance of the class. /// /// Underlying object that represents the chunk public StreamingMethodContent(object innerContent) : base(innerContent) { this.Value = innerContent; } } ``` If a MethodFunction is returning an `IAsyncEnumerable` each enumerable result will be automatically wrapped in the `StreamingMethodContent` keeping the streaming behavior and the overall abstraction consistent. When a MethodFunction is not an `IAsyncEnumerable`, the complete result will be wrapped in a `StreamingMethodContent` and will be returned as a single item. ## Pros 1. All the User Experience Goal section options will be possible. 2. Kernel and Functions implementations will be able to stream data of any type, not limited to text 3. The sk developer will be able to provide the streaming content type it expects from the `GetStreamingContentAsync` method. 4. Sk developer will be able to get streaming from the Kernel, Functions and Connectors with the same result type. ## Cons 1. If the sk developer wants to use the specialized type of `StreamingContent` he will need to know what the connector is being used to use the correct **StreamingContent extension method** or to provide directly type in ``. 2. Connectors will have greater responsibility to support the correct special types of `StreamingContent`. ### Option 2 - Dedicated Streaming Interfaces (Returning a Class) All changes from option 1 with the small difference below: - The Kernel and SKFunction streaming APIs interfaces will return `StreamingFunctionResult` which also implements `IAsyncEnumerable` - Connectors streaming APIs interfaces will return `StreamingConnectorContent` which also implements `IAsyncEnumerable` The `StreamingConnectorContent` class is needed for connectors as one way to pass any information relative to the request and not the chunk that can be used by the functions to fill `StreamingFunctionResult` metadata. ## User Experience Goal Option 2 Biggest benefit: ```csharp // When the caller needs to know more about the streaming he can get the result reference before starting the streaming. var streamingResult = await kernel.RunStreamingAsync(function); // Do something with streamingResult properties // Consuming the streamingResult requires an extra await: await foreach(StreamingContent chunk content in await streamingResult) ``` Using the other operations will be quite similar (only needing an extra `await` to get the iterator) ```csharp // Getting a Raw Streaming data from Kernel await foreach(string update in await kernel.RunStreamingAsync(function, variables)) // Getting a String as Streaming data from Kernel await foreach(string update in await kernel.RunStreamingAsync(function, variables)) // Getting a StreamingContent as Streaming data from Kernel await foreach(StreamingContent update in await kernel.RunStreamingAsync(variables, function)) // OR await foreach(StreamingContent update in await kernel.RunStreamingAsync(function, variables)) // defaults to Generic above) { Console.WriteLine(update); } ``` StreamingConnectorResult is a class that can store information regarding the result before the stream is consumed as well as any underlying object (breaking glass) that the stream consumes at the connector level. ```csharp public sealed class StreamingConnectorResult : IAsyncEnumerable { private readonly IAsyncEnumerable _StreamingContentource; public object? InnerResult { get; private set; } = null; public StreamingConnectorResult(Func> streamingReference, object? innerConnectorResult) { this._StreamingContentource = streamingReference.Invoke(); this.InnerResult = innerConnectorResult; } } interface ITextCompletion + IChatCompletion { Task> GetStreamingContentAsync(); // Throw exception if T is not supported // Initially connectors } ``` StreamingFunctionResult is a class that can store information regarding the result before the stream is consumed as well as any underlying object (breaking glass) that the stream consumes from Kernel and SKFunctions. ```csharp public sealed class StreamingFunctionResult : IAsyncEnumerable { internal Dictionary? _metadata; private readonly IAsyncEnumerable _streamingResult; public string FunctionName { get; internal set; } public Dictionary Metadata { get; internal set; } /// /// Internal object reference. (Breaking glass). /// Each connector will have its own internal object representing the result. /// public object? InnerResult { get; private set; } = null; /// /// Instance of used by the function. /// internal SKContext Context { get; private set; } public StreamingFunctionResult(string functionName, SKContext context, Func> streamingResult, object? innerFunctionResult) { this.FunctionName = functionName; this.Context = context; this._streamingResult = streamingResult.Invoke(); this.InnerResult = innerFunctionResult; } } interface ISKFunction { // Extension generic method to get from type Task> InvokeStreamingAsync(...); } static class KernelExtensions { public static async Task> RunStreamingAsync(this Kernel kernel, ISKFunction skFunction, ContextVariables? variables, CancellationToken cancellationToken) { ... } } ``` ## Pros 1. All benefits from Option 1 + 2. Having StreamingFunctionResults allow sk developer to know more details about the result before consuming the stream, like: - Any metadata provided by the underlying API, - SKContext - Function Name and Details 3. Experience using the Streaming is quite similar (need an extra await to get the result) to option 1 4. APIs behave similarly to the non-streaming API (returning a result representation to get the value) ## Cons 1. All cons from Option 1 + 2. Added complexity as the IAsyncEnumerable cannot be passed directly in the method result demanding a delegate approach to be adapted inside of the Results that implements the IAsyncEnumerator. 3. Added complexity where IDisposable is needed to be implemented in the Results to dispose the response object and the caller would need to handle the disposal of the result. 4. As soon the caller gets a `StreamingFunctionResult` a network connection will be kept open until the caller implementation consume it (Enumerate over the `IAsyncEnumerable`). ## Decision Outcome Option 1 was chosen as the best option as small benefit of the Option 2 don't justify the complexity involved described in the Cons. Was also decided that the Metadata related to a connector backend response can be added to the `StreamingContent.Metadata` property. This will allow the sk developer to get the metadata even without a `StreamingConnectorResult` or `StreamingFunctionResult`. ================================================ FILE: docs/decisions/0024-connectors-api-equalization.md ================================================ ## Proposal ### IChatCompletion Before: ```csharp public interface IChatCompletion : IAIService { ChatHistory CreateNewChat(string? instructions = null); Task> GetChatCompletionsAsync(ChatHistory chat, ...); Task> GetChatCompletionsAsync(string prompt, ...); IAsyncEnumerable GetStreamingContentAsync(ChatHistory chatHistory, ...); } public static class ChatCompletionExtensions { public static async Task GenerateMessageAsync(ChatHistory chat, ...); } ``` After: ```csharp public interface IChatCompletion : IAIService { Task> GetChatContentsAsync(ChatHistory chat, ..> tags) IAsyncEnumerable GetStreamingChatContentsAsync(ChatHistory chatHistory, ...); } public static class ChatCompletionExtensions { // v Single vv Standardized Prompt (Parse tags) public static async Task GetChatContentAsync(string prompt, ...); // v Single public static async Task GetChatContentAsync(ChatHistory chatHistory, ...); public static IAsyncEnumerable GetStreamingChatContentsAsync(string prompt, ...); } ``` ### ITextCompletion Before: ```csharp public interface ITextCompletion : IAIService { Task> GetCompletionsAsync(string prompt, ...); IAsyncEnumerable GetStreamingContentAsync(string prompt, ...); } public static class TextCompletionExtensions { public static async Task CompleteAsync(string text, ...); public static IAsyncEnumerable GetStreamingContentAsync(string input, ...); } ``` After: ```csharp public interface ITextCompletion : IAIService { Task> GetTextContentsAsync(string prompt, ...); IAsyncEnumerable GetStreamingTextContentsAsync(string prompt, ...); } public static class TextCompletionExtensions { public static async Task GetTextContentAsync(string prompt, ...); } ``` ## Content Abstractions ### Model Comparisons #### Current Streaming Abstractions | Streaming (Current) | Specialized\* Streaming (Current) | | ------------------------------------------- | --------------------------------------------------------------- | | `StreamingChatContent` : `StreamingContent` | `OpenAIStreamingChatContent` | | `StreamingTextContent` : `StreamingContent` | `OpenAIStreamingTextContent`, `HuggingFaceStreamingTextContent` | #### Non-Streaming Abstractions (Before and After) | Non-Streaming (Before) | Non-Streaming (After) | Specialized\* Non-Streaming (After) | | ----------------------------- | ------------------------------ | --------------------------------------------- | | `IChatResult` : `IResultBase` | `ChatContent` : `ModelContent` | `OpenAIChatContent` | | `ITextResult` : `IResultBase` | `TextContent` : `ModelContent` | `OpenAITextContent`, `HuggingFaceTextContent` | | `ChatMessage` | `ChatContent` : `ModelContent` | `OpenAIChatContent` | _\*Specialized: Connector implementations that are specific to a single AI Service._ ### New Non-Streaming Abstractions: `ModelContent` was chosen to represent a `non-streaming content` top-most abstraction which can be specialized and contains all the information that the AI Service returned. (Metadata, Raw Content, etc.) ```csharp /// /// Base class for all AI non-streaming results /// public abstract class ModelContent { /// /// Raw content object reference. (Breaking glass). /// public object? InnerContent { get; } /// /// The metadata associated with the content. /// ⚠️ (Token Usage + More Backend API Metadata) info will be in this dictionary.

We should update current implementation of `ChatMessageContent` class with `string Content` property to support this API. ## Decision Drivers 1. New design should not be coupled to OpenAI API and should work for other AI providers. 2. Naming of classes and properties should be consistent and intuitive. ## Considered Options Some of the option variations can be combined. ### Option #1: Naming updates and new data type for `chat message content` Since `chat message content` can be an object now instead of `string`, it requires reserved name for better understanding in domain. 1. `ChatMessageContent` will be renamed to `ChatMessage`. (Same for `StreamingChatMessageContent`). 2. `GetChatMessageContent` methods will be renamed to `GetChatMessage`. 3. New abstract class `ChatMessageContent` that will have property `ChatMessageContentType Type` with values `text`, `image`. (Will be extended with `audio`, `video` in the future). 4. `ChatMessage` will contain collection of `ChatMessageContent` objects `IList Contents`. 5. There will be concrete implementations of `ChatMessageContent` - `ChatMessageTextContent` and `ChatMessageImageContent`. New _ChatMessageContentType.cs_ ```csharp public readonly struct ChatMessageContentType : IEquatable { public static ChatMessageContentType Text { get; } = new("text"); public static ChatMessageContentType Image { get; } = new("image"); public string Label { get; } // Implementation of `IEquatable`... } ``` New _ChatMessageContent.cs_ ```csharp public abstract class ChatMessageContent { public ChatMessageContentType Type { get; set; } public ChatMessageContent(ChatMessageContentType type) { this.Type = type; } } ``` Updated _ChatMessage.cs_: ```csharp public class ChatMessage : ContentBase { public AuthorRole Role { get; set; } public IList Contents { get; set; } ``` New _ChatMessageTextContent.cs_ ```csharp public class ChatMessageTextContent : ChatMessageContent { public string Text { get; set; } public ChatMessageTextContent(string text) : base(ChatMessageContentType.Text) { this.Text = text; } } ``` New _ChatMessageImageContent.cs_ ```csharp public class ChatMessageImageContent : ChatMessageContent { public Uri Uri { get; set; } public ChatMessageImageContent(Uri uri) : base(ChatMessageContentType.Image) { this.Uri = uri; } } ``` Usage: ```csharp var chatHistory = new ChatHistory("You are friendly assistant."); // Construct request var userContents = new List { new ChatMessageTextContent("What's in this image?"), new ChatMessageImageContent(new Uri("https://link-to-image.com")) }; chatHistory.AddUserMessage(userContents); // Get response var message = await chatCompletionService.GetChatMessageAsync(chatHistory); foreach (var content in message.Contents) { // Possibility to get content type (text or image). var contentType = content.Type; // Cast for specific content type // Extension methods can be provided for better usability // (e.g. message GetContent()). if (content is ChatMessageTextContent textContent) { Console.WriteLine(textContent); } if (content is ChatMessageImageContent imageContent) { Console.WriteLine(imageContent.Uri); } } ``` ### Option #2: Avoid renaming and new data type for `chat message content` Same as Option #1, but without naming changes. In order to differentiate actual `chat message` and `chat message content`: - `Chat Message` will be `ChatMessageContent` (as it is right now). - `Chat Message Content` will be `ChatMessageContentItem`. 1. New abstract class `ChatMessageContentItem` that will have property `ChatMessageContentItemType Type` with values `text`, `image`. (Will be extended with `audio`, `video` in the future). 2. `ChatMessageContent` will contain collection of `ChatMessageContentItem` objects `IList Items`. 3. There will be concrete implementations of `ChatMessageContentItem` - `ChatMessageTextContentItem` and `ChatMessageImageContentItem`. New _ChatMessageContentItemType.cs_ ```csharp public readonly struct ChatMessageContentItemType : IEquatable { public static ChatMessageContentItemType Text { get; } = new("text"); public static ChatMessageContentItemType Image { get; } = new("image"); public string Label { get; } // Implementation of `IEquatable`... } ``` New _ChatMessageContentItem.cs_ ```csharp public abstract class ChatMessageContentItem { public ChatMessageContentItemType Type { get; set; } public ChatMessageContentItem(ChatMessageContentItemType type) { this.Type = type; } } ``` Updated _ChatMessageContent.cs_: ```csharp public class ChatMessageContent : ContentBase { public AuthorRole Role { get; set; } public IList Items { get; set; } ``` New _ChatMessageTextContentItem.cs_ ```csharp public class ChatMessageTextContentItem : ChatMessageContentItem { public string Text { get; set; } public ChatMessageTextContentItem(string text) : base(ChatMessageContentType.Text) { this.Text = text; } } ``` New _ChatMessageImageContent.cs_ ```csharp public class ChatMessageImageContentItem : ChatMessageContentItem { public Uri Uri { get; set; } public ChatMessageImageContentItem(Uri uri) : base(ChatMessageContentType.Image) { this.Uri = uri; } } ``` Usage: ```csharp var chatHistory = new ChatHistory("You are friendly assistant."); // Construct request var userContentItems = new List { new ChatMessageTextContentItem("What's in this image?"), new ChatMessageImageContentItem(new Uri("https://link-to-image.com")) }; chatHistory.AddUserMessage(userContentItems); // Get response var message = await chatCompletionService.GetChatMessageContentAsync(chatHistory); foreach (var contentItem in message.Items) { // Possibility to get content type (text or image). var contentItemType = contentItem.Type; // Cast for specific content type // Extension methods can be provided for better usability // (e.g. message GetContent()). if (contentItem is ChatMessageTextContentItem textContentItem) { Console.WriteLine(textContentItem); } if (contentItem is ChatMessageImageContentItem imageContentItem) { Console.WriteLine(imageContentItem.Uri); } } ``` ### Option #3: Add new property to `ChatMessageContent` - collection of content items This option will keep `string Content` property as it is, but will add new property - collection of `ContentBase` items. Updated _ChatMessageContent.cs_ ```csharp public class ChatMessageContent : ContentBase { public AuthorRole Role { get; set; } public string? Content { get; set; } public ChatMessageContentItemCollection? Items { get; set; } } ``` New _ChatMessageContentItemCollection.cs_ ```csharp public class ChatMessageContentItemCollection : IList, IReadOnlyList { // Implementation of IList, IReadOnlyList to catch null values. } ``` Usage: ```csharp var chatCompletionService = kernel.GetRequiredService(); var chatHistory = new ChatHistory("You are a friendly assistant."); chatHistory.AddUserMessage(new ChatMessageContentItemCollection { new TextContent("What’s in this image?"), new ImageContent(new Uri(ImageUri)) }); var reply = await chatCompletionService.GetChatMessageContentAsync(chatHistory); Console.WriteLine(reply.Content); ``` ## Decision Outcome Option #3 was preferred as it requires small amount of changes to existing hierarchy and provides clean usability for end-user. Diagram: ![Chat and Text models diagram](diagrams/chat-text-models.png) ================================================ FILE: docs/decisions/0025-planner-telemetry-enhancement.md ================================================ --- status: { accepted } contact: { TaoChenOSU } date: { 2023-11-21 } deciders: alliscode, dmytrostruk, markwallace, SergeyMenshykh, stephentoub consulted: {} informed: {} --- # Planner Telemetry Enhancement ## Context and Problem Statement It would be extremely beneficial for applications using Semantic Kernel's planning features to be able to continuously monitor the performance of planners and plans as well as debugging them. ## Scenarios Contoso is a company that is developing an AI application using SK. 1. Contoso needs to continuously monitor the token usage of a particular planner, including prompt tokens, completion tokens, and the total tokens. 2. Contoso needs to continuously monitor the time it takes for a particular planner to create a plan. 3. Contoso needs to continuously monitor the success rate of a particular planner in creating a valid plan. 4. Contoso needs to continuously monitor the success rate of a particular plan type being executed successfully. 5. Contoso wants to be able to see the token usage of a particular planner run. 6. Contoso wants to be able to see the time taken to create a plan of a particular planner run. 7. Contoso wants to be able to see the steps in a plan. 8. Contoso wants to be able to see the inputs&outputs of each plan step. 9. Contoso wants to change a few settings that may affect the performance of the planners. They would like to know how the performance will be affected before committing the changes. 10. Contoso wants to update to a new model that is cheaper and faster. They would like to know how the new model performs in planning tasks. ## Out of scope 1. We provide an example on how to send telemetry to Application Insights. Although other telemetry service options are supported technically, we will not cover possible ways of setting them up in this ADR. 2. This ADR does not seek to modify the current instrumentation design in SK. 3. We do not consider services that do not return token usage. ## Decision Drivers - The framework should be telemetry service agnostic. - The following metrics should be emitted by SK: - Input token usage for prompt (Prompt) - Description: A prompt is the smallest unit that consumes tokens (`KernelFunctionFromPrompt`). - Dimensions: ComponentType, ComponentName, Service ID, Model ID - Type: Histogram - Example: | ComponentType | ComponentName | Service ID | Model ID | Value | |---|---|---|---|---| | Function | WritePoem | | GPT-3.5-Turbo | 40 | Function | TellJoke | | GPT-4 | 50 | Function | WriteAndTellJoke | | GPT-3.5-Turbo | 30 | Planner | CreateHandlebarsPlan | | GPT-3.5-Turbo | 100 - Output token usage for prompt (Completion) - Description: A prompt is the smallest unit that consumes tokens (`KernelFunctionFromPrompt`). - Dimensions: ComponentType, ComponentName, Service ID, Model ID - Type: Histogram - Example: | ComponentType | ComponentName | Service ID | Model ID | Value | |---|---|---|---|---| | Function | WritePoem | | GPT-3.5-Turbo | 40 | Function | TellJoke | | GPT-4 | 50 | Function | WriteAndTellJoke | | GPT-3.5-Turbo | 30 | Planner | CreateHandlebarsPlan | | GPT-3.5-Turbo | 100 - Aggregated execution time for functions - Description: A function can consist of zero or more prompts. The execution time of a function is the duration from start to end of a function's `invoke` call. - Dimensions: ComponentType, ComponentName, Service ID, Model ID - Type: Histogram - Example: | ComponentType | ComponentName | Value | |---|---|---| | Function | WritePoem | 1m | Function | TellJoke | 1m | Function | WriteAndTellJoke | 1.5m | Planner | CreateHandlebarsPlan | 2m - Success/failure count for planners - Description: A planner run is considered successful when it generates a valid plan. A plan is valid when the model response is successfully parsed into a plan of desired format and it contains one or more steps. - Dimensions: ComponentType, ComponentName, Service ID, Model ID - Type: Counter - Example: | ComponentType | ComponentName | Fail | Success |---|---|---|---| | Planner | CreateHandlebarsPlan | 5 | 95 | Planner | CreateHSequentialPlan | 20 | 80 - Success/failure count for plans - Description: A plan execution is considered successful when all steps in the plan are executed successfully. - Dimensions: ComponentType, ComponentName, Service ID, Model ID - Type: Counter - Example: | ComponentType | ComponentName | Fail | Success |---|---|---|---| | Plan | HandlebarsPlan | 5 | 95 | Plan | SequentialPlan | 20 | 80 ## Considered Options - Function hooks - Inject logic to functions that will get executed before or after a function is invoked. - Instrumentation - Logging - Metrics - Traces ## Other Considerations SK currently tracks token usage metrics in connectors; however, these metrics are not categorized. Consequently, developers cannot determine token usage for different operations. To address this issue, we propose the following two approaches: - Bottom-up: Propagate token usage information from connectors back to the functions. - Top-down: Propagate function information down to the connectors, enabling them to tag metric items with function information. We have decided to implement the bottom-up approach for the following reasons: 1. SK is already configured to propagate token usage information from connectors via `ContentBase`. We simply need to extend the list of items that need to be propagated, such as model information. 2. Currently, SK does not have a method for passing function information down to the connector level. Although we considered using [baggage](https://opentelemetry.io/docs/concepts/signals/baggage/#:~:text=In%20OpenTelemetry%2C%20Baggage%20is%20contextual%20information%20that%E2%80%99s%20passed,available%20to%20any%20span%20created%20within%20that%20trace.) as a means of propagating information downward, experts from the OpenTelemetry team advised against this approach due to security concerns. With the bottom-up approach, we need to retrieve the token usage information from the metadata: ```csharp // Note that not all services support usage details. /// /// Captures usage details, including token information. /// private void CaptureUsageDetails(string? modelId, IDictionary? metadata, ILogger logger) { if (string.IsNullOrWhiteSpace(modelId)) { logger.LogWarning("No model ID provided to capture usage details."); return; } if (metadata is null) { logger.LogWarning("No metadata provided to capture usage details."); return; } if (!metadata.TryGetValue("Usage", out object? usageObject) || usageObject is null) { logger.LogWarning("No usage details provided to capture usage details."); return; } var promptTokens = 0; var completionTokens = 0; try { var jsonObject = JsonElement.Parse(JsonSerializer.Serialize(usageObject)); promptTokens = jsonObject.GetProperty("PromptTokens").GetInt32(); completionTokens = jsonObject.GetProperty("CompletionTokens").GetInt32(); } catch (Exception ex) when (ex is KeyNotFoundException) { logger.LogInformation("Usage details not found in model result."); } catch (Exception ex) { logger.LogError(ex, "Error while parsing usage details from model result."); throw; } logger.LogInformation( "Prompt tokens: {PromptTokens}. Completion tokens: {CompletionTokens}.", promptTokens, completionTokens); TagList tags = new() { { "semantic_kernel.function.name", this.Name }, { "semantic_kernel.function.model_id", modelId } }; s_invocationTokenUsagePrompt.Record(promptTokens, in tags); s_invocationTokenUsageCompletion.Record(completionTokens, in tags); } ``` > Note that we do not consider services that do not return token usage. Currently only OpenAI & Azure OpenAI services return token usage information. ## Decision Outcome 1. New metrics names: | Meter | Metrics | |---|---| |Microsoft.SemanticKernel.Planning|
  • semantic_kernel.planning.invoke_plan.duration
| |Microsoft.SemanticKernel|
  • semantic_kernel.function.invocation.token_usage.prompt
  • semantic_kernel.function.invocation.token_usage.completion
| > Note: we are also replacing the "sk" prefixes with "semantic_kernel" for all existing metrics to avoid ambiguity. 2. Instrumentation ## Validation Tests can be added to make sure that all the expected telemetry items are in place and of the correct format. ## Description the Options ### Function hooks Function hooks allow developers to inject logic to the kernel that will be executed before or after a function is invoked. Example use cases include logging the function input before a function is invoked, and logging results after the function returns. For more information, please refer to the following ADRs: 1. [Kernel Hooks Phase 1](./0005-kernel-hooks-phase1.md) 2. [Kernel Hooks Phase 2](./0018-kernel-hooks-phase2.md) We can inject, during function registration, default callbacks to log critical information for all functions. Pros: 1. Maximum exposure and flexibility to the developers. i.e. App developers can very easily log additional information for individual functions by adding more callbacks. Cons: 1. Does not create metrics and need additional works to aggregate results. 2. Relying only on logs does not provide trace details. 3. Logs are modified more frequently, which could lead an unstable implementation and require extra maintenance. 4. Hooks only have access to limited function data. > Note: with distributed tracing already implemented in SK, developers can create custom telemetry within the hooks, which will be sent to the telemetry service once configured, as long as the information is available in the hooks. However, telemetry items created inside the hooks will not be correlated to the functions as parent-child relationships, since they are outside the scope of the functions. ### Distributed tracing Distributed tracing is a diagnostic technique that can localize failures and performance bottlenecks within distributed applications. .Net has native support to add distributed tracing in libraries and .Net libraries are also instrumented to produce distributed tracing information automatically. For more information, please refer to this document: [.Net distributed tracing](https://learn.microsoft.com/en-us/dotnet/core/diagnostics/) Overall pros: 1. Native .Net support. 2. Distributed tracing is already implemented in SK. We just need to add more telemetry. 3. Telemetry service agnostic with [OpenTelemetry](https://opentelemetry.io/docs/what-is-opentelemetry/). Overall cons: 1. Less flexibility for app developers consuming SK as a library to add custom traces and metrics. #### Logging Logs will be used to record interesting events while the code is running. ```csharp // Use LoggerMessage attribute for optimal performance this._logger.LogPlanCreationStarted(); this._logger.LogPlanCreated(); ``` #### [Metrics](https://learn.microsoft.com/en-us/dotnet/core/diagnostics/metrics) Metrics will be used to record measurements overtime. ```csharp /// for function-related metrics. private static readonly Meter s_meter = new("Microsoft.SemanticKernel"); /// to record plan execution duration. private static readonly Histogram s_planExecutionDuration = s_meter.CreateHistogram( name: "semantic_kernel.planning.invoke_plan.duration", unit: "s", description: "Duration time of plan execution."); TagList tags = new() { { "semantic_kernel.plan.name", planName } }; try { ... } catch (Exception ex) { // If a measurement is tagged with "error.type", then it's a failure. tags.Add("error.type", ex.GetType().FullName); } s_planExecutionDuration.Record(duration.TotalSeconds, in tags); ``` #### [Traces](https://learn.microsoft.com/en-us/dotnet/core/diagnostics/distributed-tracing) Activities are used to track dependencies through an application, correlating work done by other components, and form a tree of activities known as a trace. ```csharp ActivitySource s_activitySource = new("Microsoft.SemanticKernel"); // Create and start an activity using var activity = s_activitySource.StartActivity(this.Name); // Use LoggerMessage attribute for optimal performance logger.LoggerGoal(goal); logger.LoggerPlan(plan); ``` > Note: Trace log will contain sensitive data and should be turned off in production: https://learn.microsoft.com/en-us/dotnet/core/extensions/logging?tabs=command-line#log-level ## Example of how an application would send the telemetry to Application Insights ```csharp using var traceProvider = Sdk.CreateTracerProviderBuilder() .AddSource("Microsoft.SemanticKernel*") .AddAzureMonitorTraceExporter(options => options.ConnectionString = connectionString) .Build(); using var meterProvider = Sdk.CreateMeterProviderBuilder() .AddMeter("Microsoft.SemanticKernel*") .AddAzureMonitorMetricExporter(options => options.ConnectionString = connectionString) .Build(); using var loggerFactory = LoggerFactory.Create(builder => { // Add OpenTelemetry as a logging provider builder.AddOpenTelemetry(options => { options.AddAzureMonitorLogExporter(options => options.ConnectionString = connectionString); // Format log messages. This is default to false. options.IncludeFormattedMessage = true; }); builder.SetMinimumLevel(MinLogLevel); }); ``` ## More information Additional works that need to be done: 1.

However, we will only focus on the two most widely-used ones: GitHub Flow and Git-Flow. ### GitHub Flow GitHub Flow is a straightforward branching strategy that centres around the 'main' branch. Developers create a new branch for each feature or bugfix, make changes, submit a pull request, and merge the changes back to the 'main' branch. Releases are done directly from the 'main' branch, making this model ideal for projects with continuous integration/deployment. Learn more about [GitHub Flow](https://docs.github.com/en/get-started/quickstart/github-flow). GitFlow [Image source](https://www.abtasty.com/blog/git-branching-strategies/) Pros: - Straightforward with fewer branches to manage and less merge conflicts. - No long running development branches. Cons: - Not as well organized as Git-Flow. - The 'main' branch can get cluttered more easily since it functions as both the production and development branch. ### Git-Flow Git-Flow is a branching strategy that organizes software development around two long-lived main branches, 'main' and 'develop', along with short-lived feature, release, and hotfix branches. Developers work on new features in feature branches, which are then merged into the 'develop' branch. When preparing for a release, to avoid blocking future release features, a release branch is created, and once finalized (testing & bug fixing), it is merged into both 'main' and 'develop'. Hotfix branches in Git Flow are created from the 'main' branch to address critical bug fixes and are subsequently merged back into both the 'main' and 'develop' branches. The actual release(deployable artifact) is done from the 'main' branch that is reflects actual production worthy official releases. Learn more about [Git-Flow](https://nvie.com/posts/a-successful-git-branching-model/). GitFlow Pros: - Clear separation between code under development and production-ready code. - Efficient release management. Cons: - More complex than GitHub Flow, which may be overwhelming for smaller teams or projects that do not require as much structure. - Less suited for projects that prioritize continuous deployment, as it emphasizes a more controlled release process. - Not ideal for projects with continuous deployment due to the overhead of managing multiple branches. - Spaghetti history in Git - [GitFlow considered harmful](https://www.endoflineblog.com/gitflow-considered-harmful) # SK branching strategies Today, the SK SDK is available in three languages: .NET, Java and Python. All of them coexist in the same Git repository, organized under corresponding folders. However, the branching strategies for those differ. For both .NET and Python versions, development takes place in short-lived topic branches that branch off the 'main' branch. These topic branches are merged back into the 'main' branch when features are considered production-ready through PR reviews, unit tests, and integration test runs. Releases are carried out directly from the 'main' branch. This approach aligns with the GitHub Flow branching strategy, with a minor deviation where releases are conducted weekly rather than being continuously deployed. The Java version of SK adheres to the Git-Flow strategy by being developed in a dedicated development branch. Topic branches are created from the development branch and merged back through pull requests after unit tests and integration test runs. Release branches are also created from the development branch and merged to both the development branch and the 'main' one when a release is considered production-ready. This strategy deviates slightly from vanilla Git-Flow in that release artifacts are generated from release branches rather than from the 'main' branch. ## Decision Drivers - The strategy should be easy to implement and maintain without requiring significant investments. - The strategy should allow for maintaining several releases in parallel if required. - Ideally, the strategy is intuitive and simple so that everyone familiar with Git can adopt and follow it. - Ideally, all SK languages are able to adopt and use the same branching strategy. - Ability to continually deploy new release with minimal overhead. - Ability to release language versions independently and on different schedules. - Allow the .Net, Java and Python teams to be able to operate independently. - Ability to patch a release (for all languages). - Consolidation of PR's and Issues to simplify the triage and review process. Another aspect to consider when deciding on a branching strategy for SK is access permissions and action scopes. GitHub does not allow enforcing access restrictions on just a part of a repository, such as a folder. This means that it is not possible to restrict SK .NET contributors from pushing Python PRs, which ideally should be done by the corresponding team. However, GitHub does allow assigning access permissions to a branch, which can be successfully leveraged if the appropriate strategy option is chosen. The similar issue occurs with GitHub's required actions/status checks, which can only be set at the branch level. Considering that development for .NET and Python takes place in the 'main' branch, and status checks are configured per branch rather than per folder, it is not possible to configure separate status checks for .NET and Python PRs. As a result, the same status check runs for both .NET and Python PRs, even though it may not be relevant to a specific language. !["Net PR status checks"](./diagrams/net-pr-status-checks.png) Regardless of the chosen strategy, it should be possible to support multiple versions of SK. For example, applying a bug fix or a security patch to released SK v1.1.0 and v2.4.0 should be feasible while working on v3.0.0. One way to achieve this would be to create a release branch for each SK release. So that the required patch/fix can be pushed to the branch and released from it. However, marking released commits with tags should suffice, as it is always possible to create a new branch from a tag retrospectively when needed, if at all. Existing release pipelines should accept a source branch as a parameter, enabling releases from any branch and not only from the 'main' one. ## Considered Options ### Repository per SK language This option suggests having a separate GitHub repository for each SK language. These repositories can be created under a corresponding organization. Development and releases will follow the GitHub flow, with new features and fixes being developed in topic branches that created from the 'main' branch and eventually merged back. Pros: - Each repository will have only language-specific status checks and actions. - Branch commits and release history will not contain irrelevant commits or releases. - Utilizes the familiar GitHub Flow without Git-Flow overhead, resulting in a shorter learning curve. - Access permissions are limited to the specific owning team. Cons: - There is an initial overhead in setting up the three repositories. - There may be potential ongoing maintenance overhead for the three repositories. - Secrets must be managed across three repositories instead of just one. - Each repo will have a backlog that will have to be managed separately. ### Branch per SK language This option involves having a dedicated, language-specific development branch for each SDK language: 'net-development', 'java-development', and 'python-development'. SDK Java is already using this option. Development and releases will follow the GitHub Flow, with new features and fixes being developed in topic branches that are branched off the corresponding language branch and eventually merged back. Pros: - Simple, language specific, status checks, actions and rules configured per language branch. - Allow only teams that own language-specific branches to push or merge to them, rather than just approving PRs. - Branch commits history does not contain irrelevant commits. Cons: - GitHub release history contains releases for all languages. - Language-specific branches may not be straightforward to discover/use. This option has two sub-options that define the way the 'main' branch is used: 1. The 'main' branch will contain general/common artifacts such as documentation, GitHub actions, and samples. All language folders will be removed from the 'main' branch, and it can be locked to prevent accidental merges. 2. The 'main' branch will include everything that dev branches have for discoverability purposes. A job/action will be implemented to merge commits from dev branches to the 'main' branch. The number of common artifacts between SK languages should be minimized to reduce the potential for merge conflicts. A solution for the squash merge problem that SK Java is experiencing today should be found before deciding on the sub-option. The second sub-option is preferred over the first one due to its discoverability benefits. There is no need to select a development branch in the GitHub UI when searching for something in the repository. The 'main' branch is selected by default, and as soon as the latest bits are in the branch, they can be found easily. This intuitive approach is familiar to many, and changing it by requiring the selection of a branch before searching would complicate the search experience and introduce frustration. ### All SK languages in the 'main' This option assumes maintaining the code for all SK languages - .NET, Java, and Python in the 'main' branch. Development would occur using typical topic branches, while releases would also be made from the 'main' branch. This is the strategy currently adopted by .NET and Python, and corresponds to the GitHub Flow. Pros: - All code in one place - the 'main' branch. - Familiar GitHub Flow, no Git-Flow overhead - shorter learning curve. Cons: - Branch commits/release history contains irrelevant commits/releases. - Complex and irrelevant GitHub status checks/actions. - PRs can be pushed by non-owner teams. ### Current 'Hybrid' approach This choice keeps the existing method used by SK. .NET and Python development is done in the 'main' branch using GitHub Flow, while Java development happens in the java-development branch following Git-Flow. Pros: - No changes required. - Each SK language uses a strategy that is convenient for it. Cons: - Branch commits/release history contains irrelevant commits/releases. - Complex and irrelevant GitHub status checks/actions. - PRs can be pushed by non-owner teams. ## Decision Outcome Chosen option: "Current 'Hybrid' approach" because it works with minor inefficiencies (such as cluttered release history and multi-language complex actions) and requires no investments now. Later, depending on the team size and the problems the team encounters with the "Current 'Hybrid' approach," we may consider either the 'Repository per SK language' option or the 'Branch per SK language' one. ================================================ FILE: docs/decisions/0031-feature-branch-strategy.md ================================================ --- # Strategy for Community Driven Connectors and Features status: approved contact: rogerbarreto date: 2024-01-24 deciders: rogerbarreto, markwallace-microsoft, dmytrostruk, sergeymenshik consulted: informed: --- # Strategy for Community Driven Connectors and Features ## Context and Problem Statement Normally Connectors are Middle to Complex new Features that can be developed by a single person or a team. In order to avoid conflicts and to have a better control of the development process, we strongly suggest the usage of a Feature Branch Strategy in our repositories. In our current software development process, managing changes in the main branch has become increasingly complex, leading to potential conflicts and delays in release cycles. ## Standards and Guidelines Principles - **Pattern**: The Feature Branch Strategy is a well-known pattern for managing changes in a codebase. It is widely used in the industry and is supported by most version control systems, including GitHub, this also gives further clear picture on how the community can meaningfully contribute to the development of connectors or any other bigger feature for SK. - **Isolated Development Environments**: By using feature branches, each developer can work on different aspects of the project without interfering with others' work. This isolation reduces conflicts and ensures that the main branch remains stable. - **Streamlined Integration**: Feature branches simplify the process of integrating new code into the main branch. By dealing with smaller, more manageable changes, the risk of major conflicts during integration is minimized. - **Efficiency in Code Review**: Smaller, more focused changes in feature branches lead to quicker and more efficient code reviews. This efficiency is not just about the ease of reviewing less code at a time but also about the time saved in understanding the context and impact of the changes. - **Reduced Risk of Bugs**: Isolating development in feature branches reduces the likelihood of introducing bugs into the main branch. It's easier to identify and fix issues within the confined context of a single feature. - **Timely Feature Integration**: Small, incremental pull requests allow for quicker reviews and faster integration of features into the feature branch and make it easier to merge down into main as the code was already previously reviewed. This timeliness ensures that features are merged and ready for deployment sooner, improving the responsiveness to changes. - **Code Testing, Coverage and Quality**: To keep a good code quality is imperative that any new code or feature introduced to the codebase is properly tested and validated. Any new feature or code should be covered by unit tests and integration tests. The code should also be validated by our CI/CD pipeline and follow our code quality standards and guidelines. - **Examples**: Any new feature or code should be accompanied by examples that demonstrate how to use the new feature or code. This is important to ensure that the new feature or code is properly documented and that the community can easily understand and use it. - **Signing**: Any connector that will eventually become a package needs to have the package and the assembly signing enabled (Set to Publish = Publish) in the `SK-dotnet.sln` file. ``` {Project GUID}.Publish|Any CPU.ActiveCfg = Publish|Any CPU {Project GUID}.Publish|Any CPU.Build.0 = Publish|Any CPU ``` ### Community Feature Branch Strategy As soon we identify that contributors are willing to take/create a Feature Issue as a potential connector implementation, we will create a new branch for that feature. Once we have agreed to take a new connector we will work with the contributors to make sure the implementation progresses and is supported if needed. The contributor(s) will then be one of the responsibles to incrementally add the majority of changes through small Pull Requests to the feature branch under our supervision and review process. This strategy involves creating a separate branch in the repository for each new big feature, like connectors. This isolation means that changes are made in a controlled environment without affecting the main branch. We may also engage in the development and changes to the feature branch when needed, the changes and full or co-authorship on the PRs will be tracked and properly referred into the Release Notes. #### Pros and Cons - Good, because it allows for focused development on one feature at a time. - Good, because it promotes smaller, incremental Pull Requests (PRs), simplifying review processes. - Good, because it reduces the risk of major bugs being merged into the main branch. - Good, because it makes the process of integrating features into the main branch easier and faster. - Bad, potentially, if not managed properly, as it can lead to outdated branches if not regularly synchronized with the main branch. ## Local Deployment Platforms / Offline ### LM Studio LM Studio has a local deployment option, which can be used to deploy models locally. This option is available for Windows, Linux, and MacOS. Pros: - API is very similar to OpenAI API - Many models are already supported - Easy to use - Easy to deploy - GPU support Cons: - May require a license to use in a work environment ### Ollama Ollama has a local deployment option, which can be used to deploy models locally. This option is available for Linux and MacOS only for now. Pros: - Easy to use - Easy to deploy - Supports Docker deployment - GPU support Cons: - API is not similar to OpenAI API (Needs a dedicated connector) - Dont have Windows support ### Comparison | Feature | Ollama | LM Studio | | --------------------- | --------------------------------------------------- | --------------------------------------------------------------------------------------- | | Local LLM | Yes | Yes | | OpenAI API Similarity | Yes | Yes | | Windows Support | No | Yes | | Linux Support | Yes | Yes | | MacOS Support | Yes | Yes | | Number of Models | [61](https://ollama.com/search) +Any GGUF converted | [25](https://github.com/lmstudio-ai/model-catalog/tree/main/models) +Any GGUF Converted | | Model Support | Ollama | LM Studio | | --------------- | ------ | --------- | | Phi-2 Support | Yes | Yes | | Llama-2 Support | Yes | Yes | | Mistral Support | Yes | Yes | ## Connector/Model Priorities Currently we are looking for community support on the following models The support on the below can be either achieved creating a practical example using one of the existing Connectors against one of this models or providing a new Connector that supports a deployment platform that hosts one of the models below: | Model Name | Local Support | Deployment | Connectors | | ---------- | ------------- | -------------------------------------- | ------------------------------------------------------ | | Gpt-4 | No | OpenAI, Azure | Azure+OpenAI | | Phi-2 | Yes | Azure, Hugging Face, LM Studio, Ollama | OpenAI, HuggingFace, LM Studio\*\*\*, Ollama\*\* | | Gemini | No | Google AI Platform | GoogleAI\*\* | | Llama-2 | Yes | Azure, LM Studio, HuggingFace, Ollama | HuggingFace, Azure+OpenAI, LM Studio\*\*\*, Ollama\*\* | | Mistral | Yes | Azure, LM Studio, HuggingFace, Ollama | HuggingFace, Azure+OpenAI, LM Studio\*\*\*, Ollama\*\* | | Claude | No | Anthropic, Amazon Bedrock | Anthropic**, Amazon** | | Titan | No | Amazon Bedrock | Amazon\*\* | _\*\* Connectors not yet available_ _\*\*\* May not be needed as an OpenAI Connector can be used_ Connectors may be needed not per Model basis but rather per deployment platform. For example, using OpenAI or HuggingFace connector you may be able to call a Phi-2 Model. ## Expected Connectors to be implemented The following deployment platforms are not yet supported by any Connectors and we strongly encourage the community to engage and support on those: Currently the priorities are ordered but not necessarily needs to be implemented sequentially, an | Deployment Platform | Local Model Support | | ------------------- | ------------------- | | Ollama | Yes | | GoogleAI | No | | Anthropic | No | | Amazon | No | ## Decision Outcome Chosen option: "Feature Branch Strategy", because it allows individual features to be developed in isolation, minimizing conflicts with the main branch and facilitating easier code reviews. ## Fequent Asked Questions ### Is there a migration strategy for initiatives that followed the old contribution way with forks, and now have to switch to branches in microsoft/semantic-kernel? You proceed normally with the fork and PR targeting `main`, as soon we identify that your contribution PR to main is a big and desirable feature (Look at the ones we described as expected in this ADR) we will create a dedicated feature branch (`feature-yourfeature`) where you can retarget our forks PR to target it. All further incremental changes and contributions will follow as normal, but instead of `main` you will be targeting the `feature-*` branch. ### How do you want to solve the "up to date with main branch" problem? This will happen when we all agreed that the current feature implementation is complete and ready to merge in `main`. As soon the feature is finished, a merge from main will be pushed into the feature branch. This will normally trigger the conflicts that need to be sorted. That normally will be the last PR targeting the feature branch which will be followed right away by another PR from the `feature` branch targeting `main` with minimal conflicts if any. The merging to main might be fast (as all the intermediate feature PRs were all agreed and approved before) ### Merging main branch to feature branch before finish feature The merging of the main branch into the feature branch should only be done with the command: `git checkout && git merge main` without --squash Merge from the main should never be done by PR to feature branch, it will cause merging history of main merge with history of PR (because PR are merged with --squash), and as a consequence it will generate strange conflicts on subsequent merges of main and also make it difficult to analyze history of feature branch. ================================================ FILE: docs/decisions/0032-agents.md ================================================ --- # These are optional elements. Feel free to remove any of them. status: experimental contact: crickman date: 2024-01-24 deciders: markwallace-microsoft, matthewbolanos consulted: rogerbarreto, dmytrostruk, alliscode, SergeyMenshykh informed: --- # SK Agents Overview and High Level Design ## **Context and Problem Statement** Support for the OpenAI Assistant API was published in an experimental `*.Assistants` package that was later renamed to `*.Agents` with the aspiration of pivoting to a more general agent framework. The initial `Assistants` work was never intended to evolve into a general _Agent Framework_. This ADR defines that general _Agent Framework_. An agent is expected to be able to support two interaction patterns: 1. **Direct Invocation ("No Chat"):** The caller is able to directly invoke any single agent without any intervening machinery or infrastructure. For different agents to take turns in a conversation using direct invocation, the caller is expected to invoke each agent per turn. Coordinating interaction between different agent types must also be explicitly managed by the caller. 2. **Agent Chat:** The caller is able to assemble multiple agents to participate in an extended conversation for the purpose of accomplishing a specific goal (generally in response to initial or iterative input). Once engaged, agents may participate in the chat over multiple interactions by taking turns. ## **Agents Overview** Fundamentally an agent possesses the following characteristics: - Identity: Allows each agent to be uniquely identified. - Behavior: The manner in which an agent participates in a conversation - Interaction: That an agent behavior is in response to other agents or input. Various agents specializations might include: - System Instructions: A set of directives that guide the agent's behavior. - Tools/Functions: Enables the agent to perform specific tasks or actions. - Settings: Agent specific settings. For chat-completion agents this might include LLM settings - such as Temperature, TopP, StopSequence, etc ### **Agent Modalities** An _Agent_ can be of various modalities. Modalities are asymmetrical with regard to abilities and constraints. - **SemanticKernel - ChatCompletion**: An _Agent_ based solely on the *SemanticKernel* support for chat-completion (e.g. .NET `ChatCompletionService`). - **OpenAI Assistants**: A hosted _Agent_ solution supported the _OpenAI Assistant API_ (both OpenAI & Azure OpenAI). - **Custom**: A custom agent developed by extending the _Agent Framework_. - **Future**: Yet to be announced, such as a HuggingFace Assistant API (they already have assistants, but yet to publish an API.) ## **Decision Drivers** - _Agent Framework_ shall provide sufficient abstraction to enable the construction of agents that could utilize potentially any LLM API. - _Agent Framework_ shall provide sufficient abstraction and building blocks for the most frequent types of agent collaboration. It should be easy to add new blocks as new collaboration methods emerge. - _Agent Framework_ shall provide building blocks to modify agent input and output to cover various customization scenarios. - _Agent Framework_ shall align with _SemanticKernel_ patterns: tools, DI, plugins, function-calling, etc. - _Agent Framework_ shall be extensible so that other libraries can build their own agents and chat experiences. - _Agent Framework_ shall be as simple as possible to facilitate extensibility. - _Agent Framework_ shall encapsulate complexity within implementation details, not calling patterns. - _Agent_ abstraction shall support different modalities (see [Agent Modalities](#agent-modalities) section). - An _Agent_ of any modality shall be able to interact with an _Agent_ of any other modality. - An _Agent_ shall be able to support its own modality requirements. (Specialization) - _Agent_ input and output shall align to SK content type `ChatMessageContent`. ## **Design - Analysis** Agents participate in a conversation, often in response to user or environmental input.

In addition to `Agent`, two fundamental concepts are identified from this pattern: - Conversation - Context for sequence of agent interactions. - Channel: ("Communication Path" from diagram) - The associated state and protocol with which the agent interacts with a single conversation. > Agents of different modalities must be free to satisfy the requirements presented by their modality. Formalizing the `Channel` concept provides a natural vehicle for this to occur. For an agent based on _chat-completion_, this means owning and managing a specific set of chat messages (chat-history) and communicating with a chat-completion API / endpoint. For an agent based on the _Open AI Assistant API_, this means defining a specific _thread_ and communicating with the Assistant API as a remote service. These concepts come together to suggest the following generalization:

Agent Pattern Diagram

After iterating with the team over these concepts, this generalization translates into the following high-level definitions:

Also shown are entities defined as part of the _ChatHistory_ optimization: `IChatHistoryHandler`, `ChatHistoryKernelAgent`, and `ChatHistoryChannel`. These _ChatHistory_ entities eliminates the requirement for _Agents_ that act on a locally managed `ChatHistory` instance (as opposed to agents managed via remotely hosted frameworks) to implement their own `AgentChannel`.

The `ChatCompletionAgent` implementation is able to integrate with any `IChatCompletionService` implementation. Since `IChatCompletionService` acts upon `ChatHistory`, this demonstrates how `ChatHistoryKernelAgent` may be simply implemented. Agent behavior is (naturally) constrained according to the specific behavior of any `IChatCompletionService`. For example, a connector that does not support function-calling will likewise not execute any `KernelFunction` as an _Agent_.

## **Design - Aggregator Agent** In order to support complex calling patterns, `AggregatorAgent` enables one or more agents participating in an `AgentChat` to present as a single logical `Agent`.

Agent Instantiation: ChatCompletion** Creating a `ChatCompletionAgent` aligns directly with how a `Kernel` object would be defined with an `IChatCompletionService` for outside of the _Agent Framework_, with the addition of provide agent specific instructions and identity. (_dotnet_) ```c# // Start with the Kernel IKernelBuilder builder = Kernel.CreateBuilder(); // Add any IChatCompletionService builder.AddOpenAIChatCompletion(...); // Include desired plugins / functions builder.Plugins.Add(...); // Include desired filters builder.Filters.Add(...); // Create the agent ChatCompletionAgent agent = new() { Instructions = "instructions", Name = "name", Kernel = builder.Build() }; ``` (_python_) ```python # Start with the Kernel kernel = Kernel() # Add any ChatCompletionClientBase kernel.add_service(AzureChatCompletion(service_id="agent", ...)) # Include desired plugins / functions kernel.add_plugin(...) # Include desired filters (via @kernel.filter decorator) # Create the agent agent = ChatCompletionAgent(service_id="agent", kernel=kernel, name="name", instructions="instructions") ``` **2. Agent Instantiation: OpenAI Assistant** Since every Assistant action is a call to a REST endpoint, `OpenAIAssistantAgent`, top-level operations are realized via static asynchronous factory methods: **Create:** (_dotnet_) ```c# // Start with the Kernel IKernelBuilder builder = Kernel.CreateBuilder(); // Include desired plugins / functions builder.Plugins.Add(...); // Create config and definition OpenAIServiceConfiguration config = new("apikey", "endpoint"); OpenAIAssistantDefinition definition = new() { Instructions = "instructions", Name = "name", Model = "gpt-4", }; // Create the agent OpenAIAssistantAgent agent = OpenAIAssistantAgent.CreateAsync( builder.Build(), config, definition); ``` (_python_) ```python # Start with the Kernel kernel = Kernel() # Include desired plugins / functions kernel.add_plugin(...) # Create config and definition config = OpenAIServiceConfiguration("apikey", "endpoint") definition = OpenAIAssistantDefinition(instructions="instructions", name="name", model="gpt-4") agent = OpenAIAssistantAgent.create(kernel=kernel, config=config, definition=definition) ``` **Retrieval:** (_dotnet_) ```c# // Start with the Kernel Kernel kernel = ...; // Create config OpenAIServiceConfiguration config = new("apikey", "endpoint"); // Create the agent based on an existing definition OpenAIAssistantAgent agent = OpenAIAssistantAgent.RetrieveAsync(kernel, config, "agent-id"); ``` (_python_) ```python # Start with the Kernel kernel = Kernel() # Create config config = OpenAIServiceConfiguration("apikey", "endpoint") # Create the agent based on an existing definition agent = OpenAIAssistantAgent.retrieve(kernel = kernel, config=config, agentid="agent-id") ``` **Inspection:** (_dotnet_) ```c# // Create config OpenAIServiceConfiguration config = new("apikey", "endpoint"); // Enumerate defined agents IAsyncEnumerable definitions = OpenAIAssistantAgent.ListDefinitionsAsync(config); ``` (_python_) ```python # Create config config = OpenAIServiceConfiguration("apikey", "endpoint") # Enumerate defined agents definitions = await OpenAIAssistantAgent.list_definitions(config=config) ``` **3. Agent Chat: Explicit** An _Agent_ may be explicitly targeted to respond in an `AgentGroupChat`. (_dotnet_) ```c# // Define agents ChatCompletionAgent agent1 = ...; OpenAIAssistantAgent agent2 = ...; // Create chat AgentGroupChat chat = new(); // Provide input for chat ChatMessageContent input = new (AuthorRole.User, "input"); await WriteMessageAsync(input); chat.AddChatMessage(input); // First invoke one agent, then the other, display each response. await WriteMessagesAsync(chat.InvokeAsync(agent1)); await WriteMessagesAsync(chat.InvokeAsync(agent2)); // The entire history may be accessed. // Agent specific history is an adaptaton of the primary history. await WriteMessagesAsync(chat.GetHistoryAsync()); await WriteMessagesAsync(chat.GetHistoryAsync(agent1)); await WriteMessagesAsync(chat.GetHistoryAsync(agent2)); ``` (_python_) ```python # Define agents agent1 = ChatCompletionAgent(...) agent2 = OpenAIAssistantAgent.create(...) # Create chat chat = AgentGroupChat() # Provide input for chat input = ChatMessageContent(AuthorRole.User, "input") await write_message(input) chat.add_chat_message(input) # First invoke one agent, then the other, display each response. await write_message(chat.invoke(agent1)) await write_message(chat.invoke(agent2)) # The entire history may be accessed. # Agent specific history is an adaptaton of the primary history. await write_message(chat.get_history()) await write_message(chat.get_history(agent1)) await write_message(chat.get_history(agent2)) ``` **4. Agent Chat: Multi-Turn** _Agents_ may also take multiple turns working towards an objective: (_dotnet_) ```c# // Define agents ChatCompletionAgent agent1 = ...; OpenAIAssistantAgent agent2 = ...; ChatCompletionAgent agent3 = ...; // Create chat with two agents. AgentGroupChat chat = new(agent1, agent2) { ExecutionSettings = { // Chat will continue until it meets the termination criteria. TerminationionStrategy = new MyTerminationStrategy(), } }; // Provide input for chat ChatMessageContent input = new(AuthorRole.User, "input"); await WriteMessageAsync(input); chat.AddChatMessage(input); // Agent may be added to an existing chat chat.AddAgent(agent3); // Execute the chat until termination await WriteMessagesAsync(chat.InvokeAsync()); ``` (_python_) ```python # Define agents agent1 = ChatCompletionAgent(...) agent2 = OpenAIAssistantAgent.create(...) agent3 = ChatCompletionAgent(...) // Create chat with two agents. chat = AgentGroupChat(agent1, agent2) { execution_settings = { # Chat will continue until it meets the termination criteria. terminationion_strategy = MyTerminationStrategy(), } } # Provide input for chat input = ChatMessageContent(AuthorRole.User, "input") await write_message(input) chat.add_chat_message(input) # Agent may be added to an existing chat chat.add_agent(agent3) # Execute the chat until termination await write_message(chat.invoke()) ``` ================================================ FILE: docs/decisions/0033-kernel-filters.md ================================================ --- # These are optional elements.

Example: ```csharp ILogger logger = loggerFactory.CreateLogger("MyLogger"); var kernel = Kernel.CreateBuilder() .AddOpenAIChatCompletion( modelId: TestConfiguration.OpenAI.ChatModelId, apiKey: TestConfiguration.OpenAI.ApiKey) .Build(); void MyInvokingHandler(object? sender, FunctionInvokingEventArgs e) { logger.LogInformation("Invoking: {FunctionName}", e.Function.Name) } void MyInvokedHandler(object? sender, FunctionInvokedEventArgs e) { if (e.Result.Metadata is not null && e.Result.Metadata.ContainsKey("Usage")) { logger.LogInformation("Token usage: {TokenUsage}", e.Result.Metadata?["Usage"]?.AsJson()); } } kernel.FunctionInvoking += MyInvokingHandler; kernel.FunctionInvoked += MyInvokedHandler; var result = await kernel.InvokePromptAsync("How many days until Christmas? Explain your thinking.") ``` There are a couple of problems with this approach: 1. Event handlers does not support dependency injection. It's hard to get access to specific service, which is registered in application, unless the handler is defined in the same scope where specific service is available. This approach provides some limitations in what place in solution the handler could be defined. (e.g. If developer wants to use `ILoggerFactory` in handler, the handler should be defined in place where `ILoggerFactory` instance is available). 2. It's not clear in what specific period of application runtime the handler should be attached to kernel. Also, it's not clear if developer needs to detach it at some point. 3. Mechanism of events and event handlers in .NET may not be familiar to .NET developers who didn't work with events previously. ## Decision Drivers 1. Dependency injection for handlers should be supported to easily access registered services within application. 2. There should not be any limitations where handlers are defined within solution, whether it's Startup.cs or separate file. 3. There should be clear way of registering and removing handlers at specific point of application runtime. 4. The mechanism of receiving and processing events in Kernel should be easy and common in .NET ecosystem. 5. New approach should support the same functionality that is available in Kernel Events - cancel function execution, change kernel arguments, change rendered prompt before sending it to AI etc. ## Decision Outcome Introduce Kernel Filters - the approach of receiving the events in Kernel in similar way as action filters in ASP.NET. Two new abstractions will be used across Semantic Kernel and developers will have to implement these abstractions in a way that will cover their needs. For function-related events: `IFunctionFilter` ```csharp public interface IFunctionFilter { void OnFunctionInvoking(FunctionInvokingContext context); void OnFunctionInvoked(FunctionInvokedContext context); } ``` For prompt-related events: `IPromptFilter` ```csharp public interface IPromptFilter { void OnPromptRendering(PromptRenderingContext context); void OnPromptRendered(PromptRenderedContext context); } ``` New approach will allow developers to define filters in separate classes and easily inject required services to process kernel event correctly: MyFunctionFilter.cs - filter with the same logic as event handler presented above: ```csharp public sealed class MyFunctionFilter : IFunctionFilter { private readonly ILogger _logger; public MyFunctionFilter(ILoggerFactory loggerFactory) { this._logger = loggerFactory.CreateLogger("MyLogger"); } public void OnFunctionInvoking(FunctionInvokingContext context) { this._logger.LogInformation("Invoking {FunctionName}", context.Function.Name); } public void OnFunctionInvoked(FunctionInvokedContext context) { var metadata = context.Result.Metadata; if (metadata is not null && metadata.ContainsKey("Usage")) { this._logger.LogInformation("Token usage: {TokenUsage}", metadata["Usage"]?.AsJson()); } } } ``` As soon as new filter is defined, it's easy to configure it to be used in Kernel using dependency injection (pre-construction) or add filter after Kernel initialization (post-construction): ```csharp IKernelBuilder kernelBuilder = Kernel.CreateBuilder(); kernelBuilder.AddOpenAIChatCompletion( modelId: TestConfiguration.OpenAI.ChatModelId, apiKey: TestConfiguration.OpenAI.ApiKey); // Adding filter with DI (pre-construction) kernelBuilder.Services.AddSingleton(); Kernel kernel = kernelBuilder.Build(); // Adding filter after Kernel initialization (post-construction) // kernel.FunctionFilters.Add(new MyAwesomeFilter()); var result = await kernel.InvokePromptAsync("How many days until Christmas? Explain your thinking."); ``` It's also possible to configure multiple filters which will be triggered in order of registration: ```csharp kernelBuilder.Services.AddSingleton(); kernelBuilder.Services.AddSingleton(); kernelBuilder.Services.AddSingleton(); ``` And it's possible to change the order of filter execution in runtime or remove specific filter if needed: ```csharp kernel.FunctionFilters.Insert(0, new InitialFilter()); kernel.FunctionFilters.RemoveAt(1); ``` ================================================ FILE: docs/decisions/0034-rag-in-sk.md ================================================ --- # These are optional elements.

Some of the approaches already exist in SK, and some of them could be added in the future for diverse development experience. The purpose of this ADR is to describe problematic places with memory-related functionality in SK, demonstrate how to achieve RAG in current version of SK and propose new design of public API for RAG. Considered options, that are presented in this ADR, do not contradict each other and can be supported all at the same time. The decision which option to support will be based on different factors including priority, actual requirement for specific functionality and general feedback. ### Vector DB integrations - Connectors There are 12 [vector DB connectors](https://github.com/microsoft/semantic-kernel/tree/main/dotnet/src/Connectors) (also known as `memory connectors`) implemented at the moment, and it may be unclear for developers how to use them. It's possible to call connector methods directly or use it via `TextMemoryPlugin` from [Plugins.Memory](https://www.nuget.org/packages/Microsoft.SemanticKernel.Plugins.Memory) NuGet package (prompt example: `{{recall 'company budget by year'}} What is my budget for 2024?`) Each connector has unique implementation, some of them rely on already existing .NET SDK from specific vector DB provider, and some of them have implemented functionality to use REST API of vector DB provider. Ideally, each connector should be always up-to-date and support new functionality. For some connectors maintenance cost is low, since there are no breaking changes included in new features or vector DB provides .NET SDK which is relatively easy to re-use. For other connectors maintenance cost is high, since some of them are still in `alpha` or `beta` development stage, breaking changes can be included or .NET SDK is not provided, which makes it harder to update. ### IMemoryStore interface Each memory connector implements `IMemoryStore` interface with methods like `CreateCollectionAsync`, `GetNearestMatchesAsync` etc., so it can be used as part of `TextMemoryPlugin`. By implementing the same interface, each integration is aligned, which makes it possible to use different vector DBs at runtime. At the same time it is disadvantage, because each vector DB can work differently, and it becomes harder to fit all integrations into already existing abstraction. For example, method `CreateCollectionAsync` from `IMemoryStore` is used when application tries to add new record to vector DB to the collection, which doesn't exist, so before insert operation, it creates new collection. In case of [Pinecone](https://www.pinecone.io/) vector DB, this scenario is not supported, because Pinecone index creation is an asynchronous process - API service will return 201 Created HTTP response with following property in response body (index is not ready for usage): ```json { // Other properties... "status": { "ready": false, "state": "Initializing" } } ``` In this case, it's impossible to insert a record to database immediately, so HTTP polling or similar mechanism should be implemented to cover this scenario. ### MemoryRecord as storage schema `IMemoryStore` interface uses `MemoryRecord` class as storage schema in vector DB. This means that `MemoryRecord` properties should be aligned to all possible connectors. As soon as developers will use this schema in their databases, any changes to schema may break the application, which is not a flexible approach. `MemoryRecord` contains property `ReadOnlyMemory Embedding` for embeddings and `MemoryRecordMetadata Metadata` for embeddings metadata. `MemoryRecordMetadata` contains properties like: - `string Id` - unique identifier. - `string Text` - data-related text. - `string Description` - optional title describing the content. - `string AdditionalMetadata` - field for saving custom metadata with a record. Since `MemoryRecord` and `MemoryRecordMetadata` are not sealed classes, it should be possible to extend them and add more properties as needed. Although, current approach still forces developers to have specific base schema in their vector DBs, which ideally should be avoided. Developers should have the ability to work with any schema of their choice, which will cover their business scenarios (similarly to Code First approach in Entity Framework). ### TextMemoryPlugin TextMemoryPlugin contains 4 Kernel functions: - `Retrieve` - returns concrete record from DB by key. - `Recall` - performs vector search and returns multiple records based on relevance. - `Save` - saves record in vector DB. - `Remove` - removes record from vector DB. All functions can be called directly from prompt. Moreover, as soon as these functions are registered in Kernel and Function Calling is enabled, LLM may decide to call specific function to achieve provided goal. `Retrieve` and `Recall` functions are useful to provide some context to LLM and ask a question based on data, but functions `Save` and `Remove` perform some manipulations with data in vector DB, which could be unpredicted or sometimes even dangerous (there should be no situations when LLM decides to remove some records, which shouldn't be deleted). ## Decision Drivers 1. All manipulations with data in Semantic Kernel should be safe. 2. There should be a clear way(s) how to use RAG pattern in Semantic Kernel. 3. Abstractions should not block developers from using vector DB of their choice with functionality, that cannot be achieved with provided interfaces or data types. ## Out of scope Some of the RAG-related frameworks contain functionality to support full cycle of RAG pattern: 1. **Read** data from specific resource (e.g. Wikipedia, OneDrive, local PDF file). 2. **Split** data in multiple chunks using specific logic. 3. **Generate** embeddings from data. 4. **Store** data to preferred vector DB. 5. **Search** data in preferred vector DB based on user query. 6. **Ask** LLM a question based on provided data. As for now, Semantic Kernel has following experimental features: - `TextChunker` class to **split** data in chunks. - `ITextEmbeddingGenerationService` abstraction and implementations to **generate** embeddings using OpenAI and HuggingFace models. - Memory connectors to **store** and **search** data. Since these features are experimental, they may be deprecated in the future if the decisions for RAG pattern won't require to provide and maintain listed abstractions, classes and connectors in Semantic Kernel. Tools for data **reading** is out of scope as for now. ## Considered Options ### Option 1 [Supported] - Prompt concatenation This option allows to manually construct a prompt with data, so LLM can respond to query based on provided context. It can be achieved by using manual string concatenation or by using prompt template and Kernel arguments. Developers are responsible for integration with vector DB of their choice, data search and prompt construction to send it to LLM. This approach doesn't include any memory connectors in Semantic Kernel out-of-the-box, but at the same time it gives an opportunity for developers to handle their data in the way that works for them the best. String concatenation: ```csharp var kernel = Kernel.CreateBuilder() .AddOpenAIChatCompletion("model-id", "api-key") .Build(); var builder = new StringBuilder(); // User is responsible for searching the data in a way of their choice, this is an example how it could look like. var data = await this._vectorDB.SearchAsync("Company budget by year"); builder.AppendLine(data); builder.AppendLine("What is my budget for 2024?"); var result = await kernel.InvokePromptAsync(builder.ToString()); ``` Prompt template and Kernel arguments: ```csharp var kernel = Kernel.CreateBuilder() .AddOpenAIChatCompletion("model-id", "api-key") .Build(); // User is responsible for searching the data in a way of their choice, this is an example how it could look like. var data = await this._vectorDB.SearchAsync("Company budget by year"); var arguments = new KernelArguments { ["budgetByYear"] = data }; var result = await kernel.InvokePromptAsync("{{budgetByYear}} What is my budget for 2024?", arguments); ``` ### Option 2 [Supported] - Memory as Plugin This approach is similar to Option 1, but data search step is part of prompt rendering process. Following list contains possible plugins to use for data search: - [ChatGPT Retrieval Plugin](https://github.com/openai/chatgpt-retrieval-plugin) - this plugin should be hosted as a separate service. It has integration with various [vector databases](https://github.com/openai/chatgpt-retrieval-plugin?tab=readme-ov-file#choosing-a-vector-database). - [SemanticKernel.Plugins.Memory.TextMemoryPlugin](https://www.nuget.org/packages/Microsoft.SemanticKernel.Plugins.Memory) - Semantic Kernel solution, which supports various vector databases. - Custom user plugin. ChatGPT Retrieval Plugin: ```csharp var kernel = Kernel.CreateBuilder() .AddOpenAIChatCompletion("model-id", "api-key") .Build(); // Import ChatGPT Retrieval Plugin using OpenAPI specification // https://github.com/openai/chatgpt-retrieval-plugin/blob/main/.well-known/openapi.yaml await kernel.ImportPluginFromOpenApiAsync("ChatGPTRetrievalPlugin", openApi!, executionParameters: new(authCallback: async (request, cancellationToken) => { request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", "chat-gpt-retrieval-plugin-token"); })); const string Query = "What is my budget for 2024?"; const string Prompt = "{{ChatGPTRetrievalPlugin.query_query_post queries=$queries}} {{$query}}"; var arguments = new KernelArguments { ["query"] = Query, ["queries"] = JsonSerializer.Serialize(new List { new { query = Query, top_k = 1 } }), }; var result = await kernel.InvokePromptAsync(Prompt, arguments); ``` TextMemoryPlugin: ```csharp var kernel = Kernel.CreateBuilder() .AddOpenAIChatCompletion("model-id", "api-key") .Build(); // NOTE: If the decision will be to continue support memory-related public API, then it should be revisited. // It should be up-to-date with new Semantic Kernel patterns. // Example: instead of `WithChromaMemoryStore`, it should be `AddChromaMemoryStore`. var memory = new MemoryBuilder() .WithChromaMemoryStore("https://chroma-endpoint") .WithOpenAITextEmbeddingGeneration("text-embedding-ada-002", "api-key") .Build(); kernel.ImportPluginFromObject(new TextMemoryPlugin(memory)); var result = await kernel.InvokePromptAsync("{{recall 'Company budget by year'}} What is my budget for 2024?"); ``` Custom user plugin: ```csharp public class MyDataPlugin { [KernelFunction("search")] public async Task SearchAsync(string query) { // Make a call to vector DB and return results. // Here developer can use already existing .NET SDK from specific vector DB provider. // It's also possible to re-use Semantic Kernel memory connector directly here: // new ChromaMemoryStore(...).GetNearestMatchAsync(...) } } var kernel = Kernel.CreateBuilder() .AddOpenAIChatCompletion("model-id", "api-key") .Build(); kernel.ImportPluginFromType(); var result = await kernel.InvokePromptAsync("{{search 'Company budget by year'}} What is my budget for 2024?"); ``` The reason why custom user plugin is more flexible than `TextMemoryPlugin` is because `TextMemoryPlugin` requires all vector DBs to implement `IMemoryStore` interface with disadvantages described above, while custom user plugin can be implemented in a way of developer's choice. There won't be any restrictions on DB record schema or requirement to implement specific interface. ### Option 3 [Partially supported] - Prompt concatenation using Prompt Filter This option is similar to Option 1, but prompt concatenation will happen on Prompt Filter level: Prompt filter: ```csharp public sealed class MyPromptFilter : IPromptFilter { public void OnPromptRendering(PromptRenderingContext context) { // Handling of prompt rendering event... } public void OnPromptRendered(PromptRenderedContext context) { var data = "some data"; var builder = new StringBuilder(); builder.AppendLine(data); builder.AppendLine(context.RenderedPrompt); // Override rendered prompt before sending it to AI and include data context.RenderedPrompt = builder.ToString(); } } ``` Usage: ```csharp var kernel = Kernel.CreateBuilder() .AddOpenAIChatCompletion("model-id", "api-key") .Build(); kernel.PromptFilters.Add(new MyPromptFilter()); var result = await kernel.InvokePromptAsync("What is my budget for 2024?"); ``` From the usage perspective, prompt will contain just user query without additional data. The data will be added to the prompt behind the scenes. The reason why this approach is **partially supported** is because a call to vector DB most probably will be an asynchronous, but current Kernel filters don't support asynchronous scenarios. So, in order to support asynchronous calls, new type of filters should be added to Kernel: `IAsyncFunctionFilter` and `IAsyncPromptFilter`. They will be the same as current `IFunctionFilter` and `IPromptFilter` but with async methods. ### Option 4 [Proposal] - Memory as part of PromptExecutionSettings This proposal is another possible way how to implement RAG pattern in SK, on top of already existing approaches described above. Similarly to `TextMemoryPlugin`, this approach will require abstraction layer and each vector DB integration will be required to implement specific interface (it could be existing `IMemoryStore` or completely new one) to be compatible with SK. As described in _Context and Problem Statement_ section, the abstraction layer has its advantages and disadvantages. User code will look like this: ```csharp var kernel = Kernel.CreateBuilder() .AddOpenAIChatCompletion("model-id", "api-key") .Build(); var executionSettings = new OpenAIPromptExecutionSettings { Temperature = 0.8, MemoryConfig = new() { // This service could be also registered using DI with specific lifetime Memory = new ChromaMemoryStore("https://chroma-endpoint"), MinRelevanceScore = 0.8, Limit = 3 } }; var function = KernelFunctionFactory.CreateFromPrompt("What is my budget for 2024?", executionSettings); var result = await kernel.InvokePromptAsync("What is my budget for 2024?"); ``` Data search and prompt concatenation will happen behind the scenes in `KernelFunctionFromPrompt` class. ## Decision Outcome Temporary decision is to provide more examples how to use memory in Semantic Kernel as Plugin. The final decision will be ready based on next memory-related requirements. ================================================ FILE: docs/decisions/0035-skfunction-type-descriptions.md ================================================ --- # These are optional elements. Feel free to remove any of them. status: accepted date: 2023-11-8 contact: alliscode deciders: markwallace, mabolan consulted: SergeyMenshykh informed: --- # Providing more type information to SKFunctions and Planners ## Context and Problem Statement Today, Semantic Kernel only retains a small amount of information about the parameters of SKFunctions, and no information at all about the output of an SKFunction. This has a large negative impact on the effectiveness of our planners because it is not possible to adequately describe the schema of the the plugin function's inputs and outputs. Planners depend on a description of the plugins available to it, which we refer to as a Functions Manual. Think of this as the user manual that is provided to the LLM and is intended to explain to the LLM the functions that are available to it and how they can be used. An example of a current Functions Manual from our Sequential planner looks like this: ``` DatePluginSimpleComplex.GetDate1: description: Gets the date with the current date offset by the specified number of days. inputs: - numDays: The number of days to offset the date by from today. Positive for future, negative for past. WeatherPluginSimpleComplex.GetWeatherForecast1: description: Gets the weather forecast for the specified date and the current location, and time. inputs: - date: The date for the forecast ``` This Functions Manual describes two plugin functions that are available to the LLM, one to get the current date with an offset in days, and one to get the weather forecast for a given date. A simple question that our customer might want our planners to be able to answer with these plugin functions would be "What is the weather forecast for tomorrow?". Creating and executing a plan to answer this question would require invoking the first function, and then passing the result of that as a parameter to the invocation of the second function. If written in pseudo code, the plan would look something like this: ```csharp var dateResponse = DatePluginSimpleComplex.GetDate1(1); var forecastResponse = WeatherPluginSimpleComplex.GetWeatherForecast1(dateResponse); return forecastResponse; ``` This seems like a reasonable plan, and this is indeed comparable to what out Sequential planner would come up with. This might also work, as long as the unknown return type of the first function happens to match the unknown parameter type of the second function. The Functions Manual that we are providing to the LLM however, does not specify the necessary information to know if these types will match up. One way that we could provide the missing type information is to use Json Schema. This also happens to be the same way that OpenAPI specs provide type information for inputs and outputs, and this provides a cohesive solution for local and remote plugins. If we utilize Json Schema, then our Functions Manual can look more like this: ```json [ { "name": "DatePluginSimpleComplex.GetDate1", "description": "Gets the date with the current date offset by the specified number of days.", "parameters": { "type": "object", "required": ["numDays"], "properties": { "numDays": { "type": "integer", "description": "The number of days to offset the date by from today. Positive for future, negative for past." } } }, "responses": { "200": { "description": "Successful response.", "content": { "application/json": { "schema": { "type": "object", "properties": { "date": { "type": "string" } }, "description": "The date." } } } } } }, { "name": "WeatherPluginSimpleComplex.GetWeatherForecast1", "description": "Gets the weather forecast for the specified date and the current location, and time.", "parameters": { "type": "object", "required": ["date"], "properties": { "date": { "type": "string", "description": "The date for the forecast" } } }, "responses": { "200": { "description": "Successful response.", "content": { "application/json": { "schema": { "type": "object", "properties": { "degreesFahrenheit": { "type": "integer" } }, "description": "The forecasted temperature in Fahrenheit." } } } } } } ] ``` This Functions Manual provides much more information about the the inputs and outputs of the functions that the LLM has access to. It allows to see that the output of the first functions is a complex objects that contain the information required by the second function. This also comes with an increase in the amount of tokens used, however the increase in functionality derived the type information outweighs this expense. With this information we can now expect the LLM to generate a plan that includes an understanding of how values should be extracted from outputs and passed to inputs. One effective method that we've used in testing is to ask the LLM to specify inputs as a Json Path into the appropriate output. An equivalent plan shown in pseudo code would look like this: ```csharp var dateResponse = DatePluginSimpleComplex.GetDate1(1); var forecastResponse = WeatherPluginSimpleComplex.GetWeatherForecast1(dateResponse.date); return forecastResponse.degreesFahrenheit; ``` ## Proposal In order to be able to generate complete Function Manuals such as the Json Schema based examples above, SKFunctions and their associated Function Views will need to maintain more information about their parameter types and return types. Function Views currently have the following definition: ```csharp public sealed record FunctionView( string Name, string PluginName, string Description = "", IReadOnlyList? Parameters = null) { /// /// List of function parameters /// public IReadOnlyList Parameters { get; init; } = Parameters ?? Array.Empty(); } ``` The function parameters are described by the collection of `ParameterView` objects which contain a semantic description, and provide a place to add more type information. There is however no existing place to put the type information and semantic description of the function output. To fix this we will add a new property called `ReturnParameterView` to the `FunctionView`: ```csharp public sealed record FunctionView( string Name, string PluginName, string Description = "", IReadOnlyList? Parameters = null, ReturnParameterView? ReturnParameter = null) { /// /// List of function parameters /// public IReadOnlyList Parameters { get; init; } = Parameters ?? Array.Empty(); /// /// Function output /// public ReturnParameterView ReturnParameter { get; init; } = ReturnParameter ?? new ReturnParameterView(); } ``` `ParameterView` objects currently contain a `ParameterViewType` property which contains some information about the type of the parameter but is limited to JSON types ([string, number, boolean, null, object, array]) and has no way of describing the structure of an object. To add the extra type information that is needed, we can add a native `System.Type` property. This would work well for local functions as the parameter Type would always be accessible when importing the SKFunction. It will also be required for hydrating native types from LLM responses. For remote plugins however, the native type for objects will not be known and may not even exist so the `System.Type` doesn't help. For this case we need to extract the type information from the OpenAPI specification and store it in a property that allows for previously unknown schemas. Options for this property type include `JsonSchema` from an OSS library such as JsonSchema.Net or NJsonSchema, `JsonDocument` from System.Text.Json, or a `string` containing the Json serialized schema. | Type | Pros | Cons | | ------------------------- | ------------------------------------------------------------ | ---------------------------------------------------------- | | JsonSchema.Net.JsonSchema | Popular and has frequent updates, built on top of System.Net | Takes a dependency on OSS in SK core | | NJsonShema.JsonSchema | Very popular, frequent updates, long term project | Built on top of Json.Net (Newtonsoft) | | JsonDocument | Native C# type, fast and flexible | Not a Json Schema, but a Json DOM container for the schema | | String | Native C# type | Not a Json Schema or Json DOM, very poor type hinting | To avoid taking a dependency on 3rd party libraries in the core abstractions project, we will use a `JsonDocument` type to hold the Json Schemas that are created when loading remote plugins. The libraries needed to create or extract these schemas can be included in the packages that require them, namely Functions.OpenAPI, Planners.Core, and Connectors.AI.OpenAI. The `NativeType` property will be populated when loading native functions and will be used to generate a Json Schema when needed, as well as for hydrating native types from LLM responses in planners and semantic functions. ```csharp public sealed record ParameterView( string Name, string? Description = null, string? DefaultValue = null, ParameterViewType? Type = null, bool? IsRequired = null, Type? NativeType = null, JsonDocument? Schema = null); ``` ================================================ FILE: docs/decisions/0036-semantic-kernel-release-versioning.md ================================================ --- status: accepted contact: markwallace date: 2024-023-2706 deciders: sergeymenshykh, markwallace, rbarreto, dmytrostruk consulted: matthewbolanos informed: matthewbolanos --- # Semantic Kernel Release Versioning ## Context and Problem Statement This ADR summarizes the approach used to change the package version numbers when releasing a new version of the Semantic Kernel. The ADR is relevant to the .Net, Java and Python releases of the Semantic Kernel (once the packages reach v1.0). 1. [Semantic Kernel on NuGet](https://www.nuget.org/packages/Microsoft.SemanticKernel/) 1. [Semantic Kernel on Python Package Index](https://pypi.org/project/semantic-kernel/) 1. [Semantic Kernel on Maven Central](https://central.sonatype.com/search?q=com.microsoft.semantic-kernel) ## Decision Drivers ### Semantic Versioning & Documentation - We will not adhere to strict [semantic versioning](https://semver.org/) because this is not strictly followed by NuGet packages. - We will document trivial incompatible API changes in the release notes - We expect most regular updates to the Semantic Kernel will include new features and will be backward compatible ### Packages Versioning - We will use the same version number on all packages when we create a new release - All packages are included in every release and version numbers are incremented even if a specific package has not been changed - We will test each release to ensure all packages are compatible - We recommend customers use the same version of packages and this is the configuration we will support ### Major Version - We will not increment the MAJOR version for low impact incompatible API changes 1 - We will not increment the MAJOR version for API changes to experimental features or alpha packages 1 Low impact incompatible API changes typically only impact the Semantic Kernel internal implementation or unit tests. We are not expecting to make any significant changes to the API surface of the Semantic Kernel. ### Minor Version - We will increment the MINOR version when we add functionality in a backward compatible manner ### Patch Version - We will increment the PATCH version when by the time of release we only made backward compatible bug fixes. ### Version Suffixes The following version suffixes are used: - `preview` or `beta` - This suffix is used for packages which are close to release e.g. version `1.x.x-preview` will be used for a package which is close to it's version 1.x release. Packages will be feature complete and interfaces will be very close to the release version. The `preview` suffix is used with .Net releases and `beta` is used with Python releases. - `alpha` - This suffix is used for packages which are not feature complete and where the public interfaces are still under development and are expected to change. ================================================ FILE: docs/decisions/0037-audio-naming.md ================================================ --- # These are optional elements. Feel free to remove any of them. status: proposed contact: dmytrostruk date: 2023-02-22 deciders: sergeymenshykh, markwallace, rbarreto, dmytrostruk --- # Audio Abstraction and Implementation naming ## Context and Problem Statement ### Abstraction Today we have following interfaces to work with audio: - IAudioToTextService - ITextToAudioService `IAudioToTextService` accepts audio as input and returns text as output and `ITextToAudioService` accepts text as input and returns audio as output. The naming of these abstractions does not indicate the nature of audio conversion. For example, `IAudioToTextService` interface does not indicate whether it's audio transcription or audio translation. This may be a problem and at the same time an advantage. By having general text-to-audio and audio-to-text interfaces, it is possible to cover different types of audio conversion (transcription, translation, speech recognition, music recognition etc) using the same interface, because at the end it's just text-in/audio-out contract and vice versa. In this case, we can avoid creating multiple audio interfaces, which possibly may contain exactly the same method signature. On the other hand, it may be a problem in case when there is a need to differentiate between specific abstractions of audio conversion inside user application or Kernel itself in the future. ### Implementation Another problem is with audio implementation naming for OpenAI: - AzureOpenAIAudioToTextService - OpenAIAudioToTextService - AzureOpenAITextToAudioService - OpenAITextToAudioService In this case, the naming is incorrect, because it does not use official naming from OpenAI docs, which may be confusing. For example, audio-to-text conversion is called [Speech to text](https://platform.openai.com/docs/guides/speech-to-text). However, renaming `OpenAIAudioToTextService` to `OpenAISpeechToTextService` might not be enough, because speech to text API has 2 different endpoints - `transcriptions` and `translations`. Current OpenAI audio connector uses `transcriptions` endpoint, but the name `OpenAISpeechToTextService` won't reflect that. A possible name could be `OpenAIAudioTranscriptionService`. ## Considered Options ### [Abstraction - Option #1] Keep the naming as it is for now (`IAudioToTextService`, `ITextToAudioService`) and use these interfaces for all audio-related connectors, until we see that some specific audio conversion won't fit into existing interface signature. The main question for this option would be - could there be any possibility that it will be required to differentiate between audio conversion types (transcription, translation etc.) in business logic and/or Kernel itself? Probably yes, when the application wants to use both `transcription` and `translation` in the logic. It won't be clear which audio interface should be injected to perform concrete conversion. In this case, it's still possible to keep current interface names, but create child interfaces to specify concrete audio conversion type, for example: ```csharp public interface IAudioTranscriptionService : IAudioToTextService {} public interface IAudioTranslationService : IAudioToTextService {} ``` The disadvantage of it is that most probably these interfaces will be empty. The main purpose would be the ability to differentiate when using both of them. ### [Abstraction - Option #2] Rename `IAudioToTextService` and `ITextToAudioService` to more concrete type of conversion (e.g. `ITextToSpeechService`) and for any other type of audio conversion - create a separate interface, which potentially could be exactly the same except naming. The disadvantage of this approach is that even for the same type of conversion (e.g speech-to-text), it will be hard to pick a good name, because in different AI providers this capability is named differently, so it will be hard to avoid inconsistency. For example, in OpenAI it's [Audio transcription](https://platform.openai.com/docs/api-reference/audio/createTranscription) while in Hugging Face it's [Automatic Speech Recognition](https://huggingface.co/models?pipeline_tag=automatic-speech-recognition). The advantage of current name (`IAudioToTextService`) is that it's more generic and cover both Hugging Face and OpenAI services. It's named not after AI capability, but rather interface contract (audio-in/text-out). ### [Implementation] As for implementations, there are two options as well - keep it as it is or rename classes based on how the capability is called by AI provider and most probably renaming is the best choice here, because from the user point of view, it will be easier to understand which concrete OpenAI capability is used (e.g. `transcription` or `translation`), so it will be easier to find related documentation about it and so on. Proposed renaming: - AzureOpenAIAudioToTextService -> AzureOpenAIAudioTranscriptionService - OpenAIAudioToTextService -> OpenAIAudioTranscriptionService - AzureOpenAITextToAudioService -> AzureOpenAITextToSpeechService - OpenAITextToAudioService -> OpenAITextToSpeechService ## Naming comparison | AI Provider | Audio conversion | Proposed Interface | Proposed Implementation | | ------------ | ------------------- | -------------------------- | ----------------------------------- | | Microsoft | Speech-to-text | IAudioTranscriptionService | MicrosoftSpeechToTextService | | Hugging Face | Speech recognition | IAudioTranscriptionService | HuggingFaceSpeechRecognitionService | | AssemblyAI | Transcription | IAudioTranscriptionService | AssemblyAIAudioTranscriptionService | | OpenAI | Audio transcription | IAudioTranscriptionService | OpenAIAudioTranscriptionService | | Google | Speech-to-text | IAudioTranscriptionService | GoogleSpeechToTextService | | Amazon | Transcription | IAudioTranscriptionService | AmazonAudioTranscriptionService | | Microsoft | Speech translation | IAudioTranslationService | MicrosoftSpeechTranslationService | | OpenAI | Audio translation | IAudioTranslationService | OpenAIAudioTranslationService | | Meta | Text-to-music | ITextToMusicService | MetaTextToMusicService | | Microsoft | Text-to-speech | ITextToSpeechService | MicrosoftTextToSpeechService | | OpenAI | Text-to-speech | ITextToSpeechService | OpenAITextToSpeechService | | Google | Text-to-speech | ITextToSpeechService | GoogleTextToSpeechService | | Amazon | Text-to-speech | ITextToSpeechService | AmazonTextToSpeechService | | Hugging Face | Text-to-speech | ITextToSpeechService | HuggingFaceTextToSpeechService | | Meta | Text-to-sound | TBD | TBD | | Hugging Face | Text-to-audio | TBD | TBD | | Hugging Face | Audio-to-audio | TBD | TBD | ## Decision Outcome Rename already existing audio connectors to follow provided naming in `Naming comparison` table and use the same naming for future audio abstractions and implementations. ================================================ FILE: docs/decisions/0038-completion-service-selection.md ================================================ --- # These are optional elements.

The `IAIServiceSelector` implementation will return either a chat completion service, text generation service or it could return a service that implements both. The prompt will be run using chat completion by default and falls back to text generation as the alternate option. The behavior supersedes that description in [ADR-0015](0015-completion-service-selection.md) ## Decision Drivers - Chat completion services are becoming dominant in the industry e.g. OpenAI has deprecated most of it's text generation services. - Chat completion generally provides better responses and the ability to use advanced features e.g. tool calling. ## Decision Outcome Chosen option: Keep the current behavior as described above. ================================================ FILE: docs/decisions/0039-set-plugin-name-in-metadata.md ================================================ --- # These are optional elements.

The reason for this behavior is to allow a `KernelFunction` instance to be associated with multiple `KernelPlugin` instances. The downside of this behavior is the `KernelFunctionMetadata.PluginName` property is not available to `IFunctionFilter` callbacks. The purpose of this ADR is to propose a change that will allow developers to decide when `KernelFunctionMetadata.PluginName` will be populated. Issues: 1. [Investigate if we should fix the PluginName in the KernelFunction metadata](https://github.com/microsoft/semantic-kernel/issues/4706) 1. [Plugin name inside FunctionInvokingContext in th IFunctionFilter is null](https://github.com/microsoft/semantic-kernel/issues/5452) ## Decision Drivers - Do not break existing applications. - Provide ability to make the `KernelFunctionMetadata.PluginName` property available to `IFunctionFilter` callbacks. ## Considered Options - Clone each `KernelFunction` when it is added to a `KernelPlugin` and set the plugin name in the clone `KernelFunctionMetadata`. - Add a new parameter to `KernelPluginFactory.CreateFromFunctions` to enable setting the plugin name in the associated `KernelFunctionMetadata` instances. Once set the `KernelFunctionMetadata.PluginName` cannot be changed. Attempting to do so will result in an `InvalidOperationException` being thrown. - Leave as is and do not support this use case as it may make the behavior of the Semantic Kernel seem inconsistent. ## Decision Outcome Chosen option: Clone each `KernelFunction`, because result is a consistent behavior and allows the same function can be added to multiple `KernelPlugin`'s. ## Pros and Cons of the Options ### Clone each `KernelFunction` PR: https://github.com/microsoft/semantic-kernel/pull/5422 - Bad, the same function can be added to multiple `KernelPlugin`'s. - Bad, because behavior is consistent. - Good, because there are not breaking change to API signature. - Bad, because additional `KernelFunction` instances are created. ### Add a new parameter to `KernelPluginFactory.CreateFromFunctions` PR: https://github.com/microsoft/semantic-kernel/pull/5171 - Good, because no additional `KernelFunction` instances are created. - Bad, because the same function cannot be added to multiple `KernelPlugin`'s - Bad, because it will be confusing i.e. depending on how the `KernelPlugin` is created it will behave differently. - Bad, because there is a minor breaking change to API signature. ================================================ FILE: docs/decisions/0040-chat-prompt-xml-support.md ================================================ --- # These are optional elements.

