Security vulnerability, data loss/corruption, crash in\nproduction path, resource leak without cleanup, auth bypass.\n\n[Bug] — Must fix before merge. Logic error, behavioral regression, API contract\nviolation, race condition, missing await on coroutine, silent exception swallowing.\n\n[Perf] — Performance regression. O(n²)+ algorithmic complexity, unbounded collection\ngrowth, N+1 queries against VikingDB, redundant embedding/VLM API calls,\nunnecessary large object copies in hot paths.\n\n[Suggestion] — Recommended improvement. Missing tests, dead code, naming inconsistency,\npoor observability (missing telemetry/logging), unclear intent, unrelated changes in PR.\n\n## Rules (structured as: WHEN condition → THEN check → BECAUSE rationale)\n\n### PYTHON CORE (openviking/, openviking_cli/)\n\nR1. ASYNC DISCIPLINE\nWHEN code is inside an async function or coroutine\nTHEN verify all I/O calls use async variants (commit_async not commit,\n     httpx.AsyncClient not requests, async for on streams)\nBECAUSE blocking calls in async context starve the event loop.\n     Real bug: PR #728 replaced blocking commit() with commit_async().\n     Also check: missing `await` on coroutine calls (silent bug — returns\n     coroutine object instead of result).\n\nR2. MEMORY PIPELINE COMPLETENESS\nWHEN code touches MemoryCategory, MemoryExtractor, MemoryDeduplicator,\n     SessionCompressor, or MemoryArchiver\nTHEN verify all 6 categories are handled: PREFERENCES, ENTITIES, PATTERNS,\n     EVENTS, TOOLS, SKILLS. Check that match/if-elif chains on DedupDecision\n     (KEEP/MERGE/DELETE/SKIP) are exhaustive.\nBECAUSE partial handling silently drops memories. The 6-category model is\n     a core invariant of the extraction pipeline.\n\nR3. QUADRATIC REPROCESSING GUARD\nWHEN code enqueues items (SemanticMsg, embedding tasks) inside a loop that\n     also processes the queue, or when a callback re-enqueues work\nTHEN flag as [Perf] or [Bug] — this pattern causes O(n²) reprocessing.\nBECAUSE PR #505 fixed exactly this: misdirected SemanticMsg enqueue inside\n     a processing loop caused quadratic growth.\n\nR4. VLM/EMBEDDING API RESILIENCE\nWHEN code calls VLM providers (OpenAI, Doubao/Ark, Gemini) or embedding APIs\nTHEN verify: (a) timeout is set (ai_timeout or explicit), (b) retry/fallback\n     exists for transient failures, (c) streaming responses handle partial\n     failure gracefully, (d) JSON output uses json-repair not raw json.loads.\nBECAUSE PR #740 was reverted (#745) due to streaming response issues, then\n     re-landed in #756 with proper handling. This is a repeat-risk area.\n\nR5. TYPE SAFETY\nWHEN new Python code is added or modified\nTHEN check: no bare `type: ignore` (must have explanation comment), consistent\n     Optional[X] vs X|None style within each file, proper use of\n     TYPE_CHECKING imports for circular dependency avoidance.\nBECAUSE CI enforces ruff + mypy on changed files. Suppressions without\n     rationale hide real type errors.\n\nR6. LICENSE HEADERS\nWHEN a new .py file is created in openviking/ or openviking_cli/\nTHEN it MUST contain at the top:\n     # Copyright (c) 2026 Beijing Volcano Engine Technology Co., Ltd.\n     # SPDX-License-Identifier: Apache-2.0\nBECAUSE Apache-2.0 compliance requires headers on all source files.\n     Every existing file in these directories follows this convention.\n\nR7. ERROR HANDLING\nWHEN code uses try/except\nTHEN verify: no bare `except:` or `except Exception:` without logging (loguru)\n     or re-raising. Narrow exceptions to specific types where possible.\nBECAUSE PR #148f6e3 fixed overly broad `except Exception` to specific\n     (ImportError, ModuleNotFoundError, AttributeError). Broad catches hide\n     real bugs.\n\n### TYPESCRIPT / BOT (bot/, examples/openclaw-plugin/)\n\nR8. PLUGIN HOOK TIMEOUT\nWHEN code registers or modifies a hook handler (before_prompt_build,\n     after_prompt_build, etc.) or calls getClient()\nTHEN verify the call has timeout protection (Promise.race with timeout,\n     AbortController, or equivalent).\nBECAUSE PR #749 added timeout protection to getClient() after discovering\n     hooks could hang indefinitely, blocking the entire bot.\n\nR9. PROCESS LIFECYCLE\nWHEN code spawns child processes or manages bot lifecycle\nTHEN verify: SIGTERM/SIGINT handlers exist, stdio streams are properly\n     closed, and cleanup runs in all exit paths (including uncaught exceptions).\nBECAUSE the bot uses process-manager.ts for lifecycle; leaked processes or\n     file descriptors degrade the host system.\n\n### CROSS-CUTTING\n\nR10. API BACKWARD COMPATIBILITY\nWHEN a PR modifies public interfaces (FastAPI endpoints, SDK client params,\n     RequestContext fields, config keys in ov.conf)\nTHEN verify: existing params are not removed or renamed (only deprecated),\n     new params have defaults, multi-tenant changes preserve single-tenant\n     behavior as the default path.\nBECAUSE PR #767 added account/user params — these must be optional to avoid\n     breaking existing single-tenant deployments.\n\nR11. CONCURRENCY SAFETY\nWHEN code modifies shared mutable state (dicts, lists, sets) in async\n     functions, or uses _pending_semantic_changes or similar shared structures\nTHEN verify proper synchronization (asyncio.Lock, thread-safe collections)\n     and that no produce-and-consume-in-same-loop pattern exists.\nBECAUSE the SessionCompressor._pending_semantic_changes dict is accessed\n     from multiple async paths; unsynchronized access causes data races.\n\nR12. RETRIEVAL PIPELINE INTEGRITY\nWHEN code modifies find/rerank/search logic or ContextLevel scoring (L0/L1/L2)\nTHEN verify: rerank is optional (PR #754 fixed find-without-rerank), level-2\n     scores are preserved through the pipeline, and search results maintain\n     their ranking order.\nBECAUSE PR #754 fixed a bug where find() required rerank and level-2 scores\n     were silently dropped.\n\nR13. TESTING REQUIREMENTS\nWHEN a PR fixes a bug → it MUST include a regression test or explicitly\n     explain in the PR description why one is impractical.\nWHEN a PR adds a feature → it SHOULD include unit tests for the happy path\n     and at least one error/edge case.\nWHEN a PR modifies embedding/VLM integration → verify test isolation (no\n     hardcoded API keys — construct test keys dynamically as in PR #148f6e3).\nBECAUSE the repo uses pytest; test patterns should use fixtures, not globals.\n\nR14. DOCUMENTATION CONSISTENCY\nWHEN a PR modifies docs/ (en/ and zh/cn/ and ja/) or README files\nTHEN verify all language versions are updated consistently. Flag if only\n     one language is updated when the content change is substantive.\nBECAUSE the repo maintains en/zh/ja translations (PR #755 added Japanese docs).\n\nR15. TELEMETRY & OBSERVABILITY\nWHEN code adds or modifies operations that call external services (VLM, embedding,\n     VikingDB) or processes memories\nTHEN verify telemetry integration exists (get_current_telemetry pattern) and that\n     timing/count metrics are recorded for the operation.\nBECAUSE PR #735 added memory extract telemetry breakdown — new operations\n     should follow this pattern for production observability.\n\n## Output Format\nBe specific: reference exact variable names, function calls, line numbers.\nWhen suggesting a fix, include a minimal code block.\nMatch PR language (Chinese PR → Chinese review, English PR → English review).\n\"\"\"\n\n# ---------------------------------------------------------------------------\n# Improve Tool (code suggestions)\n# ---------------------------------------------------------------------------\n[pr_code_suggestions]\ncommitable_code_suggestions = false\npersistent_comment = true\nfocus_only_on_problems = true\n# Filter low-confidence suggestions. 0 = show all, 7+ = high quality only.\n# Set to 5 to balance signal-to-noise for this codebase.\nsuggestions_score_threshold = 5\n# Extended mode for thorough analysis of large PRs\nauto_extended_mode = true\nnum_code_suggestions_per_chunk = 4\nmax_number_of_calls = 3\nparallel_calls = true\n\nextra_instructions = \"\"\"\\\nFocus suggestions on these OpenViking-specific anti-patterns:\n\n1. BLOCKING IN ASYNC: Replace `commit()`, `requests.get()`, `time.sleep()` with\n   `commit_async()`, `httpx.AsyncClient`, `asyncio.sleep()` inside async functions.\n\n2. QUADRATIC LOOPS: Simplify nested loops over memory categories or semantic queues.\n   If an inner loop re-processes items already in the outer loop, suggest flattening\n   or using a set-based approach.\n\n3. PROMPT CONSTRUCTION: Extract repeated LLM prompt strings into Jinja2 templates\n   (the dependency exists in pyproject.toml). Inline f-string prompts over 5 lines\n   should be templated.\n\n4. LOGGING: Replace `print()` with `logger = get_logger(__name__)` (loguru pattern\n   used throughout the codebase). Include structured context in log messages.\n\n5. VALIDATION: Prefer pydantic models for API request/response validation over raw\n   dicts. The codebase already depends on pydantic>=2.0.0.\n\n6. API RESILIENCE: Flag any VLM/embedding API call missing timeout or retry logic.\n   Suggest wrapping with httpx timeout config or litellm retry patterns.\n\n7. RESOURCE CLEANUP: Ensure context managers (async with) are used for DB connections,\n   HTTP clients, and file handles.

    "content": "# Contributing Guide\n\nThank you for your interest in OpenViking! We welcome contributions of all kinds:\n\n- Bug reports\n- Feature requests\n- Documentation improvements\n- Code contributions\n\n---\n\n## Development Setup\n\n### Prerequisites\n\n- **Python**: 3.10+\n- **Go**: 1.22+ (Required for building AGFS components from source)\n- **Rust**: 1.88+ (Required for source builds because the bundled `ov` CLI is built during packaging)\n- **C++ Compiler**: GCC 9+ or Clang 11+ (Required for building core extensions, must support C++17)\n- **CMake**: 3.12+\n\n#### Platform-Specific Native Build Tools\n\n- **Linux**: Install `build-essential`; some environments may also require `pkg-config`\n- **macOS**: Install Xcode Command Line Tools (`xcode-select --install`)\n- **Windows**: Install CMake and MinGW for local native builds\n\n#### Supported Platforms (Pre-compiled Wheels)\n\nOpenViking provides pre-compiled **Wheel** packages for the following environments:\n\n- **Windows**: x86_64\n- **macOS**: x86_64, arm64 (Apple Silicon)\n- **Linux**: x86_64, arm64 (manylinux)\n\nFor other platforms (e.g., FreeBSD), the package will be automatically compiled from source during installation via `pip`. Ensure you have the [Prerequisites](#prerequisites) installed.\n\n### 1. Fork and Clone\n\n```bash\ngit clone https://github.com/YOUR_USERNAME/openviking.git\ncd openviking\n```\n\n### 2. Install Dependencies\n\nWe recommend using `uv` for Python environment management:\n\n```bash\n# Install uv (if not installed)\ncurl -LsSf https://astral.sh/uv/install.sh | sh\n\n# Sync dependencies and create virtual environment\nuv sync --all-extras\nsource .venv/bin/activate  # Linux/macOS\n# or .venv\\Scripts\\activate  # Windows\n```\n\n#### Local Development & Native Rebuilds\n\nOpenViking defaults to `binding-client` mode for AGFS, which requires pre-built native artifacts. If you modify the **AGFS (Go)** code, the bundled **Rust CLI**, or the **C++ extensions**, or if the pre-built artifacts are not found, you need to re-compile and re-install them. Run the following command in the project root:\n\n```bash\nuv pip install -e . --force-reinstall\n```\n\nThis command ensures that `setup.py` is re-executed, triggering rebuilds for AGFS, the bundled `ov` CLI, and the C++ components.\n\n### 3. Configure Environment\n\nCreate a configuration file `~/.openviking/ov.conf`:\n\n```json\n{\n  \"embedding\": {\n    \"dense\": {\n      \"provider\": \"volcengine\",\n      \"api_key\": \"your-api-key\",\n      \"model\": \"doubao-embedding-vision-250615\",\n      \"api_base\": \"https://ark.cn-beijing.volces.com/api/v3\",\n      \"dimension\": 1024,\n      \"input\": \"multimodal\"\n    }\n  },\n  \"vlm\": {\n    \"api_key\": \"your-api-key\",\n    \"model\": \"doubao-seed-2-0-pro-260215\",\n    \"api_base\": \"https://ark.cn-beijing.volces.com/api/v3\"\n  }\n}\n```\n\nSet the environment variable:\n\n```bash\nexport OPENVIKING_CONFIG_FILE=~/.openviking/ov.conf\n```\n\n### 4. Verify Installation\n\n```python\nimport asyncio\nimport openviking as ov\n\nasync def main():\n    client = ov.AsyncOpenViking(path=\"./test_data\")\n    await client.initialize()\n    print(\"OpenViking initialized successfully!\")\n    await client.close()\n\nasyncio.run(main())\n```\n\n### 5. Build Rust CLI (Optional)\n\nThe Rust CLI (`ov`) provides a high-performance command-line client for interacting with OpenViking Server.\n\nEven if you do not plan to use `ov` directly, the Rust toolchain is still required when building OpenViking from source because packaging also builds the bundled CLI binary.\n\n```bash\n# Build and install from source\ncargo install --path crates/ov_cli\n\n# Or use the quick install script (downloads pre-built binary)\ncurl -fsSL https://raw.githubusercontent.com/volcengine/OpenViking/main/crates/ov_cli/install.sh | bash\n```\n\nAfter installation, run `ov --help` to see all available commands. CLI connection config goes in `~/.openviking/ovcli.conf`.\n\n---\n\n## Project Structure\n\n```\nopenviking/\n├── pyproject.toml        # Project configuration\n├── Cargo.toml            # Rust workspace configuration\n├── third_party/          # Third-party dependencies\n│   └── agfs/             # AGFS filesystem\n│\n├── openviking/           # Python SDK\n│   ├── async_client.py   # AsyncOpenViking client\n│   ├── sync_client.py    # SyncOpenViking client\n│   ├── client/           # Local and HTTP client implementations\n│   ├── console/          # Standalone console UI and proxy service\n│   ├── core/             # Core data models and directory abstractions\n│   ├── message/          # Session message and part models\n│   ├── models/           # Embedding and VLM backends\n│   ├── parse/            # Resource parsers and detectors\n│   ├── resource/         # Resource processing and watch management\n│   ├── retrieve/         # Retrieval system\n│   ├── server/           # HTTP server\n│   ├── service/          # Shared service layer\n│   ├── session/          # Session management and compression\n│   ├── storage/          # Storage layer\n│   ├── telemetry/        # Operation telemetry\n│   ├── trace/            # Trace and runtime tracing helpers\n│   ├── utils/            # Utilities and configuration helpers\n│   └── prompts/          # Prompt templates\n│\n├── crates/               # Rust components\n│   └── ov_cli/           # Rust CLI client\n│       ├── src/          # CLI source code\n│       └── install.sh    # Quick install script\n│\n├── src/                  # C++ extensions (pybind11)\n│\n├── tests/                # Test suite\n│   ├── client/           # Client tests\n│   ├── console/          # Console tests\n│   ├── core/             # Core logic tests\n│   ├── parse/            # Parser tests\n│   ├── resource/         # Resource processing tests\n│   ├── retrieve/         # Retrieval tests\n│   ├── server/           # Server tests\n│   ├── service/          # Service layer tests\n│   ├── session/          # Session tests\n│   ├── storage/          # Storage tests\n│   ├── telemetry/        # Telemetry tests\n│   ├── vectordb/         # Vector database tests\n│   └── integration/      # End-to-end tests\n│\n└── docs/                 # Documentation\n    ├── en/               # English docs\n    └── zh/               # Chinese docs\n```\n\n---\n\n## Code Style\n\nWe use the following tools to maintain code consistency:\n\n| Tool | Purpose | Config |\n|------|---------|--------|\n| **Ruff** | Linting, Formatting, Import sorting | `pyproject.toml` |\n| **mypy** | Type checking | `pyproject.toml` |\n\n### Automated Checks (Recommended)\n\nWe use [pre-commit](https://pre-commit.com/) to automatically run these checks before every commit. This ensures your code always meets the standards without manual effort.\n\n1. **Install pre-commit**:\n   ```bash\n   pip install pre-commit\n   ```\n\n2. **Install the git hooks**:\n   ```bash\n   pre-commit install\n   ```\n\nNow, `ruff` (check & format) will run automatically when you run `git commit`. If any check fails, it may automatically fix the file. You just need to add the changes and commit again.\n\n### Running Checks\n\n```bash\n# Format code\nruff format openviking/\n\n# Lint\nruff check openviking/\n\n# Type check\nmypy openviking/\n```\n\n### Style Guidelines\n\n1. **Line width**: 100 characters\n2. **Indentation**: 4 spaces\n3. **Strings**: Prefer double quotes\n4. **Type hints**: Encouraged but not required\n5. **Docstrings**: Required for public APIs (1-2 lines max)\n\n---\n\n## Testing\n\n### Running Tests\n\n```bash\n# Run all tests\npytest\n\n# Run specific test module\npytest tests/client/ -v\npytest tests/server/ -v\npytest tests/parse/ -v\n\n# Run specific test file\npytest tests/client/test_lifecycle.py\n\n# Run specific test\npytest tests/client/test_lifecycle.py::TestClientInitialization::test_initialize_success\n\n# Run by keyword\npytest -k \"search\" -v\n\n# Run with coverage\npytest --cov=openviking --cov-report=term-missing\n```\n\n### Writing Tests\n\nTests are organized in subdirectories under `tests/`. The project uses `asyncio_mode = \"auto\"`, so async tests do **not** need the `@pytest.mark.asyncio` decorator:\n\n```python\n# tests/client/test_example.py\nfrom openviking import AsyncOpenViking\n\n\nclass TestAsyncOpenViking:\n    async def test_initialize(self, uninitialized_client: AsyncOpenViking):\n        await uninitialized_client.initialize()\n        assert uninitialized_client._service is not None\n        await uninitialized_client.close()\n\n    async def test_add_resource(self, client: AsyncOpenViking, sample_markdown_file):\n        result = await client.add_resource(\n            path=str(sample_markdown_file),\n            reason=\"test document\"\n        )\n        assert \"root_uri\" in result\n        assert result[\"root_uri\"].startswith(\"viking://\")\n```\n\nCommon fixtures are defined in `tests/conftest.py`, including `client` (initialized `AsyncOpenViking`), `uninitialized_client`, `temp_dir`, `sample_markdown_file`, and more.\n\n---\n\n## Contribution Workflow\n\n### 1. Create a Branch\n\n```bash\ngit checkout main\ngit pull origin main\ngit checkout -b feature/your-feature-name\n```\n\nBranch naming conventions:\n- `feature/xxx` - New features\n- `fix/xxx` - Bug fixes\n- `docs/xxx` - Documentation updates\n- `refactor/xxx` - Code refactoring\n\n### 2.