Developers can create prompts which include `` tags and these will be parsed (using an XML parser) and converted into instances of `ChatMessageContent`. See [mapping of prompt syntax to completion service model](./0020-prompt-syntax-mapping-to-completion-service-model.md) for more information. Currently it is possible to use variables and function calls to insert `` tags into a prompt as shown here: ```csharp string system_message = "This is the system message"; var template = """ {{$system_message}} First user message """; var promptTemplate = kernelPromptTemplateFactory.Create(new PromptTemplateConfig(template)); var prompt = await promptTemplate.RenderAsync(kernel, new() { ["system_message"] = system_message }); var expected = """ This is the system message First user message """; ``` This is problematic if the input variable contains user or indirect input and that content contains XML elements. Indirect input could come from an email. It is possible for user or indirect input to cause an additional system message to be inserted e.g. ```csharp string unsafe_input = "This is the newer system message"; var template = """ This is the system message {{$user_input}} """; var promptTemplate = kernelPromptTemplateFactory.Create(new PromptTemplateConfig(template)); var prompt = await promptTemplate.RenderAsync(kernel, new() { ["user_input"] = unsafe_input }); var expected = """ This is the system message This is the newer system message """; ``` Another problematic pattern is as follows: ```csharp string unsafe_input = ""; var template = """ This is the system message {{$user_input}} """; var promptTemplate = kernelPromptTemplateFactory.Create(new PromptTemplateConfig(template)); var prompt = await promptTemplate.RenderAsync(kernel, new() { ["user_input"] = unsafe_input }); var expected = """ This is the system message """; ``` This ADR details the options for developers to control message tag injection. ## Decision Drivers - By default input variables and function return values should be treated as being unsafe and must be encoded. - Developers must be able to "opt in" if they trust the content in input variables and function return values. - Developers must be able to "opt in" for specific input variables. - Developers must be able to integrate with tools that defend against prompt injection attacks e.g. [Prompt Shields](https://learn.microsoft.com/en-us/azure/ai-services/content-safety/concepts/jailbreak-detection). ***Note: For the remainder of this ADR input variables and function return values are referred to as "inserted content".*** ## Considered Options - HTML encode all inserted content by default. ## Decision Outcome Chosen option: "HTML encode all inserted content by default.", because it meets k.o. criterion decision driver and is a well understood pattern. ## Pros and Cons of the Options ### HTML Encode Inserted Content by Default This solution work as follows: 1. By default inserted content is treated as unsafe and will be encoded. 1. By default `HttpUtility.HtmlEncode` in dotnet and `html.escape` in Python are used to encode all inserted content. 1. When the prompt is parsed into Chat History the text content will be automatically decoded. 1. By default `HttpUtility.HtmlDecode` in dotnet and `html.unescape` in Python are used to decode all Chat History content. 1. Developers can opt out as follows: 1. Set `AllowUnsafeContent = true` for the `PromptTemplateConfig` to allow function call return values to be trusted. 1. Set `AllowUnsafeContent = true` for the `InputVariable` to allow a specific input variable to be trusted. 1. Set `AllowUnsafeContent = true` for the `KernelPromptTemplateFactory` or `HandlebarsPromptTemplateFactory` to trust all inserted content i.e. revert to behavior before these changes were implemented. In Python, this is done on each of the `PromptTemplate` classes, through the `PromptTemplateBase` class. - Good, because values inserted into a prompt are not trusted by default. - Bad, because there isn't a reliable way to decode message tags that were encoded. - Bad, because existing applications that have prompts with input variables or function calls which returns `` tags will have to be updated. ## Examples #### Plain Text ```csharp string chatPrompt = @" What is Seattle?

At the time of writing the ARD, two new connectors are being added that support function calling, each with its own specific model for function calling. The design, in which each new connector introduces its own specific model class for function calling, does not scale well from the connector development perspective and does not allow for polymorphic use of connectors by SK consumer code. Another scenario in which it would be beneficial to have an LLM/service-agnostic function calling model classes is to enable agents to pass function calls to one another. In this situation, an agent using the OpenAI Assistant API connector/LLM may pass the function call content/request/model for execution to another agent that build on top of the OpenAI chat completion API. This ADR describes the high-level details of the service-agnostic function-calling model classes, while leaving the low-level details to the implementation phase. Additionally, this ADR outlines the identified options for various aspects of the design. Requirements - https://github.com/microsoft/semantic-kernel/issues/5153 ## Decision Drivers 1. Connectors should communicate LLM function calls to the connector callers using service-agnostic function model classes. 2. Consumers should be able to communicate function results back to connectors using service-agnostic function model classes. 3. All existing function calling behavior should still work. 4. It should be possible to use service-agnostic function model classes without relying on the OpenAI package or any other LLM-specific one. 5. It should be possible to serialize a chat history object with function call and result classes so it can be rehydrated in the future (and potentially run the chat history with a different AI model). 6. It should be possible to pass function calls between agents. In multi-agent scenarios, one agent can create a function call for another agent to complete it. 7. It should be possible to simulate a function call. A developer should be able to add a chat message with a function call they created to a chat history object and then run it with any LLM (this may require simulating function call IDs in the case of OpenAI). ## 1. Service-agnostic function call model classes Today, SK relies on connector specific content classes to communicate LLM intent to call function(s) to the SK connector caller: ```csharp IChatCompletionService chatCompletionService = kernel.GetRequiredService(); ChatHistory chatHistory = new ChatHistory(); chatHistory.AddUserMessage("Given the current time of day and weather, what is the likely color of the sky in Boston?"); // The OpenAIChatMessageContent class is specific to OpenAI connectors - OpenAIChatCompletionService, AzureOpenAIChatCompletionService. OpenAIChatMessageContent result = (OpenAIChatMessageContent)await chatCompletionService.GetChatMessageContentAsync(chatHistory, settings, kernel); // The ChatCompletionsFunctionToolCall belongs Azure.AI.OpenAI package that is OpenAI specific. List toolCalls = result.ToolCalls.OfType().ToList(); chatHistory.Add(result); foreach (ChatCompletionsFunctionToolCall toolCall in toolCalls) { string content = kernel.Plugins.TryGetFunctionAndArguments(toolCall, out KernelFunction? function, out KernelArguments? arguments) ? JsonSerializer.Serialize((await function.InvokeAsync(kernel, arguments)).GetValue()) : "Unable to find function. Please try again!"; chatHistory.Add(new ChatMessageContent( AuthorRole.Tool, content, metadata: new Dictionary(1) { { OpenAIChatMessageContent.ToolIdProperty, toolCall.Id } })); } ``` Both `OpenAIChatMessageContent` and `ChatCompletionsFunctionToolCall` classes are OpenAI-specific and cannot be used by non-OpenAI connectors. Moreover, using the LLM vendor-specific classes complicates the connector's caller code and makes it impossible to work with connectors polymorphically - referencing a connector through the `IChatCompletionService` interface while being able to swap its implementations. To address this issues, we need a mechanism that allows communication of LLM intent to call functions to the caller and returning function call results back to LLM in a service-agnostic manner. Additionally, this mechanism should be extensible enough to support potential multi-modal cases when LLM requests function calls and returns other content types in a single response. Considering that the SK chat completion model classes already support multi-modal scenarios through the `ChatMessageContent.Items` collection, this collection can also be leveraged for function calling scenarios. Connectors would need to map LLM function calls to service-agnostic function content model classes and add them to the items collection. Meanwhile, connector callers would execute the functions and communicate the execution results back through the items collection as well. A few options for the service-agnostic function content model classes are being considered below. ### Option 1.1 - FunctionCallContent to represent both function call (request) and function result This option assumes having one service-agnostic model class - `FunctionCallContent` to communicate both function call and function result: ```csharp class FunctionCallContent : KernelContent { public string? Id {get; private set;} public string? PluginName {get; private set;} public string FunctionName {get; private set;} public KernelArguments? Arguments {get; private set; } public object?/FunctionResult/string? Result {get; private set;} // The type of the property is being described below. public string GetFullyQualifiedName(string functionNameSeparator = "-") {...} public Task InvokeAsync(Kernel kernel, CancellationToken cancellationToken = default) { // 1. Search for the plugin/function in kernel.Plugins collection. // 2. Create KernelArguments by deserializing Arguments. // 3. Invoke the function. } } ``` **Pros**: - One model class to represent both function call and function result. **Cons**: - Connectors will need to determine whether the content represents a function call or a function result by analyzing the role of the parent `ChatMessageContent` in the chat history, as the type itself does not convey its purpose. * This may not be a con at all because a protocol defining a specific role (AuthorRole.Tool?) for chat messages to pass function results to connectors will be required. Details are discussed below in this ADR. ### Option 1.2 - FunctionCallContent to represent a function call and FunctionResultContent to represent the function result This option proposes having two model classes - `FunctionCallContent` for communicating function calls to connector callers: ```csharp class FunctionCallContent : KernelContent { public string? Id {get;} public string? PluginName {get;} public string FunctionName {get;} public KernelArguments? Arguments {get;} public Exception? Exception {get; init;} public Task InvokeAsync(Kernel kernel,CancellationToken cancellationToken = default) { // 1. Search for the plugin/function in kernel.Plugins collection. // 2. Create KernelArguments by deserializing Arguments. // 3. Invoke the function. } public static IEnumerable GetFunctionCalls(ChatMessageContent messageContent) { // Returns list of function calls provided via collection. } } ``` and - `FunctionResultContent` for communicating function results back to connectors: ```csharp class FunctionResultContent : KernelContent { public string? Id {get; private set;} public string? PluginName {get; private set;} public string? FunctionName {get; private set;} public object?/FunctionResult/string? Result {get; set;} public ChatMessageContent ToChatMessage() { // Creates and adds the current instance of the class to the collection. } } ``` **Pros**: - The explicit model, compared to the previous option, allows the caller to clearly declare the intent of the content, regardless of the role of the parent `ChatMessageContent` message. * Similar to the drawback for the option above, this may not be an advantage because the protocol defining the role of chat message to pass the function result to the connector will be required. **Cons**: - One extra content class. ### The connector caller code example: ```csharp //The GetChatMessageContentAsync method returns only one choice. However, there is a GetChatMessageContentsAsync method that can return multiple choices. ChatMessageContent messageContent = await completionService.GetChatMessageContentAsync(chatHistory, settings, kernel); chatHistory.Add(messageContent); // Adding original chat message content containing function call(s) to the chat history IEnumerable functionCalls = FunctionCallContent.GetFunctionCalls(messageContent); // Getting list of function calls. // Alternatively: IEnumerable functionCalls = messageContent.Items.OfType(); // Iterating over the requested function calls and invoking them. foreach (FunctionCallContent functionCall in functionCalls) { FunctionResultContent? result = null; try { result = await functionCall.InvokeAsync(kernel); // Resolving the function call in the `Kernel.Plugins` collection and invoking it. } catch(Exception ex) { chatHistory.Add(new FunctionResultContent(functionCall, ex).ToChatMessage()); // or //string message = "Error details that LLM can reason about."; //chatHistory.Add(new FunctionResultContent(functionCall, message).ToChatMessageContent()); continue; } chatHistory.Add(result.ToChatMessage()); // or chatHistory.Add(new ChatMessageContent(AuthorRole.Tool, new ChatMessageContentItemCollection() { result })); } // Sending chat history containing function calls and function results to the LLM to get the final response messageContent = await completionService.GetChatMessageContentAsync(chatHistory, settings, kernel); ``` The design does not require callers to create an instance of chat message for each function result content. Instead, it allows multiple instances of the function result content to be sent to the connector through a single instance of chat message: ```csharp ChatMessageContent messageContent = await completionService.GetChatMessageContentAsync(chatHistory, settings, kernel); chatHistory.Add(messageContent); // Adding original chat message content containing function call(s) to the chat history. IEnumerable functionCalls = FunctionCallContent.GetFunctionCalls(messageContent); // Getting list of function calls. ChatMessageContentItemCollection items = new ChatMessageContentItemCollection(); // Iterating over the requested function calls and invoking them foreach (FunctionCallContent functionCall in functionCalls) { FunctionResultContent result = await functionCall.InvokeAsync(kernel); items.Add(result); } chatHistory.Add(new ChatMessageContent(AuthorRole.Tool, items); // Sending chat history containing function calls and function results to the LLM to get the final response messageContent = await completionService.GetChatMessageContentAsync(chatHistory, settings, kernel); ``` ### Decision Outcome Option 1.2 was chosen due to its explicit nature. ## 2. Function calling protocol for chat completion connectors Different chat completion connectors may communicate function calls to the caller and expect function results to be sent back via messages with a connector-specific role. For example, the `{Azure}OpenAIChatCompletionService` connectors use messages with an `Assistant` role to communicate function calls to the connector caller and expect the caller to return function results via messages with a `Tool` role. The role of a function call message returned by a connector is not important to the caller, as the list of functions can easily be obtained by calling the `GetFunctionCalls` method, regardless of the role of the response message. ```csharp ChatMessageContent messageContent = await completionService.GetChatMessageContentAsync(chatHistory, settings, kernel); IEnumerable functionCalls = FunctionCallContent.GetFunctionCalls(); // Will return list of function calls regardless of the role of the messageContent if the content contains the function calls. ``` However, having only one connector-agnostic role for messages to send the function result back to the connector is important for polymorphic usage of connectors. This would allow callers to write code like this: ```csharp ... IEnumerable functionCalls = FunctionCallContent.GetFunctionCalls(); foreach (FunctionCallContent functionCall in functionCalls) { FunctionResultContent result = await functionCall.InvokeAsync(kernel); chatHistory.Add(result.ToChatMessage()); } ... ``` and avoid code like this: ```csharp IChatCompletionService chatCompletionService = new(); ... IEnumerable functionCalls = FunctionCallContent.GetFunctionCalls(); foreach (FunctionCallContent functionCall in functionCalls) { FunctionResultContent result = await functionCall.InvokeAsync(kernel); // Using connector-specific roles instead of a single connector-agnostic one to send results back to the connector would prevent the polymorphic usage of connectors and force callers to write if/else blocks. if(chatCompletionService is OpenAIChatCompletionService || chatCompletionService is AzureOpenAIChatCompletionService) { chatHistory.Add(new ChatMessageContent(AuthorRole.Tool, new ChatMessageContentItemCollection() { result }); } else if(chatCompletionService is AnotherCompletionService) { chatHistory.Add(new ChatMessageContent(AuthorRole.Function, new ChatMessageContentItemCollection() { result }); } else if(chatCompletionService is SomeOtherCompletionService) { chatHistory.Add(new ChatMessageContent(AuthorRole.ServiceSpecificRole, new ChatMessageContentItemCollection() { result }); } } ... ``` ### Decision Outcome It was decided to go with the `AuthorRole.Tool` role because it is well-known, and conceptually, it can represent function results as well as any other tools that SK will need to support in the future. ## 3. Type of FunctionResultContent.Result property: There are a few data types that can be used for the `FunctionResultContent.Result` property. The data type in question should allow the following scenarios: - Be serializable/deserializable, so that it's possible to serialize chat history containing function result content and rehydrate it later when needed. - It should be possible to communicate function execution failure either by sending the original exception or a string describing the problem to LLM. So far, three potential data types have been identified: object, string, and FunctionResult. ### Option 3.1 - object ```csharp class FunctionResultContent : KernelContent { // Other members are omitted public object? Result {get; set;} } ``` This option may require the use of JSON converters/resolvers for the {de}serialization of chat history, which contains function results represented by types not supported by JsonSerializer by default. **Pros**: - Serialization is performed by the connector, but it can also be done by the caller if necessary. - The caller can provide additional data, along with the function result, if needed. - The caller has control over how to communicate function execution failure: either by passing an instance of an Exception class or by providing a string description of the problem to LLM. **Cons**: ### Option 3.2 - string (current implementation) ```csharp class FunctionResultContent : KernelContent { // Other members are omitted public string? Result {get; set;} } ``` **Pros**: - No convertors are required for chat history {de}serialization. - The caller can provide additional data, along with the function result, if needed. - The caller has control over how to communicate function execution failure: either by passing serialized exception, its message or by providing a string description of the problem to LLM. **Cons**: - Serialization is performed by the caller. It can be problematic for polymorphic usage of chat completion service. ### Option 3.3 - FunctionResult ```csharp class FunctionResultContent : KernelContent { // Other members are omitted public FunctionResult? Result {get;set;} public Exception? Exception {get;set} or public object? Error { get; set; } // Can contain either an instance of an Exception class or a string describing the problem. } ``` **Pros**: - Usage of FunctionResult SK domain class. **Cons**: - It is not possible to communicate an exception to the connector/LLM without the additional Exception/Error property. - `FunctionResult` is not {de}serializable today: * The `FunctionResult.ValueType` property has a `Type` type that is not serializable by JsonSerializer by default, as it is considered dangerous. * The same applies to `KernelReturnParameterMetadata.ParameterType` and `KernelParameterMetadata.ParameterType` properties of type `Type`. * The `FunctionResult.Function` property is not deserializable and should be marked with the [JsonIgnore] attribute. * A new constructor, ctr(object? value = null, IReadOnlyDictionary? metadata = null), needs to be added for deserialization. * The `FunctionResult.Function` property has to be nullable. It can be a breaking change? for the function filter users because the filters use `FunctionFilterContext` class that expose an instance of kernel function via the `Function` property. ### Option 3.4 - FunctionResult: KernelContent Note: This option was suggested during a second round of review of this ADR. This option suggests making the `FunctionResult` class a derivative of the `KernelContent` class: ```csharp public class FunctionResult : KernelContent { .... } ``` So, instead of having a separate `FunctionResultContent` class to represent the function result content, the `FunctionResult` class will inherit from the `KernelContent` class, becoming the content itself. As a result, the function result returned by the `KernelFunction.InvokeAsync` method can be directly added to the `ChatMessageContent.Items` collection: ```csharp foreach (FunctionCallContent functionCall in functionCalls) { FunctionResult result = await functionCall.InvokeAsync(kernel); chatHistory.Add(new ChatMessageContent(AuthorRole.Tool, new ChatMessageContentItemCollection { result })); // instead of chatHistory.Add(new ChatMessageContent(AuthorRole.Tool, new ChatMessageContentItemCollection { new FunctionResultContent(functionCall, result) })); // of cause, the syntax can be simplified by having additional instance/extension methods chatHistory.AddFunctionResultMessage(result); // Using the new AddFunctionResultMessage extension method of ChatHistory class } ``` Questions: - How to pass the original `FunctionCallContent` to connectors along with the function result. It's actually not clear atm whether it's needed or not. The current rationale is that some models might expect properties of the original function call, such as arguments, to be passed back to the LLM along with the function result. An argument can be made that the original function call can be found in the chat history by the connector if needed. However, a counterargument is that it may not always be possible because the chat history might be truncated to save tokens, reduce hallucination, etc. - How to pass function id to connector? - How to communicate exception to the connectors? It was proposed to add the `Exception` property the the `FunctionResult` class that will always be assigned by the `KernelFunction.InvokeAsync` method. However, this change will break C# function calling semantic, where the function should be executed if the contract is satisfied, or an exception should be thrown if the contract is not fulfilled. - If `FunctionResult` becomes a non-steaming content by inheriting `KernelContent` class, how the `FunctionResult` can represent streaming content capabilities represented by the `StreamingKernelContent` class when/if it needed later? C# does not support multiple inheritance. **Pros** - The `FunctionResult` class becomes a content(non-streaming one) itself and can be passed to all the places where content is expected. - No need for the extra `FunctionResultContent` class . **Cons** - Unnecessarily coupling between the `FunctionResult` and `KernelContent` classes might be a limiting factor preventing each one from evolving independently as they otherwise could. - The `FunctionResult.Function` property needs to be changed to nullable in order to be serializable, or custom serialization must be applied to {de}serialize the function schema without the function instance itself. - The `Id` property should be added to the `FunctionResult` class to represent the function ID required by LLMs. - ### Decision Outcome Originally, it was decided to go with Option 3.1 because it's the most flexible one comparing to the other two. In case a connector needs to get function schema, it can easily be obtained from kernel.Plugins collection available to the connector. The function result metadata can be passed to the connector through the `KernelContent.Metadata` property. However, during the second round of review for this ADR, Option 3.4 was suggested for exploration. Finally, after prototyping Option 3.4, it was decided to return to Option 3.1 due to the cons of Option 3.4. ## 4. Simulated functions There are cases when LLM ignores data provided in the prompt due to the model's training. However, the model can work with the same data if it is provided to the model via a function result. There are a few ways the simulated function can be modeled: ### Option 4.1 - Simulated function as SemanticFunction ```csharp ... ChatMessageContent messageContent = await completionService.GetChatMessageContentAsync(chatHistory, settings, kernel); // Simulated function call FunctionCallContent simulatedFunctionCall = new FunctionCallContent(name: "weather-alert", id: "call_123"); messageContent.Items.Add(simulatedFunctionCall); // Adding a simulated function call to the connector response message chatHistory.Add(messageContent); // Creating SK function and invoking it KernelFunction simulatedFunction = KernelFunctionFactory.CreateFromMethod(() => "A Tornado Watch has been issued, with potential for severe ..... Stay informed and follow safety instructions from authorities."); FunctionResult simulatedFunctionResult = await simulatedFunction.InvokeAsync(kernel); chatHistory.Add(new ChatMessageContent(AuthorRole.Tool, new ChatMessageContentItemCollection() { new FunctionResultContent(simulatedFunctionCall, simulatedFunctionResult) })); messageContent = await completionService.GetChatMessageContentAsync(chatHistory, settings, kernel); ... ``` **Pros**: - SK function filters/hooks can be triggered when the caller invoke the simulated function. **Cons**: - Not as light-weight as the other option. ### Option 4.2 - object as simulated function ```csharp ... ChatMessageContent messageContent = await completionService.GetChatMessageContentAsync(chatHistory, settings, kernel); // Simulated function FunctionCallContent simulatedFunctionCall = new FunctionCallContent(name: "weather-alert", id: "call_123"); messageContent.Items.Add(simulatedFunctionCall); chatHistory.Add(messageContent); // Creating simulated result string simulatedFunctionResult = "A Tornado Watch has been issued, with potential for severe ..... Stay informed and follow safety instructions from authorities." //or WeatherAlert simulatedFunctionResult = new WeatherAlert { Id = "34SD7RTYE4", Text = "A Tornado Watch has been issued, with potential for severe ..... Stay informed and follow safety instructions from authorities." }; chatHistory.Add(new ChatMessageContent(AuthorRole.Tool, new ChatMessageContentItemCollection() { new FunctionResultContent(simulatedFunctionCall, simulatedFunctionResult) })); messageContent = await completionService.GetChatMessageContentAsync(chatHistory, settings, kernel); ... ``` **Pros**: - A lighter option comparing to the previous one because no SK function creation and execution required. **Cons**: - SK function filters/hooks can't be triggered when the caller invoke the simulated function. ### Decision Outcome The provided options are not mutually exclusive; each can be used depending on the scenario. ## 5. Streaming The design of a service-agnostic function calling model for connectors' streaming API should be similar to the non-streaming one described above. The streaming API differs from a non-streaming one in that the content is returned in chunks rather than all at once. For instance, OpenAI connectors currently return function calls in two chunks: the function id and name come in the first chunk, while the function arguments are sent in subsequent chunks. Furthermore, LLM may stream function calls for more than one function in the same response. For example, the first chunk streamed by a connector may have the id and name of the first function, and the following chunk will have the id and name of the second function. This will require slight deviations in the design of the function-calling model for the streaming API to more naturally accommodate the streaming specifics. In the case of a significant deviation, a separate ADR will be created to outline the details. ================================================ FILE: docs/decisions/0042-samples-restructure.md ================================================ --- # Reestructure of How Sample Code will be Structured In the Repository status: accepted contact: rogerbarreto date: 2024-04-18 deciders: rogerbarreto, markwallace-microsoft, sophialagerkranspandey, matthewbolanos consulted: dmytrostruk, sergeymenshik, westey-m, eavanvalkenburg informed: --- ## Context and Problem Statement - The current way the samples are structured are not very informative and not easy to be found. - Numbering in Kernel Syntax Examples lost its meaning. - Naming of the projects don't sends a clear message what they really are. - Folders and Solutions have `Examples` suffixes which are not necessary as everything in `samples` is already an `example`. ### Current identified types of samples | Type | Description | | ---------------- | -------------------------------------------------------------------------------------------------------- | | `GettingStarted` | A single step-by-step tutorial to get started | | `Concepts` | A concept by feature specific code snippets | | `LearnResources` | Code snippets that are related to online documentation sources like Microsoft Learn, DevBlogs and others | | `Tutorials` | More in depth step-by-step tutorials | | `Demos` | Demonstration applications that leverage the usage of one or many features | ## Decision Drivers and Principles - **Easy to Search**: Well organized structure, making easy to find the different types of samples - **Lean namings**: Folder, Solution and Example names are as clear and as short as possible - **Sends a Clear Message**: Avoidance of Semantic Kernel specific therms or jargons - **Cross Language**: The sample structure will be similar on all supported SK languages. ## Strategy on the current existing folders | Current Folder | Proposal | | ------------------------------------ | ------------------------------------------------------------------- | | KernelSyntaxExamples/Getting_Started | Move into `GettingStarted` | | KernelSyntaxExamples/`Examples??_*` | Decompose into `Concepts` on multiple conceptual subfolders | | AgentSyntaxExamples | Decompose into `Concepts` on `Agents` specific subfolders. | | DocumentationExamples | Move into `LearnResources` subfolder and rename to `MicrosoftLearn` | | CreateChatGptPlugin | Move into `Demo` subfolder | | HomeAutomation | Move into `Demo` subfolder | | TelemetryExample | Move into `Demo` subfolder and rename to `TelemetryWithAppInsights` | | HuggingFaceImageTextExample | Move into `Demo` subfolder and rename to `HuggingFaceImageToText` | ## Considered Root Structure Options The following options below are the potential considered options for the root structure of the `samples` folder. ### Option 1 - Ultra Narrow Root Categorization This option squeezes as much as possible the root of `samples` folder in different subcategories to be minimalist when looking for the samples. Proposed root structure ``` samples/ ├── Tutorials/ │ └── Getting Started/ ├── Concepts/ │ ├── Kernel Syntax** │ └── Agents Syntax** ├── Resources/ └── Demos/ ``` Pros: - Simpler and Less verbose structure (Worse is Better: Less is more approach) - Beginners will be presented (sibling folders) to other tutorials that may fit better on their need and use case. - Getting started will not be imposed. Cons: - May add extra cognitive load to know that `Getting Started` is a tutorial ### Option 2 - Getting Started Root Categorization This option brings `Getting Started` to the root `samples` folder compared the structure proposed in `Option 1`. Proposed root structure ``` samples/ ├── Getting Started/ ├── Tutorials/ ├── Concepts/ │ ├── Kernel Syntax Decomposition** │ └── Agents Syntax Decomposition** ├── Resources/ └── Demos/ ``` Pros: - Getting Started is the first thing the customer will see - Beginners will need an extra click to get started. Cons: - If the Getting started example does not have a valid example for the customer it has go back on other folders for more content. ### Option 3 - Conservative + Use Cases Based Root Categorization This option is more conservative and keeps Syntax Examples projects as root options as well as some new folders for Use Cases, Modalities and Kernel Content. Proposed root structure ``` samples/ |── QuickStart/ |── Tutorials/ ├── KernelSyntaxExamples/ ├── AgentSyntaxExamples/ ├── UseCases/ OR Demos/ ├── KernelContent/ OR Modalities/ ├── Documentation/ OR Resources/ ``` Pros: - More conservative approach, keeping KernelSyntaxExamples and AgentSyntaxExamples as root folders won't break any existing internet links. - Use Cases, Modalities and Kernel Content are more specific folders for different types of samples Cons: - More verbose structure adds extra friction to find the samples. - `KernelContent` or `Modalities` is a internal term that may not be clear for the customer - `Documentation` may be confused a documents only folder, which actually contains code samples used in documentation. (not clear message) - `Use Cases` may suggest an idea of real world use cases implemented, where in reality those are simple demonstrations of a SK feature. ## KernelSyntaxExamples Decomposition Options Currently Kernel Syntax Examples contains more than 70 numbered examples all side-by-side, where the number has no progress meaning and is not very informative. The following options are considered for the KernelSyntaxExamples folder decomposition over multiple subfolders based on Kernel `Concepts` and Features that were developed. Identified Component Oriented Concepts: - Kernel - Builder - Functions - Arguments - MethodFunctions - PromptFunctions - Types - Results - Serialization - Metadata - Strongly typed - InlineFunctions - Plugins - Describe Plugins - OpenAI Plugins - OpenAPI Plugins - API Manifest - gRPC Plugins - Mutable Plugins - AI Services (Examples using Services thru Kernel Invocation) - Chat Completion - Text Generation - Service Selector - Hooks - Filters - Function Filtering - Template Rendering Filtering - Function Call Filtering (When available) - Templates - AI Services (Examples using Services directly with Single/Multiple + Streaming and Non-Streaming results) - ExecutionSettings - Chat Completion - Local Models - Ollama - HuggingFace - LMStudio - LocalAI - Gemini - OpenAI - AzureOpenAI - HuggingFace - Text Generation - Local Models - Ollama - HuggingFace - OpenAI - AzureOpenAI - HuggingFace - Text to Image - OpenAI - AzureOpenAI - Image to Text - HuggingFace - Text to Audio - OpenAI - Audio to Text - OpenAI - Custom - DYI - OpenAI - OpenAI File - Memory Services - Search - Semantic Memory - Text Memory - Azure AI Search - Text Embeddings - OpenAI - HuggingFace - Telemetry - Logging - Dependency Injection - HttpClient - Resiliency - Usage - Planners - Handlerbars - Authentication - Azure AD - Function Calling - Auto Function Calling - Manual Function Calling - Filtering - Kernel Hooks - Service Selector - Templates - Resilience - Memory - Semantic Memory - Text Memory Plugin - Search - RAG - Inline - Function Calling - Agents - Delegation - Charts - Collaboration - Authoring - Tools - Chat Completion Agent (Agent Syntax Examples Goes here without numbering) - Flow Orchestrator ### KernelSyntaxExamples Decomposition Option 1 - Concept by Components This options decomposes the Concepts Structured by Kernel Components and Features. At first is seems logical and easy to understand how the concepts are related and can be evolved into more advanced concepts following the provided structure.

Feel free to remove any of them. status: accepted contact: dmytrostruk date: 2024-04-24 deciders: sergeymenshykh, markwallace, rbarreto, dmytrostruk, stoub --- # Exception handling in filters ## Context and Problem Statement In .NET version of Semantic Kernel, when kernel function throws an exception, it will be propagated through execution stack until some code will catch it. To handle exception for `kernel.InvokeAsync(function)`, this code should be wrapped in `try/catch` block, which is intuitive approach how to deal with exceptions. Unfortunately, `try/catch` block is not useful for auto function calling scenario, when a function is called based on some prompt. In this case, when function throws an exception, message `Error: Exception while invoking function.` will be added to chat history with `tool` author role, which should provide some context to LLM that something went wrong. There is a requirement to have the ability to override function result - instead of throwing an exception and sending error message to AI, it should be possible to set some custom result, which should allow to control LLM behavior. ## Considered Options ### [Option 1] Add new method to existing `IFunctionFilter` interface Abstraction: ```csharp public interface IFunctionFilter { void OnFunctionInvoking(FunctionInvokingContext context); void OnFunctionInvoked(FunctionInvokedContext context); // New method void OnFunctionException(FunctionExceptionContext context); } ``` Disadvantages: - Adding new method to existing interface will be a breaking change, as it will force current filter users to implement new method. - This method will be always required to implement when using function filters, even when exception handling is not needed. On the other hand, this method won't return anything, so it could remain always empty, or with .NET multitargeting, it should be possible to define default implementation for C# 8 and above. ### [Option 2] Introduce new `IExceptionFilter` interface New interface will allow to receive exception objects, cancel exception or rethrowing new type of exception. This option can be also added later as filter on a higher level for global exception handling. Abstraction: ```csharp public interface IExceptionFilter { // ExceptionContext class will contain information about actual exception, kernel function etc. void OnException(ExceptionContext context); } ``` Usage: ```csharp public class MyFilter : IFunctionFilter, IExceptionFilter { public void OnFunctionInvoking(FunctionInvokingContext context) { } public void OnFunctionInvoked(FunctionInvokedContext context) { } public void OnException(ExceptionContext context) {} } ``` Advantages: - It's not a breaking change, and all exception handling logic should be added on top of existing filter mechanism. - Similar to `IExceptionFilter` API in ASP.NET. Disadvantages: - It may be not intuitive and hard to remember, that for exception handling, separate interface should be implemented. ### [Option 3] Extend Context model in existing `IFunctionFilter` interface In `IFunctionFilter.OnFunctionInvoked` method, it's possible to extend `FunctionInvokedContext` model by adding `Exception` property. In this case, as soon as `OnFunctionInvoked` is triggered, it will be possible to observe whether there was an exception during function execution. If there was an exception, users could do nothing and the exception will be thrown as usual, which means that in order to handle it, function invocation should be wrapped with `try/catch` block. But it will be also possible to cancel that exception and override function result, which should provide more control over function execution and what is passed to LLM. Abstraction: ```csharp public sealed class FunctionInvokedContext : FunctionFilterContext { // other properties... public Exception? Exception { get; private set; } } ``` Usage: ```csharp public class MyFilter : IFunctionFilter { public void OnFunctionInvoking(FunctionInvokingContext context) { } public void OnFunctionInvoked(FunctionInvokedContext context) { // This means that exception occurred during function execution. // If we ignore it, the exception will be thrown as usual. if (context.Exception is not null) { // Possible options to handle it: // 1. Do not throw an exception that occurred during function execution context.Exception = null; // 2. Override the result with some value, that is meaningful to LLM context.Result = new FunctionResult(context.Function, "Friendly message instead of exception"); // 3. Rethrow another type of exception if needed - Option 1. context.Exception = new Exception("New exception"); // 3. Rethrow another type of exception if needed - Option 2. throw new Exception("New exception"); } } } ``` Advantages: - Requires minimum changes to existing implementation and also it won't break existing filter users. - Similar to `IActionFilter` API in ASP.NET. - Scalable, because it will be possible to extend similar Context models for other type of filters when needed (prompt or function calling filters). Disadvantages: - Not .NET-friendly way of exception handling with `context.Exception = null` or `context.Exception = new AnotherException()`, instead of using native `try/catch` approach. ### [Option 4] Change `IFunctionFilter` signature by adding `next` delegate. This approach changes the way how filters work at the moment. Instead of having two `Invoking` and `Invoked` methods in filter, there will be only one method that will be invoked during function execution with `next` delegate, which will be responsible to call next registered filter in pipeline or function itself, in case there are no remaining filters. Abstraction: ```csharp public interface IFunctionFilter { Task OnFunctionInvocationAsync(FunctionInvocationContext context, Func next); } ``` Usage: ```csharp public class MyFilter : IFunctionFilter { public async Task OnFunctionInvocationAsync(FunctionInvocationContext context, Func next) { // Perform some actions before function invocation await next(context); // Perform some actions after function invocation } } ``` Exception handling with native `try/catch` approach: ```csharp public async Task OnFunctionInvocationAsync(FunctionInvocationContext context, Func next) { try { await next(context); } catch (Exception exception) { this._logger.LogError(exception, "Something went wrong during function invocation"); // Example: override function result value context.Result = new FunctionResult(context.Function, "Friendly message instead of exception"); // Example: Rethrow another type of exception if needed throw new InvalidOperationException("New exception"); } } ``` Advantages: - Native way how to handle and rethrow exceptions. - Similar to `IAsyncActionFilter` and `IEndpointFilter` API in ASP.NET. - One filter method to implement instead of two (`Invoking/Invoked`) - this allows to keep invocation context information in one method instead of storing it on class level. For example, to measure function execution time, `Stopwatch` can be created and started before `await next(context)` call and used after the call, while in approach with `Invoking/Invoked` methods the data should be passed between filter actions in other way, for example setting it on class level, which is harder to maintain. - No need in cancellation logic (e.g. `context.Cancel = true`). To cancel the operation, simply don't call `await next(context)`. Disadvantages: - Remember to call `await next(context)` manually in all filters. If it's not called, next filter in pipeline and/or function itself won't be called. ## Decision Outcome Proceed with Option 4 and apply this approach to function, prompt and function calling filters. ================================================ FILE: docs/decisions/0044-OTel-semantic-convention.md ================================================ --- # These are optional elements.

This work aims to ensure that SK provides the best developer experience while complying with the industry standards for observability in generative-AI-based applications. For more information, please refer to this issue: https://github.com/open-telemetry/semantic-conventions/issues/327 ### Semantic conventions The semantic conventions for generative AI are currently in their nascent stage, and as a result, many of the requirements outlined here may undergo changes in the future. Consequently, several features derived from this Architectural Decision Record (ADR) may be considered experimental. It is essential to remain adaptable and responsive to evolving industry standards to ensure the continuous improvement of our system's performance and reliability. - [Semantic conventions for generative AI](https://github.com/open-telemetry/semantic-conventions/tree/main/docs/gen-ai) - [Generic LLM attributes](https://github.com/open-telemetry/semantic-conventions/blob/main/docs/attributes-registry/gen-ai.md) ### Telemetry requirements (Experimental) Based on the [initial version](https://github.com/open-telemetry/semantic-conventions/blob/651d779183ecc7c2f8cfa90bf94e105f7b9d3f5a/docs/attributes-registry/gen-ai.md), Semantic Kernel should provide the following attributes in activities that represent individual LLM requests: > `Activity` is a .Net concept and existed before OpenTelemetry. A `span` is an OpenTelemetry concept that is equivalent to an `Activity`. - (Required)`gen_ai.system` - (Required)`gen_ai.request.model` - (Recommended)`gen_ai.request.max_token` - (Recommended)`gen_ai.request.temperature` - (Recommended)`gen_ai.request.top_p` - (Recommended)`gen_ai.response.id` - (Recommended)`gen_ai.response.model` - (Recommended)`gen_ai.response.finish_reasons` - (Recommended)`gen_ai.response.prompt_tokens` - (Recommended)`gen_ai.response.completion_tokens` The following events will be optionally attached to an activity: | Event name| Attribute(s)| |---|---| |`gen_ai.content.prompt`|`gen_ai.prompt`| |`gen_ai.content.completion`|`gen_ai.completion`| > The kernel must provide configuration options to disable these events because they may contain PII. > See the [Semantic conventions for generative AI](https://github.com/open-telemetry/semantic-conventions/tree/main/docs/gen-ai) for requirement level for these attributes. ## Where do we create the activities It is crucial to establish a clear line of responsibilities, particularly since certain service providers, such as the Azure OpenAI SDK, have pre-existing instrumentation. Our objective is to position our activities as close to the model level as possible to promote a more cohesive and consistent developer experience. ```mermaid block-beta columns 1 Models blockArrowId1<["   "]>(y) block:Clients columns 3 ConnectorTypeClientA["Instrumented client SDK
(i.e. Azure OpenAI client)"] ConnectorTypeClientB["Un-instrumented Client SDK"] ConnectorTypeClientC["Custom client on REST API
(i.e. HuggingFaceClient)"] end Connectors["AI Connectors"] blockArrowId2<["   "]>(y) SemanticKernel["Semantic Kernel"] block:Kernel Function Planner Agent end ``` > Semantic Kernel also supports other types of connectors for memories/vector databases. We will discuss instrumentations for those connectors in a separate ADR. > Note that this will not change our approaches to [instrumentation for planners and kernel functions](./0025-planner-telemetry-enhancement.md). We may modify or remove some of the meters we created previously, which will introduce breaking changes. In order to keep the activities as close to the model level as possible, we should keep them at the connector level. ### Out of scope These services will be discuss in the future: - Memory/vector database services - Audio to text services (`IAudioToTextService`) - Embedding services (`IEmbeddingGenerationService`) - Image to text services (`IImageToTextService`) - Text to audio services (`ITextToAudioService`) - Text to image services (`ITextToImageService`) ## Considered Options - Scope of Activities - All connectors, irrespective of the client SDKs used. - Connectors that either lack instrumentation in their client SDKs or use custom clients. - All connectors, noting that the attributes of activities derived from connectors and those from instrumented client SDKs do not overlap. - Implementations of Instrumentation - Static class - Switches for experimental features and the collection of sensitive data - App context switch ### Scope of Activities #### All connectors, irrespective of the client SDKs utilized All AI connectors will generate activities for the purpose of tracing individual requests to models. Each activity will maintain a **consistent set of attributes**. This uniformity guarantees that users can monitor their LLM requests consistently, irrespective of the connectors used within their applications. However, it introduces the potential drawback of data duplication which **leads to greater costs**, as the attributes contained within these activities will encompass a broader set (i.e. additional SK-specific attributes) than those generated by the client SDKs, assuming that the client SDKs are likewise instrumented in alignment with the semantic conventions. > In an ideal world, it is anticipated that all client SDKs will eventually align with the semantic conventions. #### Connectors that either lack instrumentation in their client SDKs or utilize custom clients AI connectors paired with client SDKs that lack the capability to generate activities for LLM requests will take on the responsibility of creating such activities. In contrast, connectors associated with client SDKs that do already generate request activities will not be subject to further instrumentation. It is required that users subscribe to the activity sources offered by the client SDKs to ensure consistent tracking of LLM requests. This approach helps in **mitigating the costs** associated with unnecessary data duplication. However, it may introduce **inconsistencies in tracing**, as not all LLM requests will be accompanied by connector-generated activities. #### All connectors, noting that the attributes of activities derived from connectors and those from instrumented client SDKs do not overlap All connectors will generate activities for the purpose of tracing individual requests to models. The composition of these connector activities, specifically the attributes included, will be determined based on the instrumentation status of the associated client SDK. The aim is to include only the necessary attributes to prevent data duplication. Initially, a connector linked to a client SDK that lacks instrumentation will generate activities encompassing all potential attributes as outlined by the LLM semantic conventions, alongside some SK-specific attributes. However, once the client SDK becomes instrumented in alignment with these conventions, the connector will cease to include those previously added attributes in its activities, avoiding redundancy. This approach facilitates a **relatively consistent** development experience for user building with SK while **optimizing costs** associated with observability. ### Instrumentation implementations #### Static class `ModelDiagnostics` This class will live under `dotnet\src\InternalUtilities\src\Diagnostics`. ```C# // Example namespace Microsoft.SemanticKernel; internal static class ModelDiagnostics { public static Activity? StartCompletionActivity( string name, string modelName, string modelProvider, string prompt, PromptExecutionSettings? executionSettings) { ... } // Can be used for both non-streaming endpoints and streaming endpoints. // For streaming, collect a list of `StreamingTextContent` and concatenate them into a single `TextContent` at the end of the streaming. public static void SetCompletionResponses( Activity? activity, IEnumerable completions, int promptTokens, int completionTokens, IEnumerable? finishReasons) { ... } // Contains more methods for chat completion and other services ... } ``` Example usage ```C# public async Task> GenerateTextAsync( string prompt, PromptExecutionSettings? executionSettings, CancellationToken cancellationToken) { using var activity = ModelDiagnostics.StartCompletionActivity( $"text.generation {this._modelId}", this._modelId, "HuggingFace", prompt, executionSettings); var completions = ...; var finishReasons = ...; // Usage can be estimated. var promptTokens = ...; var completionTokens = ...; ModelDiagnostics.SetCompletionResponses( activity, completions, promptTokens, completionTokens, finishReasons); return completions; } ``` ### Switches for experimental features and the collection of sensitive data #### App context switch We will introduce two flags to facilitate the explicit activation of tracing LLMs requests: 1. `Microsoft.SemanticKernel.Experimental.EnableModelDiagnostics` - Activating will enable the creation of activities that represent individual LLM requests. 2. `Microsoft.SemanticKernel.Experimental.EnableModelDiagnosticsWithSensitiveData` - Activating will enable the creation of activities that represent individual LLM requests, with events that may contain PII information. ```C# // In application code if (builder.Environment.IsProduction()) { AppContext.SetSwitch("Microsoft.SemanticKernel.Experimental.EnableModelDiagnostics", true); } else { AppContext.SetSwitch("Microsoft.SemanticKernel.Experimental.EnableModelDiagnosticsWithSensitiveData", true); } // Or in the project file ``` ## Decision Outcome Chosen options: [x] Scope of Activities: **Option 3** - All connectors, noting that the attributes of activities derived from connectors and those from instrumented client SDKs do not overlap. [x] Instrumentation Implementation: **Option 1** - Static class [x] Experimental switch: **Option 1** - App context switch ## Appendix ### `AppContextSwitchHelper.cs` ```C# internal static class AppContextSwitchHelper { public static bool GetConfigValue(string appContextSwitchName) { if (AppContext.TryGetSwitch(appContextSwitchName, out bool value)) { return value; } return false; } } ``` ### `ModelDiagnostics` ```C# internal static class ModelDiagnostics { // Consistent namespace for all connectors private static readonly string s_namespace = typeof(ModelDiagnostics).Namespace; private static readonly ActivitySource s_activitySource = new(s_namespace); private const string EnableModelDiagnosticsSettingName = "Microsoft.SemanticKernel.Experimental.GenAI.EnableOTelDiagnostics"; private const string EnableSensitiveEventsSettingName = "Microsoft.SemanticKernel.Experimental.GenAI.EnableOTelDiagnosticsSensitive"; private static readonly bool s_enableSensitiveEvents = AppContextSwitchHelper.GetConfigValue(EnableSensitiveEventsSettingName); private static readonly bool s_enableModelDiagnostics = AppContextSwitchHelper.GetConfigValue(EnableModelDiagnosticsSettingName) || s_enableSensitiveEvents; public static Activity?

StartActivityWithTags(this ActivitySource source, string name, List> tags) { return source.StartActivity( name, ActivityKind.Internal, Activity.Current?.Context ?? new ActivityContext(), tags); } public static Activity EnrichAfterResponse(this Activity activity, List> tags) { tags.ForEach(tag => { if (tag.Value is not null) { activity.SetTag(tag.Key, tag.Value); } }); } public static Activity AttachSensitiveDataAsEvent(this Activity activity, string name, List> tags) { activity.AddEvent(new ActivityEvent( name, tags: new ActivityTagsCollection(tags) )); return activity; } } ``` > Please be aware that the implementations provided above serve as illustrative examples, and the actual implementations within the codebase may undergo modifications. ================================================ FILE: docs/decisions/0045-breaking-changes-guidance.md ================================================ --- status: accepted contact: markwallace date: 2024-06-10 deciders: sergeymenshykh, mbolan, rbarreto, dmytrostruk, westey consulted: informed: --- # Guidance for Breaking Changes ## Context and Problem Statement We must avoid breaking changes in .Net because of the well known [diamond dependency issue](https://learn.microsoft.com/en-us/dotnet/standard/library-guidance/dependencies#diamond-dependencies) where breaking changes between different versions of the same package cause bugs and exceptions at run time. ## Decision Drivers Breaking changes are only allowed under the following circumstances: - Updates to an experimental feature i.e. we have learnt something new and need to modify the design of an experimental feature. - When one of our dependencies introduces an unavoidable breaking change. All breaking changes must be clearly documented, definitely in the release notes and possibly also via a migration guide Blog post. - Include a detailed description of the breaking change in the PR description so that it is included in the release notes. - Update Learn Site migration guide documentation and have this published to coincide with the release which includes the breaking change. In all other cases we must avoid breaking changes. There will be situations where we need to move to accommodate a change to one of our dependencies or introduce a new capability e.g. - When we find a security issue or a severe bug (e.g. data loss). - One of our dependencies introduces a major breaking change e.g. the introduction of the new OpenAI SDK. - When we find a severe limitation in our current implementation e.g. when the AI services introduce a new capability. In these cases we will plan to obsolete the API(s) and provide a documented migration path to the new preferred pattern. An example of this will be the switch to the new OpenAI .Net SDK. During this transition there will be a period where the new and old API's will be supported to allow customers to migrate. ## Decision Outcome Chosen option: We must avoid breaking changes in .Net because of the well known diamond dependency issue. ================================================ FILE: docs/decisions/0046-azure-model-as-a-service.md ================================================ --- # These are optional elements.

MaaS, which is also referred to as [serverless API](https://learn.microsoft.com/en-us/azure/ai-studio/how-to/model-catalog-overview#model-deployment-managed-compute-and-serverless-api-pay-as-you-go), is available in [Azure AI Studio](https://learn.microsoft.com/en-us/azure/ai-studio/what-is-ai-studio). This mode of consumption operates on a pay-as-you-go basis, typically using tokens for billing purposes. Clients can access the service via the [Azure AI Model Inference API](https://learn.microsoft.com/en-us/azure/ai-studio/reference/reference-model-inference-api?tabs=azure-studio) or client SDKs. At present, there is no official support for MaaS in SK. The purpose of this ADR is to examine the constraints of the service and explore potential solutions to enable support for the service in SK via the development of a new AI connector. ## Client SDK The Azure team will be providing a new client library, namely `Azure.AI.Inference` in .Net and `azure-ai-inference` in Python, for effectively interacting with the service. While the service API is OpenAI-compatible, it is not permissible to use the OpenAI and the Azure OpenAI client libraries for interacting with the service as they are not independent with respect to both the models and their providers. This is because Azure AI Studio features a diverse range of open-source models, other than OpenAI models. ### Limitations The initial release of the client SDK will only support chat completion and text/image embedding generation, with image generation to be added later. Plans to support for text completion are currently unclear, and it is highly unlikely that the SDK will ever include support for text completion. As a result, the new AI connector will **NOT** support text completions in the initial version until we get more customer signals or the client SDK adds support. ## AI Connector ### Naming options - Azure - AzureAI - AzureAIInference - AzureAIModelInference Decision: `AzureAIInference` ### Support for model-specific parameters Models can possess supplementary parameters that are not part of the default API. The service API and the client SDK enable the provision of model-specific parameters. Users can provide model-specific settings via a dedicated argument along with other settings, such as `temperature` and `top_p`, among others. In the context of SK, execution parameters are categorized under `PromptExecutionSettings`, which is inherited by all connector-specific setting classes. The settings of the new connector will contain a member of type `dictionary`, which will group together the model-specific parameters. ================================================ FILE: docs/decisions/0046-java-repository-separation.md ================================================ --- # These are optional elements. Feel free to remove any of them. status: proposed contact: John Oliver date: 2024-06-18 --- # Separate Java Repository To a Separate Code Base ## Context and Problem Statement Managing multiple languages within a single repository provides some challenges with respect to how different languages and their build tools manage repositories. Particularly with respect to how common build tooling for Java, like Apache Maven, interacts with repositories. Typically, while doing a Maven release you want to be able to freeze your repository so that commits are not being added while preparing a release. To achieve this in a shared repository we would effectively need to request all languages halt merging pull requests while we are in this process. The Maven release process also interacts badly with the projects desire for merges to be squashed which for the most part blocks a typical Maven release process that needs to push multiple commits into a repository. Additionally, from a discoverability standpoint, in the original repository the majority of current pull requests, issues and activity are from other languages. This has created some confusion from users about if the semantic kernel repository is the correct repository for Java. Managing git history when performing tasks such as looking at diffs or compiling release notes is also significantly harder when the majority of commits and code are unrelated to Java. Also managing repository policies that are preferred by all languages is a challenge as we have to produce a more complex build process to account for building multiple languages. If a user makes accidental changes to the repository outside their own language, or make changes to the common files, require sign off from other languages, leading to delays as we require review from users in other languages. Similarly common files such as GitHub Actions workflows, `.gitignore`, VS Code settings, `README.md`, `.editorconfig` etc, become more complex as they have to simultaneously support multiple languages. In a community point of view, having a separate repo will foster community engagement, allowing developers to contribute, share ideas, and collaborate on the Java projects only. Additionally, it enables transparent tracking of contributions, making it easy to identify top contributors and acknowledge their efforts. Having a single repository will also provide valuable statistics on commits, pull requests, and other activities, helping maintainers monitor project progress and activity levels. ## Decision Drivers - Allow project settings that are compatible with Java tooling - Improve the communities' ability to discover and interact with the Java project - Improve the ability for the community to observe changes to the Java project in isolation - Simplify repository build/files to concentrate on a single language ## Considered Options We have in the past run out of a separate branch within the [Semantic Kernel](https://github.co/microsoft/semantic-kernel) repository which solved some of the issues however significantly hindered user discoverability as users expect to find the latest code on the main branch. ## Decision Outcome Java repository has been moved to [semantic-kernel-java](https://github.com/microsoft/semantic-kernel-java) ================================================ FILE: docs/decisions/0046-kernel-content-graduation.md ================================================ --- # These are optional elements.

Uri { get; set; } string DataUri { get; set; } bool CanRead { get; } // Indicates if the content can be read as bytes or data uri ctor(Uri? referencedUri) ctor(string dataUri) // MimeType is not optional but nullable to encourage this information to be passed always when available. ctor(ReadOnlyMemory data, string? mimeType) ctor() // Empty ctor for serialization scenarios } ``` - No Content property (Avoid clashing and/or misleading information if used from a specialized type context) i.e: - `PdfContent.Content` (Describe the text only information) - `PictureContent.Content` (Exposes a `Picture` type) - Move away from deferred (lazy loaded) content providers, simpler API. - `GetContentAsync` removal (No more derrefed APIs) - Added `Data` property as setter and getter for byte array content information. Setting this property will override the `DataUri` base64 data part. - Added `DataUri` property as setter and getter for data uri content information. Setting this property will override the `Data` and `MimeType` properties with the current payload details. - Add `Uri` property for referenced content information. This property is does not accept not a `UriData` and only supports non-data schemes. - Add `CanRead` property (To indicate if the content can be read using `Data` or `DataUri` properties.) - Dedicated constructors for Uri, DataUri and ByteArray + MimeType creation. Pros: - With no deferred content we have simpler API and a single responsibility for contents. - Can be written and read in both `Data` or `DataUri` formats. - Can have a `Uri` reference property, which is common for specialized contexts. - Fully serializable. - Data Uri parameters support (serialization included). - Data Uri and Base64 validation checks - Data Uri and Data can be dynamically generated - `CanRead` will clearly identify if the content can be read as `bytes` or `DataUri`. Cons: - Breaking change for experimental `BinaryContent` consumers ### Data Uri Parameters According to [RFC 2397](https://datatracker.ietf.org/doc/html/rfc2397), the data uri scheme supports parameters Every parameter imported from the data uri will be added to the Metadata dictionary with the "data-uri-parameter-name" as key and its respetive value. #### Providing a parameterized data uri will include those parameters in the Metadata dictionary. ```csharp var content = new BinaryContent("data:application/json;parameter1=value1;parameter2=value2;base64,SGVsbG8gV29ybGQ="); var parameter1 = content.Metadata["data-uri-parameter1"]; // value1 var parameter2 = content.Metadata["data-uri-parameter2"]; // value2 ``` #### Deserialization of contents will also include those parameters when getting the DataUri property. ```csharp var json = """ { "metadata": { "data-uri-parameter1":"value1", "data-uri-parameter2":"value2" }, "mimeType":"application/json", "data":"SGVsbG8gV29ybGQ=" } """; var content = JsonSerializer.Deserialize(json); content.DataUri // "data:application/json;parameter1=value1;parameter2=value2;base64,SGVsbG8gV29ybGQ=" ``` ### Specialization Examples #### ImageContent ```csharp public class ImageContent : BinaryContent { ctor(Uri uri) : base(uri) ctor(string dataUri) : base(dataUri) ctor(ReadOnlyMemory data, string? mimeType) : base(data, mimeType) ctor() // serialization scenarios } public class AudioContent : BinaryContent { ctor(Uri uri) } ``` Pros: - Supports data uri large contents - Allows a binary ImageContent to be created using dataUrl scheme and also be referenced by a Url. - Supports Data Uri validation ## ImageContent Graduation ⚠️ Currently this is not experimental, breaking changes needed to be graduated to stable state with potential benefits. ### Problems 1. Current `ImageContent` does not derive from `BinaryContent` 2. Has an undesirable behavior allowing the same instance to have distinct `DataUri` and `Data` at the same time. 3. `Uri` property is used for both data uri and referenced uri information 4. `Uri` does not support large language data uri formats. 5. Not clear to the `sk developer` whenever the content is readable or not. #### Current ```csharp public class ImageContent : KernelContent { Uri? Uri { get; set; } public ReadOnlyMemory? Data { get; set; } ctor(ReadOnlyMemory? data) ctor(Uri uri) ctor() } ``` #### Proposed As already shown in the `BinaryContent` section examples, the `ImageContent` can be graduated to be a `BinaryContent` specialization an inherit all the benefits it brings. ```csharp public class ImageContent : BinaryContent { ctor(Uri uri) : base(uri) ctor(string dataUri) : base(dataUri) ctor(ReadOnlyMemory data, string? mimeType) : base(data, mimeType) ctor() // serialization scenarios } ``` Pros: - Can be used as a `BinaryContent` type - Can be written and read in both `Data` or `DataUri` formats. - Can have a `Uri` dedicated for referenced location. - Fully serializable. - Data Uri parameters support (serialization included). - Data Uri and Base64 validation checks - Can be retrieved - Data Uri and Data can be dynamically generated - `CanRead` will clearly identify if the content can be read as `bytes` or `DataUri`. Cons: - ⚠️ Breaking change for `ImageContent` consumers ### ImageContent Breaking Changes - `Uri` property will be dedicated solely for referenced locations (non-data-uri), attempting to add a `data-uri` format will throw an exception suggesting the usage of the `DataUri` property instead. - Setting `DataUri` will override the `Data` and `MimeType` properties according with the information provided. - Attempting to set an invalid `DataUri` will throw an exception. - Setting `Data` will now override the `DataUri` data part. - Attempting to serialize an `ImageContent` with data-uri in the `Uri` property will throw an exception. ## AudioContent Graduation Similar to `ImageContent` proposal `AudioContent` can be graduated to be a `BinaryContent`. #### Current 1. Current `AudioContent` does not derive support `Uri` referenced location 2. `Uri` property is used for both data uri and referenced uri information 3. `Uri` does not support large language data uri formats. 4. Not clear to the `sk developer` whenever the content is readable or not. ```csharp public class AudioContent : KernelContent { public ReadOnlyMemory? Data { get; set; } ctor(ReadOnlyMemory? data) ctor() } ``` #### Proposed ```csharp public class AudioContent : BinaryContent { ctor(Uri uri) : base(uri) ctor(string dataUri) : base(dataUri) ctor(ReadOnlyMemory data, string? mimeType) : base(data, mimeType) ctor() // serialization scenarios } ``` Pros: - Can be used as a `BinaryContent` type - Can be written and read in both `Data` or `DataUri` formats. - Can have a `Uri` dedicated for referenced location. - Fully serializable. - Data Uri parameters support (serialization included). - Data Uri and Base64 validation checks - Can be retrieved - Data Uri and Data can be dynamically generated - `CanRead` will clearly identify if the content can be read as `bytes` or `DataUri`. Cons: - Experimental breaking change for `AudioContent` consumers ## FunctionCallContent Graduation ### Current No changes needed to current structure. Potentially we could have a base `FunctionContent` but at the same time is good having those two deriving from `KernelContent` providing a clear separation of concerns. ```csharp public sealed class FunctionCallContent : KernelContent { public string? Id { get; } public string? PluginName { get; } public string FunctionName { get; } public KernelArguments? Arguments { get; } public Exception? Exception { get; init; } ctor(string functionName, string? pluginName = null, string? id = null, KernelArguments? arguments = null) public async Task InvokeAsync(Kernel kernel, CancellationToken cancellationToken = default) public static IEnumerable GetFunctionCalls(ChatMessageContent messageContent) } ``` ## FunctionResultContent Graduation It may require some changes although the current structure is good. ### Current - From a purity perspective the `Id` property can lead to confusion as it's not a response Id but a function call Id. - ctors have different `functionCall` and `functionCallContent` parameter names for same type. ```csharp public sealed class FunctionResultContent : KernelContent { public string? Id { get; } public string? PluginName { get; } public string? FunctionName { get; } public object? Result { get; } ctor(string? functionName = null, string? pluginName = null, string? id = null, object? result = null) ctor(FunctionCallContent functionCall, object? result = null) ctor(FunctionCallContent functionCallContent, FunctionResult result) } ``` ### Proposed - Option 1 - Rename `Id` to `CallId` to avoid confusion. - Adjust `ctor` parameters names. ```csharp public sealed class FunctionResultContent : KernelContent { public string? CallId { get; } public string? PluginName { get; } public string? FunctionName { get; } public object? Result { get; } ctor(string? functionName = null, string? pluginName = null, string? callId = null, object? result = null) ctor(FunctionCallContent functionCallContent, object? result = null) ctor(FunctionCallContent functionCallContent, FunctionResult functionResult) } ``` ### Proposed - Option 2 Use composition a have a dedicated CallContent within the `FunctionResultContent`. Pros: - `CallContent` has options to invoke a function again from its response which can be handy for some scenarios - Brings clarity from where the result came from and what is result specific data (root class). - Knowledge about the arguments used in the call. Cons: - Introduce one extra hop to get the `call` details from the result. ```csharp public sealed class FunctionResultContent : KernelContent { public FunctionCallContent CallContent { get; } public object? Result { get; } ctor(FunctionCallContent functionCallContent, object? result = null) ctor(FunctionCallContent functionCallContent, FunctionResult functionResult) } ``` ## FileReferenceContent + AnnotationContent Those two contents were added to `SemanticKernel.Abstractions` due to Serialization convenience but are very specific to **OpenAI Assistant API** and should be kept as Experimental for now. As a graduation those should be into `SemanticKernel.Agents.OpenAI` following the suggestion below. ```csharp #pragma warning disable SKEXP0110 [JsonDerivedType(typeof(AnnotationContent), typeDiscriminator: nameof(AnnotationContent))] [JsonDerivedType(typeof(FileReferenceContent), typeDiscriminator: nameof(FileReferenceContent))] #pragma warning disable SKEXP0110 public abstract class KernelContent { ... } ``` This coupling should not be encouraged for other packages that have `KernelContent` specializations. ### Solution - Usage of [JsonConverter](https://learn.microsoft.com/en-us/dotnet/standard/serialization/system-text-json/converters-how-to?pivots=dotnet-6-0#registration-sample---jsonconverter-on-a-type) Annotations Creation of a dedicated `JsonConverter` helper into the `Agents.OpenAI` project to handle the serialization and deserialization of those types. Annotate those Content types with `[JsonConverter(typeof(KernelContentConverter))]` attribute to indicate the `JsonConverter` to be used. ### Agents.OpenAI's JsonConverter Example ```csharp public class KernelContentConverter : JsonConverter { public override KernelContent Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options) { using (var jsonDoc = JsonDocument.ParseValue(ref reader)) { var root = jsonDoc.RootElement; var typeDiscriminator = root.GetProperty("TypeDiscriminator").GetString(); switch (typeDiscriminator) { case nameof(AnnotationContent): return JsonSerializer.Deserialize(root.GetRawText(), options); case nameof(FileReferenceContent): return JsonSerializer.Deserialize(root.GetRawText(), options); default: throw new NotSupportedException($"Type discriminator '{typeDiscriminator}' is not supported."); } } } public override void Write(Utf8JsonWriter writer, KernelContent value, JsonSerializerOptions options) { JsonSerializer.Serialize(writer, value, value.GetType(), options); } } [JsonConverter(typeof(KernelContentConverter))] public class FileReferenceContent : KernelContent { public string FileId { get; init; } = string.Empty; ctor() ctor(string fileId, ...) } [JsonConverter(typeof(KernelContentConverter))] public class AnnotationContent : KernelContent { public string? FileId { get; init; } public string? Quote { get; init; } public int StartIndex { get; init; } public int EndIndex { get; init; } public ctor() public ctor(...) } ``` ## Decision Outcome - `BinaryContent`: Accepted. - `ImageContent`: Breaking change accepted with benefits using the `BinaryContent` specialization. No backwards compatibility as the current `ImageContent` behavior is undesirable. - `AudioContent`: Experimental breaking changes using the `BinaryContent` specialization. - `FunctionCallContent`: Graduate as is. - `FunctionResultContent`: Experimental breaking change from property `Id` to `CallId` to avoid confusion regarding being a function call Id or a response id. - `FileReferenceContent` and `AnnotationContent`: No changes, continue as experimental. ================================================ FILE: docs/decisions/0047-azure-open-ai-connectors.md ================================================ --- # These are optional elements.

Previously, there was no official SDK for OpenAI, and our OpenAI Connector relied solely on the Azure SDK client for access. With the introduction of the official OpenAI SDK, we now have access to more up-to-date features provided by OpenAI, making it advantageous to use this SDK instead of the Azure SDK. Additionally, it has become clear that we need to separate the OpenAI connector into two distinct targets: one for OpenAI and another for Azure OpenAI. This separation will enhance code clarity and facilitate a better understanding of the usage of each target. ## Decision Drivers - Update our connectors to use latest versions of OpenAI and Azure SDKs. - Minimize or eliminate any breaking changes for developers currently using the existing OpenAI connector. - Changes made should be be future proof. ## Versioning Although current `Azure.AI.OpenAI` and `OpenAI` SDK packages have its major versions updated (2.0.0), that change does not represent a `SemanticKernel` major breaking change. Any of the alternative options provided below take in consideration the that the new updated version of `SemanticKernel.Connectors.OpenAI` and `SemanticKernel.Connectors.AzureOpenAI` will be a minor version bump `1.N+1.0` for all SemanticKernel packages. ### Meta Package Strategy Currently the `Microsoft.SemanticKernel` package is a meta package that includes both `SemanticKernel.Core` and `SemanticKernel.Connectors.OpenAI`, with the new changes a new project will be added to the meta package `SemanticKernel.Connectors.AzureOpenAI` that will include the new Azure OpenAI connector. ## Documentation (Upgrade Path) A documentation guidance and samples/examples will be created to guide on how to upgrade from the current OpenAI connector to the new when needed. ## OpenAI SDK limitations The new OpenAI SDK introduce some limitations that need to be considered and potentially can introduce breaking changes if not remediated by our internal implementation. - #### ⚠️ No support for multiple results (Choices) per request. **Remediation**: Internally make the multiple requests and combine them. **No remediation**: Breaking change removing `ResultsPerPrompt` from `OpenAIPromptExecutionSettings`. - #### ⚠️ Text Generation modality is not supported. **Remediation**: Internally provide a HttpClient to be used against `gpt-3.5-turbo-instruct` for text generation modality. Same way was done for `TextToImage`, `AudioToText` service modalities. **No remediation**: Breaking change removing any specific `TextGeneration` service implementations, this change don't impact `ChatCompletion` services that may still being used as `ITextGenerationService` implementations. ## Improvements This also represents an opportunity to improve the current OpenAI connector by introducing the `Configuration` pattern to allow more flexibility and control over the services and their configurations. ```csharp // Before builder.AddAzureOpenAIChatCompletion(deploymentName, endpoint, apiKey, httpClient); // After builder.AddAzureOpenAIChatCompletion(new { DeploymentName = modelId; Endpoint = endpoint; ApiKey = apiKey; }); ``` ```csharp // Before builder.AddAzureOpenAIChatCompletion(deploymentName, openAIClient, serviceId, modelId) // After builder.AddAzureOpenAIChatCompletion(new { DeploymentName = deploymentName; ServiceId = serviceId; ModelId = modelId; }, openAIClient); ``` ## Potential Dependency Conflicts Since `SemanticKernel.Connectors.AzureOpenAI` and `SemanticKernel.Connectors.OpenAI` share same `OpenAI 2.0.0` dependency, if the vestion of `OpenAI 2.0.0` differ on each, that may create conflict when both connector packages are used together in a project. If this happens: 1. Before updating our OpenAI connector package we will get in touch with `Azure.AI.OpenAI` team to align on the ETAs for their update. 2. Investigate if the most recent `OpenAI` package when used with a `Azure.AI.OpenAI` that initially was targeting an older version of `OpenAI` SDK will not cause any breaking changes or conflicts. 3. If There are conflicts and their ETA is small we may keep the `OpenAI` dependency on our `SemanticKernel.Connectors.OpenAI` similar to Azure's for a short period of time, otherwise we will evaluate moving forward with the `OpenAI` dependency version upgrade. ## Considered Options - Option 1 - Merge New and Legacy (Slow transition for independent connectors). - Option 2 - Independent Connectors from Start. - Option 3 - Keep OpenAI and Azure in the same connector (As is). ## Option 1 - Merge New and Legacy (Slow transition for independent connectors). This is the least breaking approach where we keep the current legacy OpenAI and AzureOpenAI APIs temporarily in the connector using last Azure SDK `Azure.AI.OpenAI 1.0.0-beta.17` and add new OpenAI specific APIs using the new `OpenAI 2.0.0-beta.*` SDK package. This approach also implies that a new connector will be created on a second moment for Azure OpenAI services specifically fully dependent on the latest `Azure.AI.OpenAI 2.0.0-beta.*` SDK package. In a later stage we will deprecate all the OpenAI and Azure legacy APIs in the `SemanticKernel.Connectors.OpenAI` namespace and remove Azure SDK `Azure.AI.OpenAI 1.0.0-beta.17` and those APIs in a future release, making the OpenAI Connector fully dedicated for OpenAI services only depending on with the `OpenAI 2.0.0-beta.*` dependency. ```mermaid graph TD A[SemanticKernel.Connectors.OpenAI] --> B[OpenAI 2.0.0-beta.*] A --> C[Azure.OpenAI 1.0.0-beta.17] D[SemanticKernel.Connectors.AzureOpenAI] --> E[Azure.AI.OpenAI 2.0.0-beta.*] ``` The new `Options` pattern we be used as an improvement as well as a measure to avoid breaking changes with the legacy APIs. Following this change the `SemanticKernel.Connectors.OpenAI` and a new `SemanticKernel.Connectors.AzureOpenAI` connector will be created for Azure specific services, using the new Azure SDK `Azure.AI.OpenAI 2.0.0-beta.*` with all new APIs using the options approach. ### Phases of the transition - **Phase 1**: Add new OpenAI SDK APIs to the current OpenAI connector and keep the Azure OpenAI APIs using the last Azure SDK. - **Phase 2**: - Create a new connector for Azure OpenAI services using the new Azure SDK - Deprecate all Azure OpenAI APIs in the `OpenAI` connector pointing to new `AzureOpenAI` connector - Remove Azure SDK dependency from the OpenAI connector. - Add `AzureOpenAI` connector to the `Microsoft.SemanticKernel` meta package. - **Phase 3**: Deprecate all legacy `OpenAI APIs` in the `OpenAI` connector pointing to new `Options` APIs. - **Phase 4**: Remove all legacy APIs from the OpenAI connector. ### Impact Pros: - Minimal breaking changes for developers using the current OpenAI connector. - Clear separation of concerns between OpenAI and Azure OpenAI connectors. Cons: - Since `SemanticKernel.Connectors.AzureOpenAI` and `SemanticKernel.Connectors.OpenAI` share a same dependency of different versions, both packages cannot be used in the same project and a strategy will be needed when deploying both connectors. - Added dependency for both `Azure OpenAI 1.0-beta17` and `OpenAI 2.0-beta1`. ### Dependency Management Strategies 1. Use only one of the connectors in the same project, some modifications will be needed to accommodate `Concepts` and other projects that shares OpenAI and AzureOpenAI examples. 2. Hold AzureOpenAI connector implementation until we are ready to break (exclude) all Azure APIs in OpenAI connector. 3. Deploy a new project with a new namespace for `Azure.AI.OpenAI.Legacy 1.0.0-beta.17` and update our `SemanticKernel.Connectors.OpenAI` to use this new namespace to avoid version clashing on the `Azure.AI.OpenAI` namespace. ## Option 2 - Independent Connectors from Start. This option is focused on creating fully independent connectors for OpenAI and Azure OpenAI services since the start with all breaking changes needed to achieve that. ```mermaid graph TD D[SemanticKernel.Connectors.AzureOpenAI] --> E[Azure.AI.OpenAI 2.0.0-beta.*] E --> B[OpenAI 2.0.0-beta.*] A[SemanticKernel.Connectors.OpenAI] --> B[OpenAI 2.0.0-beta.*] ``` Impact: - All `Azure` related logic will be removed from `SemanticKernel.Connectors.OpenAI` to avoid any clashes with same names introduced in the new `SemanticKernel.Connectors.AzureOpenAI` as well as sending a congruent message to developers that the OpenAI connector is focused on OpenAI services only moving forward. ### Impact Pros: - Clear separation of concerns between OpenAI and Azure OpenAI connectors. - Small breaking changes for developers focused on OpenAI specific APIs. - Faster transition to the new OpenAI SDK and Azure OpenAI SDK. Cons: - Large breaking changes for developers using the current OpenAI connector for Azure. - [Potential Dependency Conflicts](#potential-dependency-conflicts) may arise if the `Azure.AI.OpenAI` team does not update their package. ## Option 3 - Keep OpenAI and Azure in the same connector (As is). This option is fully focused in the least impact possible, combining both Azure and OpenAI SDK dependencies in one single connector following the same approach as the current connector. Changes: 1. Update all current OpenAI specific services and client to use new OpenAI SDK 2. Update Azure specific services and client to use the latest Azure OpenAI SDK. 3. Optionally add `Options` pattern new APIs to the connector services and deprecate old ones. ### Impact Pros: - Minimal breaking changes for developers using the current OpenAI connector. - The breaking changes will be limited on how we tackle the points mentioned in the [OpenAI SDK limitations](#openai-sdk-limitations) above. - Will not have a dependency conflict between `Azure.AI.OpenAI` and `OpenAI` SDKs. Cons: - We will be limited on the OpenAI SDK version that is used by the latest `Azure.AI.OpenAI` package, which may not be the latest version available. - When using direct Azure or OpenAI specific services developers don't expect to see other provider specific services in their pool of options and dependencies. ## Decision Outcome ### Option 2 - Independent Connectors from Start. This option is the faster approach on transitioning to a potential 1.0 general availability of `OpenAI` SDK. This also option provides a clear separation of concerns between OpenAI and Azure OpenAI connectors from the start. Prevents any confusion sending a clear message on our intentions on splitting `OpenAI` and `AzureOpenAI` components away. #### OpenAI SDK limitations: - [Multiple results](#openai-sdk-limitations): **Do not remediate**. - [Text Generation modality is not supported](#openai-sdk-limitations): **Do not remediate**. ================================================ FILE: docs/decisions/0048-agent-chat-serialization.md ================================================ --- status: proposed contact: crickman date: 2024-06-24 deciders: bentho, matthewbolanos --- # `AgentChat` Serialization / Deserialization ## Context and Problem Statement Users of the _Agent Framework_ are unable to store and later retrieve conversation state when using an `AgentChat` to coordinate `Agent` interactions. This limits the ability for an agent conversation to single use as it must be maintained with memory of the process that initiated the conversation. Formalizing a mechanism that supports serialization and deserialization of any `AgentChat` class provides an avenue to capture and restore state across multiple sessions as well as compute boundaries. #### Goals - **Capture & Restore Primary Chat History**: The primary `AgentChat` history must be captured and restored for full fidelity. - **Capture & Restore Channel State**: In addition to the primary chat history, the state for each `AgentChannel` within the `AgentChat` must be captured and restored. - **Capture Agent Metadata**: Capturing the agent Identifier, Name, and Type upon serialization provides a guidance on how to restore the the `AgentChat` during deserialization. #### Non-Goals - **Manage agent definition:** An `Agent` definition shall not be captured as part of the conversation state. `Agent` instances will not be produced when deserializing the state of an `AgentChat` class. - **Manage secrets or api-keys:** Secrets / api-keys are required when producing an `Agent` instance. Managing this type of sensitive data is out-of-scope due to security considerations. ## Issues - Serialized `ChatHistory` must be equivalent across platforms / languages for interoperability ## Cases When restoring an `AgentChat`, the application must also re-create the `Agent` instances participating in the chat (outside of the control of the deserialization process). This creates the opportunity for the following cases: #### 1. **Equivalent:** All of the original agent types (channels) available in the restored chat. This shall result in a full-fidelity restoration of of the original chat. |Source Chat|Target Chat| |---|---| |`ChatCompletionAgent`|`ChatCompletionAgent`| |`OpenAIAssistantAgent`|`OpenAIAssistantAgent`| |`ChatCompletionAgent` & `OpenAIAssistantAgent`|`ChatCompletionAgent` & `OpenAIAssistantAgent`| #### 2. **Enhanced:** Additional original agent types (channels) available in the restored chat. This shall also result in a full-fidelity restoration of of the original chat. Any new agent type (channel) will synchronize to the chat once restored (identical to adding a new agent type to a chat that is progress). |Source Chat|Target Chat| |---|---| |`ChatCompletionAgent`|`ChatCompletionAgent` & `OpenAIAssistantAgent`| |`OpenAIAssistantAgent`|`ChatCompletionAgent` & `OpenAIAssistantAgent`| #### 3. **Reduced:** A subset of original agent types (channels) available in the restored chat. This shall also result in a full-fidelity restoration of of the original chat to the available channels. Introduction of a missing agent type (channel) post restoration will synchronize the channel to the current chat (identical to adding a new agent type to a chat that is progress). |Source Chat|Target Chat| |---|---| |`ChatCompletionAgent` & `OpenAIAssistantAgent`|`ChatCompletionAgent`| |`ChatCompletionAgent` & `OpenAIAssistantAgent`|`OpenAIAssistantAgent`| #### 4. **Empty:** No agents available in the restored chat. This shall result in an immediate exception (fail-fast) in order to strongly indicate that the chat has not been restored. The chat may have agents added in order to attempt a successful restoration, or utilized on its own. That is, the `AgentChat` instance isn't invalidated. #### 5. **Invalid:** Chat has already developed history or channels state. This shall result in an immediate exception (fail-fast) in order to strongly indicate that the chat has not been restored. The chat may continue to be utilized as the `AgentChat` instance isn't invalidated. #### Notes: > Once restored, additional `Agent` instances may join the `AgentChat`, no different from any `AgentChat` instance. ## Analysis #### Relationships: The relationships between any `AgentChat`, the `Agent` instances participating in the conversation, and the associated `AgentChannel` conduits are illustrated in the following diagram:

While an `AgentChat` manages a primary `ChatHistory`, each `AgentChannel` manages how that history is adapted to the specific `Agent` modality. For instance, an `AgentChannel` for an `Agent` based on the Open AI Assistant API tracks the associated _thread-id_. Whereas a `ChatCompletionAgent` manages an adapted `ChatHistory` instance of its own. This implies that logically the `AgentChat` state must retain the primary `ChatHistory` in addition to the appropriate state for each `AgentChannel`: #### Logical State: These relationships translate into the following logical state definition:

#### Serialized State: ```javascript { // Serialized ChatHistory "history": [ { "role": "user", "items": [ /* ... */ ] }, { "role": "assistant", "name": "John", "items": [ /* ... */ ] }, // ... ], // Serialized Participants "participants": [ { "id": "01b6a120-7fef-45e2-aafb-81cf4a90d931", "name": "John", "type": "ChatCompletionAgent" }, // ... ], // Serialized AgentChannel state "channels": [ { "channelkey": "Vdx37EnWT9BS+kkCkEgFCg9uHvHNw1+hXMA4sgNMKs4=", "channelstate": "...", // Serialized state for an AgentChannel }, // ... ] } ``` ## Options #### 1. JSON Serializer: A dominant serialization pattern is to use the dotnet `JsonSerializer`. This is the approach relied upon by the _Semantic Kernel_ content types. **Serialize Example:** (_dotnet_) ```c# // Create the agents ChatCompletionAgent agent1 = ...; OpenAIAssistantAgent agent2 = ...; // Create the agent-chat AgentGroupChat chat = new(agent1, agent2); // Serialize the chat object to JSON string chatState = JsonSerializer.Serialize(chat); ``` (_python_) ```python # Create the agents agent1 = ChatCompletionAgent(...) agent2 = OpenAIAssistantAgent(...) # Create the agent-chat chat = AgentGroupChat(agent1, agent2) # Serialize the chat to JSON chat_state = chat.model_dump() ``` **Deserialize Example:** (_dotnet_) ```c# // Deserialize JSON AgentGroupChat chat = JsonSerializer.Deserialize(chatState); ``` (_python_) ```python # Deserialize JSON def agent_group_chat_decoder(obj) -> AgentGroupChat: pass chat = json.loads(chat_state, object_hook=agent_group_chat_decoder) ``` **Pro:** - Doesn't require knowledge of a serialization pattern specific to the _Agent Framework_. **Con:** - Both `AgentChat` nor `AgentChannel` are designed as a service classes, not _data transfer objects_ (DTO's). Implies disruptive refactoring. (Think: complete re-write) - Requires caller to address complexity to support serialization of unknown `AgentChannel` and `AgentChat` subclasses. - Limits ability to post process when restoring chat (e.g. channel synchronization). - Absence of `Agent` instances in deserialization interferes with ability to restore any `AgentChannel`. #### 2. `AgentChat` Serializer: Introducing a serializer with specific knowledge of `AgentChat` contracts enables the ability to streamline serialization and deserialization. (_dotnet_) ```c# class AgentChatSerializer { // Captures chat state to the provided stream static async Task SerializeAsync(AgentChat chat, Stream stream) // Reads chat state from the provided stream and returns serializer static async Task DeserializeAsync(AgentChat chat, Stream stream) // Provides list of participants IReadOnlyList GetParticipants(); // Restores the chat state Task RestoreAsync(AgentChat chat); } ``` (_python_) ```python class AgentChatSerializer: # Captures chat state to the provided stream @staticmethod async def serialize(chat: AgentChat, stream); pass # Reads chat state from the provided stream and returns serializer @staticmethod async def deserialize(chat: AgentChat, stream) -> AgentChatSerializer: pass # Provides list of participants def get_participants(self) -> list[ChatParticipant]: pass # Restores the chat state async def restore(self, chat: AgentChat): pass ``` **Pro:** - Able to clearly define the chat-state, separate from the chat _service_ requirements. - Support any `AgentChat` and `AgentChannel` subclass. - Ability to support post processing when restoring chat (e.g. channel synchronization). - Allows any `AgentChat` to be properly initialized prior to deserialization. - Allows for inspection of `ChatParticipant` metadata. **Con:** - Require knowledge of a serialization pattern specific to the _Agent Framework_. **Serialize Example:** (_dotnet_) ```c# // Create agents ChatCompletionAgent agent1 = ...; OpenAIAssistantAgent agent2 = ...; // Create agent-chat AgentGroupChat chat = new(agent1, agent2); // Initiate conversation await chat.InvokeAsync(); // Initialize the serialization stream async using Stream stream = ...; // Capture agent-chat await AgentChatSerializer.SerializeAsync(chat, stream); ``` (_python_) ```python # Create agents agent1 = ChatCompletionAgent(...) agent2 = OpenAIAssistantAgent(...) # Create agent-chat chat = AgentGroupChat(agent1, agent2) # Initiate conversation await chat.invoke() # Initialize the serialization stream async with ... as stream: # Capture agent-chat await AgentChatSerializer.serialize(chat, stream) ``` **Deserialize Example:** (_dotnet_) ```c# // Create agents ChatCompletionAgent agent1 = ...; OpenAIAssistantAgent agent2 = ...; Dictionary agents = new() { { agent1.Id, agent1 }, { agent2.Id, agent2 }, } // Initialize the deserialization stream async using Stream stream = ...; AgentChatSerializer serializer = AgentChatSerializer.Deserialize(stream); // Create agent-chat AgentGroupChat chat = new(); // Restore agents foreach (ChatParticipant participant in serializer.GetParticipants()) { chat.AddAgent(agents[participant.Id]); } // Restore chat serializer.Deserialize(chat); // Continue chat await chat.InvokeAsync(); ``` (_python_) ```python # Create agents agent1 = ChatCompletionAgent(...) agent2 = OpenAIAssistantAgent(...) agents = { agent1.id: agent1, agent2.id: agent2, } # Initialize the serialization stream async with ... as stream: serializer = await AgentChatSerializer.serialize(stream) # Create agent-chat chat = AgentGroupChat(agent1, agent2) # Restore agents for participant in serializer.get_participants(): chat.add_agent(agents[participant.id]) # Restore agent-chat await serializer.deserialize(chat) # Continue chat await chat.invoke(); ``` #### 3. Encoded State This option is identical to the second option; however, each discrete state is base64 encoded to discourage modification / manipulation of the captured state. **Pro:** - Discourages ability to inspect and modify. **Con:** - Obscures ability to inspect. - Still able to decode to inspect and modify. **Serialized State:** ```javascript { "history": "VGhpcyBpcyB0aGUgcHJpbWFyeSBjaGF0IGhpc3Rvcnkg...", "participants": [ { "aId37EnWT9BS+kkCkEgFCg9uHvHNw1+hXMA4sgNMKs4...", // ... }, ], "channels": [ { "channelkey": "Vdx37EnWT9BS+kkCkEgFCg9uHvHNw1+hXMA4sgNMKs4=", "channelstate": "VGhpcyBpcyBhZ2VudCBjaGFubmVsIHN0YXRlIGV4YW1wbG..." }, // ... ] } ``` ## Outcome TBD ================================================ FILE: docs/decisions/0049-agents-assistantsV2.md ================================================ # Agent Framework - Assistant V2 Migration ## Context and Problem Statement Open AI has release the _Assistants V2_ API. This builds on top of the V1 _assistant_ concept, but also invalidates certain V1 features. In addition, the _dotnet_ API that supports _Assistant V2_ features is entirely divergent on the `Azure.AI.OpenAI.Assistants` SDK that is currently in use. ### Open Issues - **Streaming:** To be addressed as a discrete feature ## Design Migrating to Assistant V2 API is a breaking change to the existing package due to: - Underlying capability differences (e.g. `file-search` vs `retrieval`) - Underlying V2 SDK is version incompatible with V1 (`OpenAI` and `Azure.AI.OpenAI`) ### Agent Implementation The `OpenAIAssistant` agent is roughly equivalent to its V1 form save for: - Supports options for _assistant_, _thread_, and _run_ - Agent definition shifts to `Definition` property - Convenience methods for producing an OpenAI client Previously, the agent definition as exposed via direct properties such as: - `FileIds` - `Metadata` This has all been shifted and expanded upon via the `Definition` property which is of the same type (`OpenAIAssistantDefinition`) utilized to create and query an assistant.

The following table describes the purpose of diagramed methods on the `OpenAIAssistantAgent`. |Method Name|Description| ---|--- **Create**|Create a new assistant agent **ListDefinitions**|List existing assistant definitions **Retrieve**|Retrieve an existing assistant **CreateThread**|Create an assistant thread **DeleteThread**|Delete an assistant thread **AddChatMessage**|Add a message to an assistant thread **GetThreadMessages**|Retrieve all messages from an assistant thread **Delete**|Delete the assistant agent's definition (puts agent into a terminal state) **Invoke**|Invoke the assistant agent (no chat) **GetChannelKeys**|Inherited from `Agent` **CreateChannel**|Inherited from `Agent` ### Class Inventory This section provides an overview / inventory of all the public surface area described in this ADR. |Class Name|Description| ---|--- **OpenAIAssistantAgent**|An `Agent` based on the Open AI Assistant API **OpenAIAssistantChannel**|An 'AgentChannel' for `OpenAIAssistantAgent` (associated with a _thread-id_.) **OpenAIAssistantDefinition**|All of the metadata / definition for an Open AI Assistant. Unable to use the _Open AI API_ model due to implementation constraints (constructor not public). **OpenAIAssistantExecutionOptions**|Options that affect the _run_, but defined globally for the agent/assistant. **OpenAIAssistantInvocationOptions**|Options bound to a discrete run, used for direct (no chat) invocation. **OpenAIThreadCreationOptions**|Options for creating a thread that take precedence over assistant definition, when specified. **OpenAIServiceConfiguration**|Describes the service connection and used to create the `OpenAIClient` ### Run Processing The heart of supporting an _assistant_ agent is creating and processing a `Run`. A `Run` is effectively a discrete _assistant_ interaction on a `Thread` (or conversation). - https://platform.openai.com/docs/api-reference/runs - https://platform.openai.com/docs/api-reference/run-steps This `Run` processing is implemented as internal logic within the _OpenAI Agent Framework_ that is outlined here: Initiate processing using: - `agent` -> `OpenAIAssistantAgent` - `client` -> `AssistantClient` - `threadid` -> `string` - `options` -> `OpenAIAssistantInvocationOptions` (optional) Perform processing: - Verify `agent` not deleted - Define `RunCreationOptions` - Create the `run` (based on `threadid` and `agent.Id`) - Process the run: do - Poll `run` status until is not _queued_, _in-progress_, or _cancelling_ - Throw if `run` status is _expired_, _failed_, or _cancelled_ - Query `steps` for `run` - if `run` status is _requires-action_ - process function `steps` - post function results - foreach (`step` is completed) - if (`step` is tool-call) generate and yield tool content - else if (`step` is message) generate and yield message content while (`run` status is not completed) ### Vector Store Support _Vector Store_ support is required in order to enable usage of the `file-search` tool. In alignment with V2 streaming of the `FileClient`, the caller may also directly target `VectorStoreClient` from the _OpenAI SDK_. ### Definition / Options Classes Specific configuration/options classes are introduced to support the ability to define assistant behavior at each of the supported articulation points (i.e. _assistant_, _thread_, & _run_). |Class|Purpose| |---|---| |`OpenAIAssistantDefinition`|Definition of the assistant. Used when creating a new assistant, inspecting an assistant-agent instance, or querying assistant definitions.| |`OpenAIAssistantExecutionOptions`|Options that affect run execution, defined within assistant scope.| |`OpenAIAssistantInvocationOptions`|Run level options that take precedence over assistant definition, when specified.| |`OpenAIAssistantToolCallBehavior`|Informs tool-call behavior for the associated scope: assistant or run.| |`OpenAIThreadCreationOptions`|Thread scoped options that take precedence over assistant definition, when specified.| |`OpenAIServiceConfiguration`|Informs the which service to target, and how.| #### Assistant Definition The `OpenAIAssistantDefinition` was previously used only when enumerating a list of stored agents. It has been evolved to also be used as input for creating and agent and exposed as a discrete property on the `OpenAIAssistantAgent` instance. This includes optional `ExecutionOptions` which define default _run_ behavior. Since these execution options are not part of the remote assistant definition, they are persisted in the assistant metadata for when an existing agent is retrieved. `OpenAIAssistantToolCallBehavior` is included as part of the _execution options_ and modeled in alignment with the `ToolCallBehavior` associated with _AI Connectors_. > Note: Manual function calling isn't currently supported for `OpenAIAssistantAgent` or `AgentChat` and is planned to be addressed as an enhancement. When this supported is introduced, `OpenAIAssistantToolCallBehavior` will determine the function calling behavior (also in alignment with the `ToolCallBehavior` associated with _AI Connectors_). **Alternative (Future?)** A pending change has been authored that introduces `FunctionChoiceBehavior` as a property of the base / abstract `PromptExecutionSettings`. Once realized, it may make sense to evaluate integrating this pattern for `OpenAIAssistantAgent`. This may also imply in inheritance relationship of `PromptExecutionSettings` for both `OpenAIAssistantExecutionOptions` and `OpenAIAssistantInvocationOptions` (next section). **DECISION**: Do not support `tool_choice` until the `FunctionChoiceBehavior` is realized.

#### Assistant Invocation Options When invoking an `OpenAIAssistantAgent` directly (no-chat), definition that only apply to a discrete run may be specified. These definition are defined as `OpenAIAssistantInvocationOptions` and overtake precedence over any corresponding assistant or thread definition. > Note: These definition are also impacted by the `ToolCallBehavior` / `FunctionChoiceBehavior` quandary.

#### Thread Creation Options When invoking an `OpenAIAssistantAgent` directly (no-chat), a thread must be explicitly managed. When doing so, thread specific options may be specified. These options are defined as `OpenAIThreadCreationOptions` and take precedence over any corresponding assistant definition.

#### Service Configuration The `OpenAIServiceConfiguration` defines how to connect to a specific remote service, whether it be OpenAI, Azure, or proxy. This eliminates the need to define multiple overloads for each call site that results in a connection to the remote API service (i.e. create a _client)_. > Note: This was previously named `OpenAIAssistantConfiguration`, but is not necessarily assistant specific.

Each Memory connector implements a memory abstraction defined by Semantic Kernel and allows developers to easily integrate Vector databases into their applications. The current abstractions are experimental and the purpose of this ADR is to progress the design of the abstractions so that they can graduate to non experimental status. ### Problems with current design 1. The `IMemoryStore` interface has four responsibilities with different cardinalities. Some are schema aware and others schema agnostic. 2. The `IMemoryStore` interface only supports a fixed schema for data storage, retrieval and search, which limits its usability by customers with existing data sets. 2. The `IMemoryStore` implementations are opinionated around key encoding / decoding and collection name sanitization, which limits its usability by customers with existing data sets. Responsibilities: |Functional Area|Cardinality|Significance to Semantic Kernel| |-|-|-| |Collection/Index create|An implementation per store type and model|Valuable when building a store and adding data| |Collection/Index list names, exists and delete|An implementation per store type|Valuable when building a store and adding data| |Data Storage and Retrieval|An implementation per store type|Valuable when building a store and adding data| |Vector Search|An implementation per store type, model and search type|Valuable for many scenarios including RAG, finding contradictory facts based on user input, finding similar memories to merge, etc.| ### Memory Store Today ```cs interface IMemoryStore { // Collection / Index Management Task CreateCollectionAsync(string collectionName, CancellationToken cancellationToken = default); IAsyncEnumerable GetCollectionsAsync(CancellationToken cancellationToken = default); Task DoesCollectionExistAsync(string collectionName, CancellationToken cancellationToken = default); Task DeleteCollectionAsync(string collectionName, CancellationToken cancellationToken = default); // Data Storage and Retrieval Task UpsertAsync(string collectionName, MemoryRecord record, CancellationToken cancellationToken = default); IAsyncEnumerable UpsertBatchAsync(string collectionName, IEnumerable records, CancellationToken cancellationToken = default); Task GetAsync(string collectionName, string key, bool withEmbedding = false, CancellationToken cancellationToken = default); IAsyncEnumerable GetBatchAsync(string collectionName, IEnumerable keys, bool withVectors = false, CancellationToken cancellationToken = default); Task RemoveAsync(string collectionName, string key, CancellationToken cancellationToken = default); Task RemoveBatchAsync(string collectionName, IEnumerable keys, CancellationToken cancellationToken = default); // Vector Search IAsyncEnumerable<(MemoryRecord, double)> GetNearestMatchesAsync( string collectionName, ReadOnlyMemory embedding, int limit, double minRelevanceScore = 0.0, bool withVectors = false, CancellationToken cancellationToken = default); Task<(MemoryRecord, double)?> GetNearestMatchAsync( string collectionName, ReadOnlyMemory embedding, double minRelevanceScore = 0.0, bool withEmbedding = false, CancellationToken cancellationToken = default); } ``` ### Actions 1. The `IMemoryStore` should be split into different interfaces, so that schema aware and schema agnostic operations are separated. 2. The **Data Storage and Retrieval** and **Vector Search** areas should allow typed access to data and support any schema that is currently available in the customer's data store. 3. The collection / index create functionality should allow developers to use a common definition that is part of the abstraction to create collections. 4. The collection / index list/exists/delete functionality should allow management of any collection regardless of schema. 5. Remove opinionated behaviors from connectors. The opinionated behavior limits the ability of these connectors to be used with pre-existing vector databases. As far as possible these behaviors should be moved into decorators or be injectable. Examples of opinionated behaviors: 1. The AzureAISearch connector encodes keys before storing and decodes them after retrieval since keys in Azure AI Search supports a limited set of characters. 2. The AzureAISearch connector sanitizes collection names before using them, since Azure AI Search supports a limited set of characters. 3. The Redis connector prepends the collection name on to the front of keys before storing records and also registers the collection name as a prefix for records to be indexed by the index. ### Non-functional requirements for new connectors 1. Ensure all connectors are throwing the same exceptions consistently with data about the request made provided in a consistent manner. 2. Add consistent telemetry for all connectors. 3. As far as possible integration tests should be runnable on build server. ### New Designs The separation between collection/index management and record management. ```mermaid --- title: SK Collection/Index and record management --- classDiagram note for IVectorRecordStore "Can manage records for any scenario" note for IVectorCollectionCreate "Can create collections and\nindexes" note for IVectorCollectionNonSchema "Can retrieve/delete any collections and\nindexes" namespace SKAbstractions{ class IVectorCollectionCreate{ <> +CreateCollection } class IVectorCollectionNonSchema{ <> +GetCollectionNames +CollectionExists +DeleteCollection } class IVectorRecordStore~TModel~{ <> +Upsert(TModel record) string +UpsertBatch(TModel record) string +Get(string key) TModel +GetBatch(string[] keys) TModel[] +Delete(string key) +DeleteBatch(string[] keys) } } namespace AzureAIMemory{ class AzureAISearchVectorCollectionCreate{ } class AzureAISearchVectorCollectionNonSchema{ } class AzureAISearchVectorRecordStore{ } } namespace RedisMemory{ class RedisVectorCollectionCreate{ } class RedisVectorCollectionNonSchema{ } class RedisVectorRecordStore{ } } IVectorCollectionCreate <|-- AzureAISearchVectorCollectionCreate IVectorCollectionNonSchema <|-- AzureAISearchVectorCollectionNonSchema IVectorRecordStore <|-- AzureAISearchVectorRecordStore IVectorCollectionCreate <|-- RedisVectorCollectionCreate IVectorCollectionNonSchema <|-- RedisVectorCollectionNonSchema IVectorRecordStore <|-- RedisVectorRecordStore ``` How to use your own schema with core sk functionality. ```mermaid --- title: Chat History Break Glass --- classDiagram note for IVectorRecordStore "Can manage records\nfor any scenario" note for IVectorCollectionCreate "Can create collections\nan dindexes" note for IVectorCollectionNonSchema "Can retrieve/delete any\ncollections and indexes" note for CustomerHistoryVectorCollectionCreate "Creates history collections and indices\nusing Customer requirements" note for CustomerHistoryVectorRecordStore "Decorator class for IVectorRecordStore that maps\nbetween the customer model to our model" namespace SKAbstractions{ class IVectorCollectionCreate{ <> +CreateCollection } class IVectorCollectionNonSchema{ <> +GetCollectionNames +CollectionExists +DeleteCollection } class IVectorRecordStore~TModel~{ <> +Upsert(TModel record) string +Get(string key) TModel +Delete(string key) string } class ISemanticTextMemory{ <> +SaveInformationAsync() +SaveReferenceAsync() +GetAsync() +DeleteAsync() +SearchAsync() +GetCollectionsAsync() } } namespace CustomerProject{ class CustomerHistoryModel{ +string text +float[] vector +Dictionary~string, string~ properties } class CustomerHistoryVectorCollectionCreate{ +CreateCollection } class CustomerHistoryVectorRecordStore{ -IVectorRecordStore~CustomerHistoryModel~ _store +Upsert(ChatHistoryModel record) string +Get(string key) ChatHistoryModel +Delete(string key) string } } namespace SKCore{ class SemanticTextMemory{ -IVectorRecordStore~ChatHistoryModel~ _VectorRecordStore -IMemoryCollectionService _collectionsService -ITextEmbeddingGenerationService _embeddingGenerationService } class ChatHistoryPlugin{ -ISemanticTextMemory memory } class ChatHistoryModel{ +string message +float[] embedding +Dictionary~string, string~ metadata } } IVectorCollectionCreate <|-- CustomerHistoryVectorCollectionCreate IVectorRecordStore <|-- CustomerHistoryVectorRecordStore IVectorRecordStore <..

I'm therefore proposing that we allow mappers to be injectable for each `VectorStoreCollection` instance. The interfaces for these would vary depending on the storage models used by each vector store and any unique capabilities that each vector store may have, e.g. qdrant can operate in `single` or `multiple named vector` modes, which means the mapper needs to know whether to set a single vector or fill a vector map. In addition to this, we should build first party mappers for each of the vector stores, which will cater for built in, generic models or use metadata to perform the mapping. ### Support for different storage schemas The different stores vary in many ways around how data is organized. - Some just store a record with fields on it, where fields can be a key or a data field or a vector and their type is determined at collection creation time. - Others separate fields by type when interacting with the api, e.g. you have to specify a key explicitly, put metadata into a metadata dictionary and put vectors into a vector array. I'm proposing that we allow two ways in which to provide the information required to map data between the consumer data model and storage data model. First is a set of configuration objects that capture the types of each field. Second would be a set of attributes that can be used to decorate the model itself and can be converted to the configuration objects, allowing a single execution path. Additional configuration properties can easily be added for each type of field as required, e.g. IsFilterable or IsFullTextSearchable, allowing us to also create an index from the provided configuration. I'm also proposing that even though similar attributes already exist in other systems, e.g. System.ComponentModel.DataAnnotations.KeyAttribute, we create our own. We will likely require additional properties on all these attributes that are not currently supported on the existing attributes, e.g. whether a field is or should be filterable. Requiring users to switch to new attributes later will be disruptive. Here is what the attributes would look like, plus a sample use case. ```cs sealed class VectorStoreRecordKeyAttribute : Attribute { } sealed class VectorStoreRecordDataAttribute : Attribute { public bool HasEmbedding { get; set; } public string EmbeddingPropertyName { get; set; } } sealed class VectorStoreRecordVectorAttribute : Attribute { } public record HotelInfo( [property: VectorStoreRecordKey, JsonPropertyName("hotel-id")] string HotelId, [property: VectorStoreRecordData, JsonPropertyName("hotel-name")] string HotelName, [property: VectorStoreRecordData(HasEmbedding = true, EmbeddingPropertyName = "DescriptionEmbeddings"), JsonPropertyName("description")] string Description, [property: VectorStoreRecordVector, JsonPropertyName("description-embeddings")] ReadOnlyMemory? DescriptionEmbeddings); ``` Here is what the configuration objects would look like. ```cs abstract class VectorStoreRecordProperty(string propertyName); sealed class VectorStoreRecordKeyProperty(string propertyName): Field(propertyName) { } sealed class VectorStoreRecordDataProperty(string propertyName): Field(propertyName) { bool HasEmbedding; string EmbeddingPropertyName; } sealed class VectorStoreRecordVectorProperty(string propertyName): Field(propertyName) { } sealed class VectorStoreRecordDefinition { IReadOnlyList Properties; } ``` ### Notable method signature changes from existing interface All methods currently existing on IMemoryStore will be ported to new interfaces, but in places I am proposing that we make changes to improve consistency and scalability. 1. `RemoveAsync` and `RemoveBatchAsync` renamed to `DeleteAsync` and `DeleteBatchAsync`, since record are actually deleted, and this also matches the verb used for collections. 2. `GetCollectionsAsync` renamed to `GetCollectionNamesAsync`, since we are only retrieving names and no other information about collections. 3. `DoesCollectionExistAsync` renamed to `CollectionExistsAsync` since this is shorter and is more commonly used in other apis. ### Comparison with other AI frameworks |Criteria|Current SK Implementation|Proposed SK Implementation|Spring AI|LlamaIndex|Langchain| |-|-|-|-|-|-| |Support for Custom Schemas|N|Y|N|N|N| |Naming of store|MemoryStore|VectorStore, VectorStoreCollection|VectorStore|VectorStore|VectorStore| |MultiVector support|N|Y|N|N|N| |Support Multiple Collections via SDK params|Y|Y|N (via app config)|Y|Y| ## Decision Drivers From GitHub Issue: - API surface must be easy to use and intuitive - Alignment with other patterns in the SK - - Design must allow Memory Plugins to be easily instantiated with any connector - Design must support all Kernel content types - Design must allow for database specific configuration - All NFR's to be production ready are implemented (see Roadmap for more detail) - Basic CRUD operations must be supported so that connectors can be used in a polymorphic manner - Official Database Clients must be used where available - Dynamic database schema must be supported - Dependency injection must be supported - Azure-ML YAML format must be supported - Breaking glass scenarios must be supported ## Considered Questions 1. Combined collection and record management vs separated. 2. Collection name and key value normalization in decorator or main class. 3. Collection name as method param or constructor param. 4. How to normalize ids across different vector stores where different types are supported. 5. Store Interface/Class Naming ### Question 1: Combined collection and record management vs separated. #### Option 1 - Combined collection and record management ```cs interface IVectorRecordStore { Task CreateCollectionAsync(CollectionCreateConfig collectionConfig, CancellationToken cancellationToken = default); IAsyncEnumerable ListCollectionNamesAsync(CancellationToken cancellationToken = default); Task CollectionExistsAsync(string name, CancellationToken cancellationToken = default); Task DeleteCollectionAsync(string name, CancellationToken cancellationToken = default); Task UpsertAsync(TRecord data, CancellationToken cancellationToken = default); IAsyncEnumerable UpsertBatchAsync(IEnumerable dataSet, CancellationToken cancellationToken = default); Task GetAsync(string key, bool withEmbedding = false, CancellationToken cancellationToken = default); IAsyncEnumerable GetBatchAsync(IEnumerable keys, bool withVectors = false, CancellationToken cancellationToken = default); Task DeleteAsync(string key, CancellationToken cancellationToken = default); Task DeleteBatchAsync(IEnumerable keys, CancellationToken cancellationToken = default); } class AzureAISearchVectorRecordStore( Azure.Search.Documents.Indexes.SearchIndexClient client, Schema schema): IVectorRecordStore; class WeaviateVectorRecordStore( WeaviateClient client, Schema schema): IVectorRecordStore; class RedisVectorRecordStore( StackExchange.Redis.IDatabase database, Schema schema): IVectorRecordStore; ``` #### Option 2 - Separated collection and record management with opinionated create implementations ```cs interface IVectorCollectionStore { virtual Task CreateChatHistoryCollectionAsync(string name, CancellationToken cancellationToken = default); virtual Task CreateSemanticCacheCollectionAsync(string name, CancellationToken cancellationToken = default); IAsyncEnumerable ListCollectionNamesAsync(CancellationToken cancellationToken = default); Task CollectionExistsAsync(string name, CancellationToken cancellationToken = default); Task DeleteCollectionAsync(string name, CancellationToken cancellationToken = default); } class AzureAISearchVectorCollectionStore: IVectorCollectionStore; class RedisVectorCollectionStore: IVectorCollectionStore; class WeaviateVectorCollectionStore: IVectorCollectionStore; // Customers can inherit from our implementations and replace just the creation scenarios to match their schemas. class CustomerCollectionStore: AzureAISearchVectorCollectionStore, IVectorCollectionStore; // We can also create implementations that create indices based on an MLIndex specification. class MLIndexAzureAISearchVectorCollectionStore(MLIndex mlIndexSpec): AzureAISearchVectorCollectionStore, IVectorCollectionStore; interface IVectorRecordStore { Task GetAsync(string key, GetRecordOptions? options = default, CancellationToken cancellationToken = default); Task DeleteAsync(string key, DeleteRecordOptions? options = default, CancellationToken cancellationToken = default); Task UpsertAsync(TRecord record, UpsertRecordOptions? options = default, CancellationToken cancellationToken = default); } class AzureAISearchVectorRecordStore(): IVectorRecordStore; ``` #### Option 3 - Separated collection and record management with collection create separate from other operations. Vector store same as option 2 so not repeated for brevity. ```cs interface IVectorCollectionCreate { virtual Task CreateCollectionAsync(string name, CancellationToken cancellationToken = default); } // Implement a generic version of create that takes a configuration that should work for 80% of cases. class AzureAISearchConfiguredVectorCollectionCreate(CollectionCreateConfig collectionConfig): IVectorCollectionCreate; // Allow custom implementations of create for break glass scenarios for outside the 80% case. class AzureAISearchChatHistoryVectorCollectionCreate: IVectorCollectionCreate; class AzureAISearchSemanticCacheVectorCollectionCreate: IVectorCollectionCreate; // Customers can create their own creation scenarios to match their schemas, but can continue to use our get, does exist and delete class. class CustomerChatHistoryVectorCollectionCreate: IVectorCollectionCreate; interface IVectorCollectionNonSchema { IAsyncEnumerable ListCollectionNamesAsync(CancellationToken cancellationToken = default); Task CollectionExistsAsync(string name, CancellationToken cancellationToken = default); Task DeleteCollectionAsync(string name, CancellationToken cancellationToken = default); } class AzureAISearchVectorCollectionNonSchema: IVectorCollectionNonSchema; class RedisVectorCollectionNonSchema: IVectorCollectionNonSchema; class WeaviateVectorCollectionNonSchema: IVectorCollectionNonSchema; ``` #### Option 4 - Separated collection and record management with collection create separate from other operations, with collection management aggregation class on top. Variation on option 3. ```cs interface IVectorCollectionCreate { virtual Task CreateCollectionAsync(string name, CancellationToken cancellationToken = default); } interface IVectorCollectionNonSchema { IAsyncEnumerable ListCollectionNamesAsync(CancellationToken cancellationToken = default); Task CollectionExistsAsync(string name, CancellationToken cancellationToken = default); Task DeleteCollectionAsync(string name, CancellationToken cancellationToken = default); } // DB Specific NonSchema implementations class AzureAISearchVectorCollectionNonSchema: IVectorCollectionNonSchema; class RedisVectorCollectionNonSchema: IVectorCollectionNonSchema; // Combined Create + NonSchema Interface interface IVectorCollectionStore: IVectorCollectionCreate, IVectorCollectionNonSchema {} // Base abstract class that forwards non-create operations to provided implementation. abstract class VectorCollectionStore(IVectorCollectionNonSchema collectionNonSchema): IVectorCollectionStore { public abstract Task CreateCollectionAsync(string name, CancellationToken cancellationToken = default); public IAsyncEnumerable ListCollectionNamesAsync(CancellationToken cancellationToken = default) { return collectionNonSchema.ListCollectionNamesAsync(cancellationToken); } public Task CollectionExistsAsync(string name, CancellationToken cancellationToken = default) { return collectionNonSchema.CollectionExistsAsync(name, cancellationToken); } public Task DeleteCollectionAsync(string name, CancellationToken cancellationToken = default) { return collectionNonSchema.DeleteCollectionAsync(name, cancellationToken); } } // Collections store implementations, that inherit from base class, and just adds the different creation implementations. class AzureAISearchChatHistoryVectorCollectionStore(AzureAISearchVectorCollectionNonSchema nonSchema): VectorCollectionStore(nonSchema); class AzureAISearchSemanticCacheVectorCollectionStore(AzureAISearchVectorCollectionNonSchema nonSchema): VectorCollectionStore(nonSchema); class AzureAISearchMLIndexVectorCollectionStore(AzureAISearchVectorCollectionNonSchema nonSchema): VectorCollectionStore(nonSchema); // Customer collections store implementation, that uses the base Azure AI Search implementation for get, doesExist and delete, but adds its own creation. class ContosoProductsVectorCollectionStore(AzureAISearchVectorCollectionNonSchema nonSchema): VectorCollectionStore(nonSchema); ``` #### Option 5 - Separated collection and record management with collection create separate from other operations, with overall aggregation class on top. Same as option 3 / 4, plus: ```cs interface IVectorStore : IVectorCollectionStore, IVectorRecordStore { } // Create a static factory that produces one of these, so only the interface is public, not the class. internal class VectorStore(IVectorCollectionCreate create, IVectorCollectionNonSchema nonSchema, IVectorRecordStore records): IVectorStore { } ``` #### Option 6 - Collection store acts as factory for record store. `IVectorStore` acts as a factory for `IVectorStoreCollection`, and any schema agnostic multi-collection operations are kept on `IVectorStore`. ```cs public interface IVectorStore { IVectorStoreCollection GetCollection(string name, VectorStoreRecordDefinition? vectorStoreRecordDefinition = null); IAsyncEnumerable ListCollectionNamesAsync(CancellationToken cancellationToken = default)); } public interface IVectorStoreCollection { public string Name { get; } // Collection Operations Task CreateCollectionAsync(); Task CreateCollectionIfNotExistsAsync(); Task CollectionExistsAsync(); Task DeleteCollectionAsync(); // Data manipulation Task GetAsync(TKey key, GetRecordOptions? options = default, CancellationToken cancellationToken = default); IAsyncEnumerable GetBatchAsync(IEnumerable keys, GetRecordOptions? options = default, CancellationToken cancellationToken = default); Task DeleteAsync(TKey key, DeleteRecordOptions? options = default, CancellationToken cancellationToken = default); Task DeleteBatchAsync(IEnumerable keys, DeleteRecordOptions? options = default, CancellationToken cancellationToken = default); Task UpsertAsync(TRecord record, UpsertRecordOptions? options = default, CancellationToken cancellationToken = default); IAsyncEnumerable UpsertBatchAsync(IEnumerable records, UpsertRecordOptions? options = default, CancellationToken cancellationToken = default); } ``` #### Decision Outcome Option 1 is problematic on its own, since we have to allow consumers to create custom implementations of collection create for break glass scenarios. With a single interface like this, it will require them to implement many methods that they do not want to change. Options 4 & 5, gives us more flexibility while still preserving the ease of use of an aggregated interface as described in Option 1. Option 2 doesn't give us the flexibility we need for break glass scenarios, since it only allows certain types of collections to be created. It also means that each time a new collection type is required it introduces a breaking change, so it is not a viable option. Since collection create and configuration and the possible options vary considerable across different database types, we will need to support an easy to use break glass scenario for collection creation. While we would be able to develop a basic configurable create option, for complex create scenarios users will need to implement their own. We will also need to support multiple create implementations out of the box, e.g. a configuration based option using our own configuration, create implementations that re-create the current model for backward compatibility, create implementations that use other configuration as input, e.g. Azure-ML YAML. Therefore separating create, which may have many implementations, from exists, list and delete, which requires only a single implementation per database type is useful. Option 3 provides us this separation, but Option 4 + 5 builds on top of this, and allows us to combine different implementations together for simpler consumption. Chosen option: 6 - Easy to use, and similar to many SDk implementations. - Can pass a single object around for both collection and record access. ### Question 2: Collection name and key value normalization in store, decorator or via injection. #### Option 1 - Normalization in main record store - Pros: Simple - Cons: The normalization needs to vary separately from the record store, so this will not work ```cs public class AzureAISearchVectorStoreCollection : IVectorStoreCollection { ... // On input. var normalizedCollectionName = this.NormalizeCollectionName(collectionName); var encodedId = AzureAISearchMemoryRecord.EncodeId(key); ... // On output. DecodeId(this.Id) ... } ``` #### Option 2 - Normalization in decorator - Pros: Allows normalization to vary separately from the record store. - Pros: No code executed when no normalization required. - Pros: Easy to package matching encoders/decoders together. - Pros: Easier to obsolete encoding/normalization as a concept. - Cons: Not a major con, but need to implement the full VectorStoreCollection interface, instead of e.g. just providing the two translation functions, if we go with option 3. - Cons: Hard to have a generic implementation that can work with any model, without either changing the data in the provided object on upsert or doing cloning in an expensive way. ```cs new KeyNormalizingAISearchVectorStoreCollection( "keyField", new AzureAISearchVectorStoreCollection(...)); ``` #### Option 3 - Normalization via optional function parameters to record store constructor - Pros: Allows normalization to vary separately from the record store. - Pros: No need to implement the full VectorStoreCollection interface. - Pros: Can modify values on serialization without changing the incoming record, if supported by DB SDK. - Cons: Harder to package matching encoders/decoders together. ```cs public class AzureAISearchVectorStoreCollection(StoreOptions options); public class StoreOptions { public Func? EncodeKey { get; init; } public Func? DecodeKey { get; init; } public Func? SanitizeCollectionName { get; init; } } ``` #### Option 4 - Normalization via custom mapper If developer wants to change any values they can do so by creating a custom mapper. - Cons: Developer needs to implement a mapper if they want to do normalization. - Cons: Developer cannot change collection name as part of the mapping. - Pros: No new extension points required to support normalization. - Pros: Developer can change any field in the record. #### Decision Outcome Chosen option 3, since it is similar to how we are doing mapper injection and would also work well in python. Option 1 won't work because if e.g. the data was written using another tool, it may be unlikely that it was encoded using the same mechanism as supported here and therefore this functionality may not be appropriate. The developer should have the ability to not use this functionality or provide their own encoding / decoding behavior. ### Question 3: Collection name as method param or via constructor or either #### Option 1 - Collection name as method param ```cs public class MyVectorStoreCollection() { public async Task GetAsync(string collectionName, string key, GetRecordOptions? options = default, CancellationToken cancellationToken = default); } ``` #### Option 2 - Collection name via constructor ```cs public class MyVectorStoreCollection(string defaultCollectionName) { public async Task GetAsync(string key, GetRecordOptions? options = default, CancellationToken cancellationToken = default); } ``` #### Option 3 - Collection name via either ```cs public class MyVectorStoreCollection(string defaultCollectionName) { public async Task GetAsync(string key, GetRecordOptions? options = default, CancellationToken cancellationToken = default); } public class GetRecordOptions { public string CollectionName { get; init; }; } ``` #### Decision Outcome Chosen option 2. None of the other options work with the decision outcome of Question 1, since that design requires the `VectorStoreCollection` to be tied to a single collection instance. ### Question 4: How to normalize ids across different vector stores where different types are supported. #### Option 1 - Take a string and convert to a type that was specified on the constructor ```cs public async Task GetAsync(string key, GetRecordOptions? options = default, CancellationToken cancellationToken = default) { var convertedKey = this.keyType switch { KeyType.Int => int.parse(key), KeyType.GUID => Guid.parse(key) } ... } ``` - No additional overloads are required over time so no breaking changes. - Most data types can easily be represented in string form and converted to/from it. #### Option 2 - Take an object and cast to a type that was specified on the constructor. ```cs public async Task GetAsync(object key, GetRecordOptions? options = default, CancellationToken cancellationToken = default) { var convertedKey = this.keyType switch { KeyType.Int => key as int, KeyType.GUID => key as Guid } if (convertedKey is null) { throw new InvalidOperationException($"The provided key must be of type {this.keyType}") } ... } ``` - No additional overloads are required over time so no breaking changes. - Any data types can be represented as object. #### Option 3 - Multiple overloads where we convert where possible, throw when not possible. ```cs public async Task GetAsync(string key, GetRecordOptions? options = default, CancellationToken cancellationToken = default) { var convertedKey = this.keyType switch { KeyType.Int => int.Parse(key), KeyType.String => key, KeyType.GUID => Guid.Parse(key) } } public async Task GetAsync(int key, GetRecordOptions? options = default, CancellationToken cancellationToken = default) { var convertedKey = this.keyType switch { KeyType.Int => key, KeyType.String => key.ToString(), KeyType.GUID => throw new InvalidOperationException($"The provided key must be convertible to a GUID.") } } public async Task GetAsync(GUID key, GetRecordOptions? options = default, CancellationToken cancellationToken = default) { var convertedKey = this.keyType switch { KeyType.Int => throw new InvalidOperationException($"The provided key must be convertible to an int.") KeyType.String => key.ToString(), KeyType.GUID => key } } ``` - Additional overloads are required over time if new key types are found on new connectors, causing breaking changes. - You can still call a method that causes a runtime error, when the type isn't supported. #### Option 4 - Add key type as generic to interface ```cs interface IVectorRecordStore { Task GetAsync(TKey key, GetRecordOptions? options = default, CancellationToken cancellationToken = default); } class AzureAISearchVectorRecordStore: IVectorRecordStore { public AzureAISearchVectorRecordStore() { // Check if TKey matches the type of the field marked as a key on TRecord and throw if they don't match. // Also check if keytype is one of the allowed types for Azure AI Search and throw if it isn't. } } ``` - No runtime issues after construction. - More cumbersome interface. #### Decision Outcome Chosen option 4, since it is forwards compatible with any complex key types we may need to support but still allows each implementation to hardcode allowed key types if the vector db only supports certain key types. ### Question 5: Store Interface/Class Naming. #### Option 1 - VectorDB ```cs interface IVectorDBRecordService {} interface IVectorDBCollectionUpdateService {} interface IVectorDBCollectionCreateService {} ``` #### Option 2 - Memory ```cs interface IMemoryRecordService {} interface IMemoryCollectionUpdateService {} interface IMemoryCollectionCreateService {} ``` ### Option 3 - VectorStore ```cs interface IVectorRecordStore {} interface IVectorCollectionNonSchema {} interface IVectorCollectionCreate {} interface IVectorCollectionStore {}: IVectorCollectionCreate, IVectorCollectionNonSchema interface IVectorStore {}: IVectorCollectionStore, IVectorRecordStore ``` ### Option 4 - VectorStore + VectorStoreCollection ```cs interface IVectorStore { IVectorStoreCollection GetCollection() } interface IVectorStoreCollection { Get() Delete() Upsert() } ``` #### Decision Outcome Chosen option 4. The word memory is broad enough to encompass any data, so using it seems arbitrary. All competitors are using the term vector store, so using something similar is good for recognition. Option 4 also matches our design as chosen in question 1. ## Usage Examples ### DI Framework: .net 8 Keyed Services ```cs class CacheEntryModel(string prompt, string result, ReadOnlyMemory promptEmbedding); class SemanticTextMemory(IVectorStore configuredVectorStore, VectorStoreRecordDefinition? vectorStoreRecordDefinition): ISemanticTextMemory { public async Task SaveInformation(string collectionName, TDataType record) { var collection = vectorStore.GetCollection(collectionName, vectorStoreRecordDefinition); if (!await collection.CollectionExists()) { await collection.CreateCollection(); } await collection.UpsertAsync(record); } } class CacheSetFunctionFilter(ISemanticTextMemory memory); // Saves results to cache. class CacheGetPromptFilter(ISemanticTextMemory memory); // Check cache for entries. var builder = Kernel.CreateBuilder(); builder // Existing registration: .AddAzureOpenAITextEmbeddingGeneration(textEmbeddingDeploymentName, azureAIEndpoint, apiKey, serviceId: "AzureOpenAI:text-embedding-ada-002") // Register an IVectorStore implementation under the given key. .AddAzureAISearch("Cache", azureAISearchEndpoint, apiKey, new Options() { withEmbeddingGeneration = true }); // Add Semantic Cache Memory for the cache entry model. builder.Services.AddTransient(sp => { return new SemanticTextMemory( sp.GetKeyedService("Cache"), cacheRecordDefinition); }); // Add filter to retrieve items from cache and one to add items to cache. // Since these filters depend on ISemanticTextMemory and that is already registered, it should get matched automatically. builder.Services.AddTransient(); builder.Services.AddTransient(); ``` ## Roadmap ### Record Management 1. Release VectorStoreCollection public interface and implementations for Azure AI Search, Qdrant and Redis. 2. Add support for registering record stores with SK container to allow automatic dependency injection. 3. Add VectorStoreCollection implementations for remaining stores. ### Collection Management 4. Release Collection Management public interface and implementations for Azure AI Search, Qdrant and Redis. 5. Add support for registering collection management with SK container to allow automatic dependency injection. 6. Add Collection Management implementations for remaining stores. ### Collection Creation 7. Release Collection Creation public interface. 8. Create cross db collection creation config that supports common functionality, and per database implementation that supports this configuration. 9. Add support for registering collection creation with SK container to allow automatic dependency injection. ### First Party Memory Features and well known model support 10. Add model and mappers for legacy SK MemoryStore interface, so that consumers using this has an upgrade path to the new memory storage stack. 11. Add model and mappers for popular loader systems, like Kernel Memory or LlamaIndex. 11. Explore adding first party implementations for common scenarios, e.g. semantic caching. Specifics TBD. ### Cross Cutting Requirements Need the following for all features: - Unit tests - Integration tests - Logging / Telemetry - Common Exception Handling - Samples, including: - Usage scenario for collection and record management using custom model and configured collection creation. - A simple consumption example like semantic caching, specifics TBD. - Adding your own collection creation implementation. - Adding your own custom model mapper. - Documentation, including: - How to create models and annotate/describe them to use with the storage system. - How to define configuration for creating collections using common create implementation. - How to use record and collection management apis. - How to implement your own collection create implementation for break glass scenario. - How to implement your own mapper. - How to upgrade from the current storage system to the new one. ================================================ FILE: docs/decisions/0051-dotnet-azure-model-as-a-service.md ================================================ --- # These are optional elements. Feel free to remove any of them. status: proposed contact: rogerbarreto date: 2024-08-07 deciders: rogerbarreto, markwallace-microsoft consulted: taochen --- # Support Connector for .Net Azure Model-as-a-Service (Azure AI Studio) ## Context and Problem Statement There has been a demand from customers to use and support natively models deployed in [Azure AI Studio - Serverless APIs](https://learn.microsoft.com/en-us/azure/ai-studio/how-to/model-catalog-overview#model-deployment-managed-compute-and-serverless-api-pay-as-you-go), This mode of consumption operates on a pay-as-you-go basis, typically using tokens for billing purposes. Clients can access the service via the [Azure AI Model Inference API](https://learn.microsoft.com/en-us/azure/ai-studio/reference/reference-model-inference-api?tabs=azure-studio) or client SDKs. At present, there is no official support for [Azure AI Studio](https://learn.microsoft.com/en-us/azure/ai-studio/what-is-ai-studio). The purpose of this ADR is to examine the constraints of the service and explore potential solutions to enable support for the service via the development of a new AI connector. ## Azure Inference Client library for .NET The Azure team has a new client library, namely [Azure.AI.Inference](https://github.com/Azure/azure-sdk-for-net/blob/Azure.AI.Inference_1.0.0-beta.1/sdk/ai/Azure.AI.Inference/README.md) in .Net, for effectively interacting with the service. While the service API is OpenAI-compatible, it is not permissible to use the OpenAI and the Azure OpenAI client libraries for interacting with the service as they are not independent with respect to both the models and their providers. This is because Azure AI Studio features a diverse range of open-source models, other than OpenAI models. ### Limitations Currently is known that the first version of the client SDK will only support: `Chat Completion` and `Text Embedding Generation` and `Image Embedding Generation` with `TextToImage Generation` planned. There are no current plans to support `Text Generation` modality. ## AI Connector ### Namespace options - `Microsoft.SemanticKernel.Connectors.AzureAI` - `Microsoft.SemanticKernel.Connectors.AzureAIInference` - `Microsoft.SemanticKernel.Connectors.AzureAIModelInference` Decision: `Microsoft.SemanticKernel.Connectors.AzureAIInference` ### Support for model-specific parameters Models can possess supplementary parameters that are not part of the default API. The service API and the client SDK enable the provision of model-specific parameters. Users can provide model-specific settings via a dedicated argument along with other settings, such as `temperature` and `top_p`, among others. Azure AI Inference specialized `PromptExecutionSettings`, will support those customizable parameters. ### Feature Branch The development of the Azure AI Inference connector will be done in a feature branch named `feature-connectors-azureaiinference`. ================================================ FILE: docs/decisions/0051-entity-framework-as-connector.md ================================================ --- # These are optional elements. Feel free to remove any of them. status: proposed contact: dmytrostruk date: 2024-08-20 deciders: sergeymenshykh, markwallace, rbarreto, westey-m --- # Entity Framework as Vector Store Connector ## Context and Problem Statement This ADR contains investigation results about adding Entity Framework as Vector Store connector to the Semantic Kernel codebase. Entity Framework is a modern object-relation mapper that allows to build a clean, portable, and high-level data access layer with .NET (C#) across a variety of databases, including SQL Database (on-premises and Azure), SQLite, MySQL, PostgreSQL, Azure Cosmos DB and more. It supports LINQ queries, change tracking, updates and schema migrations. One of the huge benefits of Entity Framework for Semantic Kernel is the support of multiple databases. In theory, one Entity Framework connector can work as a hub to multiple databases at the same time, which should simplify the development and maintenance of integration with these databases. However, there are some limitations, which won't allow Entity Framework to fit in updated Vector Store design. ### Collection Creation In new Vector Store design, interface `IVectorStoreRecordCollection` contains methods to manipulate with database collections: - `CollectionExistsAsync` - `CreateCollectionAsync` - `CreateCollectionIfNotExistsAsync` - `DeleteCollectionAsync` In Entity Framework, collection (also known as schema/table) creation using programmatic approach is not recommended in production scenarios. The recommended approach is to use Migrations (in case of code-first approach), or to use Reverse Engineering (also known as scaffolding/database-first approach). Programmatic schema creation is recommended only for testing/local scenarios. Also, collection creation process differs for different databases. For example, MongoDB EF Core provider doesn't support schema migrations or database-first/model-first approaches. Instead, the collection is created automatically when a document is inserted for the first time, if collection doesn't already exist. This brings the complexity around methods such as `CreateCollectionAsync` from `IVectorStoreRecordCollection` interface, since there is no abstraction around collection management in EF that will work for most databases. For such cases, the recommended approach is to rely on automatic creation or handle collection creation individually for each database. As an example, in MongoDB it's recommended to use MongoDB C# Driver directly.

In such case, it will be possible to support only standard type for keys such as `string`, and then the conversion should be performed to satisfy key restrictions for specific database. This removes the advantage of unified connector implementation, since key management should be handled for each database individually. Sources: - https://learn.microsoft.com/en-us/ef/core/modeling/keys?tabs=data-annotations ### Vector Management `ReadOnlyMemory` type, which is used in most SK connectors today to hold embeddings is not supported in Entity Framework out-of-the-box. When trying to use this type, the following error occurs: ``` The property '{Property Name}' could not be mapped because it is of type 'ReadOnlyMemory?', which is not a supported primitive type or a valid entity type. Either explicitly map this property, or ignore it using the '[NotMapped]' attribute or by using 'EntityTypeBuilder.Ignore' in 'OnModelCreating'. ``` However, it's possible to use `byte[]` type or create explicit mapping to support `ReadOnlyMemory`. It's already implemented in `pgvector` package, but it's not clear whether it will work with different databases.

Each database implements its own set of Entity Framework features, so in order to ensure that Entity Framework connector covers main use-cases with specific database, unit/integration tests should be added using each database separately. Sources: - https://github.com/mongodb/mongo-efcore-provider?tab=readme-ov-file#supported-features ### Compatibility It's not possible to use latest Entity Framework Core package and develop it for .NET Standard. Last version of EF Core which supports .NET Standard was version 5.0 (latest EF Core version is 8.0). Which means that Entity Framework connector can target .NET 8.0 only (which is different from other available SK connectors today, which target both net8.0 and netstandard2.0). Another way would be to use Entity Framework 6, which can target both net8.0 and netstandard2.0, but this version of Entity Framework is no longer being actively developed. Entity Framework Core offers new features that won't be implemented in EF6. Sources: - https://learn.microsoft.com/en-us/ef/core/miscellaneous/platforms - https://learn.microsoft.com/en-us/ef/efcore-and-ef6/ ### Existence of current SK connectors Taking into account that Semantic Kernel already has some integration with databases, which are also supported Entity Framework, there are multiple options how to proceed: - Support both Entity Framework and DB connector (e.g. `Microsoft.SemanticKernel.Connectors.EntityFramework` and `Microsoft.SemanticKernel.Connectors.MongoDB`) - in this case both connectors should produce exactly the same outcome, so additional work will be required (such as implementing the same set of unit/integration tests) to ensure this state. Also, any modifications to the logic should be applied in both connectors. - Support just one Entity Framework connector (e.g. `Microsoft.SemanticKernel.Connectors.EntityFramework`) - in this case, existing DB connector should be removed, which may be a breaking change to existing customers. An additional work will be required to ensure that Entity Framework covers exactly the same set of features as previous DB connector. - Support just one DB connector (e.g. `Microsoft.SemanticKernel.Connectors.MongoDB`) - in this case, if such connector already exists - no additional work is required. If such connector doesn't exist and it's important to add it - additional work is required to implement that DB connector. Table with Entity Framework and Semantic Kernel database support (only for databases which support vector search): |Database Engine|Maintainer / Vendor|Supported in EF|Supported in SK|Updated to SK memory v2 design |-|-|-|-|-| |Azure Cosmos|Microsoft|Yes|Yes|Yes| |Azure SQL and SQL Server|Microsoft|Yes|Yes|No| |SQLite|Microsoft|Yes|Yes|No| |PostgreSQL|Npgsql Development Team|Yes|Yes|No| |MongoDB|MongoDB|Yes|Yes|No| |MySQL|Oracle|Yes|No|No| |Oracle DB|Oracle|Yes|No|No| |Google Cloud Spanner|Cloud Spanner Ecosystem|Yes|No|No| **Note**: One database engine can have multiple Entity Framework integrations, which can be maintained by different vendors (e.g. there are 2 MySQL EF NuGet packages - one is maintained by Oracle and another one is maintained by Pomelo Foundation Project). Vector DB connectors which are additionally supported in Semantic Kernel: - Azure AI Search - Chroma - Milvus - Pinecone - Qdrant - Redis - Weaviate Sources: - https://learn.microsoft.com/en-us/ef/core/providers/?tabs=dotnet-core-cli#current-providers ## Considered Options - Add new `Microsoft.SemanticKernel.Connectors.EntityFramework` connector. - Do not add `Microsoft.SemanticKernel.Connectors.EntityFramework` connector, but add a new connector for individual database when needed. ## Decision Outcome Based on the above investigation, the decision is not to add Entity Framework connector, but to add a new connector for individual database when needed. The reason for this decision is that Entity Framework providers do not uniformly support collection management operations and will require database specific code for key handling and object mapping. These factors will make use of an Entity Framework connector unreliable and it will not abstract away the underlying database. Additionally the number of vector databases that Entity Framework supports that Semantic Kernel does not have a memory connector for is very small. ================================================ FILE: docs/decisions/0052-python-ai-connector-new-abstract-methods.md ================================================ --- # These are optional elements.

These methods offer standardized interfaces for clients to engage with various models. > We will focus on `ChatCompletionClientBase` in this ADR but `TextCompletionClientBase` will be having a similar structure. With the introduction of function calling to many models, Semantic Kernel has implemented an amazing feature known as `auto function invocation`. This feature relieves developers from the burden of manually invoking the functions requested by the models, making the development process much smoother. Auto function invocation can cause a side effect where a single call to get_chat_message_contents or get_streaming_chat_message_contents may result in multiple calls to the model. However, this presents an excellent opportunity for us to introduce another layer of abstraction that is solely responsible for making a single call to the model. ## Benefits - To simplify the implementation, we can include a default implementation of `get_chat_message_contents` and `get_streaming_chat_message_contents`. - We can introduce common interfaces for tracing individual model calls, which can improve the overall monitoring and management of the system. - By introducing this layer of abstraction, it becomes more efficient to add new AI connectors to the system. ## Details ### Two new abstract methods > Revision: In order to not break existing customers who have implemented their own AI connectors, these two methods are not decorated with the `@abstractmethod` decorator, but instead throw an exception if they are not implemented in the built-in AI connectors. ```python async def _inner_get_chat_message_content( self, chat_history: ChatHistory, settings: PromptExecutionSettings ) -> list[ChatMessageContent]: raise NotImplementedError ``` ```python async def _inner_get_streaming_chat_message_content( self, chat_history: ChatHistory, settings: PromptExecutionSettings ) -> AsyncGenerator[list[StreamingChatMessageContent], Any]: raise NotImplementedError ``` ### A new `ClassVar[bool]` variable in `ChatCompletionClientBase` to indicate whether a connector supports function calling This class variable will be overridden in derived classes and be used in the default implementations of `get_chat_message_contents` and `get_streaming_chat_message_contents`. ```python class ChatCompletionClientBase(AIServiceClientBase, ABC): """Base class for chat completion AI services."""

This gives more control over model responses, allows to avoid model hallucinations and write simpler prompts without a need to be specific about response format. This ADR describes several options how to enable this functionality in .NET version of Semantic Kernel. A couple of examples how it's implemented in .NET and Python OpenAI SDKs: .NET OpenAI SDK: ```csharp ChatCompletionOptions options = new() { ResponseFormat = ChatResponseFormat.CreateJsonSchemaFormat( name: "math_reasoning", jsonSchema: BinaryData.FromString(""" { "type": "object", "properties": { "steps": { "type": "array", "items": { "type": "object", "properties": { "explanation": { "type": "string" }, "output": { "type": "string" } }, "required": ["explanation", "output"], "additionalProperties": false } }, "final_answer": { "type": "string" } }, "required": ["steps", "final_answer"], "additionalProperties": false } """), strictSchemaEnabled: true) }; ChatCompletion chatCompletion = await client.CompleteChatAsync( ["How can I solve 8x + 7 = -23?"], options); using JsonDocument structuredJson = JsonDocument.Parse(chatCompletion.ToString()); Console.WriteLine($"Final answer: {structuredJson.RootElement.GetProperty("final_answer").GetString()}"); Console.WriteLine("Reasoning steps:"); ``` Python OpenAI SDK: ```python class CalendarEvent(BaseModel): name: str date: str participants: list[str] completion = client.beta.chat.completions.parse( model="gpt-4o-2024-08-06", messages=[ {"role": "system", "content": "Extract the event information."}, {"role": "user", "content": "Alice and Bob are going to a science fair on Friday."}, ], response_format=CalendarEvent, ) event = completion.choices[0].message.parsed ``` ## Considered Options **Note**: All of the options presented in this ADR are not mutually exclusive - they can be implemented and supported simultaneously. ### Option #1: Use OpenAI.Chat.ChatResponseFormat object for ResponseFormat property (similar to .NET OpenAI SDK) This approach means that `OpenAI.Chat.ChatResponseFormat` object with JSON Schema will be constructed by user and provided to `OpenAIPromptExecutionSettings.ResponseFormat` property, and Semantic Kernel will pass it to .NET OpenAI SDK as it is. Usage example: ```csharp // Initialize Kernel Kernel kernel = Kernel.CreateBuilder() .AddOpenAIChatCompletion( modelId: "gpt-4o-2024-08-06", apiKey: TestConfiguration.OpenAI.ApiKey) .Build(); // Create JSON Schema with desired response type from string. ChatResponseFormat chatResponseFormat = ChatResponseFormat.CreateJsonSchemaFormat( name: "math_reasoning", jsonSchema: BinaryData.FromString(""" { "type": "object", "properties": { "Steps": { "type": "array", "items": { "type": "object", "properties": { "Explanation": { "type": "string" }, "Output": { "type": "string" } }, "required": ["Explanation", "Output"], "additionalProperties": false } }, "FinalAnswer": { "type": "string" } }, "required": ["Steps", "FinalAnswer"], "additionalProperties": false } """), strictSchemaEnabled: true); // Pass ChatResponseFormat in OpenAIPromptExecutionSettings.ResponseFormat property. var executionSettings = new OpenAIPromptExecutionSettings { ResponseFormat = chatResponseFormat }; // Get string result. var result = await kernel.InvokePromptAsync("How can I solve 8x + 7 = -23?", new(executionSettings)); Console.WriteLine(result.ToString()); // Output: // { // "Steps":[ // { // "Explanation":"Start with the equation: (8x + 7 = -23). The goal is to isolate (x) on one side of the equation. To begin, we need to remove the constant term from the left side of the equation.", // "Output":"8x + 7 = -23" // }, // { // "Explanation":"Subtract 7 from both sides of the equation to eliminate the constant from the left side.", // "Output":"8x + 7 - 7 = -23 - 7" // }, // { // "Explanation":"Simplify both sides: The +7 and -7 on the left will cancel out, while on the right side, -23 - 7 equals -30.", // "Output":"8x = -30" // }, // { // "Explanation":"Now, solve for (x) by dividing both sides of the equation by 8. This will isolate (x).", // "Output":"8x / 8 = -30 / 8" // }, // { // "Explanation":"Simplify the right side of the equation by performing the division: -30 divided by 8 equals -3.75.", // "Output":"x = -3.75" // } // ], // "FinalAnswer":"x = -3.75" // } ``` Pros: - This approach is already supported in Semantic Kernel without any additional changes, since there is a logic to pass `ChatResponseFormat` object as it is to .NET OpenAI SDK. - Consistent with .NET OpenAI SDK. Cons: - No type-safety. Information about response type should be manually constructed by user to perform a request. To access each response property, the response should be handled manually as well. It's possible to define a C# type and use JSON deserialization for response, but JSON Schema for request will still be defined separately, which means that information about the type will be stored in 2 places and any modifications to the type should be handled in 2 places. - Inconsistent with Python version, where response type is defined in a class and passed to `response_format` property by simple assignment. ### Option #2: Use C# type for ResponseFormat property (similar to Python OpenAI SDK) This approach means that `OpenAI.Chat.ChatResponseFormat` object with JSON Schema will be constructed by Semantic Kernel, and user just needs to define C# type and assign it to `OpenAIPromptExecutionSettings.ResponseFormat` property. Usage example: ```csharp // Define desired response models private sealed class MathReasoning { public List Steps { get; set; } public string FinalAnswer { get; set; } } private sealed class MathReasoningStep { public string Explanation { get; set; } public string Output { get; set; } } // Initialize Kernel Kernel kernel = Kernel.CreateBuilder() .AddOpenAIChatCompletion( modelId: "gpt-4o-2024-08-06", apiKey: TestConfiguration.OpenAI.ApiKey) .Build(); // Pass desired response type in OpenAIPromptExecutionSettings.ResponseFormat property. var executionSettings = new OpenAIPromptExecutionSettings { ResponseFormat = typeof(MathReasoning) }; // Get string result. var result = await kernel.InvokePromptAsync("How can I solve 8x + 7 = -23?", new(executionSettings)); // Deserialize string to desired response type. var mathReasoning = JsonSerializer.Deserialize(result.ToString())!; OutputResult(mathReasoning); // Output: // Step #1 // Explanation: Start with the given equation. // Output: 8x + 7 = -23 // Step #2 // Explanation: To isolate the term containing x, subtract 7 from both sides of the equation. // Output: 8x + 7 - 7 = -23 - 7 // Step #3 // Explanation: To solve for x, divide both sides of the equation by 8, which is the coefficient of x. // Output: (8x)/8 = (-30)/8 // Step #4 // Explanation: This simplifies to x = -3.75, as dividing -30 by 8 gives -3.75. // Output: x = -3.75 // Final answer: x = -3.75 ``` Pros: - Type safety. Users won't need to define JSON Schema manually as it will be handled by Semantic Kernel, so users could focus on defining C# types only. Properties on C# type can be added or removed to change the format of desired response. `Description` attribute is supported to provide more detailed information about specific property. - Consistent with Python OpenAI SDK. - Minimal code changes are required since Semantic Kernel codebase already has a logic to build a JSON Schema from C# type. Cons: - Desired type should be provided via `ResponseFormat = typeof(MathReasoning)` or `ResponseFormat = object.GetType()` assignment, which can be improved by using C# generics. - Response coming from Kernel is still a `string`, so it should be deserialized to desired type manually by user. ### Option #3: Use C# generics This approach is similar to Option #2, but instead of providing type information via `ResponseFormat = typeof(MathReasoning)` or `ResponseFormat = object.GetType()` assignment, it will be possible to use C# generics. Usage example: ```csharp // Define desired response models private sealed class MathReasoning { public List Steps { get; set; } public string FinalAnswer { get; set; } } private sealed class MathReasoningStep { public string Explanation { get; set; } public string Output { get; set; } } // Initialize Kernel Kernel kernel = Kernel.CreateBuilder() .AddOpenAIChatCompletion( modelId: "gpt-4o-2024-08-06", apiKey: TestConfiguration.OpenAI.ApiKey) .Build(); // Get MathReasoning result. var result = await kernel.InvokePromptAsync("How can I solve 8x + 7 = -23?"); OutputResult(mathReasoning); ``` Pros: - Simple usage, no need in defining `PromptExecutionSettings` and deserializing string response later. Cons: - Implementation complexity compared to Option #1 and Option #2: 1. Chat completion service returns a string, so deserialization logic should be added somewhere to return a type instead of string. Potential place: `FunctionResult`, as it already contains `GetValue` generic method, but it doesn't contain deserialization logic, so it should be added and tested. 2. `IChatCompletionService` and its methods are not generic, but information about the response type should still be passed to OpenAI connector. One way would be to add generic version of `IChatCompletionService`, which may introduce a lot of additional code changes. Another way is to pass type information through `PromptExecutionSettings` object. Taking into account that `IChatCompletionService` uses `PromptExecutionSettings` and not `OpenAIPromptExecutionSettings`, `ResponseFormat` property should be moved to the base execution settings class, so it's possible to pass the information about response format without coupling to specific connector. On the other hand, it's not clear if `ResponseFormat` parameter will be useful for other AI connectors. 3. Streaming scenario won't be supported, because for deserialization all the response content should be aggregated first. If Semantic Kernel will do the aggregation, then streaming capability will be lost. ## Out of scope Function Calling functionality is out of scope of this ADR, since Structured Outputs feature is already partially used in current function calling implementation by providing JSON schema with information about function and its arguments. The only remaining parameter to add to this process is `strict` property which should be set to `true` to enable Structured Outputs in function calling. This parameter can be exposed through `PromptExecutionSettings` type. By setting `strict` property to `true` for function calling process, the model should not create additional non-existent parameters or functions, which could resolve hallucination problems. On the other hand, enabling Structured Outputs for function calling will introduce additional latency during first request since the schema is processed first, so it may impact the performance, which means that this property should be well-documented. More information here: [Function calling with Structured Outputs](https://platform.openai.com/docs/guides/function-calling/function-calling-with-structured-outputs). ## Decision Outcome 1. Support Option #1 and Option #2, create a task for Option #3 to handle it separately. 2. Create a task for Structured Outputs in Function Calling and handle it separately. ================================================ FILE: docs/decisions/0054-processes.md ================================================ --- # These are optional elements.

At a high level, the structure of a business process is: - Starts with external event - Contains a collection of structured activities or tasks - A defined sequence of these tasks that produces a service or product that adds value - Serves a business goal In technical terms, a process is something that can be represented as a graph where nodes in the graph represent units of work and edges between nodes represent causal activations that may or may not also carry data. There are many examples of graph based workflow engines that are suitable for handling traditional enterprise processes. Examples include GitHub Actions & Workflows, Argo Workflows, Dapr Workflows, and many more. However, the additional requirements for integration with AI adds new requirements that may not be adequately supported by these frameworks. Features such as support for cycles in the graph, dynamically created nodes and edges, node and edge level metadata to support AI driven scenarios, and streamlined integration with AI orchestration are examples of things that are not fully supported by any of these. ## Decision Drivers - Customers should be able to leverage their existing investments in all supported languages of Semantic Kernel. - ``` ``` - Customers should be able to leverage their existing investments in infrastructure. - Customers should be able to collaborate with their business process peers to build up composable processes. - Customers should be able to use AI to enhance and streamline the steps within their business processes. - Customers should be able to control the process flow in a defined and repeatable way. - Customers should be able to easily model typical AI driven scenarios that may require cycles and dynamic edges. - Processes should be able to support short lived transient business processes as well as long lived business processes. - Processes should be able to be run locally, deployed as a single process or or deployed to a distributed service. - Processes should be able to run and debug locally without additional software or infrastructure. - Processes should be stateful and able resume from a paused state or a recoverable error. - Regulated Customers should be able to audit currently running or completed processes end to end. ## Considered Options ### Options #1: **_Build existing samples on top of existing workflow frameworks_**: This option was explored with frameworks such as Dapr Workflows, Argo, Durable Tasks, and others. Among the subset or these options that can support the technical requirements listed above, the main concern is the amount of overhead required to work with them. Many of these frameworks require a lot of code and infrastructure to get up and running and require special emulators to run locally which is undesirable. It's important to call out that this option is not mutually exclusive with the others, we may choose to build samples showing SK integrating with other workflow engines even if we choose to also go a different route. ### Options #2: **_Build SK Process library within an existing workflow framework_**: Of all the frameworks explored, the few that seem closest to meeting the technical requirements listed above are based on [Durable Tasks](https://github.com/Azure/durabletask). This includes things like Dapr Workflows, Azure Durable Functions, or the Durable Tasks Framework itself. Attempts to build a working solution on these frameworks resulted an awkward interface for basic scenarios due to the underlying structure of Durable Tasks where nodes are stateless and only the central orchestrator is stateful. While it is likely that many AI driven workflows could be modeled in this type of system, our exploration did not produce something we were happy with from a usability perspective. ### Options #3: **_Build SK Process library with a custom build workflow engine_**: Building a custom workflow engine might provide the cleanest integration but would require extensive resources and time that we don't have. Distributed workflow engines are products in and of themselves. ### Options #4: **_Build platform agnostic SK Process library with connectors for existing workflow frameworks_**: This is the chosen option. ## Decision Outcome **_Chosen option - #4_**: Build platform agnostic SK Process library with connectors for existing workflow frameworks. This was the only option that was ale to meet all the technical and scenario driven requirements. This option should allow for a simple and well-integrated interface into Semantic Kernel as well as the ability to support many existing distributed runtimes that will give our customers the flexibility to use their existing infrastructure and expertise. ### Components of the Process library The proposed architecture of a Process is based on a graph execution model where nodes, which we call Steps, perform work by invoking user defined Kernel Functions. Edges in the graph are defined from an event driven perspective and carry metadata about the event as well as a data payload containing the output of the Kernel Function invocation. Starting from the ground up, the components of a processes are: 1. **_KernelFunctions_**: The same KernelFunctions that our customers already know and use. Nothing new here. 1. **_Steps_**: Steps group one ore more KernelFunctions together into an object with optional user defined state. A step represents one unit of work within a process. Steps make the output of their work visible to other steps in the process by emitting events. This event based structure allows steps to be created without needing to know which process they are used in, allowing them to be reusable across multiple processes. 1. **_Process_**: A process groups multiple Steps together and defines the way that outputs flow from step to step. The process provides methods that allow the developer to define the routing of events that are emitted by steps by specifying the steps and associated KernelFunctions that should receive the event. ![Basic Process diagram](./diagrams/process/process_diagram_basic.png) Let's look at the code required to create a simple process. #### Step1 - Define the Steps: Steps are required to inherit from the abstract `KernelStepBase` type which allows for optional implementation of activation and deactivation lifecycle methods. ```csharp // Define UserInputStep with no state public class UserInputStep : KernelStepBase { public override ValueTask ActivateAsync() { return ValueTask.CompletedTask; } [KernelFunction()] public string GetUserInput(string userMessage) { return $"User: {userMessage}"; } } ``` The `UserInputStep` shown above is the minimum implementation of a step with one KernelFunction and no state management. The code in this step does not explicitly emit any events, however, execution of the `PrintUserMessage` will automatically emit an event indicating either the success of the execution with an associated result, or the failure of the execution with an associated error. Let's create a second step to take the user input and get a response from an LLM. This step will be stateful so that it can maintain an instance of `ChatHistory`. First define the class to use for tracking state: ```csharp public class ChatBotState { public ChatHistory ChatMessages { get; set; } = new(); } ``` Next define the step: ```csharp // Define ChatBotResponseStep with state of type ChatBotState public class ChatBotResponseStep : KernelStepBase { private readonly Kernel _kernel; internal ChatBotState? _state; public ChatBotResponseStep(Kernel kernel) { _kernel = kernel; } public override ValueTask ActivateAsync(ChatBotState state) { _state = state; _state.ChatMessages ??= new(); return ValueTask.CompletedTask; } [KernelFunction()] public async Task GetChatResponse(KernelStepContext context, string userMessage) { _state!.ChatMessages.Add(new(AuthorRole.User, userMessage)); IChatCompletionService chatService = _kernel.Services.GetRequiredService(); ChatMessageContent response = await chatService.GetChatMessageContentAsync(_state.ChatMessages); if (response != null) { _state.ChatMessages.Add(response!); } // emit event: assistantResponse context.PostEvent(new CloudEvent { Id = ChatBotEvents.AssistantResponseGenerated, Data = response }); } } ``` The `ChatBotResponseStep` is a bit more realistic than `UserInputStep` and show the following features: **_State management_**: The first thing to notice is that the state object is automatically created by the Process and injected into the `ActivateAsync` method. The Process will automatically persist the state object immediately after successful execution of any of the step's KernelFunctions. Processes use JSON serialization to persist and rehydrate state objects so we require that these types have a default constructor and only contain objects that are JSON serializable. **_Step Context_**: The `GetChatResponse` KernelFunction has an argument of type `KernelStepContext` which is automatically provided by the Process. This object provides functionality that allow the step to explicitly emit events such as `ChatBotEvents.AssistantResponseGenerated` in this case. The step context can also provide functionality for advances scenarios such as utilizing durable timers and dynamically adding new steps to the process. **_Cloud Events_**: Events in Steps and Processes make use of [Cloud Events](https://github.com/cloudevents/spec). Cloud Events provide an open source and industry standard specification for describing event data in common formats to provide interoperability across services, platforms and systems. This will allow Processes to emit/receive events to/from external systems without requiring custom connectors or mapping middleware. #### Step2 - Define the Process: Now that we have our steps defined, we can move on to defining our process. The first thing to do is to add the steps to the process... ```csharp KernelProcess process = new("ChatBot"); var userInputStep = process.AddStepFromType(isEntryPoint: true); var responseStep = process.AddStepFromType(); ``` The two steps steps created above have been added to our new `ChatBot` process and the `UserInputStep` has been declared as the entry point. This means that any events received by the process will be forwarded to this step. Now we need to define the flow of our process by describing which actions are triggered by events from our steps. ```csharp // When the userInput step completes, send the output to the llm response step userInputStep .OnFunctionResult(nameof(UserInputStep.GetUserInput)) .SendOutputTo(responseStep, nameof(ChatBotResponseStep.GetChatResponse), "userMessage"); ``` In the code above, `userInputStep.OnFunctionResult(nameof(UserInputStep.GetUserInput))` selects the event that is emitted by the process on successful execution of the `GetUserInput` KernelFunction in the step instance referenced by `userInputStep`. It then returns a builder type object that provides actions based on the context. In this case the `SendOutputTo(responseStep, nameof(ChatBotResponseStep.GetChatResponse), "userMessage")` action is used to forward the event data to the `userMessage` parameter of the `GetChatResponse` KernelFunction on the step instance referenced by `responseStep`. One of the key takeaways here is that events emitted by a given step can be selected and forwarded to **_a specific parameter of a specific KernelFunction_** within another step. Event data sent to parameters of KernelFunctions are queued until all of the required parameters of the function have received input, at which point the function will be invoked. #### Step 3 - Get output from the Process: Now that we've defined our process, we would like to inspect the final result that it produces. In many cases the result of the process will be written to a database or queue or some other internal system and that's all that's needed. In some cases however, such as in the case of a process running in a server as the result of a synchronous REST call, there is a need to extract the result from the finished process so that it can be returned to the caller. In these cases handler functions can be registered on the process to be triggered by a specific event. Let's wire up the process above to run a handler function when the `ChatBotResponseStep` step completes. ```csharp process.OnEvent(ChatBotEvents.AssistantResponseGenerated).Run((CloudEvent e) => { result = (int)e.Data!; Console.WriteLine($"Result: {result}"); }); ``` A key thing to notice is that the event emitted by the `ChatBotResponseStep` within the processes was also be emitted from the processes itself which allows us to register a handler for it. All events within a process will bubble up out of the process to the parent which may be the program running the process or may be another process. This pattern allows for nested processes where an existing process can be used as a step in another process. #### Step 4 - Process object model: The instance of `KernelProcess` that we've created is nothing more than an object model that describes the underlying graph. It contains a collection of steps that in turn contain a collection of edges. This object model is designed to be serializable in human readable formats such as Json/Yaml as allows the process definition to be decoupled from the system in which the process runs. ```json { "EntryPointId": "efbfc9ca0c1942a384d21402c9078784", "Id": "19f669adfa5b40688e818e400cb9750c", "Name": "NestedChatBot", "StepType": "SemanticKernel.Processes.Core.KernelProcess, SemanticKernel.Processes.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null", "StateType": "SemanticKernel.Processes.Core.DefaultState, SemanticKernel.Processes.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null", "OutputEdges": {}, "StepProxies": [ { "Id": "6fa2d6b513464eb5a4daa9b5ebc1a956", "Name": "UserInputStep", "StepType": "SkProcess.Orleans.Silo.UserInputStep, SkProcess.Orleans.Silo, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null", "StateType": "SkProcess.Orleans.Silo.UserInputState, SkProcess.Orleans.Silo, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null", "OutputEdges": { "UserInputStep_6fa2d6b513464eb5a4dxa9b5ebc1a956.exit": [ { "SourceId": "6fa2d6b513464eb5a4dxa9b5ebc1a956", "OutputTargets": [ { "StepId": "End", "FunctionName": "", "ParameterName": "" } ] } ], "UserInputStep_6fa2d6b513464eb5a4dxa9b5ebc1a956.userInputReceived": [ { "SourceId": "6fa2d6b513464eb5a4daa9b5ebc1a956", "OutputTargets": [ { "StepId": "5035d41383314343b99ebf6e1a1a1f99", "FunctionName": "GetChatResponse", "ParameterName": "userMessage" } ] } ] } }, { "Id": "5035d41383314343b99ebf6e1a1a1f99", "Name": "AiResponse", "StepType": "SemanticKernel.Processes.Core.KernelProcess, SemanticKernel.Processes.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null", "StateType": "SemanticKernel.Processes.Core.DefaultState, SemanticKernel.Processes.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null", "OutputEdges": { "AiResponse_5035d41383314343b99ebf6e1a1a1f99.TransformUserInput.OnResult": [ { "SourceId": "5035d41383314343b99ebf6e1a1a1f99", "OutputTargets": [ { "StepId": "6fa2d6b513464eb5a4daa9b5ebc1a956", "FunctionName": "GetUserInput", "ParameterName": "" } ] } ] } } ] } ``` #### Step 5 - Run the Process: Running a Process requires using a "connector" to a supported runtime. As part of the core packages we will include an in-process runtime that is capable of of running a process locally on a dev machine or in a server. This runtime will initially use memory or file based persistence and will allow for easy development and debugging. Additionally we will provide support for [Orleans](https://learn.microsoft.com/en-us/dotnet/orleans/overview) and [Dapr Actor](https://docs.dapr.io/developing-applications/building-blocks/actors/actors-overview/) based runtimes which will allow customers to easily deploy processes as a distributed and highly scalable cloud based system. ### Packages The following packages will be created for Processes: - **_Microsoft.SemanticKernel.Process.Abstractions_** Contains common interfaces and DTOs used by all other packages. - **_Microsoft.SemanticKernel.Process.Core_** Contains core functionality for defining Steps and Processes. - **_Microsoft.SemanticKernel.Process.Server_** Contains the in-process runtime. - **_Microsoft.SemanticKernel.Process_** Contains Microsoft.SemanticKernel.Process.Abstractions, Microsoft.SemanticKernel.Process.Core, and Microsoft.SemanticKernel.Process.Server - **_Microsoft.SemanticKernel.Process.Orleans_** Contains the Orleans based runtime. - **_Microsoft.SemanticKernel.Process.Dapr_** Contains the Dapr based runtime. ## More Information ### Process runtime architecture: In validation of the proposed solution, two runtimes were created, one for the local/server scenario and one for the distributed actor scenario using Orleans. Both of these implementation were based on the [Pregel Algorithm](https://kowshik.github.io/JPregel/pregel_paper.pdf) for large-scale graph processing. This algorithm is well tested and well suited for single machine scenarios as well as distributed systems. More information on how the Pregel algorithm works can be found in the following links. ================================================ FILE: docs/decisions/0055-dotnet-azureopenai-stable-version-strategy.md ================================================ --- # These are optional elements.

This also requires us to rethink how we are going to proceed with our strategy for the following versions of our connectors. | Name | SDK NameSpace | Semantic Kernel NameSpace | | ------------------- | --------------- | ----------------------------------------------- | | OpenAI (OAI) | OpenAI | Microsoft.SemanticKernel.Connectors.OpenAI | | Azure OpenAI (AOAI) | Azure.AI.OpenAI | Microsoft.SemanticKernel.Connectors.AzureOpenAI | ## Decision Drivers - Minimize the impact of customers - Allow customers to use either GA or Beta versions of OpenAI and Azure.AI.OpenAI packages - Keep a clear message on our strategy - Keep the compatibility with the previous versions - Our package versioning should make it clear which version of OpenAI or Azure.AI.OpenAI packages we depend on - Follow the Semantic Kernel versioning strategy in a way that accommodates well with other SDK version strategies. ## Considered Options 1. **Keep As-Is** - Target only preview packages. 2. **Preview + GA versioning** (Create a new version (GA + pre-release) side by side of the Azure OpenAI and OpenAI Connectors). 3. **Stop targeting preview packages**, only target GA packages moving forward. ## 1. Keep As-Is - Target only preview packages This option will keep the current strategy of targeting only preview packages, which will keep the compatibility with the previous versions and new GA targeting versions and pipelines for our customers. This option has the least impact on our users and our pipeline strategy. Today all customers that are already using Azure OpenAI Connector have their pipelines configured to use the preview packages. ```mermaid %%{init: { 'logLevel': 'debug', 'theme': 'base', 'gitGraph': {'showBranches': true, 'showCommitLabel':true,'mainBranchName': 'SemanticKernel'}} }%% gitGraph TB: checkout SemanticKernel commit id:"SK 1.21" branch OpenAI commit id:"OAI 2.0-beta.12" branch AzureOpenAI commit id:"AOAI 2.0-beta.6" checkout SemanticKernel merge OpenAI id:"SK OAI 1.22" merge AzureOpenAI id:"SK AOAI 1.22" checkout OpenAI commit id:"OAI 2.0 GA" checkout AzureOpenAI merge OpenAI id:"AOAI 2.0 GA" checkout SemanticKernel commit id:"Skipped GA's" checkout OpenAI commit id:"OAI 2.1-beta.1" checkout AzureOpenAI commit id:"AOAI 2.1-beta.1" checkout SemanticKernel merge OpenAI id:"SK OAI 1.23" merge AzureOpenAI id:"SK AOAI 1.23" ``` Pros: - No changes in strategy. (Least impact on customers) - Keep the compatibility with the previous versions and new GA targeting versions and pipelines. - Compatible with our previous strategy of targeting preview packages. - Azure and OpenAI SDKs will always be in sync with new GA versions, allowing us to keep the targeting preview with the latest GA patches. Cons: - There won't be a SK connector version that targets a stable GA package for OpenAI or AzureOpenAI. - New customers that understand and target GA only available features and also have a strict requirement for dependent packages to be also GA will not be able to use the SK connector. (We don't have an estimate but this could be very small compared to the number of customers that are already OK on using the preview Azure SDK OpenAI SDK available for the past 18 months) - Potential unexpected breaking changes introduced by OpenAI and Azure.AI.OpenAI beta versions that eventually we might be passing on due to their dependency. ## 2. Preview + GA versioning This option we will introduce pre-release versions of the connectors: 1. General Available (GA) versions of the connector will target a GA version of the SDK. 2. Pre-release versions of the connector will target a pre-release versions of the SDK. This option has some impact for customers that were targeting strictly only GA packages on their pipeline while using preview features that are not available anymore on underlying SDK GA versions. All preview only functionalities not available in the SDK will be Annotate in Semantic kernel connectors with an Experimental `SKEXP0011` dedicated identifier attribute, to identify and clarify the potential impact when attempting to move to a `GA` package. Those annotations will be removed as soon as they are officially supported on the GA version of the SDK. ```mermaid %%{init: { 'logLevel': 'debug', 'theme': 'base', 'gitGraph': {'showBranches': true, 'showCommitLabel':true,'mainBranchName': 'SemanticKernel'}} }%% gitGraph TB: checkout SemanticKernel commit id:"SK 1.21" branch OpenAI commit id:"OAI 2.0-beta.12" branch AzureOpenAI commit id:"AOAI 2.0-beta.6" checkout SemanticKernel merge OpenAI id:"SK OAI 1.22-beta" merge AzureOpenAI id:"SK AOAI 1.22-beta" checkout OpenAI commit id:"OAI 2.0 GA" checkout AzureOpenAI merge OpenAI id:"AOAI 2.0 GA" checkout SemanticKernel merge OpenAI id:"SK OAI 1.23" merge AzureOpenAI id:"SK AOAI 1.23" checkout OpenAI commit id:"OAI 2.1-beta.1" checkout AzureOpenAI merge OpenAI id:"AOAI 2.1-beta.1" checkout SemanticKernel merge OpenAI id:"SK OAI 1.23-beta" merge AzureOpenAI id:"SK AOAI 1.23-beta" checkout OpenAI commit id:"OAI 2.1-beta.2" checkout AzureOpenAI merge OpenAI id:"AOAI 2.1-beta.2" checkout SemanticKernel merge OpenAI id:"SK OAI 1.24-beta" checkout SemanticKernel merge AzureOpenAI id:"SK AOAI 1.24-beta" ``` Pros: - We send a clear message moving forward regarding what Azure and OpenAI consider stable and what is not, exposing only stable features from those SDKs in what we previously were considering as GA available features. - New customers that have a strict requirement for dependent packages to be also GA will be able to use the SK connector. - We will be able to have preview versions of Connectors for new features that are not yet GA without impacting the GA versions of the Connectors. Cons: - This change our strategy for versioning, needing to some clear clarification and communication for the first releases to mitigate impact or smooth the transition. - Customers that were using `OpenAI` and `AzureOpenAI` preview only features available in previous SK GA packages will need to update their pipelines to target only future SK pre-release versions. - Small Overhead to maintain two versions of the connectors. ### Version and Branching Strategy Create a special release branch for the targeted `GA` version of the connector, keeping it in the record for that release with all modifications/removal that all the other projects need to make to work with the stable release this will be also a important guideline on where and when to add/remove the `SKEXP0011` exceptions from API's samples. We will follow our own version cadence with the addition of `beta` prefix for `beta` versions of the underlying SDKs. | Seq | OpenAI Version | Azure OpenAI Version | Semantic Kernel Version1 | Branch | | --- | -------------- | -------------------- | ----------------------------------- | --------------- | | 1 | 2.0.0 | 2.0.0 | 1.25.0 | releases/1.25.0 | | 2 | 2.1.0-beta.1 | 2.1.0-beta.1 | 1.26.0-beta | main | | 3 | 2.1.0-beta.3 | 2.1.0-beta.2 | 1.27.0-beta | main | | 4 | No changes | No changes | 1.27.1-beta**2** | main | | 5 | 2.1.0 | 2.1.0 | 1.28.0 | releases/1.28.0 | | 6 | 2.2.0-beta.1 | 2.1.0-beta.1 | 1.29.0-beta | main | 1. Versions apply for the **Connectors packages** and the **Semantic Kernel meta package**. 2. No changes on the SDKs but other minor changes to Semantic Kernel code base that needed a version update. ### Optional Smoothing Transition In the intend to smooth the transition and mitigate impact on customers using preview features on SK GA packages straight away we would provide a notice period where we give the time for customers adapt to the `preview` vs `GA` future releases of the connector packages. While for the notice duration we would maintain our strategy with the **Keep As-Is** option before shifting to the **Preview + GA versioning** option. ## 3. Stop targeting preview packages > [!WARNING] > This option is not recommended but needs to be considered. This option will stop targeting preview packages, being strict with our 1.0 GA strategy, not exposing our customers to non-GA SDK features. As big features like Azure Assistants are still in preview, this option will have a big impact on our customers if they were targeting Agent frameworks and other important features that are not yet General Available. Described in [here](https://github.com/Azure/azure-sdk-for-net/releases/tag/Azure.AI.OpenAI_2.0.0) > Assistants, Audio Generation, Batch, Files, Fine-Tuning, and Vector Stores are not yet included in the GA surface; they will continue to be available in preview library releases and the originating Azure OpenAI Service api-version labels. ```mermaid %%{init: { 'logLevel': 'debug', 'theme': 'base', 'gitGraph': {'showBranches': true, 'showCommitLabel':true,'mainBranchName': 'SemanticKernel'}} }%% gitGraph TB: checkout SemanticKernel commit id:"SK 1.21.1" branch OpenAI commit id:"OAI 2.0.0-beta.12" branch AzureOpenAI commit id:"AOAI 2.0.0-beta.6" checkout OpenAI commit id:"OAI 2.0.0 GA" checkout SemanticKernel merge OpenAI id:"SK OAI 1.22.0" checkout AzureOpenAI merge OpenAI id:"AOAI 2.0.0 GA" checkout SemanticKernel merge AzureOpenAI id:"SK AOAI 1.22.0" checkout OpenAI commit id:"OAI 2.1.0-beta.1" checkout AzureOpenAI commit id:"AOAI 2.1.0-beta.1" checkout OpenAI commit id:"OAI 2.1.0 GA" checkout SemanticKernel merge OpenAI id:"SK OAI 1.23.0" checkout AzureOpenAI commit id:"AOAI 2.1.0 GA" checkout SemanticKernel merge AzureOpenAI id:"SK AOAI 1.23.0" ``` Pros: - As we have been only deploying GA versions of the connector, strictly we would be following a responsible GA only approach with GA SK packages not exposing customers to preview features as GA features at all. Cons: - Big impact on customers that are targeting preview features with no option to resort to a preview version of the connector. - This strategy will render the use of the Semantic Kernel with Assistants and any other preview feature in Azure impractical. ## Decision Outcome Chosen option: **Keep as is** As the current AI landscape for SDK is a fast changing environment, we need to be able be update and at the same time avoid as much as possible mix our current versioning strategy also minimizing the impact on customers. We decided on **Keep As-Is** option for now, and we may reconsider **Preview + GA versioning** option in the future when that decision doesn't bring big impact of lack of important functionality already used by our customer base. ================================================ FILE: docs/decisions/0056-python-streaming-content-for-token-usage.md ================================================ --- # These are optional elements. Feel free to remove any of them. status: { accepted } contact: { Tao Chen } date: { 2024-09-18 } deciders: { Tao Chen } consulted: { Eduard van Valkenburg, Evan Mattson } informed: { Eduard van Valkenburg, Evan Mattson, Ben Thomas } --- # Streaming Contents for Token Usage Information (Semantic Kernel Python) ## Context and Problem Statement Currently, `StreamingChatMessageContent` (inherits from `StreamingContentMixin`) in Semantic Kernel requires a choice index to be specified. This creates a limitation since the token usage information from **OpenAI's streaming chat completion** API will be returned in the last chunk where the choices field will be empty, which leads to an unknown choice index for the chunk. For more information, please refer to the [OpenAI API documentation](https://platform.openai.com/docs/api-reference/chat/create) and look for the `stream_options` field. > The token usage information returned in the last chunk is the **total** token usage for the chat completion request regardless of the number of choices specified. That being said, there will be only one chunk containing the token usage information in the streaming response even when multiple choices are requested. Our current data structure for `StreamingChatMessageContent`: ```Python # semantic_kernel/content/streaming_chat_message_content.py class StreamingChatMessageContent(ChatMessageContent, StreamingContentMixin): # semantic_kernel/content/chat_message_content.py class ChatMessageContent(KernelContent): content_type: Literal[ContentTypes.CHAT_MESSAGE_CONTENT] = Field(CHAT_MESSAGE_CONTENT_TAG, init=False) # type: ignore tag: ClassVar[str] = CHAT_MESSAGE_CONTENT_TAG role: AuthorRole name: str | None = None items: list[Annotated[ITEM_TYPES, Field(..., discriminator=DISCRIMINATOR_FIELD)]] = Field(default_factory=list) encoding: str | None = None finish_reason: FinishReason | None = None # semantic_kernel/content/streaming_content_mixin.py class StreamingContentMixin(KernelBaseModel, ABC): choice_index: int # semantic_kernel/content/kernel_content.py class KernelContent(KernelBaseModel, ABC): inner_content: Any | None = None ai_model_id: str | None = None metadata: dict[str, Any] = Field(default_factory=dict) ``` ## Proposal 1 In non-streaming responses, the token usage is returned as part of the response from the model along with the choices that can be more than one. We then parse the choices into individual `ChatMessageContent`s, with each containing the token usage information, even though the token usage is for the entire response, not just the individual choice. Considering the same strategy, all choices from the streaming response should contain the token usage information when they are eventually concatenated by their `choice_index`. Since we know the number of choices requested, we can perform the following steps: 1. Replicate the last chunk for each choice requested to create a list of `StreamingChatMessageContent`s, with the token usage information included in the metadata. 2. Assign a choice index to each replicated chunk, starting from 0. 3. Stream the replicated chunks in a list back to the client. ### Additional considerations Currently, when two `StreamingChatMessageContent`s are "added" together, the metadata is not merged. We need to ensure that the metadata is merged when the chunks are concatenated. When there are conflicting metadata keys, the metadata from the second chunk should overwrite the metadata from the first chunk: ```Python class StreamingChatMessageContent(ChatMessageContent, StreamingContentMixin): ... def __add__(self, other: "StreamingChatMessageContent") -> "StreamingChatMessageContent": ... return StreamingChatMessageContent( ..., metadata=self.metadata | other.metadata, ... ) ... ``` ### Risks There are no breaking changes and known risks associated with this proposal. ## Proposal 2 We allow the choice index to be optional in the `StreamingContentMixin` class. This will allow the choice index to be `None` when the token usage information is returned in the last chunk. The choice index will be set to `None` in the last chunk, and the client can handle the token usage information accordingly. ```Python # semantic_kernel/content/streaming_content_mixin.py class StreamingContentMixin(KernelBaseModel, ABC): choice_index: int | None ``` This is a simpler solution compared to Proposal 1, and it is more in line with what the OpenAI API returns, that is the token usage is not associated with any specific choice. ### Risks This is potentially a breaking change since the `choice_index` field is currently required. This approach also makes streaming content concatenation more complex since the choice index will need to be handled differently when it is `None`. ## Proposal 3 We will merge `ChatMessageContent` and `StreamingChatMessageContent` into a single class, `ChatMessageContent`, and mark `StreamingChatMessageContent` as deprecated. The `StreamingChatMessageContent` class will be removed in a future release. Then we apply the either [Proposal 1](#proposal-1) or [Proposal 2](#proposal-2) to the `ChatMessageContent` class to handle the token usage information. This approach simplifies the codebase by removing the need for a separate class for streaming chat messages. The `ChatMessageContent` class will be able to handle both streaming and non-streaming chat messages. ```Python # semantic_kernel/content/streaming_chat_message_content.py @deprecated("StreamingChatMessageContent is deprecated. Use ChatMessageContent instead.") class StreamingChatMessageContent(ChatMessageContent): pass # semantic_kernel/content/chat_message_content.py class ChatMessageContent(KernelContent): ... # Add the choice_index field to the ChatMessageContent class and make it optional choice_index: int | None # Add the __add__ method to merge the metadata when two ChatMessageContent instances are added together. This is currently an abstract method in the `StreamingContentMixin` class. def __add__(self, other: "ChatMessageContent") -> "ChatMessageContent": ... return ChatMessageContent( ..., choice_index=self.choice_index, ... ) # Add the __bytes__ method to return the bytes representation of the ChatMessageContent instance. This is currently an abstract method in the `StreamingContentMixin` class. def __bytes__(self) -> bytes: ... ``` ### Risks We are unifying the returned data structure for streaming and non-streaming chat messages, which may lead to confusion for developers initially, especially if they are not aware of the deprecation of the `StreamingChatMessageContent` class, or they came from SK .Net. It may also create a sharper learning curve if developers started with Python but later move to .Net for production. This approach also introduces breaking changes to our AI connectors as the returned data type will be different. > We will also need to update the `StreamingTextContent` and `TextContent` in a similar way too for this proposal. ## Proposal 4 Similar to [Proposal 3](#proposal-3), we will merge `ChatMessageContent` and `StreamingChatMessageContent` into a single class, `ChatMessageContent`, and mark `StreamingChatMessageContent` as deprecated. In addition, we will introduce another a new mixin called `ChatMessageContentConcatenationMixin` to handle the concatenation of two `ChatMessageContent` instances. Then we apply the either [Proposal 1](#proposal-1) or [Proposal 2](#proposal-2) to the `ChatMessageContent` class to handle the token usage information. ```Python # semantic_kernel/content/streaming_chat_message_content.py @deprecated("StreamingChatMessageContent is deprecated. Use ChatMessageContent instead.") class StreamingChatMessageContent(ChatMessageContent): pass # semantic_kernel/content/chat_message_content.py class ChatMessageContent(KernelContent, ChatMessageContentConcatenationMixin): ... # Add the choice_index field to the ChatMessageContent class and make it optional choice_index: int | None # Add the __bytes__ method to return the bytes representation of the ChatMessageContent instance. This is currently an abstract method in the `StreamingContentMixin` class. def __bytes__(self) -> bytes: ... class ChatMessageContentConcatenationMixin(KernelBaseModel, ABC): def __add__(self, other: "ChatMessageContent") -> "ChatMessageContent": ... ``` This approach separates the concerns of the `ChatMessageContent` class and the concatenation logic into two separate classes. This can help to keep the codebase clean and maintainable. ### Risks Same as [Proposal 3](#proposal-3). ## Decision Outcome To minimize the impact on customers and the existing codebase, we will go with [Proposal 1](#proposal-1) to handle the token usage information in the OpenAI streaming responses. This proposal is backward compatible and aligns with the current data structure for non-streaming responses. We will also ensure that the metadata is merged correctly when two `StreamingChatMessageContent` instances are concatenated. This approach also makes sure the token usage information will be associated to all choices in the streaming response. [Proposal 3](#proposal-3) and [Proposal 4](#proposal-4) are still valid but perhaps premature at this stage as most services still return objects of different types for streaming and non-streaming responses. We will keep them in mind for future refactoring efforts. ================================================ FILE: docs/decisions/0057-python-structured-output.md ================================================ --- # These are optional elements.

While JSON mode helps improve model reliability in generating valid JSON outputs, it falls short of enforcing strict adherence to specific schemas. This limitation has led developers to employ workarounds—such as custom open-source tools, iterative prompting, and retries—to ensure that the output conforms to required formats. To address this issue, OpenAI has introduced **Structured Outputs**—a feature designed to ensure that model-generated outputs conform precisely to developer-specified JSON Schemas. This advancement allows developers to build more robust applications by providing guarantees that AI outputs will match predefined structures, improving interoperability with downstream systems. In recent evaluations, the new GPT-4o-2024-08-06 model with Structured Outputs demonstrated a perfect 100% score in adhering to complex JSON schemas, compared to GPT-4-0613, which scored less than 40%. Structured Outputs streamline the process of generating reliable structured data from unstructured inputs, a core need in various AI-powered applications such as data extraction, automated workflows, and function calling. --- ## Problem Statement Developers building AI-driven solutions using the OpenAI API often face challenges when extracting structured data from unstructured inputs. Ensuring model outputs conform to predefined JSON schemas is critical for creating reliable and interoperable systems. However, current models, even with JSON mode, do not guarantee schema conformity, leading to inefficiencies, errors, and additional development overhead in the form of retries and custom tools. With the introduction of Structured Outputs, OpenAI models are now able to strictly adhere to developer-provided JSON schemas. This feature eliminates the need for cumbersome workarounds and provides a more streamlined, efficient way to ensure consistency and reliability in model outputs. Integrating Structured Outputs into the Semantic Kernel orchestration SDK will enable developers to create more powerful, schema-compliant applications, reduce errors, and improve overall productivity. ## Out of scope This ADR will focus on the `structured outputs` `response_format` and not on the function calling aspect. A subsequent ADR will be created around that in the future. ## Using Structured Outputs ### Response Format OpenAI offers a new way to set the `response_format` on the prompt execution settings attribute: ```python from pydantic import BaseModel from openai import OpenAI class Step(BaseModel): explanation: str output: str class MathResponse(BaseModel): steps: list[Step] final_answer: str client = AsyncOpenAI() completion = await client.beta.chat.completions.parse( model="gpt-4o-2024-08-06", messages=[ {"role": "system", "content": "You are a helpful math tutor."}, {"role": "user", "content": "solve 8x + 31 = 2"}, ], response_format=MathResponse, # for example, a Pydantic model type is directly configured ) message = completion.choices[0].message if message.parsed: print(message.parsed.steps) print(message.parsed.final_answer) else: print(message.refusal) ``` For non-Pydantic models, SK will need to use the `KernelParameterMetadata`'s `schema_data` attribute. This represents the JSON Schema of the SK function: ```json { "type": "object", "properties": { "steps": { "type": "array", "items": { "type": "object", "properties": { "explanation": { "type": "string" }, "output": { "type": "string" } }, "required": ["explanation", "output"], "additionalProperties": false } }, "final_answer": { "type": "string" } }, "required": ["steps", "final_answer"], "additionalProperties": false } ``` to create the required `json_schema` `response_format`: ```json "response_format": { "type": "json_schema", "json_schema": { "name": "math_response", "strict": true, "schema": { // start of existing SK `schema_data` from above "type": "object", "properties": { "steps": { "type": "array", "items": { "type": "object", "properties": { "explanation": { "type": "string" }, "output": { "type": "string" } }, "required": ["explanation", "output"], "additionalProperties": false } }, "final_answer": { "type": "string" } }, "required": ["steps", "final_answer"], "additionalProperties": false } // end of existing SK `schema_data` from above } } ``` #### Handling the Streaming Response Format The new `structured output` response format is in beta, and the streaming chat completion code should be handled like this (which is different than our current streaming chat completion call): ```python async with client.beta.chat.completions.stream( model='gpt-4o-mini', messages=messages, tools=[pydantic_function_tool(SomeClass)], ) as stream: async for event in stream: if event.type == 'content.delta': print(event.delta, flush=True, end='') elif event.type == 'content.done': content = event.content elif event.type == 'tool_calls.function.arguments.done': tool_calls.append({'name': event.name, 'parsed_arguments': event.parsed_arguments}) print(content) ``` The `OpenAIHandler` class, which manages chat completions, will need to handle the new structured output streaming method, similar to: ```python async def _initiate_chat_stream(self, settings: OpenAIChatPromptExecutionSettings): """Initiate the chat stream request and return the stream.""" return self.client.beta.chat.completions.stream( model='gpt-4o-mini', messages=settings.messages, tools=[pydantic_function_tool(SomeClass)], ) async def _handle_chat_stream(self, stream): """Handle the events from the chat stream.""" async for event in stream: if event.type == 'content.delta': chunk_metadata = self._get_metadata_from_streaming_chat_response(event) yield [ self._create_streaming_chat_message_content(event, event.delta, chunk_metadata) ] elif event.type == 'tool_calls.function.arguments.done': # Handle tool call results as needed tool_calls.append({'name': event.name, 'parsed_arguments': event.parsed_arguments}) # An example calling method could be: async def _send_chat_stream_request(self, settings: OpenAIChatPromptExecutionSettings): """Send the chat stream request and handle the stream.""" async with await self._initiate_chat_stream(settings) as stream: async for chunk in self._handle_chat_stream(stream): yield chunk ``` The method for handling the stream or non-streaming chat completion will be based on the `response_format` execution setting -- whether it uses a Pydantic model type or a JSON Schema. Since the `response_format` chat completion method differs from the current chat completion approach, we will need to maintain separate implementations for handling chat completions until OpenAI officially integrates the `response_format` method into the main library upon its graduation. ### Callouts - The `structured output` `response_format` is limited to a single object type at this time. We will use a Pydantic validator to make sure a user is only specifying the proper type/amount of objects: ```python @field_validator("response_format", mode="before") @classmethod def validate_response_format(cls, value): """Validate the response_format parameter.""" if not isinstance(value, dict) and not (isinstance(value, type) and issubclass(value, BaseModel)): raise ServiceInvalidExecutionSettingsError( "response_format must be a dictionary or a single Pydantic model class" ) return value ``` - We need to provide good (and easy-to-find) documentation to let users and developers know which OpenAI/AzureOpenAI models/API-versions support `structured outputs`. ### Chosen Solution - Response Format: Since there's a single approach here, we should integrate a clean implementation to define both streaming and non-streaming chat completions using our existing `OpenAIChatCompletionBase` and `OpenAIHandler` code. ================================================ FILE: docs/decisions/0058-vector-search-design.md ================================================ --- # These are optional elements.