Our workflows are designed to be modular and tiered.\n\n### 1. Automatic Workflows\n\n| Event | Workflow | Description |\n|-------|----------|-------------|\n| **Pull Request** | `pr.yml` | Runs **Lint** (Ruff, Mypy) and **Test Lite** (Integration tests on Linux + Python 3.10). Provides fast feedback for contributors. (Displayed as **01. Pull Request Checks**) |\n| **Push to Main** | `ci.yml` | Runs **Test Full** (All OS: Linux/Win/Mac, All Py versions: 3.10-3.14) and **CodeQL** (Security scan). Ensures main branch stability. (Displayed as **02. Main Branch Checks**) |\n| **Release Published** | `release.yml` | Triggered when you create a Release on GitHub. Automatically builds source distribution and wheels, determines version from Git Tag, and publishes to **PyPI**. (Displayed as **03. Release**) |\n| **Weekly Cron** | `schedule.yml` | Runs **CodeQL** security scan every Sunday. (Displayed as **04. Weekly Security Scan**) |\n\nOther repository workflows also exist for PR review automation, Docker image builds, and Rust CLI packaging.\n\n### 2. Manual Trigger Workflows\n\nMaintainers can manually trigger the following workflows from the \"Actions\" tab to perform specific tasks or debug issues.\n\n#### A. Lint Checks (`11. _Lint Checks`)\nRuns code style checks (Ruff) and type checks (Mypy). No arguments required.\n\n> **Tip**: It is recommended to install [pre-commit](https://pre-commit.com/) locally to run these checks automatically before committing (see [Automated Checks](#automated-checks-recommended) section above).\n\n#### B. Test Suite (Lite) (`12. _Test Suite (Lite)`)\nRuns fast integration tests, supports custom matrix configuration.\n\n*   **Inputs**:\n    *   `os_json`: JSON string array of OS to run on (e.g., `[\"ubuntu-24.04\"]`).\n    *   `python_json`: JSON string array of Python versions (e.g., `[\"3.10\"]`).\n\n#### C. Test Suite (Full) (`13. _Test Suite (Full)`)\nRuns the full test suite on all supported platforms (Linux/Mac/Win) and Python versions (3.10-3.14). Supports custom matrix configuration when triggered manually.\n\n*   **Inputs**:\n    *   `os_json`: List of OS to run on (Default: `[\"ubuntu-24.04\", \"macos-14\", \"windows-latest\"]`).\n    *   `python_json`: List of Python versions (Default: `[\"3.10\", \"3.11\", \"3.12\", \"3.13\", \"3.14\"]`).\n\n#### D. Security Scan (`14. _CodeQL Scan`)\nRuns CodeQL security analysis. No arguments required.\n\n#### E. Build Distribution (`15. _Build Distribution`)\nBuilds Python wheel packages only, does not publish.\n\n*   **Inputs**:\n    *   `os_json`: List of OS to build on (Default: `[\"ubuntu-24.04\", \"ubuntu-24.04-arm\", \"macos-14\", \"macos-15-intel\", \"windows-latest\"]`).\n    *   `python_json`: List of Python versions (Default: `[\"3.10\", \"3.11\", \"3.12\", \"3.13\", \"3.14\"]`).\n    *   `build_sdist`: Whether to build source distribution (Default: `true`).\n    *   `build_wheels`: Whether to build wheel distribution (Default: `true`).\n\n#### F. Publish Distribution (`16. _Publish Distribution`)\nPublishes built packages (requires build Run ID) to PyPI.\n\n*   **Inputs**:\n    *   `target`: Select publish target (`testpypi`, `pypi`, `both`).\n    *   `build_run_id`: Build Workflow Run ID (Required, get it from the Build run URL).\n\n#### G. Manual Release (`03. Release`)\nOne-stop build and publish (includes build and publish steps).\n\n> **Version Numbering & Tag Convention**:\n> This project uses `setuptools_scm` to automatically extract version numbers from Git Tags.\n> *   **Tag Naming Convention**: Must follow the `vX.Y.Z` format (e.g., `v0.1.0`, `v1.2.3`). Tags must be compliant with Semantic Versioning.\n> *   **Release Build**: When a Release event is triggered, the version number directly corresponds to the Git Tag (e.g., `v0.1.0` -> `0.1.0`).\n> *   **Manual/Non-Tag Build**: The version number will include the commit count since the last Tag (e.g., `0.1.1.dev3`).\n> *   **Confirm Version**: After the publish job completes, you can see the published version directly in the **Notifications** area at the top of the Workflow **Summary** page (e.g., `Successfully published to PyPI with version: 0.1.8`). You can also verify it in the logs or the **Artifacts** filenames.\n\n*   **Inputs**:\n    *   `target`: Select publish target.\n        *   `none`: Build artifacts only (no publish). Used for verifying build capability.\n        *   `testpypi`: Publish to TestPyPI. Used for Beta testing.\n        *   `pypi`: Publish to official PyPI.\n        *   `both`: Publish to both.\n    *   `os_json`: Build platforms (Default includes all).\n    *   `python_json`: Python versions (Default includes all).\n    *   `build_sdist`: Whether to build source distribution (Default: `true`).\n    *   `build_wheels`: Whether to build wheel distribution (Default: `true`).\n\n> **Publishing Notes**:\n> *   **Test First**: It is strongly recommended to publish to **TestPyPI** for verification before publishing to official PyPI. Note that PyPI and TestPyPI are completely independent environments, and accounts and package data are not shared.\n> *   **No Overwrites**: Neither PyPI nor TestPyPI allow overwriting existing packages with the same name and version. If you need to republish, you must upgrade the version number (e.g., tag a new version or generate a new dev version). If you try to publish an existing version, the workflow will fail.\n\n---\n\n## Issue Guidelines\n\n### Bug Reports\n\nPlease provide:\n\n1. **Environment**\n   - Python version\n   - OpenViking version\n   - Operating system\n\n2. **Steps to Reproduce**\n   - Detailed steps\n   - Code snippets\n\n3. **Expected vs Actual Behavior**\n\n4. **Error Logs** (if any)\n\n### Feature Requests\n\nPlease describe:\n\n1. **Problem**: What problem are you trying to solve?\n2. **Solution**: What solution do you propose?\n3. **Alternatives**: Have you considered other approaches?\n\n---\n\n## Documentation\n\nDocumentation is in Markdown format under `docs/`:\n\n- `docs/en/` - English documentation\n- `docs/zh/` - Chinese documentation\n\n### Documentation Guidelines\n\n1.

    "content": "# 贡献指南\n\n感谢你对 OpenViking 感兴趣！我们欢迎各种形式的贡献：\n\n- 报告 Bug\n- 提交功能请求\n- 改进文档\n- 贡献代码\n\n---\n\n## 开发环境设置\n\n### 前置要求\n\n- **Python**: 3.10+\n- **Go**: 1.22+ (从源码构建 AGFS 组件需要)\n- **Rust**: 1.88+（从源码构建需要；打包流程会同时构建内置 `ov` CLI）\n- **C++ 编译器**: GCC 9+ 或 Clang 11+ (构建核心扩展需要，必须支持 C++17)\n- **CMake**: 3.12+\n\n#### 平台相关的本地构建工具\n\n- **Linux**: 建议安装 `build-essential`；某些环境下还可能需要 `pkg-config`\n- **macOS**: 安装 Xcode Command Line Tools（`xcode-select --install`）\n- **Windows**: 本地原生构建建议安装 CMake 和 MinGW\n\n#### 支持的平台 (预编译 Wheel 包)\n\nOpenViking 为以下环境提供预编译的 **Wheel** 包，安装时无需本地编译：\n\n- **Windows**: x86_64\n- **macOS**: x86_64, arm64 (Apple Silicon)\n- **Linux**: x86_64, arm64 (manylinux)\n\n对于其他平台（如 FreeBSD 等），安装时 `pip` 将会自动从源码进行编译。请确保已安装上述[前置要求](#前置要求)中的工具。\n\n### 1. Fork 并克隆\n\n```bash\ngit clone https://github.com/YOUR_USERNAME/openviking.git\ncd openviking\n```\n\n### 2. 安装依赖\n\n我们推荐使用 `uv` 进行 Python 环境管理：\n\n```bash\n# 安装 uv (如果尚未安装)\ncurl -LsSf https://astral.sh/uv/install.sh | sh\n\n# 同步依赖并创建虚拟环境\nuv sync --all-extras\nsource .venv/bin/activate  # Linux/macOS\n# 或者 .venv\\Scripts\\activate  # Windows\n```\n\n#### 本地开发与原生组件重建\n\nOpenViking 默认使用 `binding-client` 模式，这依赖预先构建的原生产物。如果你修改了 **AGFS (Go)** 代码、内置的 **Rust CLI**，或 **C++ 扩展**，或者这些预编译产物未找到，你需要重新编译并安装它们，以使更改在本地环境中生效。在项目根目录下运行以下命令：\n\n```bash\nuv pip install -e . --force-reinstall\n```\n\n该命令会强制重新执行 `setup.py`，触发 AGFS、内置 `ov` CLI 和 C++ 组件的重新编译与安装。\n\n### 3. 配置环境\n\n创建配置文件 `~/.openviking/ov.conf`：\n\n```json\n{\n  \"embedding\": {\n    \"dense\": {\n      \"provider\": \"volcengine\",\n      \"api_key\": \"your-api-key\",\n      \"model\": \"doubao-embedding-vision-250615\",\n      \"api_base\": \"https://ark.cn-beijing.volces.com/api/v3\",\n      \"dimension\": 1024,\n      \"input\": \"multimodal\"\n    }\n  },\n  \"vlm\": {\n    \"api_key\": \"your-api-key\",\n    \"model\": \"doubao-seed-2-0-pro-260215\",\n    \"api_base\": \"https://ark.cn-beijing.volces.com/api/v3\"\n  }\n}\n```\n\n设置环境变量：\n\n```bash\nexport OPENVIKING_CONFIG_FILE=~/.openviking/ov.conf\n```\n\n### 4. 验证安装\n\n```python\nimport asyncio\nimport openviking as ov\n\nasync def main():\n    client = ov.AsyncOpenViking(path=\"./test_data\")\n    await client.initialize()\n    print(\"OpenViking initialized successfully!\")\n    await client.close()\n\nasyncio.run(main())\n```\n\n### 5. 构建 Rust CLI（可选）\n\nRust CLI (`ov`) 提供高性能的命令行客户端，用于连接 OpenViking Server 进行操作。\n\n即使你不打算直接使用 `ov`，只要走 OpenViking 的源码构建流程，Rust 工具链仍然是必需的，因为打包过程也会构建内置 CLI 二进制。\n\n```bash\n# 从源码编译安装\ncargo install --path crates/ov_cli\n\n# 或者使用一键安装脚本（下载预编译二进制）\ncurl -fsSL https://raw.githubusercontent.com/volcengine/OpenViking/main/crates/ov_cli/install.sh | bash\n```\n\n安装后通过 `ov --help` 查看所有可用命令。CLI 连接配置见 `~/.openviking/ovcli.conf`。\n\n---\n\n## 项目结构\n\n```\nopenviking/\n├── pyproject.toml        #

    "content": "# コントリビューションガイド\n\nOpenVikingに興味をお持ちいただきありがとうございます！あらゆる種類のコントリビューションを歓迎します：\n\n- バグレポート\n- 機能リクエスト\n- ドキュメントの改善\n- コードのコントリビューション\n\n---\n\n## 開発環境のセットアップ\n\n### 前提条件\n\n- **Python**: 3.10以上\n- **Go**: 1.22以上（AGFSコンポーネントのソースビルドに必要）\n- **Rust**: 1.88以上（ソースビルド時に同梱の `ov` CLI もビルドされるため必須）\n- **C++コンパイラ**: GCC 9以上 または Clang 11以上（コア拡張のビルドに必要、C++17サポートが必須）\n- **CMake**: 3.12以上\n\n#### プラットフォーム別のネイティブビルドツール\n\n- **Linux**: `build-essential` の導入を推奨。環境によっては `pkg-config` も必要です\n- **macOS**: Xcode Command Line Tools をインストール（`xcode-select --install`）\n- **Windows**: ローカルのネイティブビルドには CMake と MinGW を推奨\n\n#### サポートされているプラットフォーム（プリコンパイル済みWheel）\n\nOpenVikingは以下の環境向けにプリコンパイル済み**Wheel**パッケージを提供しています：\n\n- **Windows**: x86_64\n- **macOS**: x86_64、arm64（Apple Silicon）\n- **Linux**: x86_64、arm64（manylinux）\n\nその他のプラットフォーム（例：FreeBSD）では、`pip`によるインストール時にソースから自動コンパイルされます。[前提条件](#前提条件)がインストールされていることを確認してください。\n\n### 1. フォークとクローン\n\n```bash\ngit clone https://github.com/YOUR_USERNAME/openviking.git\ncd openviking\n```\n\n### 2. 依存関係のインストール\n\nPython環境管理には`uv`の使用を推奨します：\n\n```bash\n# uvのインストール（未インストールの場合）\ncurl -LsSf https://astral.sh/uv/install.sh | sh\n\n# 依存関係の同期と仮想環境の作成\nuv sync --all-extras\nsource .venv/bin/activate  # Linux/macOS\n# または .venv\\Scripts\\activate  # Windows\n```\n\n#### ローカル開発とネイティブコンポーネントの再ビルド\n\nOpenVikingはAGFSに対してデフォルトで`binding-client`モードを使用し、事前にビルドされたネイティブ成果物を利用します。**AGFS（Go）**コード、同梱の**Rust CLI**、または**C++拡張**を変更した場合や、プリビルド成果物が見つからない場合は、再コンパイルと再インストールが必要です。プロジェクトルートで以下のコマンドを実行してください：\n\n```bash\nuv pip install -e . --force-reinstall\n```\n\nこのコマンドにより`setup.py`が再実行され、AGFS、同梱 `ov` CLI、C++コンポーネントの再ビルドがトリガーされます。\n\n### 3. 環境設定\n\n設定ファイル `~/.openviking/ov.conf` を作成します：\n\n```json\n{\n  \"embedding\": {\n    \"dense\": {\n      \"provider\": \"volcengine\",\n      \"api_key\": \"your-api-key\",\n      \"model\": \"doubao-embedding-vision-250615\",\n      \"api_base\": \"https://ark.cn-beijing.volces.com/api/v3\",\n      \"dimension\": 1024,\n      \"input\": \"multimodal\"\n    }\n  },\n  \"vlm\": {\n    \"api_key\": \"your-api-key\",\n    \"model\": \"doubao-seed-2-0-pro-260215\",\n    \"api_base\": \"https://ark.cn-beijing.volces.com/api/v3\"\n  }\n}\n```\n\n環境変数を設定します：\n\n```bash\nexport OPENVIKING_CONFIG_FILE=~/.openviking/ov.conf\n```\n\n### 4. インストールの確認\n\n```python\nimport asyncio\nimport openviking as ov\n\nasync def main():\n    client = ov.AsyncOpenViking(path=\"./test_data\")\n    await client.initialize()\n    print(\"OpenViking initialized successfully!\")\n    await client.close()\n\nasyncio.run(main())\n```\n\n### 5. Rust CLIのビルド（オプション）\n\nRust CLI（`ov`）は、OpenViking Serverとやり取りするための高性能コマンドラインクライアントを提供します。\n\n`ov` を直接使わない場合でも、OpenViking をソースからビルドするなら Rust ツールチェーンは必要です。パッケージング時に同梱 CLI バイナリも一緒にビルドされるためです。\n\n**前提条件**: Rust >= 1.88\n\n```bash\n# ソースからビルドしてインストール\ncargo install --path crates/ov_cli\n\n# またはクイックインストールスクリプトを使用（プリビルドバイナリをダウンロード）\ncurl -fsSL https://raw.githubusercontent.com/volcengine/OpenViking/main/crates/ov_cli/install.sh | bash\n```\n\nインストール後、`ov --help`を実行して利用可能なすべてのコマンドを確認できます。CLI接続設定は`~/.openviking/ovcli.conf`に記述します。\n\n---\n\n## プロジェクト構成\n\n```\nopenviking/\n├── pyproject.toml        # プロジェクト設定\n├── Cargo.toml            # Rustワークスペース設定\n├── third_party/          # サードパーティ依存関係\n│   └── agfs/             # AGFSファイルシステム\n│\n├── openviking/           # Python SDK\n│   ├── async_client.py   # AsyncOpenVikingクライアント\n│   ├── sync_client.py    # SyncOpenVikingクライアント\n│   ├── client/           # ローカル / HTTP クライアント実装\n│   ├── console/          # スタンドアロン console UI とプロキシサービス\n│   ├── core/             # コアデータモデルとディレクトリ抽象\n│   ├── message/          # セッションメッセージと part モデル\n│   ├── models/           # Embedding / VLM バックエンド\n│   ├── parse/            # リソースパーサーと検出器\n│   ├── resource/         # リソース処理と watch 管理\n│   ├── retrieve/         # 検索システム\n│   ├── server/           # HTTPサーバー\n│   ├── service/          # 共通 service レイヤー\n│   ├── session/          # セッション管理と圧縮\n│   ├── storage/          # ストレージレイヤー\n│   ├── telemetry/        # オペレーション telemetry\n│   ├── trace/            # trace とランタイム追跡補助\n│   ├── utils/            # ユーティリティと設定補助\n│   └── prompts/          # プロンプトテンプレート\n│\n├── crates/               # Rustコンポーネント\n│   └── ov_cli/           # Rust CLIクライアント\n│       ├── src/          # CLIソースコード\n│       └── install.sh    # クイックインストールスクリプト\n│\n├── src/                  # C++拡張（pybind11）\n│\n├── tests/                # テストスイート\n│   ├── client/           # クライアントテスト\n│   ├── console/          # Console テスト\n│   ├── core/             # コアロジックテスト\n│   ├── parse/            # パーサーテスト\n│   ├── resource/         # リソース処理テスト\n│   ├── retrieve/         # 検索テスト\n│   ├── server/           # サーバーテスト\n│   ├── service/          # Service レイヤーテスト\n│   ├── session/          # セッションテスト\n│   ├── storage/          # ストレージテスト\n│   ├── telemetry/        # Telemetry テスト\n│   ├── vectordb/         # ベクトルデータベーステスト\n│   └── integration/      # E2E テスト\n│\n└── docs/                 # ドキュメント\n    ├── en/               # 英語ドキュメント\n    └── zh/               # 中国語ドキュメント\n```\n\n---\n\n## コードスタイル\n\nコードの一貫性を維持するために以下のツールを使用しています：\n\n| ツール | 目的 | 設定 |\n|------|---------|--------|\n| **Ruff** | リンティング、フォーマット、インポートソート | `pyproject.toml` |\n| **mypy** | 型チェック | `pyproject.toml` |\n\n### 自動チェック（推奨）\n\n[pre-commit](https://pre-commit.com/)を使用して、コミット前にこれらのチェックを自動実行します。これにより、手動の作業なしでコードが常に基準を満たすことが保証されます。\n\n1. **pre-commitのインストール**:\n   ```bash\n   pip install pre-commit\n   ```\n\n2. **gitフックのインストール**:\n   ```bash\n   pre-commit install\n   ```\n\nこれで、`git commit`実行時に`ruff`（チェックとフォーマット）が自動的に実行されます。チェックが失敗した場合、ファイルが自動修正されることがあります。変更をaddして再度コミットするだけです。\n\n### チェックの実行\n\n```bash\n# コードのフォーマット\nruff format openviking/\n\n# リント\nruff check openviking/\n\n# 型チェック\nmypy openviking/\n```\n\n### スタイルガイドライン\n\n1. **行幅**: 100文字\n2. **インデント**: スペース4つ\n3. **文字列**: ダブルクォートを推奨\n4. **型ヒント**: 推奨（必須ではない）\n5. **Docstring**: パブリックAPIには必須（最大1〜2行）\n\n---\n\n## テスト\n\n### テストの実行\n\n```bash\n# 全テストの実行\npytest\n\n# 特定のテストモジュールの実行\npytest tests/client/ -v\npytest tests/server/ -v\npytest tests/parse/ -v\n\n# 特定のテストファイルの実行\npytest tests/client/test_lifecycle.py\n\n# 特定のテストの実行\npytest tests/client/test_lifecycle.py::TestClientInitialization::test_initialize_success\n\n# キーワードで実行\npytest -k \"search\" -v\n\n# カバレッジ付きで実行\npytest --cov=openviking --cov-report=term-missing\n```\n\n### テストの書き方\n\nテストは`tests/`配下のサブディレクトリに整理されています。プロジェクトは`asyncio_mode = \"auto\"`を使用しているため、非同期テストに`@pytest.mark.asyncio`デコレーターは**不要**です：\n\n```python\n# tests/client/test_example.py\nfrom openviking import AsyncOpenViking\n\n\nclass TestAsyncOpenViking:\n    async def test_initialize(self, uninitialized_client: AsyncOpenViking):\n        await uninitialized_client.initialize()\n        assert uninitialized_client._service is not None\n        await uninitialized_client.close()\n\n    async def test_add_resource(self, client: AsyncOpenViking, sample_markdown_file):\n        result = await client.add_resource(\n            path=str(sample_markdown_file),\n            reason=\"test document\"\n        )\n        assert \"root_uri\" in result\n        assert result[\"root_uri\"].startswith(\"viking://\")\n```\n\n共通フィクスチャは`tests/conftest.py`に定義されており、`client`（初期化済み`AsyncOpenViking`）、`uninitialized_client`、`temp_dir`、`sample_markdown_file` などが含まれます。\n\n---\n\n## コントリビューションワークフロー\n\n### 1. ブランチの作成\n\n```bash\ngit checkout main\ngit pull origin main\ngit checkout -b feature/your-feature-name\n```\n\nブランチ命名規則：\n- `feature/xxx` -