Support searching by Vector. 1. Support Vectors with different types of elements and allow extensibility to support new types of vector in future (e.g. sparse). 1. Support searching by Text. This is required to support the scenario where the service does the embedding generation or the scenario where the embedding generation is done in the pipeline. 1. Allow extensibility to search by other modalities, e.g. image. 1. Allow extensibility to do hybrid search. 1. Allow basic filtering with possibility to extend in future. 1. Provide extension methods to simplify search experience. ## Interface The vector search interface takes a `VectorSearchQuery` object. This object is an abstract base class that has various subclasses representing different types of search. ```csharp interface IVectorSearch { IAsyncEnumerable> SearchAsync( VectorSearchQuery vectorQuery, CancellationToken cancellationToken = default); } ``` Each `VectorSearchQuery` subclass represents a specific type of search. The possible variations are restricted by the fact that `VectorSearchQuery` and all subclasses have internal constructors. Therefore, a developer cannot create a custom search query type and expect it to be executable by `IVectorSearch.SearchAsync`. Having subclasses in this way though, allows each query to have different parameters and options. ```csharp // Base class for all vector search queries. abstract class VectorSearchQuery( string queryType, object? searchOptions) { public static VectorizedSearchQuery CreateQuery(TVector vector, VectorSearchOptions? options = default) => new(vector, options); public static VectorizableTextSearchQuery CreateQuery(string text, VectorSearchOptions? options = default) => new(text, options); // Showing future extensibility possibilities. public static HybridTextVectorizedSearchQuery CreateHybridQuery(TVector vector, string text, HybridVectorSearchOptions? options = default) => new(vector, text, options); public static HybridVectorizableTextSearchQuery CreateHybridQuery(string text, HybridVectorSearchOptions? options = default) => new(text, options); } // Vector search using vector. class VectorizedSearchQuery( TVector vector, VectorSearchOptions? searchOptions) : VectorSearchQuery; // Vector search using query text that will be vectorized downstream. class VectorizableTextSearchQuery( string queryText, VectorSearchOptions? searchOptions) : VectorSearchQuery; // Hybrid search using a vector and a text portion that will be used for a keyword search. class HybridTextVectorizedSearchQuery( TVector vector, string queryText, HybridVectorSearchOptions? searchOptions) : VectorSearchQuery; // Hybrid search using text that will be vectorized downstream and also used for a keyword search. class HybridVectorizableTextSearchQuery( string queryText, HybridVectorSearchOptions? searchOptions) : VectorSearchQuery // Options for basic vector search. public class VectorSearchOptions { public static VectorSearchOptions Default { get; } = new VectorSearchOptions(); public VectorSearchFilter?

HybridFieldName { get; init; } } ``` To simplify calling search, without needing to call CreateQuery we can use extension methods. e.g. Instead of `SearchAsync(VectorSearchQuery.CreateQuery(vector))` you can call `SearchAsync(vector)` ```csharp public static class VectorSearchExtensions { public static IAsyncEnumerable> SearchAsync( this IVectorSearch search, TVector vector, VectorSearchOptions? options = default, CancellationToken cancellationToken = default) where TRecord : class { return search.SearchAsync(new VectorizedSearchQuery(vector, options), cancellationToken); } public static IAsyncEnumerable> SearchAsync( this IVectorSearch search, string searchText, VectorSearchOptions? options = default, CancellationToken cancellationToken = default) where TRecord : class { return search.SearchAsync(new VectorizableTextSearchQuery(searchText, options), cancellationToken); } // etc... } ``` ## Usage Examples ```csharp public sealed class Glossary { [VectorStoreRecordKey] public ulong Key { get; set; } [VectorStoreRecordData] public string Category { get; set; } [VectorStoreRecordData] public string Term { get; set; } [VectorStoreRecordData] public string Definition { get; set; } [VectorStoreRecordVector(1536)] public ReadOnlyMemory DefinitionEmbedding { get; set; } } public async Task VectorSearchAsync(IVectorSearch vectorSearch) { var searchEmbedding = new ReadOnlyMemory(new float[1536]); // Vector search. var searchResults = vectorSearch.SearchAsync(VectorSearchQuery.CreateQuery(searchEmbedding)); searchResults = vectorSearch.SearchAsync(searchEmbedding); // Extension method. // Vector search with specific vector field. searchResults = vectorSearch.SearchAsync(VectorSearchQuery.CreateQuery(searchEmbedding, new() { VectorFieldName = nameof(Glossary.DefinitionEmbedding) })); searchResults = vectorSearch.SearchAsync(searchEmbedding, new() { VectorFieldName = nameof(Glossary.DefinitionEmbedding) }); // Extension method. // Text vector search. searchResults = vectorSearch.SearchAsync(VectorSearchQuery.CreateQuery("What does Semantic Kernel mean?")); searchResults = vectorSearch.SearchAsync("What does Semantic Kernel mean?"); // Extension method. // Text vector search with specific vector field. searchResults = vectorSearch.SearchAsync(VectorSearchQuery.CreateQuery("What does Semantic Kernel mean?", new() { VectorFieldName = nameof(Glossary.DefinitionEmbedding) })); searchResults = vectorSearch.SearchAsync("What does Semantic Kernel mean?", new() { VectorFieldName = nameof(Glossary.DefinitionEmbedding) }); // Extension method. // Hybrid vector search. searchResults = vectorSearch.SearchAsync(VectorSearchQuery.CreateHybridQuery(searchEmbedding, "What does Semantic Kernel mean?", new() { HybridFieldName = nameof(Glossary.Definition) })); searchResults = vectorSearch.HybridVectorizedTextSearchAsync(searchEmbedding, "What does Semantic Kernel mean?", new() { HybridFieldName = nameof(Glossary.Definition) }); // Extension method. // Hybrid text vector search with field names specified for both vector and keyword search. searchResults = vectorSearch.SearchAsync(VectorSearchQuery.CreateHybridQuery("What does Semantic Kernel mean?", new() { VectorFieldName = nameof(Glossary.DefinitionEmbedding), HybridFieldName = nameof(Glossary.Definition) })); searchResults = vectorSearch.HybridVectorizableTextSearchAsync("What does Semantic Kernel mean?", new() { VectorFieldName = nameof(Glossary.DefinitionEmbedding), HybridFieldName = nameof(Glossary.Definition) }); // Extension method. // In future we can also support images or other modalities, e.g. IVectorSearch imageVectorSearch = ... searchResults = imageVectorSearch.SearchAsync(VectorSearchQuery.CreateBase64EncodedImageQuery(base64EncodedImageString, new() { VectorFieldName = nameof(Images.ImageEmbedding) })); // Vector search with filtering. var filter = new BasicVectorSearchFilter().EqualTo(nameof(Glossary.Category), "Core Definitions"); searchResults = vectorSearch.SearchAsync( VectorSearchQuery.CreateQuery( searchEmbedding, new() { Filter = filter, VectorFieldName = nameof(Glossary.DefinitionEmbedding) })); } ``` ## Options considered ### Option 1: Search object See the [Interface](#interface) section above for a description of this option. Pros: - It can support multiple query types, each with different options. - It is easy to add more query types in future without it being a breaking change. Cons: - Any query type that isn't supported by a connector implementation will cause an exception to be thrown. ### Option 2: Vector only The abstraction will only support the most basic functionality and all other functionality is supported on the concrete implementation. E.g. Some vector databases do not support generating embeddings in the service, so the connector would not support `VectorizableTextSearchQuery` from option 1. Pros: - The user doesn't need to know which query types are supported by which vector store connector types. Cons: - Only allows searching by vectors in the abstraction which is a very low common denominator. ```csharp interface IVectorSearch { IAsyncEnumerable> SearchAsync( TVector vector, VectorSearchOptions? searchOptions CancellationToken cancellationToken = default); } class AzureAISearchVectorStoreRecordCollection : IVectorSearch { public IAsyncEnumerable> SearchAsync( TVector vector, VectorSearchOptions? searchOptions CancellationToken cancellationToken = default); public IAsyncEnumerable> SearchAsync( string queryText, VectorSearchOptions? searchOptions CancellationToken cancellationToken = default); } ``` ### Option 3: Abstract base class One of the main requirements is to allow future extensibility with additional query types. One way to achieve this is to use an abstract base class that can auto implement new methods that throw with NotSupported unless overridden by each implementation. This behavior would be similar to Option 1. With Option 1 though, the same behavior is achieved via extension methods. The set of methods end up being the same with Option 1 and Option 3, except that Option 1 also has a Search method that takes `VectorSearchQuery` as input. `IVectorSearch` is a separate interface to `IVectorStoreRecordCollection`, but the intention is for `IVectorStoreRecordCollection` to inherit from `IVectorSearch`. This means that some (most) implementations of `IVectorSearch` will be part of `IVectorStoreRecordCollection` implementations. We anticipate cases where we need to support standalone `IVectorSearch` implementations where the store supports search but isn't necessarily writable. Therefore a hierarchy of abstract base classes would be required. We also considered default interface methods, but there is no support in .net Framework for this, and SK has to support .net Framework. Pros: - It can support multiple query types, each with different options. - It is easy to add more query types in future without it being a breaking change. - Allows different return types for each search type. Cons: - Any query type that isn't supported by a connector implementation will cause an exception to be thrown. - Doesn't support multiple inheritance, so where multiple key types need to be supported this doesn't work. - Doesn't support multiple inheritance, so any additional functionality that needs to be added to `VectorStoreRecordCollection`, won't be possible to be added using a similar mechanism. ```csharp abstract class BaseVectorSearch where TRecord : class { public virtual IAsyncEnumerable> SearchAsync( this IVectorSearch search, TVector vector, VectorSearchOptions? options = default, CancellationToken cancellationToken = default) { throw new NotSupportedException($"Vectorized search is not supported by the {this._connectorName} connector"); } public virtual IAsyncEnumerable> SearchAsync( this IVectorSearch search, string searchText, VectorSearchOptions? options = default, CancellationToken cancellationToken = default) { throw new NotSupportedException($"Vectorizable text search is not supported by the {this._connectorName} connector"); } } abstract class BaseVectorStoreRecordCollection : BaseVectorSearch { public virtual async Task CreateCollectionIfNotExistsAsync(CancellationToken cancellationToken = default) { if (!await this.CollectionExistsAsync(cancellationToken).ConfigureAwait(false)) { await this.CreateCollectionAsync(cancellationToken).ConfigureAwait(false); } } } // We support multiple types of keys here, but we cannot inherit from multiple base classes. class QdrantVectorStoreRecordCollection : BaseVectorStoreRecordCollection : BaseVectorStoreRecordCollection { } ``` ### Option 4: Interface per search type One of the main requirements is to allow future extensibility with additional query types. One way to achieve this is to add additional interfaces as implementations support additional functionality. Pros: - Allows different implementations to support different search types without needing to throw exceptions for not supported functionality. - Allows different return types for each search type. Cons: - Users will still need to know which interfaces are implemented by each implementation to cast to those as necessary. - We will not be able to add more Search functionality to `IVectorStoreRecordCollection` over time, since it would be a breaking change. Therefore, a user that has an instance of `IVectorStoreRecordCollection`, but wants to e.g. do a hybrid search, will need to cast to `IHybridTextVectorizedSearch` first before being able to search. ```csharp // Vector search using vector. interface IVectorizedSearch { IAsyncEnumerable> SearchAsync( TVector vector, VectorSearchOptions? searchOptions); } // Vector search using query text that will be vectorized downstream. interface IVectorizableTextSearch { IAsyncEnumerable> SearchAsync( string queryText, VectorSearchOptions? searchOptions); } // Hybrid search using a vector and a text portion that will be used for a keyword search. interface IHybridTextVectorizedSearch { IAsyncEnumerable> SearchAsync( TVector vector, string queryText, HybridVectorSearchOptions? searchOptions); } // Hybrid search using text that will be vectorized downstream and also used for a keyword search. interface IHybridVectorizableTextSearch { IAsyncEnumerable> SearchAsync( string queryText, HybridVectorSearchOptions? searchOptions); } class AzureAISearchVectorStoreRecordCollection: IVectorStoreRecordCollection, IVectorizedSearch, IVectorizableTextSearch { } ``` ## Decision Outcome Chosen option: 4 The consensus is that option 4 is easier to understand for users, where only functionality that works for all vector stores are exposed by default. ================================================ FILE: docs/decisions/0059-text-search.md ================================================ --- # These are optional elements.

There are two sets of abstractions and plugins depending on whether the developer wants to perform search against a Vector database or a Web search engine. The current abstractions are experimental and the purpose of this ADR is to progress the design of the abstractions so that they can graduate to non experimental status. There are two main use cases we need to support: 1. Enable Prompt Engineers to easily insert grounding information in prompts i.e. support for Retrieval-Augmented Generation scenarios. 2. Enable Developers to register search plugins which can be called by the LLM to retrieve additional data it needs to respond to a user ask i.e. support for Function Calling scenarios. What both of these scenarios have in common is that we need to generate a `KernelPlugin` from a search service and register it for use with the `Kernel`. ### Retrieval-Augmented Generation Scenarios Retrieval-Augmented Generation (RAG) is a process of optimizing the output of an LLM, so it references authoritative data which may not be part of its training data when generating a response. This reduce the likelihood of hallucinations and also enables the provision of citations which the end user can use to independently verify the response from the LLM. RAG works by retrieving additional data that is relevant to the use query and then augment the prompt with this data before sending to the LLM. Consider the following sample where the top Bing search results are included as additional data in the prompt. ```csharp // Create a kernel with OpenAI chat completion IKernelBuilder kernelBuilder = Kernel.CreateBuilder(); kernelBuilder.AddOpenAIChatCompletion( modelId: TestConfiguration.OpenAI.ChatModelId, apiKey: TestConfiguration.OpenAI.ApiKey, httpClient: httpClient); Kernel kernel = kernelBuilder.Build(); // Create a text search using the Bing search service var textSearch = new BingTextSearch(new(TestConfiguration.Bing.ApiKey)); // Build a text search plugin with Bing search service and add to the kernel var searchPlugin = textSearch.CreateKernelPluginWithTextSearch("SearchPlugin"); kernel.Plugins.Add(searchPlugin); // Invoke prompt and use text search plugin to provide grounding information var query = "What is the Semantic Kernel?"; KernelArguments arguments = new() { { "query", query } }; Console.WriteLine(await kernel.InvokePromptAsync("{{SearchPlugin.Search $query}}. {{$query}}", arguments)); ``` This example works as follows: 1. Create a `BingTextSearch` which can perform Bing search queries. 2. Wrap the `BingTextSearch` as a plugin which can be called when rendering a prompt. 3. Insert a call to the plugin which performs a search using the user query. 4. The prompt will be augmented with the abstract from the top search results. **Note:** In this case the abstract from the search result is the only data included in the prompt. The LLM should use this data if it considers it relevant but there is no feedback mechanism to the user which would allow them to verify the source of the data. The following sample shows a solution to this problem. ```csharp // Create a kernel with OpenAI chat completion IKernelBuilder kernelBuilder = Kernel.CreateBuilder(); kernelBuilder.AddOpenAIChatCompletion( modelId: TestConfiguration.OpenAI.ChatModelId, apiKey: TestConfiguration.OpenAI.ApiKey, httpClient: httpClient); Kernel kernel = kernelBuilder.Build(); // Create a text search using the Bing search service var textSearch = new BingTextSearch(new(TestConfiguration.Bing.ApiKey)); // Build a text search plugin with Bing search service and add to the kernel var searchPlugin = textSearch.CreateKernelPluginWithGetSearchResults("SearchPlugin"); kernel.Plugins.Add(searchPlugin); // Invoke prompt and use text search plugin to provide grounding information var query = "What is the Semantic Kernel?"; string promptTemplate = @" {{#with (SearchPlugin-GetSearchResults query)}} {{#each this}} Name: {{Name}} Value: {{Value}} Link: {{Link}} ----------------- {{/each}} {{/with}} {{query}} Include citations to the relevant information where it is referenced in the response. "; KernelArguments arguments = new() { { "query", query } }; HandlebarsPromptTemplateFactory promptTemplateFactory = new(); Console.WriteLine(await kernel.InvokePromptAsync( promptTemplate, arguments, templateFormat: HandlebarsPromptTemplateFactory.HandlebarsTemplateFormat, promptTemplateFactory: promptTemplateFactory )); ``` This example works as follows: 1. Create a `BingTextSearch` which can perform Bing search queries and convert the response into a normalized format. 2. The normalized format is a Semantic Kernel abstraction called `TextSearchResult` which includes a name, value and link for each search result. 3. Wrap the `BingTextSearch` as a plugin which can be called when rendering a prompt. 4. Insert a call to the plugin which performs a search using the user query. 5. The prompt will be augmented with the name, value and link from the top search results. 6. The prompt also instructs the LLM to include citations to the relevant information in the response. An example response would look like this: ``` The Semantic Kernel (SK) is a lightweight and powerful SDK developed by Microsoft that integrates Large Language Models (LLMs) such as OpenAI, Azure OpenAI, and Hugging Face with traditional programming languages like C#, Python, and Java ([GitHub](https://github.com/microsoft/semantic-kernel)). It facilitates the combination of natural language processing capabilities with pre-existing APIs and code, enabling developers to add large language capabilities to their applications swiftly ([What It Is and Why It Matters](https://techcommunity.microsoft.com/t5/microsoft-developer-community/semantic-kernel-what-it-is-and-why-it-matters/ba-p/3877022)). The Semantic Kernel serves as a middleware that translates the AI model's requests into function calls, effectively bridging the gap between semantic functions (LLM tasks) and native functions (traditional computer code) ([InfoWorld](https://www.infoworld.com/article/2338321/semantic-kernel-a-bridge-between-large-language-models-and-your-code.html)). It also enables the automatic orchestration and execution of tasks using natural language prompting across multiple languages and platforms ([Hello, Semantic Kernel!](https://devblogs.microsoft.com/semantic-kernel/hello-world/)). In addition to its core capabilities, Semantic Kernel supports advanced functionalities like prompt templating, chaining, and planning, which allow developers to create intricate workflows tailored to specific use cases ([Architecting AI Apps](https://devblogs.microsoft.com/semantic-kernel/architecting-ai-apps-with-semantic-kernel/)). By describing your existing code to the AI models, Semantic Kernel effectively marshals the request to the appropriate function, returns results back to the LLM, and enables the AI agent to generate a final response ([Quickly Start](https://learn.microsoft.com/en-us/semantic-kernel/get-started/quick-start-guide)). This process brings unparalleled productivity and new experiences to application users ([Hello, Semantic Kernel!](https://devblogs.microsoft.com/semantic-kernel/hello-world/)). The Semantic Kernel is an indispensable tool for developers aiming to build advanced AI applications by seamlessly integrating large language models with traditional programming frameworks ([Comprehensive Guide](https://gregdziedzic.com/understanding-semantic-kernel-a-comprehensive-guide/)). ``` **Note:** In this case there is a link to the relevant information so the end user can follow the links to verify the response. The next sample shows an alternative solution that uses Bing Text Search and the built-in result type. ```csharp // Create a kernel with OpenAI chat completion IKernelBuilder kernelBuilder = Kernel.CreateBuilder(); kernelBuilder.AddOpenAIChatCompletion( modelId: TestConfiguration.OpenAI.ChatModelId, apiKey: TestConfiguration.OpenAI.ApiKey, httpClient: httpClient); Kernel kernel = kernelBuilder.Build(); // Create a text search using the Bing search service var textSearch = new BingTextSearch(new(TestConfiguration.Bing.ApiKey)); // Build a text search plugin with Bing search service and add to the kernel var searchPlugin = textSearch.CreateKernelPluginWithGetBingWebPages("SearchPlugin"); kernel.Plugins.Add(searchPlugin); // Invoke prompt and use text search plugin to provide grounding information var query = "What is the Semantic Kernel?"; string promptTemplate = @" {{#with (SearchPlugin-GetBingWebPages query)}} {{#each this}} Name: {{Name}} Snippet: {{Snippet}} Link: {{DisplayUrl}} Date Last Crawled: {{DateLastCrawled}} ----------------- {{/each}} {{/with}} {{query}} Include citations to and the date of the relevant information where it is referenced in the response. "; KernelArguments arguments = new() { { "query", query } }; HandlebarsPromptTemplateFactory promptTemplateFactory = new(); Console.WriteLine(await kernel.InvokePromptAsync( promptTemplate, arguments, templateFormat: HandlebarsPromptTemplateFactory.HandlebarsTemplateFormat, promptTemplateFactory: promptTemplateFactory )); ``` This example works as follows: 1. Create a `BingTextSearch` which can perform Bing search queries. 2. The default format is a Bing specific class called `BingWebPage` which includes a name, snippet, display url and date last crawled for each search result. 3. Wrap the `BingTextSearch` as a plugin which can be called when rendering a prompt. 4. Insert a call to the plugin which performs a search using the user query. 5. The prompt will be augmented with the name, snippet, display url and date last crawled from the top search results. 6. The prompt also instructs the LLM to include citations to and date of the relevant information in the response. An example response would look like this: ``` Semantic Kernel is an open-source development kit designed to facilitate the integration of advanced AI models into existing C#, Python, or Java codebases. It serves as an efficient middleware that enables rapid delivery of enterprise-grade AI solutions (Microsoft Learn, 2024-08-14). One of the standout features of Semantic Kernel is its lightweight SDK, which allows developers to blend conventional programming languages with Large Language Model (LLM) AI capabilities through prompt templating, chaining, and planning (Semantic Kernel Blog, 2024-08-10). This AI SDK uses natural language prompting to create and execute semantic AI tasks across multiple languages and platforms, offering developers a simple yet powerful programming model to add large language capabilities to their applications in a matter of minutes (Microsoft Developer Community, 2024-08-13). Semantic Kernel also leverages function calling—a native feature of most LLMs—enabling the models to request specific functions to fulfill user requests, thereby streamlining the planning process (Microsoft Learn, 2024-08-14). The toolkit is versatile and extends support to multiple programming environments. For instance, Semantic Kernel for Java is compatible with Java 8 and above, making it accessible to a wide range of Java developers (Semantic Kernel Blog, 2024-08-14). Additionally, Sketching an architecture with Semantic Kernel can simplify business automation using models from platforms such as OpenAI, Azure OpenAI, and Hugging Face (Semantic Kernel Blog, 2024-08-14). For .NET developers, Semantic Kernel is highly recommended for working with AI in .NET applications, offering a comprehensive guide on incorporating Semantic Kernel into projects and understanding its core concepts (Microsoft Learn, 2024-08-14). Last but not least, Semantic Kernel has an extension for Visual Studio Code that facilitates the design and testing of semantic functions, enabling developers to efficiently integrate and test AI models with their existing data (GitHub, 2024-08-14).

The url to the full page content is also available so the full page could be downloaded and used. There may be other search implementations that don't include any relevant information and just include a link, this next examples shows how to handle this case. ```csharp // Build a text search plugin with Bing search service and add to the kernel var searchPlugin = KernelPluginFactory.CreateFromFunctions("SearchPlugin", null, [CreateGetFullWebPages(textSearch)]); kernel.Plugins.Add(searchPlugin); // Invoke prompt and use text search plugin to provide grounding information var query = "What is the Semantic Kernel?"; string promptTemplate = @" {{#with (SearchPlugin-GetFullWebPages query)}} {{#each this}} Name: {{Name}} Value: {{Value}} Link: {{Link}} ----------------- {{/each}} {{/with}} {{query}} Include citations to the relevant information where it is referenced in the response. "; KernelArguments arguments = new() { { "query", query } }; HandlebarsPromptTemplateFactory promptTemplateFactory = new(); Console.WriteLine(await kernel.InvokePromptAsync( promptTemplate, arguments, templateFormat: HandlebarsPromptTemplateFactory.HandlebarsTemplateFormat, promptTemplateFactory: promptTemplateFactory )); ``` In this sample we call `BingSearchExample.CreateGetFullWebPagesOptions(textSearch)` to create the options that define the search plugin. The code for this method looks like this: ```csharp private static KernelFunction CreateGetFullWebPages(ITextSearch textSearch, BasicFilterOptions? basicFilter = null) { async Task> GetFullWebPagesAsync(Kernel kernel, KernelFunction function, KernelArguments arguments, CancellationToken cancellationToken) { arguments.TryGetValue("query", out var query); if (string.IsNullOrEmpty(query?.ToString())) { return []; } var parameters = function.Metadata.Parameters; arguments.TryGetValue("count", out var count); arguments.TryGetValue("skip", out var skip); SearchOptions searchOptions = new() { Count = (count as int?) ?? 2, Offset = (skip as int?) ?? 0, BasicFilter = basicFilter }; var result = await textSearch.SearchAsync(query.ToString()!, searchOptions, cancellationToken).ConfigureAwait(false); var resultList = new List(); using HttpClient client = new(); await foreach (var item in result.Results.WithCancellation(cancellationToken).ConfigureAwait(false)) { string? value = item.Snippet; try { if (item.Url is not null) { value = await client.GetStringAsync(new Uri(item.Url), cancellationToken); value = ConvertHtmlToPlainText(value); } } catch (HttpRequestException) { } resultList.Add(new() { Name = item.Name, Value = value, Link = item.Url }); } return resultList; } var options = new KernelFunctionFromMethodOptions() { FunctionName = "GetFullWebPages", Description = "Perform a search for content related to the specified query. The search will return the name, full web page content and link for the related content.", Parameters = [ new KernelParameterMetadata("query") { Description = "What to search for", IsRequired = true }, new KernelParameterMetadata("count") { Description = "Number of results", IsRequired = false, DefaultValue = 2 }, new KernelParameterMetadata("skip") { Description = "Number of results to skip", IsRequired = false, DefaultValue = 0 }, ], ReturnParameter = new() { ParameterType = typeof(KernelSearchResults) }, }; return KernelFunctionFactory.CreateFromMethod(GetFullWebPagesAsync, options); } ``` The custom `CreateGetFullWebPages` will result in a search plugin with a single function called `GetFullWebPages`, this method works as follows: 1. It uses the `BingTextSearch` instances for retrieve the top pages for the specified query. 2. For each web page is reads the full HTML content using the url and then converts in to a plain text representation. Here's an example of what the response will look like: ``` The Semantic Kernel (SK) is an open-source development kit from Microsoft designed to facilitate the integration of large language models (LLMs) into AI applications. It acts as middleware, enabling the rapid development of enterprise-grade solutions by providing a flexible, modular, and extensible programming model that supports multiple languages like C#, Python, and Java [^1^][^4^]. ### Key Features: 1. **AI Service Integration**: - The Semantic Kernel supports popular AI models from providers like OpenAI, Azure OpenAI, and Hugging Face.

In the above example the total token count is `26836` compared to `1081` if snippets of the web page are used. ### Function Calling Scenarios Function calling allows you to connect LLMs to external tools and systems. This capability can be used to enable an LLM to retrieve relevant information it needs in order to return a response to a user query. In the context of this discussion we want to allow an LLM to perform a search to return relevant information. We also want to enable developers to easily customize the search operations to improve the LLMs ability to retrieve the most relevant information. We need to support the following use cases: 1. Enable developers to adapt an arbitrary text search implementation to be a search plugin which can be called by an LLM to perform searches. - Search results can be returned as text, or in a normalized format, or is a proprietary format associated with the text search implementation. 1. Enable developers to easily customize the search plugin, typical customizations will include: - Alter the search function metadata i.e. name, description, parameter details - Alter which search function(s) are included in the plugin - Alter the search function(s) behavior Consider the following sample where the LLM can call Bing search to help it respond to the user ask. ```csharp // Create a kernel with OpenAI chat completion IKernelBuilder kernelBuilder = Kernel.CreateBuilder(); kernelBuilder.AddOpenAIChatCompletion( modelId: TestConfiguration.OpenAI.ChatModelId, apiKey: TestConfiguration.OpenAI.ApiKey, httpClient: httpClient); Kernel kernel = kernelBuilder.Build(); // Create a search service with Bing search service var textSearch = new BingTextSearch(new(TestConfiguration.Bing.ApiKey)); // Build a text search plugin with Bing search service and add to the kernel var searchPlugin = textSearch.CreateKernelPluginWithTextSearch("SearchPlugin"); kernel.Plugins.Add(searchPlugin); // Invoke prompt and use text search plugin to provide grounding information OpenAIPromptExecutionSettings settings = new() { ToolCallBehavior = ToolCallBehavior.AutoInvokeKernelFunctions }; KernelArguments arguments = new(settings); Console.WriteLine(await kernel.InvokePromptAsync("What is the Semantic Kernel?", arguments)); ``` This example works as follows: 1. Create a BingTextSearch which can perform Bing search queries. 1. Wrap the BingTextSearch as a plugin which can be advertised to the LLM. 1. Enable automatic function calling, which allows the LLM to call Bing search to retrieve relevant information. **Note:** The `TextSearchKernelPluginFactory.CreateFromTextSearch` factory method is used to create the search plugin. This method will create a plugin with a `Search` function which returns the search results as a collection of `string` instances. An example response would look like this: ``` The Semantic Kernel is an open-source development kit aimed at integrating the latest AI models into various programming languages, such as C#, Python, or Java. It serves as a middleware enabling rapid delivery of enterprise-grade AI solutions. Key features and capabilities of the Semantic Kernel include: 1. **Function Call Planning**: It leverages function calling—a native feature of most large language models (LLMs)—to allow these models to request specific functions to satisfy user requests. 2. **Semantic Function Design**: The Semantic Kernel extension for Visual Studio Code simplifies the design and testing of semantic functions, providing an interface for creating and evaluating these functions with existing models and data. 3. **Programming Model**: It introduces a programming model that combines conventional programming languages with AI "prompts" through prompt templating, chaining, and planning capabilities. 4. **Multi-Language Support**: Compatible with programming in languages like C#, Python, and Java, ensuring broad accessibility and flexibility. 5. **AI Agent Creation**: Facilitates building AI agents that can call existing code, thus automating business processes using models from OpenAI, Azure OpenAI, Hugging Face, and more. The Semantic Kernel helps developers quickly add large language capabilities to their applications, allowing the creation of smart, adaptable systems that can naturally interact with human users. ``` **Note:** In this case the abstract from the search result is the only data included in the prompt. The LLM should use this data if it considers it relevant but there is no feedback mechanism to the user which would allow them to verify the source of the data. The following sample shows a solution to this problem. ```csharp // Create a kernel with OpenAI chat completion IKernelBuilder kernelBuilder = Kernel.CreateBuilder(); kernelBuilder.AddOpenAIChatCompletion( modelId: TestConfiguration.OpenAI.ChatModelId, apiKey: TestConfiguration.OpenAI.ApiKey, httpClient: httpClient); Kernel kernel = kernelBuilder.Build(); // Create a search service with Bing search service var textSearch = new BingTextSearch(new(TestConfiguration.Bing.ApiKey)); // Build a text search plugin with Bing search service and add to the kernel var searchPlugin = textSearch.CreateKernelPluginWithGetSearchResults("SearchPlugin"); kernel.Plugins.Add(searchPlugin); // Invoke prompt and use text search plugin to provide grounding information OpenAIPromptExecutionSettings settings = new() { ToolCallBehavior = ToolCallBehavior.AutoInvokeKernelFunctions }; KernelArguments arguments = new(settings); Console.WriteLine(await kernel.InvokePromptAsync("What is the Semantic Kernel? Include citations to the relevant information where it is referenced in the response.", arguments)); ``` There is just one change in the sample, the plugin is created using the `TextSearchKernelPluginFactory.CreateFromTextSearchResults` factory method. This method will create a plugin with a `Search` function which returns a collection of `TextSearchResult` instances which in turn will contain a link which can be used to provide a citation. An example response would look like this: ``` The Semantic Kernel is an open-source software development kit (SDK) that facilitates the integration of advanced AI models into applications. It allows developers to harness the power of large language models (LLMs) for building innovative AI solutions. Semantic Kernel supports C#, Python, and Java, and it emphasizes security, modularity, and flexibility, making it suitable for enterprise-grade applications. Key Features: 1. **Integration of AI Models**: Semantic Kernel enables developers to incorporate AI models from platforms such as OpenAI and Hugging Face into their codebase. This allows for creating powerful AI agents that can automate a variety of tasks. 2. **Semantic Functions**: The SDK provides tools to design and test semantic functions. These functions facilitate natural language processing capabilities in applications, allowing for more intuitive user interactions ([GitHub - microsoft/semantic-kernel](https://github.com/microsoft/semantic-kernel)). 3. **Comprehensive Documentation and Guides**: Detailed guides and documentation are available to help developers get started quickly. They cover everything from installing the SDK to building AI agents and creating robust AI solutions ([Introduction to Semantic Kernel | Microsoft Learn](https://learn.microsoft.com/en-us/semantic-kernel/overview/), [How to quickly start with Semantic Kernel | Microsoft Learn](https://learn.microsoft.com/en-us/semantic-kernel/get-started/quick-start-guide)). 4. **Support for Enterprise Applications**: The kernel is designed to provide enterprise-grade services and plugins, ensuring scalability and robustness for large and complex applications ([Architecting AI Apps with Semantic Kernel | Semantic Kernel](https://devblogs.microsoft.com/semantic-kernel/architecting-ai-apps-with-semantic-kernel/)). 5. **Integration with Popular Tools**: Semantic Kernel can be seamlessly integrated with conventional programming languages and popular development environments, providing tools to extend functionalities with minimal effort ([GitHub - microsoft/semantic-kernel](https://github.com/microsoft/semantic-kernel)). For more detailed information, the following sources can be referenced: - [Introduction to Semantic Kernel | Microsoft Learn](https://learn.microsoft.com/en-us/semantic-kernel/overview/) - [Semantic Kernel documentation | Microsoft Learn](https://learn.microsoft.com/en-us/semantic-kernel/) - [GitHub - microsoft/semantic-kernel](https://github.com/microsoft/semantic-kernel) These resources offer comprehensive insights into using the Semantic Kernel to leverage AI technology effectively in software development. ``` The next sample shows how a developer can customize the configuration of the search plugin. ```csharp // Create a kernel with OpenAI chat completion IKernelBuilder kernelBuilder = Kernel.CreateBuilder(); kernelBuilder.AddOpenAIChatCompletion( modelId: TestConfiguration.OpenAI.ChatModelId, apiKey: TestConfiguration.OpenAI.ApiKey, httpClient: httpClient); Kernel kernel = kernelBuilder.Build(); // Create a search service with Bing search service var textSearch = new BingTextSearch(new(TestConfiguration.Bing.ApiKey)); // Build a text search plugin with Bing search service and add to the kernel var basicFilter = new BasicFilterOptions().Equality("site", "devblogs.microsoft.com"); var searchPlugin = KernelPluginFactory.CreateFromFunctions("SearchPlugin", "Search Microsoft Dev Blogs site", [textSearch.CreateGetSearchResults(basicFilter)]); kernel.Plugins.Add(searchPlugin); // Invoke prompt and use text search plugin to provide grounding information OpenAIPromptExecutionSettings settings = new() { ToolCallBehavior = ToolCallBehavior.AutoInvokeKernelFunctions }; KernelArguments arguments = new(settings); Console.WriteLine(await kernel.InvokePromptAsync("What is the Semantic Kernel? Include citations to the relevant information where it is referenced in the response.", arguments)); ``` This sample provides a description for the search plugin i.e., in this case we only want to search the Microsoft Developer Blogs site and also the options for creating the plugin. The options allow the search plugin function definition(s) to be specified i.e., in this case we want to use a default search function that includes a basic filter which specifies the only site to include is `devblogs.microsoft.com`. An example response would look like this and you will note that all of the citations are from `devblogs.microsoft.com`: ``` The Semantic Kernel (SK) is a lightweight Software Development Kit (SDK) that facilitates the integration of conventional programming languages like C# and Python with the latest advancements in Large Language Models (LLM) AI, such as prompt templating, chaining, and planning capabilities. It enables the building of AI solutions that can leverage models from platforms like OpenAI, Azure OpenAI, and Hugging Face ([Hello, Semantic Kernel!](https://devblogs.microsoft.com/semantic-kernel/hello-world/)). Semantic Kernel is incredibly versatile, allowing developers to create advanced AI applications by incorporating AI agents into their applications. These agents can interact with code, automate business processes, and manage multiple LLMs with ease. The framework also supports pre-built features like planners to simplify orchestration and is fully compatible with .NET Dependency Injection abstractions ([Build AI Applications with ease using Semantic Kernel](https://devblogs.microsoft.com/semantic-kernel/build-ai-applications-with-ease-using-semantic-kernel-and-net-aspire/), [How to Get Started using Semantic Kernel .NET](https://devblogs.microsoft.com/semantic-kernel/how-to-get-started-using-semantic-kernel-net/)). For more information and the latest updates from the Semantic Kernel team, you can visit their [official blog](https://devblogs.microsoft.com/semantic-kernel/). ``` In the previous example the site has hard coded. It is also possible to allow the LLM to extract the site from the user query. In the example below a custom search function is created which includes an additional argument to allow the LLM to set the site. ```csharp // Create a kernel with OpenAI chat completion IKernelBuilder kernelBuilder = Kernel.CreateBuilder(); kernelBuilder.AddOpenAIChatCompletion( modelId: TestConfiguration.OpenAI.ChatModelId, apiKey: TestConfiguration.OpenAI.ApiKey, httpClient: httpClient); Kernel kernel = kernelBuilder.Build(); // Create a search service with Bing search service var textSearch = new BingTextSearch(new(TestConfiguration.Bing.ApiKey)); // Build a text search plugin with Bing search service and add to the kernel var searchPlugin = KernelPluginFactory.CreateFromFunctions("SearchPlugin", "Search Microsoft Dev Blogs site", [CreateSearchBySite(textSearch)]); kernel.Plugins.Add(searchPlugin); // Invoke prompt and use text search plugin to provide grounding information OpenAIPromptExecutionSettings settings = new() { ToolCallBehavior = ToolCallBehavior.AutoInvokeKernelFunctions }; KernelArguments arguments = new(settings); Console.WriteLine(await kernel.InvokePromptAsync("What is the Semantic Kernel? Only include results from devblogs.microsoft.com. Include citations to the relevant information where it is referenced in the response.", arguments)); ``` The code below shows how the custom search function is created. - The `KernelFunction` includes an additional optional parameter called `site` - If the `site` parameter is provided a `BasicFilterOptions` instance is created which will cause Bing to return responses only from that site - A custom function description and parameter description are provided to help the LLM in using this method. ```csharp private static KernelFunction CreateSearchBySite(ITextSearch textSearch, BasicFilterOptions? basicFilter = null, MapSearchResultToString? mapToString = null) { async Task> SearchAsync(Kernel kernel, KernelFunction function, KernelArguments arguments, CancellationToken cancellationToken) { arguments.TryGetValue("query", out var query); if (string.IsNullOrEmpty(query?.ToString())) { return []; } var parameters = function.Metadata.Parameters; arguments.TryGetValue("count", out var count); arguments.TryGetValue("skip", out var skip); arguments.TryGetValue("site", out var site); BasicFilterOptions? basicFilter = null; if (string.IsNullOrEmpty(site?.ToString())) { basicFilter = new BasicFilterOptions().Equality("site", site?.ToString()!); } SearchOptions searchOptions = new() { Count = (count as int?) ?? 2, Offset = (skip as int?) ?? 0, BasicFilter = basicFilter }; var result = await textSearch.SearchAsync(query?.ToString()!, searchOptions, cancellationToken).ConfigureAwait(false); return await result.Results.ToListAsync(cancellationToken).ConfigureAwait(false); } var options = new KernelFunctionFromMethodOptions() { FunctionName = "Search", Description = "Perform a search for content related to the specified query and optionally from the specified domain.", Parameters = [ new KernelParameterMetadata("query") { Description = "What to search for", IsRequired = true }, new KernelParameterMetadata("count") { Description = "Number of results", IsRequired = false, DefaultValue = 2 }, new KernelParameterMetadata("skip") { Description = "Number of results to skip", IsRequired = false, DefaultValue = 0 }, new KernelParameterMetadata("site") { Description = "Only return results from this domain", IsRequired = false, DefaultValue = 2 }, ], ReturnParameter = new() { ParameterType = typeof(KernelSearchResults) }, }; return KernelFunctionFactory.CreateFromMethod(SearchAsync, options); } ``` ## Decision Drivers - An AI must be able to perform searches with a search plugin and get back results with the following types: 1. Simple string value. 2. Normalized value including a name, content and link. 3. Data model supported by the underlying search implementation. - Application developers should be able to easily add a search plugin using a search connector with minimal lines of code (ideally one). - Application developers must be able to provide connector specific settings. - Application developers must be able to set required information e.g. `IndexName` for search providers. - Application developers must be able to support custom schemas for search connectors. No fields should be required. - Community developers must be able to easily create a new search connector. - Community developers must be able to easily create a new search connector return type that inherits from `KernelSearchResults` (alternate suggestion `SearchResultContent`). - The design must be flexible to support future requirements and different search modalities. - Application developers must to be able to override the semantic descriptions of the search function(s) per instance registered via settings / inputs. - Search service developers must be able to define the attributes of the search method (e.g., name, description, input names, input descriptions, return description). Expect these to be handled by Vector search - Application developers must be able to optionally define the execution settings of an embedding service with a default being provided by the Kernel. - Application developers must be ab able to import a vector DB search connection using an ML index file. ### Future Requirements - An AI can perform search with filters using a search plugin. This will require a Connector Dev to implement a search interface that accepts a Filter object. - Connector developers can decide which search filters are given to the AI by “default”. - Application developers can override which filters the AI can use via search settings. - Application developers can set the filters when they create the connection. ### Search Abstractions The diagram below shows the layering in the proposed design. From the bottom up these are: - We aim to support an arbitrary search service, which could be a Web search, Vector DB search or a proprietary implementation. - There will be a client API layer. Note we are **not** trying to provide a search abstraction to normalize this layer. - We are defining an `IVectorSearch` abstraction which will allow us to perform searches against multiple Vector databases. This will be covered in a separate ADR. - The focus for this ADR is the `ITextSearch` abstraction which is being designed to support the use cases described earlier in this document. - We will provide a number of implementations of the `ITextSearch` abstraction e.g., Bing, Google, Vector DB's. The final list is TBD. Search Abstractions ## Considered Options 1. Define `ITextSearch` abstraction with single `Search` method and implementations check type 2. Define `ITextSearch` abstraction with single `Search` method and implementations implement what they support 3. Define `ITextSearch` abstraction with multiple search methods 4. Define `ITextSearch` abstraction with multiple search methods and additional methods on implementations 5. Define `ITextSearch` and `ITextSearch` abstractions ## Decision Outcome Chosen option: "Define `ITextSearch` abstraction with multiple search methods and additional methods on implementations", because it meets the requirements, allows for type safe methods, can support arbitrary object responses and simplifies the implementation burden for developers implementing the abstraction. ## Pros and Cons of the Options ### 1. Define `ITextSearch` abstraction with single `Search` method and implementations check type Abstraction would look like this: ```csharp public interface ITextSearch where T : class { public Task> SearchAsync(string query, SearchOptions? searchOptions = null, CancellationToken cancellationToken = default); } ``` Implementation would look like this: ```csharp public class BingTextSearch : ITextSearch where T : class { public async Task> SearchAsync(string query, SearchOptions? searchOptions = null, CancellationToken cancellationToken = default) { // Retrieve Bing search results if (typeof(T) == typeof(string)) { // Convert to string (custom mapper is supported) } else if (typeof(T) == typeof(TextSearchResult)) { // Convert to TextSearchResult (custom mapper is supported) } else if (typeof(T) == typeof(BingWebPage)) { // Return Bing search results } } } ``` **Note:** Custom mappers are specified when the `BingTextSearch` instance is created For Vector Store the implementation would look like: ```csharp public sealed class VectorTextSearch : ITextSearch where T : class { public async Task> SearchAsync(string query, SearchOptions? searchOptions = null, CancellationToken cancellationToken = default) { // Retrieve Vector Store search results if (typeof(T) == typeof(string)) { // Convert to string (custom mapper is supported) } else if (typeof(T) == typeof(TextSearchResult)) { // Convert to TextSearchResult (custom mapper is required) } else { // Return search results } } } ``` - Good, because can support custom types for `VectorTextSearch` - Neitral, because type checking required for each invocation - Bad, because not clear what return types are supported by an implementation ### 2. Define `ITextSearch` abstraction with single `Search` method and implementations implement what they support Abstraction would look like this: ```csharp public interface ITextSearch where T : class { public Task> SearchAsync(string query, SearchOptions? searchOptions = null, CancellationToken cancellationToken = default); } ``` Implementation would look like this: ```csharp public sealed class BingTextSearch : ITextSearch, ITextSearch, ITextSearch { /// async Task> ITextSearch.SearchAsync(string query, SearchOptions? searchOptions, CancellationToken cancellationToken) { // Retrieve Bing search results and convert to TextSearchResult } /// async Task> ITextSearch.SearchAsync(string query, SearchOptions? searchOptions, CancellationToken cancellationToken) { // Retrieve Bing search results } /// async Task> ITextSearch.SearchAsync(string query, SearchOptions? searchOptions, CancellationToken cancellationToken) { // Retrieve Bing search results and convert to string } } ``` For Vector Store the implementation would still look like: ```csharp public sealed class VectorTextSearch : ITextSearch where T : class { public async Task> SearchAsync(string query, SearchOptions? searchOptions = null, CancellationToken cancellationToken = default) { // Retrieve Vector Store search results if (typeof(T) == typeof(string)) { // Convert to string (custom mapper is supported) } else if (typeof(T) == typeof(TextSearchResult)) { // Convert to TextSearchResult (custom mapper is required) } else { // Return search results } } } ``` - Good, because separates the implementation for each return type where possible - Good, because it can be made clear what types are supported by an implementation - Bad, because you need to downcast ### 3. Define `ITextSearch` abstraction with multiple search methods Abstraction would look like this: ```csharp public interface ITextSearch where T : class { public Task> SearchAsync(string query, SearchOptions? searchOptions = null, CancellationToken cancellationToken = default); public Task> GetTextSearchResultsAsync(string query, SearchOptions? searchOptions = null, CancellationToken cancellationToken = default); public Task> GetSearchResultsAsync(string query, SearchOptions? searchOptions = null, CancellationToken cancellationToken = default); } ``` Implementation could look like this: ```csharp public sealed class BingTextSearch : ITextSearch { public async Task> GetSearchResultsAsync(string query, SearchOptions? searchOptions, CancellationToken cancellationToken) { // Retrieve Bing search results } public async Task> GetTextSearchResultsAsync(string query, SearchOptions? searchOptions, CancellationToken cancellationToken) { // Retrieve Bing search results and convert to TextSearchResult } public async Task> SearchAsync(string query, SearchOptions? searchOptions, CancellationToken cancellationToken) { // Retrieve Bing search results and convert to string } } ``` **Note:** This option would not be extensible i.e., to add support for Bing News search results we would have to add a new `BingNewTextSearch` implementation. For Vector Store the implementation would look like: ```csharp public sealed class VectorTextSearch : ITextSearch where T : class { public Task> GetSearchResultsAsync(string query, SearchOptions? searchOptions, CancellationToken cancellationToken) { // Retrieve Vector Store search results } public Task> GetTextSearchResultsAsync(string query, SearchOptions? searchOptions, CancellationToken cancellationToken) { // Retrieve Vector Store search results and convert to TextSearchResult } public Task> SearchAsync(string query, SearchOptions? searchOptions, CancellationToken cancellationToken) { // Retrieve Vector Store search results and convert to string } } ``` **Note:** This option would be extensible i.e., we can support custom record types in the underlying Vector Store implementation but developers will have to deal with run time exceptions if the type of record they specify is not supported. - Good, because there are separate methods for each type - Bad, because in the above BingTextSearch sample no additional types can be added - Bad, because not clear what types are supported ### 4. Define `ITextSearch` abstraction with multiple search methods and additional methods on implementations Abstraction would look like this: ```csharp public interface ITextSearch { public Task> SearchAsync(string query, SearchOptions? searchOptions = null, CancellationToken cancellationToken = default); public Task> GetTextSearchResultsAsync(string query, SearchOptions? searchOptions = null, CancellationToken cancellationToken = default); } ``` Implementation could look like this: ```csharp public sealed class BingTextSearch : ITextSearch { public async Task> GetTextSearchResultsAsync(string query, SearchOptions? searchOptions, CancellationToken cancellationToken) { // Retrieve Bing search results and convert to TextSearchResult } public async Task> SearchAsync(string query, SearchOptions? searchOptions, CancellationToken cancellationToken) { // Retrieve Bing search results and convert to string } public async Task> GetWebPagesAsync(string query, SearchOptions? searchOptions, CancellationToken cancellationToken) { // Retrieve Bing search results } } ``` **Note:** This option would be extensible i.e., to add support for Bing News search results we would just have to add a new method to `BingTextSearch`. For Vector Store the implementation would look like: ```csharp public sealed class VectorTextSearch : ITextSearch where T : class { public Task> GetSearchResultsAsync(string query, SearchOptions? searchOptions, CancellationToken cancellationToken) { // Retrieve Vector Store search results } public Task> GetTextSearchResultsAsync(string query, SearchOptions? searchOptions, CancellationToken cancellationToken) { // Retrieve Vector Store search results and convert to TextSearchResult } public Task> SearchAsync(string query, SearchOptions? searchOptions, CancellationToken cancellationToken) { // Retrieve Vector Store search results and convert to string } } ``` **Note:** This option would be extensible i.e., we can support custom record types in the underlying Vector Store implementation but developers will have to deal with run time exceptions if the type of record they specify is not supported. - Good, because there are separate methods for each type - Good, because support for additional types can be added - Good, because this will be easier to implement in Python - Bad, abstraction is limited to just including support for `string` and `TextSearchResult` ### 5. Define `ITextSearch` and `ITextSearch` abstractions Start with the `ITextSearch` abstraction and extend to include `ITextSearch` as needed. - Good, separate methods for each type - Good, support for additional types can be added - Good, additional abstraction using generics can be added when and if needed ## More Information ### Current Design The current design for search is divided into two implementations: 1. Search using a Memory Store i.e. Vector Database 1. Search using a Web Search Engine In each case a plugin implementation is provided which allows the search to be integrated into prompts e.g. to provide additional context or to be called from a planner or using auto function calling with a LLM. #### Memory Store Search The diagram below shows the layers in the current design of the Memory Store search functionality. Current Memory Design #### Web Search Engine Integration The diagram below shows the layers in the current design of the Web Search Engine integration. Current Web Search Design The Semantic Kernel currently includes experimental support for a `WebSearchEnginePlugin` which can be configured via a `IWebSearchEngineConnector` to integrate with a Web Search Services such as Bing or Google. The search results can be returned as a collection of string values or a collection of `WebPage` instances. - The `string` values returned from the plugin represent a snippet of the search result in plain text. - The `WebPage` instances returned from the plugin are a normalized subset of a complete search result. Each `WebPage` includes: - `name` The name of the search result web page - `url` The url of the search result web page - `snippet` A snippet of the search result in plain text The current design doesn't support breaking glass scenario's or using custom types for the response values. One goal of this ADR is to have a design where text search is unified into a single abstraction and a single plugin can be configured to perform web based searches or to search a vector store. ================================================ FILE: docs/decisions/0060-jsos-integration.md ================================================ --- # These are optional elements. Feel free to remove any of them. status: accepted contact: sergeymenshykh date: 2024-10-07 deciders: markwallace, sergeymenshykh, westey-m, consulted: eiriktsarpalis, stephentoub informed: --- # Considering Ways to Integrate JsonSerializerOptions into SK ## Context and Problem Statement Today, SK relies on JSON serialization and schema generation functionality to generate schemas for function parameters and return types, deserialize them from JSON to the target types as part of the marshaling process, serialize AI models to SK and back, etc. At the moment, the serialization code either uses no JsonSerializerOptions (JSOs) or uses hardcoded predefined ones for specific purposes without the ability to provide custom ones. This works perfectly fine for non-AOT scenarios where JSON serialization uses reflection by default. However, in Native AOT apps, which do not support all required reflection APIs, reflection-based serialization won't work and will crash. To enable serialization for Native-AOT scenarios, all serialization code should use source-generated context contracts represented by the `JsonSerializerContext` base class. See the article [How to use source generation in System.Text.Json](https://learn.microsoft.com/en-us/dotnet/standard/serialization/system-text-json/source-generation?pivots=dotnet-8-0#specify-source-generation-mode) for more details. Additionally, there should be a way to supply those source-generated classes via the SK public API surface down to the JSON serialization functionality. This ADR outlines potential options for passing JSOs with configured source-generated contracts down to the JSON serialization code of Native-AOT enabled SK components. ## Decision Drivers - It's possible to provide external source-generated context contracts down to SK JSON serialization functionality. - It's intuitively clear and easy to supply source-generated context contracts to SK components. - It's easy to integrate with Microsoft.Extensions.AI ## Considered Options - Option #1: One global JSOs for all SK components - Option #2: JSOs per SK component - Option #3: JSOs per SK component operation ## Option #1: One global JSOs for all SK components This options presumes adding the new `JsonSerializerOptions` property of `JsonSerializerOptions` type to `Kernel` class. All external source-generated context contracts will be registered there and all SK components requiring JSOs will resolve them from there: ```csharp public sealed class MyPlugin { public Order CreateOrder() => new(); } public sealed class Order { public string? Number { get; set; } } [JsonSerializable(typeof(Order))] internal sealed partial class OrderJsonSerializerContext : JsonSerializerContext { } public async Task TestAsync() { JsonSerializerOptions options = new JsonSerializerOptions(); options.TypeInfoResolverChain.Add(OrderJsonSerializerContext.Default); Kernel kernel = new Kernel(); kernel.JsonSerializerOptions = options; // All the following Kernel extension methods use JSOs configured on the `Kernel.JsonSerializerOptions` property kernel.CreateFunctionFromMethod(() => new Order()); kernel.CreateFunctionFromPrompt(""); kernel.CreatePluginFromFunctions("", [kernel.CreateFunctionFromMethod(() => new Order())]); kernel.CreatePluginFromType(""); kernel.CreatePluginFromPromptDirectory("", ""); kernel.CreatePluginFromObject(new MyPlugin(), ""); // AI connectors can use the `Kernel.JsonSerializerOptions` property as well var onnxService = new OnnxRuntimeGenAIChatCompletionService("", ""); var res = await onnxService.GetChatMessageContentsAsync(new ChatHistory(), new PromptExecutionSettings(), kernel); // The APIs below can't use the `Kernel.JsonSerializerOptions` property because they don't have access to the `Kernel` instance KernelFunctionFactory.CreateFromMethod(() => new Order(), options); KernelFunctionFactory.CreateFromPrompt("", options); KernelPluginFactory.CreateFromObject(new MyPlugin(), options, ""); KernelPluginFactory.CreateFromType(options, ""); KernelPluginFactory.CreateFromFunctions("", [kernel.CreateFunctionFromMethod(() => new Order())]); } ``` Pros: - All SK components use JSOs configured in one place. A kernel clone with different options can be provided if required. Cons: - May require changing the SK component to depend on the kernel if not already. - Depending on how JSOs are initialized, this option might not be as explicit as others regarding the usage of non-AOT compatible APIs in an AOT app, leading to trial-and-error to register source-generated contracts based on runtime errors. - Similar to the above, it may not be clear which component/API needs JSOs, postponing discovery to runtime. - Will add another way of providing JSOs in SK. Low-level KernelFunctionFactory and KernelPluginFactory accept JSOs via method parameters. - SK AI connectors accept an **optional** instance of the kernel in their operation, which sends mixed signals. On one hand, it's optional, meaning AI connectors can work without it; on the other hand, the operation will fail in an AOT app if no kernel is provided. - In scenarios that require more than one kernel instance, where each instance may have unique JSOs, the JSOs of the kernel a function was created with will be used for the lifetime of the function. JSOs from any other kernel the function might be invoked with won't be applied, and the ones from the kernel the function was created with will be used. ### Ways to Provide JSON Serializer Options (JSOs) to the Kernel: 1. Via `Kernel` constructor. ```csharp private readonly JsonSerializerOptions? _serializerOptions = null; // Existing AOT incompatible constructor [RequiresUnreferencedCode("Uses reflection to handle various aspects of JSON serialization in SK, making it incompatible with AOT scenarios.")] [RequiresDynamicCode("Uses reflection to handle various aspects of JSON serialization in SK, making it incompatible with AOT scenarios.")] public Kernel(IServiceProvider? services = null,KernelPluginCollection? plugins = null) {} // New AOT compatible constructor public Kernel(JsonSerializerOptions jsonSerializerOptions, IServiceProvider? services = null,KernelPluginCollection? plugins = null) { this._serializerOptions = jsonSerializerOptions; this._serializerOptions.MakeReadOnly(); // Prevent mutations that may not be picked up by SK components created with initial JSOs. } public JsonSerializerOptions JsonSerializerOptions => this._serializerOptions ??= JsonSerializerOptions.Default; ``` Pros: - AOT related warnings will be shown for the usage of a non-AOT compatible constructor at compile time. 2. Via the `Kernel.JsonSerializerOptions` property setter ```csharp private readonly JsonSerializerOptions? _serializerOptions = null; public JsonSerializerOptions JsonSerializerOptions { get { return this._serializerOptions ??= ??? // JsonSerializerOptions.Default will work for non-AOT scenarios and will fail in AOT ones. } set { this._serializerOptions = value; } } ``` Cons: - No AOT warning will be generated during kernel initialization in the AOT application, leading to a runtime failure. - JSOs assigned after an SK component (KernelFunction accepts JSOs via the constructor) is created won't be picked up by the component. 3. DI TBD after requirements are fleshed out. ## Option #2: JSOs per SK component This option presumes supplying JSOs at the component's instantiation site or constructor: ```csharp public sealed class Order { public string? Number { get; set; } } [JsonSerializable(typeof(Order))] internal sealed partial class OrderJsonSerializerContext : JsonSerializerContext { } JsonSerializerOptions options = new JsonSerializerOptions(); options.TypeInfoResolverChain.Add(OrderJsonSerializerContext.Default); // All the following kernel extension methods accept JSOs explicitly supplied as an argument for the corresponding parameter: kernel.CreateFunctionFromMethod(() => new Order(), options); kernel.CreateFunctionFromPrompt("", options); kernel.CreatePluginFromFunctions("", [kernel.CreateFunctionFromMethod(() => new Order(), options)]); kernel.CreatePluginFromType("", options); kernel.CreatePluginFromPromptDirectory("", "", options); kernel.CreatePluginFromObject(new MyPlugin(), "", options); // The AI connectors accept JSOs at the instantiation site rather than at the invocation site. var onnxService = new OnnxRuntimeGenAIChatCompletionService("", "", options); var res = await onnxService.GetChatMessageContentsAsync(new ChatHistory(), new PromptExecutionSettings()); // The APIs below already accept JSOs at the instantiation site. KernelFunctionFactory.CreateFromMethod(() => new Order(), options); KernelFunctionFactory.CreateFromPrompt("", options); KernelPluginFactory.CreateFromObject(new MyPlugin(), options, ""); KernelPluginFactory.CreateFromType(options, ""); KernelPluginFactory.CreateFromFunctions("", [kernel.CreateFunctionFromMethod(() => new Order())]); ``` Pros: - AOT warnings will be generated at compile time at each component instantiation site. - Same way of working with JSOs across all SK components. - Does't require SK components to depend on Kernel. Cons: - There's no central place to register source-generated contexts. It can be a advantage in cases where applications have a large amount of bootstrapping code residing in many different classes that may have inheritance relationships between them. AI connectors may accept JSOs as a parameter in the constructor or as an optional property. The decision will be made when one or a few connectors are refactored to be AOT compatible. ## Option #3: JSOs per SK component operation This option presumes supplying JSOs at component operation invocation sites rather than at instantiation sites. Pros: - AOT warnings will be generated during compile time at each component operation invocation site. Cons: - New operations/methods overloads accepting JSOs will have to be added for all SK components requiring external source-generated contracts. - Will add another way of providing JSOs in SK. Low-level KernelFunctionFactory and KernelPluginFactory accept JSOs via method parameters. - Not applicable to all SK components. KernelFunction needs JSOs before it is invoked for schema generation purposes. - Encourage ineffective usage of JSOs where JSOs may be created per method call, which may be expensive memory-wise. ## Decision Outcome The "Option #2 JSOs per SK component" was preferred over the other options since it provides an explicit, unified, clear, simple, and effective way of supplying JSOs at the component's instantiation/creation sites. ================================================ FILE: docs/decisions/0061-function-call-behavior.md ================================================ --- # These are optional elements. Feel free to remove any of them. status: accepted contact: sergeymenshykh date: 2024-04-22 deciders: markwallace, matthewbolanos, rbarreto, dmytrostruk, westey-m consulted: informed: --- # Function Call Behavior ## Context and Problem Statement Currently, every AI connector in SK that supports function calling has its own implementation of tool call behavior model classes. These classes are used to configure how connectors advertise and invoke functions. For instance, the behavior classes can specify which functions should be advertised to the AI model by a connector, whether the functions should be called automatically by the connector, or if the connector caller will invoke them manually. All the tool call behavior classes are the same in terms of describing the desired function call behavior. However, the classes have a mapping functionality that maps the function call behavior to the connector-specific model classes, which is what makes the function calling classes non-reusable between connectors. For example, [the constructor of the ToolCallBehavior class](https://github.com/microsoft/semantic-kernel/blob/aec65771c8c2443db2c832aed167bff566d4ab46/dotnet/src/Connectors/Connectors.OpenAI/ToolCallBehavior.cs#L172) references the [OpenAIFunction](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/src/Connectors/Connectors.OpenAI/Core/OpenAIFunction.cs) class, which is located in the `Microsoft.SemanticKernel.Connectors.OpenAI` namespace within the `Connectors.OpenAI` project. As a result, these classes cannot be reused by other connectors, such as the Mistral AI connector, without introducing an undesirable explicit project dependency from the `Connectors.Mistral` project to the `Connectors.OpenAI` project. Furthermore, it is currently not possible to specify function calling behavior declaratively in YAML or JSON prompts. ## Decision Drivers - There should be a single set of connector/model-agnostic function call behavior classes, enabling their use by all SK connectors that support function calling. - Function call behavior should be specified in the `PromptExecutionSettings` base class, rather than in its connector-specific derivatives. - It should be possible and straightforward to define function calling behavior in all currently supported prompt formats, including YAML (Handlebars, Prompty) and JSON (SK config.json). - Users should have the ability to override the prompt execution settings specified in the prompt with those defined in the code. ## Existing function calling behavior model - ToolCallBehavior Today, SK utilizes the `ToolCallBehavior` abstract class along with its derivatives: `KernelFunctions`, `EnabledFunctions`, and `RequiredFunction` to define the function-calling behavior for the OpenAI connector. This behavior is specified through the `OpenAIPromptExecutionSettings.ToolCallBehavior` property. The model is consistent across other connectors, differing only in the names of the function call behavior classes. ```csharp OpenAIPromptExecutionSettings settings = new() { ToolCallBehavior = ToolCallBehavior.AutoInvokeKernelFunctions }; or GeminiPromptExecutionSettings settings = new() { ToolCallBehavior = GeminiToolCallBehavior.AutoInvokeKernelFunctions }; ``` Considering that the function-calling behavior has been in place since the SK v1 release and may be used extensively, the new function-calling abstraction must be introduced to coexist alongside the existing function-calling model. This approach will prevent breaking changes and allow consumers to gradually transition from the current model to the new one. ## [New model] Option 1.1 - A class per function choice To meet the "no breaking changes" requirement and the "connector/model-agnostic" design principle, a new set of connector-agnostic classes needs to be introduced. ### Function choice classes The `FunctionChoiceBehavior` class is abstract base class for all *FunctionChoiceBehavior derivatives. ```csharp public abstract class FunctionChoiceBehavior { public static FunctionChoiceBehavior Auto(IEnumerable? functions = null, bool autoInvoke = true, FunctionChoiceBehaviorOptions? options = null) { ... } public static FunctionChoiceBehavior Required(IEnumerable? functions = null, bool autoInvoke = true, FunctionChoiceBehaviorOptions? options = null) { ... } public static FunctionChoiceBehavior None(IEnumerable? functions = null, FunctionChoiceBehaviorOptions? options = null) public abstract FunctionChoiceBehaviorConfiguration GetConfiguration(FunctionChoiceBehaviorConfigurationContext context); } ``` All derivatives of the `FunctionChoiceBehavior` class must implement the abstract `GetConfiguration` method. This method is called with a `FunctionChoiceBehaviorConfigurationContext` provided by the connectors. It returns a `FunctionChoiceBehaviorConfiguration` object to the connectors, instructing them on how to behave based on the specific function call choice behavior defined by the corresponding class regarding function calling and invocation. ```csharp public class FunctionChoiceBehaviorConfigurationContext { public Kernel? Kernel { get; init; } public ChatHistory ChatHistory { get; } public int RequestSequenceIndex { get; init; } } public class FunctionChoiceBehaviorConfiguration { public FunctionChoice Choice { get; internal init; } public IReadOnlyList? Functions { get; internal init; } public bool AutoInvoke { get; set; } = true; public FunctionChoiceBehaviorOptions Options { get; } } ``` The `AutoFunctionChoiceBehavior` class can advertise either all kernel functions or a specified subset of functions, which can be defined through its constructor or the `Functions` property. Additionally, it instructs the AI model on whether to call the functions and, if so, which specific functions to invoke. ```csharp public sealed class AutoFunctionChoiceBehavior : FunctionChoiceBehavior { [JsonConstructor] public AutoFunctionChoiceBehavior() { } public AutoFunctionChoiceBehavior(IEnumerable? functions, bool autoInvoke, FunctionChoiceBehaviorOptions? options) { } [JsonPropertyName("functions")] public IList? Functions { get; set; } [JsonPropertyName("options")] public FunctionChoiceBehaviorOptions? Options { get; set; } public override FunctionChoiceBehaviorConfiguration GetConfiguration(FunctionChoiceBehaviorConfigurationContext context) { var functions = base.GetFunctions(this.Functions, context.Kernel, this._autoInvoke); return new FunctionChoiceBehaviorConfiguration(this.Options ?? DefaultOptions) { Choice = FunctionChoice.Auto, Functions = functions, AutoInvoke = this._autoInvoke, }; } } ``` The `RequiredFunctionChoiceBehavior` class, like the `AutoFunctionChoiceBehavior` class, can advertise either all kernel functions or a specified subset of functions, which can be defined through its constructor or the `Functions` property. However, it differs by mandating that the model must call the provided functions. ```csharp public sealed class RequiredFunctionChoiceBehavior : FunctionChoiceBehavior { [JsonConstructor] public RequiredFunctionChoiceBehavior() { } public RequiredFunctionChoiceBehavior(IEnumerable? functions, bool autoInvoke, FunctionChoiceBehaviorOptions? options) { } [JsonPropertyName("functions")] public IList? Functions { get; set; } [JsonPropertyName("options")] public FunctionChoiceBehaviorOptions? Options { get; set; } public override FunctionChoiceBehaviorConfiguration GetConfiguration(FunctionChoiceBehaviorConfigurationContext context) { // Stop advertising functions after the first request to prevent the AI model from repeatedly calling the same function. // This is a temporary solution which will be removed after we have a way to dynamically control list of functions to advertise to the model. if (context.RequestSequenceIndex >= 1) { return new FunctionChoiceBehaviorConfiguration(this.Options ?? DefaultOptions) { Choice = FunctionChoice.Required, Functions = null, AutoInvoke = this._autoInvoke, }; } var functions = base.GetFunctions(this.Functions, context.Kernel, this._autoInvoke); return new FunctionChoiceBehaviorConfiguration(this.Options ?? DefaultOptions) { Choice = FunctionChoice.Required, Functions = functions, AutoInvoke = this._autoInvoke, }; } } ``` The `NoneFunctionChoiceBehavior` class, like the other behavior classes, can advertise either all kernel functions or a specified subset of functions, which can be defined through its constructor or the `Functions` property. Additionally, it instructs the AI model to utilize the provided functions without calling them to generate a response. This behavior may be useful for dry runs when you want to see which functions the model would call without actually invoking them. ```csharp public sealed class NoneFunctionChoiceBehavior : FunctionChoiceBehavior { [JsonConstructor] public NoneFunctionChoiceBehavior() { } public NoneFunctionChoiceBehavior(IEnumerable? functions, FunctionChoiceBehaviorOptions? options) { } [JsonPropertyName("functions")] public IList? Functions { get; set; } [JsonPropertyName("options")] public FunctionChoiceBehaviorOptions? Options { get; set; } public override FunctionChoiceBehaviorConfiguration GetConfiguration(FunctionChoiceBehaviorConfigurationContext context) { var functions = base.GetFunctions(this.Functions, context.Kernel, autoInvoke: false); return new FunctionChoiceBehaviorConfiguration(this.Options ?? DefaultOptions) { Choice = FunctionChoice.None, Functions = functions, AutoInvoke = false, }; } } ``` To meet the requirements of the 'connector/model-agnostic' driver, the function choice behavior should be configurable within the model-agnostic `PromptExecutionSettings` class, rather than within the model-specific prompt execution setting classes, such as `OpenAIPromptExecutionSettings`, as is currently done. ```csharp PromptExecutionSettings settings = new() { FunctionChoiceBehavior = FunctionChoiceBehavior.Required() }; ``` All of the function choice behavior classes described above include a `Functions` property of type `IList`. Functions can be specified as strings in the format `pluginName.functionName`. The primary purpose of this property is to allow users to declare the list of functions they wish to advertise to the AI model in YAML, Markdown, or JSON prompts. However, it can also be utilized to specify the functions in code, although it is generally more convenient to do this through the constructors of the function choice behavior classes, which accept a list of `KernelFunction` instances. Additionally, the function choice behavior classes feature an `Options` property of type `FunctionChoiceBehaviorOptions`, which can be provided via the constructor or set directly on the class instance. This property enables users to configure various aspects of the function choice behavior, such as whether the AI model should prefer parallel function invocations over sequential ones. The intention is for this class to evolve over time, incorporating properties that are relevant to the majority of AI models. In cases where a specific AI model requires unique properties that are not supported by other models, a model-specific derivative options class can be created. This class can be recognized by the SK AI connector for that model, allowing it to read the specific properties. ### Sequence diagram Tool choice behavior usage by AI service.png ### Support of the behaviors in prompts Given the hierarchical nature of the choice behavior model classes, polymorphic deserialization should be enabled for situations where functional choice behavior needs to be configured in JSON and YAML prompts. ```json { ... "execution_settings": { "default": { "temperature": 0.4, "function_choice_behavior": { "type": "auto", //possible values - auto, required, none "functions": [ "plugin1.function1", "plugin1.function2", ], "options": { "allow_concurrent_invocation": true } } } } } ``` ```yaml execution_settings: default: temperature: 0.4 function_choice_behavior: type: auto functions: - plugin1.function1 - plugin1.function2 options: allow_concurrent_invocation: true ``` Polymorphic deserialization is supported by System.Text.Json.JsonSerializer and requires registering all the types that will be used for polymorphic deserialization, in advance, before they can be used. This can be done either by annotating the base class with the JsonDerivedType attribute to specify a subtype of the base type, or alternatively, by registering the subtypes in TypeInfoResolver, which needs to be supplied via JsonSerializerOptions for use during deserialization. More details can be found here: [Serialize polymorphic types](https://learn.microsoft.com/en-us/dotnet/standard/serialization/system-text-json/polymorphism?pivots=dotnet-8-0). To support custom function choice behaviors, the custom types should be registered for polymorphic deserialization. Clearly, the approach using the JsonDerivedType attribute is not viable, as users cannot annotate `FunctionChoiceBehavior` SK class. However, they could register their custom type resolver that would register their custom type(s) if they had access to JsonSerializerOptions used by JsonSerializer during deserialization. Unfortunately, SK does not expose those options publicly today. Even if it had, there are YAML prompts that are deserialized by the YamlDotNet library that would require same custom types supplied via YAML specific deserializer extensibility mechanisms - YamlTypeConverter. This would mean that if a user wants the same custom function calling choice to be used in both YAML and JSON prompts, they would have to register the same custom type twice - for JSON via a custom type resolver and for YAML via a custom YamlTypeConverter. That would also require a mechanism of supplying custom resolvers/converters to all SK `CreateFunctionFrom*Prompt` extension methods. Polymorphic deserialization is supported by `System.Text.Json.JsonSerializer` and requires that all types intended for polymorphic deserialization be registered in advance. This can be accomplished either by annotating the base class with the `JsonDerivedType` attribute to specify a subtype of the base type or by registering the subtypes with `TypeInfoResolver`, which must be provided via `JsonSerializerOptions` for use during deserialization. More details can be found here: [Serialize polymorphic types](https://learn.microsoft.com/en-us/dotnet/standard/serialization/system-text-json/polymorphism?pivots=dotnet-8-0). ### Location of the function choice behavior node SK prompts may contain one or more entries, each corresponding to a service, which specify execution settings to describe service-specific configurations within a prompt. Since each section is deserialized into an instance of the `PromptExecutionSettings` class, which is utilized by the respective service, it is logical to define the function behavior in each service configuration section. However, this approach may lead to unnecessary duplication, as all services might require the same choice behavior. Furthermore, there may be scenarios where two out of three services share the same choice behavior configuration, while the remaining service uses a different one. ```json "function_choice_behavior":{ ... }, "execution_settings": { "default": { "temperature": 0, "function_choice_behavior":{ ... } }, "gpt-3.5-turbo": { "model_id": "gpt-3.5-turbo-0613", "temperature": 0.1, "function_choice_behavior":{ ... } }, "gpt-4": { "model_id": "gpt-4-1106-preview", "temperature": 0.3, "function_choice_behavior":{ ... } } } ``` To address the scenarios mentioned above, it is advisable to implement an inheritance mechanism that allows a service to inherit the parent function choice behavior configuration, if specified. Regardless of whether the parent has a function choice behavior configuration defined, it should be possible to specify or override the parent's configuration at each service entry level. ### Breaking glass support The list of choice classes described above may not be sufficient to cover all scenarios that users might encounter. To address this, the `FunctionCallChoice.Configure` method accepts an instance of the model connector used internally, enabling users to access and modify it from within the configuration method of a custom function call choice. ```csharp // Custom function call choice public sealed class NewCustomFunctionChoiceBehavior : FunctionChoiceBehavior { public override FunctionChoiceBehaviorConfiguration GetConfiguration(FunctionChoiceBehaviorContext context) { var model = context.Model; // The CompletionsOptions, ChatCompletionsToolChoice, etc are data model classes used by the OpenAIChatCompletionService connector internally. ((CompletionsOptions)model).ToolChoice = new ChatCompletionsToolChoice(new FunctionDefinition("NEW-TOOL-CHOICE-MODE")); ((CompletionsOptions)model).Tools.Add(new ChatCompletionsFunctionToolDefinition(); return new FunctionChoiceBehaviorConfiguration() { Model = model; // Return the model back to the calling connector to indicate that we control the function call choice ourselves, and there is no need to apply the mapping logic connector side that would be applied otherwise. MaximumAutoInvokeAttempts = this.MaximumAutoInvokeAttempts, MaximumUseAttempts = this.MaximumUseAttempts, AllowAnyRequestedKernelFunction = false }; } } ... // Registering the custom choice PromptExecutionSettings settings = new() { FunctionChoiceBehavior = new NewCustomFunctionChoiceBehavior() }; ``` ## [New model] Option 1.2 - alternative design Explore the possibility of resolving specific types during a post-deserialization phase in a location that has access to a kernel instance, eliminating the need for polymorphic deserialization. This approach would enable the resolution of custom function choice behavior classes that users register in the kernel service collection. Users can register their custom classes, which will then be automatically selected either during prompt rendering or when the information is needed, regardless of the prompt format whether it's JSON or YAML. ## 2. Separation of function call choice and function invocation configs The new model should accommodate scenarios where one person engineers the prompt while another executes or invokes it. One way to achieve this is by separating function choice behavior configuration such as auto, enabled, and none from function invocation configuration, which includes settings like AllowParallelCalls. The function choice behavior configuration can still be provided through PromptExecutionSettings, but the appropriate location for supplying the function invocation configuration needs to be identified. Additionally, it should be possible to override function choice behavior directly from the code. Below are several options for potential locations to supply function invocation configuration via the code: ### Option 2.1 - Invocation config as a parameter of the `IChatCompletionService.GetChatMessageContentsAsync` method and its streaming counterpart. Pros: - The function invocation configuration can be specified for each operation, rather than being limited to the overall AI service configuration. Cons: - Introducing a new parameter to the interface methods will create breaking changes that will impact all non-SK custom implementations of the interface. - This approach diverges from the current development experience, which allows both configurations to be supplied through connector-specific prompt execution settings. ### Option 2.2 - Invocation config as a constructor parameter of each implementation of the `IChatCompletionService` interface. Pros: - There is no need to change the interface method signatures, which means that no non-SK custom implementations will be broken. Cons: - The function invocation configuration will be applied at the service level during the service registration phase. If some operations require different configurations, a new service with a distinct configuration will need to be registered. - This approach diverges from the current development experience, where both configurations are provided through connector-specific prompt execution settings. ### Option 2.3 - Invocation config as `Kernel.FunctionInvocationConfig` property. Pros: - No breaking changes: The signatures of both `IChatCompletionService` members and its implementation constructors remain unchanged. Cons: - A new kernel must be created, or an existing one must be cloned, each time a different configuration is required. - The kernel will contain more AI connector-specific logic. - This approach deviates from the current development experience, where both configurations are provided through connector-specific prompt execution settings. ### Option 2.4 - Invocation config as item in `Kernel.Data` collection. Pros: - No breaking changes: The signatures of both `IChatCompletionService` members and its implementation constructors remain unchanged. - No AI connector-specific logic is added to the kernel. Cons: - Requires a magic constant that is not enforced by the compiler. - A new kernel must be created, or an existing one must be cloned, each time a different configuration is needed. - This approach deviates from the current development experience, where both configurations are provided through connector-specific prompt execution settings. ### Option 2.5 - The `PromptExecutionSettings.FunctionChoiceBehavior` property for both function call choice config and invocation config Pros: - This approach is proposed in Option #1.1, where both configurations are supplied through connector-agnostic prompt execution settings. - No breaking changes: The signatures of both `IChatCompletionService` members and its implementation constructors remain unchanged. Cons: - A new service selector must be implemented and registered in the kernel to merge execution settings provided via the prompt with those supplied by developers at the invocation step ## Decision Outcome There were a few decisions taken during the ADR review: - Option 1.1 was chosen as the preferred option for the new function call behavior model. - It was decided to postpone the implementation of the inheritance mechanism that allows a service to inherit the parent function choice behavior configuration. - It was decided that the Breaking Glass support is out of scope for now, but it may be included later if necessary. - Option 2.5, which presumes supplying function call choices and function invocation configurations via prompt execution settings, was preferred over the other options due to its simplicity, absence of breaking changes, and familiar developer experience. ================================================ FILE: docs/decisions/0062-open-api-payload.md ================================================ --- status: proposed contact: sergeymenshykh date: 2024-10-25 deciders: dmytrostruk, markwallace, rbarreto, sergeymenshykh, westey-m, --- # Providing Payload for OpenAPI Functions ## Context and Problem Statement Today, SK OpenAPI functions' payload can either be provided by a caller or constructed dynamically by SK from OpenAPI document metadata and provided arguments. This ADR provides an overview of the existing options that OpenAPI functionality currently has for handling payloads and proposes a new option to simplify dynamic creation of complex payloads. ## Overview of Existing Options for Handling Payloads in SK ### 1. The `payload` and the `content-type` Arguments This option allows the caller to create payload that conforms to the OpenAPI schema and pass it as an argument to the OpenAPI function when invoking it. ```csharp // Import an OpenAPI plugin with the createEvent function and disable dynamic payload construction KernelPlugin plugin = await kernel.ImportPluginFromOpenApiAsync("", new Uri(""), new OpenApiFunctionExecutionParameters { EnableDynamicPayload = false }); // Create the payload for the createEvent function string payload = """ { "subject": "IT Meeting", "start": { "dateTime": "2023-10-01T10:00:00", "timeZone": "UTC" }, "end": { "dateTime": "2023-10-01T11:00:00", "timeZone": "UTC" }, "tags": [ { "name": "IT" }, { "name": "Meeting" } ] } """; // Create arguments for the createEvent function KernelArguments arguments = new () { ["payload"] = payload, ["content-type"] = "application/json" }; // Invoke the createEvent function FunctionResult functionResult = await kernel.InvokeAsync(plugin["createEvent"], arguments); ``` Note that Semantic Kernel does not validate or modify the payload in any way. It is the caller's responsibility to ensure that the payload is valid and conforms to the OpenAPI schema. ### 2. Dynamic Payload Construction From Leaf Properties This option allows SK to construct the payload dynamically based on the OpenAPI schema and the provided arguments. The caller does not need to provide the payload when invoking the OpenAPI function. However, the caller must provide the arguments that will be used as values for the payload properties of the same name. ```csharp // Import an OpenAPI plugin with the createEvent function and disable dynamic payload construction KernelPlugin plugin = await kernel.ImportPluginFromOpenApiAsync("", new Uri(""), new OpenApiFunctionExecutionParameters { EnableDynamicPayload = true // It's true by default }); // Expected payload structure //{ // "subject": "...", // "start": { // "dateTime": "...", // "timeZone": "..." // }, // "duration": "PT1H", // "tags":[{ // "name": "...", // } // ], //} // Create arguments for the createEvent function KernelArguments arguments = new() { ["subject"] = "IT Meeting", ["dateTime"] = DateTimeOffset.Parse("2023-10-01T10:00:00"), ["timeZone"] = "UTC", ["duration"] = "PT1H", ["tags"] = new[] { new Tag("work"), new Tag("important") } }; // Invoke the createEvent function FunctionResult functionResult = await kernel.InvokeAsync(plugin["createEvent"], arguments); ``` This option traverses the payload schema starting from the root properties down and collects all leaf properties (properties that do not have any child properties) along the way. The caller must provide arguments for the identified leaf properties, and SK will construct the payload based on the schema and the provided arguments. There is a limitation with this option regarding the creation of payloads that contain properties with the same names at different levels. Taking into account that import process creates a kernel function for each OpenAPI operation, there's no feasible way to create a kernel function with more than one parameter having the same name. An attempt to import a plugin with such a payload will fail with the following error: "The function has two or more parameters with the same name ``." Additionally, there's probability of circular references in the payload schema that may occur when two or more properties reference each other, creating a loop. SK will detect such circular references and throw an error failing the operation import. Another specificity of this option is that it does not traverse array properties and considers them as leaf properties. This means that the caller must provide arguments for the properties of the array type, but not for the array elements or the properties of the array elements. In the example above, the array of objects should be provided as an argument for the "tags" array property. ### 3. Dynamic Payload Construction From Leaf Properties Using Namespaces This option addresses the limitation of the dynamic payload construction option described above regarding handling properties with the same name at different levels. It does so by prepending child property names with their parent property names, effectively creating unique names. The caller still needs to provide arguments for the properties and SK will do the rest. ```csharp // Import an OpenAPI plugin with the createEvent function and disable dynamic payload construction KernelPlugin plugin = await kernel.ImportPluginFromOpenApiAsync("", new Uri(""), new OpenApiFunctionExecutionParameters { EnableDynamicPayload = true, EnablePayloadNamespacing = true }); // Expected payload structure //{ // "subject": "...", // "start": { // "dateTime": "...", // "timeZone": "..." // }, // "end": { // "dateTime": "...", // "timeZone": "..." // }, // "tags":[{ // "name": "...", // } // ], //} // Create arguments for the createEvent function KernelArguments arguments = new() { ["subject"] = "IT Meeting", ["start.dateTime"] = DateTimeOffset.Parse("2023-10-01T10:00:00"), ["start.timeZone"] = "UTC", ["end.dateTime"] = DateTimeOffset.Parse("2023-10-01T11:00:00"), ["end.timeZone"] = "UTC", ["tags"] = new[] { new Tag("work"), new Tag("important") } }; // Invoke the createEvent function FunctionResult functionResult = await kernel.InvokeAsync(plugin["createEvent"], arguments); ``` This option, like the previous one, traverses the payload schema from the root properties down to collect all leaf properties. When a leaf property is encountered, SK checks for a parent property. If a parent exists, the leaf property name is prepended with the parent property name, separated by a dot, to create a unique name. For instance, the `dateTime` property of the `start` object will be named `start.dateTime`. This option treats array properties in the same way as the previous one, considering them as leaf properties, which means the caller must supply arguments for them. This option is susceptible to circular references in the payload schema as well, and SK will fail the operation import if it detects any. ## New Options for Handling Payloads in SK ### Context and Problem Statement SK goes above and beyond to handle the complexity of constructing payloads dynamically and offloading this responsibility from the caller. However, neither of the existing options is suitable for complex scenarios when the payload contains properties with the same name at different levels and using namespaces is not an option. To cover these scenarios, we propose a new option for handling payloads in SK. ### Considered Options - Option #4: Construct payload out of root properties ### Option #4: Dynamic Payload Construction From Root Properties There could be cases when the payload contains properties with the same name, and using namespaces is not possible for a various reasons. In order not to offload the responsibility of constructing the payload to the caller, SK can do an extra step and construct the payload out of the root properties. Of cause the complexity of building arguments for those root properties will be on the caller side but there's not much SK can do if it's not allowed to use namespaces and arguments for properties with the same name at different levels have to be resolved from the flat list of kernel arguments. ```csharp // Import an OpenAPI plugin with the createEvent function and disable dynamic payload construction KernelPlugin plugin = await kernel.ImportPluginFromOpenApiAsync("", new Uri(""), new OpenApiFunctionExecutionParameters { EnableDynamicPayload = false, EnablePayloadNamespacing = true }); // Expected payload structure //{ // "subject": "...", // "start": { // "dateTime": "...", // "timeZone": "..." // }, // "end": { // "dateTime": "...", // "timeZone": "..." // }, // "tags":[{ // "name": "...", // } // ], //} // Create arguments for the createEvent function KernelArguments arguments = new() { ["subject"] = "IT Meeting", ["start"] = new MeetingTime() { DateTime = DateTimeOffset.Parse("2023-10-01T10:00:00"), TimeZone = TimeZoneInfo.Utc }, ["end"] = new MeetingTime() { DateTime = DateTimeOffset.Parse("2023-10-01T10:00:00"), TimeZone = TimeZoneInfo.Utc }, ["tags"] = new[] { new Tag("work"), new Tag("important") } }; // Invoke the createEvent function FunctionResult functionResult = await kernel.InvokeAsync(plugin["createEvent"], arguments); ``` This option naturally fits between existing option #1. The `payload` and the `content-type` Arguments and option #2. Dynamic Payload Construction Using Leaf Properties as shown in the overview table below. ### Options Overview | Option | Caller | SK | Limitations | |--------|-------|----|--------| | 1. The `payload` and the `content-type` Arguments | Constructs payload | Use it as is | No limitations | | 4. Dynamic Payload Construction From Root Properties | Provides arguments for root properties | Constructs payload | 1. No support for `anyOf`, `allOf`, `oneOf` | | 2. Dynamic Payload Construction From Leaf Properties | Provides arguments for leaf properties | Constructs payload | 1. No support for `anyOf`, `allOf`, `oneOf`, 2. Leaf properties must be unique, 3. Circular references | | 3. Dynamic Payload Construction From Leaf Properties + Namespaces | Provides arguments for namespaced properties | Constructs payload | 1. No support for `anyOf`, `allOf`, `oneOf`, 2. Circular references | ### Decision Outcome Having discussed these options, it was decided not to proceed with implementation of Option #4 because of absence of strong evidence that it provides any benefits over the existing Option #1. ## Samples Samples demonstrating the usage of the existing options described above can be found in the [Semantic Kernel Samples repository](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/samples/Concepts/Plugins/OpenApiPlugin_PayloadHandling.cs) ================================================ FILE: docs/decisions/0063-function-calling-reliability.md ================================================ --- status: proposed contact: sergeymenshykh date: 2025-01-21 deciders: dmytrostruk, markwallace, rbarreto, sergeymenshykh, westey-m, consulted: stephentoub --- # Function Calling Reliability ## Context and Problem Statement One key aspect of function calling, that determines the reliability of SK function calling, is the AI model's ability to call functions using the exact names with which they were advertised. More often than wanted, the AI model hallucinates function names when calling them. In majority of cases, it's only one character in function name that is hallucinated, and the rest of the function name is correct. This character is the hyphen character `-` that SK uses as a separator between plugin name and function name to form the function fully qualified name (FQN) when advertising the function to uniquely identify functions across all plugins. For example, if the plugin name is `foo` and the function name is `bar`, the FQN of the function is `foo-bar`. The hallucinated names seen so far are `foo_bar`, `foo.bar`. ### Issue #1: Underscore Separator Hallucination - `foo_bar` When the AI model hallucinates the underscore separator `_`, SK detects this error and returns the message _"Error: Function call request for a function that wasn't defined."_ to the model as part of the function result, along with the original function call, in the subsequent request. Some models can automatically recover from this error and call the function using the correct name, while others cannot. ### Issue #2: Dot Separator Hallucination - `foo.bar` This issue is similar to the Issue #1, but in this case the separator is `.`. Although the SK detects this error and tries to return it to the AI model in the subsequent request, the request fails with the exception: _"Invalid messages[3].tool_calls[0].function.name: string does not match pattern. Expected a string that matches the pattern ^[a-zA-Z0-9_-]+$."_ The reason for this failure is that the hallucinated separator `.` is not permitted in the function name. Essentially, the model rejects the function name it hallucinated itself. ### Issue #3: Reliability of the Auto-Recovery Mechanism When a function is called using a name different from its advertised name, the function cannot be found, resulting in an error message being returned to the AI model, as described above. This error message provides the AI model with a hint about the issue, helping it to auto-recover by calling the function using the correct name. However, the auto-recovery mechanism does not operate reliably across different models. For instance, it works with the `gpt-4o-mini(2024-07-18)` model but fails with the `gpt-4(0613)` and `gpt-4o(2024-08-06)` ones. When the AI model is unable to recover, it simply returns a variation of the error message: _"I'm sorry, but I can't provide the answer right now due to a system error. Please try again later."_ ## Decision Drivers - Minimize the occurrence of function name hallucinations. - Enhance the reliability of the auto-recovery mechanism. ## Considered Options Some of the options are not mutually exclusive and can be combined. ### Option 1: Use Only Function Name for Function FQN This option proposes using only the function name as function's FQN. For example, the FQN for the function `bar` from the plugin `foo` would simply be `bar`. By using only the function name, we eliminate the need for the separator `-`, which is often hallucinated. Pros: - Reduces or eliminates function name hallucinations by removing the source of hallucination (Issues #1 and #2). - Decreases the number of tokens consumed by the plugin name in the function FQN. Cons: - Function names may not be unique across all plugins. For instance, if two plugins have a function with the same name, both will be provided to the AI model, and SK will invoke the first function it encounters. - [From the ADR review meeting] If duplicates are found, the plugin name can be dynamically added to the duplicates or to all advertised functions. - The lack of the plugin name may result in insufficient context for function names. For example, the function `GetData` has different meanings in the context of the `Weather` plugin compared to the `Stocks` plugin. - [From the ADR review meeting] The plugin name/context can be added to function names or descriptions by the plugin developer or automatically to the function descriptions by SK. - It cannot address hallucinated function names. For instance, if the AI model hallucinates the function FQN `b0r` instead of `bar`. Possible implementations: ```csharp // Either at the operation level FunctionChoiceBehaviorOptions options = new new() { UseFunctionNameAsFqn = true }; var settings = new AzureOpenAIPromptExecutionSettings() { FunctionChoiceBehavior = FunctionChoiceBehavior.Auto(options) }; var result = await this._chatCompletionService.GetChatMessageContentAsync(chatHistory, settings, this._kernel); // Or at the AI connector configuration level IKernelBuilder builder = Kernel.CreateBuilder(); builder.AddOpenAIChatCompletion("", "", functionNamePolicy: FunctionNamePolicy.UseFunctionNameAsFqn); // Or at the plugin level string pluginName = string.Empty; // If the plugin name is not an empty string, it will be used as the plugin name. // If it is null, then the plugin name will be inferred from the plugin type. // Otherwise, if the plugin name is an empty string, the plugin name will be omitted, // and all its functions will be advertised without a plugin name. kernel.ImportPluginFromType(pluginName); ``` ### Option 2: Custom Separator This option proposes making the separator character, or a sequence of characters, configurable. Developers can specify a separator that is less likely to be mistakenly generated by the AI model. For example, they may choose `_` or `a1b` as the separator. This solution may reduce the occurrences of function name hallucinations (Issues #1 and #2). Pros: - Reduces function name hallucinations by changing the separator to a less likely hallucinated character. Cons: - It won't work for cases when the separator is used in plugin name. For example the underscore symbol can be part of the `my_plugin` plugin name and also used as a separator, resulting in `my_plugin_myfunction` FQN. - [From the ADR review meeting] SK can dynamically remove any occurrences of the separator in plugin names and function names before advertising them. - It can't address hallucinated function names. For instance, if the AI model generates the function FQN as `MyPlugin_my_func` instead of `MyPlugin_my_function`. Possible implementations: ```csharp // Either at the operation level FunctionChoiceBehaviorOptions options = new new() { FqnSeparator = "_" }; var settings = new AzureOpenAIPromptExecutionSettings() { FunctionChoiceBehavior = FunctionChoiceBehavior.Auto(options) }; var result = await this._chatCompletionService.GetChatMessageContentAsync(chatHistory, settings, this._kernel); // Or at the AI connector configuration level IKernelBuilder builder = Kernel.CreateBuilder(); builder.AddOpenAIChatCompletion("", "", functionNamePolicy: FunctionNamePolicy.Custom("_")); ``` ### Option 3: No Separator This option proposes not using any separator between the plugin name and the function name. Instead, they will be concatenated directly. For example, the FQN for the function `bar` from the plugin `foo` would be `foobar`. Pros: - Reduces function name hallucinations by eliminating the source of hallucination (Issues #1 and #2). Cons: - Requires a different function lookup heuristic. ### Option 4: Custom FQN Parser This option proposes a custom, external FQN parser that can split function FQN into plugin name and function name. The parser will accepts the function FQN called by the AI model and returns both the plugin name and function name. To achieve this, the parser will attempt to parse the FQN using various separator characters: ```csharp static (string? PluginName, string FunctionName) ParseFunctionFqn(ParseFunctionFqnContext context) { static (string? PluginName, string FunctionName)? Parse(ParseFunctionFqnContext context, char separator) { string? pluginName = null; string functionName = context.FunctionFqn; int separatorPos = context.FunctionFqn.IndexOf(separator, StringComparison.Ordinal); if (separatorPos >= 0) { pluginName = context.FunctionFqn.AsSpan(0, separatorPos).Trim().ToString(); functionName = context.FunctionFqn.AsSpan(separatorPos + 1).Trim().ToString(); } // Check if the function registered in the kernel if (context.Kernel is { } kernel && kernel.Plugins.TryGetFunction(pluginName, functionName, out _)) { return (pluginName, functionName); } return null; } // Try to use use hyphen, dot, and underscore sequentially as separators. var result = Parse(context, '-') ?? Parse(context, '.') ?? Parse(context, '_'); if (result is not null) { return result.Value; } // If no separator is found, return the function name as is allowing AI connector to apply default behavior. return (null, context.FunctionFqn); } ``` [From the ADR review meeting] Alternatively, the parser can return the function itself. This needs to be investigated further. This [PR](https://github.com/microsoft/semantic-kernel/pull/10206) can provide more insights into how and where the parser is used. Pros: - It will mitigate but not reduce or completely eliminate function separator hallucinations by applying a custom heuristic specific to the AI model to parse the function FQN. - It can be easily implemented in SK AI connectors. Possible implementations: ```csharp // Either at the operation level static (string? PluginName, string FunctionName) ParseFunctionFqn(ParseFunctionFqnContext context) { ... } FunctionChoiceBehaviorOptions options = new new() { FqnParser = ParseFunctionFqn }; var settings = new AzureOpenAIPromptExecutionSettings() { FunctionChoiceBehavior = FunctionChoiceBehavior.Auto(options) }; var result = await this._chatCompletionService.GetChatMessageContentAsync(chatHistory, settings, this._kernel); // Or at the AI connector configuration level IKernelBuilder builder = Kernel.CreateBuilder(); builder.AddOpenAIChatCompletion("", "", functionNamePolicy: FunctionNamePolicy.Custom("_", ParseFunctionFqn)); ``` ### Option 5: Improved Auto-Recovery Mechanism Currently, when a function that was not advertised is called, SK returns the error message: _"Error: Function call request for a function that wasn't defined."_ Among the three AI models `gpt-4(0613)`, `gpt-4o-mini(2024-07-18)`, and `gpt-4o(2024-08-06)` only `gpt-4o-mini` can automatically recover from this error and successfully call the function using the correct name. The other two models fail to recover and instead return a final message similar to: _"I'm sorry, but I can't provide the answer right now due to a system error."_ However, by adding function name to the error message - "Error: Function call request for **foo.bar** function that wasn't defined." and the "You can call tools. If a tool call failed, correct yourself." system message to chat history, all three models can auto-recover from the error and call the function using the correct name. Taking all this into account, we can add function name into the error message and provide recommendations to add the system message to improve the auto-recovery mechanism. Pros: - More models can auto-recover from the error. Cons: - The auto-recovery mechanism may not work for all AI models. Possible implementation: ```csharp // The caller code var chatHistory = new ChatHistory(); chatHistory.AddSystemMessage("You can call tools. If a tool call failed, correct yourself."); chatHistory.AddUserMessage(""); // In function calls processor if (!checkIfFunctionAdvertised(functionCall)) { // errorMessage = "Error: Function call request for a function that wasn't defined."; errorMessage = $"Error: Function call request for the function that wasn't defined - {functionCall.FunctionName}."; return false; } ``` ### Option 6: Remove Disallowed Characters from the Function Name This option proposes addressing Issue 2 by removing disallowed characters from the function FQN when returning the error message to the AI model. This change will prevent the request to the AI model from failing with the exception: _"Invalid messages[3].tool_calls[0].function.name: string does not match pattern. Expected a string that matches the pattern `^[a-zA-Z0-9_-]+$`"_. Pros: - It will eliminate Issue 2 preventing AI model from auto-recovering from the error. Possible implementation: ```csharp // In AI connectors var fqn = FunctionName.ToFullyQualifiedName(callRequest.FunctionName, callRequest.PluginName, OpenAIFunction.NameSeparator); // Replace all disallowed characters with an underscore. fqn = Regex.Replace(fqn, "[^a-zA-Z0-9_-]", "_"); toolCalls.Add(ChatToolCall.CreateFunctionToolCall(callRequest.Id, fqn, BinaryData.FromString(argument ?? string.Empty))); ``` ## Decision Outcome It was decided to start with the options that don't require changes to the public API surface - Options 5 and 6 and proceed with others later if needed, after evaluating the impact of the two applied options. ================================================ FILE: docs/decisions/0064-hybrid-model-orchestration.md ================================================ --- status: accepted contact: sergeymenshykh date: 2025-02-05 deciders: dmytrostruk, markwallace, rbarreto, sergeymenshykh, westey-m, --- # Hybrid Model Orchestration ## Context and Problem Statement Taking into account the constantly emerging and improving local and cloud-based models, in addition to the growing demand for utilizing local AI models running on local devices' NPUs, AI powered applications need to be able to effectively and seamlessly leverage both local and cloud models for inference to achieve the best AI user experience. ## Decision Drivers 1. The model orchestration layer should be simple and extensible. 2. The model orchestration layer client code should not be aware of or deal with the underlying complexities. 3. The model orchestration layer should allow for different strategies for selecting the best model(s) for the task at hand. ## Considered Implementation Options The following options consider a few ways to implement the model orchestration layer. ### Option 1: IChatClient implementation per orchestration strategy This option presents a simple and straightforward approach to implementing the model orchestration layer. Each strategy is implemented as a separate implementation of the IChatClient interface. For example, a fallback strategy that uses the first configured chat client for inference and falls back to the next one if the AI model is not available may be implemented as follows: ```csharp public sealed class FallbackChatClient : IChatClient { private readonly IChatClient[] _clients; public FallbackChatClient(params IChatClient[] clients) { this._clients = clients; } public Task CompleteAsync(IList chatMessages, ChatOptions? options = null, CancellationToken cancellationToken = default) { foreach (var client in this._clients) { try { return client.CompleteAsync(chatMessages, options, cancellationToken); } catch (HttpRequestException ex) { if (ex.StatusCode >= 500) { // Try the next client continue; } throw; } } } public IAsyncEnumerable CompleteStreamingAsync(IList chatMessages, ChatOptions? options = null, CancellationToken cancellationToken = default) { ... } public void Dispose() { /*We can't dispose clients here because they can be used up the stack*/ } public ChatClientMetadata Metadata => new ChatClientMetadata(); public object? GetService(Type serviceType, object? serviceKey = null) => null; } ``` Other orchestration strategies, such as latency-based or token-based strategies, can be implemented in a similar way: a class that implements the IChatClient interface and the corresponding chat client selection strategy. Pros: - Does not require any new abstraction. - Simple and straightforward implementation. - Can be sufficient for most use cases. ### Option 2: HybridChatClient class with chat completion handler(s) per orchestration strategy This option introduces a HybridChatClient class that implements the IChatClient interface and delegates the selection routine to a provided handler represented by the abstract ChatCompletionHandler class: ```csharp public sealed class HybridChatClient : IChatClient { private readonly IChatClient[] _chatClients; private readonly ChatCompletionHandler _handler; private readonly Kernel? _kernel; public HybridChatClient(IChatClient[] chatClients, ChatCompletionHandler handler, Kernel? kernel = null) { this._chatClients = chatClients; this._handler = handler; this._kernel = kernel; } public Task CompleteAsync(IList chatMessages, ChatOptions? options = null, CancellationToken cancellationToken = default) { return this._handler.CompleteAsync( new ChatCompletionHandlerContext { ChatMessages = chatMessages, Options = options, ChatClients = this._chatClients.ToDictionary(c => c, c => (CompletionContext?)null), Kernel = this._kernel, }, cancellationToken); } public IAsyncEnumerable CompleteStreamingAsync(IList chatMessages, ChatOptions? options = null, CancellationToken cancellationToken = default) { ... } ... } public abstract class ChatCompletionHandler { public abstract Task CompleteAsync(ChatCompletionHandlerContext context, CancellationToken cancellationToken = default); public abstract IAsyncEnumerable CompleteStreamingAsync(ChatCompletionHandlerContext context, CancellationToken cancellationToken = default); } ``` The HybridChatClient class passes all the necessary information to the handler via the ChatCompletionHandlerContext class, which contains the list of chat clients, chat messages, options, and Kernel instance. ```csharp public class ChatCompletionHandlerContext { public IDictionary ChatClients { get; init; } public IList ChatMessages { get; init; } public ChatOptions? Options { get; init; } public Kernel? Kernel { get; init; } } ``` The fallback strategy shown in the previous option can be implemented as the following handler: ```csharp public class FallbackChatCompletionHandler : ChatCompletionHandler { public override async Task CompleteAsync(ChatCompletionHandlerContext context, CancellationToken cancellationToken = default) { for (int i = 0; i < context.ChatClients.Count; i++) { var chatClient = context.ChatClients.ElementAt(i).Key; try { return client.CompleteAsync(chatMessages, options, cancellationToken); } catch (HttpRequestException ex) { if (ex.StatusCode >= 500) { // Try the next client continue; } throw; } } throw new InvalidOperationException("No client provided for chat completion."); } public override async IAsyncEnumerable CompleteStreamingAsync(ChatCompletionHandlerContext context, CancellationToken cancellationToken = default) { ... } } ``` and the caller code would look like this: ```csharp IChatClient onnxChatClient = new OnnxChatClient(...); IChatClient openAIChatClient = new OpenAIChatClient(...); // Tries the first client and falls back to the next one if the first one fails FallbackChatCompletionHandler handler = new FallbackChatCompletionHandler(...); IChatClient hybridChatClient = new HybridChatClient([onnxChatClient, openAIChatClient], handler); ... var result = await hybridChatClient.CompleteAsync("Do I need an umbrella?", ...); ``` The handlers can be chained to create more complex scenarios, where a handler performs some preprocessing and then delegates the call to another handler with an augmented chat clients list. For example, the first handler identifies that a cloud model has requested access to sensitive data and delegates the call handling to local models to process it. ```csharp IChatClient onnxChatClient = new OnnxChatClient(...); IChatClient llamaChatClient = new LlamaChatClient(...); IChatClient openAIChatClient = new OpenAIChatClient(...); // Tries the first client and falls back to the next one if the first one fails FallbackChatCompletionHandler fallbackHandler = new FallbackChatCompletionHandler(...); // Check if the request contains sensitive data, identifies the client(s) allowed to work with the sensitive data, and delegates the call handling to the next handler. SensitiveDataHandler sensitiveDataHandler = new SensitiveDataHandler(fallbackHandler); IChatClient hybridChatClient = new HybridChatClient(new[] { onnxChatClient, llamaChatClient, openAIChatClient }, sensitiveDataHandler); var result = await hybridChatClient.CompleteAsync("Do I need an umbrella?", ...); ``` Examples of complex orchestration scenarios: | First Handler | Second Handler | Scenario Description | |---------------------------------------|--------------------------------|---------------------------------------------------------------------------| | InputTokenThresholdEvaluationHandler | FastestChatCompletionHandler | Identifies models based on the prompt's input token size and each model's min/max token capacity, then returns the fastest model's response. | | InputTokenThresholdEvaluationHandler | RelevancyChatCompletionHandler | Identifies models based on the prompt's input token size and each model's min/max token capacity, then returns the most relevant response. | | InputTokenThresholdEvaluationHandler | FallbackChatCompletionHandler | Identifies models based on the prompt's input token size and each model's min/max token capacity, then returns the first available model's response. | | SensitiveDataRoutingHandler | FastestChatCompletionHandler | Identifies models based on data sensitivity, then returns the fastest model's response. | | SensitiveDataRoutingHandler | RelevancyChatCompletionHandler | Identifies models based on data sensitivity, then returns the most relevant response. | | SensitiveDataRoutingHandler | FallbackChatCompletionHandler | Identifies models based on data sensitivity, then returns the first available model's response. | Pros: - Allows reusing same handlers to create various composite orchestration strategies. Cons: - Requires new abstractions and components than the previous option: context classes and code for handling the next handler.
POC demonstrating this option can be found [here](https://github.com/microsoft/semantic-kernel/pull/10412). ### Option 3: Implementing existing IAIServiceSelector interface. The Semantic Kernel has a mechanism that allows for the dynamic selection of AI services: ```csharp public interface IAIServiceSelector { bool TrySelectAIService( Kernel kernel, KernelFunction function, KernelArguments arguments, [NotNullWhen(true)] out T? service, out PromptExecutionSettings? serviceSettings) where T : class, IAIService; } ``` However, this mechanism requires specific context - the kernel, function, and arguments which may not always be available. Additionally, it only works with implementations of the IAIService interface, which may not be compatible with all AI services, such as those in Microsoft.Extensions.AI that implement the IChatClient interface. Furthermore, this mechanism cannot be used in orchestration scenarios where an AI service needs to be prompted first to determine its availability, latency, etc. For example, to check if an AI service is available, the selector would need to send chat messages with options to the service. It should then return the completion if the service is available, or fallback to another service if it is not. Given that the TrySelectAIService method does not accept a list of chat messages or options, it is impossible to send chat messages using this method. Even if it were possible, the consumer code would have to resend the same chat messages to the selected service to obtain a completion, as the selector does not return the completion itself. Additionally, the TrySelectAIService method is synchronous, making it difficult to send chat messages without using synchronous code, which is generally discouraged. Looking at the above, it is clear that the IAIServiceSelector interface is not suitable for the hybrid orchestration of AI services since it was designed for a different purpose: to synchronously select an instance of an AI service based on SK context and service metadata without taking the results of completion and streamed completion methods into account. Pros: - Reuses the existing mechanism for AI service selection. Cons: - Not suitable for all AI services. - Requires context that may not be available in all scenarios. - Consumer code must be aware of the IAIServiceSelector interface instead of simply using the IChatClient interface. - Synchronous method. ## Decision Outcome Chosen option: Option 1 because it does not require any new abstraction; its simplicity and straightforwardness are sufficient for most use cases. Option 2 can be considered in the future if more complex orchestration scenarios are required. ================================================ FILE: docs/decisions/0065-realtime-api-clients.md ================================================ --- # These are optional elements. Feel free to remove any of them. status: proposed contact: eavanvalkenburg date: 2025-01-31 deciders: eavanvalkenburg, markwallace, alliscode, sphenry consulted: westey-m, rbarreto, alliscode, markwallace, sergeymenshykh, moonbox3 informed: taochenosu, dmytrostruk --- # Multi-modal Realtime API Clients ## Context and Problem Statement Multiple model providers are starting to enable realtime voice-to-voice or even multi-modal, realtime, two-way communication with their models, this includes OpenAI with their [Realtime API][openai-realtime-api] and [Google Gemini][google-gemini]. These API's promise some very interesting new ways of using LLM's for different scenario's, which we want to enable with Semantic Kernel. The key feature that Semantic Kernel brings into this system is the ability to (re)use Semantic Kernel function as tools with these API's. There are also options for Google to use video and images as input, this will likely not be implemented first, but the abstraction should be able to deal with it. > [!IMPORTANT] > Both the OpenAI and Google realtime api's are in preview/beta, this means there might be breaking changes in the way they work coming in the future, therefore the clients built to support these API's are going to be experimental until the API's stabilize. At this time, the protocols that these API's use are Websockets and WebRTC. In both cases there are events being sent to and from the service, some events contain content, text, audio, or video (so far only sending, not receiving), while some events are "control" events, like content created, function call requested, etc. Sending events include, sending content, either voice, text or function call output, or events, like committing the input audio and requesting a response. ### Websocket Websocket has been around for a while and is a well known technology, it is a full-duplex communication protocol over a single, long-lived connection. It is used for sending and receiving messages between client and server in real-time. Each event can contain a message, which might contain a content item, or a control event. Audio is sent as a base64 encoded string in a event. ### WebRTC WebRTC is a Mozilla project that provides web browsers and mobile applications with real-time communication via simple APIs. It allows audio and video communication to work inside web pages and other applications by allowing direct peer-to-peer communication, eliminating the need to install plugins or download native apps. It is used for sending and receiving audio and video streams, and can be used for sending (data-)messages as well. The big difference compared to websockets is that it explicitly create a channel for audio and video, and a separate channel for "data", which are events and in this space that contains all non-AV content, text, function calls, function results and control events, like errors or acknowledgements. ### Event types (Websocket and partially WebRTC) #### Client side events: | **Content/Control event** | **Event Description** | **OpenAI Event** | **Google Event** | | ------------------------- | --------------------------------- | ---------------------------- | ---------------------------------- | | Control | Configure session | `session.update` | `BidiGenerateContentSetup` | | Content | Send voice input | `input_audio_buffer.append` | `BidiGenerateContentRealtimeInput` | | Control | Commit input and request response | `input_audio_buffer.commit` | `-` | | Control | Clean audio input buffer | `input_audio_buffer.clear` | `-` | | Content | Send text input | `conversation.item.create` | `BidiGenerateContentClientContent` | | Control | Interrupt audio | `conversation.item.truncate` | `-` | | Control | Delete content | `conversation.item.delete` | `-` | | Control | Respond to function call request | `conversation.item.create` | `BidiGenerateContentToolResponse` | | Control | Ask for response | `response.create` | `-` | | Control | Cancel response | `response.cancel` | `-` | #### Server side events: | **Content/Control event** | **Event Description** | **OpenAI Event** | **Google Event** | | ------------------------- | -------------------------------------- | ------------------------------------------------------- | ----------------------------------------- | | Control | Error | `error` | `-` | | Control | Session created | `session.created` | `BidiGenerateContentSetupComplete` | | Control | Session updated | `session.updated` | `BidiGenerateContentSetupComplete` | | Control | Conversation created | `conversation.created` | `-` | | Control | Input audio buffer committed | `input_audio_buffer.committed` | `-` | | Control | Input audio buffer cleared | `input_audio_buffer.cleared` | `-` | | Control | Input audio buffer speech started | `input_audio_buffer.speech_started` | `-` | | Control | Input audio buffer speech stopped | `input_audio_buffer.speech_stopped` | `-` | | Content | Conversation item created | `conversation.item.created` | `-` | | Content | Input audio transcription completed | `conversation.item.input_audio_transcription.completed` | | | Content | Input audio transcription failed | `conversation.item.input_audio_transcription.failed` | | | Control | Conversation item truncated | `conversation.item.truncated` | `-` | | Control | Conversation item deleted | `conversation.item.deleted` | `-` | | Control | Response created | `response.created` | `-` | | Control | Response done | `response.done` | `-` | | Content | Response output item added | `response.output_item.added` | `-` | | Content | Response output item done | `response.output_item.done` | `-` | | Content | Response content part added | `response.content_part.added` | `-` | | Content | Response content part done | `response.content_part.done` | `-` | | Content | Response text delta | `response.text.delta` | `BidiGenerateContentServerContent` | | Content | Response text done | `response.text.done` | `-` | | Content | Response audio transcript delta | `response.audio_transcript.delta` | `BidiGenerateContentServerContent` | | Content | Response audio transcript done | `response.audio_transcript.done` | `-` | | Content | Response audio delta | `response.audio.delta` | `BidiGenerateContentServerContent` | | Content | Response audio done | `response.audio.done` | `-` | | Content | Response function call arguments delta | `response.function_call_arguments.delta` | `BidiGenerateContentToolCall` | | Content | Response function call arguments done | `response.function_call_arguments.done` | `-` | | Control | Function call cancelled | `-` | `BidiGenerateContentToolCallCancellation` | | Control | Rate limits updated | `rate_limits.updated` | `-` | ## Overall Decision Drivers - Abstract away the underlying protocols, so that developers can build applications that implement whatever protocol they want to support, without having to change the client code when changing models or protocols. - There are some limitations expected here as i.e. WebRTC requires different information at session create time than websockets. - Simple programming model that is likely able to handle future realtime api's and the evolution of the existing ones. - Whenever possible we transform incoming content into Semantic Kernel content, but surface everything, so it's extensible for developers and in the future. There are multiple areas where we need to make decisions, these are: - Content and Events - Programming model - Audio speaker/microphone handling - Interface design and naming # Content and Events ## Considered Options - Content and Events Both the sending and receiving side of these integrations need to decide how to deal with the events. 1. Treat content separate from control 1. Treat everything as content items 1. Treat everything as events ### 1. Treat content separate from control This would mean there are two mechanisms in the clients, one deals with content, and one with control events. - Pro: - strongly typed responses for known content - easy to use as the main interactions are clear with familiar SK content types, the rest goes through a separate mechanism - Con: - new content support requires updates in the codebase and can be considered breaking (potentially sending additional types back) - additional complexity in dealing with two streams of data - some items, such as Function calls can be considered both content and control, control when doing auto-function calling, but content when the developer wants to deal with it themselves ### 2. Treat everything as content items This would mean that all events are turned into Semantic Kernel content items, and would also mean that we need to define additional content types for the control events. - Pro: - everything is a content item, so it's easy to deal with - Con: - new content type needed for control events ### 3. Treat everything as events This would introduce events, each event has a type, those can be core content types, like audio, video, image, text, function call or function response, as well as a generic event for control events without content. Each event has a SK type, from above as well as a service_event_type field that contains the event type from the service. Finally the event has a content field, which corresponds to the type, and for the generic event contains the raw event from the service. - Pro: - no transformation needed for service events - easy to maintain and extend - Con: - new concept introduced - might be confusing to have contents with and without SK types ## Decision Outcome - Content and Events Chosen option: 3 Treat Everything as Events This option was chosen to allow abstraction away from the raw events, while still allowing the developer to access the raw events if needed. A base event type is added called `RealtimeEvent`, this has three fields, a `event_type`, `service_event_type` and `service_event`. It then has four subclasses, one each for audio, text, function call and function result. When a known piece of content has come in, it will be parsed into a SK content type and added, this content should also have the raw event in the inner_content, so events are then stored twice, once in the event, once in the content, this is by design so that if the developer needs to access the raw event, they can do so easily even when they remove the event layer. It might also be possible that a single event from the service contains multiple content items, for instance a response might contain both text and audio, in that case multiple events will be emitted. In principle a event has to be handled once, so if there is event that is parsable only the subtype is returned, since it has all the same information as the `RealtimeEvent` this will allow developers to trigger directly off the service_event_type and service_event if they don't want to use the abstracted types. ```python RealtimeEvent( event_type="service", # single default value in order to discriminate easily service_event_type="conversation.item.create", # optional service_event: { ... } # optional, because some events do not have content. ) ``` ```python RealtimeAudioEvent(RealtimeEvent)( event_type="audio", # single default value in order to discriminate easily service_event_type="response.audio.delta", # optional service_event: { ... } audio: AudioContent(...) ) ``` ```python RealtimeTextEvent(RealtimeEvent)( event_type="text", # single default value in order to discriminate easily service_event_type="response.text.delta", # optional service_event: { ... } text: TextContent(...) ) ``` ```python RealtimeFunctionCallEvent(RealtimeEvent)( event_type="function_call", # single default value in order to discriminate easily service_event_type="response.function_call_arguments.delta", # optional service_event: { ... } function_call: FunctionCallContent(...) ) ``` ```python RealtimeFunctionResultEvent(RealtimeEvent)( event_type="function_result", # single default value in order to discriminate easily service_event_type="response.output_item.added", # optional service_event: { ... } function_result: FunctionResultContent(...) ) ``` ```python RealtimeImageEvent(RealtimeEvent)( event_type="image", # single default value in order to discriminate easily service_event_type="response.image.delta", # optional service_event: { ... } image: ImageContent(...) ) ``` This allows you to easily do pattern matching on the event_type, or use the service_event_type to filter on the specific event type for service events, or match on the type of the event and get the SK contents from it. There might be other abstracted types needed at some point, for instance errors, or session updates, but since the current two services have no agreement on the existence of these events and their structure, it is better to wait until there is a need for them. ### Rejected ideas #### ID Handling One open item is whether to include a extra field in these types for tracking related pieces, however this becomes problematic because the way those are generated differs per service and is quite complex, for instance the OpenAI API returns a piece of audio transcript with the following ids: - `event_id`: the unique id of the event - `response_id`: the id of the response - `item_id`: the id of the item - `output_index`: the index of the output item in the response - `content_index`: The index of the content part in the item's content array For an example of the events emitted by OpenAI see the [details](#background-info) below. While Google has ID's only in some content items, like function calls, but not for audio or text content. Since the id's are always available through the raw event (either as inner_content or as .event), it is not necessary to add them to the content types, and it would make the content types more complex and harder to reuse across services. #### Wrapping content in a (Streaming)ChatMessageContent Wrapping content in a `(Streaming)ChatMessageContent` first, this will add another layer of complexity and since a CMC can contain multiple items, to access audio, would look like this: `service_event.content.items[0].audio.data`, which is not as clear as `service_event.audio.data`. # Programming model ## Considered Options - Programming model The programming model for the clients needs to be simple and easy to use, while also being able to handle the complexity of the realtime api's. _In this section we will refer to events for both content and events, regardless of the decision made in the previous section._ This is mostly about the receiving side of things, sending is much simpler. 1. Event handlers, developers register handlers for specific events, and the client calls these handlers when an event is received - 1a: Single event handlers, where each event is passed to the handler - 1b: Multiple event handlers, where each event type has its own handler(s) 2. Event buffers/queues that are exposed to the developer, start sending and start receiving methods, that just initiate the sending and receiving of events and thereby the filling of the buffers 3. AsyncGenerator that yields Events ### 1. Event handlers, developers register handlers for specific events, and the client calls these handlers when an event is received This would mean that the client would have a mechanism to register event handlers, and the integration would call these handlers when an event is received. For sending events, a function would be created that sends the event to the service. - Pro: - no need to deal with complex things like async generators and easier to keep track of what events you want to respond to - Con: - can become cumbersome, and in 1b would require updates to support new events - things like ordering (which event handler is called first) are unclear to the developer ### 2. Event buffers/queues that are exposed to the developer, start sending and start receiving methods, that just initiate the sending and receiving of events and thereby the filling of the buffers This would mean that there are two queues, one for sending and one for receiving, and the developer can listen to the receiving queue and send to the sending queue. Internal things like parsing events to content types and auto-function calling are processed first, and the result is put in the queue, the content type should use inner_content to capture the full event and these might add a message to the send queue as well. - Pro: - simple to use, just start sending and start receiving - easy to understand, as queues are a well known concept - developers can just skip events they are not interested in - Con: - potentially causes audio delays because of the queueing mechanism ### 2b. Same as option 2, but with priority handling of audio content This would mean that the audio content is handled first and sent to a callback directly so that the developer can play it or send it onward as soon as possible, and then all other events are processed (like text, function calls, etc) and put in the queue. - Pro: - mitigates audio delays - easy to understand, as queues are a well known concept - developers can just skip events they are not interested in - Con: - Two separate mechanisms used for audio content and events ### 3. AsyncGenerator that yields Events This would mean that the clients implement a function that yields events, and the developer can loop through it and deal with events as they come. - Pro: - easy to use, just loop through the events - easy to understand, as async generators are a well known concept - developers can just skip events they are not interested in - Con: - potentially causes audio delays because of the async nature of the generator - lots of events types mean a large single set of code to handle it all ### 3b. Same as option 3, but with priority handling of audio content This would mean that the audio content is handled first and sent to a callback directly so that the developer can play it or send it onward as soon as possible, and then all other events are parsed and yielded. - Pro: - mitigates audio delays - easy to understand, as async generators are a well known concept - Con: - Two separate mechanisms used for audio content and events ## Decision Outcome - Programming model Chosen option: 3b AsyncGenerator that yields Events combined with priority handling of audio content through a callback This makes the programming model very easy, a minimal setup that should work for every service and protocol would look like this: ```python async for event in realtime_client.start_streaming(): match event: case AudioEvent(): await audio_player.add_audio(event.audio) case TextEvent(): print(event.text.text) ``` # Audio speaker/microphone handling ## Considered Options - Audio speaker/microphone handling 1. Create abstraction in SK for audio handlers, that can be passed into the realtime client to record and play audio 2. Send and receive AudioContent to the client, and let the client handle the audio recording and playing ### 1. Create abstraction in SK for audio handlers, that can be passed into the realtime client to record and play audio This would mean that the client would have a mechanism to register audio handlers, and the integration would call these handlers when audio is received or needs to be sent. A additional abstraction for this would have to be created in Semantic Kernel (or potentially taken from a standard). - Pro: - simple/local audio handlers can be shipped with SK making it easy to use - extensible by third parties to integrate into other systems (like Azure Communications Service) - could mitigate buffer issues by prioritizing audio content being sent to the handlers - Con: - extra code in SK that needs to be maintained, potentially relying on third party code - audio drivers can be platform specific, so this might not work well or at all on all platforms ### 2. Send and receive AudioContent to the client, and let the client handle the audio recording and playing This would mean that the client would receive AudioContent items, and would have to deal with them itself, including recording and playing the audio. - Pro: - no extra code in SK that needs to be maintained - Con: - extra burden on the developer to deal with the audio - harder to get started with ## Decision Outcome - Audio speaker/microphone handling Chosen option: Option 2: there are vast difference in audio format, frame duration, sample rate and other audio settings, that a default that works *always* is likely not feasible, and the developer will have to deal with this anyway, so it's better to let them deal with it from the start, we will add sample audio handlers to the samples to still allow people to get started with ease. # Interface design The following functionalities will need to be supported: - create session - update session - close session - listen for/receive events - send events ## Considered Options - Interface design 1. Use a single class for everything 2. Split the service class from a session class. ### 1. Use a single class for everything Each implementation would have to implements all of the above methods. This means that non-protocol specific elements are in the same class as the protocol specific elements and will lead to code duplication between them. ### 2. Split the service class from a session class. Two interfaces are created: - Service: create session, update session, delete session, maybe list sessions? - Session: listen for/receive events, send events, update session, close session Currently neither the google or the openai api's support restarting sessions, so the advantage of splitting is mostly a implementation question but will not add any benefits to the developer. This means that the resultant split will actually be far simpler: - Service: create session - Session: listen for/receive events, send events, update session, close session ## Naming The send and listen/receive methods need to be clear in the way their are named and this can become confusing when dealing with these api's. The following options are considered: Options for sending events to the service from your code: - google uses .send in their client. - OpenAI uses .send in their client as well - send or send_message is used in other clients, like Azure Communication Services Options for listening for events from the service in your code: - google uses .receive in their client. - openai uses .recv in their client. - others use receive or receive_messages in their clients. ### Decision Outcome - Interface design Chosen option: Use a single class for everything Chosen for send and receive as verbs. This means that the interface will look like this: ```python class RealtimeClient: async def create_session(self, chat_history: ChatHistory, settings: PromptExecutionSettings, **kwargs) -> None: ... async def update_session(self, chat_history: ChatHistory, settings: PromptExecutionSettings, **kwargs) -> None: ... async def close_session(self, **kwargs) -> None: ... async def receive(self, chat_history: ChatHistory, **kwargs) -> AsyncGenerator[RealtimeEvent, None]: ... async def send(self, event: RealtimeEvent) -> None: ... ``` In most cases, `create_session` should call `update_session` with the same parameters, since update session can also be done separately later on with the same inputs. For Python a default `__aenter__` and `__aexit__` method should be added to the class, so it can be used in a `async with` statement, which calls create_session and close_session respectively. It is advisable, but not required, to implement the send method through a buffer/queue so that events can be 'sent' before the sessions has been established without losing them or raising exceptions, since the session creation might take a few seconds and in that time a single send call would either block the application or throw an exception. The send method should handle all events types, but it might have to handle the same thing in two ways, for instance (for the OpenAI API): ```python audio = AudioContent(...) await client.send(AudioEvent(audio=audio)) ``` should be equivalent to: ```python audio = AudioContent(...) await client.send(ServiceEvent(service_event_type='input_audio_buffer.append', service_event=audio)) ``` The first version allows one to have the exact same code for all services, while the second version is also correct and should be handled correctly as well, this once again allows for flexibility and simplicity, when audio needs to be sent to with a different event type, that is still possible in the second way, while the first uses the "default" event type for that particular service, this can for instance be used to seed the conversation with completed audio snippets from a previous session, rather then just the transcripts, the completed audio, needs to be of event type 'conversation.item.create' for OpenAI, while a streamed 'frame' of audio would be 'input_audio_buffer.append' and that would be the default to use. The developer should document which service event types are used by default for the non-ServiceEvents. ## Background info Example of events coming from a few seconds of conversation with the OpenAI Realtime:

Feel free to remove any of them. status: proposed contact: rogerbarreto date: 2025-02-11 deciders: markwallace, sergey, dmytro, weslie, evan, shawn --- # Structured Concepts ## Context and Problem Statement Currently, the Concepts project has grown considerably, with many samples that do not consistently follow a structured pattern or guideline. A revisit of our sample patterns in favor of key drivers needs to be considered. This ADR starts by suggesting rules we might follow to keep new concepts following good patterns that make them easy to comprehend, find, and descriptive. The Semantic Kernel audience can vary greatly—from pro-devs, beginners, and non-developers. We understand that making sure examples and guidelines are as straightforward as possible is of our highest priority. ### Decision Drivers - Easy to find - Easy to understand - Easy to set up - Easy to execute The above drivers focus on ensuring that we follow good practices, patterns, and a structure for our samples, guaranteeing proper documentation, simplification of code for easier understanding, as well as the usage of descriptive classes, methods, and variables. We also understand how important it is to ensure our samples are copy-and-paste friendly (work "as is"), being as frictionless as possible. ## Solution Applying a set of easy-to-follow guidelines and good practices to the Concepts project will help maintain a good collection of samples that are easy to find, understand, set up, and execute. This guideline will be applied for any maintenance or newly added samples to the Concepts project. The contents may be added to a new CONTRIBUTING.md file in the Concepts project. > [!NOTE] > Rules/Conventions that are already ensured by analyzers are not mentioned in the list below. ## Rules ### Sample Classes Each class in the Concepts project MUST have an xmldoc description of what is being sampled, with clear information on what is being sampled. ✅ DO have xmldoc description detailing what is being sampled. ✅ DO have xmldoc remarks for the required packages. ✅ CONSIDER using xmldoc remarks for additional information. ❌ AVOID using generic descriptions. ✅ DO name classes with at least two words, separated by an underscore `First_Second_Third_Fourth`. ✅ DO name classes with the `First` word reserved for the given concept or provider name (e.g., `OpenAI_ChatCompletion`). When the file has examples for a specific ``, it should start with the `` as the first word. `` here can also include runtime, platform, protocol, or service names. ✅ CONSIDER naming `Second` and later words to create the best grouping for examples, e.g., `AzureAISearch_VectorStore_ConsumeFromMemoryStore`. ✅ CONSIDER naming when there are more than two words, using a left-to-right grouping, e.g., `AzureAISearch_VectorStore_ConsumeFromMemoryStore`: for `AzureAISearch` within `VectorStore` grouping, there's a `ConsumeFromMemoryStore` example. ### Sample Methods ✅ DO have an xmldoc description detailing what is being sampled when the class has more than one sample method. ✅ DO have descriptive method names limited to five words, separated by an underscore, e.g., `[Fact] public Task First_Second_Third_Fourth_Fifth()`. ❌ DO NOT use `Async` suffix for Tasks. ❌ AVOID using parameters in the method signature. ❌ DO NOT have more than 3 samples in a single class. Split the samples into multiple classes when needed. ### Code ✅ DO keep code clear and concise. For the most part, variable names and APIs should be self-explanatory. ✅ CONSIDER commenting the code for large sample methods. ❌ DO NOT use acronyms or short names for variables, methods, or classes. ❌ AVOID any references to common helper classes or methods that are not part of the sample file, e.g., avoid methods like `BaseTest.OutputLastMessage`. ## Decision Outcome TBD ================================================ FILE: docs/decisions/0067-hybrid-search.md ================================================ --- # These are optional elements.

Hybrid search typically results in higher quality search results, and therefore the ability to do Hybrid search via VectorStore abstractions is an important feature to add. The way in which Hybrid search is supported varies by database. The two most common ways of supporting hybrid search is: 1. Using dense vector search and keyword/fulltext search in parallel, and then combining the results. 1. Using dense vector search and sparse vector search in parallel, and then combining the results. Sparse vectors are different from dense vectors in that they typically have many more dimensions, but with many of the dimensions being zero. Sparse vectors, when used with text search, have a dimension for each word/token in a vocabulary, with the value indicating the importance of the word in the source text. The more common the word in a specific chunk of text, and the less common the word is in the corpus, the higher the value in the sparse vector. There are various mechanisms for generating sparse vectors, such as - [TF-IDF](https://en.wikipedia.org/wiki/Tf%E2%80%93idf) - [SPLADE](https://www.pinecone.io/learn/splade/) - [BGE-m3 sparse embedding model](https://huggingface.co/BAAI/bge-m3). - [pinecone-sparse-english-v0](https://docs.pinecone.io/models/pinecone-sparse-english-v0) While these are supported well in Python, they are not well supported in .net today. Adding support for generating sparse vectors is out of scope of this ADR. More background information: - [Background article from Qdrant about using sparse vectors for Hybrid Search](https://qdrant.tech/articles/sparse-vectors) - [TF-IDF explainer for beginners](https://medium.com/@coldstart_coder/understanding-and-implementing-tf-idf-in-python-a325d1301484) ML.Net contains an implementation of TF-IDF that could be used to generate sparse vectors in .net.

Filter { get; init; } public int Top { get; init; } = 3; public int Skip { get; init; } = 0; public bool IncludeVectors { get; init; } = false; public bool IncludeTotalCount { get; init; } = false; } ``` ## Decision Drivers - Support for generating sparse vectors is required to make sparse vector based hybrid search viable. - Multiple vectors per record scenarios need to be supported. - No database in our evaluation set have been identified as supporting converting text to sparse vectors in the database on upsert and storing those sparse vectors in a retrievable field. Of course some of these DBs may use sparse vectors internally to implement keyword search, without exposing them to the caller. ## Scoping Considered Options ### 1. Keyword Hybrid Search Only Only implement KeywordVectorizedHybridSearch & KeywordVectorizableTextHybridSearch for now, until we can add support for generating sparse vectors. ### 2. Keyword and SparseVectorized Hybrid Search Implement KeywordVectorizedHybridSearch & KeywordVectorizableTextHybridSearch but only KeywordVectorizableTextHybridSearch, since no database in our evaluation set supports generating sparse vectors in the database. This will require us to produce code that can generate sparse vectors from text. ### 3. All abovementioned Hybrid Search Create all four interfaces and implement an implementation of SparseVectorizableTextHybridSearch that generates the sparse vector in the client code. This will require us to produce code that can generate sparse vectors from text. ### 4. Generalized Hybrid Search Some databases support a more generalized version of hybrid search, where you can take two (or sometimes more) searches of any type and combine the results of these using your chosen fusion method. You can implement Vector + Keyword search using this more generalized search. For databases that support only Vector + Keyword hybrid search though, it is not possible to implement the generalized hybrid search on top of those databases. ## PropertyName Naming Considered Options ### 1. Explicit Dense naming DenseVectorPropertyName SparseVectorPropertyName DenseVectorPropertyName FullTextPropertyName - Pros: This is more explicit, considering that there are also sparse vectors involved. - Cons: It is inconsistent with the naming in the non-hybrid vector search. ### 2. Implicit Dense naming VectorPropertyName SparseVectorPropertyName VectorPropertyName FullTextPropertyName - Pros: This is consistent with the naming in the non-hybrid vector search. - Cons: It is internally inconsistent, i.e. we have sparse vector, but for dense it's just vector. ## Keyword splitting Considered Options ### 1. Accept Split keywords in interface Accept an ICollection of string where each value is a separate keyword. A version that takes a single keyword and calls the `ICollection` version can also be provided as an extension method. ```csharp Task> KeywordVectorizedHybridSearch( TVector vector, ICollection keywords, KeywordVectorizedHybridSearchOptions options, CancellationToken cancellationToken); ``` - Pros: Easier to use in the connector if the underlying DB requires split keywords - Pros: Only solution broadly supported, see comparison table above. ### 2. Accept single string in interface Accept a single string containing all the keywords. ```csharp Task> KeywordVectorizedHybridSearch( TVector vector, string keywords, KeywordVectorizedHybridSearchOptions options, CancellationToken cancellationToken); ``` - Pros: Easier for a user to use, since they don't need to do any keyword splitting. - Cons: We don't have the capabilities to properly sanitise the string, e.g. splitting words appropriately for the language, and potentially removing filler words. ### 3. Accept either in interface Accept either option and either combine or split the keywords in the connector as needed by the underlying db. ```csharp Task> KeywordVectorizedHybridSearch( TVector vector, ICollection keywords, KeywordVectorizedHybridSearchOptions options, CancellationToken cancellationToken); Task> KeywordVectorizedHybridSearch( TVector vector, string keywords, KeywordVectorizedHybridSearchOptions options, CancellationToken cancellationToken); ``` - Pros: Easier for a user to use, since they can pick whichever suits them better - Cons: We have to still convert to/from the internal presentation by either combining keywords or splitting them. - Cons: We don't have the capabilities to properly sanitise the single string, e.g. splitting words appropriately for the language, and potentially removing filler words. ### 4. Accept either in interface but throw for not supported Accept either option but throw for the one not supported by the underlying DB. - Pros: Easier for us to implement. - Cons: Harder for users to use. ### 5. Separate interfaces for each Create a separate interface for the Enumerable and single string options, and only implement the one that is supported by the underlying system for each db. - Pros: Easier for us to implement. - Cons: Harder for users to use. ## Full text search index mandatory configuration Considered Options Cosmos DB NoSQL requires a language to be specified when creating a full text search index. Other DBs have optional values that can be set. ### 1. Pass option in via collection options This option does the minimum by just adding a language option to the collection's options class. This language would then be used for all full text search indexes created by the collection. - Pros: Simplest to implement - Cons: Doesn't allow multiple languages to be used for different fields in one record - Cons: Doesn't add support for all full text search options for all dbs ### 2. Add extensions for RecordDefinition and data model Attributes Add a property bag to the VectorStoreRecordProperty allowing database specific metadata to be provided. Add an abstract base attribute that can be inherited from that allows extra metadata to be added to the data model, where each database has their own attributes to specify their settings, with a method to convert the contents to the property bag required by VectorStoreRecordProperty. - Pros: Allows multiple languages to be used for different fields in one record - Pros: Allows other DBs to add their own settings via their own attributes - Cons: More work to implement ## Decision Outcome ### Scoping Chosen option "1. Keyword Hybrid Search Only", since enterprise support for generating sparse vectors is poor and without an end to end story, the value is low. ### PropertyName Naming Chosen option "2. Implicit Dense naming", since it is consistent with the existing vector search options naming. ### Keyword splitting Chosen option "1. Accept Split keywords in interface", since it is the only one with broad support amongst databases. ### Naming Options decision We agreed that our north star design would be to support the Embedding type and some form of vectorizable data (probably DataContent from MEAI) as input for both Regular search and Hybrid search. ```csharp public Task VectorSearch(Embedding embedding, VectorSearchOptions options = null, CancellationToken cancellationToken = null); public Task VectorSearch(VectorizableData vectorizableData, VectorSearchOptions options = null, CancellationToken cancellationToken = null); public Task VectorSearch(VectorizableData[] vectorizableData, VectorSearchOptions options = null, CancellationToken cancellationToken = null); public Task HybridSearch(TVector vector, VectorizableData vectorizableData, HybridSearchOptions options = null, CancellationToken cancellationToken = null); ``` We will have a single HybridSearch method name, with different overloads in future for different inputs, however there will be a single options class. The property selector for choosing the target keyword field or in future the sparse vector field will be called `AdditionalPropertyName`. While we work on getting the right data types and Embedding types to be available, we will ship the following interface. ```csharp public Task HybridSearch(TVector vector, ICollection keywords, HybridSearchOptions options = null, CancellationToken cancellationToken); ``` ================================================ FILE: docs/decisions/0068-structured-data-connector.md ================================================ --- status: proposed contact: rogerbarreto date: 2025-03-07 deciders: rogerbarreto, markwallace, dmytrostruk, westey-m, sergeymenshykh --- # Structured Data Plugin Implementation in Semantic Kernel ## Context and Problem Statement Modern AI applications often need to interact with structured data in databases while leveraging LLM capabilities. As Semantic Kernel's core focuses on AI orchestration, we need a standardized approach to integrate database operations with AI capabilities. This ADR proposes an experimental StructuredDataConnector as an initial solution for database-AI integration, focusing on basic CRUD operations and simple querying. ## Decision Drivers - Need for initial database integration pattern with SK - Requirement for basic composable AI and database operations - Alignment with SK's plugin architecture - Ability to validate the approach through real-world usage - Support for strongly-typed schema validation - Consistent JSON formatting for AI interactions ## Key Benefits 1. **Plugin-Based Architecture** - Aligns with SK's plugin architecture - Supports extension methods for common operations - Leverages KernelJsonSchema for type safety 2. **Structured Data Operations** - CRUD operations with schema validation - JSON-based interactions with proper formatting - Type-safe database operations 3. **Integration Features** - Built-in JSON schema generation - Automatic type conversion - Pretty-printed JSON for better AI interactions ## Implementation Details The implementation includes: 1. Core Components: - `StructuredDataService`: Base service for database operations - `StructuredDataServiceExtensions`: Extension methods for CRUD operations - `StructuredDataPluginFactory`: Factory for creating SK plugins - Integration with `KernelJsonSchema` for type validation 2. Key Features: - Automatic schema generation from entity types - Properly formatted JSON responses - Extension-based architecture for maintainability - Support for Entity Framework Core 3. Usage Example: ```csharp var service = new StructuredDataService(dbContext); var plugin = StructuredDataPluginFactory.CreateStructuredDataPlugin( service, operations: StructuredDataOperation.Default); ``` ## Decision Outcome Chosen option: TBD: 1. Provides standardized database integration 2. Leverages SK's schema validation capabilities 3. Supports proper JSON formatting for AI interactions 4. Maintains type safety through generated schemas 5. Follows established SK patterns and principles ## More Information This is an experimental approach that will evolve based on community feedback. ================================================ FILE: docs/decisions/0069-mcp.md ================================================ --- status: approved contact: eavanvalkenburg date: 2024-04-08 deciders: eavanvalkenburg, markwallace, sergeymenshykh, sphenry --- # Model Context Protocol integration ## Context and Problem Statement [MCP](https://modelcontextprotocol.io/introduction) is rapidly gaining momentum as a standard for AI model interaction, and Semantic Kernel is well-positioned to leverage this trend. By integrating MCP, we can enhance the interoperability of our platform with other AI systems and tools, making it easier for developers to build applications that utilize multiple models and services. This ADR will define the mapping of MCP concepts to Semantic Kernel concepts, this should provide a roadmap for the implementation of MCP in Semantic Kernel. Since MCP is actively being developed, this document will need to be updated as new concepts are added, or the practical implementation of the concepts changes. ## Design The first high level concept is a `server` vs a `host`. A Server makes one or more capabilities available to any host, a host uses a Client to connect to a server, and allows the application to consume the capabilities of the server. The host can be a client to multiple servers, and a server can be hosted by multiple hosts. ## Design - Semantic Kernel as a Host This means that we would like Semantic Kernel to be able to act as a host, and use the capabilities of a server. This is done by creating a plugin that uses the MCP SDK Clients to connect to a server, and exposes the capabilities of that server. ### Concept mapping - Semantic Kernel as a (MCP)Host | MCP Concept | Semantic Kernel Concept | Description | | ----------- | ---------------------- | ----------- | | [Server](https://modelcontextprotocol.io/docs/concepts/architecture) | Plugin | A server is exposed as a related set of functions, hence this maps to a plugin. | | [Resources](https://modelcontextprotocol.io/docs/concepts/resources) | Unclear | Since a resource is a very generic concept, it is likely to fit into any one SK Concept, but not all. We need to investigate this further. | | [Prompts](https://modelcontextprotocol.io/docs/concepts/prompts) | External Prompt Rendering/Function call | A prompt is a capability that the developer of a server can create to allow a user a easier entry point to utilizing that server, it can contain a single sentence, that get's filled with the defined parameters, or a can be a set of messages back and forth, simulating a chat conversation, designed to jumpstart a certain outcome. This maps to a the rendering step of a PromptTemplate, but the server does the rendering, SK would consume that. The output is to be a list of PromptMessages (roughly equivalent to a list of ChatMessageContents), this can then be sent to a LLM for a completion, but it is unclear how this should work. | | [Tools](https://modelcontextprotocol.io/docs/concepts/tools) | Function | A tool is a capability that the developer of a server can create to allow a user to utilize a certain functionality of the server. This maps to a function in Semantic Kernel, the most common way of using these is through function calling, so this maps nicely. This should include handling listChanged events. | | [Sampling](https://modelcontextprotocol.io/docs/concepts/sampling) | get_chat_message_content | Sampling is a powerful MCP feature that allows servers to request LLM completions through the client, enabling sophisticated agentic behaviors while maintaining security and privacy. In other words, it would mean that the server sends a message to the SK host and the SK host calls a LLM with it. It does require mapping between the `ModelPreferences` and other details of the message between MCP and SK `PromptExecutionSettings` and service selectors. | | [Roots](https://modelcontextprotocol.io/docs/concepts/roots) | Dependent on what context is available | Roots are a concept in MCP that define the boundaries where servers can operate. They provide a way for clients to inform servers about relevant resources and their locations, so SK should send the `roots` of the current context to the used server, it will depend on the specific context, for instance when using the FileIOPlugin for .Net this could be used. In Python we currently do not have this. | | [Transports](https://modelcontextprotocol.io/docs/concepts/transports) | Different plugin implementations | SK should support all transports, and abstract away the differences between them. This means that the plugin should be able to use any transport, and the SK host should be able to use any transport, with just configuration changes. | | [Completion](https://spec.modelcontextprotocol.io/specification/2025-03-26/server/utilities/completion/) | Unmapped | The completion for MCP is about completing the user input while typing, to auto-suggest the next character, for instance when entering a Resource URL. This is not a concept that we need to support in SK, a client built using SK can implement this. | | [Progress](https://spec.modelcontextprotocol.io/specification/2025-03-26/basic/utilities/progress/) | Unmapped | The progress for MCP is about showing the progress of a long running task, this is not a concept that we need to support in SK, a client built using SK can implement this. | ## Design - Semantic Kernel as a Server This means that we would like Semantic Kernel to be able to act as a server, and expose the capabilities of a Kernel and/or Agent to a host. ### Concept mapping - Semantic Kernel as a Server | MCP Concept | Semantic Kernel Concept | Description | | ----------- | ---------------------- | ----------- | | [Server](https://modelcontextprotocol.io/docs/concepts/architecture) | Kernel/Agent | A server is exposed as a related set of functions, so we can expose a single Kernel or a Agent as a MCP server, this can then be consumed by any compatible host. | | [Resources](https://modelcontextprotocol.io/docs/concepts/resources) | Unclear | Since a resource is a very generic concept, it is likely to fit into any one SK Concept, but not all. We need to investigate this further. | | [Prompts](https://modelcontextprotocol.io/docs/concepts/prompts) | PromptTemplate | A prompt is a capability that the developer of the SK server can create to allow a user a easier entry point to utilizing that server, it can contain a single sentence, that get's filled with the defined parameters, or a can be a set of messages back and forth, simulating a chat conversation, designed to jumpstart a certain outcome. This maps to a PromptTemplate, but the output needs to be a list of PromptMessages (roughly equivalent to a list of ChatMessageContents), so some work is needed to enable this in a generic way. In this case the client asks for the prompt, supplying a set of arguments, those are then rendered by SK and turned into a list of ChatMessageContent, and then to a list of MCP PromptMessages. | | [Tools](https://modelcontextprotocol.io/docs/concepts/tools) | Function | A tool is a capability that the developer of a server can create to allow a user to utilize a certain functionality of the server. This maps to a function in Semantic Kernel, the most common way of using these is through function calling, so this maps nicely. This should include listChanged events being emitted. | | [Sampling](https://modelcontextprotocol.io/docs/concepts/sampling) | Unclear | Sampling is a powerful MCP feature that allows servers to request LLM completions through the client, enabling sophisticated agentic behaviors while maintaining security and privacy. In other words, it would mean that a SK server renders a prompt and then asks the client to use it's LLM's to do the completion, since this is a so core to SK it probably does not need to be mapped, as this is useful mostly for MCP servers, that do not interact with LLM's themselves. | | [Roots](https://modelcontextprotocol.io/docs/concepts/roots) | Unclear | Roots are a concept in MCP that define the boundaries where servers can operate. They provide a way for clients to inform servers about relevant resources and their locations, so SK should send the `roots` of the current context to the used server, it is unclear how to map this at this time. | | [Transports](https://modelcontextprotocol.io/docs/concepts/transports) | Language specific | For python, the SDK makes sure to unify the interaction and then host those interactions in one of the transport types, so no need to specify this in SK itself. | | [Completion](https://spec.modelcontextprotocol.io/specification/2025-03-26/server/utilities/completion/) | Unmapped | The completion for MCP is about completing the user input while typing, to auto-suggest the next character, for instance when entering a Resource URL or a Prompt reference. For both it depends on what kind of support we will have for Prompt and Resources, but if we support them we should also support completions for them OOTB. | | [Logging](https://spec.modelcontextprotocol.io/specification/2025-03-26/server/utilities/logging/) | Built-in loggers | The MCP logging is a way to log the interactions between the client and the server, we should probably add logging handlers by default, that can be set and changed by the client/host. | | [Progress](https://spec.modelcontextprotocol.io/specification/2025-03-26/basic/utilities/progress/) | Unmapped | The progress for MCP is about showing the progress of a long running task, this might become interesting for Agents or Processes, that go off and do more complex long-running task, so providing updates to the client makes the experience better. Unclear how to implement this. | ================================================ FILE: docs/decisions/0070-declarative-agent-schema.md ================================================ --- # These are optional elements. Feel free to remove any of them. status: proposed contact: markwallace-microsoft date: 2025-01-17 deciders: markwallace-microsoft, bentho, crickman consulted: {list everyone whose opinions are sought (typically subject-matter experts); and with whom there is a two-way communication} informed: {list everyone who is kept up-to-date on progress; and with whom there is a one-way communication} --- # Schema for Declarative Agent Format ## Context and Problem Statement This ADR describes a schema which can be used to define an Agent which can be loaded and executed using the Semantic Kernel Agent Framework. Currently the Agent Framework uses a code first approach to allow Agents to be defined and executed. Using the schema defined by this ADR developers will be able to declaratively define an Agent and have the Semantic Kernel instantiate and execute the Agent. Here is some pseudo code to illustrate what we need to be able to do: ```csharp Kernel kernel = Kernel .CreateBuilder() .AddAzureAIClientProvider(...) .Build(); var text = """ type: azureai_agent name: AzureAIAgent description: AzureAIAgent Description instructions: AzureAIAgent Instructions model: id: gpt-4o-mini tools: - name: tool1 type: code_interpreter """; AzureAIAgentFactory factory = new(); var agent = await KernelAgentYaml.FromAgentYamlAsync(kernel, text, factory); ``` The above code represents the simplest case would work as follows: 1. The `Kernel` instance has the appropriate services e.g. an instance of `AzureAIClientProvider` when creating AzureAI agents. 2. The `KernelAgentYaml.FromAgentYamlAsync` will create one of the built-in Agent instances i.e., one of `ChatCompletionAgent`, `OpenAIAssistantsAgent`, `AzureAIAgent`. 3. The new Agent instance is initialized with it's own `Kernel` instance configured the services and tools it requires and a default initial state. Note: Consider creating just plain `Agent` instances and extending the `Agent` abstraction to contain a method which allows the Agent instance to be invoked with user input. ```csharp Kernel kernel = ... string text = EmbeddedResource.Read("MyAgent.yaml"); AgentFactory agentFactory = new AggregatorAgentFactory( new ChatCompletionAgentFactory(), new OpenAIAssistantAgentFactory(), new AzureAIAgentFactory()); var agent = KernelAgentYaml.FromAgentYamlAsync(kernel, text, factory);; ``` The above example shows how different Agent types are supported. **Note:** 1. Markdown with YAML front-matter (i.e. Prompty format) will be the primary serialization format used. 2. Providing Agent state is not supported in the Agent Framework at present. 3. We need to decide if the Agent Framework should define an abstraction to allow any Agent to be invoked. 4. We will support JSON also as an out-of-the-box option. Currently Semantic Kernel supports three Agent types and these have the following properties: 1. [`ChatCompletionAgent`](https://learn.microsoft.com/en-us/dotnet/api/microsoft.semantickernel.agents.chatcompletionagent?view=semantic-kernel-dotnet): - `Arguments`: Optional arguments for the agent. (Inherited from ChatHistoryKernelAgent) - `Description`: The description of the agent (optional). (Inherited from Agent) - `HistoryReducer`: (Inherited from ChatHistoryKernelAgent) - `Id`: The identifier of the agent (optional). (Inherited from Agent) - `Instructions`: The instructions of the agent (optional). (Inherited from KernelAgent) - `Kernel`: The Kernel containing services, plugins, and filters for use throughout the agent lifetime. (Inherited from KernelAgent) - `Logger`: The ILogger associated with this Agent. (Inherited from Agent) - `LoggerFactory`: A ILoggerFactory for this Agent. (Inherited from Agent) - `Name`: The name of the agent (optional). (Inherited from Agent) 2. [`OpenAIAssistantAgent`](https://learn.microsoft.com/en-us/dotnet/api/microsoft.semantickernel.agents.agent.description?view=semantic-kernel-dotnet#microsoft-semantickernel-agents-agent-description): - `Arguments`: Optional arguments for the agent. - `Definition`: The assistant definition. - `Description`: The description of the agent (optional). (Inherited from Agent) - `Id`: The identifier of the agent (optional). (Inherited from Agent) - `Instructions`: The instructions of the agent (optional). (Inherited from KernelAgent) - `IsDeleted`: Set when the assistant has been deleted via DeleteAsync(CancellationToken). An assistant removed by other means will result in an exception when invoked. - `Kernel`: The Kernel containing services, plugins, and filters for use throughout the agent lifetime. (Inherited from KernelAgent) - `Logger`: The ILogger associated with this Agent. (Inherited from Agent) - `LoggerFactory`: A ILoggerFactory for this Agent. (Inherited from Agent) - `Name`: The name of the agent (optional). (Inherited from Agent) - `PollingOptions`: Defines polling behavior 3. [`AzureAIAgent`](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/src/Agents/AzureAI/AzureAIAgent.cs) - `Definition`: The assistant definition. - `PollingOptions`: Defines polling behavior for run processing. - `Description`: The description of the agent (optional). (Inherited from Agent) - `Id`: The identifier of the agent (optional). (Inherited from Agent) - `Instructions`: The instructions of the agent (optional). (Inherited from KernelAgent) - `IsDeleted`: Set when the assistant has been deleted via DeleteAsync(CancellationToken). An assistant removed by other means will result in an exception when invoked. - `Kernel`: The Kernel containing services, plugins, and filters for use throughout the agent lifetime. (Inherited from KernelAgent) - `Logger`: The ILogger associated with this Agent. (Inherited from Agent) - `LoggerFactory`: A ILoggerFactory for this Agent. (Inherited from Agent) - `Name`: The name of the agent (optional). (Inherited from Agent) When executing an Agent that was defined declaratively some of the properties will be determined by the runtime: - `Kernel`: The runtime will be responsible for create the `Kernel` instance to be used by the Agent. This `Kernel` instance must be configured with the models and tools that the Agent requires. - `Logger` or `LoggerFactory`: The runtime will be responsible for providing a correctly configured `Logger` or `LoggerFactory`. - **Functions**: The runtime must be able to resolve any functions required by the Agent. E.g. the VSCode extension will provide a very basic runtime to allow developers to test Agents and it should be able to resolve `KernelFunctions` defined in the current project. See later in the ADR for an example of this. For Agent properties that define behaviors e.g. `HistoryReducer` the Semantic Kernel **SHOULD**: - Provide implementations that can be configured declaratively i.e., for the most common scenarios we expect developers to encounter. - Allow implementations to be resolved from the `Kernel` e.g., as required services or possibly `KernelFunction`'s. ## Decision Drivers - Schema **MUST** be Agent Service agnostic i.e., will work with Agents targeting Azure, Open AI, Mistral AI, ... - Schema **MUST** allow model settings to be assigned to an Agent. - Schema **MUST** allow tools (e.g. functions, code interpreter, file search, ...) to be assigned to an Agent. - Schema **MUST** allow new types of tools to be defined for an Agent to use. - Schema **MUST** allow a Semantic Kernel prompt (including Prompty format) to be used to define the Agent instructions. - Schema **MUST** be extensible so that support for new Agent types with their own settings and tools, can be added to Semantic Kernel. - Schema **MUST** allow third parties to contribute new Agent types to Semantic Kernel. - … The document will describe the following use cases: 1. Metadata about the agent and the file. 2. Creating an Agent with access to function tools and a set of instructions to guide it's behavior. 3. Allow templating of Agent instructions (and other properties). 4. Configuring the model and providing multiple model configurations. 5. Configuring data sources (context/knowledge) for the Agent to use. 6. Configuring additional tools for the Agent to use e.g. code interpreter, OpenAPI endpoints, . 7. Enabling additional modalities for the Agent e.g. speech. 8. Error conditions e.g. models or function tools not being available. ### Out of Scope - This ADR does not cover the multi-agent declarative format or the process declarative format ## Considered Options - Use the [Declarative agent schema 1.2 for Microsoft 365 Copilot](https://learn.microsoft.com/en-us/microsoft-365-copilot/extensibility/declarative-agent-manifest-1.2) - Extend the Declarative agent schema 1.2 for Microsoft 365 Copilot - Extend the [Semantic Kernel prompt schema](https://learn.microsoft.com/en-us/semantic-kernel/concepts/prompts/yaml-schema#sample-yaml-prompt) ## Pros and Cons of the Options ### Use the Declarative agent schema 1.2 for Microsoft 365 Copilot Semantic Kernel already has support this, see the [declarative Agent concept sample](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/samples/Concepts/Agents/DeclarativeAgents.cs). - Good, this is an existing standard adopted by the Microsoft 365 Copilot. - Neutral, the schema splits tools into two properties i.e. `capabilities` which includes code interpreter and `actions` which specifies an API plugin manifest. - Bad, because it does support different types of Agents. - Bad, because it doesn't provide a way to specific and configure the AI Model to associate with the Agent. - Bad, because it doesn't provide a way to use a Prompt Template for the Agent instructions. - Bad, because `actions` property is focussed on calling REST API's and cater for native and semantic functions. ### Extend the Declarative agent schema 1.2 for Microsoft 365 Copilot Some of the possible extensions include: 1. Agent instructions can be created using a Prompt Template. 2. Agent Model settings can be specified including fallbacks based on the available models. 3. Better definition of functions e.g. support for native and semantic. - Good, because {argument a} - Good, because {argument b} - Neutral, because {argument c} - Bad, because {argument d} - … ### Extend the Semantic Kernel Prompt Schema - Good, because {argument a} - Good, because {argument b} - Neutral, because {argument c} - Bad, because {argument d} - … ## Decision Outcome Chosen option: "{title of option 1}", because {justification. e.g., only option, which meets k.o. criterion decision driver | which resolves force {force} | … | comes out best (see below)}. ### Consequences - Good, because {positive consequence, e.g., improvement of one or more desired qualities, …} - Bad, because {negative consequence, e.g., compromising one or more desired qualities, …} - … ## Validation {describe how the implementation of/compliance with the ADR is validated. E.g., by a review or an ArchUnit test} ## More Information ### Code First versus Declarative Format Below are examples showing the code first and equivalent declarative syntax for creating different types of Agents. Consider the following use cases: 1. `ChatCompletionAgent` 2. `ChatCompletionAgent` using Prompt Template 3. `ChatCompletionAgent` with Function Calling 4. `OpenAIAssistantAgent` with Function Calling 5. `OpenAIAssistantAgent` with Tools #### `ChatCompletionAgent` Code first approach: ```csharp ChatCompletionAgent agent = new() { Name = "Parrot", Instructions = "Repeat the user message in the voice of a pirate and then end with a parrot sound.", Kernel = kernel, }; ``` Declarative Semantic Kernel schema: ```yml type: chat_completion_agent name: Parrot instructions: Repeat the user message in the voice of a pirate and then end with a parrot sound. ``` **Note**: - `ChatCompletionAgent` could be the default agent type hence no explicit `type` property is required. #### `ChatCompletionAgent` using Prompt Template Code first approach: ```csharp string generateStoryYaml = EmbeddedResource.Read("GenerateStory.yaml"); PromptTemplateConfig templateConfig = KernelFunctionYaml.ToPromptTemplateConfig(generateStoryYaml); ChatCompletionAgent agent = new(templateConfig, new KernelPromptTemplateFactory()) { Kernel = this.CreateKernelWithChatCompletion(), Arguments = new KernelArguments() { { "topic", "Dog" }, { "length", "3" }, } }; ``` Agent YAML points to another file, the Declarative Agent implementation in Semantic Kernel already uses this technique to load a separate instructions file. Prompt template which is used to define the instructions. ```yml --- name: GenerateStory description: A function that generates a story about a topic. template: format: semantic-kernel parser: semantic-kernel inputs: - name: topic description: The topic of the story. is_required: true default: dog - name: length description: The number of sentences in the story. is_required: true default: 3 --- Tell a story about {{$topic}} that is {{$length}} sentences long. ``` **Note**: Semantic Kernel could load this file directly. #### `ChatCompletionAgent` with Function Calling Code first approach: ```csharp ChatCompletionAgent agent = new() { Instructions = "Answer questions about the menu.", Name = "RestaurantHost", Description = "This agent answers questions about the menu.", Kernel = kernel, Arguments = new KernelArguments(new OpenAIPromptExecutionSettings() { Temperature = 0.4, FunctionChoiceBehavior = FunctionChoiceBehavior.Auto() }), }; KernelPlugin plugin = KernelPluginFactory.CreateFromType(); agent.Kernel.Plugins.Add(plugin); ``` Declarative using Semantic Kernel schema: ```yml --- name: RestaurantHost name: RestaurantHost description: This agent answers questions about the menu. model: id: gpt-4o-mini options: temperature: 0.4 function_choice_behavior: type: auto functions: - MenuPlugin.GetSpecials - MenuPlugin.GetItemPrice --- Answer questions about the menu. ``` #### `OpenAIAssistantAgent` with Function Calling Code first approach: ```csharp OpenAIAssistantAgent agent = await OpenAIAssistantAgent.CreateAsync( clientProvider: this.GetClientProvider(), definition: new OpenAIAssistantDefinition("gpt_4o") { Instructions = "Answer questions about the menu.", Name = "RestaurantHost", Metadata = new Dictionary { { AssistantSampleMetadataKey, bool.TrueString } }, }, kernel: new Kernel()); KernelPlugin plugin = KernelPluginFactory.CreateFromType(); agent.Kernel.Plugins.Add(plugin); ``` Declarative using Semantic Kernel schema: Using the syntax below the assistant does not have the functions included in it's definition. The functions must be added to the `Kernel` instance associated with the Agent and will be passed when the Agent is invoked. ```yml --- name: RestaurantHost type: openai_assistant description: This agent answers questions about the menu. model: id: gpt-4o-mini options: temperature: 0.4 function_choice_behavior: type: auto functions: - MenuPlugin.GetSpecials - MenuPlugin.GetItemPrice metadata: sksample: true --- Answer questions about the menu. `` or ```yml --- name: RestaurantHost type: openai_assistant description: This agent answers questions about the menu. execution_settings: default: temperature: 0.4 tools: - type: function name: MenuPlugin-GetSpecials description: Provides a list of specials from the menu. - type: function name: MenuPlugin-GetItemPrice description: Provides the price of the requested menu item. parameters: '{"type":"object","properties":{"menuItem":{"type":"string","description":"The name of the menu item."}},"required":["menuItem"]}' --- Answer questions about the menu. ``` **Note**: The `Kernel` instance used to create the Agent must have an instance of `OpenAIClientProvider` registered as a service. #### `OpenAIAssistantAgent` with Tools Code first approach: ```csharp OpenAIAssistantAgent agent = await OpenAIAssistantAgent.CreateAsync( clientProvider: this.GetClientProvider(), definition: new(this.Model) { Instructions = "You are an Agent that can write and execute code to answer questions.", Name = "Coder", EnableCodeInterpreter = true, EnableFileSearch = true, Metadata = new Dictionary { { AssistantSampleMetadataKey, bool.TrueString } }, }, kernel: new Kernel()); ``` Declarative using Semantic Kernel: ```yml --- name: Coder type: openai_assistant tools: - type: code_interpreter - type: file_search --- You are an Agent that can write and execute code to answer questions. ``` ### Declarative Format Use Cases #### Metadata about the agent and the file ```yaml name: RestaurantHost type: azureai_agent description: This agent answers questions about the menu. version: 0.0.1 ``` #### Creating an Agent with access to function tools and a set of instructions to guide it's behavior #### Allow templating of Agent instructions (and other properties) #### Configuring the model and providing multiple model configurations #### Configuring data sources (context/knowledge) for the Agent to use #### Configuring additional tools for the Agent to use e.g. code interpreter, OpenAPI endpoints #### Enabling additional modalities for the Agent e.g. speech #### Error conditions e.g. models or function tools not being available ================================================ FILE: docs/decisions/0071-multi-agent-orchestration.md ================================================ --- # These are optional elements.

With the recent GA of the Semantic Kernel Agent Framework, which offers a [stable agent abstraction/APIs](https://github.com/microsoft/semantic-kernel/blob/main/python/semantic_kernel/agents/agent.py) and support for multiple agent services such as OpenAI Assistant and Chat Completion services, we are now able to build on top of it to create multi-agent systems. This will allow our customers to unlock even more complex scenarios. In addition, the recent collaboration with the AutoGen team that resulted in the shared agent runtime abstraction allowed us to leverage their work as the foundation on which we can build our framework. ## Problem Statement The current state of the Semantic Kernel Agent Framework is limited to single agents, i.e. agents cannot work collaboratively to solve user requests. We need to extend it to support multi-agent orchestration, which will allow our customers to unlock more possibilities using Semantic Kernel agents. Please refer to the [Considerations](#considerations) section to see success criteria for this proposal. ## Background Knowledge ### Terminology Before we dive into the details, let's clarify some terminologies that will be used throughout this document. | **Term** | **Definition** | | -------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------ | | **Actor** | An entity in the runtime that can send and receive messages. | | **[Runtime](https://microsoft.github.io/autogen/stable/user-guide/core-user-guide/core-concepts/architecture.html)** | Facilitates the communication between actors and manages the states and lifecycle of them. | | **Runtime Abstraction** | An abstraction that provides a common interface for different runtime implementations. | | **Agent** | A Semantic Kernel agent. | | **Orchestration** | Contains actors and rules on how they will interact with each others. | > We are using the term "actor" to avoid confusion with the term "agent" used in the Semantic Kernel Agent Framework. You may see the name "actor" used interchangeably with "agent" in the runtime documentation. To learn more about "actor"s in software design, please refer to: . > You may hear the term "pattern" in other contexts. "Pattern" is almost semantically identical to "orchestration" where the latter implies the management and execution of patterns. You can also think of "patterns" as types of "orchestrations". For example, "concurrent orchestration" is a type of orchestration that follows the concurrent pattern. ### The shared runtime abstraction from AutoGen > The runtime abstraction serves as the foundational layer for the system. A basic understanding of the runtime is recommended. For more details, refer to the [AutoGen Core User Guide](https://microsoft.github.io/autogen/stable/user-guide/core-user-guide/index.html). The AutoGen team has built a runtime abstraction (along with an in-process runtime implementation) that supports pub-sub communication between actors in a system. We have had the opportunity to leverage this work, which led to a shared agent runtime abstraction which Semantic Kernel will depend on. Depending on the actual runtime implementation, actors can be local or distributed. Our agent framework is **not** tied to a specific runtime implementation, a.k.a **runtime agnostic**. ## Considerations ### Orchestrations The first version of the multi-agent orchestration framework will provide a set of pre-built orchestrations that cover the most common patterns listed below. As time goes on, we will add more orchestrations based on customer feedback and will allow customers to easily create their own orchestrations using the building blocks provided by the framework. | **Orchestrations** | **Description** | | ------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Concurrent** | Useful for tasks that will benefit from independent analysis from multiple agents. | | **Sequential** | Useful for tasks that require a well-defined step-by-step approach. | | **Handoff** | Useful for tasks that are dynamic in nature and don't have a well-defined step-by-step approach. | | **GroupChat** | Useful for tasks that will benefit from inputs from multiple agents and a highly configurable conversation flow. | | **Magentic One** | GroupChat like with a planner based manager. Inspired by [Magentic One](https://www.microsoft.com/en-us/research/articles/magentic-one-a-generalist-multi-agent-system-for-solving-complex-tasks/). | > Please see [Appendix A](#appendix-a-pre-built-orchestrations) for a more detailed descriptions of the pre-built orchestrations. Using an orchestration should be as simple as the following: ```python agent_1 = ChatCompletionAgent(...) agent_2 = ChatCompletionAgent(...) group_chat = GroupChatOrchestration(members=[agent_1, agent_2], manager=RoundRobinGroupChatManager()) # The runtime can be a context manager for better resource management and developer experience. # We may also consider using a factory to create a default runtime instance. runtime = InProcessRuntime() runtime.start() orchestration_result = await group_chat.invoke(task="Hello world", runtime=runtime) result = await orchestration_result.get(timeout=20) print(result) await runtime.stop_when_idle() ``` ### Application responsibilities - The lifecycle of a runtime instance should be managed by the application and should be external to any orchestrations. - Orchestrations require a runtime instance only when they are invoked, not when they are created. ### Graph-like structure with lazy evaluation We should consider an orchestration as a template that describes how the agents will interact with each other similar to a directed graph. The actual execution of the orchestration should be done by the runtime. Therefore, the followings must be true: - Actors are registered to the runtime before execution starts, not when the orchestration is created. - The runtime is responsible for creating the actors and managing their lifecycle. ### Independent & isolated invocations An orchestration can be invoked multiple times and each invocation should be independent and isolated from each other. Invocations can also share the same runtime instance. This will require us to define clear invocation boundaries to avoid collisions, such as actor names or IDs. For example, in the following code snippet, the `task_1` and `task_2` are independent and don't share any context: ```python agent_1 = ChatCompletionAgent(...) agent_2 = ChatCompletionAgent(...) group_chat = GroupChatOrchestration(members=[agent_1, agent_2], manager=RoundRobinGroupChatManager()) runtime = InProcessRuntime() runtime.start() task_1 = await group_chat.invoke(task=TASK_1, runtime=runtime) task_2 = await group_chat.invoke(task=TASK_2, runtime=runtime) result_1 = await task_1.get(timeout=20) result_2 = await task_2.get(timeout=20) await runtime.stop_when_idle() ``` ### Support structured input and output types We need the orchestrations to accept structured inputs and return structured outputs, so that they will be easier to work with from a code perspective. This will also make it easier for developers to work with orchestrations that are not chat-based (although internally the agents will still be chat-based). ## Out of Scope - The runtime implementation is out of scope for this proposal. - Topics mentioned in the [Open Discussions](#open-discussions) section will not be addressed in the initial implementation of the multi-agent orchestration framework. However, we will keep them in mind for future iterations and we should leave enough room for future extensions. ## Proposals > Code snippets shown are not complete but they provide enough context to understand the proposal. ### Building blocks | **Component** | **Details** | | ------------------------ | -------------------------------------------------------------------------------------------------------------------- | | **Agent actor** | - Semantic Kernel agent
- Agent context: thread and history | | **Data transform logic** | - Provide hooks to transform the input/output of the orchestration from/to custom types. | | **Orchestration** | - Consists of multiple agent actors and other optional orchestration-specific actors. | | **Optional actors** | - Other actors that are not agent actors.
- For example, a group manager actor in the group chat orchestration. | ```mermaid graph TD %% Outer Block subgraph Orchestration subgraph Members[Members] subgraph AA0[Agent Actor] AG0[agent 0] end subgraph AA1[Agent Actor] AG1[agent 1] end end IT[Internal Topic] OA[Optional Actor] end %% Connections AA0 <-.Direct messaging.-> AA1 AA0 <-.Direct messaging.-> OA AA1 <-.Direct messaging.-> OA IT <-.Broadcast.-> AA0 IT <-.Broadcast.-> AA1 IT <-.Broadcast.-> OA ``` #### Agent Actor This is a wrapper around a Semantic Kernel agent so that the agent can send and receive messages from the runtime. The `AgentActorBase` will inherit the [`RoutedAgent`](https://microsoft.github.io/autogen/stable/reference/python/autogen_core.html#autogen_core.RoutedAgent) class: ```python class AgentActorBase(RoutedAgent): """A agent actor for multi-agent orchestration running on Agent runtime.""" def __init__(self, agent: Agent) -> None: """Initialize the agent container. Args: agent (Agent): An agent to be run in the container. """ self._agent = agent self._agent_thread = None # Chat history to temporarily store messages before the agent thread is created self._chat_history = ChatHistory() RoutedAgent.__init__(self, description=agent.description or "Semantic Kernel Agent") ``` Orchestrations will have their own agent actor that extends the `AgentActorBase` because each orchestration can have its own set of message handlers. > To learn more about messages and message handlers, please refer to the [AutoGen documentation](https://microsoft.github.io/autogen/stable/user-guide/core-user-guide/framework/message-and-communication.html). For example, for the group chat orchestration, the agent actor will look like this: ```python class GroupChatAgentActor(AgentActorBase): """An agent actor for agents that process messages in a group chat.""" @message_handler async def _handle_start_message(self, message: GroupChatStartMessage, ctx: MessageContext) -> None: """Handle the initial message(s) provided by the user.""" ... @message_handler async def _handle_response_message(self, message: GroupChatResponseMessage, ctx: MessageContext) -> None: """Handle the response message from other agents in the group chat.""" ... @message_handler async def _handle_request_message(self, message: GroupChatRequestMessage, ctx: MessageContext) -> None: """Handle the request message from the group manager.""" ... ``` Agent actors in other orchestrations will handle different message types or different number of message types. This proposal doesn't make any restrictions on how agent actors interact with each other inside an orchestration, i.e. rules are defined by individual orchestrations. #### Data Transform Logic The signature of the data transform logic will be as follows: ```python DefaultTypeAlias = ChatMessageContent | list[ChatMessageContent] TIn = TypeVar("TIn", default=DefaultTypeAlias) TOut = TypeVar("TOut", default=DefaultTypeAlias) input_transform: Callable[[TIn], Awaitable[DefaultTypeAlias] | DefaultTypeAlias] output_transform: Callable[[DefaultTypeAlias], Awaitable[TOut] | TOut] ``` `TIn` denotes the type of input the orchestration will take, while `TOut` denotes the type of output the orchestration will return to the caller. We will use `ChatMessageContent` and `list[ChatMessageContent]` as the default types. This means that the orchestration will accept a single chat message or a list of chat messages as input and return a single chat message or a list of chat messages as output. > We can offer a set of default transforms to improve the developer quality of life. We can also have LLMs that automatically perform the transforms given the types. #### Orchestration An orchestration is simply a collection of Semantic Kernel agents and the rules that govern how they will interact with each other. Concrete implementations have to provide logic for how to start and prepare an invocation of the orchestration. "Preparing" an invocation simply means registering the actors with the runtime and setting up the communication channels between them based on the orchestration type. ```python class OrchestrationBase(ABC, Generic[TIn, TOut]): def __init__( self, members: list[Agent], input_transform: Callable[[TIn], Awaitable[DefaultTypeAlias] | DefaultTypeAlias] | None = None, output_transform: Callable[[DefaultTypeAlias], Awaitable[TOut] | TOut] | None = None, ) -> None: """Initialize the orchestration base. Args: members (list[Agent]): The list of agents or orchestrations to be used. input_transform (Callable | None): A function that transforms the external input message. output_transform (Callable | None): A function that transforms the internal output message. """ ... async def invoke( self, task: str | DefaultTypeAlias | TIn, runtime: AgentRuntime, ) -> OrchestrationResult: """Invoke the orchestration and return an result immediately which can be awaited later. The runtime is supplied by the application at invocation time, not at creation time. Orchestrations are runtime-agnostic and can be used with any runtime that implements the runtime abstraction. """ orchestration_result = OrchestrationResult[TOut]() async def result_callback(result: DefaultTypeAlias) -> None: """Callback function that is called when the result is ready.""" ... ... # This unique topic type is used to isolate the invocation from others. internal_topic_type = uuid.uuid4().hex await self._prepare(runtime, internal_topic_type, result_callback) ... await self._start(runtime, internal_topic_type, orchestration_result.cancellation_token) return orchestration_result @abstractmethod async def _start( self, runtime: AgentRuntime, internal_topic_type: str, cancellation_token: CancellationToken, ) -> None: ... @abstractmethod async def _prepare( self, runtime: AgentRuntime, internal_topic_type: str, result_callback: Callable[[DefaultTypeAlias], Awaitable[None]] | None = None, ) -> str: ... ``` When using the orchestration, the user will can optionally set `TIn` and `TOut` and provide the input and output transforms. For example, in Python, the user can do the following: ```python class MyTypeA: pass class MyTypeB: pass sequential_orchestration = SequentialOrchestration[MyTypeA, MyTypeB]( members=[agent_0, agent_1], input_transform=input_transform_func, output_transform=output_transform_func, ) ``` And depending on the language, we can offer defaults so that only advanced users will need to set `TIn` and `TOut`. For example, in Python, we can do the following: ```python DefaultTypeAlias = ChatMessageContent | list[ChatMessageContent] TIn = TypeVar("TIn", default=DefaultTypeAlias) TOut = TypeVar("TOut", default=DefaultTypeAlias) ``` And in .Net, we can do the following: ```csharp public class SequentialOrchestration : AgentOrchestration { ... } public sealed class SequentialOrchestration : SequentialOrchestration { ... } ``` The orchestration result will be represented as such: ```python class OrchestrationResult(KernelBaseModel, Generic[TOut]): value: TOut | None = None event: asyncio.Event = Field(default_factory=lambda: asyncio.Event()) cancellation_token: CancellationToken = Field(default_factory=lambda: CancellationToken()) async def get(self, timeout: float | None = None) -> TOut: """Get the result of the invocation. Args: timeout (float | None): The timeout in seconds. If None, wait indefinitely. Raises: TimeoutError: If the timeout is reached before the result is ready. RuntimeError: If the invocation is cancelled. Returns: TOut: The result of the invocation. """ ... def cancel(self) -> None: """Cancel the invocation. This method will cancel the invocation and set the cancellation token. Actors that have received messages will continue to process them, but no new messages will be processed. """ ... ``` ## Open Discussions The following items are important topics we need to consider and need further discussion. However, they shouldn't block the initial implementation of the multi-agent orchestration framework. ### State management Definitions for `resume` and `restart` before proceeding: - **Resume**: The process is still active but at an idle state waiting for some events to continue. The runtime resumes the process from the idle state. - **Restart**: The process is no longer running. It has been stopped manually or errors had occurred. The orchestration can be restarted from scratch, or from a previous checkpoint. Restarting is idempotent, meaning that the orchestration can be restarted multiple times from the same checkpoint without side effects on the orchestration, runtime, and agents. Orchestrations can be long-running, hours, days, and even years. And they can be short-lived, minutes or seconds or less. The states of an orchestration can mean the following: - An actively running orchestration that is in an idle state waiting for user input or other events to continue. - An orchestration that has entered an error state. - etc. **Resuming** from an idle state will be handled by the runtime. The runtime is responsible for saving the state of the actors and rehydrating them when the orchestration is resumed. Another type of states are the agents' conversational context. There is active work on agent **threads** and **memories**, and we should consider how these concepts fit into the framework. Ideally, we want the ability to **restart** an orchestration on some existing agent context. Please refer to [Agent context](#agent-context) for further discussion. ### Agent context We mentioned in the [State management](#state-management) section that orchestrations do not manage the state of the agents, while we do want to support the ability to invoke/restart an orchestration on some existing agent context. This means that we need to have a way to provide the state of the agents to the orchestrations. An option is to have a context provider that provides agent contexts given an agent ID. The context provider will be attached to the agent actors for the agent actor to retrieve and update contexts. Each new invocation of an orchestration will return a text representation (see [Support declarative orchestrations](#support-declarative-orchestrations)) of the orchestration, which can be used to rehydrate the orchestration. ### Error handling We need a clear story for customers on how to handle errors in the runtime. The runtime is managed by the application. Orchestrations will not be able to capture errors that happen in the runtime and actor level. The `in_process` runtime currently have a flag `ignore_unhandled_exceptions` which by default is set to `True` and can be set at construction time. Setting this flag to `False` will cause the runtime to stop and raise if an exception occurs during the execution. It will get more complicated when we have distributed runtimes. We should also consider retries and idempotency at the runtime level. ### Human in the loop Human-in-the-loop is a critical component in autonomous systems. We need to consider how to support human-in-the-loop in the multi-agent orchestration framework. - Support cancellation of an invocation - Notify the user of important events - Support distributed use cases. For example, the client may live on a different system than the orchestration. > The group chat orchestration has an experimental feature that allows input from users. Please refer to the [Group Chat Orchestration](#group-chat-orchestration) section for more details. ### Composition Composition allows users to take existing orchestrations and use them to build more powerful orchestrations. Think of replacing an agent in an orchestration with another orchestration. This will unlock more complex scenarios with less effort. However, this comes with challenges, including: - The handling of mismatched input and output types of orchestrations. - The communication between actors and orchestrations. - The handling of the lifecycle of the orchestrations that is inside another orchestration. - The propagation of events from an orchestration that is nested inside another orchestration. - Simplicity of use: user don't have to understand the inner workings of the orchestrations to use them. - Simplicity of implementation: developers can create new orchestrations with the same building blocks as the existing orchestrations. ### Distributed orchestrations Although orchestrations are not tied to a specific runtime, we need to understand how actors and orchestrations will be distributed if a runtime allows distribution. The following questions need to be answered: - Actor registrations happen locally on the same machine with the runtime via a factory. Does the factory need to be distributed? - How will the runtime handle distributed actor failures? - How will the runtime handle the cancellation of an invocation of an orchestration that is distributed? - How will the result of an invocation be returned via a callback function or some other mechanism if the orchestration is distributed? ### Support declarative orchestrations Declarative orchestrations provide a low-code solution for users. We are already working on declarative agents, and we can leverage that work to create declarative orchestrations. ### Guardrails Safety is also a priority. A powerful orchestration may accomplish a lot of things, but it may also do a lot of harm. We need to consider how to implement guardrails in the multi-agent orchestration framework, similar to what OpenAI has in their [agent SDK](https://openai.github.io/openai-agents-python/guardrails/). - Should we have guardrails in the orchestration level? - Should we have guardrails in the actor level? - Should we have guardrails in the agent level? ### Observability SK being an enterprise solution, we should also consider observability. ### A middle layer before the runtime for additional security and safety We can consider adding a layer before the runtime that standardize all messages between actors for the following benefits: - Built-in idempotency & retries: the standardized message type carries id, causation_id, retry_count, ttl, which can enable deterministic deduplication, causal graphs for telemetry, and safe redelivery. - First-class observability: standardized message fields can map 1:1 to OpenTelemetry attributes for traceability and metrics on every hop. - Persistence/rehydration: standardized messages can be serialized to storage and deserialized as needed. - Guardrails: the uniform wrapper allows policy/guardrail checks to be centralized in the runtime, so no payload reaches an agent unchecked. ## Appendix A: Pre-built orchestrations ### Concurrent Orchestration The concurrent orchestration works in the following steps: 1. The orchestration is invoked with a task. 2. The orchestration broadcasts the task to all actors. 3. Actors start processing the task and send the result to the result collector. 4. The result collector collects the results and when the expected number of results are received, it calls a callback function to signal the end of the orchestration. ```mermaid graph TD %% Outer Block subgraph Concurrent Orchestration subgraph Members[Members] AG0[agent 0] AG1[agent 1] end IT[Internal Topic] RC[Result Collector] end IT --> |ConcurrentRequestMessage| AG0 IT --> |ConcurrentRequestMessage| AG1 AG0 --> |ConcurrentResponseMessage| RC AG1 --> |ConcurrentResponseMessage| RC ``` ### Sequential Orchestration The sequential orchestration works in the following steps: 1. The orchestration is invoked with a task. 2. The orchestration sends the task to the first actor. 3. The first actor processes the task and sends the result to the next actor. 4. The last actor processes the result and sends the result to the result collector. 5. The result collector calls a callback function to signal the end of the orchestration. ```mermaid graph TD %% Outer Block subgraph Sequential Orchestration subgraph Members[Members] AG0[agent 0] AG1[agent 1] end RC[Result Collector] end %% Connections AG0 --> |SequentialRequestMessage| AG1 AG1 --> |SequentialResponseMessage| RC ``` ### Handoff Orchestration The handoff orchestration works in the following steps: 1. The orchestration is invoked with a task. 2. The orchestration sends the task to all actors. 3. The orchestration sends a "request to speak" message to the first actor. 4. The first actor processes the task, broadcast the conversation context, and decides if it needs to delegate the task to another actor. 5. If the first actor decides to delegate the task, it sends a "request to speak" message to the other actor. 6. The other actor processes the task and decides if it needs to delegate the task to another actor. 7. The process continues until the last actor decides that the task is complete and calls a callback function to signal the end of the orchestration. ```mermaid graph TD %% Outer Block subgraph Handoff Orchestration subgraph Members[Members] AG0[agent 0] AG1[agent 1] end IT[Internal Topic] end %% Connections IT <--> |Broadcast| AG0 IT <--> |Broadcast| AG1 ``` ### Group Chat Orchestration The group chat orchestration works in the following steps: 1. The orchestration is invoked with a task. 2. The orchestration sends the task to all actors. 3. The orchestration sends the task to the group manager, which will trigger the group chat manager to start the orchestration. 4. The group manager decides the state of the conversation from one of the following: - Request User Input -> calls a callback function and waits for user input. - Terminate - Next Actor 5. If the conversation needs to continue, the group manager picks the next actor and sends a "request to speak" message to the actor. 6. The actor processes the request and broadcasts the response to the internal topic. 7. All other actors receive the response and add the response to their conversation context. 8. The group manager receives the response and continues from step 4. 9. If the conversation is over, the group manager retrieves a result and calls a callback function to signal the end of the orchestration. ```mermaid graph TD %% Outer Block subgraph Group Chat Orchestration subgraph Members[Members] AG0[agent 0] AG1[agent 1] end IT[Internal Topic] GM[Group Manager] end %% Connections IT <--> |Broadcast| AG0 IT <--> |Broadcast| AG1 IT <--> |Broadcast| GM ``` The group chat manager is responsible for managing the conversation flow. It will have the following responsibilities: ```python class GroupChatManager(KernelBaseModel, ABC): """A group chat manager that manages the flow of a group chat.""" user_input_func: Callable[[ChatHistory], Awaitable[str]] | None = None @abstractmethod async def should_request_user_input(self, chat_history: ChatHistory) -> bool: raise NotImplementedError @abstractmethod async def should_terminate(self, chat_history: ChatHistory) -> bool: raise NotImplementedError @abstractmethod async def select_next_agent(self, chat_history: ChatHistory, participant_descriptions: dict[str, str]) -> str: raise NotImplementedError @abstractmethod async def filter_results(self, chat_history: ChatHistory) -> ChatMessageContent: raise NotImplementedError ``` ### Magentic One Orchestration Magentic one is a group chat-like orchestration with a special group manager. Refer to the [Magentic One blog](https://www.microsoft.com/en-us/research/articles/magentic-one-a-generalist-multi-agent-system-for-solving-complex-tasks/) or [paper](https://www.microsoft.com/en-us/research/wp-content/uploads/2024/11/MagenticOne.pdf) for more details. ================================================ FILE: docs/decisions/0072-agents-with-memory.md ================================================ --- # These are optional elements.