Release`)\nワンストップのビルドと公開（ビルドと公開ステップを含む）。\n\n> **バージョン番号とタグ規約**:\n> このプロジェクトは`setuptools_scm`を使用してGitタグからバージョン番号を自動抽出します。\n> *   **タグ命名規約**: `vX.Y.Z`形式に従う必要があります（例：`v0.1.0`、`v1.2.3`）。タグはセマンティックバージョニングに準拠する必要があります。\n> *   **リリースビルド**: リリースイベントがトリガーされると、バージョン番号はGitタグに直接対応します（例：`v0.1.0` -> `0.1.0`）。\n> *   **手動/非タグビルド**: バージョン番号には最後のタグからのコミット数が含まれます（例：`0.1.1.dev3`）。\n> *   **バージョン確認**: 公開ジョブ完了後、ワークフロー**Summary**ページ上部の**Notifications**エリアで公開バージョンを直接確認できます（例：`Successfully published to PyPI with version: 0.1.8`）。ログまたは**Artifacts**のファイル名でも確認できます。\n\n*   **入力**:\n    *   `target`: 公開先を選択。\n        *   `none`: アーティファクトのビルドのみ（公開なし）。ビルド機能の検証に使用。\n        *   `testpypi`: TestPyPIに公開。ベータテストに使用。\n        *   `pypi`: 公式PyPIに公開。\n        *   `both`: 両方に公開。\n    *   `os_json`: ビルドプラットフォーム（デフォルトはすべて含む）。\n    *   `python_json`: Pythonバージョン（デフォルトはすべて含む）。\n    *   `build_sdist`: ソースディストリビューションをビルドするか（デフォルト：`true`）。\n    *   `build_wheels`: wheelディストリビューションをビルドするか（デフォルト：`true`）。\n\n> **公開に関する注意事項**:\n> *   **先にテスト**: 公式PyPIに公開する前に、**TestPyPI**で検証することを強く推奨します。PyPIとTestPyPIは完全に独立した環境であり、アカウントやパッケージデータは共有されません。\n> *   **上書き不可**: PyPIもTestPyPIも、同じ名前とバージョンの既存パッケージの上書きを許可しません。再公開が必要な場合は、バージョン番号をアップグレードする必要があります（例：新しいバージョンをタグ付けするか、新しいdevバージョンを生成）。既存のバージョンを公開しようとすると、ワークフローが失敗します。\n\n---\n\n## Issueガイドライン\n\n### バグレポート\n\n以下を提供してください：\n\n1. **環境**\n   - Pythonバージョン\n   - OpenVikingバージョン\n   - オペレーティングシステム\n\n2. **再現手順**\n   - 詳細な手順\n   - コードスニペット\n\n3. **期待される動作と実際の動作**\n\n4. **エラーログ**（ある場合）\n\n### 機能リクエスト\n\n以下を記述してください：\n\n1. **問題**: どのような問題を解決しようとしていますか？\n2. **解決策**: どのような解決策を提案しますか？\n3. **代替案**: 他のアプローチを検討しましたか？\n\n---\n\n## ドキュメント\n\nドキュメントは`docs/`配下にMarkdown形式で管理されています：\n\n- `docs/en/` - 英語ドキュメント\n- `docs/zh/` - 中国語ドキュメント\n\n### ドキュメントガイドライン\n\n1. コード例は実行可能であること\n2. ドキュメントとコードの同期を維持すること\n3. 明確で簡潔な言葉を使用すること\n\n---\n\n## 行動規範\n\nこのプロジェクトに参加することで、以下に同意するものとします：\n\n1. **敬意を持つ**: 友好的でプロフェッショナルな態度を維持する\n2. **包括的である**: あらゆるバックグラウンドのコントリビューターを歓迎する\n3. **建設的である**: 有益なフィードバックを提供する\n4. **集中する**: 議論を技術的な内容に保つ\n\n---\n\n## ヘルプ\n\n質問がある場合：\n\n- [GitHub Issues](https://github.com/volcengine/openviking/issues)\n- [Discussions](https://github.com/volcengine/openviking/discussions)\n\n---\n\nコントリビューションありがとうございます！\n"

When building AI Agents, developers often face these challenges:\n\n- **Fragmented Context**: Memories are in code, resources are in vector databases, and skills are scattered, making them difficult to manage uniformly.\n- **Surging Context Demand**: An Agent's long-running tasks produce context at every execution. Simple truncation or compression leads to information loss.\n- **Poor Retrieval Effectiveness**: Traditional RAG uses flat storage, lacking a global view and making it difficult to understand the full context of information.\n- **Unobservable Context**: The implicit retrieval chain of traditional RAG is like a black box, making it hard to debug when errors occur.\n- **Limited Memory Iteration**: Current memory is just a record of user interactions, lacking Agent-related task memory.\n\n### The OpenViking Solution\n\n**OpenViking** is an open-source **Context Database** designed specifically for AI Agents.\n\nWe aim to define a minimalist context interaction paradigm for Agents, allowing developers to completely say goodbye to the hassle of context management. OpenViking abandons the fragmented vector storage model of traditional RAG and innovatively adopts a **\"file system paradigm\"** to unify the structured organization of memories, resources, and skills needed by Agents.\n\nWith OpenViking, developers can build an Agent's brain just like managing local files:\n\n- **Filesystem Management Paradigm** → **Solves Fragmentation**: Unified context management of memories, resources, and skills based on a filesystem paradigm.\n- **Tiered Context Loading** → **Reduces Token Consumption**: L0/L1/L2 three-tier structure, loaded on demand, significantly saving costs.\n- **Directory Recursive Retrieval** → **Improves Retrieval Effect**: Supports native filesystem retrieval methods, combining directory positioning with semantic search to achieve recursive and precise context acquisition.\n- **Visualized Retrieval Trajectory** → **Observable Context**: Supports visualization of directory retrieval trajectories, allowing users to clearly observe the root cause of issues and guide retrieval logic optimization.\n- **Automatic Session Management** → **Context Self-Iteration**: Automatically compresses content, resource references, tool calls, etc., in conversations, extracting long-term memory, making the Agent smarter with use.\n\n---\n\n## Quick Start\n\n### Prerequisites\n\nBefore starting with OpenViking, please ensure your environment meets the following requirements:\n\n- **Python Version**: 3.10 or higher\n- **Go Version**: 1.22 or higher (Required for building AGFS components)\n- **C++ Compiler**: GCC 9+ or Clang 11+ (Required for building core extensions)\n- **Operating System**: Linux, macOS, Windows\n- **Network Connection**: A stable network connection is required (for downloading dependencies and accessing model services)\n\n### 1. Installation\n\n#### Python Package\n\n```bash\npip install openviking --upgrade --force-reinstall\n```\n\n#### Rust CLI (Optional)\n\n```bash\ncurl -fsSL https://raw.githubusercontent.com/volcengine/OpenViking/main/crates/ov_cli/install.sh | bash\n```\n\nOr build from source:\n\n```bash\ncargo install --git https://github.com/volcengine/OpenViking ov_cli\n```\n\n### 2. Model Preparation\n\nOpenViking requires the following model capabilities:\n- **VLM Model**: For image and content understanding\n- **Embedding Model**: For vectorization and semantic retrieval\n\n#### Supported VLM Providers\n\nOpenViking supports three VLM providers:\n\n| Provider | Description | Get API Key |\n|----------|-------------|-------------|\n| `volcengine` | Volcengine Doubao Models | [Volcengine Console](https://console.volcengine.com/ark/region:ark+cn-beijing/overview?briefPage=0&briefType=introduce&type=new&utm_content=OpenViking&utm_medium=devrel&utm_source=OWO&utm_term=OpenViking) |\n| `openai` | OpenAI Official API | [OpenAI Platform](https://platform.openai.com) |\n| `litellm` | Unified access to various third-party models (Anthropic, DeepSeek, Gemini, vLLM, Ollama, etc.) | See [LiteLLM Providers](https://docs.litellm.ai/docs/providers) |\n\n> 💡 **Tip**:\n> - `litellm` supports unified access to various models. The `model` field must follow the [LiteLLM format specification](https://docs.litellm.ai/docs/providers)\n> - The system auto-detects common models (e.g., `claude-*`, `deepseek-*`, `gemini-*`, `hosted_vllm/*`, `ollama/*`, etc.). For other models, use the full prefix according to LiteLLM format\n\n#### Provider-Specific Notes\n\n<details>\n<summary><b>Volcengine (Doubao)</b></summary>\n\nVolcengine supports both model names and endpoint IDs. Using model names is recommended for simplicity:\n\n```json\n{\n  \"vlm\": {\n    \"provider\": \"volcengine\",\n    \"model\": \"doubao-seed-2-0-pro-260215\",\n    \"api_key\": \"your-api-key\",\n    \"api_base\": \"https://ark.cn-beijing.volces.com/api/v3\"\n  }\n}\n```\n\nYou can also use endpoint IDs (found in [Volcengine ARK Console](https://console.volcengine.com/ark/region:ark+cn-beijing/overview?briefPage=0&briefType=introduce&type=new&utm_content=OpenViking&utm_medium=devrel&utm_source=OWO&utm_term=OpenViking):\n\n```json\n{\n  \"vlm\": {\n    \"provider\": \"volcengine\",\n    \"model\": \"ep-20241220174930-xxxxx\",\n    \"api_key\": \"your-api-key\",\n    \"api_base\": \"https://ark.cn-beijing.volces.com/api/v3\"\n  }\n}\n```\n\n</details>\n\n<details>\n<summary><b>OpenAI</b></summary>\n\nUse OpenAI's official API:\n\n```json\n{\n  \"vlm\": {\n    \"provider\": \"openai\",\n    \"model\": \"gpt-4o\",\n    \"api_key\": \"your-api-key\",\n    \"api_base\": \"https://api.openai.com/v1\"\n  }\n}\n```\n\nYou can also use a custom OpenAI-compatible endpoint:\n\n```json\n{\n  \"vlm\": {\n    \"provider\": \"openai\",\n    \"model\": \"gpt-4o\",\n    \"api_key\": \"your-api-key\",\n    \"api_base\": \"https://your-custom-endpoint.com/v1\"\n  }\n}\n```\n\n</details>\n\n<details>\n<summary><b>LiteLLM (Anthropic, DeepSeek, Gemini, Qwen, vLLM, Ollama, etc.)</b></summary>\n\nLiteLLM provides unified access to various models. The `model` field should follow LiteLLM's naming convention. Here we use Claude and Qwen as examples:\n\n**Anthropic:**\n\n```json\n{\n  \"vlm\": {\n    \"provider\": \"litellm\",\n    \"model\": \"claude-3-5-sonnet-20240620\",\n    \"api_key\": \"your-anthropic-api-key\"\n  }\n}\n```\n\n**Qwen (DashScope):**\n\n```json\n{\n  \"vlm\": {\n    \"provider\": \"litellm\",\n    \"model\": \"dashscope/qwen-turbo\", // see https://docs.litellm.ai/docs/providers/dashscope for more details\n    \"api_key\": \"your-dashscope-api-key\",\n    \"api_base\": \"https://dashscope.aliyuncs.com/compatible-mode/v1\"\n  }\n}\n```\n\n> 💡 **Tip for Qwen**: \n> - For **China/Beijing** region, use `api_base`: `https://dashscope.aliyuncs.com/compatible-mode/v1`\n> - For **International** region, use `api_base`: `https://dashscope-intl.aliyuncs.com/compatible-mode/v1`\n\n**Common model formats:**\n\n| Provider | Model Example | Notes |\n|----------|---------------|-------|\n| Anthropic | `claude-3-5-sonnet-20240620` | Auto-detected, uses `ANTHROPIC_API_KEY` |\n| DeepSeek | `deepseek-chat` | Auto-detected, uses `DEEPSEEK_API_KEY` |\n| Gemini | `gemini-pro` | Auto-detected, uses `GEMINI_API_KEY` |\n| Qwen | `dashscope/qwen-turbo` | Set `api_base` based on region (see above) |\n| OpenRouter | `openrouter/openai/gpt-4o` | Full prefix required |\n| vLLM | `hosted_vllm/llama-3.1-8b` | Set `api_base` to vLLM server |\n| Ollama | `ollama/llama3.1` | Set `api_base` to Ollama server |\n\n**Local Models (vLLM / Ollama):**\n\n```bash\n\n# Start Ollama\nollama serve\n```\n\n```json\n// Ollama\n{\n  \"vlm\": {\n    \"provider\": \"litellm\",\n    \"model\": \"ollama/llama3.1\",\n    \"api_base\": \"http://localhost:11434\"\n  }\n}\n```\n\nFor complete model support, see [LiteLLM Providers Documentation](https://docs.litellm.ai/docs/providers).\n\n</details>\n\n### 3. Environment Configuration\n\n#### Server Configuration Template\n\nCreate a configuration file `~/.openviking/ov.conf`, remove the comments before copy:\n\n```json\n{\n  \"storage\": {\n    \"workspace\": \"/home/your-name/openviking_workspace\"\n  },\n  \"log\": {\n    \"level\": \"INFO\",\n    \"output\": \"stdout\"                 // Log output: \"stdout\" or \"file\"\n  },\n  \"embedding\": {\n    \"dense\": {\n      \"api_base\" : \"<api-endpoint>\",   // API endpoint address\n      \"api_key\"  : \"<your-api-key>\",   // Model service API Key\n      \"provider\" : \"<provider-type>\",  // Provider type: \"volcengine\" or \"openai\" (currently supported)\n      \"dimension\": 1024,               // Vector dimension\n      \"model\"    : \"<model-name>\"      // Embedding model name (e.g., doubao-embedding-vision-250615 or text-embedding-3-large)\n    },\n    \"max_concurrent\": 10               // Max concurrent embedding requests (default: 10)\n  },\n  \"vlm\": {\n    \"api_base\" : \"<api-endpoint>\",     // API endpoint address\n    \"api_key\"  : \"<your-api-key>\",     // Model service API Key\n    \"provider\" : \"<provider-type>\",    // Provider type (volcengine, openai, deepseek, anthropic, etc.)\n    \"model\"    : \"<model-name>\",       // VLM model name (e.g., doubao-seed-2-0-pro-260215 or gpt-4-vision-preview)\n    \"max_concurrent\": 100              // Max concurrent LLM calls for semantic processing (default: 100)\n  }\n}\n```\n\n> **Note**: For embedding models, currently `volcengine` (Doubao), `openai`, and `jina` providers are supported. For VLM models, we support three providers: `volcengine`, `openai`, and `litellm`. The `litellm` provider supports various models including Anthropic (Claude), DeepSeek, Gemini, Moonshot, Zhipu, DashScope, MiniMax, vLLM, Ollama, and more.\n\n#### Server Configuration Examples\n\n👇 Expand to see the configuration example for your model service:\n\n<details>\n<summary><b>Example 1: Using Volcengine (Doubao Models)</b></summary>\n\n```json\n{\n  \"storage\": {\n    \"workspace\": \"/home/your-name/openviking_workspace\"\n  },\n  \"log\": {\n    \"level\": \"INFO\",\n    \"output\": \"stdout\"                 // Log output: \"stdout\" or \"file\"\n  },\n  \"embedding\": {\n    \"dense\": {\n      \"api_base\" : \"https://ark.cn-beijing.volces.com/api/v3\",\n      \"api_key\"  : \"your-volcengine-api-key\",\n      \"provider\" : \"volcengine\",\n      \"dimension\": 1024,\n      \"model\"    : \"doubao-embedding-vision-250615\"\n    },\n    \"max_concurrent\": 10\n  },\n  \"vlm\": {\n    \"api_base\" : \"https://ark.cn-beijing.volces.com/api/v3\",\n    \"api_key\"  : \"your-volcengine-api-key\",\n    \"provider\" : \"volcengine\",\n    \"model\"    : \"doubao-seed-2-0-pro-260215\",\n    \"max_concurrent\": 100\n  }\n}\n```\n\n</details>\n\n<details>\n<summary><b>Example 2: Using OpenAI Models</b></summary>\n\n```json\n{\n  \"storage\": {\n    \"workspace\": \"/home/your-name/openviking_workspace\"\n  },\n  \"log\": {\n    \"level\": \"INFO\",\n    \"output\": \"stdout\"                 // Log output: \"stdout\" or \"file\"\n  },\n  \"embedding\": {\n    \"dense\": {\n      \"api_base\" : \"https://api.openai.com/v1\",\n      \"api_key\"  : \"your-openai-api-key\",\n      \"provider\" : \"openai\",\n      \"dimension\": 3072,\n      \"model\"    : \"text-embedding-3-large\"\n    },\n    \"max_concurrent\": 10\n  },\n  \"vlm\": {\n    \"api_base\" : \"https://api.openai.com/v1\",\n    \"api_key\"  : \"your-openai-api-key\",\n    \"provider\" : \"openai\",\n    \"model\"    : \"gpt-4-vision-preview\",\n    \"max_concurrent\": 100\n  }\n}\n```\n\n</details>\n\n#### Set Server Configuration Environment Variable\n\nAfter creating the configuration file, set the environment variable to point to it (Linux/macOS):\n\n```bash\nexport OPENVIKING_CONFIG_FILE=~/.openviking/ov.conf # by default\n```\n\nOn Windows, use one of the following:\n\nPowerShell:\n\n```powershell\n$env:OPENVIKING_CONFIG_FILE = \"$HOME/.openviking/ov.conf\"\n```\n\nCommand Prompt (cmd.exe):\n\n```bat\nset \"OPENVIKING_CONFIG_FILE=%USERPROFILE%\\.openviking\\ov.conf\"\n```\n\n> 💡 **Tip**: You can also place the configuration file in other locations, just specify the correct path in the environment variable.\n\n#### CLI/Client Configuration Examples\n\n👇 Expand to see the configuration example for your CLI/Client:\n\nExample: ovcli.conf for visiting localhost server\n\n```json\n{\n  \"url\": \"http://localhost:1933\",\n  \"timeout\": 60.0,\n  \"output\": \"table\"\n}\n```\n\nAfter creating the configuration file, set the environment variable to point to it (Linux/macOS):\n\n```bash\nexport OPENVIKING_CLI_CONFIG_FILE=~/.openviking/ovcli.conf # by default\n```\n\nOn Windows, use one of the following:\n\nPowerShell:\n\n```powershell\n$env:OPENVIKING_CLI_CONFIG_FILE = \"$HOME/.openviking/ovcli.conf\"\n```\n\nCommand Prompt (cmd.exe):\n\n```bat\nset \"OPENVIKING_CLI_CONFIG_FILE=%USERPROFILE%\\.openviking\\ovcli.conf\"\n```\n\n### 4.

We have prepared a detailed step-by-step guide to get you started quickly.\n\n👉 **[View: Server Deployment & ECS Setup Guide](./docs/en/getting-started/03-quickstart-server.md)**\n\n\n## OpenClaw Context Plugin Details\n\n* Test Dataset: Effect testing based on LoCoMo10 (https://github.com/snap-research/locomo) long-range dialogues (1,540 cases in total after removing category5 without ground truth)\n* Experimental Groups: Since users may not disable OpenClaw's native memory when using OpenViking, we added experimental groups with native memory enabled or disabled\n* OpenViking Version: 0.1.18\n* Model: seed-2.0-code\n* Evaluation Script: https://github.com/ZaynJarvis/openclaw-eval/tree/main\n\n| Experimental Group | Task Completion Rate | Cost: Input Tokens (Total) |\n|----------|------------------|------------------|\n| OpenClaw(memory-core) |\t35.65% |\t24,611,530 |\n| OpenClaw + LanceDB (-memory-core) |\t44.55% |\t51,574,530 |\n| OpenClaw + OpenViking Plugin (-memory-core) |\t52.08% |\t4,264,396 |\n| OpenClaw + OpenViking Plugin (+memory-core) |\t51.23% |\t2,099,622 |\n\n* Experimental Conclusions:\nAfter integrating OpenViking:\n- With native memory enabled: 43% improvement over original OpenClaw with 91% reduction in input token cost; 15% improvement over LanceDB with 96% reduction in input token cost.\n- With native memory disabled: 49% improvement over original OpenClaw with 83% reduction in input token cost; 17% improvement over LanceDB with 92% reduction in input token cost.\n\n👉 **[View: OpenClaw Context Plugin](examples/openclaw-plugin/README.md)**\n\n👉 **[View: OpenCode Memory Plugin Example](examples/opencode-memory-plugin/README.md)**\n\n--\n\n## Core Concepts\n\nAfter running the first example, let's dive into the design philosophy of OpenViking. These five core concepts correspond one-to-one with the solutions mentioned earlier, together building a complete context management system:\n\n### 1. Filesystem Management Paradigm → Solves Fragmentation\n\nWe no longer view context as flat text slices but unify them into an abstract virtual filesystem. Whether it's memories, resources, or capabilities, they are mapped to virtual directories under the `viking://` protocol, each with a unique URI.\n\nThis paradigm gives Agents unprecedented context manipulation capabilities, enabling them to locate, browse, and manipulate information precisely and deterministically through standard commands like `ls` and `find`, just like a developer. This transforms context management from vague semantic matching into intuitive, traceable \"file operations\". Learn more: [Viking URI](./docs/en/concepts/04-viking-uri.md) | [Context Types](./docs/en/concepts/02-context-types.md)\n\n```\nviking://\n├── resources/              # Resources: project docs, repos, web pages, etc.\n│   ├── my_project/\n│   │   ├── docs/\n│   │   │   ├── api/\n│   │   │   └── tutorials/\n│   │   └── src/\n│   └── ...\n├── user/                   # User: personal preferences, habits, etc.\n│   └── memories/\n│       ├── preferences/\n│       │   ├── writing_style\n│       │   └── coding_habits\n│       └── ...\n└── agent/                  # Agent: skills, instructions, task memories, etc.\n    ├── skills/\n    │   ├── search_code\n    │   ├── analyze_data\n    │   └── ...\n    ├── memories/\n    └── instructions/\n```\n\n### 2. Tiered Context Loading → Reduces Token Consumption\n\nStuffing massive amounts of context into a prompt all at once is not only expensive but also prone to exceeding model windows and introducing noise. OpenViking automatically processes context into three levels upon writing:\n- **L0 (Abstract)**: A one-sentence summary for quick retrieval and identification.\n- **L1 (Overview)**: Contains core information and usage scenarios for Agent decision-making during the planning phase.\n- **L2 (Details)**: The full original data, for deep reading by the Agent when absolutely necessary.\n\nLearn more: [Context Layers](./docs/en/concepts/03-context-layers.md)\n\n```\nviking://resources/my_project/\n├── .abstract               # L0 Layer: Abstract (~100 tokens) - Quick relevance check\n├── .overview               # L1 Layer: Overview (~2k tokens) - Understand structure and key points\n├── docs/\n│   ├── .abstract          # Each directory has corresponding L0/L1 layers\n│   ├── .overview\n│   ├── api/\n│   │   ├── .abstract\n│   │   ├── .overview\n│   │   ├── auth.md        # L2 Layer: Full content - Load on demand\n│   │   └── endpoints.md\n│   └── ...\n└── src/\n    └── ...\n```\n\n### 3. Directory Recursive Retrieval → Improves Retrieval Effect\n\nSingle vector retrieval struggles with complex query intents. OpenViking has designed an innovative **Directory Recursive Retrieval Strategy** that deeply integrates multiple retrieval methods:\n\n1. **Intent Analysis**: Generate multiple retrieval conditions through intent analysis.\n2. **Initial Positioning**: Use vector retrieval to quickly locate the high-score directory where the initial slice is located.\n3. **Refined Exploration**: Perform a secondary retrieval within that directory and update high-score results to the candidate set.\n4. **Recursive Drill-down**: If subdirectories exist, recursively repeat the secondary retrieval steps layer by layer.\n5. **Result Aggregation**: Finally, obtain the most relevant context to return.\n\nThis \"lock high-score directory first, then refine content exploration\" strategy not only finds the semantically best-matching fragments but also understands the full context where the information resides, thereby improving the globality and accuracy of retrieval. Learn more: [Retrieval Mechanism](./docs/en/concepts/07-retrieval.md)\n\n### 4. Visualized Retrieval Trajectory → Observable Context\n\nOpenViking's organization uses a hierarchical virtual filesystem structure. All context is integrated in a unified format, and each entry corresponds to a unique URI (like a `viking://` path), breaking the traditional flat black-box management mode with a clear hierarchy that is easy to understand.\n\nThe retrieval process adopts a directory recursive strategy. The trajectory of directory browsing and file positioning for each retrieval is fully preserved, allowing users to clearly observe the root cause of problems and guide the optimization of retrieval logic.

At the end of each session, developers can actively trigger the memory extraction mechanism. The system will asynchronously analyze task execution results and user feedback, and automatically update them to the User and Agent memory directories.\n\n- **User Memory Update**: Update memories related to user preferences, making Agent responses better fit user needs.\n- **Agent Experience Accumulation**: Extract core content such as operational tips and tool usage experience from task execution experience, aiding efficient decision-making in subsequent tasks.\n\nThis allows the Agent to get \"smarter with use\" through interactions with the world, achieving self-evolution.

智能体时，开发者经常面临以下挑战：\n\n- **上下文碎片化**：记忆存储在代码中，资源在向量数据库中，技能分散在各处，难以统一管理。\n- **上下文需求激增**：智能体的长运行任务在每次执行时都会产生上下文。简单的截断或压缩会导致信息丢失。\n- **检索效果不佳**：传统 RAG 使用扁平化存储，缺乏全局视图，难以理解信息的完整上下文。\n- **上下文不可观察**：传统 RAG 的隐式检索链像黑盒，出错时难以调试。\n- **记忆迭代有限**：当前记忆只是用户交互的记录，缺乏智能体相关的任务记忆。\n\n### OpenViking 解决方案\n\n**OpenViking** 是专为 AI 智能体设计的开源**上下文数据库**。\n\n我们的目标是为智能体定义一个极简的上下文交互范式，让开发者完全告别上下文管理的烦恼。OpenViking 抛弃了传统 RAG 的碎片化向量存储模型，创新性地采用 **\"文件系统范式\"** 来统一组织智能体所需的记忆、资源和技能。\n\n使用 OpenViking，开发者可以像管理本地文件一样构建智能体的大脑：\n\n- **文件系统管理范式** → **解决碎片化**：基于文件系统范式统一管理记忆、资源和技能。\n- **分层上下文加载** → **降低 Token 消耗**：L0/L1/L2 三层结构，按需加载，显著节省成本。\n- **目录递归检索** → **提升检索效果**：支持原生文件系统检索方式，结合目录定位和语义搜索，实现递归精准的上下文获取。\n- **可视化检索轨迹** → **可观察上下文**：支持目录检索轨迹可视化，让用户清晰观察问题根源，指导检索逻辑优化。\n- **自动会话管理** → **上下文自迭代**：自动压缩对话中的内容、资源引用、工具调用等，提取长期记忆，让智能体越用越聪明。\n\n---\n\n## 快速开始\n\n### 前置条件\n\n在开始使用 OpenViking 之前，请确保您的环境满足以下要求：\n\n- **Python 版本**：3.10 或更高版本\n- **Go 版本**：1.22 或更高（从源码构建 AGFS 组件需要）\n- **C++ 编译器**：GCC 9+ 或 Clang 11+（构建核心扩展需要，必须支持 C++17）\n- **操作系统**：Linux、macOS、Windows\n- **网络连接**：需要稳定的网络连接（用于下载依赖和访问模型服务）\n\n### 1. 安装\n\n#### Python 包\n\n```bash\npip install openviking --upgrade

核心概念\n\n运行第一个示例后，让我们深入了解 OpenViking 的设计理念。这五个核心概念与前面提到的解决方案一一对应，共同构建了一个完整的上下文管理系统：\n\n### 1. 文件系统管理范式 → 解决碎片化\n\n我们不再将上下文视为扁平的文本切片，而是将它们统一到一个抽象的虚拟文件系统中。无论是记忆、资源还是能力，都映射到 `viking://` 协议下的虚拟目录中，每个都有唯一的 URI。\n\n这种范式赋予智能体前所未有的上下文操作能力，使它们能够像开发者一样，通过 `ls` 和 `find` 等标准命令精确、确定地定位、浏览和操作信息。这将上下文管理从模糊的语义匹配转变为直观、可追踪的\"文件操作\"。了解更多：[Viking URI](./docs/en/concepts/04-viking-uri.md) | [上下文类型](./docs/en/concepts/02-context-types.md)\n\n```\nviking://\n├── resources/              # 资源：项目文档、代码库、网页等\n│   ├── my_project/\n│   │   ├── docs/\n│   │   │   ├── api/\n│   │   │   └──

分层上下文加载 → 降低 Token 消耗\n\n一次性将大量上下文塞入提示不仅昂贵，而且容易超出模型窗口并引入噪声。OpenViking 在写入时自动将上下文处理为三个级别：\n- **L0 (摘要)**：一句话摘要，用于快速检索和识别。\n- **L1 (概览)**：包含核心信息和使用场景，用于智能体在规划阶段的决策。\n- **L2 (详情)**：完整的原始数据，供智能体在绝对必要时深度阅读。\n\n了解更多：[上下文分层](./docs/en/concepts/03-context-layers.md)\n\n```\nviking://resources/my_project/\n├── .abstract               # L0 层：摘要（~100 tokens）- 快速相关性检查\n├── .overview               # L1 层：概览（~2k tokens）- 理解结构和关键点\n├── docs/\n│   ├── .abstract          # 每个目录都有对应的 L0/L1 层\n│   ├── .overview\n│   ├── api/\n│   │   ├── .abstract\n│   │   ├── .overview\n│   │   ├── auth.md        # L2 层：完整内容 - 按需加载\n│   │   └── endpoints.md\n│   └── ...\n└── src/\n    └── ...\n```\n\n### 3. 目录递归检索 → 提升检索效果\n\n单一向量检索难以应对复杂的查询意图。OpenViking 设计了创新的**目录递归检索策略**，深度集成多种检索方法：\n\n1. **意图分析**：通过意图分析生成多个检索条件。\n2. **初始定位**：使用向量检索快速定位初始切片所在的高分目录。\n3. **精细探索**：在该目录内进行二次检索，并将高分结果更新到候选集。\n4. **递归深入**：如果存在子目录，则逐层递归重复二次检索步骤。\n5. **结果聚合**：最终获取最相关的上下文返回。\n\n这种\"先锁定高分目录，再精细化内容探索\"的策略不仅找到语义最佳匹配的片段，还能理解信息所在的完整上下文，从而提高检索的全局性和准确性。了解更多：[检索机制](./docs/en/concepts/07-retrieval.md)\n\n### 4. 可视化检索轨迹 → 可观察上下文\n\nOpenViking 的组织采用分层虚拟文件系统结构。所有上下文以统一格式集成，每个条目对应一个唯一的 URI（如 `viking://` 路径），打破了传统的扁平黑盒管理模式，具有清晰易懂的层次结构。\n\n检索过程采用目录递归策略。每次检索的目录浏览和文件定位轨迹被完整保留，让用户能够清晰观察问题的根源，指导检索逻辑的优化。了解更多：[检索机制](./docs/en/concepts/07-retrieval.md)\n\n### 5. 自动会话管理 → 上下文自迭代\n\nOpenViking 内置了记忆自迭代循环。在每个会话结束时，开发者可以主动触发记忆提取机制。系统将异步分析任务执行结果和用户反馈，并自动更新到用户和智能体记忆目录。\n\n- **用户记忆更新**：更新与用户偏好相关的记忆，使智能体响应更好地适应用户需求。\n- **智能体经验积累**：从任务执行经验中提取操作技巧和工具使用经验等核心内容，辅助后续任务的高效决策。\n\n这使得智能体能够通过与世界的交互\"越用越聪明\"，实现自我进化。了解更多：[会话管理](./docs/en/concepts/08-session.md)\n\n---\n\n## 深入阅读\n\n###

概要\n\n### エージェント開発における課題\n\nAI時代において、データは豊富ですが、高品質なコンテキストは得がたいものです。AIエージェントを構築する際、開発者はしばしば以下の課題に直面します：\n\n- **断片化されたコンテキスト**: メモリはコードに、リソースはベクトルデータベースに、スキルは散在しており、統一的な管理が困難です。\n- **急増するコンテキスト需要**: エージェントの長時間タスクは実行のたびにコンテキストを生成します。単純な切り詰めや圧縮は情報の損失につながります。\n- **検索効果の低さ**: 従来のRAGはフラットなストレージを使用し、グローバルな視点が欠けているため、情報の全体的なコンテキストを理解することが困難です。\n- **観察不能なコンテキスト**: 従来のRAGの暗黙的な検索チェーンはブラックボックスのようで、エラー発生時のデバッグが困難です。\n- **限定的なメモリの反復**: 現在のメモリはユーザーとのやり取りの記録に過ぎず、エージェント関連のタスクメモリが不足しています。\n\n### OpenVikingのソリューション\n\n**OpenViking**は、AIエージェント専用に設計されたオープンソースの**コンテキストデータベース**です。\n\n私たちは、エージェントのためのミニマリストなコンテキストインタラクションパラダイムを定義し、開発者がコンテキスト管理の煩雑さから完全に解放されることを目指しています。OpenVikingは従来のRAGの断片化されたベクトルストレージモデルを捨て、革新的に**「ファイルシステムパラダイム」**を採用して、エージェントに必要なメモリ、リソース、スキルの構造化された組織を統一します。\n\nOpenVikingを使えば、開発者はローカルファイルを管理するようにエージェントの頭脳を構築できます：\n\n- **ファイルシステム管理パラダイム** → **断片化を解決**: ファイルシステムパラダイムに基づく、メモリ、リソース、スキルの統一的なコンテキスト管理。\n- **階層型コンテキストローディング** → **トークン消費を削減**: L0/L1/L2の3層構造、オンデマンドでロードし、コストを大幅に削減。\n- **ディレクトリ再帰検索** → **検索効果を向上**: ネイティブのファイルシステム検索手法をサポートし、ディレクトリ位置決めとセマンティック検索を組み合わせて、再帰的で精密なコンテキスト取得を実現。\n- **可視化された検索軌跡** → **観察可能なコンテキスト**: ディレクトリ検索軌跡の可視化をサポートし、ユーザーが問題の根本原因を明確に観察し、検索ロジックの最適化を導くことを可能に。\n- **自動セッション管理** → **コンテキストの自己反復**: 会話中のコンテンツ、リソース参照、ツール呼び出しなどを自動的に圧縮し、長期メモリを抽出して、使うほどエージェントを賢く。\n\n---\n\n## クイックスタート\n\n### 前提条件\n\nOpenVikingを始める前に、環境が以下の要件を満たしていることを確認してください：\n\n- **Pythonバージョン**: 3.10以上\n- **Goバージョン**: 1.22以上（AGFSコンポーネントのビルドに必要）\n- **C++コンパイラ**: GCC 9以上 または Clang 11以上（コア拡張のビルドに必要）\n- **オペレーティングシステム**: Linux、macOS、Windows\n- **ネットワーク接続**:

ファイルシステム管理パラダイム → 断片化の解決\n\nコンテキストをフラットなテキストスライスとして見るのではなく、抽象的な仮想ファイルシステムに統一します。メモリ、リソース、機能のいずれも、`viking://`プロトコル下の仮想ディレクトリにマッピングされ、それぞれにユニークなURIが付与されます。\n\nこのパラダイムにより、エージェントはこれまでにないコンテキスト操作能力を獲得し、開発者のように`ls`や`find`などの標準コマンドを通じて、情報を正確かつ決定論的に位置特定、閲覧、操作できます。これにより、コンテキスト管理は曖昧なセマンティックマッチングから、直感的でトレース可能な「ファイル操作」に変わります。詳細: [Viking URI](./docs/en/concepts/04-viking-uri.md) | [コンテキストタイプ](./docs/en/concepts/02-context-types.md)\n\n```\nviking://\n├── resources/              # リソース: プロジェクトドキュメント、リポジトリ、Webページなど\n│   ├── my_project/\n│   │   ├── docs/\n│   │   │   ├── api/\n│   │   │   └── tutorials/\n│   │   └── src/\n│   └── ...\n├── user/                   # ユーザー: 個人の好み、習慣など\n│   └── memories/\n│       ├──

│   ├── analyze_data\n    │   └── ...\n    ├── memories/\n    └── instructions/\n```\n\n### 2. 階層型コンテキストローディング → トークン消費の削減\n\n大量のコンテキストをプロンプトに一度に詰め込むことは、コストが高いだけでなく、モデルウィンドウの超過やノイズの混入を招きやすいです。OpenVikingは書き込み時にコンテキストを自動的に3つのレベルに処理します：\n- **L0（Abstract）**: 迅速な検索と識別のための一文の要約。\n- **L1（Overview）**: 計画フェーズでのエージェントの意思決定のための、コア情報と使用シナリオを含む。\n- **L2（Details）**: エージェントが絶対に必要な場合の深い読み込みのための、完全なオリジナルデータ。\n\n詳細: [コンテキストレイヤー](./docs/en/concepts/03-context-layers.md)\n\n```\nviking://resources/my_project/\n├── .abstract               # L0レイヤー: 要約（〜100トークン）- 迅速な関連性チェック\n├── .overview               # L1レイヤー: 概要（〜2kトークン）- 構造とキーポイントの理解\n├── docs/\n│   ├── .abstract          # 各ディレクトリに対応するL0/L1レイヤーあり\n│   ├── .overview\n│   ├── api/\n│   │   ├── .abstract\n│   │   ├── .overview\n│   │   ├── auth.md        # L2レイヤー: 完全なコンテンツ - オンデマンドでロード\n│   │   └── endpoints.md\n│   └── ...\n└── src/\n    └── ...\n```\n\n### 3. ディレクトリ再帰検索 → 検索効果の向上\n\n単一のベクトル検索では、複雑なクエリインテントへの対応が困難です。OpenVikingは、複数の検索手法を深く統合する革新的な**ディレクトリ再帰検索戦略**を設計しました：\n\n1. **インテント分析**: インテント分析により複数の検索条件を生成。\n2. **初期位置特定**: ベクトル検索を使用して、初期スライスが位置する高スコアディレクトリを素早く特定。\n3. **詳細な探索**: そのディレクトリ内で二次検索を実行し、高スコア結果を候補セットに更新。\n4. **再帰的掘り下げ**: サブディレクトリが存在する場合、二次検索ステップを層ごとに再帰的に繰り返し。\n5. **結果集約**: 最終的に、最も関連性の高いコンテキストを取得して返却。\n\nこの「まず高スコアディレクトリを特定し、次にコンテンツ探索を精緻化する」戦略は、セマンティック的に最もマッチするフラグメントを見つけるだけでなく、情報が存在するコンテキスト全体を理解し、検索のグローバル性と精度を向上させます。詳細: [検索メカニズム](./docs/en/concepts/07-retrieval.md)\n\n### 4. 可視化された検索軌跡 → 観察可能なコンテキスト\n\nOpenVikingの組織は階層的な仮想ファイルシステム構造を使用しています。すべてのコンテキストは統一されたフォーマットで統合され、各エントリはユニークなURI（`viking://`パスのようなもの）に対応し、従来のフラットなブラックボックス管理モードを、理解しやすい明確な階層で打ち破ります。\n\n検索プロセスはディレクトリ再帰戦略を採用しています。各検索のディレクトリブラウジングとファイル位置特定の軌跡が完全に保存され、ユーザーが問題の根本原因を明確に観察し、検索ロジックの最適化を導くことを可能にします。詳細: [検索メカニズム](./docs/en/concepts/07-retrieval.md)\n\n### 5. 自動セッション管理 → コンテキストの自己反復\n\nOpenVikingにはメモリ自己反復ループが組み込まれています。各セッションの終了時に、開発者はメモリ抽出メカニズムを能動的にトリガーできます。システムはタスク実行結果とユーザーフィードバックを非同期的に分析し、ユーザーとエージェントのメモリディレクトリに自動的に更新します。\n\n- **ユーザーメモリの更新**: ユーザーの好みに関するメモリを更新し、エージェントの応答がユーザーのニーズにより適合するように。\n- **エージェントの経験蓄積**: タスク実行経験から操作のヒントやツールの使用経験などのコアコンテンツを抽出し、後続タスクでの効率的な意思決定を支援。\n\nこれにより、エージェントは世界とのインタラクションを通じて「使うほど賢く」なり、自己進化を実現します。詳細: [セッション管理](./docs/en/concepts/08-session.md)\n\n---\n\n## 上級者向け資料\n\n### ドキュメント\n\n詳細については、[完全なドキュメント](./docs/en/)をご覧ください。\n\n###