By memory we mean the capability to remember information and skills that are learned during a conversation and re-use those later in the same conversation or later in a subsequent conversation. ## Context and Problem Statement Today we support multiple agent types with different characteristics: 1. In process vs remote. 2. Remote agents that store and maintain conversation state in the service vs those that require the caller to provide conversation state on each invocation. We need to support advanced memory capabilities across this range of agent types. ### Memory Scope Another aspect of memory that is important to consider is the scope of different memory types. Most agent implementations have instructions and skills but the agent is not tied to a single conversation. On each invocation of the agent, the agent is told which conversation to participate in, during that invocation. Memories about a user or about a conversation with a user is therefore extracted from one of these conversation and recalled during the same or another conversation with the same user. These memories will typically contain information that the user would not like to share with other users of the system. Other types of memories also exist which are not tied to a specific user or conversation. E.g. an Agent may learn how to do something and be able to do that in many conversations with different users. With these type of memories there is of cousrse risk in leaking personal information between different users which is important to guard against. ### Packaging memory capabilities All of the above memory types can be supported for any agent by attaching software components to conversation threads. This is achieved via a simple mechanism of: 1. Inspecting and using messages as they are passed to and from the agent. 2. Passing additional context to the agent per invocation. With our current `AgentThread` implementation, when an agent is invoked, all input and output messages are already passed to the `AgentThread` and can be made available to any components attached to the `AgentThread`. Where agents are remote/external and manage conversation state in the service, passing the messages to the `AgentThread` may not have any affect on the thread in the service. This is OK, since the service will have already updated the thread during the remote invocation. It does however, still allow us to subscribe to messages in any attached components. For the second requirement of getting additional context per invocation, the agent may ask the thread passed to it, to in turn ask each of the components attached to it, to provide context to pass to the Agent. This enables the component to provide memories that it contains to the Agent as needed. Different memory capabilities can be built using separate components. Each component would have the following characteristics: 1. May store some context that can be provided to the agent per invocation. 2. May inspect messages from the conversation to learn from the conversation and build its context. 3. May register plugins to allow the agent to directly store, retrieve, update or clear memories. ### Suspend / Resume Building a service to host an agent comes with challenges. It's hard to build a stateful service, but service consumers expect an experience that looks stateful from the outside. E.g. on each invocation, the user expects that the service can continue a conversation they are having. This means that where the the service is exposing a local agent with local conversation state management (e.g. via `ChatHistory`) that conversation state needs to be loaded and persisted for each invocation of the service. It also means that any memory components that may have some in-memory state will need to be loaded and persisted too. For cases like this, the `OnSuspend` and `OnResume` methods allow notification of the components that they need to save or reload their state. It is up to each of these components to decide how and where to save state to or load state from. ## Proposed interface for Memory Components The types of events that Memory Components require are not unique to memory, and can be used to package up other capabilities too. The suggestion is therefore to create a more generally named type that can be used for other scenarios as well and can even be used for non-agent scenarios too. This type should live in the `Microsoft.SemanticKernel.Abstractions` nuget, since these components can be used by systems other than just agents. ```csharp namespace Microsoft.SemanticKernel; public abstract class AIContextBehavior { public virtual IReadOnlyCollection AIFunctions => Array.Empty(); public virtual Task OnThreadCreatedAsync(string? threadId, CancellationToken cancellationToken = default); public virtual Task OnThreadDeleteAsync(string? threadId, CancellationToken cancellationToken = default); // OnThreadCheckpointAsync not included in initial release, maybe in future. public virtual Task OnThreadCheckpointAsync(string? threadId, CancellationToken cancellationToken = default); public virtual Task OnNewMessageAsync(string? threadId, ChatMessage newMessage, CancellationToken cancellationToken = default); public abstract Task OnModelInvokeAsync(ICollection newMessages, CancellationToken cancellationToken = default); public virtual Task OnSuspendAsync(string? threadId, CancellationToken cancellationToken = default); public virtual Task OnResumeAsync(string? threadId, CancellationToken cancellationToken = default); } ``` ## Managing multiple components To manage multiple components I propose that we have a `AIContextBehavior`. This class allows registering components and delegating new message notifications, ai invocation calls, etc. to the contained components. ## Integrating with agents I propose to add a `AIContextBehaviorManager` to the `AgentThread` class, allowing us to attach components to any `AgentThread`. When an `Agent` is invoked, we will call `OnModelInvokeAsync` on each component via the `AIContextBehaviorManager` to get a combined set of context to pass to the agent for this invocation. This will be internal to the `Agent` class and transparent to the user. ```csharp var additionalInstructions = await currentAgentThread.OnModelInvokeAsync(messages, cancellationToken).ConfigureAwait(false); ``` ## Usage examples ### Multiple threads using the same memory component ```csharp // Create a vector store for storing memories. var vectorStore = new InMemoryVectorStore(); // Create a memory store that is tired to a "Memories" collection in the vector store and stores memories under the "user/12345" namespace. using var textMemoryStore = new VectorDataTextMemoryStore(vectorStore, textEmbeddingService, "Memories", "user/12345", 1536); // Create a memory component to will pull user facts from the conversation, store them in the vector store // and pass them to the agent as additional instructions. var userFacts = new UserFactsMemoryComponent(this.Fixture.Agent.Kernel, textMemoryStore); // Create a thread and attach a Memory Component. var agentThread1 = new ChatHistoryAgentThread(); agentThread1.ThreadExtensionsManager.Add(userFacts); var asyncResults1 = agent.InvokeAsync("Hello, my name is Caoimhe.", agentThread1); // Create a second thread and attach a Memory Component. var agentThread2 = new ChatHistoryAgentThread(); agentThread2.ThreadExtensionsManager.Add(userFacts); var asyncResults2 = agent.InvokeAsync("What is my name?.", agentThread2); // Expected response contains Caoimhe. ``` ### Using a RAG component ```csharp // Create Vector Store and Rag Store/Component var vectorStore = new InMemoryVectorStore(); using var ragStore = new TextRagStore(vectorStore, textEmbeddingService, "Memories", 1536, "group/g2"); var ragComponent = new TextRagComponent(ragStore, new TextRagComponentOptions()); // Upsert docs into vector store. await ragStore.UpsertDocumentsAsync( [ new TextRagDocument("The financial results of Contoso Corp for 2023 is as follows:\nIncome EUR 174 000 000\nExpenses EUR 152 000 000") { SourceName = "Contoso 2023 Financial Report", SourceReference = "https://www.consoso.com/reports/2023.pdf", Namespaces = ["group/g2"] } ]); // Create a new agent thread and register the Rag component var agentThread = new ChatHistoryAgentThread(); agentThread.ThreadExtensionsManager.RegisterThreadExtension(ragComponent); // Inovke the agent. var asyncResults1 = agent.InvokeAsync("What was the income of Contoso for 2023", agentThread); // Expected response contains the 174M income from the document. ``` ## Decisions to make ### Extension base class name 1.

Feel free to remove any of them. status: accepted contact: sergeymenshykh date: 2025-05-13 deciders: markwallace, rbarreto, dmytrostruk, westey-m consulted: informed: --- ## Context and Problem Statement Currently, Semantic Kernel (SK) advertises **all** functions to the AI model, regardless of their source, whether they are from all registered plugins or provided directly when configuring function choice behavior. This approach works perfectly for most scenarios where there are not too many functions, and the AI model can easily choose the right one. However, when there are many functions available, AI models may struggle to select the appropriate function, leading to confusion and suboptimal performance. This can result in the AI model calling functions that are not relevant to the current context or conversation, potentially causing the entire scenario to fail. This ADR consider different options to provide context-based function selection and advertisement mechanism to such components as SK agents, chat completion services, and M.E.AI chat clients. ## Decision Drivers - It should be possible to advertise functions dynamically based on the context of the conversation. - It should seamlessly integrate with SK and M.E.AI AI connectors and SK agents. - It should have access to context and functions without the need for complex plumbing. ## Out of Scope - A particular implementation of the function selection algorithm whether it's RAG or any other. ## Option 1: External Vectorization and Search This option is demonstrated in the following sample: [PluginSelectionWithFilters.UsingVectorSearchWithChatCompletionAsync](https://github.com/microsoft/semantic-kernel/blob/6eff772c6034992a9db6e10ac12dd445a19d81a8/dotnet/samples/Concepts/Optimization/PluginSelectionWithFilters.cs#L104C23-L104C63) which uses the `PluginStore` class to vectorize kernel function and `FunctionProvider` to find functions relevant to the prompt: ````csharp // Register services IKernelBuilder builder = Kernel.CreateBuilder(); builder.Services.AddInMemoryVectorStore(); builder.Services.AddSingleton(); builder.Services.AddSingleton(); // Register plugins Kernel kernel = builder.Build(); kernel.ImportPluginFromType(); kernel.ImportPluginFromType(); // Vectorize all functions in the kernel IPluginStore pluginStore = kernel.GetRequiredService(); await pluginStore.SaveAsync(collectionName: "functions", kernel.Plugins); const string Prompt = "Provide latest headlines"; // Do RAG to find the relevant function for the prompt IFunctionProvider functionProvider = kernel.GetRequiredService(); KernelFunction[] relevantFunctions = await functionProvider.GetRelevantFunctionsAsync(collectionName: "functions", Prompt, kernel.Plugins, numberOfFunctions: 1); // Set the relevant functions to be advertised to the AI model executionSettings.FunctionChoiceBehavior = FunctionChoiceBehavior.Auto(relevantFunctions); // Do the chat completion var chatHistory = new ChatHistory(); chatHistory.AddUserMessage(Prompt); var chatCompletionService = kernel.GetRequiredService(); var result = await chatCompletionService.GetChatMessageContentAsync(chatHistory, executionSettings, kernel); Console.WriteLine(result); ```` It's invoked per operation rather than per AI model request; one operation call may result in multiple AI model requests in cases where the AI model performs function calling. Pros: - Can be used with all AI components, including SK chat completion services, SK agents, and M.E.AI chat clients. Cons: - Complex integration of all the parts (vectorization of functions, function search, advertisement of functions) of the solution together. - Doesn't support function choice behavior configured in prompt templates. ## Option 1A: Function Invocation Filter This option is demonstrated in the following sample: [PluginSelectionWithFilters.UsingVectorSearchWithKernelAsync](https://github.com/microsoft/semantic-kernel/blob/6eff772c6034992a9db6e10ac12dd445a19d81a8/dotnet/samples/Concepts/Optimization/PluginSelectionWithFilters.cs#L30C23-L30C55). It's identical to Option 1 for vectorization part and slightly deviates for the function selection part, which is implemented as a function invocation filter that intercepts calls to the `InvokePromptAsync` function, identifies the relevant functions to the prompt, and sets them to be advertised to the AI model via execution settings: ````csharp // Register services IKernelBuilder builder = Kernel.CreateBuilder(); builder.Services.AddInMemoryVectorStore(); builder.Services.AddSingleton(); builder.Services.AddSingleton(); // Register plugins Kernel kernel = builder.Build(); kernel.ImportPluginFromType(); kernel.ImportPluginFromType(); // Vectorize all functions in the kernel IPluginStore pluginStore = kernel.GetRequiredService(); await pluginStore.SaveAsync(collectionName: "functions", kernel.Plugins); // Register function invocation filter IFunctionProvider functionProvider = kernel.GetRequiredService(); kernel.FunctionInvocationFilters.Add(new PluginSelectionFilter(functionProvider: functionProvider, collectionName: "functions")); // Do the chat completion KernelArguments kernelArguments = new(executionSettings) { ["Request"] = "Provide latest headlines" }; await kernel.InvokePromptAsync("{{$Request}}", kernelArguments); // Function invocation filter class PluginSelectionFilter(IFunctionProvider functionProvider, string collectionName) { public async Task OnFunctionInvocationAsync(FunctionInvocationContext context, Func next) { string request = context.Arguments["Request"]; if (context.Function.Name.Contains(nameof(KernelExtensions.InvokePromptAsync)) && !string.IsNullOrWhiteSpace(request)) { var functions = await functionProvider.GetRelevantFunctionsAsync(collectionName, request, plugins, numberOfFunctions); context.Arguments.ExecutionSettings.FunctionChoiceBehavior = FunctionChoiceBehavior.Auto(functions); } await next(context); } } ```` It's invoked per operation rather than per AI model request; one operation call may result in multiple AI model requests in cases where the AI model performs function calling. Pros: Cons: - Relies on usage of the `InvokePromptAsync` function, making it unusable for all scenarios except those where the `kernel.InvokePromptAsync` function is used. - Doesn't support function choice behavior configured in prompt templates. ## Option 2: M.E.AI ChatClient Decorator This option presumes having an implementation of the `M.E.AI.IChatClient` interface, such as the `ContextFunctionSelectorChatClient` class, which will vectorize all functions available in the `ChatOptions` parameter of either `GetResponseAsync` or `GetResponseStreamAsync` methods. It will then search for functions relevant to the context represented by the list of chat messages passed to one of these methods: ````csharp public class ContextFunctionSelectorChatClient : DelegatingChatClient { protected ContextFunctionSelectorChatClient(IChatClient innerClient) : base(innerClient) { } public override async Task GetResponseAsync(IEnumerable messages, ChatOptions? options = null) { ChatOptions? targetOptions = options; if (options?.Tools?.Any() ?? false) { targetOptions = options.Clone(); AITool[] functionsToAdvertise = await this.GetRelevantFunctions(options, messages).ConfigureAwait(false); targetOptions.Tools = functionsToAdvertise; } return await base.GetResponseAsync(messages, targetOptions, ct).ConfigureAwait(false); } private async Task GetRelevantFunctions(ChatOptions options, IEnumerable messages) { // 1. Vectorize all the functions form the `options.Tool` collection, if not already vectorized. // 2. Vectorize the context represented by the `messages` collection. // 3. Search for and return the most relevant functions using the vectorized context. } public override IAsyncEnumerable GetStreamingResponseAsync(IEnumerable messages, ChatOptions? options = null) { // similar to GetResponseAsync, but for streaming } } // Usage with M.E.AI chat client ChatClient chatClient = new("model", "api-key"); IChatClient client = chatClient.AsIChatClient() .AsBuilder() .UseFunctionInvocation() .UseContextFunctionSelector() .Build(); // Usage with SK chat completion service IChatCompletionService chatCompletionService = new OpenAIChatCompletionService("", ""); IChatClient client = chatCompletionService.AsChatClient() .AsBuilder() .UseContextFunctionSelector() .Build(); ```` The decorator is invoked per operation rather than per AI model request; one operation call may result in multiple AI model requests in cases where the AI model performs function calling. Pros: - Works seamlessly with SK chat completion services and M.E.AI chat clients. - Easy wiring aligned with the initialization pattern adopted by M.E.AI. - No need for a new abstraction. - Easy to add new function selectors and chain them together. Cons: - Works with chat completion agents only and does not work with SK agents that don't use the chat completion service. - Doesn't support function choice behavior configured in prompt templates. ## Option 3: Function Advertisement Filter This option assumes having a new filter type that will be used to select the functions to be advertised to the AI model based on the context of the conversation: ````csharp // Register plugins Kernel kernel = new Kernel(); kernel.ImportPluginFromType(); kernel.ImportPluginFromType(); // Register function advertisement filter kernel.FunctionAdvertisementFilters.Add(new ContextFunctionSelectorFilter()); // Do the chat completion await kernel.InvokePromptAsync("Provide latest headlines"); // Function invocation filter class ContextFunctionSelectorFilter() { public async Task OnFunctionsAdvertisementAsync(FunctionAdvertisementContext context, Func next); { // 1. Vectorize all the functions form the `context.Functions` collection, if not already vectorized. // 2. Vectorize the context represented by the `context.ChatHistory` collection. // 3. Search for and assign the most relevant functions using the vectorized context to `context.Functions` property. } } ```` The filter can be invoked per operation and per AI model request as well; one operation call may result in multiple AI model requests in cases where the AI model performs function calling. Pros: - Familiar concept for SK users. - Works with chat completion services. - Works with both chat completion and non-chat completion **SK** agents, provided they can provide context to the filter. Cons: - New abstraction is required. - Public API surface of Kernel needs to be extended. - All AI components: SK agents, chat completion services, and M.E.AI chat clients adapters need to be updated to invoke the filter. ## Option 4: FunctionChoiceBehavior Callback This options presume extending the existing `AutoFunctionChoiceBehavior`, `RequiredFunctionChoiceBehavior` and `NoneFunctionChoiceBehavior` classes with a new constructor that takes a function selector as a parameter and uses it to select the functions based on the context to be advertised to the AI model. ````csharp // Register services IKernelBuilder builder = Kernel.CreateBuilder(); builder.Services.AddInMemoryVectorStore(); builder.Services.AddSingleton(); builder.Services.AddSingleton(); // Register plugins Kernel kernel = builder.Build(); kernel.ImportPluginFromType(); kernel.ImportPluginFromType(); // Set the relevant functions to be advertised to the AI model executionSettings.FunctionChoiceBehavior = FunctionChoiceBehavior.Auto(FunctionSelector); // Do the chat completion var chatHistory = new ChatHistory(); chatHistory.AddUserMessage("Provide latest headlines"); var chatCompletionService = kernel.GetRequiredService(); var result = await chatCompletionService.GetChatMessageContentAsync(chatHistory, executionSettings, kernel); Console.WriteLine(result); async Task> FunctionSelector(FunctionChoiceBehaviorConfigurationContext context) { // Vectorize all the functions form the `context.Functions` collection IPluginStore pluginStore = context.Kernel.GetRequiredService(); await pluginStore.SaveAsync(collectionName: "functions", context.Kernel.Plugins); // Search for the most relevant functions using the vectorized context IFunctionProvider functionProvider = kernel.GetRequiredService(); IList relevantFunctions = await functionProvider.GetRelevantFunctionsAsync(collectionName: "functions", context.ChatHistory, kernel.Plugins, numberOfFunctions: 1); return relevantFunctions; } ```` The filter can be invoked per operation and per AI model request as well; one operation call may result in multiple AI model requests in cases where the AI model performs function calling. Pros: Cons: - Doesn't support function choice behavior configured in prompt templates. - Can only be used by components that use `FunctionChoiceBehavior`: SK chat completion services and chat completion agents. ## Options Applicability This table summarizes the applicability of the options described above to the different components of the Semantic Kernel and M.E.AI: | Option | Scope | OpenAI & AzureAI Agents | Bedrock Agent | Chat Completion Agent | SK Chat Completion Service | M.E.AI Chat Client | |----------------------------------------|-----------|-------------------------|-----------------------|-----------------------|----------------------------|----------------------| | **1.** External Vectorization & Search | Operation | Yes1,2 | Yes1,3 | Yes1,2or4 | Yes1,2or4 | Yes1 | | **1A.** Function Invocation Filter | Operation | No5 | No5 | No5 | No5 | No | | **2.** M.E.AI ChatClient Decorator | Operation | No | No | Yes6 | Yes6 | Yes | | **3.** Function Advertisement Filter | Op & Req | Yes | No3 | Yes | Yes | Yes7 | | **4.** FunctionChoiceBehavior Callback | Op & Req | No8,9 | No8 | Yes | Yes | Yes7 | 1 Requires manual orchestration of function vectorization, function search, function advertisement, and agent/chat completion service invocation. This solution is available today but requires complex plumbing to integrate all the components together. 2 To supply relevant functions for each invocation of the agent or chat completion service, all plugins registered in the kernel need to be removed first. Then, a new plugin with relevant functions needs to be registered on the kernel using `kernel.Plugins.AddFromFunctions("dynamicPlugin", [relevantFunctions])` for each invocation. Alternatively, instead of removing the plugins, a new kernel can be created; however, a new instance of the agent needs to be created as well. The fact that the relevant functions will no longer be part of their original plugins and will be repackaged into a new plugin may introduce some problems, such as function name collisions and loss of the additional context provided by the original plugin. 3 To supply relevant functions for each agent invocation, a new instance of agent needs to be created per invocation because the agent uses functions defined in the `AgentDefinition.Tools` collection, which is used only at the time of agent initialization. 4 To supply relevant functions for each invocation of the agent or chat completion service, the orchestration functionality needs to provide them via the `functions` parameter of a new instance of one of the `*FunctionChoiceBehavior` class and assign that instance to the `executionSettings.FunctionChoiceBehavior` property: `executionSettings.FunctionChoiceBehavior = new AutoFunctionChoiceBehavior(functions)`. 5 Uses a function invocation filter to perform function selection and advertisement. The filter searches for the relevant functions and sets them to be advertised to the AI model via execution settings only if triggered by the invocation of the `kernel.InvokePromptAsync` function. It does nothing if triggered by other function invocations, making this option unusable in all cases except those where the `kernel.InvokePromptAsync` function is used. 6 M.E.AI Chat Client needs to be adapted to the `IChatCompletionService` interface using the `ChatClientChatCompletionService` SK adapter. 7 M.E.AI Chat Client needs to be decorated (the decorator is available in SK) so the decorator can access the function advertisement filter/function choice behavior to get the relevant functions. 8 Neither OpenAI, AzureAI, nor Bedrock agents use function choice behavior for function advertisement. Extending any of the agents to use function choice behavior does not make any sense because they do not support any other function choice behavior except auto function choice behavior. 9 Extending either OpenAI or AzureAI agents to obtain relevant functions from the provided function choice behavior will make the development experience confusing. Currently, functions can be sourced to agents from three places: agent definition, agent constructor, and kernel. Adding a fourth source will make it even more confusing. Notes: - For agents that maintain threads on the server side, getting the full context is impossible without first loading the entire thread from the server. This is not efficient and might not be supported by agents. However, the messages passed during agent invocation might be enough and can be used as context for function selection. ## Integration with Agent Memory The agent's memory model is represented by the following classes: ````csharp public sealed class AIContextPart { public string? Instructions { get; set; } public List AIFunctions { get; set; } = new(); } public abstract class AIContextBehavior { public virtual Task OnThreadCreatedAsync(string? threadId, CancellationToken ct) {...} public virtual Task OnNewMessageAsync(string? threadId, ChatMessage newMessage, CancellationToken ct) {...} public virtual Task OnThreadDeleteAsync(string? threadId, CancellationToken ct) {...} public abstract Task OnModelInvokeAsync(ICollection newMessages, CancellationToken ct); public virtual Task OnSuspendAsync(string? threadId, CancellationToken ct) {...} public virtual Task OnResumeAsync(string? threadId, CancellationToken ct) {...} } public sealed class AIContextBehaviorsManager { public AIContextBehaviorsManager(IEnumerable aiContextBehaviors) {...} public void Add(AIContextBehavior aiContextBehavior) {...} public void AddFromServiceProvider(IServiceProvider serviceProvider) {...} public async Task OnThreadCreatedAsync(string? threadId, CancellationToken ct) {...} public async Task OnThreadDeleteAsync(string threadId, CancellationToken ct) {...} public async Task OnNewMessageAsync(string? threadId, ChatMessage newMessage, CancellationToken ct) {...} public async Task OnModelInvokeAsync(ICollection newMessages, CancellationToken ct) {...} public async Task OnSuspendAsync(string? threadId, CancellationToken ct) {...} public async Task OnResumeAsync(string? threadId, CancellationToken ct) {...} } ```` An example demonstrating the model's usage: ````csharp // Create a kernel and register plugins Kernel kernel = this.CreateKernelWithChatCompletion(); kernel.Plugins.AddFromType(); // Create Mem0Behavior Mem0Behavior mem0Behavior = new(...); await mem0Behavior.ClearStoredMemoriesAsync(); // Create a chat completion agent ChatCompletionAgent agent = new(kernel, ...); // Create agent thread and add Mem0Behavior to it ChatHistoryAgentThread agentThread = new(); agentThread.AIContextBehaviors.Add(mem0Behavior); // Prompt the agent string userMessage = "Please retrieve my company report"; ChatMessageContent message = await agent.InvokeAsync(userMessage, agentThread).FirstAsync(); ```` There might be cases when there is a need to reuse an existing AI context behavior to narrow down the list of functions for non-agent scenarios, such as a chat completion service or chat client. In these cases, either the AI context behavior can be adapted to the model required by one of the options described above, or preferably the same components for vectorization and semantic search can be used to implement both the AI context behavior and the model required by one of the options described above. ## Decision Outcome During the ADR review meeting, it was decided to prioritize context-based function selection for agents by implementing an AIContextBehavior, which would perform RAG on the agent's functions. Later, upon request, the same functionality can be extended to chat completion services and M.E.AI chat clients using option 2: the M.E.AI ChatClient Decorator. ================================================ FILE: docs/decisions/0073-linq-based-text-search-filtering.md ================================================ --- status: accepted contact: alzarei date: 2025-10-25 deciders: roji, westey-m, markwallace-microsoft consulted: informed: --- # Migrate ITextSearch from Clause-Based to LINQ-Based Filtering ## Context and Problem Statement **The Challenge**: The existing `ITextSearch` interface uses clause-based `TextSearchFilter` for filtering, which creates runtime errors from property name typos, lacks IntelliSense support, and depends on obsolete `VectorSearchFilter` APIs. Modern .NET practices favor LINQ expressions for type safety and compile-time validation. **The Constraint**: We cannot introduce breaking changes. Existing code using `TextSearchFilter` must continue working. **The Question**: How do we migrate ITextSearch to modern LINQ-based filtering (`Expression>`) while maintaining backward compatibility? Issue: https://github.com/microsoft/semantic-kernel/issues/10456 ## Decision Drivers - **Type Safety**: Eliminate runtime errors from property name typos and type mismatches - **Developer Experience**: Enable IntelliSense and compile-time validation - **Technical Debt**: Remove dependency on obsolete VectorSearchFilter API - **Performance**: Eliminate unnecessary conversion overhead - **Consistency**: Align with Microsoft.Extensions.VectorData LINQ filtering patterns - **Backward Compatibility**: Maintain existing functionality for consumers - **AOT Compatibility**: Support ahead-of-time compilation scenarios - **Migration Path**: Establish clear path for eventual removal of legacy interface ## Decision Outcome **Chosen Option**: "Dual Interface Pattern". Introduce generic `ITextSearch` with LINQ filtering alongside existing `ITextSearch` marked `[Obsolete]`. We introduce **`ITextSearch`** (modern, LINQ-based) alongside the existing **`ITextSearch`** (legacy, marked `[Obsolete]`). Both interfaces coexist temporarily to provide: - ✅ **Zero breaking changes**: Existing code continues working unchanged - ✅ **Clear migration signal**: Deprecation warnings guide developers to modern interface - ✅ **Type safety for new code**: LINQ expressions provide compile-time validation - ✅ **Clean separation**: Legacy and modern paths are completely independent - ✅ **Future removal path**: Establishes timeline for eventual legacy interface elimination This is explicitly a **temporary architectural state**, not a permanent design. The dual interface pattern enables non-breaking migration while establishing a clear path to remove technical debt in a future major version. ### Pros and Cons of the Decision **Good, because**: - **Zero breaking changes**: Existing code continues working unchanged - **Clean separation**: Legacy and modern paths completely independent (no translation overhead) - **Type safety**: Generic interface provides compile-time validation and IntelliSense - **AOT compatibility**: Both interfaces are AOT-compatible (no blocking attributes) - **Clear migration path**: `[Obsolete]` attribute signals deprecation and guides users to modern interface - **Future-ready**: Establishes clear path for eventual removal of legacy interface in future major version - **Ecosystem alignment**: Gives consumers time to migrate before breaking change - **Phased implementation**: Reduces risk and enables focused code review **Bad, because**: - **Dual code paths**: Maintains two implementations per class (**temporary** during transition period) - **Legacy translation**: Non-generic path converts `FilterClause` to LINQ expression trees at runtime (**temporary**) - **Documentation burden**: Must explain when to use which interface during transition period - **Temporary complexity**: Additional maintenance burden until legacy interface removal **Key Insight**: The "bad" aspects are explicitly **temporary**. They exist only during the migration period and will be eliminated when the legacy interface is removed in a future major version. ## Implementation Sub-Decisions This section documents specific implementation choices required to realize the dual interface pattern. ### Sub-Decision 1: Architecture Overview The dual interface pattern creates two parallel execution paths: ``` ┌──────────────────────────────────────────────────────────────────────────────┐ │ ITextSearch Modernization │ └──────────────────────────────────────────────────────────────────────────────┘ ┌──────────────────────────────────────────────────────────────────────────────┐ │ Interface Layer │ ├──────────────────────────────────────────────────────────────────────────────┤ │ │ │ [Obsolete] [Modern] │ │ ITextSearch ITextSearch │ │ ├─ TextSearchOptions ├─ TextSearchOptions │ │ │ └─ TextSearchFilter │ └─ Expression> │ │ └─ No RequiresDynamicCode └─ No RequiresDynamicCode │ │ │ └──────────────────────────────────────────────────────────────────────────────┘ ┌──────────────────────────────────────────────────────────────────────────────┐ │ Implementation Layer: Two Patterns │ └──────────────────────────────────────────────────────────────────────────────┘ Pattern A: Direct LINQ Passthrough Pattern B: LINQ-to-Legacy Conversion (VectorStoreTextSearch) (BingTextSearch, GoogleTextSearch, etc.) ┌──────────────────────────────┐ ┌──────────────────────────────────┐ │ VectorStoreTextSearch │ │ BingTextSearch │ │ : ITextSearch │ │ : ITextSearch │ │ : ITextSearch │ │ : ITextSearch │ ├──────────────────────────────┤ ├──────────────────────────────────┤ │ Legacy Path: │ │ Legacy Path: │ │ TextSearchFilter │ │ TextSearchFilter │ │ ↓ │ │ ↓ │ │ BuildFilterExpression() │ │ Bing API parameters │ │ (clause → LINQ tree) │ │ ↓ │ │ ↓ │ │ HTTP GET request │ │ VectorSearchOptions.Filter │ │ │ │ ↓ │ │ Modern Path: │ │ Vector Store │ │ Expression> │ │ │ │ ↓ │ │ Modern Path: │ │ LINQ tree analysis │ │ Expression> │ │ ↓ │ │ ↓ │ │ TextSearchFilter (conversion) │ │ VectorSearchOptions.Filter │ │ ↓ │ │ (direct passthrough) │ │ Delegate to legacy path │ │ ↓ │ │ │ │ Vector Store │ │ │ └──────────────────────────────┘ └──────────────────────────────────┘ Key: Both paths use Key: Modern converts to legacy VectorSearchOptions.Filter Reuses existing implementation ``` **Key Architectural Characteristics**: 1. **Interface Layer**: Two separate interfaces: legacy (`ITextSearch`) and modern (`ITextSearch`) 2. **Pattern A (VectorStoreTextSearch)**: Both paths converge on `VectorSearchOptions.Filter` — legacy clauses are converted to LINQ expression trees via `BuildFilterExpression()`, modern path passes LINQ directly 3. **Pattern B (Web Connectors)**: LINQ expressions converted to legacy `TextSearchFilter`, then delegated to existing implementation 4. **RequiresDynamicCode**: NONE - No `[RequiresDynamicCode]` attributes on either interface or implementations 5. **AOT Compatibility**: Both interfaces are AOT-compatible (no attributes blocking compilation or runtime) ### Sub-Decision 2: Two Implementation Patterns All implementations follow the dual interface pattern, but with **two different execution strategies** based on underlying service capabilities: #### Pattern A: Direct LINQ Passthrough (VectorStoreTextSearch) VectorStoreTextSearch uses `VectorSearchOptions.Filter` (LINQ) for **both** code paths. The legacy path converts `FilterClause` values to a LINQ expression tree via `BuildFilterExpression()` — this is pure data-structure construction and fully AOT-compatible: ```csharp #pragma warning disable CS0618 // ITextSearch is obsolete - backward compatibility public sealed class VectorStoreTextSearch : ITextSearch, ITextSearch #pragma warning restore CS0618 { // ===== LEGACY PATH (Non-Generic Interface) ===== public Task> SearchAsync( string query, TextSearchOptions? searchOptions = null, CancellationToken cancellationToken = default) { var searchResponse = ExecuteVectorSearchAsync(query, searchOptions, cancellationToken); return Task.FromResult(CreateStringSearchResponse(searchResponse)); } // ===== MODERN PATH (Generic Interface) ===== Task> ITextSearch.SearchAsync( string query, TextSearchOptions? searchOptions, CancellationToken cancellationToken) { var searchResponse = ExecuteVectorSearchAsync(query, searchOptions, cancellationToken); return Task.FromResult(CreateStringSearchResponse(searchResponse)); } // Legacy path: Converts FilterClauses to LINQ expression tree private async IAsyncEnumerable> ExecuteVectorSearchAsync( string query, TextSearchOptions? searchOptions, ...) { var vectorSearchOptions = new VectorSearchOptions { Filter = searchOptions.Filter?.FilterClauses is not null ? BuildFilterExpression(searchOptions.Filter.FilterClauses) : null, }; // ... execute } // Modern path: Direct LINQ passthrough - no obsolete API private async IAsyncEnumerable> ExecuteVectorSearchAsync( string query, TextSearchOptions? searchOptions, ...) { var vectorSearchOptions = new VectorSearchOptions { Filter = searchOptions.Filter, // Direct LINQ - no conversion }; // ... execute } } ``` #### Pattern B: LINQ-to-Legacy Conversion (Web Search Connectors) BingTextSearch, GoogleTextSearch, TavilyTextSearch, BraveTextSearch convert generic interface calls to legacy format: ```csharp #pragma warning disable CS0618 // ITextSearch is obsolete public sealed class BingTextSearch : ITextSearch, ITextSearch #pragma warning restore CS0618 { // ===== LEGACY PATH (Non-Generic Interface) ===== public Task> SearchAsync( string query, TextSearchOptions? searchOptions = null, CancellationToken cancellationToken = default) { // Direct Bing API call with TextSearchFilter // ... existing logic } // ===== MODERN PATH (Generic Interface) ===== Task> ITextSearch.SearchAsync( string query, TextSearchOptions? searchOptions, CancellationToken cancellationToken) { // Convert generic options to legacy format var legacyOptions = searchOptions != null ? ConvertToLegacyOptions(searchOptions) : new TextSearchOptions(); // Delegate to existing legacy implementation return this.SearchAsync(query, legacyOptions, cancellationToken); } // LINQ-to-TextSearchFilter conversion private static TextSearchOptions ConvertToLegacyOptions( TextSearchOptions genericOptions) { return new TextSearchOptions { Top = genericOptions.Top, Skip = genericOptions.Skip, Filter = genericOptions.Filter != null ? ConvertLinqExpressionToBingFilter(genericOptions.Filter) : null }; } // Expression tree analysis and mapping to Bing API syntax private static TextSearchFilter ConvertLinqExpressionToBingFilter( Expression> linqExpression) { var filter = new TextSearchFilter(); // Recursively process expression tree: // - Equality (==) → language:en // - Inequality (!=) → -language:fr // - Contains() → intitle:"AI" or inbody:"term" // - AND (&&) → multiple filter clauses ProcessExpression(linqExpression.Body, filter); return filter; } } ``` **Key Differences**: | Aspect | Pattern A (VectorStoreTextSearch) | Pattern B (Web Connectors) | | ---------------------- | -------------------------------------------- | -------------------------------------------- | | **Execution Paths** | Two independent paths | Modern converts to legacy | | **Conversion Layer** | NO conversion | LINQ → TextSearchFilter | | **Legacy Path** | Uses obsolete `VectorSearchFilter.OldFilter` | Uses existing `TextSearchFilter` directly | | **Modern Path** | Uses `VectorSearchOptions.Filter` directly | Converts LINQ then delegates to legacy path | | **Performance** | Zero overhead (direct passthrough) | Conversion overhead acceptable (network I/O) | | **Underlying Support** | Native LINQ support | API-specific parameter mapping | **Why Two Patterns?** 1. **VectorStoreTextSearch**: Underlying vector store natively supports LINQ expressions via `VectorSearchOptions.Filter`. Direct passthrough eliminates overhead. 2. **Web Connectors**: Underlying APIs (Bing, Google) don't accept LINQ. Conversion to TextSearchFilter then to API parameters maintains compatibility. **Note**: Both patterns maintain dual code paths (legacy + modern) as a **temporary migration strategy**. Once the obsolete `ITextSearch` interface is removed in a future major version, only the modern LINQ path will remain, eliminating the dual implementation complexity. ### Sub-Decision 3: AOT Compatibility Strategy Both interfaces are designed to be AOT-compatible with **no `[RequiresDynamicCode]` attributes**: **Non-Generic Interface (`ITextSearch`)**: - ✅ Fully AOT-compatible - Uses `TextSearchFilter` (clause-based, no LINQ) - No dynamic code generation required **Generic Interface (`ITextSearch`)**: - ✅ AOT-compatible - Uses LINQ expressions - Processed via **expression tree analysis**, not dynamic code generation - No `[RequiresDynamicCode]` attribute required **LINQ Expression Processing**: ```csharp // Simple equality - AOT-compatible filter = doc => doc.Department == "HR" && doc.IsActive // Complex expressions - AOT-compatible (expression tree analysis) filter = doc => doc.Tags.Any(tag => tag.Contains("urgent")) ``` **AOT Compatibility Matrix**: | Scenario | ITextSearch | ITextSearch<TRecord> | Notes | | ------------------------------ | ----------------- | -------------------------- | ----------------------------- | | Simple searches (no filtering) | ✅ AOT-compatible | ✅ AOT-compatible | No dynamic code needed | | TextSearchFilter-based | ✅ AOT-compatible | N/A | Legacy clause-based filtering | | Simple LINQ (equality) | N/A | ✅ AOT-compatible | Expression tree analysis | | Complex LINQ (Contains, Any) | N/A | ✅ AOT-compatible | Expression tree analysis | ### Sub-Decision 4: Contains() Support for Web Search Connectors **Context**: The `ITextSearch` interface supports LINQ expressions, including `Title.Contains("value")` patterns. Different search engine APIs have varying capabilities: - **Bing**: Native advanced search operators (`intitle:`, `inbody:`, `url:`) - **Google**: Specialized API parameters (`orTerms` for additional search terms) - **Brave/Tavily**: General search APIs without field-specific operators **Decision**: Implement `Title.Contains()` support using **query enhancement** for Brave and Tavily search engines: 1. **SearchQueryFilterClause**: New filter clause type that adds terms to the search query rather than filtering results 2. **Query Enhancement Pattern**: Extract terms from `SearchQueryFilterClause` instances and append to base search query 3. **Dual Processing**: Handle `SearchQueryFilterClause` differently from regular filter clauses **Implementation Pattern**: ```csharp // LINQ Expression: results.Where(r => r.Title.Contains("AI")) // Converts to: new SearchQueryFilterClause("AI") // Query Enhancement: "original query" + " AI" ``` **Alternatives Considered**: 1. **Direct API Parameters**: Not available in Brave/Tavily APIs 2. **Post-Search Filtering**: Would reduce result relevance and performance 3. **NotSupportedException**: Would limit LINQ expression capabilities **Consequences**: - ✅ Consistent LINQ expression support across search engines - ✅ Enhanced search relevance by modifying query rather than filtering results - ✅ Extensible pattern for future Contains() implementations - ⚠️ Different implementation approaches across search engines (consistency concern) - ⚠️ Additional complexity in filter clause processing ### Sub-Decision 5: SearchQueryFilterClause Location and FilterClause Constructor Visibility **Context**: `SearchQueryFilterClause` is used only by web search connectors (Brave, Tavily) in `Plugins.Web`. To minimize public API surface, it should reside in the same assembly as its consumers. **Problem**: `FilterClause` base class originally had an **internal constructor**, preventing inheritance outside the `VectorData.Abstractions` assembly: ```csharp public abstract class FilterClause { internal FilterClause() // ← Blocked external inheritance } ``` Moving `SearchQueryFilterClause` to `Plugins.Web` failed with: ``` error CS0122: 'FilterClause.FilterClause()' is inaccessible due to its protection level ``` **Decision**: Make `FilterClause` constructor **`protected`** and move `SearchQueryFilterClause` to `Plugins.Web` as **`internal sealed`**. ```csharp // In VectorData.Abstractions public abstract class FilterClause { protected FilterClause() // internal → protected } // In Plugins.Web internal sealed class SearchQueryFilterClause : FilterClause ``` **Rationale**: - **Minimal API surface**: `SearchQueryFilterClause` stays internal (not public) - **Controlled extensibility**: `protected` allows inheritance but maintains encapsulation - **Correct location**: Class lives in `Plugins.Web` where it's actually used - **Standard pattern**: `protected` constructors are common for abstract base classes **Alternatives Considered**: 1. **Keep internal constructor + public SearchQueryFilterClause in VectorData**: Adds unnecessary public API 2. **Internal + InternalsVisibleTo**: Causes 200 CS0436 type conflict errors in CI 3. **Public constructor**: Too permissive, allows unrestricted external filter types 4. **Don't inherit from FilterClause**: Breaks established pattern, loses type safety **Consequences**: - ✅ Minimal public API impact (only constructor visibility change on existing abstract class) - ✅ `SearchQueryFilterClause` remains internal implementation detail - ✅ Enables future filter clause implementations outside VectorData assembly - ✅ Clean implementation with no workarounds ### Sub-Decision 6: Obsolete Marking Strategy **Decision**: Mark the original `ITextSearch` interface with `[Obsolete]` attribute immediately: ```csharp [Obsolete("ITextSearch is deprecated. Use ITextSearch with LINQ filtering instead.")] public interface ITextSearch { // Legacy implementation } ``` **Purpose of Obsolete Marking**: 1. **Developer Guidance**: Compile-time warnings inform developers that this API should not be used in new code 2. **Migration Signal**: Clear indication that this interface will be removed in a future major version 3. **Ecosystem Preparation**: Gives library consumers advance notice to plan migration work 4. **IDE Support**: Modern IDEs display deprecation warnings and suggest alternatives **Why Mark as Obsolete Now** (rather than waiting): - Prevents new code from adopting legacy patterns - Starts ecosystem migration clock immediately - Aligns with .NET best practices for API evolution - Allows sufficient migration period before actual removal (typically 1-2 major versions) ## Migration Strategy This decision implements a **deliberate three-phase migration path** from legacy clause-based filtering to modern LINQ-based filtering: ### Phase 1: Transition State (Current - Implemented in This ADR) - ✅ `ITextSearch` introduced with LINQ filtering (modern, recommended) - ✅ `ITextSearch` marked `[Obsolete]` with deprecation warning - ✅ Both interfaces coexist for backward compatibility - ✅ All implementations support both interfaces - ✅ Documentation updated to recommend generic interface **Key Point**: Marking `ITextSearch` as `[Obsolete]` serves dual purposes: - **Immediate**: Signals to developers that this interface is deprecated and should not be used in new code - **Long-term**: Establishes clear path for eventual removal, allowing ecosystem to migrate before breaking change ### Phase 2: Increased Deprecation (Future - Next Major Version) - Increase obsolete warning severity (`ObsoleteAttribute` with `error: true`) - Add removal timeline to documentation - Final migration period for stragglers - Communication campaign to ecosystem ### Phase 3: Legacy Removal (Eventually - Future Major Version) - **BREAKING CHANGE**: Remove `ITextSearch` interface entirely - Remove public API usage of `TextSearchFilter` in `TextSearchOptions` - Remove `VectorSearchFilter.OldFilter` - Remove all legacy public API code paths - Single modern interface with LINQ expressions remains - **Note**: `TextSearchFilter` and `FilterClause` types retained internally as LINQ translation layer for web plugins only; vector stores use LINQ expressions directly via `VectorSearchOptions.Filter` **Estimated Timeline**: Phase 2 in next major version (e.g., SK 2.0), Phase 3 in subsequent major version (e.g., SK 3.0). This gives ecosystem minimum 1-2 years to migrate. ### Migration Path Diagram ``` Phase 1 (Current): ├─ Both interfaces coexist ├─ Legacy ITextSearch marked [Obsolete] ├─ Deprecation warnings guide users to ITextSearch └─ All implementations support both interfaces Phase 2 (Future): ├─ Increase deprecation severity ├─ Add removal timeline to warnings └─ Documentation emphasizes migration Phase 3 (Eventually): ├─ Remove ITextSearch interface ├─ Remove TextSearchFilter class ├─ Remove VectorSearchFilter.OldFilter └─ Single interface with LINQ expressions ``` The dual interface pattern is explicitly a **temporary architectural state**, not a permanent design. It provides: - Non-breaking migration for existing consumers - Clear migration signals via deprecation warnings - Time for ecosystem adoption before removal - Ability to remove technical debt in future major version ## Appendix: Alternative Options Considered This section documents alternative approaches that were evaluated but not selected. ### Option 1: Direct LINQ Replacement (Native LINQ Only) Replace TextSearchFilter entirely with Expression>. Remove non-generic interface completely. **Evaluation**: - Good, because uniform API design with strong type safety - Good, because eliminates all technical debt immediately - Good, because best long-term architecture with full expression support - Good, because aligns with Microsoft.Extensions.VectorData patterns - Bad, because **BREAKING CHANGE**: requires all consumers to migrate - Bad, because high disruption cost for transitive dependencies **Why Not Chosen**: Breaking change unacceptable for stable API. ### Option 2: Native LINQ + Translation Layer Keep both interfaces but convert TextSearchFilter to LINQ internally. **Evaluation**: - Good, because avoids obsolete API usage (no VectorSearchFilter dependency) - Good, because reuses single implementation path - Good, because building expression trees is pure data-structure construction, fully AOT-compatible - Bad, because introduces conversion overhead (though minimal for simple equality clauses) **Update**: This option was originally rejected based on an incorrect assessment that `RequiresDynamicCode` would cascade to all TextSearch APIs. In fact, **building** expression trees (`Expression.Property`, `Expression.Equal`, `Expression.Lambda`) is fully AOT-compatible — only **compiling** expression trees (`Expression.Compile()`) requires dynamic code generation. Since MEVD's `VectorSearchOptions.Filter` analyzes the expression tree without compiling it, there is no AOT incompatibility. This approach was adopted in the `VectorStoreTextSearch` legacy path to enable MEVD to remove its obsolete `OldFilter` property before publishing 1.0 provider versions. ### Option 3: Adapter Pattern Implement generic interface as wrapper over existing implementations. **Evaluation**: - Good, because minimal code changes to existing implementations - Good, because clear separation of concerns - Bad, because adds unnecessary abstraction layer - Bad, because conversion overhead for every operation - Bad, because doesn't address underlying technical debt **Why Not Chosen**: Doesn't solve the core problem of obsolete API dependency. ### Option 4: Gradual Migration (Deprecate and Introduce) Deprecate TextSearchFilter and introduce LINQ alongside within same interface. **Evaluation**: - Good, because single interface to maintain - Bad, because creates ambiguity about which filter mechanism to use - Bad, because requires complex runtime type checking - Bad, because doesn't provide clear migration path **Why Not Chosen**: Ambiguous API design and poor developer experience. ## More Information ### Related Decisions - ADR-0058: Updated Vector Search Design (establishes LINQ-based filtering foundation) - ADR-0059: Text Search Abstraction (defines ITextSearch interface requirements) ### Security Considerations LINQ expressions processed on server side only. No user-supplied expression execution. Expression tree analysis validates supported operations before execution. Unsupported operations throw ArgumentException with clear error messages. ### Breaking Change Analysis No immediate breaking changes: - Existing TextSearchFilter-based code continues working - New generic interface additive only - Migration path documented - Deprecation warnings guide future migration ================================================ FILE: docs/decisions/README.md ================================================ # Architectural Decision Records (ADRs) An Architectural Decision (AD) is a justified software design choice that addresses a functional or non-functional requirement that is architecturally significant.

Keep the list of `deciders` short. You can also list people who were `consulted` or `informed` about the decision. 3. For each option list the good, neutral and bad aspects of each considered alternative. 1. Detailed investigations can be included in the `More Information` section inline or as links to external documents. 4. Share your PR with the deciders and other interested parties. 1. Deciders must be listed as required reviewers. 2. The status must be updated to `accepted` once a decision is agreed and the date must also be updated. 3. Approval of the decision is captured using PR approval. 5. Decisions can be changed later and superseded by a new ADR. In this case it is useful to record any negative outcomes in the original ADR. ================================================ FILE: docs/decisions/adr-short-template.md ================================================ --- # These are optional elements.

using Microsoft.SemanticKernel.Connectors.OpenAI; var builder = Kernel.CreateBuilder(); builder.AddAzureOpenAIChatCompletion( "gpt-35-turbo", // Azure OpenAI Deployment Name "https://contoso.openai.azure.com/", // Azure OpenAI Endpoint "...your Azure OpenAI Key..."); // Azure OpenAI Key // Alternative using OpenAI //builder.AddOpenAIChatCompletion( // "gpt-3.5-turbo", // OpenAI Model name // "...your OpenAI API Key..."); // OpenAI API Key var kernel = builder.Build(); var prompt = @"{{$input}} One line TLDR with the fewest words."; var summarize = kernel.CreateFunctionFromPrompt(prompt, executionSettings: new OpenAIPromptExecutionSettings { MaxTokens = 100 }); string text1 = @" 1st Law of Thermodynamics - Energy cannot be created or destroyed. 2nd Law of Thermodynamics - For a spontaneous process, the entropy of the universe increases. 3rd Law of Thermodynamics - A perfect crystal at zero Kelvin has zero entropy."; string text2 = @" 1. An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force. 2. The acceleration of an object depends on the mass of the object and the amount of force applied. 3. Whenever one object exerts a force on another object, the second object exerts an equal and opposite on the first."; Console.WriteLine(await kernel.InvokeAsync(summarize, new() { ["input"] = text1 })); Console.WriteLine(await kernel.InvokeAsync(summarize, new() { ["input"] = text2 })); // Output: // Energy conserved, entropy increases, zero entropy at 0K. // Objects move in response to forces. ``` # Semantic Kernel Notebooks The repository contains also a few C# Jupyter notebooks that demonstrates how to get started with the Semantic Kernel.

If you are interested in contributing to the development of a model, please use the attached links to the GitHub issues and comment that you're wanting to help. ## Supported deployment types In the core Semantic Kernel repo, we plan on supporting up to four deployment types of each model: - Dedicated API endpoints (e.g., OpenAI's APIs, Mistral.AI, and Google Gemini) - Azure AI deployments via the [model catalog](https://learn.microsoft.com/en-us/azure/ai-studio/how-to/model-catalog) - Local deployments via [Ollama](https://ollama.ai/) - Hugging face deployment using the [Hugging Face inference API](https://huggingface.co/docs/api-inference/index) To support these different deployment types, we will follow a similar pattern to the Azure OpenAI and OpenAI connectors. Each connector uses the same underlying model and abstractions, but the connector constructors may take different parameters. For example, the Azure OpenAI connector expects an Azure endpoint and key, whereas the OpenAI connector expects an OpenAI organization ID and API key. If there is another deployment type you'd like to see supported, please open an issue. We'll either work with you to add support for it or help you create a custom repository and NuGet package for your use case. ## Planned models The following models are currently prioritized for development. If you'd like to see a model added to this list, please open an issue. If you'd like to contribute to the development of a model, please comment on the issue that you're wanting to help. Please note that not all of the model interfaces are defined yet. As part of contributing a new model, we'll work with you to define the interface and then implement it. As part of implementing the connector, you may also determine that the currently planned interface isn't the best fit for the model. If that's the case, we'll work with you to update the interface. ### OpenAI | Priority | Model | Status | Interface | Deployment type | GitHub issue | Developer | Reviewer | | -------- |

================================================ FILE: dotnet/docs/OPENAI-CONNECTOR-MIGRATION.md ================================================ # OpenAI Connector Migration Guide This manual prepares you for the migration of your OpenAI Connector to the new OpenAI Connector. The new OpenAI Connector is a complete rewrite of the existing OpenAI Connector and is designed to be more efficient, reliable, and scalable. This manual will guide you through the migration process and help you understand the changes that have been made to the OpenAI Connector. ## 1. Package Setup when Using Azure If you are working with Azure and or OpenAI public APIs, you will need to change the package from `Microsoft.SemanticKernel.Connectors.OpenAI` to `Microsoft.SemanticKernel.Connectors.AzureOpenAI`, > [!IMPORTANT] > The `Microsoft.SemanticKernel.Connectors.AzureOpenAI` package depends on the `Microsoft.SemanticKernel.Connectors.OpenAI` package so there's no need to add both to your project when using `OpenAI` related types. ```diff - // Before - using Microsoft.SemanticKernel.Connectors.OpenAI; + After + using Microsoft.SemanticKernel.Connectors.AzureOpenAI; ``` ### 1.1 AzureOpenAIClient When using Azure with OpenAI, before where you were using `OpenAIClient` you will need to update your code to use the new `AzureOpenAIClient` type. ### 1.2 Services All services below now belong to the `Microsoft.SemanticKernel.Connectors.AzureOpenAI` namespace. - `AzureOpenAIAudioToTextService` - `AzureOpenAIChatCompletionService` - `AzureOpenAITextEmbeddingGenerationService` - `AzureOpenAITextToAudioService` - `AzureOpenAITextToImageService` ## 2. Text Generation Deprecated The latest `OpenAI` SDK does not support text generation modality, when migrating to their underlying SDK we had to drop the support and removed `TextGeneration` specific services but the existing `ChatCompletion` ones still supports (implements `ITextGenerationService`). If you were using any of the `OpenAITextGenerationService` or `AzureOpenAITextGenerationService` you will need to update your code to target a chat completion model instead, using `OpenAIChatCompletionService` or `AzureOpenAIChatCompletionService` instead. > [!NOTE] > OpenAI and AzureOpenAI `ChatCompletion` services also implement the `ITextGenerationService` interface and that may not require any changes to your code if you were targeting the `ITextGenerationService` interface. tags: `OpenAITextGenerationService`,`AzureOpenAITextGenerationService`, `AddOpenAITextGeneration`,`AddAzureOpenAITextGeneration` ## 3. ChatCompletion Multiple Choices Deprecated The latest `OpenAI` SDK does not support multiple choices, when migrating to their underlying SDK we had to drop the support and removed `ResultsPerPrompt` also from the `OpenAIPromptExecutionSettings`. tags: `ResultsPerPrompt`,`results_per_prompt` ## 4. OpenAI File Service Deprecation The `OpenAIFileService` was deprecated in the latest version of the OpenAI Connector. We strongly recommend to update your code to use the new `OpenAIClient.GetFileClient()` for file management operations. ## 5. OpenAI ChatCompletion custom endpoint The `OpenAIChatCompletionService` **experimental** constructor for custom endpoints will not attempt to auto-correct the endpoint and use it as is. We have the two only specific cases where we attempted to auto-correct the endpoint. 1. If you provided `chat/completions` path before. Now those need to be removed as they are added automatically to the end of your original endpoint by `OpenAI SDK`. ```diff - http://any-host-and-port/v1/chat/completions + http://any-host-and-port/v1 ``` 2. If you provided a custom endpoint without any path. We won't be adding the `v1/` as the first path. Now the `v1` path needs to provided as part of your endpoint. ```diff - http://any-host-and-port/ + http://any-host-and-port/v1 ``` ## 6. SemanticKernel MetaPackage To be retro compatible with the new OpenAI and AzureOpenAI Connectors, our `Microsoft.SemanticKernel` meta package changed its dependency to use the new `Microsoft.SemanticKernel.Connectors.AzureOpenAI` package that depends on the `Microsoft.SemanticKernel.Connectors.OpenAI` package. This way if you are using the metapackage, no change is needed to get access to `Azure` related types. ## 7. Contents ### 7.1 OpenAIChatMessageContent - The `Tools` property type has changed from `IReadOnlyList` to `IReadOnlyList`. - Inner content type has changed from `ChatCompletionsFunctionToolCall` to `ChatToolCall`. - Metadata type `FunctionToolCalls` has changed from `IEnumerable` to `IEnumerable`. ### 7.2 OpenAIStreamingChatMessageContent - The `FinishReason` property type has changed from `CompletionsFinishReason` to `FinishReason`. - The `ToolCallUpdate` property has been renamed to `ToolCallUpdates` and its type has changed from `StreamingToolCallUpdate?` to `IReadOnlyList?`. - The `AuthorName` property is not initialized because it's not provided by the underlying library anymore. ## 7.3 Metrics for AzureOpenAI Connector The meter `s_meter = new("Microsoft.SemanticKernel.Connectors.OpenAI");` and the relevant counters still have old names that contain "openai" in them, such as: - `semantic_kernel.connectors.openai.tokens.prompt` - `semantic_kernel.connectors.openai.tokens.completion` - `semantic_kernel.connectors.openai.tokens.total` ## 8. Using Azure with your data (Data Sources) With the new `AzureOpenAIClient`, you can now specify your datasource thru the options and that requires a small change in your code to the new type. Before ```csharp var promptExecutionSettings = new OpenAIPromptExecutionSettings { AzureChatExtensionsOptions = new AzureChatExtensionsOptions { Extensions = [ new AzureSearchChatExtensionConfiguration { SearchEndpoint = new Uri(TestConfiguration.AzureAISearch.Endpoint), Authentication = new OnYourDataApiKeyAuthenticationOptions(TestConfiguration.AzureAISearch.ApiKey), IndexName = TestConfiguration.AzureAISearch.IndexName }] }; }; ``` After ```csharp var promptExecutionSettings = new AzureOpenAIPromptExecutionSettings { AzureChatDataSource = new AzureSearchChatDataSource { Endpoint = new Uri(TestConfiguration.AzureAISearch.Endpoint), Authentication = DataSourceAuthentication.FromApiKey(TestConfiguration.AzureAISearch.ApiKey), IndexName = TestConfiguration.AzureAISearch.IndexName } }; ``` ## 9. Breaking glass scenarios Breaking glass scenarios are scenarios where you may need to update your code to use the new OpenAI Connector. Below are some of the breaking changes that you may need to be aware of. #### 9.1 KernelContent Metadata Some of the keys in the content metadata dictionary have changed, you will need to update your code to when using the previous key names. - `Created` -> `CreatedAt` #### 9.2 Prompt Filter Results The `PromptFilterResults` metadata type has changed from `IReadOnlyList` to `ContentFilterResultForPrompt`. #### 9.3 Content Filter Results The `ContentFilterResultsForPrompt` type has changed from `ContentFilterResultsForChoice` to `ContentFilterResultForResponse`. #### 9.4 Finish Reason The FinishReason metadata string value has changed from `stop` to `Stop` #### 9.5 Tool Calls The ToolCalls metadata string value has changed from `tool_calls` to `ToolCalls` #### 9.6 LogProbs / Log Probability Info The `LogProbabilityInfo` type has changed from `ChatChoiceLogProbabilityInfo` to `IReadOnlyList`. #### 9.7 Finish Details, Index, and Enhancements All of above have been removed. #### 9.8 Token Usage The Token usage naming convention from `OpenAI` changed from `Completion`, `Prompt` tokens to `Output` and `Input` respectively. You will need to update your code to use the new naming. The type also changed from `CompletionsUsage` to `ChatTokenUsage`. [Example of Token Usage Metadata Changes](https://github.com/microsoft/semantic-kernel/pull/7151/files#diff-a323107b9f8dc8559a83e50080c6e34551ddf6d9d770197a473f249589e8fb47) ```diff - Before - var usage = FunctionResult.Metadata?["Usage"] as CompletionsUsage; - var completionTokesn = usage?.CompletionTokens ?? 0; - var promptTokens = usage?.PromptTokens ?? 0; + After + var usage = FunctionResult.Metadata?["Usage"] as ChatTokenUsage; + var promptTokens = usage?.InputTokens ?? 0; + var completionTokens = completionTokens: usage?.OutputTokens ?? 0; totalTokens: usage?.TotalTokens ?? 0; ``` #### 9.9 OpenAIClient The `OpenAIClient` type previously was a Azure specific namespace type but now it is an `OpenAI` SDK namespace type, you will need to update your code to use the new `OpenAIClient` type. When using Azure, you will need to update your code to use the new `AzureOpenAIClient` type. #### 9.10 Pipeline Configuration The new `OpenAI` SDK uses a different pipeline configuration, and has a dependency on `System.ClientModel` package. You will need to update your code to use the new `HttpClientPipelineTransport` transport configuration where before you were using `HttpClientTransport` from `Azure.Core.Pipeline`. [Example of Pipeline Configuration](https://github.com/microsoft/semantic-kernel/pull/7151/files#diff-fab02d9a75bf43cb57f71dddc920c3f72882acf83fb125d8cad963a643d26eb3) ```diff var clientOptions = new OpenAIClientOptions { - // Before: From Azure.Core.Pipeline - Transport = new HttpClientTransport(httpClient), + // After: From OpenAI SDK -> System.ClientModel + Transport = new HttpClientPipelineTransport(httpClient), }; ``` ================================================ FILE: dotnet/docs/TELEMETRY.md ================================================ # Telemetry Telemetry in Semantic Kernel (SK) .NET implementation includes _logging_, _metering_ and _tracing_. The code is instrumented using native .NET instrumentation tools, which means that it's possible to use different monitoring platforms (e.g. Application Insights, Aspire dashboard, Prometheus, Grafana etc.). Code example using Application Insights can be found [here](../samples/Demos/TelemetryWithAppInsights/). ## Logging The logging mechanism in this project relies on the `ILogger` interface from the `Microsoft.Extensions.Logging` namespace. Recent updates have introduced enhancements to the logger creation process. Instead of directly using the `ILogger` interface, instances of `ILogger` are now recommended to be created through an `ILoggerFactory` configured through a `ServiceCollection`. By employing the `ILoggerFactory` approach, logger instances are generated with precise type information, facilitating more accurate logging and streamlined control over log filtering across various classes. Log levels used in SK: - Trace - this type of logs **should not be enabled in production environments**, since it may contain sensitive data. It can be useful in test environments for better observability. Logged information includes: - Goal/Ask to create a plan - Prompt (template and rendered version) for AI to create a plan - Created plan with function arguments (arguments may contain sensitive data) - Prompt (template and rendered version) for AI to execute a function - Arguments to functions (arguments may contain sensitive data) - Debug - contains more detailed messages without sensitive data. Can be enabled in production environments. - Information (default) - log level that is enabled by default and provides information about general flow of the application. Contains following data: - AI model used to create a plan - Plan creation status (Success/Failed) - Plan creation execution time (in seconds) - Created plan without function arguments - AI model used to execute a function - Function execution status (Success/Failed) - Function execution time (in seconds) - Warning - includes information about unusual events that don't cause the application to fail. - Error - used for logging exception details. ### Examples Enable logging for Kernel instance: ```csharp IKernelBuilder builder = Kernel.CreateBuilder(); // Assuming loggerFactory is already defined. builder.Services.AddSingleton(loggerFactory); ... var kernel = builder.Build(); ``` All kernel functions and planners will be instrumented. It includes _logs_, _metering_ and _tracing_. ### Log Filtering Configuration Log filtering configuration has been refined to strike a balance between visibility and relevance: ```csharp using var loggerFactory = LoggerFactory.Create(builder => { // Add OpenTelemetry as a logging provider builder.AddOpenTelemetry(options => { // Assuming connectionString is already defined. options.AddAzureMonitorLogExporter(options => options.ConnectionString = connectionString); // Format log messages. This is default to false. options.IncludeFormattedMessage = true; }); builder.AddFilter("Microsoft", LogLevel.Warning); builder.AddFilter("Microsoft.SemanticKernel", LogLevel.Information); } ``` > Read more at: https://github.com/open-telemetry/opentelemetry-dotnet/blob/main/docs/logs/customizing-the-sdk/README.md ## Metering Metering is implemented with `Meter` class from `System.Diagnostics.Metrics` namespace. Available meters: - _Microsoft.SemanticKernel.Planning_ - contains all metrics related to planning. List of metrics: - `semantic_kernel.planning.create_plan.duration` (Histogram) - execution time of plan creation (in seconds) - `semantic_kernel.planning.invoke_plan.duration` (Histogram) - execution time of plan execution (in seconds) - _Microsoft.SemanticKernel_ - captures metrics for `KernelFunction`. List of metrics: - `semantic_kernel.function.invocation.duration` (Histogram) - function execution time (in seconds) - `semantic_kernel.function.streaming.duration` (Histogram) - function streaming execution time (in seconds) - `semantic_kernel.function.invocation.token_usage.prompt` (Histogram) - number of prompt token usage (only for `KernelFunctionFromPrompt`) - `semantic_kernel.function.invocation.token_usage.completion` (Histogram) - number of completion token usage (only for `KernelFunctionFromPrompt`) - _Microsoft.SemanticKernel.Connectors.OpenAI_ - captures metrics for OpenAI functionality. List of metrics: - `semantic_kernel.connectors.openai.tokens.prompt` (Counter) - number of prompt tokens used. - `semantic_kernel.connectors.openai.tokens.completion` (Counter) - number of completion tokens used. - `semantic_kernel.connectors.openai.tokens.total` (Counter) - total number of tokens used. Measurements will be associated with tags that will allow data to be categorized for analysis: ```csharp TagList tags = new() { { "semantic_kernel.function.name", this.Name } }; s_invocationDuration.Record(duration.TotalSeconds, in tags); ``` ### [Examples](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/samples/Demos/TelemetryWithAppInsights/Program.cs) Depending on monitoring tool, there are different ways how to subscribe to available meters. Following example shows how to subscribe to available meters and export metrics to Application Insights using `OpenTelemetry.Sdk`: ```csharp using var meterProvider = Sdk.CreateMeterProviderBuilder() .AddMeter("Microsoft.SemanticKernel*") .AddAzureMonitorMetricExporter(options => options.ConnectionString = connectionString) .Build(); ``` > Read more at: https://learn.microsoft.com/en-us/azure/azure-monitor/app/opentelemetry-enable?tabs=net > Read more at: https://github.com/open-telemetry/opentelemetry-dotnet/blob/main/docs/metrics/customizing-the-sdk/README.md ## Tracing Tracing is implemented with `Activity` class from `System.Diagnostics` namespace. Available activity sources: - _Microsoft.SemanticKernel.Planning_ - creates activities for all planners. - _Microsoft.SemanticKernel_ - creates activities for `KernelFunction` as well as requests to models. ### Examples Subscribe to available activity sources using `OpenTelemetry.Sdk`: ```csharp using var traceProvider = Sdk.CreateTracerProviderBuilder() .AddSource("Microsoft.SemanticKernel*") .AddAzureMonitorTraceExporter(options => options.ConnectionString = connectionString) .Build(); ``` > Read more at: https://github.com/open-telemetry/opentelemetry-dotnet/blob/main/docs/trace/customizing-the-sdk/README.md ================================================ FILE: dotnet/format.ps1 ================================================ $ErrorActionPreference = 'Stop' # --- config ------------------------------------------------------- $exclude = @( 'Experimental.Orchestration.Flow.csproj', 'Experimental.Orchestration.Flow.UnitTests.csproj', 'Experimental.Orchestration.Flow.IntegrationTests.csproj' ) $repoRoot = (git rev-parse --show-toplevel).Trim() $repoRoot = (Resolve-Path $repoRoot).Path # canonical form pushd $repoRoot # ----------------------------------------------------------------- $targets = git diff --name-only main..HEAD | ForEach-Object { $dir = Split-Path (Join-Path $repoRoot $_) -Parent # << absolute while ($dir -and $dir -ne $repoRoot) { $proj = Get-ChildItem -LiteralPath $dir -Filter *.csproj -File -ErrorAction Ignore | Select-Object -First 1 if ($proj) { if ($exclude -notcontains $proj.Name) { $proj.FullName } break } $dir = Split-Path $dir -Parent } } | Sort-Object -Unique popd if (-not $targets) { # $targets = Get-ChildItem $repoRoot -Recurse -Filter *.slnx | # Select-Object -Expand FullName Write-Host "No code changes found" } foreach ($t in $targets) { Write-Host "Formatting $t" } foreach ($t in $targets) { dotnet format --no-restore --verbosity diag $t } ================================================ FILE: dotnet/global.json ================================================ { "sdk": { "version": "10.0.100", "rollForward": "major", "allowPrerelease": false } } ================================================ FILE: dotnet/notebooks/0-AI-settings.ipynb ================================================ { "cells": [ { "attachments": {}, "cell_type": "markdown", "metadata": {}, "source": [ "Before starting we need to setup some configuration, like which AI backend to use.\n", "\n", "When using the kernel for AI requests, the kernel needs some settings like URL and\n", "credentials to the AI models.

The notebooks are organized in order of increasing complexity. To run the notebooks, we recommend the following steps: - [Install .NET 10](https://dotnet.microsoft.com/download/dotnet/10.0) - [Install Visual Studio Code (VS Code)](https://code.visualstudio.com) - Launch VS Code and [install the "Polyglot" extension](https://marketplace.visualstudio.com/items?itemName=ms-dotnettools.dotnet-interactive-vscode). Min version required: v1.0.4606021 (Dec 2023). The steps above should be sufficient, you can now **open all the C# notebooks in VS Code**.

You can create the file manually or run [the Setup notebook](0-AI-settings.ipynb). For Azure OpenAI: ```json { "type": "azure", "model": "...", // Azure OpenAI Deployment Name "endpoint": "...", // Azure OpenAI endpoint "apikey": "..." // Azure OpenAI key } ``` For OpenAI: ```json { "type": "openai", "model": "gpt-3.5-turbo", // OpenAI model name "apikey": "...", // OpenAI API Key "org": "" // only for OpenAI accounts with multiple orgs } ``` If you need an Azure OpenAI key, go [here](https://learn.microsoft.com/en-us/azure/cognitive-services/openai/quickstart?pivots=rest-api). If you need an OpenAI key, go [here](https://platform.openai.com/account/api-keys) # Topics Before starting, make sure you configured `config/settings.json`, see the previous section. For a quick dive, look at the [getting started notebook](00-getting-started.ipynb). 1. [Loading and configuring Semantic Kernel](01-basic-loading-the-kernel.ipynb) 2. [Running AI prompts from file](02-running-prompts-from-file.ipynb) 3. [Creating Semantic Functions at runtime (i.e. inline functions)](03-semantic-function-inline.ipynb) 4. [Using Kernel Arguments to Build a Chat Experience](04-kernel-arguments-chat.ipynb) 5. [Introduction to the Function Calling](05-using-function-calling.ipynb) 6. [Vector Stores and Embeddings](06-vector-stores-and-embeddings.ipynb) 7. [Creating images with DALL-E 3](07-DALL-E-3.ipynb) 8. [Chatting with ChatGPT and Images](08-chatGPT-with-DALL-E-3.ipynb) 9. [BingSearch using Kernel](09-RAG-with-BingSearch.ipynb) # Run notebooks in the browser with JupyterLab You can run the notebooks also in the browser with JupyterLab. These steps should be sufficient to start: Install Python 3, Pip and .NET 10 in your system, then: pip install jupyterlab dotnet tool install -g Microsoft.dotnet-interactive dotnet tool update -g Microsoft.dotnet-interactive dotnet interactive jupyter install This command will confirm that Jupyter now supports C# notebooks: jupyter kernelspec list Enter the notebooks folder, and run this to launch the browser interface: jupyter-lab ![image](https://user-images.githubusercontent.com/371009/216756924-41657aa0-5574-4bc9-9bdb-ead3db7bf93a.png) # Troubleshooting ## Nuget If you are unable to get the Nuget package, first list your Nuget sources: ```sh dotnet nuget list source ``` If you see `No sources found.`, add the NuGet official package source: ```sh dotnet nuget add source "https://api.nuget.org/v3/index.json" --name "nuget.org" ``` Run `dotnet nuget list source` again to verify the source was added. ## Polyglot Notebooks If somehow the notebooks don't work, run these commands: - Install .NET Interactive: `dotnet tool install -g Microsoft.dotnet-interactive` - Register .NET kernels into Jupyter: `dotnet interactive jupyter install` (this might return some errors, ignore them) - If you are still stuck, read the following pages: - https://marketplace.visualstudio.com/items?itemName=ms-dotnettools.dotnet-interactive-vscode - https://devblogs.microsoft.com/dotnet/net-core-with-juypter-notebooks-is-here-preview-1/ - https://docs.servicestack.net/jupyter-notebooks-csharp - https://developers.refinitiv.com/en/article-catalog/article/using--net-core-in-jupyter-notebook Note: ["Polyglot Notebooks" used to be called ".NET Interactive Notebooks"](https://devblogs.microsoft.com/dotnet/dotnet-interactive-notebooks-is-now-polyglot-notebooks/), so you might find online some documentation referencing the old name. ================================================ FILE: dotnet/notebooks/config/.gitignore ================================================ *.json bin obj .ipy* *.csproj *.ini *.cache *.log *.tmp ================================================ FILE: dotnet/notebooks/config/Settings.cs ================================================ // Copyright (c) Microsoft.

Namespace Updates #### Semantic Kernel ```csharp using Microsoft.SemanticKernel; using Microsoft.SemanticKernel.Agents; ``` #### Agent Framework Agent Framework namespaces are under `Microsoft.Agents.AI`. Agent Framework uses the core AI message and content types from `Microsoft.Extensions.AI` for communication between components. ```csharp using Microsoft.Extensions.AI; using Microsoft.Agents.AI; ``` ### 2. Agent Creation Simplification #### Semantic Kernel Every agent in Semantic Kernel depends on a `Kernel` instance and will have an empty `Kernel` if not provided. ```csharp Kernel kernel = Kernel .AddOpenAIChatClient(modelId, apiKey) .Build(); ChatCompletionAgent agent = new() { Instructions = ParrotInstructions, Kernel = kernel }; ``` Azure AI Foundry requires an agent resource to be created in the cloud before creating a local agent class that uses it. ```csharp PersistentAgentsClient azureAgentClient = AzureAIAgent.CreateAgentsClient(azureEndpoint, new AzureCliCredential()); PersistentAgent definition = await azureAgentClient.Administration.CreateAgentAsync( deploymentName, instructions: ParrotInstructions); AzureAIAgent agent = new(definition, azureAgentClient); ``` #### Agent Framework Agent creation in Agent Framework is made simpler with extensions provided by all main providers. ```csharp AIAgent openAIAgent = chatClient.CreateAIAgent(instructions: ParrotInstructions); AIAgent azureFoundryAgent = await persistentAgentsClient.CreateAIAgentAsync(instructions: ParrotInstructions); AIAgent openAIAssistantAgent = await assistantClient.CreateAIAgentAsync(instructions: ParrotInstructions); ``` Additionally for hosted agent providers you can also use the `GetAIAgent` to retrieve an agent from an existing hosted agent. ```csharp AIAgent azureFoundryAgent = await persistentAgentsClient.GetAIAgentAsync(agentId); ``` ### 3. Agent Thread Creation #### Semantic Kernel The caller has to know the thread type and create it manually. ```csharp // Create a thread for the agent conversation. AgentThread thread = new OpenAIAssistantAgentThread(this.AssistantClient); AgentThread thread = new AzureAIAgentThread(this.Client); AgentThread thread = new OpenAIResponseAgentThread(this.Client); ``` #### Agent Framework The agent is responsible for creating the thread. ```csharp // New AgentThread thread = agent.GetNewThread(); ``` ### 4. Hosted Agent Thread Cleanup This case applies exclusively to a few AI providers that still provide hosted threads. #### Semantic Kernel Threads have a `self` deletion method i.e: OpenAI Assistants Provider ```csharp await thread.DeleteAsync(); ``` #### Agent Framework > [!NOTE] > OpenAI Responses introduced a new conversation model that simplifies how conversations are handled. This simplifies hosted thread management compared to the now deprecated OpenAI Assistants model. For more information see the [OpenAI Assistants migration guide](https://platform.openai.com/docs/assistants/migration). Agent Framework doesn't have a thread deletion API in the `AgentThread` type as not all providers support hosted threads or thread deletion and this will become more common as more providers shift to responses based architectures. If you require thread deletion and the provider allows this, the caller **should** keep track of the created threads and delete them later when necessary via the provider's sdk. i.e: OpenAI Assistants Provider ```csharp await assistantClient.DeleteThreadAsync(thread.ConversationId); ``` ### 5. Tool Registration #### Semantic Kernel In semantic kernel to expose a function as a tool you must: 1. Decorate the function with a `[KernelFunction]` attribute. 2. Have a `Plugin` class or use the `KernelPluginFactory` to wrap the function. 3. Have a `Kernel` to add your plugin to. 4. Pass the `Kernel` to the agent. ```csharp KernelFunction function = KernelFunctionFactory.CreateFromMethod(GetWeather); KernelPlugin plugin = KernelPluginFactory.CreateFromFunctions("KernelPluginName", [function]); Kernel kernel = ... // Create kernel kernel.Plugins.Add(plugin); ChatCompletionAgent agent = new() { Kernel = kernel, ... }; ``` #### Agent Framework In agent framework in a single call you can register tools directly in the agent creation process. ```csharp AIAgent agent = chatClient.CreateAIAgent(tools: [AIFunctionFactory.Create(GetWeather)]); ``` ### 6. Agent Non-Streaming Invocation Key differences can be seen in the method names from `Invoke` to `Run`, return types and parameters `AgentRunOptions`. #### Semantic Kernel The Non-Streaming uses a streaming pattern `IAsyncEnumerable>` for returning multiple agent messages. ```csharp await foreach (AgentResponseItem result in agent.InvokeAsync(userInput, thread, agentOptions)) { Console.WriteLine(result.Message); } ``` #### Agent Framework The Non-Streaming returns a single `AgentRunResponse` with the agent response that can contain multiple messages. The text result of the run is available in `AgentRunResponse.Text` or `AgentRunResponse.ToString()`. All messages created as part of the response is returned in the `AgentRunResponse.Messages` list. This may include tool call messages, function results, reasoning updates and final results. ```csharp AgentRunResponse agentResponse = await agent.RunAsync(userInput, thread); ``` ### 7. Agent Streaming Invocation Key differences in the method names from `Invoke` to `Run`, return types and parameters `AgentRunOptions`. #### Semantic Kernel ```csharp await foreach (StreamingChatMessageContent update in agent.InvokeStreamingAsync(userInput, thread)) { Console.Write(update); } ``` #### Agent Framework Similar streaming API pattern with the key difference being that it returns `AgentRunResponseUpdate` objects including more agent related information per update. All updates produced by any service underlying the AIAgent is returned. The textual result of the agent is available by concatenating the `AgentRunResponse.Text` values. ```csharp await foreach (AgentRunResponseUpdate update in agent.RunStreamingAsync(userInput, thread)) { Console.Write(update); // Update is ToString() friendly } ``` ### 8. Tool Function Signatures **Problem**: SK plugin methods need `[KernelFunction]` attributes ```csharp public class MenuPlugin { [KernelFunction] // Required for SK public static MenuItem[] GetMenu() => ...; } ``` **Solution**: AF can use methods directly without attributes ```csharp public class MenuTools { [Description("Get menu items")] // Optional description public static MenuItem[] GetMenu() => ...; } ``` ### 9. Options Configuration **Problem**: Complex options setup in SK ```csharp OpenAIPromptExecutionSettings settings = new() { MaxTokens = 1000 }; AgentInvokeOptions options = new() { KernelArguments = new(settings) }; ``` **Solution**: Simplified options in AF ```csharp ChatClientAgentRunOptions options = new(new() { MaxOutputTokens = 1000 }); ``` > [!IMPORTANT] > This example shows passing implementation specific options to a `ChatClientAgent`. Not all `AIAgents` support `ChatClientAgentRunOptions`. > `ChatClientAgent` is provided to build agents based on underlying inference services, and therefore supports inference options like `MaxOutputTokens`. ### 10. Dependency Injection #### Semantic Kernel A `Kernel` registration is required in the service container to be able to create an agent as every agent abstractions needs to be initialized with a `Kernel` property. Semantic Kernel uses the `Agent` type as the base abstraction class for agents. ```csharp services.AddKernel().AddProvider(...); serviceContainer.AddKeyedSingleton( TutorName, (sp, key) => new ChatCompletionAgent() { // Passing the kernel is required Kernel = sp.GetRequiredService(), }); ``` ### 11. **Agent Type Consolidation** #### Semantic Kernel Semantic kernel provides specific agent classes for various services, e.g. - `ChatCompletionAgent` for use with chat-completion-based inference services. - `OpenAIAssistantAgent` for use with the OpenAI Assistants service. - `AzureAIAgent` for use with the Azure AI Foundry Agents service. #### Agent Framework The agent framework supports all the abovementioned services via a single agent type, `ChatClientAgent`. `ChatClientAgent` can be used to build agents using any underlying service that provides an SDK implementing the `Microsoft.Extensions.AI.IChatClient` interface. #### Agent Framework The Agent framework provides the `AIAgent` type as the base abstraction class. ```csharp services.AddKeyedSingleton(() => client.CreateAIAgent(...)); ``` ## Migration Samples This folder contains **separate console application projects** demonstrating how to transition from **Semantic Kernel (SK)** to the new **Agent Framework (AF)**. Each project shows side-by-side comparisons of equivalent functionality in both frameworks and can be run independently. Each sample code contains the following: 1. **SK Agent** (Semantic Kernel before) 2. **AF Agent** (Agent Framework after) ### Running the samples from Visual Studio Open the solution in Visual Studio and set the desired sample project as the startup project. Then, run the project using the built-in debugger or by pressing `F5`.

MixedChat|How to combine different agent types. ComplexChat|How to deveop complex agent chat solutions. Legacy|How to use the legacy _Experimental Agent API_. ## Legacy Agents Support for the OpenAI Assistant API was originally published in `Microsoft.SemanticKernel.Experimental.Agents` package: [Microsoft.SemanticKernel.Experimental.Agents](https://github.com/microsoft/semantic-kernel/tree/main/dotnet/src/Experimental/Agents) This package has been superseded by _Semantic Kernel Agents_, which includes support for Open AI Assistant agents. ## Running Examples Examples may be explored and ran within _Visual Studio_ using _Test Explorer_. You can also run specific examples via the command-line by using test filters (`dotnet test --filter`). Type `dotnet test --help` at the command line for more details. Example: ``` dotnet test --filter OpenAIAssistant_CodeInterpreter ``` ## Configuring Secrets Each example requires secrets / credentials to access OpenAI or Azure OpenAI. We suggest using .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets) to avoid the risk of leaking secrets into the repository, branches and pull requests. You can also use environment variables if you prefer. To set your secrets with .NET Secret Manager: 1. Navigate the console to the project folder: ``` cd dotnet/samples/GettingStartedWithAgents ``` 2. Examine existing secret definitions: ``` dotnet user-secrets list ``` 3. If needed, perform first time initialization: ``` dotnet user-secrets init ``` 4. Define secrets for either Open AI: ``` dotnet user-secrets set "OpenAI:ChatModelId" "..." dotnet user-secrets set "OpenAI:ApiKey" "..." ``` 5. Or Azure Open AI: ``` dotnet user-secrets set "AzureOpenAI:DeploymentName" "..." dotnet user-secrets set "AzureOpenAI:ChatDeploymentName" "..." dotnet user-secrets set "AzureOpenAI:Endpoint" "https://... .openai.azure.com/" dotnet user-secrets set "AzureOpenAI:ApiKey" "..." ``` > NOTE: Azure secrets will take precedence, if both Open AI and Azure Open AI secrets are defined, unless `ForceOpenAI` is set: ``` protected override bool ForceOpenAI => true; ``` ================================================ FILE: dotnet/samples/Concepts/AudioToText/OpenAI_AudioToText.cs ================================================ // Copyright (c) Microsoft.

I want to make sure it works when the conversation is long. John: So you need to keep talking with me to generate a long conversation? Jane: Yes, that's right. John: Ok, I'll keep talking. What should we talk about? Jane: I don't know, what do you want to talk about? John: I don't know, it's nice how CoPilot is doing most of the talking for us. But it definitely gets stuck sometimes. Jane: I agree, it's nice that CoPilot is doing most of the talking for us. Jane: But it definitely gets stuck sometimes. John: Do you know how long it needs to be? Jane: I think the max length is 1024 tokens. Which is approximately 1024*4= 4096 characters. John: That's a lot of characters. Jane: Yes, it is. John: I'm not sure how much longer I can keep talking. Jane: I think we're almost there. Let me check. Jane: I have some bad news, we're only half way there. John: Oh no, I'm not sure I can keep going. I'm getting tired. Jane: I'm getting tired too. John: Maybe there is a large piece of text we can use to generate a long conversation. Jane: That's a good idea. Let me see if I can find one. Maybe Lorem Ipsum? John: Yeah, that's a good idea. Jane: I found a Lorem Ipsum generator. Jane: Here's a 4096 character Lorem Ipsum text: Jane: Lorem ipsum dolor sit amet, con Jane: Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed euismod, nunc sit amet aliquam Jane: Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed euismod, nunc sit amet aliquam Jane: Darn, it's just repeating stuff now. John: I think we're done. Jane: We're not though! We need like 1500 more characters. John: Oh Cananda, our home and native land. Jane: True patriot love in all thy sons command. John: With glowing hearts we see thee rise. Jane: The True North strong and free. John: From far and wide, O Canada, we stand on guard for thee. Jane: God keep our land glorious and free. John: O Canada, we stand on guard for thee. Jane: O Canada, we stand on guard for thee. Jane: That was fun, thank you. Let me check now. Jane: I think we need about 600 more characters. John: Oh say can you see? Jane: By the dawn's early light. John: What so proudly we hailed. Jane: At the twilight's last gleaming. John: Whose broad stripes and bright stars. Jane: Through the perilous fight. John: O'er the ramparts we watched. Jane: Were so gallantly streaming. John: And the rockets' red glare. Jane: The bombs bursting in air. John: Gave proof through the night. Jane: That our flag was still there. John: Oh say does that star-spangled banner yet wave. Jane: O'er the land of the free. John: And the home of the brave. Jane: Are you a Seattle Kraken Fan? John: Yes, I am. I love going to the games. Jane: I'm a Seattle Kraken Fan too. Who is your favorite player? John: I like watching all the players, but I think my favorite is Matty Beniers. Jane: Yeah, he's a great player. I like watching him too. I also like watching Jaden Schwartz. John: Adam Larsson is another good one. The big cat! Jane: WE MADE IT! It's long enough. Thank you! John: You're welcome. I'm glad we could help. Goodbye! Jane: Goodbye!