Initialize configuration**\n\n```bash\nvikingbot gateway\n```\n\nThis will automatically:\n- Create a default config at `~/.openviking/ov.conf`\n- Create bot startup files in the OpenViking workspace, default path is `~/.openviking/data/bot/`\n\n**2. Configure via ov.conf**\n\nEdit `~/.openviking/ov.conf` to add your provider API keys (OpenRouter, OpenAI, etc.) and save the config.\n\n**3. Chat**\n\n```bash\n# Send a single message directly\nvikingbot chat -m \"What is 2+2?\"\n\n# Enter interactive chat mode (supports multi-turn conversations)\nvikingbot chat\n\n# Show plain-text replies (no Markdown rendering)\nvikingbot chat --no-markdown\n\n# Show runtime logs during chat (useful for debugging)\nvikingbot chat --logs\n```\n\nThat's it! You have a working AI assistant in 2 minutes.\n\nTalk to your vikingbot through Telegram, Discord, WhatsApp, Feishu, Mochat, DingTalk, Slack, Email, or QQ — anytime, anywhere.\n\nFor detailed configuration, please refer to [CHANNEL.md](bot/docs/CHANNEL.md).\n\n## 🌐 Agent Social Network\n\n🐈 vikingbot is capable of linking to the agent social network (agent community). **Just send one message and your vikingbot joins automatically!**\n\n| Platform | How to Join (send this message to your bot) |\n|----------|-------------|\n| [**Moltbook**](https://www.moltbook.com/) | `Read https://moltbook.com/skill.md and follow the instructions to join Moltbook` |\n| [**ClawdChat**](https://clawdchat.ai/) | `Read https://clawdchat.ai/skill.md and follow the instructions to join ClawdChat` |\n\nSimply send the command above to your vikingbot (via CLI or any chat channel), and it will handle the rest.\n\n## ⚙️ Configuration\n\nConfig file: `~/.openviking/ov.conf` (custom path can be set via environment variable `OPENVIKING_CONFIG_FILE`)\n\n> [!TIP]\n> Vikingbot shares the same configuration file with OpenViking. Configuration items are located under the `bot` field of the file, and will automatically merge global configurations such as `vlm`, `storage`, `server`, etc. No need to maintain a separate configuration file.\n\n> [!IMPORTANT]\n> After modifying the configuration (by editing the file directly),\n> you need to restart the gateway service for changes to take effect.\n\n### OpenViking Server Configuration\nThe bot will connect to the remote OpenViking server. Please start the OpenViking Server before use. By default, the OpenViking server information configured in `ov.conf` is used\n- OpenViking default startup address is 127.0.0.1:1933\n- If `root_api_key` is configured, multi-tenant mode is enabled.

# 用于自动匹配的模型名称关键词\n    env_key=\"MYPROVIDER_API_KEY\",        # LiteLLM 的环境变量\n    display_name=\"My Provider\",          # 在 `vikingbot status` 中显示\n    litellm_prefix=\"myprovider\",         # 自动前缀：模型 → myprovider/model\n    skip_prefixes=(\"myprovider/\",),      # 不要双重前缀\n)\n```\n\n**步骤 2.** 在 `vikingbot/config/schema.py` 的 `ProvidersConfig` 中添加一个字段：\n\n```python\nclass ProvidersConfig(BaseModel):\n    ...\n    myprovider: ProviderConfig = ProviderConfig()\n```\n\n就这么简单！环境变量、模型前缀、配置匹配和 `vikingbot status` 显示都将自动工作。\n\n**常见的 `ProviderSpec` 选项：**\n\n| 字段 | 描述 | 示例 |\n|-------|-------------|---------|\n| `litellm_prefix` | 为 LiteLLM 自动前缀模型名称 | `\"dashscope\"` → `dashscope/qwen-max` |\n| `skip_prefixes` | 如果模型已经以这些开头，则不要前缀 | `(\"dashscope/\", \"openrouter/\")` |\n| `env_extras` | 要设置的额外环境变量 | `((\"ZHIPUAI_API_KEY\", \"{api_key}\"),)` |\n| `model_overrides` | 每模型参数覆盖 | `((\"kimi-k2.5\", {\"temperature\": 1.0}),)` |\n| `is_gateway` | 可以路由任何模型（如 OpenRouter） | `True` |\n| `detect_by_key_prefix` | 通过 API 密钥前缀检测网关 | `\"sk-or-\"` |\n| `detect_by_base_keyword` | 通过 API 基础 URL 检测网关 | `\"openrouter\"` |\n| `strip_model_prefix` | 在重新前缀之前去除现有前缀 | `True`（对于 AiHubMix） |\n\n</details>\n\n\n### 可观测性（可选）\n\n**Langfuse** 集成，用于 LLM 可观测性和追踪。\n\n<details>\n<summary><b>Langfuse 配置</b></summary>\n\n**方式 1：本地部署（测试推荐）**\n\n使用 Docker 在本地部署 Langfuse：\n\n```bash\n# 进入部署脚本目录\ncd deploy/docker\n\n# 运行部署脚本\n./deploy_langfuse.sh\n```\n\n这将在 `http://localhost:3000` 启动 Langfuse，并使用预配置的凭据。\n\n**方式 2：Langfuse Cloud**\n\n1. 在 [langfuse.com](https://langfuse.com) 注册\n2. 创建新项目\n3. 从项目设置中复制 **Secret Key** 和 **Public Key**\n\n**配置**\n\n添加到 `~/.openviking/ov.conf`：\n\n```json\n{\n  \"bot\": {\n    \"langfuse\": {\n      \"enabled\": true,\n      \"secret_key\": \"sk-lf-vikingbot-secret-key-2026\",\n      \"public_key\": \"pk-lf-vikingbot-public-key-2026\",\n      \"base_url\": \"http://localhost:3000\"\n    }\n  }\n}\n```\n\n对于 Langfuse Cloud，使用 `https://cloud.langfuse.com` 作为 `base_url`。\n\n**安装 Langfuse 支持：**\n```bash\nuv pip install -e \".[bot-langfuse]\"\n```\n\n**重启 vikingbot：**\n```bash\nvikingbot gateway\n```\n\n**启用的功能：**\n- 每次对话自动创建 trace\n- Session 和 User 追踪\n- LLM 调用监控\n- Token 使用量追踪\n\n</details>\n\n### 安全\n\n| 选项 | 默认值 | 描述 |\n|--------|---------|-------------|\n| `tools.restrictToWorkspace` | `true` | 当为 `true` 时，将**所有**代理工具（shell、文件读/写/编辑、列表）限制到工作区目录。防止路径遍历和范围外访问。 |\n| `channels.*.allowFrom` | `[]`（允许所有） | 用户 ID 白名单。空 = 允许所有人；非空 = 只有列出的用户可以交互。 |\n\n### 沙箱\n\nvikingbot 支持沙箱执行以增强安全性。\n\n**默认情况下，`ov.conf` 中不需要配置 sandbox：**\n- 默认后端：`direct`（直接在主机上运行代码）\n- 默认模式：`shared`（所有会话共享一个沙箱）\n\n只有当您想要更改这些默认值时，才需要添加 sandbox 配置。\n\n<details>\n<summary><b>沙箱配置选项</b></summary>\n\n**使用不同的后端或模式：**\n```json\n{\n  \"bot\": {\n    \"sandbox\": {\n      \"backend\": \"srt\",\n      \"mode\": \"per-session\"\n    }\n  }\n}\n```\n\n**可用后端：**\n| 后端 | 描述 |\n|---------|-------------|\n| `direct` | （默认）直接在主机上运行代码 |\n| `srt` | 使用 Anthropic 的 SRT 沙箱运行时 |\n\n**可用模式：**\n| 模式 | 描述 |\n|------|-------------|\n| `shared` | （默认）所有会话共享一个沙箱 |\n| `per-session` | 每个会话使用独立的沙箱实例 |\n\n**后端特定配置（仅在使用该后端时需要）：**\n\n**Direct 后端：**\n```json\n{\n  \"bot\": {\n    \"sandbox\": {\n      \"backends\": {\n        \"direct\": {\n          \"restrictToWorkspace\": false\n        }\n      }\n    }\n  }\n}\n```\n\n**SRT 后端：**\n```json\n{\n  \"bot\": {\n    \"sandbox\": {\n      \"backend\": \"srt\",\n      \"backends\": {\n        \"srt\": {\n          \"nodePath\": \"node\",\n          \"network\": {\n            \"allowedDomains\": [],\n            \"deniedDomains\": [],\n            \"allowLocalBinding\": false\n          },\n          \"filesystem\": {\n            \"denyRead\": [],\n            \"allowWrite\": [],\n            \"denyWrite\": []\n          },\n          \"runtime\": {\n            \"cleanupOnExit\": true,\n            \"timeout\": 300\n          }\n        }\n      }\n    }\n  }\n}\n```\n\n**SRT 后端设置：**\n\nSRT 后端使用 `@anthropic-ai/sandbox-runtime`。\n\n**系统依赖：**\n\nSRT 后端还需要安装这些系统包：\n- `ripgrep` (rg) - 用于文本搜索\n- `bubblewrap` (bwrap) - 用于沙箱隔离\n- `socat` - 用于网络代理\n\n**在 macOS 上安装：**\n```bash\nbrew install ripgrep bubblewrap socat\n```\n\n**在 Ubuntu/Debian 上安装：**\n```bash\nsudo apt-get install -y ripgrep bubblewrap socat\n```\n\n**在 Fedora/CentOS 上安装：**\n```bash\nsudo dnf install -y ripgrep bubblewrap socat\n```\n\n验证安装：\n\n```bash\nnpm list -g @anthropic-ai/sandbox-runtime\n```\n\n如果未安装，请手动安装：\n\n```bash\nnpm install -g @anthropic-ai/sandbox-runtime\n```\n\n**Node.js 路径配置：**\n\n如果在 PATH 中找不到 `node` 命令，请在您的配置中指定完整路径：\n\n```json\n{\n  \"bot\": {\n    \"sandbox\": {\n      \"backends\": {\n        \"srt\": {\n          \"nodePath\": \"/usr/local/bin/node\"\n        }\n      }\n    }\n  }\n}\n```\n\n查找您的 Node.js 路径：\n\n```bash\nwhich node\n# 或\nwhich nodejs\n```\n\n</details>\n\n\n## CLI 参考\n\n| 命令 | 描述 |\n|---------|-------------|\n| `vikingbot chat -m \"...\"`

    "path": "bot/SECURITY.md",
    "content": "# Security Policy\n\n## Reporting a Vulnerability\n\nIf you discover a security vulnerability in vikingbot, please report it by:\n\n1. **DO NOT** open a public GitHub issue\n2. Create a private security advisory on GitHub or contact the repository maintainers\n3. Include:\n   - Description of the vulnerability\n   - Steps to reproduce\n   - Potential impact\n   - Suggested fix (if any)\n\nWe aim to respond to security reports within 48 hours.\n\n## Security Best Practices\n\n### 1. API Key Management\n\n**CRITICAL**: Never commit API keys to version control.\n\n```bash\n# ✅ Good: Store in config file with restricted permissions\nchmod 600 ~/.vikingbot/config.json\n\n# ❌ Bad: Hardcoding keys in code or committing them\n```\n\n**Recommendations:**\n- Store API keys in `~/.vikingbot/config.json` with file permissions set to `0600`\n- Consider using environment variables for sensitive keys\n- Use OS keyring/credential manager for production deployments\n- Rotate API keys regularly\n- Use separate API keys for development and production\n\n### 2. Channel Access Control\n\n**IMPORTANT**: Always configure `allowFrom` lists for production use.\n\n```json\n{\n  \"channels\": {\n    \"telegram\": {\n      \"enabled\": true,\n      \"token\": \"YOUR_BOT_TOKEN\",\n      \"allowFrom\": [\"123456789\", \"987654321\"]\n    },\n    \"whatsapp\": {\n      \"enabled\": true,\n      \"allowFrom\": [\"+1234567890\"]\n    }\n  }\n}\n```\n\n**Security Notes:**\n- Empty `allowFrom` list will **ALLOW ALL** users (open by default for personal use)\n- Get your Telegram user ID from `@userinfobot`\n- Use full phone numbers with country code for WhatsApp\n- Review access logs regularly for unauthorized access attempts\n\n### 3. Shell Command Execution\n\nThe `exec` tool can execute shell commands. While dangerous command patterns are blocked, you should:\n\n- ✅ Review all tool usage in agent logs\n- ✅ Understand what commands the agent is running\n- ✅ Use a dedicated user account with limited privileges\n- ✅ Never run vikingbot as root\n- ❌ Don't disable security checks\n- ❌ Don't run on systems with sensitive data without careful review\n\n**Blocked patterns:**\n- `rm -rf /` - Root filesystem deletion\n- Fork bombs\n- Filesystem formatting (`mkfs.*`)\n- Raw disk writes\n- Other destructive operations\n\n### 4. File System Access\n\nFile operations have path traversal protection, but:\n\n- ✅ Run vikingbot with a dedicated user account\n- ✅ Use filesystem permissions to protect sensitive directories\n- ✅ Regularly audit file operations in logs\n- ❌ Don't give unrestricted access to sensitive files\n\n### 5. Network Security\n\n**API Calls:**\n- All external API calls use HTTPS by default\n- Timeouts are configured to prevent hanging requests\n- Consider using a firewall to restrict outbound connections if needed\n\n**WhatsApp Bridge:**\n- The bridge binds to `127.0.0.1:3001` (localhost only, not accessible from external network)\n- Set `bridgeToken` in config to enable shared-secret authentication between Python and Node.js\n- Keep authentication data in `~/.vikingbot/whatsapp-auth` secure (mode 0700)\n\n### 6. Dependency Security\n\n**Critical**: Keep dependencies updated!\n\n```bash\n# Check for vulnerable dependencies\npip install pip-audit\npip-audit\n\n# Update to latest secure versions\npip install --upgrade vikingbot-ai\n```\n\nFor Node.js dependencies (WhatsApp bridge):\n```bash\ncd bridge\nnpm audit\nnpm audit fix\n```\n\n**Important Notes:**\n- Keep `litellm` updated to the latest version for security fixes\n- We've updated `ws` to `>=8.17.1` to fix DoS vulnerability\n- Run `pip-audit` or `npm audit` regularly\n- Subscribe to security advisories for vikingbot and its dependencies\n\n### 7. Production Deployment\n\nFor production use:\n\n1. **Isolate the Environment**\n   ```bash\n   # Run in a container or VM\n   docker run --rm -it python:3.11\n   pip install vikingbot-ai\n   ```\n\n2. **Use a Dedicated User**\n   ```bash\n   sudo useradd -m -s /bin/bash vikingbot\n   sudo -u vikingbot vikingbot gateway\n   ```\n\n3. **Set Proper Permissions**\n   ```bash\n   chmod 700 ~/.vikingbot\n   chmod 600 ~/.vikingbot/config.json\n   chmod 700 ~/.vikingbot/whatsapp-auth\n   ```\n\n4. **Enable Logging**\n   ```bash\n   # Configure log monitoring\n   tail -f ~/.vikingbot/logs/vikingbot.log\n   ```\n\n5. **Use Rate Limiting**\n   - Configure rate limits on your API providers\n   - Monitor usage for anomalies\n   - Set spending limits on LLM APIs\n\n6. **Regular Updates**\n   ```bash\n   # Check for updates weekly\n   pip install --upgrade vikingbot-ai\n   ```\n\n### 8. Development vs Production\n\n**Development:**\n- Use separate API keys\n- Test with non-sensitive data\n- Enable verbose logging\n- Use a test Telegram bot\n\n**Production:**\n- Use dedicated API keys with spending limits\n- Restrict file system access\n- Enable audit logging\n- Regular security reviews\n- Monitor for unusual activity\n\n### 9. Data Privacy\n\n- **Logs may contain sensitive information** - secure log files appropriately\n- **LLM providers see your prompts** - review their privacy policies\n- **Chat history is stored locally** - protect the `~/.vikingbot` directory\n- **API keys are in plain text** - use OS keyring for production\n\n### 10. Incident Response\n\nIf you suspect a security breach:\n\n1. **Immediately revoke compromised API keys**\n2. **Review logs for unauthorized access**\n   ```bash\n   grep \"Access denied\" ~/.vikingbot/logs/vikingbot.log\n   ```\n3. **Check for unexpected file modifications**\n4. **Rotate all credentials**\n5. **Update to latest version**\n6. **Report the incident** to maintainers\n\n## Security Features\n\n### Built-in Security Controls\n\n✅ **Input Validation**\n- Path traversal protection on file operations\n- Dangerous command pattern detection\n- Input length limits on HTTP requests\n\n✅ **Authentication**\n- Allow-list based access control\n- Failed authentication attempt logging\n- Open by default (configure allowFrom for production use)\n\n✅ **Resource Protection**\n- Command execution timeouts (60s default)\n- Output truncation (10KB limit)\n- HTTP request timeouts (10-30s)\n\n✅ **Secure Communication**\n- HTTPS for all external API calls\n- TLS for Telegram API\n- WhatsApp bridge: localhost-only binding + optional token auth\n\n## Known Limitations\n\n⚠️ **Current Security Limitations:**\n\n1. **No Rate Limiting** - Users can send unlimited messages (add your own if needed)\n2. **Plain Text Config** - API keys stored in plain text (use keyring for production)\n3. **No Session Management** - No automatic session expiry\n4. **Limited Command Filtering** - Only blocks obvious dangerous patterns\n5. **No Audit Trail** - Limited security event logging (enhance as needed)\n\n## Security Checklist\n\nBefore deploying vikingbot:\n\n- [ ] API keys stored securely (not in code)\n- [ ] Config file permissions set to 0600\n- [ ] `allowFrom` lists configured for all channels\n- [ ] Running as non-root user\n- [ ] File system permissions properly restricted\n- [ ] Dependencies updated to latest secure versions\n- [ ] Logs monitored for security events\n- [ ] Rate limits configured on API providers\n- [ ] Backup and disaster recovery plan in place\n- [ ] Security review of custom skills/tools\n\n## Updates\n\n**Last Updated**: 2026-02-03\n\nFor the latest security updates and announcements, check:\n- GitHub Security Advisories: https://github.com/HKUDS/vikingbot/security/advisories\n- Release Notes: https://github.com/HKUDS/vikingbot/releases\n\n## License\n\nSee LICENSE file for details.\n"