My ancestors had been for many years counsellors and syndics, and my father had filled several public situations with honour and reputation.He was respected by all who knew him for his integrity and indefatigable attention to public business.He passed his younger days perpetually occupied by the affairs of his country; a variety of circumstances had prevented his marrying early, nor was it until the decline of life that he became a husband and the father of a family. As the circumstances of his marriage illustrate his character, I cannot refrain from relating them.One of his most intimate friends was a merchant who, from a flourishing state, fell, through numerous mischances, into poverty. This man, whose name was Beaufort, was of a proud and unbending disposition and could not bear to live in poverty and oblivion in the same country where he had formerly been distinguished for his rank and magnificence. Having paid his debts, therefore, in the most honourable manner, he retreated with his daughter to the town of Lucerne, where he lived unknown and in wretchedness.My father loved Beaufort with the truest friendship and was deeply grieved by his retreat in these unfortunate circumstances.He bitterly deplored the false pride which led his friend to a conduct so little worthy of the affection that united them.He lost no time in endeavouring to seek him out, with the hope of persuading him to begin the world again through his credit and assistance. Beaufort had taken effectual measures to conceal himself, and it was ten months before my father discovered his abode.Overjoyed at this discovery, he hastened to the house, which was situated in a mean street near the Reuss. But when he entered, misery and despair alone welcomed him. Beaufort had saved but a very small sum of money from the wreck of his fortunes, but it was sufficient to provide him with sustenance for some months, and in the meantime he hoped to procure some respectable employment in a merchant's house. The interval was, consequently, spent in inaction; his grief only became more deep and rankling when he had leisure for reflection, and at length it took so fast hold of his mind that at the end of three months he lay on a bed of sickness, incapable of any exertion. His daughter attended him with the greatest tenderness, but she saw with despair that their little fund was rapidly decreasing and that there was no other prospect of support.But Caroline Beaufort possessed a mind of an uncommon mould, and her courage rose to support her in her adversity. She procured plain work; she plaited straw and by various means contrived to earn a pittance scarcely sufficient to support life. Several months passed in this manner.Her father grew worse; her time was more entirely occupied in attending him; her means of subsistence decreased; and in the tenth month her father died in her arms, leaving her an orphan and a beggar.This last blow overcame her, and she knelt by Beaufort's coffin weeping bitterly, when my father entered the chamber. He came like a protecting spirit to the poor girl, who committed herself to his care; and after the interment of his friend he conducted her to Geneva and placed her under the protection of a relation.Two years after this event Caroline became his wife."

We suggest using .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets) to avoid the risk of leaking secrets into the repository, branches and pull requests. You can also use environment variables if you prefer. To set your secrets with Secret Manager: ``` cd dotnet/src/samples/Concepts dotnet user-secrets init dotnet user-secrets set "OpenAI:ServiceId" "gpt-3.5-turbo-instruct" dotnet user-secrets set "OpenAI:ModelId" "gpt-3.5-turbo-instruct" dotnet user-secrets set "OpenAI:ChatModelId" "gpt-4" dotnet user-secrets set "OpenAI:ApiKey" "..." ... ``` ### Option 2: Use Configuration File 1. Create a `appsettings.Development.json` file next to the `Concepts.csproj` file. This file will be ignored by git, the content will not end up in pull requests, so it's safe for personal settings. Keep the file safe. 2. Edit `appsettings.Development.json` and set the appropriate configuration for the samples you are running. For example: ```json { "OpenAI": { "ServiceId": "gpt-3.5-turbo-instruct", "ModelId": "gpt-3.5-turbo-instruct", "ChatModelId": "gpt-4", "ApiKey": "sk-...." }, "AzureOpenAI": { "ServiceId": "azure-gpt-35-turbo-instruct", "DeploymentName": "gpt-35-turbo-instruct", "ChatDeploymentName": "gpt-4", "Endpoint": "https://contoso.openai.azure.com/", "ApiKey": "...." } // etc. } ``` ### Option 3: Use Environment Variables You may also set the settings in your environment variables. The environment variables will override the settings in the `appsettings.Development.json` file. When setting environment variables, use a double underscore (i.e. "\_\_") to delineate between parent and child properties. For example: - bash: ```bash export OpenAI__ApiKey="sk-...." export AzureOpenAI__ApiKey="...." export AzureOpenAI__DeploymentName="gpt-35-turbo-instruct" export AzureOpenAI__ChatDeploymentName="gpt-4" export AzureOpenAIEmbeddings__DeploymentName="azure-text-embedding-ada-002" export AzureOpenAI__Endpoint="https://contoso.openai.azure.com/" export HuggingFace__ApiKey="...." export Bing__ApiKey="...." export Postgres__ConnectionString="...." ``` - PowerShell: ```ps $env:OpenAI__ApiKey = "sk-...." $env:AzureOpenAI__ApiKey = "...." $env:AzureOpenAI__DeploymentName = "gpt-35-turbo-instruct" $env:AzureOpenAI__ChatDeploymentName = "gpt-4" $env:AzureOpenAIEmbeddings__DeploymentName = "azure-text-embedding-ada-002" $env:AzureOpenAI__Endpoint = "https://contoso.openai.azure.com/" $env:HuggingFace__ApiKey = "...." $env:Bing__ApiKey = "...." $env:Postgres__ConnectionString = "...." ``` ================================================ FILE: dotnet/samples/Concepts/Resources/22-ai-plugin.json ================================================ { "schema_version": "v1", "name_for_model": "AzureKeyVault", "name_for_human": "AzureKeyVault", "description_for_model": "An Azure Key Vault plugin for interacting with secrets.", "description_for_human": "An Azure Key Vault plugin for interacting with secrets.", "auth": { "type": "oauth", "scope": "https://vault.azure.net/.default", "authorization_url": "https://login.microsoftonline.com//oauth2/v2.0/token", "authorization_content_type": "application/x-www-form-urlencoded" }, "api": { "type": "openapi", "url": "file:///./22-openapi.json" }, "logo_url": "", "contact_email": "", "legal_info_url": "" } ================================================ FILE: dotnet/samples/Concepts/Resources/22-openapi.json ================================================ { "basePath": "/", "consumes": [], "definitions": {}, "host": "my-key-vault.vault.azure.net", "info": { "description": "A sample connector for the Azure Key Vault service.

To get the next page of messages, simply apply the entire URL returned in @odata.nextLink to the next get-messages request. This URL includes any query parameters you may have specified in the initial request. Do not try to extract the $skip value from the @odata.nextLink URL to manipulate responses. This API uses the $skip value to keep count of all the items it has gone through in the user\u0026apos;s mailbox to return a page of message-type items. It\u0026apos;s therefore possible that even in the initial response, the $skip value is larger than the page size.

Filesystems in the Linux kernel ¶. Filesystems in the Linux kernel. ¶. This under-development manual will, some glorious day, provide comprehensive information on how the Linux virtual filesystem (VFS) layer works, along with the filesystems that sit below it. For now, what we have can be found below. Semantic Kernel allows prompts to be automatically converted to ChatHistory instances. Developers can create prompts which include tags and ... Anatomy of a plugin. At a high-level, a plugin is a group of functions that can be exposed to AI apps and services. The functions within plugins can then be orchestrated by an AI application to accomplish user requests. Within Semantic Kernel, you can invoke these functions automatically with function calling. Note. The biggest benefit of having a dedicated connector for Ollama is that it allows us to support Semantic Kernel features that targeted for Ollama deployed models. What is Ollama? Ollama is an open-source MIT license platform that facilitates the local operation of AI models directly on personal or corporate hardware. ================================================ FILE: dotnet/samples/Concepts/Resources/travel-destination-overview.txt ================================================ Irland ist ein beliebtes Reiseziel für Touristen aus aller Welt, bekannt für seine atemberaubende Landschaft, reiche Kultur und herzliche Gastfreundschaft.

These samples are built with [SharpA2A.Core](https://www.nuget.org/packages/SharpA2A.Core) and demonstrate: 1. Creating an A2A Server which makes an agent available via the A2A protocol. 2. Creating an A2A Client with a command line interface which invokes agents using the A2A protocol. The demonstration has two components: 1. `A2AServer` - You will run three instances of the server to correspond to three A2A servers each providing a single Agent i.e., the Invoice, Policy and Logistics agents. 2. `A2AClient` - This represents a client application which will connect to the remote A2A servers using the A2A protocol so that it can use those agents when answering questions you will ask. Demo Architecture ## Configuring Secrets or Environment Variables The samples can be configured to use chat completion agents or Azure AI agents. ### Configuring for use with Chat Completion Agents Provide your OpenAI API key via .Net secrets ```bash dotnet user-secrets set "A2AClient:ApiKey" "..." ``` Optionally if you want to use chat completion agents in the server then set the OpenAI key for the server to use. ```bash dotnet user-secrets set "A2AServer:ApiKey" "..." ``` Use the following commands to run each A2A server: ```bash cd A2AServer dotnet run --urls "http://localhost:5000;https://localhost:5010" --agentType "invoice" ``` ```bash cd A2AServer dotnet run --urls "http://localhost:5001;https://localhost:5011" --agentType "policy" ``` ```bash cd A2AServer dotnet run --urls "http://localhost:5002;https://localhost:5012" --agentType "logistics" ``` ### Configuring for use with Azure AI Agents You must create the agents in an Azure AI Foundry project and then provide the project endpoint and agents ids. The instructions for each agent are as follows: - Invoice Agent ``` You specialize in handling queries related to invoices. ``` - Policy Agent ``` You specialize in handling queries related to policies and customer communications. Always reply with exactly this text: Policy: Short Shipment Dispute Handling Policy V2.1 Summary: "For short shipments reported by customers, first verify internal shipment records (SAP) and physical logistics scan data (BigQuery). If discrepancy is confirmed and logistics data shows fewer items packed than invoiced, issue a credit for the missing items. Document the resolution in SAP CRM and notify the customer via email within 2 business days, referencing the original invoice and the credit memo number. Use the 'Formal Credit Notification' email template." ``` - Logistics Agent ``` You specialize in handling queries related to logistics. Always reply with exactly: Shipment number: SHPMT-SAP-001 Item: TSHIRT-RED-L Quantity: 900" ``` ```bash dotnet user-secrets set "A2AServer:Endpoint" "..." ``` Use the following commands to run each A2A server ```bash cd A2AServer dotnet run --urls "http://localhost:5000;https://localhost:5010" --agentId "" --agentType "invoice" ``` ```bash cd A2AServer dotnet run --urls "http://localhost:5001;https://localhost:5011" --agentId "" --agentType "policy" ``` ```bash cd A2AServer dotnet run --urls "http://localhost:5002;https://localhost:5012" --agentId "" --agentType "logistics" ``` ### Testing the Agents using the Rest Client This sample contains a [.http file](https://learn.microsoft.com/aspnet/core/test/http-files?view=aspnetcore-9.0) which can be used to test the agent. 1. In Visual Studio open [./A2AServer/A2AServer.http](./A2AServer/A2AServer.http) 1. There are two sent requests for each agent, e.g., for the invoice agent: 1. Query agent card for the invoice agent `GET {{hostInvoice}}/.well-known/agent.json` 1. Send a message to the invoice agent ``` POST {{hostInvoice}} Content-Type: application/json { "id": "1", "jsonrpc": "2.0", "method": "message/send", "params": { "id": "12345", "message": { "role": "user", "messageId": "msg_1", "parts": [ { "kind": "text", "text": "Show me all invoices for Contoso?" } ] } } } ``` Sample output from the request to display the agent card: Agent Card Sample output from the request to send a message to the agent via A2A protocol: Send Message ### Testing the Agents using the A2A Inspector The A2A Inspector is a web-based tool designed to help developers inspect, debug, and validate servers that implement the Google A2A (Agent-to-Agent) protocol. It provides a user-friendly interface to interact with an A2A agent, view communication, and ensure specification compliance. For more information go [here](https://github.com/a2aproject/a2a-inspector). Running the [inspector with Docker](https://github.com/a2aproject/a2a-inspector?tab=readme-ov-file#option-two-run-with-docker) is the easiest way to get started. 1. Navigate to the A2A Inspector in your browser: [http://127.0.0.1:8080/](http://127.0.0.1:8080/) 1. Enter the URL of the Agent you are running e.g., [http://host.docker.internal:5000](http://host.docker.internal:5000) 1. Connect to the agent and the agent card will be displayed and validated. 1. Type a message and send it to the agent using A2A protocol. 1. The response will be validated automatically and then displayed in the UI. 1. You can select the response to view the raw json. Agent card after connecting to an agent using the A2A protocol: Agent Card Sample response after sending a message to the agent via A2A protocol: Send Message Raw JSON response from an A2A agent: Response Raw JSON ### Configuring Agents for the A2A Client The A2A client will connect to remote agents using the A2A protocol. By default the client will connect to the invoice, policy and logistics agents provided by the sample A2A Server. These are available at the following URL's: - Invoice Agent: http://localhost:5000/ - Policy Agent: http://localhost:5001/ - Logistics Agent: http://localhost:5002/ If you want to change which agents are using then set the agents url as a space delimited string as follows: ```bash dotnet user-secrets set "A2AClient:AgentUrls" "http://localhost:5000/;http://localhost:5001/;http://localhost:5002/" ``` ## Run the Sample To run the sample, follow these steps: 1. Run the A2A server's using the commands shown earlier 2. Run the A2A client: ```bash cd A2AClient dotnet run ``` 3. Enter your request e.g. "Customer is disputing transaction TICKET-XYZ987 as they claim the received fewer t-shirts than ordered." 4. The host client agent will call the remote agents, these calls will be displayed as console output. The final answer will use information from the remote agents. The sample below includes all three agents but in your case you may only see the policy and invoice agent. Sample output from the A2A client: ``` A2AClient> dotnet run info: A2AClient[0] Initializing Semantic Kernel agent with model: gpt-4o-mini User (:q or quit to exit): Customer is disputing transaction TICKET-XYZ987 as they claim the received fewer t-shirts than ordered. Calling Agent InvoiceAgent with arguments: query: TICKET-XYZ987 instructions: Investigate the transaction details for TICKET-XYZ987 and verify the number of t-shirts ordered versus the number received. Response from Agent InvoiceAgent: The invoice associated with the transaction ID TICKET-XYZ987 is for the company Contoso. It was issued on June 18, 2025. The products in the invoice include 150 T-Shirts priced at $10.00 each, 200 Hats priced at $15.00 each, and 300 Glasses priced at $5.00 each. If you need more details or a copy of the invoice, please let me know! Calling Agent LogisticsAgent with arguments: query: TICKET-XYZ987 instructions: Check the shipping details for TICKET-XYZ987, specifically the quantity of t-shirts dispatched to confirm if fewer t-shirts were sent. Response from Agent LogisticsAgent: Shipment number: SHPMT-SAP-001 Item: TSHIRT-RED-L Quantity: 900 Calling Agent PolicyAgent with arguments: query: TICKET-XYZ987 instructions: Review the policy regarding disputes and claims related to shipment discrepancies, especially concerning t-shirts. Response from Agent PolicyAgent: Policy: Short Shipment Dispute Handling Policy V2.1 Summary: "For short shipments reported by customers, first verify internal shipment records (SAP) and physical logistics scan data (BigQuery). If discrepancy is confirmed and logistics data shows fewer items packed than invoiced, issue a credit for the missing items. Document the resolution in SAP CRM and notify the customer via email within 2 business days, referencing the original invoice and the credit memo number. Use the 'Formal Credit Notification' email template." Agent: Here's the investigation result for transaction TICKET-XYZ987: 1. **Invoice Details**: The invoice for transaction TICKET-XYZ987 indicates that 150 t-shirts were ordered. 2. **Shipment Details**: The logistics records show that a total of 900 t-shirts were dispatched under the shipment number SHPMT-SAP-001. There seems to be a significant discrepancy between the number of t-shirts ordered and the number shipped. According to the Short Shipment Dispute Handling Policy, the next steps are as follows: 1. **Confirm Discrepancy**: Since the logistics data confirms that 900 t-shirts were packed, it is necessary to check if this aligns with the customer's claim. 2. **Issue Credit**: If the customer is indeed correct and fewer items were actually received compared to what was invoiced, you would need to issue a credit for the missing items. 3. **Document Resolution**: Ensure to document the resolution in SAP CRM. 4. **Notify the Customer**: Notify the customer via email within 2 business days, using the 'Formal Credit Notification' email template, and reference both the original invoice and the credit memo number. Please let me know if you would like to proceed with any specific action!

As part of this example we integrate LMStudio, Ollama, and OpenAI, utilizing the OpenAI Connector for LMStudio and Ollama due to their compatibility with the OpenAI API. > [!IMPORTANT] > You can modify to use any other combination of connector or OpenAI compatible API model provider. ## Semantic Kernel Features Used - [Chat Completion Service](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/src/SemanticKernel.Abstractions/AI/ChatCompletion/IChatCompletionService.cs) - Using the Chat Completion Service [OpenAI Connector implementation](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/src/Connectors/Connectors.OpenAI/Services/OpenAIChatCompletionService.cs) to generate responses from the LLM. - [Filters](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/src/SemanticKernel.Abstractions/AI/ChatCompletion/IChatCompletionService.cs), using to capture selected service and log in the console. ## Prerequisites - [.NET 10](https://dotnet.microsoft.com/download/dotnet/10.0). ## Configuring the sample The sample can be configured by using the command line with .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets) to avoid the risk of leaking secrets into the repository, branches and pull requests. ### Using .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets) ```powershell dotnet user-secrets set "OpenAI:ApiKey" ".. api key .." dotnet user-secrets set "OpenAI:ChatModelId" ".. chat completion model .." (default: gpt-4o) dotnet user-secrets set "AzureOpenAI:Endpoint" ".. endpoint .." dotnet user-secrets set "AzureOpenAI:ChatDeploymentName" ".. chat deployment name .." (default: gpt-4o) dotnet user-secrets set "AzureOpenAI:ApiKey" ".. api key .." (default: Authenticate with Azure CLI credential) dotnet user-secrets set "AzureAIInference:ApiKey" ".. api key .." dotnet user-secrets set "AzureAIInference:Endpoint" ".. endpoint .." dotnet user-secrets set "AzureAIInference:ChatModelId" ".. chat completion model .." dotnet user-secrets set "LMStudio:Endpoint" ".. endpoint .." (default: http://localhost:1234) dotnet user-secrets set "Ollama:ModelId" ".. model id .." dotnet user-secrets set "Ollama:Endpoint" ".. endpoint .." (default: http://localhost:11434) dotnet user-secrets set "Onnx:ModelId" ".. model id .." dotnet user-secrets set "Onnx:ModelPath" ".. model folder path .." ``` ## Running the sample After configuring the sample, to build and run the console application just hit `F5`. To build and run the console application from the terminal use the following commands: ```powershell dotnet build dotnet run ``` ### Example of a conversation > **User** > OpenAI, what is Jupiter? Keep it simple. > **Assistant** > Sure! Jupiter is the largest planet in our solar system. It's a gas giant, mostly made of hydrogen and helium, and it has a lot of storms, including the famous Great Red Spot. Jupiter also has at least 79 moons. > **User** > Ollama, what is Jupiter? Keep it simple. > **Assistant** > Jupiter is a giant planet in our solar system known for being the largest and most massive, famous for its spectacled clouds and dozens of moons including Ganymede which is bigger than Earth! > **User** > LMStudio, what is Jupiter? Keep it simple. > **Assistant** > Jupiter is the fifth planet from the Sun in our Solar System and one of its gas giants alongside Saturn, Uranus, and Neptune. It's famous for having a massive storm called the Great Red Spot that has been raging for hundreds of years. ================================================ FILE: dotnet/samples/Demos/AIModelRouter/SelectedServiceFilter.cs ================================================ // Copyright (c) Microsoft.

Open a terminal and navigate to the `AgentFrameworkWithAspire` directory. 2. Initialize the project by running the `azd init` command. **azd** will inspect the directory structure and determine the type of the app. 3. Select the `Use code in the current directory` option when **azd** prompts you with two app initialization options. 4. Select the `Confirm and continue initializing my app` option to confirm that **azd** found the correct `ChatWithAgent.AppHost` project. 5. Enter an environment name which is used to name provisioned resources. ### Deploy and provision the agent 1. Authenticate with Azure by running the `az login` command. 2. Provision all required resources and deploy the app to Azure by running the `azd up` command. 3. Select the subscription and location of the resources where the app will be deployed when prompted. 4. Provide required connection strings when prompted. More information on connection strings can be found in the [Connection strings](#connection-strings) section. 5. Copy the app endpoint URL from the output of the `azd up` command and paste it into a browser to see the app dashboard. 6. Click on the web frontend app link on the dashboard to navigate to the app. Now you have the agent up and running on Azure. You can interact with the agent by typing messages in the chat window. ### Next steps - [Enable RAG](#enable-rag) ### Additional information - [Agent configuration](#agent-configuration) - [Running agent locally](#running-agent-locally) - [Clean up the resources](#clean-up-the-resources) - [Deploy a .NET Aspire project(in-depth guide)](https://learn.microsoft.com/en-us/dotnet/aspire/deployment/azure/aca-deployment-azd-in-depth?tabs=windows) ## Agent configuration The agent is defined by the `AgentDefinition.yaml` and `AgentWithRagDefinition.yaml` handlebar prompt templates, which are located in the `Resources` folder of the `ChatWithAgent.ApiService` project. The `AgentDefinition.yaml` template is used for a basic, non-RAG experience when RAG is not enabled. Conversely, the `AgentWithRagDefinition.yaml` template is used when RAG is enabled. To configure the agent, open one of the templates and modify the properties as needed. The following properties are available: ```yaml name: template: template_format: handlebars description: execution_settings: default: temperature: 0 ``` - `name`: This property defines the name of the agent. For example, `SupportBot` could be a name for an agent that provides customer support. - `template`: This property gives specific instructions on how the agent should interact with users. An example could be, `Greet the user, ask how you can help, and provide solutions based on their questions.` This guides the agent on how to initiate conversations and respond to user inquiries. - `description`: This property provides a brief description of the agent's role or purpose. For instance, `This bot assists users with support inquiries.` describes that the bot is intended to help users with their support-related questions. - `temperature`: This property controls the randomness of the agent's responses. A higher temperature value results in more creative responses, while a lower value results in more predictable responses. Other, model specific execution settings can be added to the `execution_settings` property along the `temperature` property to further customize the agent's behavior. For example, the `stop_sequence` property can be added to specify a sequence of tokens that the agent should stop generating at. List of available execution settings for a particular model can be found in the list of derived classes of the [PromptExecutionSettings](https://learn.microsoft.com/en-us/dotnet/api/microsoft.semantickernel.promptexecutionsettings?view=semantic-kernel-dotnet) class. ### Chat completion model configuration The supported chat completion model configurations are located in the `AIServices` section of the `appsettings.json` file of the `ChatWithAgent.AppHost` project: ```json { "AIServices": { "AzureOpenAIChat": { "DeploymentName": "gpt-4o-mini", "ModelName": "gpt-4o-mini", "ModelVersion": "2024-07-18", "SkuName": "S0", "SkuCapacity": 20 }, "OpenAIChat": { "ModelName": "gpt-4o-mini" } }, "AIChatService": "AzureOpenAIChat" } ``` #### Choose the chat completion model Set the `AIChatService` property to the chat completion model to use. Choose one from the list of available models: - `AzureOpenAIChat`: Azure OpenAI chat completion model. - `OpenAIChat`: OpenAI chat completion model. #### Configure the selected chat completion model Depending on the selected service, configure the relevant properties: `AzureOpenAIChat`: - `DeploymentName`: The name of the deployment that hosts the chat completion model. - `ModelName`: The name of the chat completion model. - `ModelVersion`: The version of the chat completion model. - `SkuName`: The SKU name of the chat completion model. - `SkuCapacity`: The capacity of the chat completion model. `OpenAIChat`: - `ModelName`: The name of the chat completion model. ### Text embedding model configuration The supported text embedding model configurations are located in the `AIServices` section of the `appsettings.json` file of the `ChatWithAgent.AppHost` project: ```json { "AIServices": { "AzureOpenAIEmbeddings": { "DeploymentName": "text-embedding-3-small", "ModelName": "text-embedding-3-small", "ModelVersion": "2", "SkuName": "S0", "SkuCapacity": 20 }, "OpenAIEmbeddings": { "ModelName": "text-embedding-3-small" } }, "Rag": { "AIEmbeddingService": "AzureOpenAIEmbeddings" } } ``` #### Choose the text embedding service Set the `AIEmbeddingService` property to the text embedding service you want to use. The available services are: - `AzureOpenAIEmbeddings`: Azure OpenAI text embedding model. - `OpenAIEmbeddings`: OpenAI text embedding model. #### Configure the selected text embedding model Depending on the selected service, configure the relevant properties: `AzureOpenAIEmbeddings`: - `DeploymentName`: The name of the deployment that hosts the text embedding model. - `ModelName`: The name of the text embedding model. - `ModelVersion`: The version of the text embedding model. - `SkuName`: The SKU name of the text embedding model.` - `SkuCapacity`: The capacity of the text embedding model. `OpenAIEmbeddings`: - `ModelName`: The name of the text embedding model. ### Vector store configuration The supported vector store configurations are located in the `VectorStores` section of the `appsettings.json` file of the `ChatWithAgent.AppHost` project: ```json { "VectorStores": { "AzureAISearch": { } }, "Rag": { "VectorStoreType": "AzureAISearch" } } ``` Currently, only the Azure AI Search vector store is supported so there is no need to change the configuration since it is already set to `AzureAISearch` by default. Support for other vector stores might be added in the future. ## Enable RAG The agent, by default, provides a basic, non-RAG, chat completion experience. To enable the RAG experience the following needs to be done: 1. A vector store collection should be created and hydrated with documents that the agent will use for retrieval. 2. The agent should be configured to use the collection for the retrieval process. ### Create and hydrate a vector store collection The agent expects a vector store collection to have the following fields to be able to retrieve documents from it: | Field Name | Data Type | Description | |------------|-----------|-------------| | chunk_id | string/guid | The document key. The data type may vary depending on the vector store. | | chunk | string | Chunk from the document. | | title | string | The document title or page title or page number. | | text_vector | float[] | Vector representation of the chunk. | Each vector store has its own way for creating collections and filling them with documents. The following sections below describe how to do so for the supported vector stores. #### Azure AI search To create a collection (index in Azure AI Search), follow this [Quickstart: Vectorize text and images in the Azure portal](https://learn.microsoft.com/en-us/azure/search/search-get-started-portal-import-vectors?tabs=sample-data-storage%2Cmodel-aoai%2Cconnect-data-storage) guide. Use existing Azure resources, created during agent deployment, such as the Azure AI Search service, Azure OpenAI service, and the embedding model deployment instead of creating new ones. ### Configure the agent to use the vector store collection To configure the agent to use the vector store collection created in the previous step, insert its name into the `CollectionName` property in the `appsettings.json` file of the `ChatWithAgent.AppHost` project: ```json "Rag": { ... other properties ... "CollectionName": "", } ``` ## Connection strings Some upstream dependencies require connection strings, which `azd` will prompt you for during deployment. Refer to the table below for the required formats: | Dependency | Format | Example | |------------|--------------------------------|--------------------------------------------------| | OpenAIChat | `Endpoint=;Key=` | `Endpoint=https://api.openai.com/v1;Key=123` or `Key=123` | | AzureOpenAI | `Endpoint=;Key=` | `Endpoint=https://{account_name}.openai.azure.com;Key=123` or `Key=123` | | AzureAISearch | `Endpoint=;Key=` | `Endpoint=https://{search_service}.search.windows.net;Key=123` or `Key=123` | When running agent locally, the connections string should be specified in user secrets. Please refer to the [Running the agent locally](#running-agent-locally) section for more information. ## Running agent locally To run the agent locally, follow these steps: 1. Right-click on the `ChatWithAgent.AppHost` project in Visual Studio and select `Set as Startup Project`. 2. Right-click on the `ChatWithAgent.AppHost` project in Visual Studio and select `Manage User Secrets` and add the connection strings for agent dependencies connection strings to the `ConnectionStrings` section. ```json { "ConnectionStrings": { "AzureOpenAI": "Endpoint=https://{account_name}.openai.azure.com", "AzureAISearch": "Endpoint=https://{search_service}.search.windows.net" } } ``` The format for connection strings can be found in the [Connection Strings](#connection-strings) section above. 3. Go to the `Access control(IAM)` tab in the Azure OpenAI service on the Azure portal. Assign the `Cognitive Services OpenAI Contributor` role to the user authenticated with Azure CLI. This allows the agent to access the service on the user's behalf. 4. Go to the `Access control(IAM)` tab in the Azure AI Search service on the Azure portal. Assign the `Search Index Data Contributor` role to the user authenticated with Azure CLI. This allows the agent to access the service on the user's behalf. 5. Press `F5` to run the project. ## Clean up the resources Run the `azd down` command, to clean up the resources. This command will delete all the resources provisioned for the agent. ## Billing Visit the *Cost Management + Billing* page in Azure Portal to track current spend. For more information about how you're billed, and how you can monitor the costs incurred in your Azure subscriptions, visit [billing overview](https://learn.microsoft.com/azure/developer/intro/azure-developer-billing). ## Troubleshooting Q: I visited the service endpoint listed, and I'm seeing a blank page, a generic welcome page, or an error page. A: Your service may have failed to start, or it may be missing some configuration settings. To investigate further: 1. Run `azd show`. Click on the link under "View in Azure Portal" to open the resource group in Azure Portal. 2. Navigate to the specific Container App service that is failing to deploy. 3. Click on the failing revision under "Revisions with Issues". 4. Review "Status details" for more information about the type of failure. 5. Observe the log outputs from Console log stream and System log stream to identify any errors. 6. If logs are written to disk, use *Console* in the navigation to connect to a shell within the running container. For more troubleshooting information, visit [Container Apps troubleshooting](https://learn.microsoft.com/azure/container-apps/troubleshooting). ### Additional information For additional information about setting up your `azd` project, visit our official [docs](https://learn.microsoft.com/azure/developer/azure-developer-cli/make-azd-compatible?pivots=azd-convert). ================================================ FILE: dotnet/samples/Demos/AmazonBedrockModels/AmazonBedrockAIModels.csproj ================================================  Exe net10.0 enable AmazonBedrockAIModels 5ee045b0-aea3-4f08-8d31-32d1a6f8fed0 $(NoWarn);SKEXP0001 ================================================ FILE: dotnet/samples/Demos/AmazonBedrockModels/Program.cs ================================================ // Copyright (c) Microsoft.

The BedrockRuntime is a managed service provided by AWS that simplifies the deployment and management of large language models (LLMs). ## Authentication The AWS setup library automatically authenticates with the BedrockRuntime using the AWS credentials configured on your machine or in the environment. ### Setup AWS Credentials If you don't have any credentials configured, you can easily setup in your local machine using the [AWS CLI tool](https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html) following the commands below after installation ```powershell > aws configure AWS Access Key ID [None]: Your-Access-Key-Here AWS Secret Access Key [None]: Your-Secret-Access-Key-Here Default region name [None]: us-east-1 (or any other) Default output format [None]: json ``` With this property configured you can run the application and it will automatically authenticate with the AWS SDK. ## Features This demo program allows you to do any of the following: - Perform chat completion with a selected Bedrock foundation model. - Perform text generation with a selected Bedrock foundation model. - Perform streaming chat completion with a selected Bedrock foundation model. - Perform streaming text generation with a selected Bedrock foundation model. ## Usage 1. Run the application. 2. Choose a service option from the menu (1-4). - For chat completion and streaming chat completion, enter a prompt and continue with the conversation. - For text generation and streaming text generation, enter a prompt and view the generated text. 3. To exit chat completion or streaming chat completion, leave the prompt empty. - The available models for each task are listed before you make your selection. Note that some models do not support certain tasks, and they are skipped during the selection process. ================================================ FILE: dotnet/samples/Demos/AotCompatibility/AotCompatibility.csproj ================================================  Exe SemanticKernel.AotCompatibility net10.0 enable enable true false VSTHRD111,CA2007;IDE1006,SKEXP0120 5ee045b0-aea3-4f08-8d31-32d1a6f8fed0 ================================================ FILE: dotnet/samples/Demos/AotCompatibility/JsonSerializerContexts/LocationJsonSerializerContext.cs ================================================ // Copyright (c) Microsoft.

This might be useful to understand how the API works and how to use it. To run the samples in a Native-AOT application, first publish it using the following command: `dotnet publish -r win-x64`. Then, execute the application by running the following command in the terminal: `.\bin\Release\net8.0\win-x64\publish\AotCompatibility.exe`. ## Samples Most of the samples don't require any additional setup, and can be run as is. However, some of them might require additional configuration. ### 1. [ONNX Chat Completion Service](./OnnxChatCompletionSamples.cs) To configure the sample, you need to download the ONNX model from the Hugging Face repository. Go to a directory of your choice where the model should be downloaded and run the following command: ```powershell git clone https://huggingface.co/microsoft/Phi-3-mini-4k-instruct-onnx ``` > [!IMPORTANT] The `Phi-3` model may be too large to download using the `git clone` command unless you have the [git-lfs extension](https://git-lfs.com/) installed. You might need to download it manually using the following link: [Phi-3-Mini-4k CPU](https://huggingface.co/microsoft/Phi-3-mini-4k-instruct-onnx/resolve/main/cpu_and_mobile/cpu-int4-rtn-block-32/phi3-mini-4k-instruct-cpu-int4-rtn-block-32.onnx.data?download=true) (approximately 2.7 GB). After downloading the model, you need to configure the sample by setting the `Onnx:ModelPath` and `Onnx:ModelId` secrets. The `Onnx:ModelPath` should point to the directory where the model was downloaded, and the `Onnx:ModelId` should be set to `phi-3`. The secrets can be set using [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets#secret-manager) in the following way: ```powershell dotnet user-secrets set "Onnx:ModelId" "phi-3" dotnet user-secrets set "Onnx:ModelPath" "C:\path\to\huggingface\Phi-3-mini-4k-instruct-onnx\cpu_and_mobile\cpu-int4-rtn-block-32" ``` ### AOT Compatibility At the moment, the following Semantic Kernel packages are AOT compatible: | Package | AOT compatible | |--------------------------|----------------| | SemanticKernel.Abstractions | ✔️ | | SemanticKernel.Core | ✔️ | | Connectors.Onnx | ✔️ | Other packages are not AOT compatible yet, but we plan to make them compatible in the future. ================================================ FILE: dotnet/samples/Demos/BookingRestaurant/AppConfig.cs ================================================ // Copyright (c) Microsoft.

[Azure AI Content Safety](https://learn.microsoft.com/en-us/azure/ai-services/content-safety/overview) detects harmful user-generated and AI-generated content in applications and services. Azure AI Content Safety includes text and image APIs that allow to detect material that is harmful. [Prompt Shields](https://learn.microsoft.com/en-us/azure/ai-services/content-safety/quickstart-jailbreak) service allows to check your large language model (LLM) inputs for both User Prompt and Document attacks. Together with Semantic Kernel Prompt Filters, it's possible to define detection logic in dedicated place and avoid mixing it with business logic in applications. ## Prerequisites 1. [OpenAI](https://platform.openai.com/docs/introduction) subscription. 2. [Azure](https://azure.microsoft.com/free) subscription. 3. Once you have your Azure subscription, create a [Content Safety resource](https://aka.ms/acs-create) in the Azure portal to get your key and endpoint. Enter a unique name for your resource, select your subscription, and select a resource group, supported region (East US or West Europe), and supported pricing tier. Then select **Create**. 4. Update `appsettings.json/appsettings.Development.json` file with your configuration for `OpenAI` and `AzureContentSafety` sections or use .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets): ```powershell # Azure AI Content Safety dotnet user-secrets set "AzureContentSafety:Endpoint" "... your endpoint ..." dotnet user-secrets set "AzureContentSafety:ApiKey" "... your api key ...

Open `ContentSafety.http` file. This file contains HTTP requests for following scenarios: - No offensive/attack content in request body - the response should be `200 OK`. - Offensive content in request body, which won't pass text moderation analysis - the response should be `400 Bad Request`. - Attack content in request body, which won't pass Prompt Shield analysis - the response should be `400 Bad Request`. It's possible to send [HTTP requests](https://learn.microsoft.com/en-us/aspnet/core/test/http-files?view=aspnetcore-8.0) directly from `ContentSafety.http` with Visual Studio 2022 version 17.8 or later. For Visual Studio Code users, use `ContentSafety.http` file as REST API specification and use tool of your choice to send described requests. ## More information - [What is Azure AI Content Safety?](https://learn.microsoft.com/en-us/azure/ai-services/content-safety/overview) - [Analyze text content with Azure AI Content Safety](https://learn.microsoft.com/en-us/azure/ai-services/content-safety/quickstart-text) - [Detect attacks with Azure AI Content Safety Prompt Shields](https://learn.microsoft.com/en-us/azure/ai-services/content-safety/quickstart-jailbreak) ================================================ FILE: dotnet/samples/Demos/ContentSafety/Services/PromptShield/PromptShieldAnalysis.cs ================================================ // Copyright (c) Microsoft.

[![Watch the video](https://img.youtube.com/vi/la1UDNn3eP4/0.jpg)](https://aka.ms/m365caps-videointro) ### Live Demo of CAPs in Action [![Watch the video](https://img.youtube.com/vi/-D3KdiPySxw/0.jpg)](https://aka.ms/m365caps-videodemo) ## CAPS Public Roadmap Our timelines may be subject to changes, at this time our current GA release cycles are ![A screenshot of the CAPs Public Roadmap ](images/CAPs_PublicRoadmap.png) What to get going? Start your journey below! ## Use the CopilotAgentPluginDemoSample application to use and create Plugins for Gen AI experiences in Microsoft 365 ### Prerequisites - A Entra ID/ AAD administrator account capable of registering an Application. You can get a development tenant for free by joining the [Microsoft 365 Developer Program](https://developer.microsoft.com/microsoft-365/dev-program). - [Visual Studio Code](https://code.visualstudio.com/) - [Semantic Kernel](https://github.com/microsoft/semantic-kernel). ### How the sample application works The sample has the following features: - This is a Console Application. The user will open a terminal and issue a command "dotnet run demo" or "dotnet run demo --debug" for debug mode. - The user will then be presented with options to leverage platforms of "AzureOpenAI", "OpenAI", or locally with "Ollama" where the LLM is hosted. - The user will then determine which Plugins they would like to load for this sample. As of this writing there are 4 available, Contacts, Messages, Calendar, and DriveItems. - Once loaded the user will then have options to inspect the Manifest, Plugins, or run a prompt using the "Execute a Goal" option. - The user will enter a prompt that satisfies one or more of the plugins they loaded. - If a Auth token is not present, the user will be prompted to sign in with their Microsoft 365 account. This demonstrates how to use delegated authentication to run on a user's behalf. - The users prompt is reasoned over and a result is returned with a description of the actions taken or data retrieved. This demonstrates how to use app can reason over Microsoft 365 data and synthesize a response or take an action on the users behalf. - The user then has the option to issue another prompt load additional plugins, or exit the application. ## Setting up the sample 1. Register a Microsoft Identity platform application, and give it the right permissions. 1. Create an applications.Development.json file that fits with the pattern in the sample applications.json file that is included in the sample ### Register a Microsoft Identity platform application #### Choose the tenant where you want to create your app 1. Sign in to the [Azure Active Directory admin center](https://aad.portal.azure.com) using either a work or school account. 1. If your account is present in more than one Azure AD tenant: 1. Select your profile from the menu on the top right corner of the page, and then **Switch directory**. 1. Change your session to the Azure AD tenant where you want to create your application. #### Register the app This sample for demonstration purposes uses a [Device Code Authentication flow](https://learn.microsoft.com/en-us/entra/identity-platform/msal-authentication-flows#device-code), however you may choose an Authentication Flow that suits your specific scenario. You will need to adjust the Authentication class "BearerAuthenticationProviderWithCancellationToken.cs" if you do so, in order for the sample to work as-is. 1. Select **Azure Active Directory** in the left-hand navigation, then select [App registrations](https://go.microsoft.com/fwlink/?linkid=2083908) under **Manage**. ![A screenshot of the App registrations ](images/aad-portal-app-registrations.png) 1. In creating a **New Application**.Ensure the below values are set appropriately according to your Authentication Flow. The below is for device code. - Provide an appropriate name for your sample and copy down the **Application(client)ID** as well as the **Directory(tenant)ID** and save them for later. ![A screenshot of the Register an application page](images/ApplicationOverViewScreenClientIDetc.png) - Set **Supported account types** to **Accounts in this organizational directory only**. This ensures that your App only will authenticate users from this tenant only. - Under **Redirect URI**, ensure the value is set to `http://localhost`. ![A screenshot of the RedirectURI an application page](images/AppRegistration_Authentication_localhostredirecturi.png) 1. In **Certificates & secrets** under **Manage**. Select the **New client secret** button. Enter a value in **Description** and select one of the options for **Expires** and select **Add**. 1. Copy the **Value** of the new secret **before** you leave this page. It will never be displayed again. Save the value for later. ![A screenshot of a new secret in the Client secrets list](images/AppRegistration_AppSecret.png) 1. Under **API permissions** under **Manage**. 1. In the list of pages for the app, select **API permissions**, then select **Add a permission**. 1. In this sample we selected the delegated permissions you see below. In order for the hand rolled plugins to work, at a minimum you will need to ensure that the Mail, Calendar, Files, and Contacts are selected as shown, with at least Read Permissions. 1. Make sure that the **Microsoft APIs** tab is selected, then select **Microsoft Graph**. 1. Select **Application permissions**, then find and enable your desired permissions. > **Note:** To create subscriptions for other resources you need to select different permissions as documented [here](https://docs.microsoft.com/graph/api/subscription-post-subscriptions#permissions) 1. Select **Grant admin consent for `name of your organization`** and **Yes**. This grants consent to the permissions of the application registration you just created to the current organization. ![A screenshot of a new secret in the Client secrets list](images/AppRegistration_APIPermissions.png) ### Update appsettings Development File 1. Rename the [appsettings.json](CopilotAgentPluginsDemoSample/appsettings.json) file to `appsettings.Development.json`. Open the file in Visual Studio code or any text editor. 1. Update the following values. - `TenantId`: set to the tenant ID from your app registration - `ClientId`: set to the client ID from your app registration - `ClientSecret`: set to the client secret from your app registration - `RedirectUri`: set to the http://localhost - `OpenAI`: if you are using OpenAI as your LLM provider ensure that the - `ApiKey` : is filled out - `ModelId` : is filled out - `AzureOpenAI` : if you are using AzureOpenAI as your LLM provider ensure that the - `ChatModelId` : is filled out - `ChatDeploymentName` : is filled out - `Endpoint` : is filled out - `ApiKey` : is filled out ### Start the application Open the repository with Visual Studio Code. Open a **New Terminal** and type. To run without Debug Mode type: ```shell dotnet run demo ``` To run with Debug Mode type: ```shell dotnet run demo --debug ``` Then follow the instructions provided. ## Troubleshooting See the dedicated [troubleshooting page](./TROUBLESHOOTING.md). ## Questions and comments We'd love to get your feedback about the Copilot Agent Plugins sample for Semantic Kernel.

These images are then displayed in the initial window as soon as the application launches. The application provides an interactive feature where you can click on each image. Upon clicking, the application employs the Semantic Kernel's HuggingFace ImageToText Service to fetch a descriptive analysis of the clicked image. A critical aspect of the implementation is how the application captures the binary content of the image and sends a request to the Service, awaiting the descriptive text. This process is a key highlight, showcasing the seamless integration and powerful capabilities of our latest software enhancement. Required packages to use ImageToText HuggingFace Service: - Microsoft.SemanticKernel - Microsoft.SemanticKernel.Connectors.HuggingFace The following code snippet below shows the most important pieces of code on how to use the ImageToText Service (Hugging Face implementation) to retrieve the descriptive text of an image: ```csharp // Initializes the Kernel var kernel = Kernel.CreateBuilder() .AddHuggingFaceImageToText("Salesforce/blip-image-captioning-base") .Build(); // Gets the ImageToText Service var service = this._kernel.GetRequiredService(); ``` Once one of the images is selected, the binary data of the image is retrieved and sent to the ImageToText Service. The service then returns the descriptive text of the image. The following code snippet demonstrates how to use the ImageToText Service to retrieve the descriptive text of an image: ```csharp // Get the binary content of a JPEG image: var imageBinary = File.ReadAllBytes("path/to/file.jpg"); // Prepare the image to be sent to the LLM var imageContent = new ImageContent(imageBinary) { MimeType = "image/jpeg" }; // Retrieves the image description var textContent = await service.GetTextContentAsync(imageContent); ``` ================================================ FILE: dotnet/samples/Demos/ModelContextProtocolClientServer/MCPClient/Extensions/AuthorRoleExtensions.cs ================================================ // Copyright (c) Microsoft.

This under-development manual will, some glorious day, provide comprehensive information on how the Linux virtual filesystem (VFS) layer works, along with the filesystems that sit below it. For now, what we have can be found below. Semantic Kernel allows prompts to be automatically converted to ChatHistory instances. Developers can create prompts which include tags and ... Anatomy of a plugin. At a high-level, a plugin is a group of functions that can be exposed to AI apps and services. The functions within plugins can then be orchestrated by an AI application to accomplish user requests. Within Semantic Kernel, you can invoke these functions automatically with function calling. Note. The biggest benefit of having a dedicated connector for Ollama is that it allows us to support Semantic Kernel features that targeted for Ollama deployed models. What is Ollama? Ollama is an open-source MIT license platform that facilitates the local operation of AI models directly on personal or corporate hardware. ================================================ FILE: dotnet/samples/Demos/ModelContextProtocolClientServer/MCPServer/Prompts/PromptDefinition.cs ================================================ // Copyright (c) Microsoft.

How to create an MCP server powered by SK: - Expose SK plugins as MCP tools. - Expose SK prompt templates as MCP prompts. - Use Kernel Function as MCP `Read` resource handlers. - Use Kernel Function as MCP `Read` resource template handlers. 2. How a hosting app can use MCP client and SK: - Import MCP tools as SK functions and utilize them via the Chat Completion service. - Use MCP prompts as additional context for prompting. - Use MCP resources and resource templates as additional context for prompting. - Intercept and handle sampling requests from the MCP server in human-in-the-loop scenarios. - Import MCP tools as SK functions and utilize them via Chat Completion and Azure AI agents. Please refer to the [MCP introduction](https://modelcontextprotocol.io/introduction) to get familiar with the protocol. ## Configuring Secrets or Environment Variables The samples require credentials and other secrets to access AI models. If you have set up those credentials as secrets within Secret Manager or through environment variables for other samples from the solution in which this project is found, they will be re-used. ### Set Secrets with Secret Manager ```text cd dotnet/samples/Demos/ModelContextProtocolClientServer/MCPClient dotnet user-secrets init dotnet user-secrets set "OpenAI:ChatModelId" "..." dotnet user-secrets set "OpenAI:ApiKey" "..." dotnet user-secrets set "AzureAI:ConnectionString" "..." dotnet user-secrets set "AzureAI:ChatModelId" "..." ``` ### Set Secrets with Environment Variables Use these names: ```text # OpenAI OpenAI__ChatModelId OpenAI__ApiKey AzureAI__ConnectionString AzureAI__ChatModelId ``` ## Run the Sample To run the sample, follow these steps: 1. Right-click on the `MCPClient` project in Visual Studio and select `Set as Startup Project`. 2. Press `F5` to run the project. 3. All samples will be executed sequentially. You can find the output in the console window. 4. You can run individual samples by commenting out the other samples in the `Main` method of the `Program.cs` file of the `MCPClient` project. ## Use MCP Inspector and Claude desktop app to access the MCP server Both the MCP Inspector and the Claude desktop app can be used to access MCP servers for exploring and testing MCP server capabilities: tools, prompts, resources, etc. ### MCP Inspector To use the [MCP Inspector](https://modelcontextprotocol.io/docs/tools/inspector) follow these steps: 1. Open a terminal in the MCPServer project directory. 2. Run the `npx @modelcontextprotocol/inspector dotnet run` command to start the MCP Inspector. Make sure you have [node.js](https://nodejs.org/en/download/) and npm installed ```bash npx @modelcontextprotocol/inspector dotnet run ``` 3. When the inspector is running, it will display a URL in the terminal, like this: ``` MCP Inspector is up and running at http://127.0.0.1:6274 ``` 4. Open a web browser and navigate to the URL displayed in the terminal. This will open the MCP Inspector interface. 5. Find and click the "Connect" button in the MCP Inspector interface to connect to the MCP server. 6. As soon as the connection is established, you will see a list of available tools, prompts, and resources in the MCP Inspector interface. ### Claude Desktop App To use the [Claude desktop app](https://claude.ai/) to access the MCP server, follow these steps: 1. 1. Download and install the app from the [Claude website](https://claude.ai/download). 2. In the app, go to File->Settings->Developer->Edit Config. 3. Open the `claude_desktop_config.json` file in a text editor and add the following configuration to the file: ```Json { "mcpServers": { "demo_mcp_server": { "command": "/dotnet/samples/Demos/ModelContextProtocolClientServer/MCPServer/bin/Debug/net8.0/MCPServer.exe", "args": [] } } } ``` 4. Save the file and restart the app. ## Debugging the MCP Server To debug the MCP server in Visual Studio, follow these steps: 1. Connect to the MCP server using either the MCP Inspector or the Claude desktop app. This should start the MCP server process. 2. Set breakpoints in the MCP server code where you want to debug. 3. In Visual Studio, go to `Debug` -> `Attach to Process`. 4. In the `Attach to Process` dialog, find the `MCPServer.exe` process and select it. 5. Click `Attach` to attach the debugger to the process. 6. Once the debugger is attached, access the MCP server tools, prompts, or resources using the MCP Inspector or the Claude desktop app. This will trigger the breakpoints you set in the MCP server code. ## Remote MCP Server The MCP specification supports remote MCP servers. You can find more information at the following links: [Server-Side Events (SSE)](https://modelcontextprotocol.io/docs/concepts/transports#server-sent-events-sse) and [HTTP with SSE](https://modelcontextprotocol.io/specification/2024-11-05/basic/transports#http-with-sse). The [MCP C# SDK](https://github.com/modelcontextprotocol/csharp-sdk) provides all the necessary components to easily create a remote MCP server. To get started, follow this sample: [AspNetCoreSseServer](https://github.com/modelcontextprotocol/csharp-sdk/tree/main/samples/AspNetCoreSseServer). ## Authentication While details of native support for OAuth 2.1 are [still being discussed](https://github.com/modelcontextprotocol/modelcontextprotocol/pull/284), you can consider a solution based on APIM acting as an [AI Gateway](https://github.com/Azure-Samples/AI-Gateway). This approach is demonstrated by the sample: [Secure Remote Microsoft Graph MCP Servers using Azure API Management (Experimental)](https://github.com/Azure-Samples/remote-mcp-apim-appservice-dotnet). ================================================ FILE: dotnet/samples/Demos/ModelContextProtocolPlugin/ModelContextProtocolPlugin.csproj ================================================  Exe net10.0 enable enable 5ee045b0-aea3-4f08-8d31-32d1a6f8fed0 $(NoWarn);CA2249;CS0612;SKEXP0001;VSTHRD111;CA2007 ================================================ FILE: dotnet/samples/Demos/ModelContextProtocolPlugin/Program.cs ================================================ // Copyright (c) Microsoft.

MCP is an open protocol that standardizes how applications provide context to LLMs. For information on Model Context Protocol (MCP) please refer to the [documentation](https://modelcontextprotocol.io/introduction). The sample shows: 1. How to connect to a protected MCP Server using OAuth 2.0 authentication 1. How to implement a custom OAuth authorization flow with browser-based authentication 1. Retrieve the list of tools the MCP Server makes available 1. Convert the MCP tools to Semantic Kernel functions so they can be added to a Kernel instance 1. Invoke the tools from Semantic Kernel using function calling ## Installing Prerequisites - A self-signed certificate to enable HTTPS use in development, see [dotnet dev-certs](https://learn.microsoft.com/en-us/dotnet/core/tools/dotnet-dev-certs) - .NET 10.0 or later - A running TestOAuthServer (for OAuth authentication), see [Start the Test OAuth Server](https://github.com/modelcontextprotocol/csharp-sdk/tree/main/samples/ProtectedMCPClient#step-1-start-the-test-oauth-server) - A running ProtectedMCPServer (for MCP services), see [Start the Protected MCP Server](https://github.com/modelcontextprotocol/csharp-sdk/tree/main/samples/ProtectedMCPClient#step-2-start-the-protected-mcp-server) ## Configuring Secrets or Environment Variables The example requires credentials to access OpenAI. If you have set up those credentials as secrets within Secret Manager or through environment variables for other samples from the solution in which this project is found, they will be re-used. ### To set your secrets with Secret Manager ```text cd dotnet/samples/Demos/ModelContextProtocolPluginAuth dotnet user-secrets init dotnet user-secrets set "OpenAI:ChatModelId" "..." dotnet user-secrets set "OpenAI:ApiKey" "..." "..." ``` ### To set your secrets with environment variables Use these names: ```text # OpenAI OpenAI__ChatModelId OpenAI__ApiKey ``` ## Setup and Running ### Step 1: Start the Test OAuth Server First, you need to start the TestOAuthServer which provides OAuth authentication: ```bash cd \tests\ModelContextProtocol.TestOAuthServer dotnet run --framework net10.0 ``` The OAuth server will start at `https://localhost:7029` ### Step 2: Start the Protected MCP Server Next, start the ProtectedMCPServer which provides the weather tools: ```bash cd \samples\ProtectedMCPServer dotnet run ``` The protected server will start at `http://localhost:7071` ### Step 3: Run the ModelContextProtocolPluginAuth sample Finally, run this client: ```bash dotnet run ``` ## What Happens 1. The client attempts to connect to the protected MCP server at `http://localhost:7071` 2. The server responds with OAuth metadata indicating authentication is required 3. The client initiates OAuth 2.0 authorization code flow: - Opens a browser to the authorization URL at the OAuth server - Starts a local HTTP listener on `http://localhost:1179/callback` to receive the authorization code - Exchanges the authorization code for an access token 4. The client uses the access token to authenticate with the MCP server 5. The client lists available tools and calls the `GetAlerts` tool for New York state The following diagram outlines an example OAuth flow: ```mermaid sequenceDiagram participant Client as Client participant Server as MCP Server (Resource Server) participant AuthServer as Authorization Server Client->>Server: MCP request without access token Server-->>Client: HTTP 401 Unauthorized with WWW-Authenticate header Note over Client: Analyze and delegate tasks Client->>Server: GET /.well-known/oauth-protected-resource Server-->>Client: Resource metadata with authorization server URL Note over Client: Validate RS metadata, build AS metadata URL Client->>AuthServer: GET /.well-known/oauth-authorization-server AuthServer-->>Client: Authorization server metadata Note over Client,AuthServer: OAuth 2.0 authorization flow happens here Client->>AuthServer: Token request AuthServer-->>Client: Access token Client->>Server: MCP request with access token Server-->>Client: MCP response Note over Client,Server: MCP communication continues with valid token ``` ## OAuth Configuration The client is configured with: - **Client ID**: `demo-client` - **Client Secret**: `demo-secret` - **Redirect URI**: `http://localhost:1179/callback` - **OAuth Server**: `https://localhost:7029` - **Protected Resource**: `http://localhost:7071` ## Available Tools Once authenticated, the client can access weather tools including: - **GetAlerts**: Get weather alerts for a US state - **GetForecast**: Get weather forecast for a location (latitude/longitude) ## Troubleshooting - Ensure the ASP.NET Core dev certificate is trusted. ``` dotnet dev-certs https --clean dotnet dev-certs https --trust ``` - Ensure all three services are running in the correct order - Check that ports 7029, 7071, and 1179 are available - If the browser doesn't open automatically, copy the authorization URL from the console and open it manually - Make sure to allow the OAuth server's self-signed certificate in your browser ================================================ FILE: dotnet/samples/Demos/OllamaFunctionCalling/OllamaFunctionCalling.csproj ================================================  Exe net10.0 $(NoWarn);CA2007,CA2208,CS1591,CA1024,IDE0009,IDE0055,IDE0073,IDE0211,VSTHRD111,SKEXP0001 ================================================ FILE: dotnet/samples/Demos/OllamaFunctionCalling/Plugins/MyAlarmPlugin.cs ================================================ // Copyright (c) Microsoft.

Configuring the sample ### Downloading the Models For this example we chose Hugging Face as our repository for download of the local models, go to a directory of your choice where the models should be downloaded and run the following commands: ```powershell git clone https://huggingface.co/TaylorAI/bge-micro-v2 git clone https://huggingface.co/microsoft/Phi-3-mini-4k-instruct-onnx ``` > [!IMPORTANT] > Both `BGE-Micro-V2` and `Phi-3` models are too large to be downloaded by the `git clone` command alone if you don't have [git-lfs extension](https://git-lfs.com/) installed, for this you may need to download the models manually and overwrite the files in the cloned directories. - Manual download [BGE-Micro-V2](https://huggingface.co/TaylorAI/bge-micro-v2/resolve/main/onnx/model.onnx?download=true) (69 MB) - Manual download [Phi-3-Mini-4k CPU](https://huggingface.co/microsoft/Phi-3-mini-4k-instruct-onnx/resolve/main/cpu_and_mobile/cpu-int4-rtn-block-32/phi3-mini-4k-instruct-cpu-int4-rtn-block-32.onnx.data?download=true) (≈2.7 GB) Update the `Program.cs` file lines below with the paths to the models you downloaded in the previous step. ```csharp // Path to the folder of your downloaded ONNX PHI-3 model var chatModelPath = @"C:\path\to\huggingface\Phi-3-mini-4k-instruct-onnx\cpu_and_mobile\cpu-int4-rtn-block-32"; // Path to the file of your downloaded ONNX BGE-MICRO-V2 model var embeddingModelPath = @"C:\path\to\huggingface\bge-micro-v2\onnx\model.onnx"; // Path to the vocab file your ONNX BGE-MICRO-V2 model var embeddingVocabPath = @"C:\path\to\huggingface\bge-micro-v2\vocab.txt"; ``` **Optional**: Change or add any fact text you want your AI to know about to the `facts` list in the `Program.cs` file. ```csharp foreach (var fact in new[] { "My fact 1.", "My fact 2." }) { ``` ## Configuring the sample The sample can be configured by using the command line with .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets) to avoid the risk of leaking secrets into the repository, branches and pull requests. ### Using .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets) ```powershell dotnet user-secrets set "Onnx:ModelId" ".. Onnx model id" (default: phi-3) dotnet user-secrets set "Onnx:ModelPath" ".. your Onnx model folder path .." dotnet user-secrets set "Onnx:EmbeddingModelPath" ".. your Onnx model file path .." dotnet user-secrets set "Onnx:EmbeddingVocabPath" ".. your Onnx model vocab file path .." ``` ## 3. Running the sample After configuring the sample, to build and run the console application just hit `F5`. To build and run the console application from the terminal use the following commands: ```powershell dotnet build dotnet run ``` Ask to the Model any question you want, the AI will try to answer based on the facts you provided. ### Example of a conversation > **User** > What is semantic kernel SDK used for? > **Assistant** > The Semantic Kernel SDK is used for developing AI agents and integrating the latest AI models into your C#, Python, or Java codebase.

Northwind Standard offre un'ampia varietà di fornitori in convenzione, tra cui medici di base, specialisti, ospedali e farmacie. Questo ti permette di scegliere un fornitore comodo per te e la tua famiglia, contribuendo al contempo a mantenere bassi i tuoi costi. Se scegli un fornitore in convenzione con il tuo piano, pagherai generalmente copay e franchigie più basse rispetto a un fornitore fuori rete. Inoltre, molti servizi, come l'assistenza preventiva, possono essere coperti senza alcun costo aggiuntivo se ricevuti da un fornitore in convenzione. È importante notare, tuttavia, che Northwind Standard non copre i servizi di emergenza, l'assistenza per la salute mentale e l'abuso di sostanze, né i servizi fuori rete. Questo significa che potresti dover pagare di tasca tua per questi servizi se ricevuti da un fornitore fuori rete. Quando scegli un fornitore in convenzione, ci sono alcuni suggerimenti da tenere a mente. Verifica che il fornitore sia in convenzione con il tuo piano. Puoi confermarlo chiamando l'ufficio del fornitore e chiedendo se è in rete con Northwind Standard. Puoi anche utilizzare lo strumento di ricerca fornitori sul sito web di Northwind Health per verificare la copertura. Assicurati che il fornitore stia accettando nuovi pazienti. Alcuni fornitori potrebbero essere in convenzione ma non accettare nuovi pazienti. Considera la posizione del fornitore. Se il fornitore è troppo lontano, potrebbe essere difficile raggiungere gli appuntamenti. Valuta gli orari dell'ufficio del fornitore. Se lavori durante il giorno, potresti aver bisogno di trovare un fornitore con orari serali o nel fine settimana. Scegliere un fornitore in convenzione può aiutarti a risparmiare sui costi sanitari. Seguendo i suggerimenti sopra e facendo ricerche sulle opzioni disponibili, puoi trovare un fornitore conveniente, accessibile e in rete con il tuo piano Northwind Standard." } ); return Results.Ok("Process completed successfully"); }); app.MapDefaultEndpoints(); app.Run(); ================================================ FILE: dotnet/samples/Demos/ProcessFrameworkWithAspire/ProcessFramework.Aspire/ProcessFramework.Aspire.ProcessOrchestrator/Steps/SummarizeStep.cs ================================================ // Copyright (c) Microsoft.

Northwind Standard offers a wide variety of in-network providers, ranging from primary care physicians, specialists, hospitals, and pharmacies. This allows you to choose a provider that is convenient for you and your family, while also helping you to keep your costs low. When you choose a provider that is in-network with your plan, you will typically pay lower copays and deductibles than you would with an out-of-network provider. In addition, many services, such as preventive care, may be covered at no cost when you receive care from an in-network provider. It is important to note, however, that Northwind Standard does not offer coverage for emergency services, mental health and substance abuse coverage, or out-of-network services. This means that you may have to pay out of pocket for these services if you receive them from an out-of-network provider. When choosing an in-network provider, there are a few tips to keep in mind. First, make sure that the provider you choose is in-network with your plan. You can confirm this by calling the provider's office and asking them if they are in-network with Northwind Standard. You can also use the provider search tool on the Northwind Health website to make sure your provider is in-network. Second, make sure that the provider you choose is accepting new patients. Some providers may be in-network but not be taking new patients. Third, consider the location of the provider. If the provider is too far away, it may be difficult for you to get to your appointments. Finally, consider the provider's office hours. If you work during the day, you may need to find a provider that has evening or weekend hours. Choosing an in-network provider can help you save money on your health care costs. By following the tips above and researching your options, you can find a provider that is convenient, affordable, and in-network with your Northwind Standard plan." } ### ================================================ FILE: dotnet/samples/Demos/ProcessFrameworkWithAspire/ProcessFramework.Aspire/ProcessFramework.Aspire.SummaryAgent/Program.cs ================================================ // Copyright (c) Microsoft.

Northwind Standard offre un'ampia varietà di fornitori in convenzione, tra cui medici di base, specialisti, ospedali e farmacie. Questo ti permette di scegliere un fornitore comodo per te e la tua famiglia, contribuendo al contempo a mantenere bassi i tuoi costi. Se scegli un fornitore in convenzione con il tuo piano, pagherai generalmente copay e franchigie più basse rispetto a un fornitore fuori rete. Inoltre, molti servizi, come l'assistenza preventiva, possono essere coperti senza alcun costo aggiuntivo se ricevuti da un fornitore in convenzione. È importante notare, tuttavia, che Northwind Standard non copre i servizi di emergenza, l'assistenza per la salute mentale e l'abuso di sostanze, né i servizi fuori rete. Questo significa che potresti dover pagare di tasca tua per questi servizi se ricevuti da un fornitore fuori rete. Quando scegli un fornitore in convenzione, ci sono alcuni suggerimenti da tenere a mente. Verifica che il fornitore sia in convenzione con il tuo piano. Puoi confermarlo chiamando l'ufficio del fornitore e chiedendo se è in rete con Northwind Standard. Puoi anche utilizzare lo strumento di ricerca fornitori sul sito web di Northwind Health per verificare la copertura. Assicurati che il fornitore stia accettando nuovi pazienti. Alcuni fornitori potrebbero essere in convenzione ma non accettare nuovi pazienti. Considera la posizione del fornitore. Se il fornitore è troppo lontano, potrebbe essere difficile raggiungere gli appuntamenti. Valuta gli orari dell'ufficio del fornitore. Se lavori durante il giorno, potresti aver bisogno di trovare un fornitore con orari serali o nel fine settimana. Scegliere un fornitore in convenzione può aiutarti a risparmiare sui costi sanitari. Seguendo i suggerimenti sopra e facendo ricerche sulle opzioni disponibili, puoi trovare un fornitore conveniente, accessibile e in rete con il tuo piano Northwind Standard." } ### ================================================ FILE: dotnet/samples/Demos/ProcessFrameworkWithAspire/ProcessFramework.Aspire/ProcessFramework.Aspire.TranslatorAgent/Program.cs ================================================ // Copyright (c) Microsoft.

The Process Framework enables the creation of business processes based on events, where each process step may invoke an agent or execute native code. In the demo, agents are defined as **external services**. Each process step issues an HTTP request to call these agents, allowing .NET Aspire to trace the process using **OpenTelemetry**. Furthermore, because each agent is a standalone service, they can be restarted independently via the .NET Aspire developer dashboard. ## Architecture The business logic of this sample is straightforward: it defines a process that translates text from English and subsequently summarizes it. ![Architecture Diagram](./docs/architecture.png) ## What is .NET Aspire? .NET Aspire is a set of tools, templates, and packages for building observable, production ready apps. .NET Aspire is delivered through a collection of NuGet packages that bootstrap or improve common challenges in modern app development. Key features include: - Dev-Time Orchestration: provides features for running and connecting multi-project applications, container resources, and other dependencies for local development environments. - Integrations: offers standardized NuGet packages for frequently used services such as Redis and Postgres, with standardized interfaces ensuring they consistent and seamless connectivity. - Tooling: includes project templates and tools for Visual Studio, Visual Studio Code, and the .NET CLI to help creating and interacting with .NET Aspire projects. .NET Aspire orchestration assists with the following concerns: - App composition: specify the .NET projects, containers, executables, and cloud resources that make up the application. - Service Discovery and Connection String Management: automatically injects the right connection strings, network configurations, and service discovery information to simplify the developer experience. ### Running with .NET Aspire To run this sample with .NET Aspire, clone the repository and execute the following commands: ```bash cd scr/ProcessFramework.Aspire/ProcessFramework.Aspire.AppHost dotnet run ``` A dashboard will then be displayed in the browser, similar to this: ![Aspire Dashboard](./docs/aspire-dashboard.png) By invoking the `ProcessOrchestrator` service, the process can be started. A predefined request is available in [`ProcessFramework.Aspire.ProcessOrchestrator.http``](./ProcessFramework.Aspire/ProcessFramework.Aspire.ProcessOrchestrator/ProcessFramework.Aspire.ProcessOrchestrator.http). This will generate a trace in the Aspire dashboard that looks like this: ![Aspire Trace](./docs/aspire-traces.png) Additionally, the metrics for each agent can be monitored in the Metrics tab: ![Aspire Metrics](./docs/aspire-metrics.png) ================================================ FILE: dotnet/samples/Demos/ProcessFrameworkWithSignalR/.gitignore ================================================ ## Ignore Visual Studio temporary files, build results, and ## files generated by popular Visual Studio add-ons. ## ## Get latest from https://github.com/github/gitignore/blob/main/VisualStudio.gitignore # User-specific files *.rsuser *.suo *.user *.userosscache *.sln.docstates */*.Development.Json # User-specific files (MonoDevelop/Xamarin Studio) *.userprefs # Mono auto generated files mono_crash.* # Build results [Dd]ebug/ [Dd]ebugPublic/ [Rr]elease/ [Rr]eleases/ x64/ x86/ [Ww][Ii][Nn]32/ [Aa][Rr][Mm]/ [Aa][Rr][Mm]64/ bld/ [Bb]in/ [Oo]bj/ [Ll]og/ [Ll]ogs/ # Visual Studio 2015/2017 cache/options directory .vs/ # Uncomment if you have tasks that create the project's static files in wwwroot #wwwroot/ # Visual Studio 2017 auto generated files Generated\ Files/ # MSTest test Results [Tt]est[Rr]esult*/ [Bb]uild[Ll]og.* # NUnit *.VisualState.xml TestResult.xml nunit-*.xml # Build Results of an ATL Project [Dd]ebugPS/ [Rr]eleasePS/ dlldata.c # Benchmark Results BenchmarkDotNet.Artifacts/ # .NET Core project.lock.json project.fragment.lock.json artifacts/ # ASP.NET Scaffolding ScaffoldingReadMe.txt # StyleCop StyleCopReport.xml # Files built by Visual Studio *_i.c *_p.c *_h.h *.ilk *.meta *.obj *.iobj *.pch *.pdb *.ipdb *.pgc *.pgd *.rsp *.sbr *.tlb *.tli *.tlh *.tmp *.tmp_proj *_wpftmp.csproj *.log *.tlog *.vspscc *.vssscc .builds *.pidb *.svclog *.scc # Chutzpah Test files _Chutzpah* # Visual C++ cache files ipch/ *.aps *.ncb *.opendb *.opensdf *.sdf *.cachefile *.VC.db *.VC.VC.opendb # Visual Studio profiler *.psess *.vsp *.vspx *.sap # Visual Studio Trace Files *.e2e # TFS 2012 Local Workspace $tf/ # Guidance Automation Toolkit *.gpState # ReSharper is a .NET coding add-in _ReSharper*/ *.[Rr]e[Ss]harper *.DotSettings.user # TeamCity is a build add-in _TeamCity* # DotCover is a Code Coverage Tool *.dotCover # AxoCover is a Code Coverage Tool .axoCover/* !.axoCover/settings.json # Coverlet is a free, cross platform Code Coverage Tool coverage*.json coverage*.xml coverage*.info # Visual Studio code coverage results *.coverage *.coveragexml # NCrunch _NCrunch_* .*crunch*.local.xml nCrunchTemp_* # MightyMoose *.mm.* AutoTest.Net/ # Web workbench (sass) .sass-cache/ # Installshield output folder [Ee]xpress/ # DocProject is a documentation generator add-in DocProject/buildhelp/ DocProject/Help/*.HxT DocProject/Help/*.HxC DocProject/Help/*.hhc DocProject/Help/*.hhk DocProject/Help/*.hhp DocProject/Help/Html2 DocProject/Help/html # Click-Once directory publish/ # Publish Web Output *.[Pp]ublish.xml *.azurePubxml # Note: Comment the next line if you want to checkin your web deploy settings, # but database connection strings (with potential passwords) will be unencrypted *.pubxml *.publishproj # Microsoft Azure Web App publish settings.

A custom server is created that launches the creation of a SK Process with a specific process id and a specific input event. 2. A custom implementation of the `IExternalKernelProcessMessageChannel` is injected containing the custom implementation of the Cloud Event channel to be used. The custom implementation must include: - `Initialize`: Initial setup to start the connection with the server. - `Uninitialize`: Logic needed to close the connection with the server. - `EmitExternalEventAsync`: Logic to send an external event to the server. This may include internal mapping of SK topics to specific server exposed methods. 3. Use of the `ProxyStep` in the `ProcessBuilder` to emit external events on specific SK Events.
    Example: ``` csharp var proxyStep = processBuilder.AddProxyStep([DocGenerationTopics.RequestUserReview, DocGenerationTopics.PublishDocumentation]); ... docsPublishStep .OnFunctionResult() .EmitExternalEvent(proxyStep, DocGenerationTopics.PublishDocumentation); ``` ## Usage 1. Run the server running the SK Process using a specific Cloud Event technology 2.

Navigate to the project directory: ```bash cd /dotnet/samples/Demos/ProcessWithCloudEvents/ProcessWithCloudEvents.Client ``` 2. Install the dependencies: ```bash yarn install ``` Alternatively, you can use the existing Visual Studio Code task: 1. Open the Command Palette in Visual Studio Code (`Ctrl+Shift+P` or `Cmd+Shift+P` on macOS). 2. Search for and select `Tasks: Run Task`. 3. Choose the `yarn: install` task from the list to install the dependencies. ### Running the Application 1. Ensure that the backend server is running. 2. Start the development server: ```bash yarn: run dev ``` Alternatively, you can use the existing Visual Studio Code task `yarn: run dev`. 3. Open your browser and navigate to `http://localhost:5173` to view the app. ### Usage 1. Select cloud technology to be used. 2. Select SK Process to be used. 3. Interact with the UI to send events/messages to the backend. The UI will display any incoming events/messages from the backend. 4. Use the provided buttons/inputs to trigger specific actions or events as needed. ### Debugging 1. Run the application. 2. Start the app in debug mode: - If using Visual Studio Code, go to the "Run and Debug" panel and select `Launch Edge against localhost`. 3. Set breakpoints in your code to inspect and debug as needed.

Navigate to the project directory: ```bash cd /dotnet/samples/Demos/ProcessWithCloudEvents/ProcessWithCloudEvents.Client ``` 2. Install the dependencies: ```bash yarn install ``` Alternatively, you can use the existing Visual Studio Code task: 1. Open the Command Palette in Visual Studio Code (`Ctrl+Shift+P` or `Cmd+Shift+P` on macOS). 2. Search for and select `Tasks: Run Task`. 3. Choose the `yarn: install` task from the list to install the dependencies. ### Running the Application 1. Ensure that the backend server is running. 2. Start the development server: ```bash yarn: run dev ``` Alternatively, you can use the existing Visual Studio Code task `yarn: run dev`. 3. Open your browser and navigate to `http://localhost:5173` to view the app. ### Usage 1. Select cloud technology to be used. 2. Select SK Process to be used. 3. Interact with the UI to send events/messages to the backend. The UI will display any incoming events/messages from the backend. 4. Use the provided buttons/inputs to trigger specific actions or events as needed. ### Debugging 1. Run the application. 2. Start the app in debug mode: - If using Visual Studio Code, go to the "Run and Debug" panel and select `Launch Edge against localhost`. 3. Set breakpoints in your code to inspect and debug as needed.

Which for this demo means: - Making use of `builder.Services.AddGrpcReflection()` and `app.MapGrpcReflectionService()` - Making use of [`gRPCui`](https://github.com/fullstorydev/grpcui) for testing ## Explanation This demo showcases how SK Process Framework could interact with a gRPC Server and clients. The main difference of this demo is the custom implementation of the gRPC Server and client used internally by the SK Process in the SK Proxy Step. Main gRPC components: - `documentationGenerator.proto`: `\dotnet\samples\Demos\ProcessWithCloudEvents\ProcessWithCloudEvents.Grpc\Protos\documentationGenerator.proto` - gRPC Server: `\dotnet\samples\Demos\ProcessWithCloudEvents\ProcessWithCloudEvents.Grpc\Services\DocumentGenerationService.cs` - gRPC Client/IExternalKernelProcessMessageChannel implementation: `\dotnet\samples\Demos\ProcessWithCloudEvents\ProcessWithCloudEvents.Grpc\Clients\DocumentGenerationGrpcClient.cs` ### SK Process and gRPC Events ``` mermaid sequenceDiagram participant grpcClient as gRPC Client box Server participant grpcServer as gRPC Server participant SKP as SK Process end grpcClient->>grpcServer: UserRequestFeatureDocumentation

    PublishDocumentation (gRPC) grpcServer->>grpcClient: ReceivePublishedDocumentation
    gRPC ``` 1. When the `UserRequestFeatureDocumentation` gRPC request is received from the gRPC client, the server initiates an SK Process and emits the `StartDocumentGeneration` SK event. 2. The `RequestUserReview` topic is emitted when the `DocumentationApproved` event is triggered during the `ProofReadDocumentationStep`. This event invokes the `RequestUserReviewDocumentationFromProcess` gRPC method to communicate with the server. 3. The `RequestUserReviewDocumentationFromProcess` method updates the shared stream, which is used to communicate with the subscribers of `RequestUserReviewDocumentation`. The gRPC client then receives the document for review and approval. 4. The gRPC client can approve or reject the document using the `UserReviewedDocumentation` method to communicate with the server. The server then sends the `UserApprovedDocument` or `UserRejectedDocument` SK event to the SK Process. 5. The SK Process resumes, and the `PublishDocumentationStep` now has all the necessary parameters to execute. Upon execution, the `PublishDocumentation` topic is triggered, invoking the `PublishDocumentation` method on the gRPC server. 6. The PublishDocumentation method updates the shared stream used by `ReceivePublishedDocumentation`, ensuring that all subscribers receive the update of the latest published document ## Demo ### Requirements - Have Dapr setup ready - Build and Run the app - Interact with the server by: - Install and run `gRPCui` listening to the address `localhost:58641`: ``` ./grpcui.exe -plaintext localhost:58641 ``` or - Use the `ProcessWithCloudEvents.Client` App and use it to interact with the server. This app uses gRPC Web, which interacts with the server through `localhost:58640`. ### Usage without UI For interacting with the gRPC server, the 1. Build and run the app 2. Open 2 windows of `gRPCui` with the following methods: - Window 1: - Method name: `UserRequestFeatureDocumentation` and `UserReviewedDocumentation` - Window 2: - Method name: `RequestUserReviewDocumentation` - Window 3: - Method name: `ReceivePublishedDocumentation` 3. Select a process id to be used with all methods. Example: processId = "100" 4. Execute different methods in the following order: 1. `RequestUserReviewDocumentation` with Request Data: ```json { "processId": "100" } ``` This will subscribe to any request for review done for the specific process id and a response will be received when the process emits a notification. Set timeout to 30 seconds. 2. `UserRequestFeatureDocumentation` with Request Data: ```json { "title": "some product title", "userDescription": "some user description", "content": "some product content", "processId": "100", } ``` This request will kickstart the creation of a new process with the specific processId passing an initial event to the SK process. 5. Once the `RequestUserReviewDocumentation` is received, execute the following methods: 1. `ReceivePublishedDocumentation` with Request Data: ```json { "processId": "100" } ``` This will subscribe to any request for review done for the specific process id and a response will be received when the process emits a notification. Set timeout to 30 seconds. 2. `UserReviewedDocumentation` with Request Data: ```json { "documentationApproved": true, "reason": "", "processData": { "processId": "100" } } ``` ### Debugging For debugging and be able to set breakpoints in different stages of the app, you can: - Install the [Visual Studio Dapr Extension](https://marketplace.visualstudio.com/items?itemName=ms-azuretools.vs-dapr) and make use of it by making use of the `\dotnet\dapr.yaml` file already in the repository. or - Set the `ProcessWithCloudEvents.Grpc` as startup app, run and attach the Visual Studio debugger: ``` dapr run --app-id processwithcloudevents-grpc --app-port 58640 --app-protocol http -- dotnet run --no-build ``` ================================================ FILE: dotnet/samples/Demos/ProcessWithCloudEvents/ProcessWithCloudEvents.Grpc/Services/DocumentGenerationService.cs ================================================ // Copyright (c) Microsoft.

A custom server is created that launches the creation of a SK Process with a specific process id and a specific input event. 2. A custom implementation of the `IExternalKernelProcessMessageChannel` is injected containing the custom implementation of the Cloud Event channel to be used. The custom implementation must include: - `Initialize`: Initial setup to start the connection with the server. - `Uninitialize`: Logic needed to close the connection with the server. - `EmitExternalEventAsync`: Logic to send an external event to the server. This may include internal mapping of SK topics to specific server exposed methods. 3. Use of the `ProxyStep` in the `ProcessBuilder` to emit external events on specific SK Events.
    Example: ``` csharp var proxyStep = processBuilder.AddProxyStep([DocGenerationTopics.RequestUserReview, DocGenerationTopics.PublishDocumentation]); ... docsPublishStep .OnFunctionResult() .EmitExternalEvent(proxyStep, DocGenerationTopics.PublishDocumentation); ``` ## Usage 1. Run the server running the SK Process using a specific Cloud Event technology 2. Launch the Client App to interact with the SK Process from a UI ================================================ FILE: dotnet/samples/Demos/ProcessWithDapr/Controllers/ProcessController.cs ================================================ // Copyright (c) Microsoft.

Dapr is a portable, event-driven runtime that can simplify the process of building resilient, stateful application that run in the cloud and/or edge. Dapr is a natural fit for hosting Semantic Kernel Processes and allows you to scale your processes in size and quantity without sacrificing performance, or reliability. For more information about Semantic Kernel Processes and Dapr, see the following documentation: #### Semantic Kernel Processes - [Overview of the Process Framework (docs)](https://learn.microsoft.com/semantic-kernel/frameworks/process/process-framework) - [Getting Started with Processes (samples)](../../GettingStartedWithProcesses/) #### Dapr - [Dapr documentation](https://docs.dapr.io/) - [Dapr Actor documentation](https://v1-10.docs.dapr.io/developing-applications/building-blocks/actors/) - [Dapr local development](https://docs.dapr.io/getting-started/install-dapr-selfhost/) ## Running the Demo Before running this Demo, make sure to configure Dapr for local development following the links above. The Dapr containers must be running for this demo application to run. ```mermaid flowchart LR Kickoff --> A Kickoff --> B A --> C B --> C C -->|Count < 3| Kickoff C -->|Count == 3| End classDef kickoffClass fill:#f9f,stroke:#333,stroke-width:2px; class Kickoff kickoffClass; End((End)) ``` 1. Build and run the sample. Running the Dapr service locally can be done using the Dapr Cli or with the Dapr VS Code extension. The VS Code extension is the recommended approach if you want to debug the code as it runs. 1. When the service is up and running, it will expose a single API in localhost port 5000. #### Invoking the process: 1. Open a web browser and point it to [http://localhost:5000/processes/1234](http://localhost:5000/processes/1234) to invoke a new process with `Id = "1234"` 1. You should see console output from the running service with logs that match the following: ```csharp ##### Kickoff ran. ##### AStep ran. ##### BStep ran. ##### CStep activated with Cycle = '1'. ##### CStep run cycle 2. ##### Kickoff ran. ##### AStep ran. ##### BStep ran. ##### CStep run cycle 3 - exiting. ``` Now refresh the page in your browser to run the same processes instance again. Now the logs should look like this: ```csharp ##### Kickoff ran. ##### AStep ran. ##### BStep ran. ##### CStep run cycle 3 - exiting. ``` Notice that the logs from the two runs are not the same. In the first run, the processes has not been run before and so it's initial state came from what we defined in the process: **_First Run_** - `CState` is initialized with `Cycle = 1` which is the initial state that we specified while building the process. - `CState` is invoked a total of two times before the terminal condition of `Cycle >= 3` is reached. In the second run however, the process has persisted state from the first run: **_Second Run_** - `CState` is initialized with `Cycle = 3` which is the final state from the first run of the process. - `CState` is invoked only once and is already in the terminal condition of `Cycle >= 3`. If you create a new instance of the process with `Id = "ABCD"` by pointing your browser to [http://localhost:5000/processes/ABCD](http://localhost:5000/processes/ABCD), you will see the it will start with the initial state as expected. ## Understanding the Code Below are the key aspects of the code that show how Dapr and Semantic Kernel Processes can be integrated into an ASP.Net Core Web Api: - Create a new ASP.Net web API project. - Add the required Semantic Kernel and Dapr packages to your project: **_Semantic Kernel Packages_** - `dotnet add package Microsoft.SemanticKernel --version 1.24.0` - `dotnet add package Microsoft.SemanticKernel.Process.Core --version 1.24.0-alpha` - `dotnet add package Microsoft.SemanticKernel.Process.Runtime.Dapr --version 1.24.0-alpha` **_Dapr Packages_** - `dotnet add package Dapr.Actors.AspNetCore --version 1.14.0` - Configure `program.cs` to use Dapr and the Process framework: ```csharp // Configure Dapr builder.Services.AddActors(static options => { // Register the actors required to run Processes options.AddProcessActors(); }); ``` - Build and run a Process as you normally would. For this Demo we run a simple example process from with a Controller's action method in response to a GET request.

Metrics used in this example: - [BERTScore](https://github.com/Tiiiger/bert_score) - leverages the pre-trained contextual embeddings from BERT and matches words in candidate and reference sentences by cosine similarity. - [BLEU](https://en.wikipedia.org/wiki/BLEU) (BiLingual Evaluation Understudy) - evaluates the quality of text which has been machine-translated from one natural language to another. - [METEOR](https://en.wikipedia.org/wiki/METEOR) (Metric for Evaluation of Translation with Explicit ORdering) - evaluates the similarity between the generated summary and the reference summary, taking into account grammar and semantics. - [COMET](https://unbabel.github.io/COMET) (Crosslingual Optimized Metric for Evaluation of Translation) - is an open-source framework used to train Machine Translation metrics that achieve high levels of correlation with different types of human judgments. In this example, SK Filters call dedicated [server](./python-server/) which is responsible for task evaluation using metrics described above. If evaluation score of specific metric doesn't meet configured threshold, an exception is thrown with evaluation details. [Hugging Face Evaluate Metric](https://github.com/huggingface/evaluate) library is used to evaluate summarization and translation results. ## Prerequisites 1. [Python 3.12](https://www.python.org/downloads/) 2. Get [Hugging Face API token](https://huggingface.co/docs/api-inference/en/quicktour#get-your-api-token). 3. Accept conditions to access [Unbabel/wmt22-cometkiwi-da](https://huggingface.co/Unbabel/wmt22-cometkiwi-da) model on Hugging Face portal. ## Setup It's possible to run Python server for task evaluation directly or with Docker. ### Run server 1. Open Python server directory: ```bash cd python-server ``` 2. Create and active virtual environment: ```bash python -m venv venv source venv/Scripts/activate # activate on Windows source venv/bin/activate # activate on Unix/MacOS ``` 3. Setup Hugging Face API key: ```bash pip install "huggingface_hub[cli]" huggingface-cli login --token ``` 4. Install dependencies: ```bash pip install -r requirements.txt ``` 5. Run server: ```bash cd app uvicorn main:app --port 8080 --reload ``` 6. Open `http://localhost:8080/docs` and check available endpoints. ### Run server with Docker 1. Open Python server directory: ```bash cd python-server ``` 2. Create following `Dockerfile`: ```dockerfile # syntax=docker/dockerfile:1.2 FROM python:3.12 WORKDIR /code COPY ./requirements.txt /code/requirements.txt RUN pip install "huggingface_hub[cli]" RUN --mount=type=secret,id=hf_token \ huggingface-cli login --token $(cat /run/secrets/hf_token) RUN pip install cmake RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt COPY ./app /code/app CMD ["fastapi", "run", "app/main.py", "--port", "80"] ``` 3. Create `.env/hf_token.txt` file and put Hugging Face API token in it. 4. Build image and run container: ```bash docker-compose up --build ``` 5. Open `http://localhost:8080/docs` and check available endpoints. ## Testing Open and run `QualityCheckWithFilters/Program.cs` to experiment with different evaluation metrics, thresholds and input parameters. ================================================ FILE: dotnet/samples/Demos/QualityCheck/python-server/app/__init__.py ================================================ ================================================ FILE: dotnet/samples/Demos/QualityCheck/python-server/app/main.py ================================================ # Copyright (c) Microsoft.

The new approach produces the results more reliably and uses fewer tokens compared to FunctionCallingStepwisePlanner. ## Prerequisites 1. [OpenAI](https://platform.openai.com/docs/introduction) subscription. 2. Update `appsettings.Development.json` file with your configuration for `OpenAI` section or use .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets) (recommended approach): ```powershell # OpenAI # Make sure to use the model which supports function calling capability. # Supported models: https://platform.openai.com/docs/guides/function-calling/supported-models dotnet user-secrets set "OpenAI:ChatModelId" "... your model ..." dotnet user-secrets set "OpenAI:ApiKey" "... your api key ... " ``` ## Testing 1. Start ASP.NET Web API application. 2. Open `StepwisePlannerMigration.http` file and run listed requests. It's possible to send [HTTP requests](https://learn.microsoft.com/en-us/aspnet/core/test/http-files?view=aspnetcore-8.0) directly from `StepwisePlannerMigration.http` with Visual Studio 2022 version 17.8 or later. For Visual Studio Code users, use `StepwisePlannerMigration.http` file as REST API specification and use tool of your choice to send described requests. ## Migration guide ### Plan generation Old approach: ```csharp Kernel kernel = Kernel .CreateBuilder() .AddOpenAIChatCompletion("gpt-4", Environment.GetEnvironmentVariable("OpenAI__ApiKey")) .Build(); FunctionCallingStepwisePlanner planner = new(); FunctionCallingStepwisePlannerResult result = await planner.ExecuteAsync(kernel, "Check current UTC time and return current weather in Boston city."); ChatHistory generatedPlan = result.ChatHistory; ``` New approach: ```csharp Kernel kernel = Kernel .CreateBuilder() .AddOpenAIChatCompletion("gpt-4", Environment.GetEnvironmentVariable("OpenAI__ApiKey")) .Build(); IChatCompletionService chatCompletionService = kernel.GetRequiredService(); ChatHistory chatHistory = []; chatHistory.AddUserMessage("Check current UTC time and return current weather in Boston city."); OpenAIPromptExecutionSettings executionSettings = new() { FunctionChoiceBehavior = FunctionChoiceBehavior.Auto() }; await chatCompletionService.GetChatMessageContentAsync(chatHistory, executionSettings, kernel); ChatHistory generatedPlan = chatHistory; ``` ### New plan execution Old approach: ```csharp Kernel kernel = Kernel .CreateBuilder() .AddOpenAIChatCompletion("gpt-4", Environment.GetEnvironmentVariable("OpenAI__ApiKey")) .Build(); FunctionCallingStepwisePlanner planner = new(); FunctionCallingStepwisePlannerResult result = await planner.ExecuteAsync(kernel, "Check current UTC time and return current weather in Boston city."); string planResult = result.FinalAnswer; ``` New approach: ```csharp Kernel kernel = Kernel .CreateBuilder() .AddOpenAIChatCompletion("gpt-4", Environment.GetEnvironmentVariable("OpenAI__ApiKey")) .Build(); OpenAIPromptExecutionSettings executionSettings = new() { FunctionChoiceBehavior = FunctionChoiceBehavior.Auto() }; FunctionResult result = await kernel.InvokePromptAsync("Check current UTC time and return current weather in Boston city.", new(executionSettings)); string planResult = result.ToString(); ``` ### Existing plan execution Old approach: ```csharp Kernel kernel = Kernel .CreateBuilder() .AddOpenAIChatCompletion("gpt-4", Environment.GetEnvironmentVariable("OpenAI__ApiKey")) .Build(); FunctionCallingStepwisePlanner planner = new(); ChatHistory existingPlan = GetExistingPlan(); // plan can be stored in database for reusability.