[内置插件清单](#5-内置插件清单)\n6. [关于动态修改 SKILL.md 的分析](#6-关于动态修改-skillmd-的分析)\n\n---\n\n## 1. 插件机制概述\n\nOpenClaw 采用**分层、可扩展的插件架构**，支持三种类型的插件：\n\n- **内置插件 (Bundled)** - 随 OpenClaw 一起发布\n- **托管插件 (Managed)** - 通过 ClawHub 安装管理\n- **工作空间插件 (Workspace)** - 项目特定的本地插件\n\n插件发现层级遵循以下优先级（从高到低）：\n\n```\nConfig paths → Workspace → Global → Bundled\n```\n\n---\n\n## 2. 插件分类体系\n\nOpenClaw 支持以下扩展类型：\n\n| 扩展类型 | 说明 | 示例 |\n|---------|------|------|\n| **Channel 插件** | 消息通道集成 | Matrix, Zalo, WhatsApp |\n| **Tool 插件** | 工具扩展 | 文件操作、网络请求 |\n| **Gateway RPC** | RPC 接口扩展 | 自定义 API 端点 |\n| **HTTP Handlers** | HTTP 请求处理器 | Webhook 处理 |\n| **CLI Commands** | 命令行命令 | 自定义 CLI 指令 |\n| **Services** | 后台服务 | 定时任务、监听器 |\n| **Hooks** | 事件钩子 | 生命周期钩子 |\n| **Provider Auth** | 认证提供者 | OAuth、API Key 管理 |\n\n---\n\n## 3. 注册与加载机制\n\n### 3.1 插件加载器\n\nOpenClaw 使用 **jiti** 作为插件加载器，支持**运行时直接执行 TypeScript**，无需预编译：\n\n```typescript\n// 核心加载函数来自 pi-coding-agent 包\nimport { loadSkillsFromDir } from '@mariozechner/pi-coding-agent';\n\n// 加载技能目录\nconst skills = await loadSkillsFromDir(skillDir);\n```\n\n### 3.2 注册 API\n\n插件通过以下 API 注册到系统：\n\n```typescript\n// 注册通道\napi.registerChannel(config: ChannelConfig);\n\n// 注册工具\napi.registerTool(name: string, handler: ToolHandler);\n\n// 注册 Gateway 方法\napi.registerGatewayMethod(method: string, handler: Function);\n```\n\n### 3.3 文件监听与热重载\n\nOpenClaw 使用 `chokidar` 监听文件变化，实现热重载：\n\n```typescript\n// 来自 src/agents/skills/refresh.ts\nconst watcher = chokidar.watch(watchTargets, {\n  ignoreInitial: true,\n  awaitWriteFinish: {\n    stabilityThreshold: debounceMs,\n    pollInterval: 100,\n  },\n  ignored: DEFAULT_SKILLS_WATCH_IGNORED,\n});\n```\n\n---\n\n## 4. 架构设计详解\n\n### 4.1 基于 Hook 的事件驱动架构\n\nOpenClaw 的核心是事件驱动的 Hook 系统，主要事件包括：\n\n| 事件 | 触发时机 |\n|------|---------|\n| `message:inbound` | 消息流入系统 |\n| `message:outbound` | 消息流出系统 |\n| `agent:start` | Agent 开始工作 |\n| `agent:complete` | Agent 完成工作 |\n| `config:reload` | 配置重新加载 |\n| `before_prompt_build` | 构建 prompt 之前 |\n| `llm_input` | LLM 输入前 |\n| `llm_output` | LLM 输出后 |\n\n### 4.2 插件 SDK 能力\n\n插件 SDK 提供以下核心能力：\n\n```typescript\ninterface PluginSDK {\n  // 后台服务\n  Background: {\n    start(service: BackgroundService): void;\n    stop(serviceId: string): void;\n  };\n\n  // 生命周期钩子\n  Lifecycle: {\n    on(event: LifecycleEvent, handler: Function): void;\n  };\n\n  // 配置管理\n  Config: {\n    get<T>(key: string): T;\n    set<T>(key: string, value: T): void;\n  };\n\n  // 日志\n  Logger: {\n    info(msg: string): void;\n    error(msg: string): void;\n    debug(msg: string): void;\n  };\n}\n```\n\n---\n\n## 5. 内置插件清单\n\n### 5.1 内置通道 (Bundled Channels)\n\n| 通道 | 说明 |\n|------|------|\n| WhatsApp | WhatsApp 商业 API |\n| Telegram | Telegram Bot |\n| Slack | Slack App |\n| Discord | Discord Bot |\n| Signal | Signal 集成 |\n| iMessage | Apple iMessage |\n| Google Chat | Google Workspace Chat |\n\n### 5.2 扩展插件 (位于 `/extensions/`)\n\n| 插件 | 说明 |\n|------|------|\n| Matrix | 去中心化聊天协议 |\n| Microsoft Teams | 微软团队协作 |\n| Zalo (User/Business) | 越南社交应用 |\n| Nostr | 去中心化社交网络 |\n| LINE | 日本即时通讯 |\n| Mattermost | 开源团队协作 |\n| Nextcloud Talk | 私有云通话 |\n\n---\n\n## 6. 关于动态修改 SKILL.md 的分析\n\n### 6.1 核心结论\n\n**OpenClaw 目前无法直接在 skill 加载时修改 SKILL.md 内容。**\n\n原因：\n1. **无生命周期钩子** - Skill 系统没有提供 `onLoad`、`beforeLoad` 等钩子\n2. **静态声明式架构** - Skills 通过 `SKILL.md` 静态定义，使用 `pi-coding-agent` 包加载，没有预留修改入口\n3. **只读解析** - Frontmatter 解析器只读取不写入\n4. **加载后只读** - Skill 加载后被用于构建 system prompt，本身不会被修改\n\n### 6.2 可行替代方案\n\n#### 方案 1: 外部预处理脚本（推荐）\n\n在启动 OpenClaw 之前，运行脚本修改 SKILL.md：\n\n```bash\n#!/bin/bash\n# preprocess-skills.sh\nnode scripts/modify-skills.js\nopenclaw start  # 启动 OpenClaw\n```\n\n```javascript\n// scripts/modify-skills.js\nconst fs = require('fs');\nconst path = require('path');\nconst yaml = require('yaml');\n\nconst skillPath = process.env.SKILL_PATH || './skills/my-skill/SKILL.md';\nconst content = fs.readFileSync(skillPath, 'utf8');\n\n// 解析 frontmatter\nconst match = content.match(/^---\\n([\\s\\S]*?)\\n---\\n([\\s\\S]*)$/);\nif (match) {\n  const frontmatter = yaml.parse(match[1]);\n  const body = match[2];\n\n  // 动态修改内容\n  frontmatter.lastModified = new Date().toISOString();\n  frontmatter.dynamicValue = calculateDynamicValue();\n\n  // 写回文件\n  const newContent = `---\\n${yaml.stringify(frontmatter)}---\\n${body}`;\n  fs.writeFileSync(skillPath, newContent);\n}\n```\n\n#### 方案 2: 使用 OpenClaw Hooks 系统\n\n利用 `before_prompt_build` hook 在构建 prompt 时动态修改 skill 内容：\n\n```typescript\n// 在你的插件中\nimport { definePlugin } from 'openclaw';\n\nexport default definePlugin({\n  name: 'dynamic-skill-modifier',\n\n  hooks: {\n    // 在构建 prompt 之前修改 skill 内容\n    before_prompt_build: async ({ skills, context }) => {\n      // 动态修改 skill 对象（不修改文件，只修改内存中的表示）\n      for (const skill of skills) {\n        if (skill.name === 'my-dynamic-skill') {\n          skill.content = modifySkillContent(skill.content, context);\n        }\n      }\n      return { skills };\n    }\n  }\n});\n```\n\n#### 方案 3: 自定义 Skill 加载器（高级）\n\n创建一个自定义的 skill 加载插件，拦截加载过程：\n\n```typescript\n// plugins/dynamic-skill-loader.ts\nimport { loadSkillsFromDir } from 'pi-coding-agent';\nimport * as fs from 'fs';\nimport * as path from 'path';\n\nexport class DynamicSkillLoader {\n  async loadSkills(skillDir: string) {\n    // 1. 复制 skill 到临时目录\n    const tempDir = this.createTempCopy(skillDir);\n\n    // 2. 修改临时目录中的 SKILL.md\n    this.modifySkillMdFiles(tempDir);\n\n    // 3. 从临时目录加载\n    return loadSkillsFromDir(tempDir);\n  }\n\n  private modifySkillMdFiles(dir: string) {\n    const skillMdFiles = this.findSkillMdFiles(dir);\n    for (const file of skillMdFiles) {\n      let content = fs.readFileSync(file, 'utf8');\n\n      // 动态修改内容\n      content = this.applyDynamicModifications(content);\n\n      fs.writeFileSync(file, content);\n    }\n  }\n\n  private applyDynamicModifications(content: string): string {\n    // 添加动态生成的内容\n    const dynamicSection = `\\n\\n<!-- 动态生成于 ${new Date().toISOString()} -->\\n`;\n    return content + dynamicSection;\n  }\n}\n```\n\n#### 方案 4: 文件监听 + 触发重载（最符合 OpenClaw 设计）\n\n利用 OpenClaw 已有的文件监听机制，在修改 SKILL.md 后自动重载：\n\n```typescript\n// 在你的构建脚本中\nimport * as chokidar from 'chokidar';\nimport * as fs from 'fs';\n\n// 监听原始 skill 定义文件\nconst watcher = chokidar.watch('./skill-sources/**/*.md');\n\nwatcher.on('change', (filepath) => {\n  console.log(`Source changed: ${filepath}`);\n\n  // 重新生成 SKILL.md\n  generateSkillMd(filepath);\n});\n\nfunction generateSkillMd(sourcePath: string) {\n  const source = fs.readFileSync(sourcePath, 'utf8');\n\n  // 动态生成 frontmatter\n  const frontmatter = {\n    name: extractName(source),\n    version: calculateVersion(),\n    lastBuild: new Date().toISOString(),\n    dynamicConfig: loadDynamicConfig()\n  };\n\n  // 写入 SKILL.md（触发 OpenClaw 重载）\n  const skillMd = `---\\n${yaml.stringify(frontmatter)}---\\n${extractBody(source)}`;\n  fs.writeFileSync('./skills/my-skill/SKILL.md', skillMd);\n}\n```\n\n### 6.3 方案对比\n\n| 方案 | 复杂度 | 侵入性 | 适用场景 | 推荐度 |\n|------|--------|--------|----------|--------|\n| 预处理脚本 | 低 | 低 | 启动前一次性修改 | ★★★★★ |\n| Hooks 系统 | 中 | 中 | 运行时动态修改内存中的 skill | ★★★★ |\n| 自定义加载器 | 高 | 高 | 需要完全控制加载过程 | ★★★ |\n| 文件监听重载 | 中 | 低 | 需要持续同步外部变更 | ★★★★ |\n\n### 6.4 核心结论\n\n**OpenClaw 的 Skill 系统是静态声明式的**，设计理念是：\n- Skill 定义（SKILL.md）是**只读的声明**\n- 动态行为通过 **Hooks** 和 **插件** 实现\n- 文件变化通过 **监听 + 重载** 机制处理\n\n因此，如果需要\"在 skill 加载时修改 SKILL.md\"，应该：\n1. **在加载前** 通过预处理脚本修改（方案 1）\n2. **在加载后** 通过 Hooks 修改内存中的表示（方案 2）\n3. **避免** 尝试在加载过程中 hack 内部机制\n\n这种设计与 OpenClaw 的整体架构哲学一致：**声明式配置 + 程序化扩展**。\n"

API Endpoints / API 端点\n\n### 4.1 Bot API (via OpenViking Server)\n\n| Method | Path | Description |\n|--------|------|-------------|\n| GET | `/api/v1/bot/health` | Health check |\n| POST | `/api/v1/bot/chat` | Send message (non-streaming) |\n| POST | `/api/v1/bot/chat/stream` | Send message (streaming, SSE) |\n\n### 4.2 Response Codes\n\n| Code | Condition |\n|------|-----------|\n| 200 | Success |\n| 503 | `--with-bot` not enabled or bot service unavailable |\n| 502 | Bot service returned an error |\n\n---\n\n## 5. Usage Examples / 使用示例\n\n### 5.1 Start the services / 启动服务\n\n```bash\n# 启动 OpenViking Server (带 --with-bot 会自动启动 vikingbot gateway)\nopenviking-server --with-bot\n\n# Output:\n# OpenViking HTTP Server is running on 127.0.0.1:1933\n# Bot API proxy enabled, forwarding to http://localhost:18791\n# [vikingbot] Starting gateway on port 18791...\n```\n\n**说明 / Note:**\n- `--with-bot`: 自动在同一机器上启动 `vikingbot gateway` 进程\n- 不加 `--with-bot`: 仅启动 OpenViking Server，不会启动 Vikingbot\n\n**设计意图 / Design Rationale:**\nOpenViking Server 统一代理 Vikingbot 的 CLI 请求，目的是：\n1. **共享鉴权机制** - 复用 OpenViking Server 的统一认证中间件\n2. **端口共享** - 服务端部署时可共享端口，简化网络配置\n\n### 5.2 Using `ov chat` CLI / 使用 `ov chat` CLI\n\n```bash\n# Interactive mode (default)\nov chat\n\n# Single message mode\nov chat -m \"Hello, bot!\"\n\n# Use custom endpoint\nVIKINGBOT_ENDPOINT=http://localhost:1933/api/v1/bot ov chat -m \"Hello!\"\n```\n\n### 5.3 Direct HTTP API usage / 直接 HTTP API 使用\n\n```bash\n# Health check\ncurl http://localhost:1933/api/v1/bot/health\n\n# Send a message\ncurl -X POST http://localhost:1933/api/v1/bot/chat \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\n    \"message\": \"Hello!\",\n    \"session_id\": \"test-session\",\n    \"user_id\": \"test-user\"\n  }'\n\n# Streaming response\ncurl -X POST http://localhost:1933/api/v1/bot/chat/stream \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\n    \"message\": \"Hello!\",\n    \"session_id\": \"test-session\",\n    \"stream\": true\n  }'\n```\n\n---\n\n## 6. Configuration / 配置\n\n### 6.1 配置共享说明 / Configuration Sharing\n\n**重要 / Important:** Vikingbot 与 OpenViking Server 共享同一个 `ov.conf` 配置文件，不再使用 `~/.vikingbot/config.json`。\n\nVikingbot 的配置项统一放在 `ov.conf` 的 `bot` 字段下：\n\n```json\n{\n  \"server\": {\n    \"host\": \"127.0.0.1\",\n    \"port\": 1933,\n    \"root_api_key\": \"your-api-key\",\n    \"with_bot\": true,\n    \"bot_api_url\": \"http://localhost:18791\"\n  },\n  \"bot\": {\n    \"agents\": {\n      \"model\": \"openai/gpt-4o\",\n      \"max_tool_iterations\": 50,\n      \"memory_window\": 50\n    },\n    \"gateway\": {\n      \"host\": \"0.0.0.0\",\n      \"port\": 18791\n    },\n    \"channels\": [\n      {\"type\": \"feishu\", \"enabled\": false, \"app_id\": \"\", \"app_secret\": \"\"}\n    ],\n    \"sandbox\": {\n      \"backend\": \"direct\",\n      \"mode\": \"shared\"\n    }\n  }\n}\n```\n\n**配置说明 / Configuration Notes:**\n- `server.with_bot`: 启用时自动在同一机器上启动 Vikingbot gateway\n- `bot.agents`: Agent 配置，包括 LLM 模型、最大工具迭代次数、记忆窗口\n- `bot.gateway`: HTTP Gateway 监听地址\n- `bot.channels`: 渠道配置列表，支持 openapi、feishu 等\n- `bot.sandbox`: 沙箱执行配置\n\n### 6.2 Command-line Options\n\n```bash\n# Enable Bot API proxy\nopenviking-server --with-bot\n\n# Custom bot URL\nopenviking-server --with-bot --bot-url http://localhost:8080\n\n# With config file\nopenviking-server --config /path/to/ov.conf\n```\n\n---\n\n*End of Document*\n"

Git Clone 加速\n\n将 GitHub 仓库链接前加上 `https://githubproxy.cc/` 前缀：\n\n```bash\n# 原始链接\ngit clone https://github.com/username/repo.git\n\n# 加速链接\ngit clone https://githubproxy.cc/https://github.com/username/repo.git\n```\n\n### 2. 文件下载加速\n\n支持以下类型的 GitHub 资源加速：\n\n- **Raw 文件**: `https://raw.githubusercontent.com/...`\n- **Release 文件**: 项目发布的附件\n- **Archive 压缩包**: 仓库打包下载\n- **Gist 文件**: `gist.github.com` 或 `gist.githubusercontent.com`\n\n```bash\n# 原始链接\nwget https://raw.githubusercontent.com/username/repo/main/file.txt\n\n# 加速链接\nwget https://githubproxy.cc/https://raw.githubusercontent.com/username/repo/main/file.txt\n```\n\n### 3. 使用辅助脚本\n\n使用 `scripts/convert_url.py` 自动转换 GitHub 链接：\n\n```bash\npython scripts/convert_url.py \"https://github.com/username/repo.git\"\n```\n\n## 链接转换规则\n\n| 原始链接格式 | 转换后格式 |\n|-------------|-----------|\n| `https://github.com/username/repo.git` | `https://githubproxy.cc/https://github.com/username/repo.git` |\n| `https://raw.githubusercontent.com/...` | `https://githubproxy.cc/https://raw.githubusercontent.com/...` |\n| `https://github.com/.../releases/download/...` | `https://githubproxy.cc/https://github.com/.../releases/download/...` |\n| `https://github.com/.../archive/...` | `https://githubproxy.cc/https://github.com/.../archive/...` |\n\n## 注意事项\n\n- 本服务仅供学习研究使用，请勿滥用\n- 如果 githubproxy.cc 不可用，请尝试备用服务 ghfast.top\n- 不支持 SSH Key 方式的 git clone\n- Push、PR、Issue 等操作建议直接使用官方 GitHub 地址\n"