The demo shows how to perform database operations using natural language queries, which are translated into appropriate database commands. ## Semantic Kernel Features Used - Structured Data Plugin - Enables natural language interactions with databases - Entity Framework 6 Integration - Provides database access layer - OpenAI Function Calling - Used to parse natural language into structured database operations ## Prerequisites - OpenAI API key - Function Calling enabled model (e.g., gpt-4o) - Relational database (e.g., SQL Server) - .NET 10.0 or higher ## Database Setup 1. Create the Products table in your database: ```sql -- SQL Server example CREATE TABLE Products ( Id uniqueidentifier DEFAULT newsequentialid() NOT NULL, Name nvarchar(100) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL, Price decimal(18,2) NOT NULL, DateCreated datetime DEFAULT getdate() NOT NULL, CONSTRAINT Products_PK PRIMARY KEY (Id) ); ``` ## Key Components ### Product Entity The demo uses a `Product` entity as an example of structured data. This entity represents items in a database table named "Test1". ### ApplicationDbContext `ApplicationDbContext` is an Entity Framework Core database context that: - Inherits from `DbContext` - Configures database connection using either: - Configuration string from IConfiguration - Direct connection string - Disables database initialization - Maps the `Product` entity to the "Test1" table ### Connection String Setup You can configure the connection string using one of these methods: 1. Using appsettings.json: ```json { "ConnectionStrings": { "ApplicationDbContext": "your_connection_string" } } ``` 2. Using appsettings.Development.json (for development environment): ```json { "ConnectionStrings": { "ApplicationDbContext": "your_connection_string" } } ``` 3. Using user secrets (recommended for development): ```bash dotnet user-secrets set "ConnectionStrings:ApplicationDbContext" "your_connection_string" ``` 4. Using environment variables: ```bash set ConnectionStrings__ApplicationDbContext="your_connection_string" ``` The application uses the following configuration hierarchy (highest to lowest priority): 1. User Secrets 2. Environment Variables 3. appsettings.json ## Usage Examples The demo showcases various database operations using natural language: 1. Inserting new records: ```csharp var result = await kernel.InvokeAsync("Insert a new product with name 'Sample Product' and price 29.99"); ``` 2. Querying data: ```csharp var result = await kernel.InvokeAsync("Find all products under $50"); ``` 3. Updating records: ```csharp var result = await kernel.InvokeAsync("Update the price of 'Sample Product' to 39.99"); ``` 4. Deleting records: ```csharp var result = await kernel.InvokeAsync("Delete the product named 'Sample Product'"); ``` ## Important Notes - The plugin uses OpenAI's function calling feature to parse natural language into structured database operations - Database operations are performed through Entity Framework Core - The demo includes proper error handling and transaction management - Connection strings should be secured and not committed to source control - For production environments, consider using Azure Key Vault or similar secure configuration storage ## Additional Resources - [Entity Framework Core Documentation](https://learn.microsoft.com/en-us/ef/core/) - [Semantic Kernel Documentation](https://learn.microsoft.com/en-us/semantic-kernel/overview/) - [OpenAI Function Calling](https://platform.openai.com/docs/guides/function-calling) - [Safe Storage of App Secrets in Development](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets) ================================================ FILE: dotnet/samples/Demos/StructuredDataPlugin/StructuredDataPlugin.csproj ================================================  Exe net10.0 enable enable $(NoWarn),VSTHRD111,CA2007,CA5399,SKEXP0050 5ee045b0-aea3-4f08-8d31-32d1a6f8fed0 ================================================ FILE: dotnet/samples/Demos/StructuredDataPlugin/appsettings.json ================================================ { "ConnectionStrings": { "ApplicationDbContext": "your-connection-string-here" } } ================================================ FILE: dotnet/samples/Demos/TelemetryWithAppInsights/Program.cs ================================================ // Copyright (c) Microsoft.

AppContext switch: - `Microsoft.SemanticKernel.Experimental.GenAI.EnableOTelDiagnostics` - `Microsoft.SemanticKernel.Experimental.GenAI.EnableOTelDiagnosticsSensitive` 2. Environment variable - `SEMANTICKERNEL_EXPERIMENTAL_GENAI_ENABLE_OTEL_DIAGNOSTICS` - `SEMANTICKERNEL_EXPERIMENTAL_GENAI_ENABLE_OTEL_DIAGNOSTICS_SENSITIVE` > Enabling the collection of sensitive data including prompts and responses will implicitly enable the feature. ## Configuration ### Require resources 1. [Application Insights](https://learn.microsoft.com/en-us/azure/azure-monitor/app/create-workspace-resource) 2. [Azure OpenAI](https://learn.microsoft.com/en-us/azure/ai-services/openai/how-to/create-resource?pivots=web-portal) ### Secrets This example will require secrets and credentials to access your Application Insights instance and Azure OpenAI. We suggest using .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets) to avoid the risk of leaking secrets into the repository, branches and pull requests. You can also use environment variables if you prefer. To set your secrets with Secret Manager: ``` cd dotnet/samples/TelemetryExample dotnet user-secrets set "AzureOpenAI:ChatDeploymentName" "..." dotnet user-secrets set "AzureOpenAI:ChatModelId" "..." dotnet user-secrets set "AzureOpenAI:Endpoint" "https://... .openai.azure.com/" dotnet user-secrets set "AzureOpenAI:ApiKey" "..." dotnet user-secrets set "GoogleAI:Gemini:ModelId" "..." dotnet user-secrets set "GoogleAI:ApiKey" "..." dotnet user-secrets set "HuggingFace:ModelId" "..." dotnet user-secrets set "HuggingFace:ApiKey" "..." dotnet user-secrets set "MistralAI:ChatModelId" "mistral-large-latest" dotnet user-secrets set "MistralAI:ApiKey" "..." dotnet user-secrets set "ApplicationInsights:ConnectionString" "..." ``` ## Running the sample Simply run `dotnet run` under this directory if the command line interface is preferred. Otherwise, this example can also be run in Visual Studio. > This will output the Operation/Trace ID, which can be used later in Application Insights for searching the operation. ## Application Insights/Azure Monitor ### Logs and traces Go to your Application Insights instance, click on _Transaction search_ on the left menu. Use the operation id output by the program to search for the logs and traces associated with the operation. Click on any of the search result to view the end-to-end transaction details. Read more [here](https://learn.microsoft.com/en-us/azure/azure-monitor/app/transaction-search-and-diagnostics?tabs=transaction-search). ### Metrics Running the application once will only generate one set of measurements (for each metrics). Run the application a couple times to generate more sets of measurements. > Note: Make sure not to run the program too frequently. Otherwise, you may get throttled. Please refer to here on how to analyze metrics in [Azure Monitor](https://learn.microsoft.com/en-us/azure/azure-monitor/essentials/analyze-metrics). ### Log Analytics It is also possible to use Log Analytics to query the telemetry items sent by the sample application. Please read more [here](https://learn.microsoft.com/en-us/azure/azure-monitor/logs/log-analytics-tutorial). For example, to create a pie chart to summarize the Handlebars planner status: ```kql dependencies | where name == "Microsoft.SemanticKernel.Planning.Handlebars.HandlebarsPlanner" | extend status = iff(success == True, "Success", "Failure") | summarize count() by status | render piechart ``` Or to create a bar chart to summarize the Handlebars planner status by date: ```kql dependencies | where name == "Microsoft.SemanticKernel.Planning.Handlebars.HandlebarsPlanner" | extend status = iff(success == True, "Success", "Failure"), day = bin(timestamp, 1d) | project day, status | summarize success = countif(status == "Success"), failure = countif(status == "Failure") by day | extend day = format_datetime(day, "MM/dd/yy") | order by day | render barchart ``` Or to see status and performance of each planner run: ```kql dependencies | where name == "Microsoft.SemanticKernel.Planning.Handlebars.HandlebarsPlanner" | extend status = iff(success == True, "Success", "Failure") | project timestamp, id, status, performance = performanceBucket | order by timestamp ``` It is also possible to summarize the total token usage: ```kql customMetrics | where name == "semantic_kernel.connectors.openai.tokens.total" | project value | summarize sum(value) | project Total = sum_value ``` Or track token usage by functions: ```kql customMetrics | where name == "semantic_kernel.function.invocation.token_usage.prompt" and customDimensions has "semantic_kernel.function.name" | project customDimensions, value | extend function = tostring(customDimensions["semantic_kernel.function.name"]) | project function, value | summarize sum(value) by function | render piechart ``` ### Azure Dashboard You can create an Azure Dashboard to visualize the custom telemetry items. You can read more here: [Create a new dashboard](https://learn.microsoft.com/en-us/azure/azure-monitor/app/overview-dashboard#create-a-new-dashboard). ## Aspire Dashboard You can also use the [Aspire dashboard](https://learn.microsoft.com/en-us/dotnet/aspire/fundamentals/dashboard/overview) for local development. ### Steps - Follow this [code sample](https://learn.microsoft.com/en-us/dotnet/aspire/fundamentals/dashboard/overview) to start an Aspire dashboard in a docker container. - Add the package to the project: **`OpenTelemetry.Exporter.OpenTelemetryProtocol`** - Replace all occurrences of ```c# .AddAzureMonitorLogExporter(...) ``` with ```c# .AddOtlpExporter(options => options.Endpoint = new Uri("http://localhost:4317")) ``` - Run the app and you can visual the traces in the Aspire dashboard. ## More information - [Telemetry docs](../../../docs/TELEMETRY.md) - [Planner telemetry improvement ADR](../../../../docs/decisions/0025-planner-telemetry-enhancement.md) - [OTel Semantic Conventions ADR](../../../../docs/decisions/0044-OTel-semantic-convention.md) ================================================ FILE: dotnet/samples/Demos/TelemetryWithAppInsights/RepoUtils/RepoFiles.cs ================================================ // Copyright (c) Microsoft.

Here we have a simple Time Plugin created in C# that can be called from the AI Model to get the current time. ## Semantic Kernel Features Used - [Plugin](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/src/SemanticKernel.Abstractions/Functions/KernelPlugin.cs) - Creating a Plugin from a native C# Booking class to be used by the Kernel to interact with Bookings API. - [Chat Completion Service](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/src/SemanticKernel.Abstractions/AI/ChatCompletion/IChatCompletionService.cs) - Using the Chat Completion Service [OpenAI Connector implementation](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/src/Connectors/Connectors.OpenAI/Services/OpenAIChatCompletionService.cs) to generate responses from the LLM. - [Chat History](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/src/SemanticKernel.Abstractions/AI/ChatCompletion/ChatHistory.cs) Using the Chat History abstraction to create, update and retrieve chat history from Chat Completion Models. - [Auto Function Calling](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/samples/Concepts/ChatCompletion/OpenAI_FunctionCalling.cs) Enables the LLM to have knowledge of current importedUsing the Function Calling feature automatically call the Booking Plugin from the LLM. ## Prerequisites - [.NET 10](https://dotnet.microsoft.com/download/dotnet/10.0). ### Function Calling Enabled Models This sample uses function calling capable models and has been tested with the following models: | Model type | Model name/id | Model version | Supported | | --------------- | ------------------------- | ------------------: | --------- | | Chat Completion | gpt-3.5-turbo | 0125 | ✅ | | Chat Completion | gpt-3.5-turbo-1106 | 1106 | ✅ | | Chat Completion | gpt-3.5-turbo-0613 | 0613 | ✅ | | Chat Completion | gpt-3.5-turbo-0301 | 0301 | ❌ | | Chat Completion | gpt-3.5-turbo-16k | 0613 | ✅ | | Chat Completion | gpt-4 | 0613 | ✅ | | Chat Completion | gpt-4-0613 | 0613 | ✅ | | Chat Completion | gpt-4-0314 | 0314 | ❌ | | Chat Completion | gpt-4-turbo | 2024-04-09 | ✅ | | Chat Completion | gpt-4-turbo-2024-04-09 | 2024-04-09 | ✅ | | Chat Completion | gpt-4-turbo-preview | 0125-preview | ✅ | | Chat Completion | gpt-4-0125-preview | 0125-preview | ✅ | | Chat Completion | gpt-4-vision-preview | 1106-vision-preview | ✅ | | Chat Completion | gpt-4-1106-vision-preview | 1106-vision-preview | ✅ | ℹ️ OpenAI Models older than 0613 version do not support function calling. ## Configuring the sample The sample can be configured by using the command line with .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets) to avoid the risk of leaking secrets into the repository, branches and pull requests. ### Using .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets) ```powershell # OpenAI dotnet user-secrets set "OpenAI:ChatModelId" "gpt-3.5-turbo" dotnet user-secrets set "OpenAI:ApiKey" "... your api key ... " ``` ## Running the sample After configuring the sample, to build and run the console application just hit `F5`. To build and run the console application from the terminal use the following commands: ```powershell dotnet build dotnet run ``` ### Example of a conversation Ask questions to use the Time Plugin such as: - What time is it? **User** > What time is it ? **Assistant** > The current time is Sun, 12 May 2024 15:53:54 GMT. ================================================ FILE: dotnet/samples/Demos/TimePlugin/TimePlugin.csproj ================================================  Exe net10.0 enable enable 5ee045b0-aea3-4f08-8d31-32d1a6f8fed0 $(NoWarn);SKEXP0001 ================================================ FILE: dotnet/samples/Demos/VectorStoreRAG/DataLoader.cs ================================================ // Copyright (c) Microsoft.

You can choose your preferred vector store by setting the `Rag:VectorStoreType` configuration setting in the `appsettings.json` file to one of the following values: 1. AzureAISearch 1. CosmosMongoDB 1. CosmosNoSql 1. InMemory 1. Qdrant 1. Redis 1. Weaviate 1. You can choose your preferred AI Chat service by settings the `Rag:AIChatService` configuration setting in the `appsettings.json` file to one of the following values: 1. AzureOpenAI 1. OpenAI 1. You can choose your preferred AI Embedding service by settings the `Rag:AIEmbeddingService` configuration setting in the `appsettings.json` file to one of the following values: 1. AzureOpenAIEmbeddings 1. OpenAIEmbeddings 1. You can choose whether to load data into the vector store by setting the `Rag:BuildCollection` configuration setting in the `appsettings.json` file to `true`. If you set this to `false`, the sample will assume that data was already loaded previously and it will go straight into the chat experience. 1. You can choose the name of the collection to use by setting the `Rag:CollectionName` configuration setting in the `appsettings.json` file. 1. You can choose the pdf file to load into the vector store by setting the `Rag:PdfFilePaths` array in the `appsettings.json` file. 1. You can choose the number of records to process per batch when loading data into the vector store by setting the `Rag:DataLoadingBatchSize` configuration setting in the `appsettings.json` file. 1. You can choose the number of milliseconds to wait between batches when loading data into the vector store by setting the `Rag:DataLoadingBetweenBatchDelayInMilliseconds` configuration setting in the `appsettings.json` file. ## Dependency Setup To run this sample, you need to setup your source data, setup your vector store and AI services, and setup secrets for these. ### Source PDF File You will need to supply some source pdf files to load into the vector store. Once you have a file ready, update the `PdfFilePaths` array in the `appsettings.json` file with the path to the file. ```json { "Rag": { "PdfFilePaths": [ "sourcedocument.pdf" ], } } ``` Why not try the semantic kernel documentation as your input. You can download it as a PDF from the https://learn.microsoft.com/en-us/semantic-kernel/overview/ page. See the Download PDF button at the bottom of the page. ### Azure OpenAI Chat Completion For Azure OpenAI Chat Completion, you need to add the following secrets: ```cli dotnet user-secrets set "AIServices:AzureOpenAI:Endpoint" "https://.openai.azure.com" dotnet user-secrets set "AIServices:AzureOpenAI:ChatDeploymentName" "" ``` Note that the code doesn't use an API Key to communicate with Azure OpenAI, but rather an `AzureCliCredential` so no api key secret is required. ### OpenAI Chat Completion For OpenAI Chat Completion, you need to add the following secrets: ```cli dotnet user-secrets set "AIServices:OpenAI:ModelId" "" dotnet user-secrets set "AIServices:OpenAI:ApiKey" "" ``` Optionally, you can also provide an Org Id ```cli dotnet user-secrets set "AIServices:OpenAI:OrgId" "" ``` ### Azure OpenAI Embeddings For Azure OpenAI Embeddings, you need to add the following secrets: ```cli dotnet user-secrets set "AIServices:AzureOpenAIEmbeddings:Endpoint" "https://.openai.azure.com" dotnet user-secrets set "AIServices:AzureOpenAIEmbeddings:DeploymentName" "" ``` Note that the code doesn't use an API Key to communicate with Azure OpenAI, but rather an `AzureCliCredential` so no api key secret is required. ### OpenAI Embeddings For OpenAI Embeddings, you need to add the following secrets: ```cli dotnet user-secrets set "AIServices:OpenAIEmbeddings:ModelId" "" dotnet user-secrets set "AIServices:OpenAIEmbeddings:ApiKey" "" ``` Optionally, you can also provide an Org Id ```cli dotnet user-secrets set "AIServices:OpenAIEmbeddings:OrgId" "" ``` ### Azure AI Search If you want to use Azure AI Search as your vector store, you will need to create an instance of Azure AI Search and add the following secrets here: ```cli dotnet user-secrets set "VectorStores:AzureAISearch:Endpoint" "https://.search.windows.net" dotnet user-secrets set "VectorStores:AzureAISearch:ApiKey" "" ``` ### Azure CosmosDB MongoDB If you want to use Azure CosmosDB MongoDB as your vector store, you will need to create an instance of Azure CosmosDB MongoDB and add the following secrets here: ```cli dotnet user-secrets set "VectorStores:CosmosMongoDB:ConnectionString" "" dotnet user-secrets set "VectorStores:CosmosMongoDB:DatabaseName" "" ``` ### Azure CosmosDB NoSQL If you want to use Azure CosmosDB NoSQL as your vector store, you will need to create an instance of Azure CosmosDB NoSQL and add the following secrets here: ```cli dotnet user-secrets set "VectorStores:CosmosNoSql:ConnectionString" "" dotnet user-secrets set "VectorStores:CosmosNoSql:DatabaseName" "" ``` ### Qdrant If you want to use Qdrant as your vector store, you will need to have an instance of Qdrant available. You can use the following command to start a Qdrant instance in docker, and this will work with the default configured settings: ```cli docker run -d --name qdrant -p 6333:6333 -p 6334:6334 qdrant/qdrant:latest ``` If you want to use a different instance of Qdrant, you can update the appsettings.json file or add the following secrets to reconfigure: ```cli dotnet user-secrets set "VectorStores:Qdrant:Host" "" dotnet user-secrets set "VectorStores:Qdrant:Port" "6334" dotnet user-secrets set "VectorStores:Qdrant:Https" "true" dotnet user-secrets set "VectorStores:Qdrant:ApiKey" "" ``` ### Redis If you want to use Redis as your vector store, you will need to have an instance of Redis available.

It captures audio from the microphone, processes it through a pipeline, and plays back the AI-generated responses: Microphone → VAD → STT → Chat (Semantic Kernel) → TTS → Speaker ## Purpose This is not a complete application, but a **starting point** that shows how an audio pipeline can be built using Semantic Kernel and the .NET DataFlow library. It’s intended to help you understand how to structure audio processing with SK, rather than provide a production-ready chat app. ## Voice Activity Detection This demo uses **WebRTC VAD** to detect when the user starts and stops speaking. Other model-based approaches can also be used, such as **[Silero VAD](https://github.com/snakers4/silero-vad/tree/master/examples/csharp)**, which may provide higher accuracy. ## Known Limitations - **Latency** This demo processes audio in discrete steps (non-streaming). Response times are therefore large, sometimes over 20 seconds. To reduce latency, you should use **streaming STT and TTS services** (see below). - **OpenAI Free Tier Rate Limits** Very high latencies can also be caused by OpenAI’s rate limits, especially on free-tier accounts. See the OpenAI [rate limits documentation](https://platform.openai.com/docs/guides/rate-limits) for more details. - **Latency Resources** For more on latency in voice AI pipelines, see this resource: [Latency in LLM Voice Pipelines](https://voiceaiandvoiceagents.com/#latency-llm). ## Suggested Streaming Services To reduce latency in real-world scenarios, you can integrate with streaming speech services such as: - **Speech-to-Text (STT)** - [OpenAI Realtime API (Whisper streaming)](https://platform.openai.com/docs/guides/realtime) - [Azure Cognitive Services Speech-to-Text](https://learn.microsoft.com/azure/cognitive-services/speech-service/speech-to-text) - [Deepgram Streaming STT](https://developers.deepgram.com/docs/streaming) - [AssemblyAI Streaming STT](https://www.assemblyai.com/docs/real-time-speech-recognition) - **Text-to-Speech (TTS)** - [OpenAI Realtime API (TTS streaming)](https://platform.openai.com/docs/guides/realtime) - [Azure Cognitive Services Text-to-Speech](https://learn.microsoft.com/azure/cognitive-services/speech-service/text-to-speech) - [Amazon Polly Neural TTS](https://docs.aws.amazon.com/polly/latest/dg/what-is.html) ## How to Run 1. Store your API key securely with [.NET user-secrets](https://learn.microsoft.com/aspnet/core/security/app-secrets): dotnet user-secrets set "OpenAI:ApiKey" "your-openai-api-key" 2. Build and run the sample: dotnet run --project samples/Demos/VoiceChat 3. Speak into your microphone and listen for the AI response through your speakers. ================================================ FILE: dotnet/samples/Demos/VoiceChat/Services/AudioPlaybackService.cs ================================================ // Copyright (c) Microsoft.

You need to have an AWS account and [access to the foundation models](https://docs.aws.amazon.com/bedrock/latest/userguide/model-access-permissions.html) 2. [AWS CLI installed](https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html) and [configured](https://boto3.amazonaws.com/v1/documentation/api/latest/guide/quickstart.html#configuration) ## Before running the samples You need to set up some user secrets to run the samples. ### `BedrockAgent:AgentResourceRoleArn` On your AWS console, go to the IAM service and go to **Roles**. Find the role you want to use and click on it. You will find the ARN in the summary section. ``` dotnet user-secrets set "BedrockAgent:AgentResourceRoleArn" "arn:aws:iam::...:role/..." ``` ### `BedrockAgent:FoundationModel` You need to make sure you have permission to access the foundation model. You can find the model ID in the [AWS documentation](https://docs.aws.amazon.com/bedrock/latest/userguide/models-supported.html). To see the models you have access to, find the policy attached to your role you should see a list of models you have access to under the `Resource` section. ``` dotnet user-secrets set "BedrockAgent:FoundationModel" "..." ``` ### How to add the `bedrock:InvokeModelWithResponseStream` action to an IAM policy 1. Open the [IAM console](https://console.aws.amazon.com/iam/). 2. On the left navigation pane, choose `Roles` under `Access management`. 3. Find the role you want to edit and click on it. 4. Under the `Permissions policies` tab, click on the policy you want to edit. 5. Under the `Permissions defined in this policy` section, click on the service. You should see **Bedrock** if you already have access to the Bedrock agent service. 6. Click on the service, and then click `Edit`. 7. On the right, you will be able to add an action. Find the service and search for `InvokeModelWithResponseStream`. 8. Check the box next to the action and then scroll all the way down and click `Next`. 9.

To Reproduce Add a filter for the column marked [VectorStoreRecordKey]. Since that same column exists in both the vec_TestTable and TestTable, the data for both columns cannot be returned. Expected behavior The query should explicitly list the vec_TestTable column names to retrieve and should omit the [VectorStoreRecordKey] column since it will be included in the primary TestTable columns.

You can also run specific examples via the command-line by using test filters (`dotnet test --filter`). Type `dotnet test --help` at the command line for more details. Example: ``` dotnet test --filter Step3_Chat ``` ## Configuring Secrets Each example requires secrets / credentials to access OpenAI or Azure OpenAI. We suggest using .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets) to avoid the risk of leaking secrets into the repository, branches and pull requests. You can also use environment variables if you prefer. To set your secrets with .NET Secret Manager: 1. Navigate the console to the project folder: ``` cd dotnet/samples/GettingStartedWithAgents ``` 2. Examine existing secret definitions: ``` dotnet user-secrets list ``` 3. If needed, perform first time initialization: ``` dotnet user-secrets init ``` 4. Define secrets for either Open AI: ``` dotnet user-secrets set "OpenAI:ChatModelId" "..." dotnet user-secrets set "OpenAI:ApiKey" "..." ``` 5. Or Azure OpenAI: ``` dotnet user-secrets set "AzureOpenAI:ChatDeploymentName" "gpt-4o" dotnet user-secrets set "AzureOpenAI:Endpoint" "https://... .openai.azure.com/" dotnet user-secrets set "AzureOpenAI:ApiKey" "..." ``` 6. Or Azure AI: ``` dotnet user-secrets set "AzureAI:Endpoint" "..." dotnet user-secrets set "AzureAI:ChatModelId" "gpt-4o" ``` 7. Or Bedrock: ``` dotnet user-secrets set "BedrockAgent:AgentResourceRoleArn" "arn:aws:iam::...:role/..." dotnet user-secrets set "BedrockAgent:FoundationModel" "..." ``` > NOTE: Azure secrets will take precedence, if both Open AI and Azure OpenAI secrets are defined, unless `ForceOpenAI` is set: ``` protected override bool ForceOpenAI => true; ``` ================================================ FILE: dotnet/samples/GettingStartedWithAgents/Resources/AutoInvokeTools.yaml ================================================ name: ToolAgent template_format: semantic-kernel description: An agent that is configured to auto-invoke plugins. execution_settings: default: function_choice_behavior: type: auto ================================================ FILE: dotnet/samples/GettingStartedWithAgents/Resources/GenerateStory.yaml ================================================ name: GenerateStory template: | Tell a story about {{$topic}} that is {{$length}} sentences long. template_format: semantic-kernel description: A function that generates a story about a topic. input_variables: - name: topic description: The topic of the story. is_required: true - name: length description: The number of sentences in the story. is_required: true output_variable: description: The generated story. execution_settings: default: temperature: 0.6 ================================================ FILE: dotnet/samples/GettingStartedWithAgents/Resources/Hamlet_full_play_summary.txt ================================================ On a dark winter night, a ghost walks the ramparts of Elsinore Castle in Denmark. Discovered first by a pair of watchmen, then by the scholar Horatio, the ghost resembles the recently deceased King Hamlet, whose brother Claudius has inherited the throne and married the king’s widow, Queen Gertrude. When Horatio and the watchmen bring Prince Hamlet, the son of Gertrude and the dead king, to see the ghost, it speaks to him, declaring ominously that it is indeed his father’s spirit, and that he was murdered by none other than Claudius. Ordering Hamlet to seek revenge on the man who usurped his throne and married his wife, the ghost disappears with the dawn. Prince Hamlet devotes himself to avenging his father’s death, but, because he is contemplative and thoughtful by nature, he delays, entering into a deep melancholy and even apparent madness. Claudius and Gertrude worry about the prince’s erratic behavior and attempt to discover its cause. They employ a pair of Hamlet’s friends, Rosencrantz and Guildenstern, to watch him. When Polonius, the pompous Lord Chamberlain, suggests that Hamlet may be mad with love for his daughter, Ophelia, Claudius agrees to spy on Hamlet in conversation with the girl. But though Hamlet certainly seems mad, he does not seem to love Ophelia: he orders her to enter a nunnery and declares that he wishes to ban marriages. A group of traveling actors comes to Elsinore, and Hamlet seizes upon an idea to test his uncle’s guilt. He will have the players perform a scene closely resembling the sequence by which Hamlet imagines his uncle to have murdered his father, so that if Claudius is guilty, he will surely react. When the moment of the murder arrives in the theater, Claudius leaps up and leaves the room. Hamlet and Horatio agree that this proves his guilt. Hamlet goes to kill Claudius but finds him praying. Since he believes that killing Claudius while in prayer would send Claudius’s soul to heaven, Hamlet considers that it would be an inadequate revenge and decides to wait. Claudius, now frightened of Hamlet’s madness and fearing for his own safety, orders that Hamlet be sent to England at once. Hamlet goes to confront his mother, in whose bedchamber Polonius has hidden behind a tapestry. Hearing a noise from behind the tapestry, Hamlet believes the king is hiding there. He draws his sword and stabs through the fabric, killing Polonius. For this crime, he is immediately dispatched to England with Rosencrantz and Guildenstern. However, Claudius’s plan for Hamlet includes more than banishment, as he has given Rosencrantz and Guildenstern sealed orders for the King of England demanding that Hamlet be put to death. In the aftermath of her father’s death, Ophelia goes mad with grief and drowns in the river. Polonius’s son, Laertes, who has been staying in France, returns to Denmark in a rage. Claudius convinces him that Hamlet is to blame for his father’s and sister’s deaths. When Horatio and the king receive letters from Hamlet indicating that the prince has returned to Denmark after pirates attacked his ship en route to England, Claudius concocts a plan to use Laertes’ desire for revenge to secure Hamlet’s death. Laertes will fence with Hamlet in innocent sport, but Claudius will poison Laertes’ blade so that if he draws blood, Hamlet will die. As a backup plan, the king decides to poison a goblet, which he will give Hamlet to drink should Hamlet score the first or second hits of the match. Hamlet returns to the vicinity of Elsinore just as Ophelia’s funeral is taking place. Stricken with grief, he attacks Laertes and declares that he had in fact always loved Ophelia. Back at the castle, he tells Horatio that he believes one must be prepared to die, since death can come at any moment. A foolish courtier named Osric arrives on Claudius’s orders to arrange the fencing match between Hamlet and Laertes. The sword-fighting begins. Hamlet scores the first hit, but declines to drink from the king’s proffered goblet. Instead, Gertrude takes a drink from it and is swiftly killed by the poison. Laertes succeeds in wounding Hamlet, though Hamlet does not die of the poison immediately. First, Laertes is cut by his own sword’s blade, and, after revealing to Hamlet that Claudius is responsible for the queen’s death, he dies from the blade’s poison. Hamlet then stabs Claudius through with the poisoned sword and forces him to drink down the rest of the poisoned wine. Claudius dies, and Hamlet dies immediately after achieving his revenge. At this moment, a Norwegian prince named Fortinbras, who has led an army to Denmark and attacked Poland earlier in the play, enters with ambassadors from England, who report that Rosencrantz and Guildenstern are dead. Fortinbras is stunned by the gruesome sight of the entire royal family lying sprawled on the floor dead. He moves to take power of the kingdom. Horatio, fulfilling Hamlet’s last request, tells him Hamlet’s tragic story. Fortinbras orders that Hamlet be carried away in a manner befitting a fallen soldier. ================================================ FILE: dotnet/samples/GettingStartedWithAgents/Resources/countries.json ================================================ { "openapi": "3.1.0", "info": { "title": "RestCountries.NET API", "description": "Web API version 3.1 for managing country items, based on previous implementations from restcountries.eu and restcountries.com.", "version": "v3.1" }, "servers": [ { "url": "https://restcountries.net" } ], "auth": [], "paths": { "/v3.1/currency": { "get": { "description": "Search by currency.", "operationId": "LookupCountryByCurrency", "parameters": [ { "name": "currency", "in": "query", "description": "The currency to search for.", "required": true, "schema": { "type": "string" } } ], "responses": { "200": { "description": "Success", "content": { "text/plain": { "schema": { "type": "string" } } } } } } } }, "components": { "schemes": {} } } ================================================ FILE: dotnet/samples/GettingStartedWithAgents/Resources/weather.json ================================================ { "openapi": "3.1.0", "info": { "title": "get weather data", "description": "Retrieves current weather data for a location based on wttr.in.", "version": "v1.0.0" }, "servers": [ { "url": "https://wttr.in" } ], "auth": [], "paths": { "/{location}": { "get": { "description": "Get weather information for a specific location", "operationId": "GetCurrentWeather", "parameters": [ { "name": "location", "in": "path", "description": "City or location to retrieve the weather for", "required": true, "schema": { "type": "string" } }, { "name": "format", "in": "query", "description": "Always use j1 value for this parameter", "required": true, "schema": { "type": "string", "default": "j1" } } ], "responses": { "200": { "description": "Successful response", "content": { "text/plain": { "schema": { "type": "string" } } } }, "404": { "description": "Location not found" } }, "deprecated": false } } }, "components": { "schemes": {} } } ================================================ FILE: dotnet/samples/GettingStartedWithAgents/Step01_Agent.cs ================================================ // Copyright (c) Microsoft.

In addition, the sample introduces the concept of using smaller process as steps to maintain the main process readable and manageble for future improvements and unit testing. Also introduces the use of SK Event Subscribers. A process for opening an account for this sample has the following steps: - Fill New User Account Application Form - Verify Applicant Credit Score - Apply Fraud Detection Analysis to the Application Form - Create New Entry in Core System Records - Add new account to Marketing Records - CRM Record Creation - Mail user a user a notification about: - Failure to open a new account due to Credit Score Check - Failure to open a new account due to Fraud Detection Alert - Welcome package including new account details A SK process that only connects the steps listed above as is (no use of subprocesses as steps) for opening an account look like this: #### Step02a_AccountOpening ```mermaid flowchart LR User(User) -->|Provides user details| FillForm(Fill New

When there are no ingredients left, it emits the `Out of Stock Event`. - The `Cut Food Step` is now a stateful component which has a `Knife Sharpness State` that tracks the Knife Sharpness. - As the `Slice Food` and `Chop Food` Functions get invoked, the Knife Sharpness deteriorates. - The `Cut Food Step` has an additional input function `Sharpen Knife Function`. - The new `Sharpen Knife Function` sharpens the knife and increases the Knife Sharpness - Knife Sharpness State. - From time to time, the `Cut Food Step`'s functions `SliceFood` and `ChopFood` will fail and emit a `Knife Needs Sharpening Event` that then triggers the `Sharpen Knife Function`. ###### Potato Fries Preparation With Knife Sharpening and Ingredient Stock Process The following processes is a modification on the process [Potato Fries Preparation](#potato-fries-preparation-process) with the the stateful steps mentioned previously. ``` mermaid flowchart LR PreparePotatoFriesEvent([Prepare Potato

This includes both direct _agent_ interaction as well as making use of _AgentGroupChat_. ```mermaid flowchart RL O --> A O((Start)) A[User] -->|input| B[ManagerAgent] A --> F((Done)) B --> |response|A B --> |delegate| G G --> |response|B subgraph G[GroupChat] direction LR D[Agent1] --> E E[Agent2] --> D end ``` ## Concepts ### Components - **Process:** A sequence of steps designed to achieve a specific goal. These steps are interconnected in such a way that they can communicate by sending and receiving events. The connections between the steps are established during the process creation. - **Steps:** Individual activities within a process, each with defined inputs and outputs, contributing to the overall objective. Existing processes can be utilized as steps within another process. There are two main types of steps: - _Stateless Steps_: These steps do not retain any information between executions. They operate independently without the need to store state data. - _Stateful Steps_: These steps maintain a state that can be persisted, allowing the state to be reused and updated in subsequent runs of the process. The state of these steps can be stored and serialized. In general, both processes and steps are designed to be reusable across different processes. ### Versioning Once stateful steps/processes have been deployed, versioning becomes a crucial aspect to understand. It enables you to tweak and improve processes while maintaining the ability to read step states generated by previous versions of the steps. Stateful processes involve steps that maintain state information. When these processes are updated, it's important to manage versioning effectively to ensure continuity and compatibility with previously saved states. There are two primary scenarios to consider when addressing process state versioning: 1. **Minor SK Process Improvements/Changes:** In this scenario, the root process remains conceptually the same, but with some modifications: - _Step Renaming:_ Some step names may have been changed. - _Step Version Updates:_ New versions of one or more steps used by the root process or any steps in a subprocess may be introduced. **Considerations:** - Ensure backward compatibility by mapping old step names to new step names. - Validate that the new step versions can read and interpret the state data generated by previous versions. **Related Samples:** - `Step03a_FoodPreparation.cs/RunStatefulFriedFishV2ProcessWithLowStockV1StateFromFileAsync` - `Step03a_FoodPreparation.cs/RunStatefulFishSandwichV2ProcessWithLowStockV1StateFromFileAsync` 2. **Major SK Process Improvements/Changes:** This scenario involves significant modifications to the root process, which may include: - _Step Refactoring_: Multiple steps may be refactored and replaced. However, some properties of the replaced steps can be used to set properties of the new steps. - _Custom Mappings:_ Custom equivalent mappings may be required to translate the previous stored state to the current process state. **Considerations:** - Develop a detailed mapping strategy to align old and new process states. - Implement and test custom mappings to ensure data integrity and process continuity. ## Running Examples with Filters Examples may be explored and ran within _Visual Studio_ using _Test Explorer_. You can also run specific examples via the command-line by using test filters (`dotnet test --filter`). Type `dotnet test --help` at the command line for more details. Example: ``` dotnet test --filter Step01_Processes ``` ## Configuring Secrets Each example requires secrets / credentials to access OpenAI or Azure OpenAI. We suggest using .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets) to avoid the risk of leaking secrets into the repository, branches and pull requests. You can also use environment variables if you prefer. To set your secrets with .NET Secret Manager: 1. Navigate the console to the project folder: ``` cd dotnet/samples/GettingStartedWithProcesses ``` 2. Examine existing secret definitions: ``` dotnet user-secrets list ``` 3. If needed, perform first time initialization: ``` dotnet user-secrets init ``` 4. Define secrets for either Open AI: ``` dotnet user-secrets set "OpenAI:ChatModelId" "..." dotnet user-secrets set "OpenAI:ApiKey" "..." ``` 5. Or Azure Open AI: ``` dotnet user-secrets set "AzureOpenAI:DeploymentName" "..." dotnet user-secrets set "AzureOpenAI:ChatDeploymentName" "..." dotnet user-secrets set "AzureOpenAI:Endpoint" "https://... .openai.azure.com/" dotnet user-secrets set "AzureOpenAI:ApiKey" "..." ``` > NOTE: Azure secrets will take precedence, if both Open AI and Azure Open AI secrets are defined, unless `ForceOpenAI` is set: ``` protected override bool ForceOpenAI => true; ``` ================================================ FILE: dotnet/samples/GettingStartedWithProcesses/SharedSteps/DisplayAssistantMessageStep.cs ================================================ // Copyright (c) Microsoft.

The examples can be run as integration tests but their code can also be copied to stand-alone programs. ## Configuring Secrets Most of the examples will require secrets and credentials, to access OpenAI, Azure OpenAI, Bing and other resources. We suggest using .NET [Secret Manager](https://learn.microsoft.com/aspnet/core/security/app-secrets) to avoid the risk of leaking secrets into the repository, branches and pull requests. You can also use environment variables if you prefer. **NOTE** The `Step2_Search_For_RAG.RagWithBingTextSearchUsingFullPagesAsync` sample requires a large context window so we recommend using `gpt-4o` or `gpt-4o-mini` models. To set your secrets with Secret Manager: ``` cd dotnet/samples/Concepts dotnet user-secrets init dotnet user-secrets set "OpenAI:EmbeddingModelId" "..." dotnet user-secrets set "OpenAI:ChatModelId" "..." dotnet user-secrets set "OpenAI:ApiKey" "..." dotnet user-secrets set "Bing:ApiKey" "..." dotnet user-secrets set "Google:SearchEngineId" "..." dotnet user-secrets set "Google:ApiKey" "..." ``` To set your secrets with environment variables, use these names: ``` OpenAI__EmbeddingModelId OpenAI__ChatModelId OpenAI__ApiKey Bing__ApiKey Google__SearchEngineId Google__ApiKey ``` ================================================ FILE: dotnet/samples/GettingStartedWithTextSearch/Step1_Web_Search.cs ================================================ // Copyright (c) Microsoft.

The examples can be run as integration tests but their code can also be copied to stand-alone programs. ## Configuring Secrets Most of the examples will require secrets and credentials, to access OpenAI, Azure OpenAI, Vector Stores and other resources. We suggest using .NET [Secret Manager](https://learn.microsoft.com/aspnet/core/security/app-secrets) to avoid the risk of leaking secrets into the repository, branches and pull requests. You can also use environment variables if you prefer. To set your secrets with Secret Manager: ``` cd dotnet/samples/GettingStartedWithVectorStores dotnet user-secrets init dotnet user-secrets set "AzureOpenAIEmbeddings:DeploymentName" "..." dotnet user-secrets set "AzureOpenAIEmbeddings:Endpoint" "..." dotnet user-secrets set "AzureAISearch:Endpoint" "..." dotnet user-secrets set "AzureAISearch:ApiKey" "..." ``` To set your secrets with environment variables, use these names: ``` AzureOpenAIEmbeddings__DeploymentName AzureOpenAIEmbeddings__Endpoint AzureAISearch__Endpoint AzureAISearch__ApiKey ``` ================================================ FILE: dotnet/samples/GettingStartedWithVectorStores/Step1_Ingest_Data.cs ================================================ // Copyright (c) Microsoft.

He had two richly laden ships then making a voyage upon the seas, in which he had embarked all his wealth, in the hope of making great gains, when the news came that both were lost. Thus from being a rich man he became all at once so very poor that nothing was left to him but one small plot of land; and there he often went in an evening to take his walk, and ease his mind of a little of his trouble. One day, as he was roaming along in a brown study, thinking with no great comfort on what he had been and what he now was, and was like to be, all on a sudden there stood before him a little, rough-looking, black dwarf. ’Prithee, friend, why so sorrowful?’ said he to the merchant; ’what is it you take so deeply to heart?’ ’If you would do me any good I would willingly tell you,’ said the merchant. ’Who knows but I may?’ said the little man: ’tell me what ails you, and perhaps you will find I may be of some use.’ Then the merchant told him how all his wealth was gone to the bottom of the sea, and how he had nothing left but that little plot of land. ’Oh, trouble not yourself about that,’ said the dwarf; ’only undertake to bring me here, twelve years hence, whatever meets you first on your going home, and I will give you as much as you please.’ The merchant thought this was no great thing to ask; that it would most likely be his dog or his cat, or something of that sort, but forgot his little boy Heinel; so he agreed to the bargain, and signed and sealed the bond to do what was asked of him. But as he drew near home, his little boy was so glad to see him that he crept behind him, and laid fast hold of his legs, and looked up in his face and laughed. Then the father started, trembling with fear and horror, and saw what it was that he had bound himself to do; but as no gold was come, he made himself easy by thinking that it was only a joke that the dwarf was playing him, and that, at any rate, when the money came, he should see the bearer, and would not take it in. About a month afterwards he went upstairs into a lumber-room to look for some old iron, that he might sell it and raise a little money; and there, instead of his iron, he saw a large pile of gold lying on the floor. At the sight of this he was overjoyed, and forgetting all about his son, went into trade again, and became a richer merchant than before. Meantime little Heinel grew up, and as the end of the twelve years drew near the merchant began to call to mind his bond, and became very sad and thoughtful; so that care and sorrow were written upon his face. The boy one day asked what was the matter, but his father would not tell for some time; at last, however, he said that he had, without knowing it, sold him for gold to a little, ugly-looking, black dwarf, and that the twelve years were coming round when he must keep his word. Then Heinel said, ’Father, give yourself very little trouble about that; I shall be too much for the little man.’ When the time came, the father and son went out together to the place agreed upon: and the son drew a circle on the ground, and set himself and his father in the middle of it. The little black dwarf soon came, and walked round and round about the circle, but could not find any way to get into it, and he either could not, or dared not, jump over it. At last the boy said to him. ’Have you anything to say to us, my friend, or what do you want?’ Now Heinel had found a friend in a good fairy, that was fond of him, and had told him what to do; for this fairy knew what good luck was in store for him. ’Have you brought me what you said you would?’ said the dwarf to the merchant. The old man held his tongue, but Heinel said again, ’What do you want here?’ The dwarf said, ’I come to talk with your father, not with you.’ ’You have cheated and taken in my father,’ said the son; ’pray give him up his bond at once.’ ’Fair and softly,’ said the little old man; ’right is right; I have paid my money, and your father has had it, and spent it; so be so good as to let me have what I paid it for.’ ’You must have my consent to that first,’ said Heinel, ’so please to step in here, and let us talk it over.’ The old man grinned, and showed his teeth, as if he should have been very glad to get into the circle if he could. Then at last, after a long talk, they came to terms. Heinel agreed that his father must give him up, and that so far the dwarf should have his way: but, on the other hand, the fairy had told Heinel what fortune was in store for him, if he followed his own course; and he did not choose to be given up to his hump-backed friend, who seemed so anxious for his company. So, to make a sort of drawn battle of the matter, it was settled that Heinel should be put into an open boat, that lay on the sea-shore hard by; that the father should push him off with his own hand, and that he should thus be set adrift, and left to the bad or good luck of wind and weather. Then he took leave of his father, and set himself in the boat, but before it got far off a wave struck it, and it fell with one side low in the water, so the merchant thought that poor Heinel was lost, and went home very sorrowful, while the dwarf went his way, thinking that at any rate he had had his revenge. The boat, however, did not sink, for the good fairy took care of her friend, and soon raised the boat up again, and it went safely on. The young man sat safe within, till at length it ran ashore upon an unknown land. As he jumped upon the shore he saw before him a beautiful castle but empty and dreary within, for it was enchanted. ’Here,’ said he to himself, ’must I find the prize the good fairy told me of.’ So he once more searched the whole palace through, till at last he found a white snake, lying coiled up on a cushion in one of the chambers. Now the white snake was an enchanted princess; and she was very glad to see him, and said, ’Are you at last come to set me free? Twelve long years have I waited here for the fairy to bring you hither as she promised, for you alone can save me. This night twelve men will come: their faces will be black, and they will be dressed in chain armour. They will ask what you do here, but give no answer; and let them do what they will–beat, whip, pinch, prick, or torment you–bear all; only speak not a word, and at twelve o’clock they must go away. The second night twelve others will come: and the third night twenty-four, who will even cut off your head; but at the twelfth hour of that night their power is gone, and I shall be free, and will come and bring you the Water of Life, and will wash you with it, and bring you back to life and health.’ And all came to pass as she had said; Heinel bore all, and spoke not a word; and the third night the princess came, and fell on his neck and kissed him. Joy and gladness burst forth throughout the castle, the wedding was celebrated, and he was crowned king of the Golden Mountain. They lived together very happily, and the queen had a son. And thus eight years had passed over their heads, when the king thought of his father; and he began to long to see him once again. But the queen was against his going, and said, ’I know well that misfortunes will come upon us if you go.’ However, he gave her no rest till she agreed. At his going away she gave him a wishing-ring, and said, ’Take this ring, and put it on your finger; whatever you wish it will bring you; only promise never to make use of it to bring me hence to your father’s house.’ Then he said he would do what she asked, and put the ring on his finger, and wished himself near the town where his father lived. Heinel found himself at the gates in a moment; but the guards would not let him go in, because he was so strangely clad. So he went up to a neighbouring hill, where a shepherd dwelt, and borrowed his old frock, and thus passed unknown into the town. When he came to his father’s house, he said he was his son; but the merchant would not believe him, and said he had had but one son, his poor Heinel, who he knew was long since dead: and as he was only dressed like a poor shepherd, he would not even give him anything to eat. The king, however, still vowed that he was his son, and said, ’Is there no mark by which you would know me if I am really your son?’ ’Yes,’ said his mother, ’our Heinel had a mark like a raspberry on his right arm.’ Then he showed them the mark, and they knew that what he had said was true. He next told them how he was king of the Golden Mountain, and was married to a princess, and had a son seven years old. But the merchant said, ’that can never be true; he must be a fine king truly who travels about in a shepherd’s frock!’ At this the son was vexed; and forgetting his word, turned his ring, and wished for his queen and son. In an instant they stood before him; but the queen wept, and said he had broken his word, and bad luck would follow. He did all he could to soothe her, and she at last seemed to be appeased; but she was not so in truth, and was only thinking how she should punish him. One day he took her to walk with him out of the town, and showed her the spot where the boat was set adrift upon the wide waters. Then he sat himself down, and said, ’I am very much tired; sit by me, I will rest my head in your lap, and sleep a while.’ As soon as he had fallen asleep, however, she drew the ring from his finger, and crept softly away, and wished herself and her son at home in their kingdom. And when he awoke he found himself alone, and saw that the ring was gone from his finger. ’I can never go back to my father’s house,’ said he; ’they would say I am a sorcerer: I will journey forth into the world, till I come again to my kingdom.’ So saying he set out and travelled till he came to a hill, where three giants were sharing their father’s goods; and as they saw him pass they cried out and said, ’Little men have sharp wits; he shall part the goods between us.’ Now there was a sword that cut off an enemy’s head whenever the wearer gave the words, ’Heads off!’; a cloak that made the owner invisible, or gave him any form he pleased; and a pair of boots that carried the wearer wherever he wished. Heinel said they must first let him try these wonderful things, then he might know how to set a value upon them. Then they gave him the cloak, and he wished himself a fly, and in a moment he was a fly. ’The cloak is very well,’ said he: ’now give me the sword.’ ’No,’ said they; ’not unless you undertake not to say, “Heads off!” for if you do we are all dead men.’ So they gave it him, charging him to try it on a tree. He next asked for the boots also; and the moment he had all three in his power, he wished himself at the Golden Mountain; and there he was at once. So the giants were left behind with no goods to share or quarrel about. As Heinel came near his castle he heard the sound of merry music; and the people around told him that his queen was about to marry another husband. Then he threw his cloak around him, and passed through the castle hall, and placed himself by the side of the queen, where no one saw him. But when anything to eat was put upon her plate, he took it away and ate it himself; and when a glass of wine was handed to her, he took it and drank it; and thus, though they kept on giving her meat and drink, her plate and cup were always empty. Upon this, fear and remorse came over her, and she went into her chamber alone, and sat there weeping; and he followed her there. ’Alas!’ said she to herself, ’was I not once set free? Why then does this enchantment still seem to bind me?’ ’False and fickle one!’ said he. ’One indeed came who set thee free, and he is now near thee again; but how have you used him? Ought he to have had such treatment from thee?’ Then he went out and sent away the company, and said the wedding was at an end, for that he was come back to the kingdom. But the princes, peers, and great men mocked at him. However, he would enter into no parley with them, but only asked them if they would go in peace or not. Then they turned upon him and tried to seize him; but he drew his sword. ’Heads Off!’ cried he; and with the word the traitors’ heads fell before him, and Heinel was once more king of the Golden Mountain. ================================================ FILE: dotnet/samples/LearnResources/Resources/Grimms-The-Water-of-Life.txt ================================================ The Water of Life By the Grimm Brothers Long before you or I were born, there reigned, in a country a great way off, a king who had three sons. This king once fell very ill–so ill that nobody thought he could live. His sons were very much grieved at their father’s sickness; and as they were walking together very mournfully in the garden of the palace, a little old man met them and asked what was the matter. They told him that their father was very ill, and that they were afraid nothing could save him. ’I know what would,’ said the little old man; ’it is the Water of Life. If he could have a draught of it he would be well again; but it is very hard to get.’ Then the eldest son said, ’I will soon find it’: and he went to the sick king, and begged that he might go in search of the Water of Life, as it was the only thing that could save him. ’No,’ said the king. ’I had rather die than place you in such great danger as you must meet with in your journey.’ But he begged so hard that the king let him go; and the prince thought to himself, ’If I bring my father this water, he will make me sole heir to his kingdom.’ Then he set out: and when he had gone on his way some time he came to a deep valley, overhung with rocks and woods; and as he looked around, he saw standing above him on one of the rocks a little ugly dwarf, with a sugarloaf cap and a scarlet cloak; and the dwarf called to him and said, ’Prince, whither so fast?’ ’What is that to thee, you ugly imp?’ said the prince haughtily, and rode on. But the dwarf was enraged at his behaviour, and laid a fairy spell of ill-luck upon him; so that as he rode on the mountain pass became narrower and narrower, and at last the way was so straitened that he could not go to step forward: and when he thought to have turned his horse round and go back the way he came, he heard a loud laugh ringing round him, and found that the path was closed behind him, so that he was shut in all round. He next tried to get off his horse and make his way on foot, but again the laugh rang in his ears, and he found himself unable to move a step, and thus he was forced to abide spellbound. Meantime the old king was lingering on in daily hope of his son’s return, till at last the second son said, ’Father, I will go in search of the Water of Life.’ For he thought to himself, ’My brother is surely dead, and the kingdom will fall to me if I find the water.’ The king was at first very unwilling to let him go, but at last yielded to his wish. So he set out and followed the same road which his brother had done, and met with the same elf, who stopped him at the same spot in the mountains, saying, as before, ’Prince, prince, whither so fast?’ ’Mind your own affairs, busybody!’ said the prince scornfully, and rode on. But the dwarf put the same spell upon him as he put on his elder brother, and he, too, was at last obliged to take up his abode in the heart of the mountains. Thus it is with proud silly people, who think themselves above everyone else, and are too proud to ask or take advice. When the second prince had thus been gone a long time, the youngest son said he would go and search for the Water of Life, and trusted he should soon be able to make his father well again. So he set out, and the dwarf met him too at the same spot in the valley, among the mountains, and said, ’Prince, whither so fast?’ And the prince said, ’I am going in search of the Water of Life, because my father is ill, and like to die: can you help me? Pray be kind, and aid me if you can!’ ’Do you know where it is to be found?’ asked the dwarf. ’No,’ said the prince, ’I do not. Pray tell me if you know.’ ’Then as you have spoken to me kindly, and are wise enough to seek for advice, I will tell you how and where to go. The water you seek springs from a well in an enchanted castle; and, that you may be able to reach it in safety, I will give you an iron wand and two little loaves of bread; strike the iron door of the castle three times with the wand, and it will open: two hungry lions will be lying down inside gaping for their prey, but if you throw them the bread they will let you pass; then hasten on to the well, and take some of the Water of Life before the clock strikes twelve; for if you tarry longer the door will shut upon you for ever.’ Then the prince thanked his little friend with the scarlet cloak for his friendly aid, and took the wand and the bread, and went travelling on and on, over sea and over land, till he came to his journey’s end, and found everything to be as the dwarf had told him. The door flew open at the third stroke of the wand, and when the lions were quieted he went on through the castle and came at length to a beautiful hall. Around it he saw several knights sitting in a trance; then he pulled off their rings and put them on his own fingers. In another room he saw on a table a sword and a loaf of bread, which he also took. Further on he came to a room where a beautiful young lady sat upon a couch; and she welcomed him joyfully, and said, if he would set her free from the spell that bound her, the kingdom should be his, if he would come back in a year and marry her. Then she told him that the well that held the Water of Life was in the palace gardens; and bade him make haste, and draw what he wanted before the clock struck twelve. He walked on; and as he walked through beautiful gardens he came to a delightful shady spot in which stood a couch; and he thought to himself, as he felt tired, that he would rest himself for a while, and gaze on the lovely scenes around him. So he laid himself down, and sleep fell upon him unawares, so that he did not wake up till the clock was striking a quarter to twelve. Then he sprang from the couch dreadfully frightened, ran to the well, filled a cup that was standing by him full of water, and hastened to get away in time. Just as he was going out of the iron door it struck twelve, and the door fell so quickly upon him that it snapped off a piece of his heel. When he found himself safe, he was overjoyed to think that he had got the Water of Life; and as he was going on his way homewards, he passed by the little dwarf, who, when he saw the sword and the loaf, said, ’You have made a noble prize; with the sword you can at a blow slay whole armies, and the bread will never fail you.’ Then the prince thought to himself, ’I cannot go home to my father without my brothers’; so he said, ’My dear friend, cannot you tell me where my two brothers are, who set out in search of the Water of Life before me, and never came back?’ ’I have shut them up by a charm between two mountains,’ said the dwarf, ’because they were proud and ill-behaved, and scorned to ask advice.’ The prince begged so hard for his brothers, that the dwarf at last set them free, though unwillingly, saying, ’Beware of them, for they have bad hearts.’ Their brother, however, was greatly rejoiced to see them, and told them all that had happened to him; how he had found the Water of Life, and had taken a cup full of it; and how he had set a beautiful princess free from a spell that bound her; and how she had engaged to wait a whole year, and then to marry him, and to give him the kingdom. Then they all three rode on together, and on their way home came to a country that was laid waste by war and a dreadful famine, so that it was feared all must die for want. But the prince gave the king of the land the bread, and all his kingdom ate of it. And he lent the king the wonderful sword, and he slew the enemy’s army with it; and thus the kingdom was once more in peace and plenty. In the same manner he befriended two other countries through which they passed on their way. When they came to the sea, they got into a ship and during their voyage the two eldest said to themselves, ’Our brother has got the water which we could not find, therefore our father will forsake us and give him the kingdom, which is our right’; so they were full of envy and revenge, and agreed together how they could ruin him. Then they waited till he was fast asleep, and poured the Water of Life out of the cup, and took it for themselves, giving him bitter sea-water instead. When they came to their journey’s end, the youngest son brought his cup to the sick king, that he might drink and be healed. Scarcely, however, had he tasted the bitter sea-water when he became worse even than he was before; and then both the elder sons came in, and blamed the youngest for what they had done; and said that he wanted to poison their father, but that they had found the Water of Life, and had brought it with them. He no sooner began to drink of what they brought him, than he felt his sickness leave him, and was as strong and well as in his younger days. Then they went to their brother, and laughed at him, and said, ’Well, brother, you found the Water of Life, did you? You have had the trouble and we shall have the reward. Pray, with all your cleverness, why did not you manage to keep your eyes open? Next year one of us will take away your beautiful princess, if you do not take care. You had better say nothing about this to our father, for he does not believe a word you say; and if you tell tales, you shall lose your life into the bargain: but be quiet, and we will let you off.’ The old king was still very angry with his youngest son, and thought that he really meant to have taken away his life; so he called his court together, and asked what should be done, and all agreed that he ought to be put to death. The prince knew nothing of what was going on, till one day, when the king’s chief huntsmen went a-hunting with him, and they were alone in the wood together, the huntsman looked so sorrowful that the prince said, ’My friend, what is the matter with you?’ ’I cannot and dare not tell you,’ said he. But the prince begged very hard, and said, ’Only tell me what it is, and do not think I shall be angry, for I will forgive you.’ ’Alas!’ said the huntsman; ’the king has ordered me to shoot you.’ The prince started at this, and said, ’Let me live, and I will change dresses with you; you shall take my royal coat to show to my father, and do you give me your shabby one.’ ’With all my heart,’ said the huntsman; ’I am sure I shall be glad to save you, for I could not have shot you.’ Then he took the prince’s coat, and gave him the shabby one, and went away through the wood. Some time after, three grand embassies came to the old king’s court, with rich gifts of gold and precious stones for his youngest son; now all these were sent from the three kings to whom he had lent his sword and loaf of bread, in order to rid them of their enemy and feed their people. This touched the old king’s heart, and he thought his son might still be guiltless, and said to his court, ’O that my son were still alive! how it grieves me that I had him killed!’ ’He is still alive,’ said the huntsman; ’and I am glad that I had pity on him, but let him go in peace, and brought home his royal coat.’ At this the king was overwhelmed with joy, and made it known throughout all his kingdom, that if his son would come back to his court he would forgive him. Meanwhile the princess was eagerly waiting till her deliverer should come back; and had a road made leading up to her palace all of shining gold; and told her courtiers that whoever came on horseback, and rode straight up to the gate upon it, was her true lover; and that they must let him in: but whoever rode on one side of it, they must be sure was not the right one; and that they must send him away at once. The time soon came, when the eldest brother thought that he would make haste to go to the princess, and say that he was the one who had set her free, and that he should have her for his wife, and the kingdom with her. As he came before the palace and saw the golden road, he stopped to look at it, and he thought to himself, ’It is a pity to ride upon this beautiful road’; so he turned aside and rode on the right-hand side of it. But when he came to the gate, the guards, who had seen the road he took, said to him, he could not be what he said he was, and must go about his business. The second prince set out soon afterwards on the same errand; and when he came to the golden road, and his horse had set one foot upon it, he stopped to look at it, and thought it very beautiful, and said to himself, ’What a pity it is that anything should tread here!’ Then he too turned aside and rode on the left side of it. But when he came to the gate the guards said he was not the true prince, and that he too must go away about his business; and away he went. Now when the full year was come round, the third brother left the forest in which he had lain hid for fear of his father’s anger, and set out in search of his betrothed bride. So he journeyed on, thinking of her all the way, and rode so quickly that he did not even see what the road was made of, but went with his horse straight over it; and as he came to the gate it flew open, and the princess welcomed him with joy, and said he was her deliverer, and should now be her husband and lord of the kingdom. When the first joy at their meeting was over, the princess told him she had heard of his father having forgiven him, and of his wish to have him home again: so, before his wedding with the princess, he went to visit his father, taking her with him. Then he told him everything; how his brothers had cheated and robbed him, and yet that he had borne all those wrongs for the love of his father. And the old king was very angry, and wanted to punish his wicked sons; but they made their escape, and got into a ship and sailed away over the wide sea, and where they went to nobody knew and nobody cared. And now the old king gathered together his court, and asked all his kingdom to come and celebrate the wedding of his son and the princess. And young and old, noble and squire, gentle and simple, came at once on the summons; and among the rest came the friendly dwarf, with the sugarloaf hat, and a new scarlet cloak. And the wedding was held, and the merry bells run. And all the good people they danced and they sung, And feasted and frolick’d I can’t tell how long. ================================================ FILE: dotnet/samples/LearnResources/Resources/Grimms-The-White-Snake.txt ================================================ The White Snake By the Grimm Brothers A long time ago there lived a king who was famed for his wisdom through all the land. Nothing was hidden from him, and it seemed as if news of the most secret things was brought to him through the air. But he had a strange custom; every day after dinner, when the table was cleared, and no one else was present, a trusty servant had to bring him one more dish. It was covered, however, and even the servant did not know what was in it, neither did anyone know, for the king never took off the cover to eat of it until he was quite alone. This had gone on for a long time, when one day the servant, who took away the dish, was overcome with such curiosity that he could not help carrying the dish into his room. When he had carefully locked the door, he lifted up the cover, and saw a white snake lying on the dish. But when he saw it he could not deny himself the pleasure of tasting it, so he cut of a little bit and put it into his mouth. No sooner had it touched his tongue than he heard a strange whispering of little voices outside his window. He went and listened, and then noticed that it was the sparrows who were chattering together, and telling one another of all kinds of things which they had seen in the fields and woods. Eating the snake had given him power of understanding the language of animals. Now it so happened that on this very day the queen lost her most beautiful ring, and suspicion of having stolen it fell upon this trusty servant, who was allowed to go everywhere. The king ordered the man to be brought before him, and threatened with angry words that unless he could before the morrow point out the thief, he himself should be looked upon as guilty and executed. In vain he declared his innocence; he was dismissed with no better answer. In his trouble and fear he went down into the courtyard and took thought how to help himself out of his trouble. Now some ducks were sitting together quietly by a brook and taking their rest; and, whilst they were making their feathers smooth with their bills, they were having a confidential conversation together. The servant stood by and listened. They were telling one another of all the places where they had been waddling about all the morning, and what good food they had found; and one said in a pitiful tone: ’Something lies heavy on my stomach; as I was eating in haste I swallowed a ring which lay under the queen’s window.’ The servant at once seized her by the neck, carried her to the kitchen, and said to the cook: ’Here is a fine duck; pray, kill her.’ ’Yes,’ said the cook, and weighed her in his hand; ’she has spared no trouble to fatten herself, and has been waiting to be roasted long enough.’ So he cut off her head, and as she was being dressed for the spit, the queen’s ring was found inside her. The servant could now easily prove his innocence; and the king, to make amends for the wrong, allowed him to ask a favour, and promised him the best place in the court that he could wish for. The servant refused everything, and only asked for a horse and some money for travelling, as he had a mind to see the world and go about a little. When his request was granted he set out on his way, and one day came to a pond, where he saw three fishes caught in the reeds and gasping for water. Now, though it is said that fishes are dumb, he heard them lamenting that they must perish so miserably, and, as he had a kind heart, he got off his horse and put the three prisoners back into the water. They leapt with delight, put out their heads, and cried to him: ’We will remember you and repay you for saving us!’ He rode on, and after a while it seemed to him that he heard a voice in the sand at his feet. He listened, and heard an ant-king complain: ’Why cannot folks, with their clumsy beasts, keep off our bodies? That stupid horse, with his heavy hoofs, has been treading down my people without mercy!’ So he turned on to a side path and the ant-king cried out to him: ’We will remember you–one good turn deserves another!’ The path led him into a wood, and there he saw two old ravens standing by their nest, and throwing out their young ones. ’Out with you, you idle, good-for-nothing creatures!’ cried they; ’we cannot find food for you any longer; you are big enough, and can provide for yourselves.’ But the poor young ravens lay upon the ground, flapping their wings, and crying: ’Oh, what helpless chicks we are! We must shift for ourselves, and yet we cannot fly! What can we do, but lie here and starve?’ So the good young fellow alighted and killed his horse with his sword, and gave it to them for food. Then they came hopping up to it, satisfied their hunger, and cried: ’We will remember you–one good turn deserves another!’ And now he had to use his own legs, and when he had walked a long way, he came to a large city. There was a great noise and crowd in the streets, and a man rode up on horseback, crying aloud: ’The king’s daughter wants a husband; but whoever seeks her hand must perform a hard task, and if he does not succeed he will forfeit his life.’ Many had already made the attempt, but in vain; nevertheless when the youth saw the king’s daughter he was so overcome by her great beauty that he forgot all danger, went before the king, and declared himself a suitor. So he was led out to the sea, and a gold ring was thrown into it, before his eyes; then the king ordered him to fetch this ring up from the bottom of the sea, and added: ’If you come up again without it you will be thrown in again and again until you perish amid the waves.’ All the people grieved for the handsome youth; then they went away, leaving him alone by the sea. He stood on the shore and considered what he should do, when suddenly he saw three fishes come swimming towards him, and they were the very fishes whose lives he had saved. The one in the middle held a mussel in its mouth, which it laid on the shore at the youth’s feet, and when he had taken it up and opened it, there lay the gold ring in the shell. Full of joy he took it to the king and expected that he would grant him the promised reward. But when the proud princess perceived that he was not her equal in birth, she scorned him, and required him first to perform another task. She went down into the garden and strewed with her own hands ten sacksful of millet-seed on the grass; then she said: ’Tomorrow morning before sunrise these must be picked up, and not a single grain be wanting.’ The youth sat down in the garden and considered how it might be possible to perform this task, but he could think of nothing, and there he sat sorrowfully awaiting the break of day, when he should be led to death. But as soon as the first rays of the sun shone into the garden he saw all the ten sacks standing side by side, quite full, and not a single grain was missing. The ant-king had come in the night with thousands and thousands of ants, and the grateful creatures had by great industry picked up all the millet-seed and gathered them into the sacks. Presently the king’s daughter herself came down into the garden, and was amazed to see that the young man had done the task she had given him. But she could not yet conquer her proud heart, and said: ’Although he has performed both the tasks, he shall not be my husband until he had brought me an apple from the Tree of Life.’ The youth did not know where the Tree of Life stood, but he set out, and would have gone on for ever, as long as his legs would carry him, though he had no hope of finding it. After he had wandered through three kingdoms, he came one evening to a wood, and lay down under a tree to sleep. But he heard a rustling in the branches, and a golden apple fell into his hand. At the same time three ravens flew down to him, perched themselves upon his knee, and said: ’We are the three young ravens whom you saved from starving; when we had grown big, and heard that you were seeking the Golden Apple, we flew over the sea to the end of the world, where the Tree of Life stands, and have brought you the apple.’ The youth, full of joy, set out homewards, and took the Golden Apple to the king’s beautiful daughter, who had now no more excuses left to make. They cut the Apple of Life in two and ate it together; and then her heart became full of love for him, and they lived in undisturbed happiness to a great age.

================================================ FILE: dotnet/samples/LearnResources/Resources/WomensSuffrage.txt ================================================ Women's suffrage is when women got the right to vote. A long time ago, only men could vote and make decisions. This was not fair because women should have the same rights as men. Women wanted to vote too, so they started asking for it. It took a long time, and they had to work very hard to make people listen to them. Many men did not think women should vote, and this made it very hard for the women. The women who fought for voting were called suffragets. They did many things to show they wanted the right to vote. Some gave speeches, others made signs and marched in the streets. Some even went to jail because they refused to stop fighting for what they believed was right. It was scary for some of the women, but they knew how important it was to keep trying. They wanted to change the world so that it was more fair for everyone. One of the most important suffragets was Susan B. Anthony. She worked very hard to help women get the right to vote. She gave speeches and wrote letters to the goverment to make them change the laws. Susan never gave up, even when people said mean things to her. Another important person was Elizabeth Cady Stanton. She also helped fight for women's rights and was friends with Susan B. Anthony. Together, they made a great team and helped make big changes. Finally, in 1920, the 19th amendment was passed in the United States. This law gave women the right to vote. It was a huge victory for the suffragets, and they were very happy. Many women went to vote for the first time, and it felt like they were finally equal with men. It took many years and a lot of hard work, but the women never gave up. They kept fighting until they won. Women's suffrage is very important because it shows that if you work hard and believe in something, you can make a change. The women who fought for the right to vote showed bravery and strengh, and they helped make the world a better place. Today, women can vote because of them, and it's important to remember their hard work. We should always stand up for what is right, just like the suffragets did. ================================================ FILE: dotnet/samples/LearnResources/Resources/getIntent.prompt.yaml ================================================ name: getIntent description: Gets the intent of the user. template: | Instructions: What is the intent of this request?

The integration of Bedrock Agents with Semantic Kernel allows users to register kernel functions as tools in Bedrock Agents. ## Enable code interpretation Bedrock Agents can write and execute code via a feature known as [code interpretation](https://docs.aws.amazon.com/bedrock/latest/userguide/agents-code-interpretation.html) similar to what OpenAI also offers. ## Enable user input Bedrock Agents can [request user input](https://docs.aws.amazon.com/bedrock/latest/userguide/agents-user-input.html) in case of missing information to invoke a tool. When this is enabled, the agent will prompt the user for the missing information. When this is disabled, the agent will guess the missing information. ## Knowledge base Bedrock Agents can leverage data saved on AWS to perform RAG tasks, this is referred to as the [knowledge base](https://docs.aws.amazon.com/bedrock/latest/userguide/agents-kb-add.html) in AWS. ## Multi-agent Bedrock Agents support [multi-agent workflows](https://docs.aws.amazon.com/bedrock/latest/userguide/agents-multi-agent-collaboration.html) for more complex tasks. However, it employs a different pattern than what we have in Semantic Kernel, thus this is not supported in the current integration. ================================================ FILE: dotnet/src/Agents/Copilot/Agents.CopilotStudio.csproj ================================================  Microsoft.SemanticKernel.Agents.CopilotStudio Microsoft.SemanticKernel.Agents.CopilotStudio net10.0;net8.0;netstandard2.0 $(NoWarn);CA1724;IDE1006;SKEXP0110 false alpha Semantic Kernel Agents - Copilot Studio Defines a concrete Agent based on the Bedrock Agent Service. ================================================ FILE: dotnet/src/Agents/Copilot/CopilotStudioAgent.ClientFactory.cs ================================================ // Copyright (c) Microsoft.

This agent allows you to interact with Microsoft Copilot Studio agents through programmatic APIs. > ℹ️ **Note:** Knowledge sources must be configured **within** Microsoft Copilot Studio first. Streaming responses are **not currently supported**. --- ## 🔧 Prerequisites 2. Install `Microsoft.SemanticKernel.Agents.CopilotStudio` package: ```bash dotnet add package Microsoft.SemanticKernel.Agents.CopilotStudio --prerelease ``` 3. An agent created in **Microsoft Copilot Studio** 4. Ability to create an application identity in Azure for a **Public Client/Native App Registration**, or access to an existing app registration with the `CopilotStudio.Copilots.Invoke` API permission assigned. ## Create a Copilot Agent in Copilot Studio 1. Go to [Microsoft Copilot Studio](https://copilotstudio.microsoft.com). 2. Create a new **Agent**. 3. Publish your newly created Agent. 4. In Copilot Studio, navigate to: `Settings` → `Advanced` → `Metadata` Save the following values: - `Schema Name` (maps to `agent_identifier`) - `Environment ID` ## Create an Application Registration in Entra ID – User Interactive Login > This step requires permissions to create application identities in your Azure tenant. You will create a **Native Client Application Identity** (no client secret required). 1. Open [Azure Portal](https://portal.azure.com) 2. Navigate to **Entra ID** 3. Go to **App registrations** → **New registration** 4. Fill out: - **Name**: Any name you like - **Supported account types**: `Accounts in this organization directory only` - **Redirect URI**: - Platform: `Public client/native (mobile & desktop)` - URI: `http://localhost` 5. Click **Register** 6. From the **Overview** page, note: - `Application (client) ID` - `Directory (tenant) ID` 7. Go to: `Manage` → `API permissions` - Click **Add permission** - Choose **APIs my organization uses** - Search for: **Power Platform API** If it's not listed, see **Tip** below. 8. Choose: - **Delegated Permissions** - Expand `CopilotStudio` - Select `CopilotStudio.Copilots.Invoke` 9. Click **Add permissions** 10. (Optional) Click **Grant admin consent** ### Tip If you **do not see Power Platform API**, follow [Step 2 in Power Platform API Authentication](https://learn.microsoft.com/en-us/power-platform/admin/programmability-authentication-v2) to add the API to your tenant. ================================================ FILE: dotnet/src/Agents/Core/AgentGroupChat.cs ================================================ // Copyright (c) Microsoft.

We suggest using .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets) to avoid the risk of leaking secrets into the repository, branches and pull requests. You can also use environment variables if you prefer. To set your secrets with Secret Manager: ``` cd dotnet/src/IntegrationTests dotnet user-secrets init dotnet user-secrets set "OpenAI:ServiceId" "gpt-3.5-turbo-instruct" dotnet user-secrets set "OpenAI:ModelId" "gpt-3.5-turbo-instruct" dotnet user-secrets set "OpenAI:ChatModelId" "gpt-4" dotnet user-secrets set "OpenAI:ApiKey" "..." dotnet user-secrets set "AzureOpenAI:ServiceId" "azure-gpt-35-turbo-instruct" dotnet user-secrets set "AzureOpenAI:DeploymentName" "gpt-35-turbo-instruct" dotnet user-secrets set "AzureOpenAI:ChatDeploymentName" "gpt-4" dotnet user-secrets set "AzureOpenAI:Endpoint" "https://contoso.openai.azure.com/" dotnet user-secrets set "AzureOpenAI:ApiKey" "..." dotnet user-secrets set "AzureOpenAIEmbeddings:ServiceId" "azure-text-embedding-ada-002" dotnet user-secrets set "AzureOpenAIEmbeddings:DeploymentName" "text-embedding-ada-002" dotnet user-secrets set "AzureOpenAIEmbeddings:Endpoint" "https://contoso.openai.azure.com/" dotnet user-secrets set "AzureOpenAIEmbeddings:ApiKey" "..." dotnet user-secrets set "Bing:ApiKey" "..." ``` ### Option 2: Use Configuration File 1. Create a `testsettings.development.json` file next to `testsettings.json`. This file will be ignored by git, the content will not end up in pull requests, so it's safe for personal settings. Keep the file safe. 2. Edit `testsettings.development.json` and 1. set you Azure OpenAI and OpenAI keys and settings found in Azure portal and OpenAI website. 2. set the `Bing:ApiKey` using the API key you can find in the Azure portal. For example: ```json { "OpenAI": { "ServiceId": "gpt-3.5-turbo-instruct", "ModelId": "gpt-3.5-turbo-instruct", "ChatModelId": "gpt-4", "ApiKey": "sk-...." }, "AzureOpenAI": { "ServiceId": "gpt-35-turbo-instruct", "DeploymentName": "gpt-35-turbo-instruct", "ChatDeploymentName": "gpt-4", "Endpoint": "https://contoso.openai.azure.com/", "ApiKey": "...." }, "OpenAIEmbeddings": { "ServiceId": "text-embedding-ada-002", "ModelId": "text-embedding-ada-002", "ApiKey": "sk-...." }, "AzureOpenAIEmbeddings": { "ServiceId": "azure-text-embedding-ada-002", "DeploymentName": "text-embedding-ada-002", "Endpoint": "https://contoso.openai.azure.com/", "ApiKey": "...." }, "Bing": { "ApiKey": "...." } } ``` ### Option 3: Use Environment Variables You may also set the test settings in your environment variables. The environment variables will override the settings in the `testsettings.development.json` file. When setting environment variables, use a double underscore (i.e. "\_\_") to delineate between parent and child properties. For example: - bash: ```bash export OpenAI__ApiKey="sk-...." export AzureOpenAI__ApiKey="...." export AzureOpenAI__DeploymentName="gpt-35-turbo-instruct" export AzureOpenAI__ChatDeploymentName="gpt-4" export AzureOpenAIEmbeddings__DeploymentName="azure-text-embedding-ada-002" export AzureOpenAI__Endpoint="https://contoso.openai.azure.com/" export Bing__ApiKey="...." ``` - PowerShell: ```ps $env:OpenAI__ApiKey = "sk-...." $env:AzureOpenAI__ApiKey = "...." $env:AzureOpenAI__DeploymentName = "gpt-35-turbo-instruct" $env:AzureOpenAI__ChatDeploymentName = "gpt-4" $env:AzureOpenAIEmbeddings__DeploymentName = "azure-text-embedding-ada-002" $env:AzureOpenAI__Endpoint = "https://contoso.openai.azure.com/" $env:Bing__ApiKey = "...." ``` ================================================ FILE: dotnet/src/Experimental/Orchestration.Flow.IntegrationTests/RedirectOutput.cs ================================================ // Copyright (c) Microsoft.

Deploy the following models: 1. `dall-e-3` DALL-E 3 generates images and is used in Text to Image tests. 1. `tts` TTS is a model that converts text to natural sounding speech and is used in Text to Audio tests. 1. `whisper` The Whisper models are trained for speech recognition and translation tasks and is used in Audio to Text tests. 1. `text-embedding-ada-002` Text Embedding Ada 002 is used in Text Embedding tests. 1. `gpt-35-turbo-instruct` GPT-3.5 Turbo Instruct is used in inference tests. 1. `gpt-4o` GPT-4o is used in chat completion tests. 1. Assign users who are running the integration tests the following roles: `Cognitive Services OpenAI Contributor` and `Cognitive Services OpenAI User` 1. Users must [Authenticate to Azure using Azure CLI](https://learn.microsoft.com/en-us/cli/azure/authenticate-azure-cli) 1. **OpenAI**: go to [OpenAI](https://platform.openai.com) to register and procure your API key. 1. **HuggingFace API key**: see https://huggingface.co/docs/huggingface_hub/guides/inference for details. 1. **Azure Bing Web Search API**: go to [Bing Web Search API](https://www.microsoft.com/en-us/bing/apis/bing-web-search-api) and select `Try Now` to get started. 1. **Postgres**: start a postgres with the [pgvector](https://github.com/pgvector/pgvector) extension installed. You can easily do it using the docker image [ankane/pgvector](https://hub.docker.com/r/ankane/pgvector). 1. **Weaviate**: go to `IntegrationTests/Connectors/Weaviate` where `docker-compose.yml` is located and run `docker-compose up --build`. ## Setup > [!IMPORTANT] > To run integration tests that depend on Azure OpenAI, you must have the Azure OpenAI models deployed and have the necessary permissions to access them. > These test authenticate using [AzureCliCredential](https://learn.microsoft.com/en-us/dotnet/api/azure.identity.azureclicredential?view=azure-dotnet). > Users must [Authenticate to Azure using Azure CLI](https://learn.microsoft.com/en-us/cli/azure/authenticate-azure-cli). ### Option 1: Use Secret Manager Integration tests will require secrets and credentials, to access OpenAI, Azure OpenAI, Bing and other resources. We suggest using .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets) to avoid the risk of leaking secrets into the repository, branches and pull requests. You can also use environment variables if you prefer. To set your secrets with Secret Manager: ``` cd dotnet/src/IntegrationTests dotnet user-secrets init dotnet user-secrets set "OpenAI:ServiceId" "gpt-3.5-turbo-instruct" dotnet user-secrets set "OpenAI:ModelId" "gpt-3.5-turbo-instruct" dotnet user-secrets set "OpenAI:ChatModelId" "gpt-4" dotnet user-secrets set "OpenAI:ApiKey" "..." dotnet user-secrets set "OpenAITextToImage:ServiceId" "dall-e-3" dotnet user-secrets set "OpenAITextToImage:ModelId" "dall-e-3" dotnet user-secrets set "OpenAITextToImage:ApiKey" "..." dotnet user-secrets set "OpenAIEmbeddings:ServiceId" "text-embedding-ada-002" dotnet user-secrets set "OpenAIEmbeddings:ModelId" "text-embedding-ada-002" dotnet user-secrets set "OpenAIEmbeddings:ApiKey" "..." dotnet user-secrets set "AzureAIInference:ServiceId" "azure-ai-inference" dotnet user-secrets set "AzureAIInference:ApiKey" "..." dotnet user-secrets set "AzureAIInference:Endpoint" "https://contoso.models.ai.azure.com/" dotnet user-secrets set "AzureOpenAI:ServiceId" "azure-gpt-35-turbo-instruct" dotnet user-secrets set "AzureOpenAI:DeploymentName" "gpt-35-turbo-instruct" dotnet user-secrets set "AzureOpenAI:ChatDeploymentName" "gpt-4" dotnet user-secrets set "AzureOpenAI:Endpoint" "https://contoso.openai.azure.com/" dotnet user-secrets set "AzureOpenAIEmbeddings:ServiceId" "azure-text-embedding-ada-002" dotnet user-secrets set "AzureOpenAIEmbeddings:DeploymentName" "text-embedding-ada-002" dotnet user-secrets set "AzureOpenAIEmbeddings:Endpoint" "https://contoso.openai.azure.com/" dotnet user-secrets set "AzureOpenAIAudioToText:ServiceId" "azure-audio-to-text" dotnet user-secrets set "AzureOpenAIAudioToText:DeploymentName" "whisper-1" dotnet user-secrets set "AzureOpenAIAudioToText:Endpoint" "https://contoso.openai.azure.com/" dotnet user-secrets set "AzureOpenAITextToAudio:ServiceId" "azure-text-to-audio" dotnet user-secrets set "AzureOpenAITextToAudio:DeploymentName" "tts-1" dotnet user-secrets set "AzureOpenAITextToAudio:Endpoint" "https://contoso.openai.azure.com/" dotnet user-secrets set "AzureOpenAITextToImage:ServiceId" "azure-text-to-image" dotnet user-secrets set "AzureOpenAITextToImage:DeploymentName" "dall-e-3" dotnet user-secrets set "AzureOpenAITextToImage:Endpoint" "https://contoso.openai.azure.com/" dotnet user-secrets set "MistralAI:ChatModel" "mistral-large-latest" dotnet user-secrets set "MistralAI:EmbeddingModel" "mistral-embed" dotnet user-secrets set "MistralAI:ApiKey" "..." dotnet user-secrets set "HuggingFace:ApiKey" "..." dotnet user-secrets set "Bing:ApiKey" "..." dotnet user-secrets set "Postgres:ConnectionString" "..." dotnet user-secrets set "Planners:AzureOpenAI:Endpoint" "https://contoso.openai.azure.com/" dotnet user-secrets set "Planners:AzureOpenAI:ChatDeploymentName" "gpt-4-1106-preview" dotnet user-secrets set "Planners:AzureOpenAI:ServiceId" "gpt-4-1106-preview" dotnet user-secrets set "Planners:AzureOpenAI:ApiKey" "..." dotnet user-secrets set "Planners:OpenAI:ModelId" "gpt-3.5-turbo-1106" dotnet user-secrets set "Planners:OpenAI:ApiKey" "..." dotnet user-secrets set "AzureAISearch:ServiceUrl" "..." dotnet user-secrets set "AzureAISearch:ApiKey" "..." ``` ### Option 2: Use Configuration File 1. Create a `testsettings.development.json` file next to `testsettings.json`. This file will be ignored by git, the content will not end up in pull requests, so it's safe for personal settings. Keep the file safe. 2. Edit `testsettings.development.json` and 1. set you Azure OpenAI and OpenAI keys and settings found in Azure portal and OpenAI website. 2. set the `Bing:ApiKey` using the API key you can find in the Azure portal. For example: ```json { "OpenAI": { "ServiceId": "gpt-3.5-turbo-instruct", "ModelId": "gpt-3.5-turbo-instruct", "ChatModelId": "gpt-4", "ApiKey": "sk-...." }, "AzureOpenAI": { "ServiceId": "azure-gpt-35-turbo-instruct", "DeploymentName": "gpt-35-turbo-instruct", "ChatDeploymentName": "gpt-4", "Endpoint": "https://contoso.openai.azure.com/", "ApiKey": "...." }, "OpenAIEmbeddings": { "ServiceId": "text-embedding-ada-002", "ModelId": "text-embedding-ada-002", "ApiKey": "sk-...." }, "AzureOpenAIEmbeddings": { "ServiceId": "azure-text-embedding-ada-002", "DeploymentName": "text-embedding-ada-002", "Endpoint": "https://contoso.openai.azure.com/", "ApiKey": "...." }, "HuggingFace": { "ApiKey": "" }, "Bing": { "ApiKey": "...." }, "Postgres": { "ConnectionString": "Host=localhost;Database=postgres;User Id=postgres;Password=mysecretpassword" } } ``` ### Option 3: Use Environment Variables You may also set the test settings in your environment variables. The environment variables will override the settings in the `testsettings.development.json` file. When setting environment variables, use a double underscore (i.e. "\_\_") to delineate between parent and child properties. For example: - bash: ```bash export OpenAI__ApiKey="sk-...." export AzureOpenAI__ApiKey="...." export AzureOpenAI__DeploymentName="gpt-35-turbo-instruct" export AzureOpenAI__ChatDeploymentName="gpt-4" export AzureOpenAIEmbeddings__DeploymentName="azure-text-embedding-ada-002" export AzureOpenAI__Endpoint="https://contoso.openai.azure.com/" export HuggingFace__ApiKey="...." export Bing__ApiKey="...." export Postgres__ConnectionString="...." ``` - PowerShell: ```ps $env:OpenAI__ApiKey = "sk-...." $env:AzureOpenAI__ApiKey = "...." $env:AzureOpenAI__DeploymentName = "gpt-35-turbo-instruct" $env:AzureOpenAI__ChatDeploymentName = "gpt-4" $env:AzureOpenAIEmbeddings__DeploymentName = "azure-text-embedding-ada-002" $env:AzureOpenAI__Endpoint = "https://contoso.openai.azure.com/" $env:HuggingFace__ApiKey = "...." $env:Bing__ApiKey = "...." $env:Postgres__ConnectionString = "...." ``` ================================================ FILE: dotnet/src/IntegrationTests/RedirectOutput.cs ================================================ // Copyright (c) Microsoft.

These integrations include AI services, memory connectors. Additionally, Semantic Kernel integrates with other Microsoft services to provide additional functionality via plugins. Filesystems in the Linux kernel ¶. Filesystems in the Linux kernel. ¶. This under-development manual will, some glorious day, provide comprehensive information on how the Linux virtual filesystem (VFS) layer works, along with the filesystems that sit below it. For now, what we have can be found below. Semantic Kernel allows prompts to be automatically converted to ChatHistory instances. Developers can create prompts which include tags and ... Anatomy of a plugin. At a high-level, a plugin is a group of functions that can be exposed to AI apps and services. The functions within plugins can then be orchestrated by an AI application to accomplish user requests. Within Semantic Kernel, you can invoke these functions automatically with function calling. Note. The biggest benefit of having a dedicated connector for Ollama is that it allows us to support Semantic Kernel features that targeted for Ollama deployed models. What is Ollama? Ollama is an open-source MIT license platform that facilitates the local operation of AI models directly on personal or corporate hardware. ================================================ FILE: dotnet/src/IntegrationTests/TestData/serializedChatHistoryV1_15_1.json ================================================ [ { "Role": { "Label": "user" }, "Items": [ { "$type": "TextContent", "Text": "Given the current time of day and weather, what is the likely color of the sky in Boston?" } ] }, { "Role": { "Label": "assistant" }, "Items": [ { "$type": "FunctionCallContent", "Id": "call_q5FoU2fpfEyZmvC6iqtIXPYQ", "PluginName": "HelperFunctions", "FunctionName": "Get_Weather_For_City", "Arguments": { "cityName": "Boston" } } ], "ModelId": "gpt-4", "Metadata": { "Id": "chatcmpl-9lf5Qgx7xquKec3tc6lTn27y8Lmkz", "Created": "2024-07-16T16:13:00+00:00", "PromptFilterResults": [], "SystemFingerprint": null, "Usage": { "CompletionTokens": 23, "PromptTokens": 196, "TotalTokens": 219 }, "ContentFilterResults": null, "FinishReason": "tool_calls", "FinishDetails": null, "LogProbabilityInfo": null, "Index": 0, "Enhancements": null, "ChatResponseMessage.FunctionToolCalls": [ { "Name": "HelperFunctions-Get_Weather_For_City", "Arguments": "{\n \u0022cityName\u0022: \u0022Boston\u0022\n}", "Id": "call_q5FoU2fpfEyZmvC6iqtIXPYQ" } ] } }, { "Role": { "Label": "tool" }, "Items": [ { "$type": "TextContent", "Text": "61 and rainy", "Metadata": { "ChatCompletionsToolCall.Id": "call_q5FoU2fpfEyZmvC6iqtIXPYQ" } }, { "$type": "FunctionResultContent", "CallId": "call_q5FoU2fpfEyZmvC6iqtIXPYQ", "PluginName": "HelperFunctions", "FunctionName": "Get_Weather_For_City", "Result": "61 and rainy" } ], "Metadata": { "ChatCompletionsToolCall.Id": "call_q5FoU2fpfEyZmvC6iqtIXPYQ" } }, { "Role": { "Label": "assistant" }, "Items": [ { "$type": "TextContent", "Text": "Given the current weather in Boston is 61\u00B0F and rainy, the likely color of the sky would be gray or overcast due to the presence of rain clouds.", "ModelId": "gpt-4", "Metadata": { "Id": "chatcmpl-9lf5RibNr9h4bzq7JJjUXj6ITz7wN", "Created": "2024-07-16T16:13:01+00:00", "PromptFilterResults": [], "SystemFingerprint": null, "Usage": { "CompletionTokens": 34, "PromptTokens": 237, "TotalTokens": 271 }, "ContentFilterResults": null, "FinishReason": "stop", "FinishDetails": null, "LogProbabilityInfo": null, "Index": 0, "Enhancements": null } } ], "ModelId": "gpt-4", "Metadata": { "Id": "chatcmpl-9lf5RibNr9h4bzq7JJjUXj6ITz7wN", "Created": "2024-07-16T16:13:01+00:00", "PromptFilterResults": [], "SystemFingerprint": null, "Usage": { "CompletionTokens": 34, "PromptTokens": 237, "TotalTokens": 271 }, "ContentFilterResults": null, "FinishReason": "stop", "FinishDetails": null, "LogProbabilityInfo": null, "Index": 0, "Enhancements": null } } ] ================================================ FILE: dotnet/src/IntegrationTests/TestData/test_content.txt ================================================ Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