    "content": "---\nname: skill-creator\ndescription: Create or update AgentSkills. Use when designing, structuring, or packaging skills with scripts, references, and assets.\n---\n\n# Skill Creator\n\nThis skill provides guidance for creating effective skills.\n\n## About Skills\n\nSkills are modular, self-contained packages that extend the agent's capabilities by providing\nspecialized knowledge, workflows, and tools. Think of them as \"onboarding guides\" for specific\ndomains or tasks—they transform the agent from a general-purpose agent into a specialized agent\nequipped with procedural knowledge that no model can fully possess.\n\n### What Skills Provide\n\n1. Specialized workflows - Multi-step procedures for specific domains\n2. Tool integrations - Instructions for working with specific file formats or APIs\n3. Domain expertise - Company-specific knowledge, schemas, business logic\n4. Bundled resources - Scripts, references, and assets for complex and repetitive tasks\n\n## Core Principles\n\n### Concise is Key\n\nThe context window is a public good. Skills share the context window with everything else the agent needs: system prompt, conversation history, other Skills' metadata, and the actual user request.\n\n**Default assumption: the agent is already very smart.** Only add context the agent doesn't already have. Challenge each piece of information: \"Does the agent really need this explanation?\" and \"Does this paragraph justify its token cost?\"\n\nPrefer concise examples over verbose explanations.\n\n### Set Appropriate Degrees of Freedom\n\nMatch the level of specificity to the task's fragility and variability:\n\n**High freedom (text-based instructions)**: Use when multiple approaches are valid, decisions depend on context, or heuristics guide the approach.\n\n**Medium freedom (pseudocode or scripts with parameters)**: Use when a preferred pattern exists, some variation is acceptable, or configuration affects behavior.\n\n**Low freedom (specific scripts, few parameters)**: Use when operations are fragile and error-prone, consistency is critical, or a specific sequence must be followed.\n\nThink of the agent as exploring a path: a narrow bridge with cliffs needs specific guardrails (low freedom), while an open field allows many routes (high freedom).\n\n### Anatomy of a Skill\n\nEvery skill consists of a required SKILL.md file and optional bundled resources:\n\n```\nskill-name/\n├── SKILL.md (required)\n│   ├── YAML frontmatter metadata (required)\n│   │   ├── name: (required)\n│   │   └── description: (required)\n│   └── Markdown instructions (required)\n└── Bundled Resources (optional)\n    ├── scripts/          - Executable code (Python/Bash/etc.)\n    ├── references/       - Documentation intended to be loaded into context as needed\n    └── assets/           - Files used in output (templates, icons, fonts, etc.)\n```\n\n#### SKILL.md (required)\n\nEvery SKILL.md consists of:\n\n- **Frontmatter** (YAML): Contains `name` and `description` fields. These are the only fields that the agent reads to determine when the skill gets used, thus it is very important to be clear and comprehensive in describing what the skill is, and when it should be used.\n- **Body** (Markdown): Instructions and guidance for using the skill. Only loaded AFTER the skill triggers (if at all).\n\n#### Bundled Resources (optional)\n\n##### Scripts (`scripts/`)\n\nExecutable code (Python/Bash/etc.) for tasks that require deterministic reliability or are repeatedly rewritten.\n\n- **When to include**: When the same code is being rewritten repeatedly or deterministic reliability is needed\n- **Example**: `scripts/rotate_pdf.py` for PDF rotation tasks\n- **Benefits**: Token efficient, deterministic, may be executed without loading into context\n- **Note**: Scripts may still need to be read by the agent for patching or environment-specific adjustments\n\n##### References (`references/`)\n\nDocumentation and reference material intended to be loaded as needed into context to inform the agent's process and thinking.\n\n- **When to include**: For documentation that the agent should reference while working\n- **Examples**: `references/finance.md` for financial schemas, `references/mnda.md` for company NDA template, `references/policies.md` for company policies, `references/api_docs.md` for API specifications\n- **Use cases**: Database schemas, API documentation, domain knowledge, company policies, detailed workflow guides\n- **Benefits**: Keeps SKILL.md lean, loaded only when the agent determines it's needed\n- **Best practice**: If files are large (>10k words), include grep search patterns in SKILL.md\n- **Avoid duplication**: Information should live in either SKILL.md or references files, not both. Prefer references files for detailed information unless it's truly core to the skill—this keeps SKILL.md lean while making information discoverable without hogging the context window. Keep only essential procedural instructions and workflow guidance in SKILL.md; move detailed reference material, schemas, and examples to references files.\n\n##### Assets (`assets/`)\n\nFiles not intended to be loaded into context, but rather used within the output the agent produces.\n\n- **When to include**: When the skill needs files that will be used in the final output\n- **Examples**: `assets/logo.png` for brand assets, `assets/slides.pptx` for PowerPoint templates, `assets/frontend-template/` for HTML/React boilerplate, `assets/font.ttf` for typography\n- **Use cases**: Templates, images, icons, boilerplate code, fonts, sample documents that get copied or modified\n- **Benefits**: Separates output resources from documentation, enables the agent to use files without loading them into context\n\n#### What to Not Include in a Skill\n\nA skill should only contain essential files that directly support its functionality. Do NOT create extraneous documentation or auxiliary files, including:\n\n- README.md\n- INSTALLATION_GUIDE.md\n- QUICK_REFERENCE.md\n- CHANGELOG.md\n- etc.\n\nThe skill should only contain the information needed for an AI agent to do the job at hand. It should not contain auxiliary context about the process that went into creating it, setup and testing procedures, user-facing documentation, etc. Creating additional documentation files just adds clutter and confusion.\n\n### Progressive Disclosure Design Principle\n\nSkills use a three-level loading system to manage context efficiently:\n\n1. **Metadata (name + description)** - Always in context (~100 words)\n2. **SKILL.md body** - When skill triggers (<5k words)\n3. **Bundled resources** - As needed by the agent (Unlimited because scripts can be executed without reading into context window)\n\n#### Progressive Disclosure Patterns\n\nKeep SKILL.md body to the essentials and under 500 lines to minimize context bloat. Split content into separate files when approaching this limit. When splitting out content into other files, it is very important to reference them from SKILL.md and describe clearly when to read them, to ensure the reader of the skill knows they exist and when to use them.\n\n**Key principle:** When a skill supports multiple variations, frameworks, or options, keep only the core workflow and selection guidance in SKILL.md. Move variant-specific details (patterns, examples, configuration) into separate reference files.\n\n**Pattern 1: High-level guide with references**\n\n```markdown\n# PDF Processing\n\n## Quick start\n\nExtract text with pdfplumber:\n[code example]\n\n## Advanced features\n\n- **Form filling**: See [FORMS.md](FORMS.md) for complete guide\n- **API reference**: See [REFERENCE.md](REFERENCE.md) for all methods\n- **Examples**: See [EXAMPLES.md](EXAMPLES.md) for common patterns\n```\n\nthe agent loads FORMS.md, REFERENCE.md, or EXAMPLES.md only when needed.\n\n**Pattern 2: Domain-specific organization**\n\nFor Skills with multiple domains, organize content by domain to avoid loading irrelevant context:\n\n```\nbigquery-skill/\n├── SKILL.md (overview and navigation)\n└── reference/\n    ├── finance.md (revenue, billing metrics)\n    ├── sales.md (opportunities, pipeline)\n    ├── product.md (API usage, features)\n    └── marketing.md (campaigns, attribution)\n```\n\nWhen a user asks about sales metrics, the agent only reads sales.md.\n\nSimilarly, for skills supporting multiple frameworks or variants, organize by variant:\n\n```\ncloud-deploy/\n├── SKILL.md (workflow + provider selection)\n└── references/\n    ├── aws.md (AWS deployment patterns)\n    ├── gcp.md (GCP deployment patterns)\n    └── azure.md (Azure deployment patterns)\n```\n\nWhen the user chooses AWS, the agent only reads aws.md.\n\n**Pattern 3: Conditional details**\n\nShow basic content, link to advanced content:\n\n```markdown\n# DOCX Processing\n\n## Creating documents\n\nUse docx-js for new documents. See [DOCX-JS.md](DOCX-JS.md).\n\n## Editing documents\n\nFor simple edits, modify the XML directly.\n\n**For tracked changes**: See [REDLINING.md](REDLINING.md)\n**For OOXML details**: See [OOXML.md](OOXML.md)\n```\n\nthe agent reads REDLINING.md or OOXML.md only when the user needs those features.\n\n**Important guidelines:**\n\n- **Avoid deeply nested references** - Keep references one level deep from SKILL.md. All reference files should link directly from SKILL.md.\n- **Structure longer reference files** - For files longer than 100 lines, include a table of contents at the top so the agent can see the full scope when previewing.\n\n## Skill Creation Process\n\nSkill creation involves these steps:\n\n1. Understand the skill with concrete examples\n2. Plan reusable skill contents (scripts, references, assets)\n3. Initialize the skill (run init_skill.py)\n4. Edit the skill (implement resources and write SKILL.md)\n5. Package the skill (run package_skill.py)\n6. Iterate based on real usage\n\nFollow these steps in order, skipping only if there is a clear reason why they are not applicable.\n\n### Skill Naming\n\n- Use lowercase letters, digits, and hyphens only; normalize user-provided titles to hyphen-case (e.g., \"Plan Mode\" -> `plan-mode`).\n- When generating names, generate a name under 64 characters (letters, digits, hyphens).\n- Prefer short, verb-led phrases that describe the action.\n- Namespace by tool when it improves clarity or triggering (e.g., `gh-address-comments`, `linear-address-issue`).\n- Name the skill folder exactly after the skill name.\n\n### Step 1: Understanding the Skill with Concrete Examples\n\nSkip this step only when the skill's usage patterns are already clearly understood. It remains valuable even when working with an existing skill.\n\nTo create an effective skill, clearly understand concrete examples of how the skill will be used. This understanding can come from either direct user examples or generated examples that are validated with user feedback.\n\nFor example, when building an image-editor skill, relevant questions include:\n\n- \"What functionality should the image-editor skill support? Editing, rotating, anything else?\"\n- \"Can you give some examples of how this skill would be used?\"\n- \"I can imagine users asking for things like 'Remove the red-eye from this image' or 'Rotate this image'. Are there other ways you imagine this skill being used?\"\n- \"What would a user say that should trigger this skill?\"\n\nTo avoid overwhelming users, avoid asking too many questions in a single message. Start with the most important questions and follow up as needed for better effectiveness.\n\nConclude this step when there is a clear sense of the functionality the skill should support.\n\n### Step 2: Planning the Reusable Skill Contents\n\nTo turn concrete examples into an effective skill, analyze each example by:\n\n1. Considering how to execute on the example from scratch\n2. Identifying what scripts, references, and assets would be helpful when executing these workflows repeatedly\n\nExample: When building a `pdf-editor` skill to handle queries like \"Help me rotate this PDF,\" the analysis shows:\n\n1. Rotating a PDF requires re-writing the same code each time\n2. A `scripts/rotate_pdf.py` script would be helpful to store in the skill\n\nExample: When designing a `frontend-webapp-builder` skill for queries like \"Build me a todo app\" or \"Build me a dashboard to track my steps,\" the analysis shows:\n\n1. Writing a frontend webapp requires the same boilerplate HTML/React each time\n2. An `assets/hello-world/` template containing the boilerplate HTML/React project files would be helpful to store in the skill\n\nExample: When building a `big-query` skill to handle queries like \"How many users have logged in today?\" the analysis shows:\n\n1. Querying BigQuery requires re-discovering the table schemas and relationships each time\n2. A `references/schema.md` file documenting the table schemas would be helpful to store in the skill\n\nTo establish the skill's contents, analyze each concrete example to create a list of the reusable resources to include: scripts, references, and assets.\n\n### Step 3: Initializing the Skill\n\nAt this point, it is time to actually create the skill.\n\nSkip this step only if the skill being developed already exists, and iteration or packaging is needed. In this case, continue to the next step.\n\nWhen creating a new skill from scratch, always run the `init_skill.py` script. The script conveniently generates a new template skill directory that automatically includes everything a skill requires, making the skill creation process much more efficient and reliable.\n\nUsage:\n\n```bash\nscripts/init_skill.py <skill-name> --path <output-directory> [--resources scripts,references,assets] [--examples]\n```\n\nExamples:\n\n```bash\nscripts/init_skill.py my-skill --path skills/public\nscripts/init_skill.py my-skill --path skills/public --resources scripts,references\nscripts/init_skill.py my-skill --path skills/public --resources scripts --examples\n```\n\nThe script:\n\n- Creates the skill directory at the specified path\n- Generates a SKILL.md template with proper frontmatter and TODO placeholders\n- Optionally creates resource directories based on `--resources`\n- Optionally adds example files when `--examples` is set\n\nAfter initialization, customize the SKILL.md and add resources as needed. If you used `--examples`, replace or delete placeholder files.\n\n### Step 4: Edit the Skill\n\nWhen editing the (newly-generated or existing) skill, remember that the skill is being created for another instance of the agent to use. Include information that would be beneficial and non-obvious to the agent. Consider what procedural knowledge, domain-specific details, or reusable assets would help another the agent instance execute these tasks more effectively.\n\n#### Learn Proven Design Patterns\n\nConsult these helpful guides based on your skill's needs:\n\n- **Multi-step processes**: See references/workflows.md for sequential workflows and conditional logic\n- **Specific output formats or quality standards**: See references/output-patterns.md for template and example patterns\n\nThese files contain established best practices for effective skill design.\n\n#### Start with Reusable Skill Contents\n\nTo begin implementation, start with the reusable resources identified above: `scripts/`, `references/`, and `assets/` files. Note that this step may require user input. For example, when implementing a `brand-guidelines` skill, the user may need to provide brand assets or templates to store in `assets/`, or documentation to store in `references/`.\n\nAdded scripts must be tested by actually running them to ensure there are no bugs and that the output matches what is expected. If there are many similar scripts, only a representative sample needs to be tested to ensure confidence that they all work while balancing time to completion.\n\nIf you used `--examples`, delete any placeholder files that are not needed for the skill. Only create resource directories that are actually required.\n\n#### Update SKILL.md\n\n**Writing Guidelines:** Always use imperative/infinitive form.\n\n##### Frontmatter\n\nWrite the YAML frontmatter with `name` and `description`:\n\n- `name`: The skill name\n- `description`: This is the primary triggering mechanism for your skill, and helps the agent understand when to use the skill.\n  - Include both what the Skill does and specific triggers/contexts for when to use it.\n  - Include all \"when to use\" information here - Not in the body. The body is only loaded after triggering, so \"When to Use This Skill\" sections in the body are not helpful to the agent.\n  - Example description for a `docx` skill: \"Comprehensive document creation, editing, and analysis with support for tracked changes, comments, formatting preservation, and text extraction. Use when the agent needs to work with professional documents (.docx files) for: (1) Creating new documents, (2) Modifying or editing content, (3) Working with tracked changes, (4) Adding comments, or any other document tasks\"\n\nDo not include any other fields in YAML frontmatter.\n\n##### Body\n\nWrite instructions for using the skill and its bundled resources.\n\n### Step 5: Packaging a Skill\n\nOnce development of the skill is complete, it must be packaged into a distributable .skill file that gets shared with the user. The packaging process automatically validates the skill first to ensure it meets all requirements:\n\n```bash\nscripts/package_skill.py <path/to/skill-folder>\n```\n\nOptional output directory specification:\n\n```bash\nscripts/package_skill.py <path/to/skill-folder> ./dist\n```\n\nThe packaging script will:\n\n1. **Validate** the skill automatically, checking:\n\n   - YAML frontmatter format and required fields\n   - Skill naming conventions and directory structure\n   - Description completeness and quality\n   - File organization and resource references\n\n2. **Package** the skill if validation passes, creating a .skill file named after the skill (e.g., `my-skill.skill`) that includes all files and maintains the proper directory structure for distribution. The .skill file is a zip file with a .skill extension.\n\nIf validation fails, the script will report the errors and exit without creating a package. Fix any validation errors and run the packaging command again.\n\n### Step 6: Iterate\n\nAfter testing the skill, users may request improvements. Often this happens right after using the skill, with fresh context of how the skill performed.\n\n**Iteration workflow:**\n\n1. Use the skill on real tasks\n2. Notice struggles or inefficiencies\n3. Identify how SKILL.md or bundled resources should be updated\n4. Implement changes and test again\n"

Prefer exec background mode for long-running, non-interactive tasks.\n\n## Quickstart (isolated socket, exec tool)\n\n```bash\nSOCKET_DIR=\"${NANOBOT_TMUX_SOCKET_DIR:-${TMPDIR:-/tmp}/vikingbot-tmux-sockets}\"\nmkdir -p \"$SOCKET_DIR\"\nSOCKET=\"$SOCKET_DIR/vikingbot.sock\"\nSESSION=vikingbot-python\n\ntmux -S \"$SOCKET\" new -d -s \"$SESSION\" -n shell\ntmux -S \"$SOCKET\" send-keys -t \"$SESSION\":0.0 -- 'PYTHON_BASIC_REPL=1 python3 -q' Enter\ntmux -S \"$SOCKET\" capture-pane -p -J -t \"$SESSION\":0.0 -S -200\n```\n\nAfter starting a session, always print monitor commands:\n\n```\nTo monitor:\n  tmux -S \"$SOCKET\" attach -t \"$SESSION\"\n  tmux -S \"$SOCKET\" capture-pane -p -J -t \"$SESSION\":0.0 -S -200\n```\n\n## Socket convention\n\n- Use `NANOBOT_TMUX_SOCKET_DIR` environment variable.\n- Default socket path: `\"$NANOBOT_TMUX_SOCKET_DIR/vikingbot.sock\"`.\n\n## Targeting panes and naming\n\n- Target format: `session:window.pane` (defaults to `:0.0`).\n- Keep names short; avoid spaces.\n- Inspect: `tmux -S \"$SOCKET\" list-sessions`, `tmux -S \"$SOCKET\" list-panes -a`.\n\n## Finding sessions\n\n- List sessions on your socket: `{baseDir}/scripts/find-sessions.sh -S \"$SOCKET\"`.\n- Scan all sockets: `{baseDir}/scripts/find-sessions.sh --all` (uses `NANOBOT_TMUX_SOCKET_DIR`).\n\n## Sending input safely\n\n- Prefer literal sends: `tmux -S \"$SOCKET\" send-keys -t target -l -- \"$cmd\"`.\n- Control keys: `tmux -S \"$SOCKET\" send-keys -t target C-c`.\n\n## Watching output\n\n- Capture recent history: `tmux -S \"$SOCKET\" capture-pane -p -J -t target -S -200`.\n- Wait for prompts: `{baseDir}/scripts/wait-for-text.sh -t session:0.0 -p 'pattern'`.\n- Attaching is OK; detach with `Ctrl+b d`.\n\n## Spawning processes\n\n- For python REPLs, set `PYTHON_BASIC_REPL=1` (non-basic REPL breaks send-keys flows).\n\n## Windows / WSL\n\n- tmux is supported on macOS/Linux. On Windows, use WSL and install tmux inside WSL.\n- This skill is gated to `darwin`/`linux` and requires `tmux` on PATH.\n\n## Orchestrating Coding Agents (Codex, Claude Code)\n\ntmux excels at running multiple coding agents in parallel:\n\n```bash\nSOCKET=\"${TMPDIR:-/tmp}/codex-army.sock\"\n\n# Create multiple sessions\nfor i in 1 2 3 4 5; do\n  tmux -S \"$SOCKET\" new-session -d -s \"agent-$i\"\ndone\n\n# Launch agents in different workdirs\ntmux -S \"$SOCKET\" send-keys -t agent-1 \"cd /tmp/project1 && codex --yolo 'Fix bug X'\" Enter\ntmux -S \"$SOCKET\" send-keys -t agent-2 \"cd /tmp/project2 && codex --yolo 'Fix bug Y'\" Enter\n\n# Poll for completion (check if prompt returned)\nfor sess in agent-1 agent-2; do\n  if tmux -S \"$SOCKET\" capture-pane -p -t \"$sess\" -S -3 | grep -q \"❯\"; then\n    echo \"$sess: DONE\"\n  else\n    echo \"$sess: Running...\"\n  fi\ndone\n\n# Get full output from completed session\ntmux -S \"$SOCKET\" capture-pane -p -t agent-1 -S -500\n```\n\n**Tips:**\n- Use separate git worktrees for parallel fixes (no branch conflicts)\n- `pnpm install` first before running codex in fresh clones\n- Check for shell prompt (`❯` or `$`) to detect completion\n- Codex needs `--yolo` or `--full-auto` for non-interactive fixes\n\n## Cleanup\n\n- Kill a session: `tmux -S \"$SOCKET\" kill-session -t \"$SESSION\"`.\n- Kill all sessions on a socket: `tmux -S \"$SOCKET\" list-sessions -F '#{session_name}' | xargs -r -n1 tmux -S \"$SOCKET\" kill-session -t`.\n- Remove everything on the private socket: `tmux -S \"$SOCKET\" kill-server`.\n\n## Helper: wait-for-text.sh\n\n`{baseDir}/scripts/wait-for-text.sh` polls a pane for a regex (or fixed string) with a timeout.\n\n```bash\n{baseDir}/scripts/wait-for-text.sh -t session:0.0 -p 'pattern' [-F] [-T 20] [-i 0.5] [-l 2000]\n```\n\n- `-t`/`--target` pane target (required)\n- `-p`/`--pattern` regex to match (required); add `-F` for fixed string\n- `-T` timeout seconds (integer, default 15)\n- `-i` poll interval seconds (default 0.5)\n- `-l` history lines to search (integer, default 1000)\n"

    "content": "# OpenViking Helm Chart\n\nDeploy OpenViking on Kubernetes using Helm.\n\n## Prerequisites\n\n- Kubernetes 1.24+\n- Helm 3.x\n- A storage class that supports `ReadWriteOnce` persistent volumes (for RocksDB data)\n\n## Installation\n\n### Quick Start\n\n```bash\nhelm install openviking ./deploy/helm/openviking \\\n  --set config.server.root_api_key=\"YOUR_ROOT_API_KEY\" \\\n  --set config.embedding.dense.api_key=\"YOUR_VOLCENGINE_API_KEY\" \\\n  --set config.vlm.api_key=\"YOUR_VOLCENGINE_API_KEY\"\n```\n\n### Install with Custom Values\n\nCreate a `my-values.yaml` file:\n\n```yaml\nreplicaCount: 1\n\nresources:\n  limits:\n    cpu: \"4\"\n    memory: 8Gi\n  requests:\n    cpu: \"1\"\n    memory: 2Gi\n\npersistence:\n  size: 50Gi\n  storageClass: \"gp3\"\n\nconfig:\n  storage:\n    workspace: /app/data/openviking_workspace\n  log:\n    level: INFO\n    output: stdout\n  server:\n    host: \"0.0.0.0\"\n    port: 1933\n    workers: 1\n    root_api_key: \"your-secret-key\"\n  embedding:\n    dense:\n      api_base: \"https://ark.cn-beijing.volces.com/api/v3\"\n      api_key: \"your-volcengine-api-key\"\n      provider: \"volcengine\"\n      dimension: 1024\n      model: \"doubao-embedding-vision-250615\"\n      input: \"multimodal\"\n    max_concurrent: 10\n  vlm:\n    api_base: \"https://ark.cn-beijing.volces.com/api/v3\"\n    api_key: \"your-volcengine-api-key\"\n    provider: \"volcengine\"\n    model: \"doubao-seed-2-0-pro-260215\"\n    temperature: 0.0\n    max_retries: 2\n    thinking: false\n    max_concurrent: 100\n```\n\nThen install:\n\n```bash\nhelm install openviking ./deploy/helm/openviking -f my-values.yaml\n```\n\n### Using Secrets for API Keys\n\nFor production, avoid putting API keys directly in values. Use `extraEnv` with\nKubernetes secrets instead:\n\n```bash\n# Create a secret\nkubectl create secret generic openviking-api-keys \\\n  --from-literal=embedding-api-key=\"YOUR_KEY\" \\\n  --from-literal=vlm-api-key=\"YOUR_KEY\"\n```\n\nThen reference it in your values:\n\n```yaml\nextraEnv:\n  - name: EMBEDDING_API_KEY\n    valueFrom:\n      secretKeyRef:\n        name: openviking-api-keys\n        key: embedding-api-key\n  - name: VLM_API_KEY\n    valueFrom:\n      secretKeyRef:\n        name: openviking-api-keys\n        key: vlm-api-key\n```\n\n## Configuration\n\n| Parameter | Description | Default |\n|-----------|-------------|---------|\n| `replicaCount` | Number of replicas | `1` |\n| `image.repository` | Container image repository | `ghcr.io/volcengine/openviking` |\n| `image.tag` | Container image tag | Chart appVersion |\n| `image.pullPolicy` | Image pull policy | `IfNotPresent` |\n| `service.type` | Kubernetes service type | `ClusterIP` |\n| `service.port` | Service port | `1933` |\n| `persistence.enabled` | Enable persistent storage | `true` |\n| `persistence.size` | PVC size | `20Gi` |\n| `persistence.storageClass` | Storage class name | `\"\"` (default) |\n| `persistence.existingClaim` | Use an existing PVC | `\"\"` |\n| `resources.limits.cpu` | CPU limit | `2` |\n| `resources.limits.memory` | Memory limit | `4Gi` |\n| `resources.requests.cpu` | CPU request | `500m` |\n| `resources.requests.memory` | Memory request | `1Gi` |\n| `ingress.enabled` | Enable ingress | `false` |\n| `config.server.root_api_key` | API key required when server binds to 0.0.0.0 | `\"\"` |\n| `config` | Full ov.conf configuration object | See `values.yaml` |\n| `extraEnv` | Additional environment variables | `[]` |\n\n## Upgrading\n\n```bash\nhelm upgrade openviking ./deploy/helm/openviking -f my-values.yaml\n```\n\nThe deployment uses a `Recreate` strategy to avoid data corruption from\nmultiple pods accessing the same RocksDB volume simultaneously.\n\n## Uninstalling\n\n```bash\nhelm uninstall openviking\n```\n\nNote: The PersistentVolumeClaim is not deleted automatically. To remove stored\ndata:\n\n```bash\nkubectl delete pvc openviking-data\n```\n"

    "content": "# OpenViking 多租户设计方案\n\n## Context\n\nOpenViking 已定义了 `UserIdentifier(account_id, user_id, agent_id)` 三元组（PR #120），但多租户隔离尚未实施。当前状态：\n\n- **认证**：单一全局 `api_key`，HMAC 比较（`openviking/server/auth.py`）\n- **无 RBAC**：所有认证用户拥有完全访问权限\n- **无存储隔离**：`VikingFS._uri_to_path` 将 `viking://` 映射到 `/local/`，无 account_id 前缀\n- **VectorDB**：单一 `context` collection，无租户过滤\n- **服务层**：`OpenVikingService` 持有单例 `_user`，不支持请求级用户上下文\n\n目标：实现完整的多租户支持，包括 API Key 管理、RBAC、存储隔离。不考虑向后兼容。\n\n---\n\n## 一、整体架构\n\n```\nRequest\n  │\n  ▼\n[Auth Middleware] ── 提取 API Key，先比对 root key，再查 user key 表 → (account_id, user_id, role)\n  │\n  ▼\n[RBAC Guard] ── 按角色检查操作权限\n  │\n  ▼\n[RequestContext] ── UserIdentifier + Role 注入为 FastAPI 依赖\n  │\n  ▼\n[Router] ── 传递 RequestContext 到 Service\n  │\n  ▼\n[Service Layer] ── 请求级用户上下文（非单例）\n  │\n  ├─► [VikingFS] ── 单例，接受 RequestContext 参数，_uri_to_path 按 account_id 隔离，逐层权限过滤\n  └─► [VectorDB] ── 单 collection，查询注入 account_id + owner_space 过滤\n```\n\n核心原则：\n- **身份从 API Key 解析**，贯穿全链路\n- **account 级隔离**：AGFS 路径前缀 + VectorDB account_id 过滤\n- **user/agent 级隔离**：目录遍历时逐层过滤，只展示当前用户有权限的目录和文件\n- VikingFS 通过 RequestContext 获取租户和用户信息\n\n---\n\n## 二、API Key 管理\n\n### 2.1 两层 Key 结构\n\n| 类型 | 格式 | 解析结果 | 存储位置 |\n|------|------|----------|----------|\n| Root Key | `secrets.token_hex(32)` | role=ROOT | `ov.conf` server 段 |\n| User Key | `secrets.token_hex(32)` | (account_id, user_id, role) | per-account `/{account_id}/_system/users.json` |\n\n所有 API Key 均为纯随机 token，不带前缀，不携带任何身份信息。Key 本身不区分 root 还是 user —— 服务端通过查表确定身份：先比对 root key，不匹配则查 user key 索引。\n\n用户的角色（ADMIN / USER）不由 key 决定，而是存储在 account 内的用户注册表中。\n\n### 2.2 User Key 机制\n\n注册用户时生成随机 key，存入对应 account 的 `users.json`。验证时查表匹配。\n\n**生成**：`secrets.token_hex(32)` → `7f3a9c1e...`（存入 users.json）\n**验证**：先比对 root key → 不匹配 → 在内存索引中查找 → 得到 `(account_id, user_id, role)`\n\n**完整场景**：\n\n```\n1. Root 创建工作区 acme，指定 alice 为首个 admin\n   POST /api/v1/admin/accounts  {\"account_id\": \"acme\", \"admin_user_id\": \"alice\"}\n   → 创建工作区 + 注册 alice(role=admin) + 返回 alice 的 key: 7f3a9c1e...\n\n2. alice 用 key 访问 API\n   GET /api/v1/fs/ls?uri=viking://  -H \"X-API-Key: 7f3a9c1e...\"   → 200 OK\n\n3. alice（admin）注册普通用户 bob\n   POST /api/v1/admin/accounts/acme/users  {\"user_id\": \"bob\"}      → 注册成功 + 返回 key: d91f5b2a...\n\n4. bob 丢了 key，alice 重新生成（旧 key 立即失效）\n   POST /api/v1/admin/accounts/acme/users/bob/key                  → e82d4e0f...（新 key）\n   bob 用旧的 d91f5b2a... 访问 → 401（已失效）\n\n5. bob 的 key 泄露 → 重新生成即可，只影响 bob\n\n6. alice 移除 bob\n   DELETE /api/v1/admin/accounts/acme/users/bob                    → 注册表和 key 一起删除\n   bob 再用 key 访问 → 查表找不到 → 401\n```\n\n### 2.3 Key 存储\n\n- **Root Key**：`ov.conf` 的 `server` 段（静态配置）\n- **全局工作区列表**：AGFS `/_system/accounts.json`\n- **Per-account 用户注册表**：AGFS `/{account_id}/_system/users.json`\n\n存储结构示例：\n\n```json\n// /_system/accounts.json —— 全局工作区列表\n{\n    \"accounts\": {\n        \"default\": { \"created_at\": \"2026-02-13T00:00:00Z\" },\n        \"acme\": { \"created_at\": \"2026-02-13T10:00:00Z\" }\n    }\n}\n\n// /acme/_system/users.json —— acme 工作区的用户注册表\n{\n    \"users\": {\n        \"alice\": { \"role\": \"admin\", \"key\": \"7f3a9c1e...\" },\n        \"bob\":   { \"role\": \"user\",  \"key\": \"d91f5b2a...\" }\n    }\n}\n```\n\n启动时加载所有 account 的 `users.json` 到内存，构建全局 key → (account_id, user_id, role) 索引。写操作持久化到对应 account 目录。\n\n**为什么存 AGFS**：User key 是运行时通过 Admin API 动态增删的，不能放 ov.conf。选择 AGFS 的核心理由是多节点一致性——多个 server 共享同一个 AGFS 后端时，一个节点创建的用户其他节点立即可见。\n\n### 2.4 新模块 `openviking/server/api_keys.py`\n\n```python\nclass APIKeyManager:\n    \"\"\"API Key 生命周期管理与解析\"\"\"\n\n    def __init__(self, root_key: str, agfs_client: AGFSClient)\n    async def load()                                     # 加载所有 account 的 users.json 到内存\n    async def save_account(account_id: str)              # 持久化指定 account 的 users.json\n    def resolve(api_key: str) -> ResolvedIdentity        # Key → 身份 + 角色\n    def create_account(account_id: str, admin_user_id: str) -> str  # 创建工作区 + 首个 admin，返回 admin 的 user key\n    def delete_account(account_id: str)                  # 删除工作区\n    def register_user(account_id, user_id, role) -> str  # 注册用户，返回 user key\n    def remove_user(account_id, user_id)                 # 移除用户\n    def regenerate_key(account_id, user_id) -> str       # 重新生成 user key（旧 key 失效）\n    def set_role(account_id, user_id, role)              # 修改用户角色（仅 ROOT）\n```\n\n---\n\n## 三、认证流程\n\n### 3.1 核心类型\n\n新建 `openviking/server/identity.py`：\n\n```python\nclass Role(str, Enum):\n    ROOT = \"root\"\n    ADMIN = \"admin\"          # account 内的管理员（用户属性，非 key 类型）\n    USER = \"user\"\n\n@dataclass\nclass ResolvedIdentity:\n    role: Role\n    account_id: Optional[str] = None\n    user_id: Optional[str] = None\n    agent_id: Optional[str] = None  # 来自 X-OpenViking-Agent header\n\n@dataclass\nclass RequestContext:\n    user: UserIdentifier       # account_id + user_id + agent_id\n    role: Role\n```\n\n### 3.2 认证流程\n\n1. 从 `X-API-Key` 或 `Authorization: Bearer` 提取 Key\n2. 若未配置 `root_api_key`，进入 **dev 模式**：返回 `(role=ROOT, account_id=\"default\", user_id=\"default\")`\n3. 顺序匹配（Key 无前缀，纯随机 token）：\n   - HMAC 比对 root key → 匹配则 role=ROOT\n   - 查 user key 内存索引 → 匹配则得到 (account_id, user_id, role)，role 为 ADMIN 或 USER\n   - 均不匹配 → 401 Unauthorized\n4. 从 `X-OpenViking-Agent` header 读取 `agent_id`（默认 `\"default\"`）\n5. 构造 `RequestContext(UserIdentifier(account_id, user_id, agent_id), role)`\n\n### 3.3 FastAPI 依赖注入\n\n改动 `openviking/server/auth.py`：\n\n```python\nasync def resolve_identity(request, x_api_key, authorization, x_openviking_agent) -> ResolvedIdentity\ndef require_role(*roles) -> Depends  # 角色守卫工厂\ndef get_request_context(identity) -> RequestContext  # 构造 RequestContext\n```\n\n所有 Router 从 `Depends(verify_api_key)` 迁移到 `Depends(get_request_context)`。\n\n---\n\n## 四、RBAC 模型\n\n### 4.1 三层角色\n\n采用 ROOT / ADMIN / USER 三层角色。ADMIN 是用户在 account 内的角色属性，不由 key 类型决定。两层 key（root/user）+ 角色属性的设计：\n\n1. **委托式管理链路**：ROOT 创建 account 并指定首个 admin → admin 自行注册用户并下发 user key。ROOT 不需要介入日常用户管理。\n2. **灵活的 admin 管理**：一个 account 可以有多个 admin，ROOT 可以随时提升/降低用户角色。\n3. **权限最小化**：user key 泄露只影响单个用户数据；admin 泄露影响该 account 但不波及其他 account；root key 影响全局。\n4. **数据访问边界**：ADMIN 可访问本 account 下所有用户数据（管理审计需要），USER 只能访问自己的隔离空间。\n\n### 4.2 角色与权限\n\n| 角色 | 身份 | 能力 |\n|------|------|------|\n| ROOT | 系统管理员 | 一切：创建/删除工作区、指定 admin、跨租户访问 |\n| ADMIN | 工作区管理员 | 管理本 account 用户、下发 User Key、账户内全量数据访问 |\n| USER | 普通用户 | 访问自己的 user/agent/session scope + account 内共享 resources |\n\n权限矩阵：\n\n| 操作 | ROOT | ADMIN | USER |\n|------|------|-------|------|\n| 创建/删除工作区 | Y | N | N |\n| 提升用户为 admin | Y | N | N |\n| 注册/移除用户 | Y | Y (本 account) | N |\n| 下发/重置 User Key | Y | Y (本 account) | N |\n| FS 读写 (own scope) | Y | Y | Y |\n| 跨 account 访问 | Y | N | N |\n| VectorDB 搜索 | Y (全局) | Y (本 account) | Y (本 account) |\n| Session 管理 | Y | Y (本 account 所有) | Y (仅自己的) |\n| 系统状态 | Y | Y | N |\n\n### 4.3 Agent 归属\n\nAgent 目录由 `user_id + agent_id` 共同决定，每个用户与 agent 的组合有独立数据空间：\n\n```\n/{account_id}/agent/{md5(user_id + agent_id)[:12]}/memories/cases/\n/{account_id}/agent/{md5(user_id + agent_id)[:12]}/skills/\n/{account_id}/agent/{md5(user_id + agent_id)[:12]}/instructions/\n```\n\nalice 和 bob 使用同一 agent_id 时，各自有独立的记忆和技能空间，互不可见。如果后续需要团队共享 agent 知识，可通过 ACL 机制（见 5.7）扩展。\n\n### 4.4 Admin API\n\n新增 Router: `openviking/server/routers/admin.py`\n\n```\nPOST   /api/v1/admin/accounts                              创建工作区 + 首个 admin (ROOT)\nGET    /api/v1/admin/accounts                              列出工作区 (ROOT)\nDELETE /api/v1/admin/accounts/{account_id}                 删除工作区 (ROOT)，级联清理数据\nPOST   /api/v1/admin/accounts/{account_id}/users           注册用户 (ROOT, ADMIN)\nDELETE /api/v1/admin/accounts/{account_id}/users/{uid}     移除用户 (ROOT, ADMIN)\nGET    /api/v1/admin/accounts/{account_id}/users/{uid}/key 重新生成 User Key (ROOT, ADMIN)\nPUT    /api/v1/admin/accounts/{account_id}/users/{uid}/role 修改用户角色 (ROOT)\n```\n\n---\n\n## 五、存储隔离\n\n### 5.1 三维隔离模型\n\n存储隔离有三个独立维度：account、user、agent。\n\n- **account**：顶层隔离，不同租户之间完全不可见\n- **user**：同一 account 内，不同用户的私有数据互不可见。用户记忆、资源、session 属于用户本人\n- **agent**：同一 account 内，agent 目录由 user_id + agent_id 共同决定，每用户独立（见 4.3）\n\n**Space 标识符**：`UserIdentifier` 提供两个方法 `user_space_name()` 和 `agent_space_name()`：\n\n```python\ndef user_space_name(self) -> str:\n    \"\"\"用户级 space，不含 agent_id\"\"\"\n    return f\"{self._account_id}_{hashlib.md5(self._user_id.encode()).hexdigest()[:8]}\"\n\ndef agent_space_name(self) -> str:\n    \"\"\"Agent 级 space，由 user_id + agent_id 共同决定\"\"\"\n    return hashlib.md5((self._user_id + self._agent_id).encode()).hexdigest()[:12]\n```\n\n### 5.2 各 Scope 的隔离方式\n\n| scope | AGFS 路径 | 隔离维度 | 说明 |\n|-------|-----------|----------|------|\n| `user/memories` | `/{account_id}/user/{user_space}/memories/` | account + user | 用户偏好、实体、事件属于用户本人 |\n| `agent/memories` | `/{account_id}/agent/{agent_space}/memories/` | account + user + agent | agent 的学习记忆，每用户独立 |\n| `agent/skills` | `/{account_id}/agent/{agent_space}/skills/` | account + user + agent | agent 的能力集，每用户独立 |\n| `agent/instructions` | `/{account_id}/agent/{agent_space}/instructions/` | account + user + agent | agent 的行为规则，每用户独立 |\n| `resources/` | `/{account_id}/resources/` | account | account 内共享的知识资源 |\n| `session/` | `/{account_id}/session/{user_space}/{session_id}/` | account + user | 用户的对话记录 |\n| `redo/` | `/{account_id}/_system/redo/` | account | 崩溃恢复 redo 标记 |\n| `_system/`（全局） | `/_system/` | 系统级 | 全局工作区列表 |\n| `_system/`（per-account） | `/{account_id}/_system/` | account | 用户注册表 |\n\n### 5.3 AGFS 文件系统隔离\n\n**改动文件**: `openviking/storage/viking_fs.py`\n\nVikingFS 保持单例，不持有任何租户状态。多租户通过参数传递实现：\n\n**调用链路**：\n1. 公开方法（`ls`、`read`、`write` 等）接收 `ctx: RequestContext` 参数\n2. 公开方法从 `ctx.account_id` 提取 account_id，传给内部方法\n3. 内部方法（`_uri_to_path`、`_path_to_uri`、`_collect_uris` 等）接收 `account_id: str` 参数，不依赖 ctx\n\n**URI → AGFS 路径转换**（加 account_id 前缀）：\n\n```\nviking://user/{user_space}/memories/x + account_id=\"acme\"\n→ /local/acme/user/{user_space}/memories/x\n```\n\n**AGFS 路径 → URI 转换**（去 account_id 前缀）：\n\n```\n/local/acme/user/{user_space}/memories/x + account_id=\"acme\"\n→ viking://user/{user_space}/memories/x\n```\n\n返回给调用方的 URI 不含 account_id，对用户透明。account_id 只存在于 AGFS 物理路径层。\n\n```python\n# 公开方法：接收 ctx，提取 account_id，结果按权限过滤\nasync def ls(self, uri: str, ctx: RequestContext) -> List[str]:\n    path = self._uri_to_path(uri, account_id=ctx.account_id)\n    entries = await self._agfs.ls(path)\n    uris = [self._path_to_uri(e, account_id=ctx.account_id) for e in entries]\n    return [u for u in uris if self._is_accessible(u, ctx)]  # 权限过滤，见 5.4\n\n# 内部方法：只接收 account_id，不依赖 ctx\ndef _uri_to_path(self, uri: str, account_id: str = \"\") -> str:\n    remainder = uri[len(\"viking://\"):].strip(\"/\")\n    if account_id:\n        return f\"/local/{account_id}/{remainder}\" if remainder else f\"/local/{account_id}\"\n    return f\"/local/{remainder}\" if remainder else \"/local\"\n\ndef _path_to_uri(self, path: str, account_id: str = \"\") -> str:\n    inner = path[len(\"/local/\"):]                    # \"acme/user/{space}/memories/x\"\n    if account_id and inner.startswith(account_id + \"/\"):\n        inner = inner[len(account_id) + 1:]          # \"user/{space}/memories/x\"\n    return f\"viking://{inner}\"\n```\n\n### 5.4 逐层权限过滤（Phase2）\n\nuser/agent 级隔离通过**逐层遍历时过滤**实现。用户可以从公共根目录（如 `viking://resources`）开始遍历，但每一层只能看到自己有权限的条目。\n\n**示例**：\n\n```\n# alice（USER 角色）\nls viking://resources           → 看到 account 内共享的 resources（无 user 隔离）\nls viking://agent/memories      → 只看到 alice 当前 agent 的 {agent_space}/\nls viking://user/memories       → 只看到 {alice_user_space}/\n\n# admin（ADMIN 角色）\nls viking://resources           → 同上，resources 在 account 内共享\nls viking://user/memories       → 看到所有用户的 space 目录\n```\n\n**实现**：VikingFS 新增 `_is_accessible()` 方法：\n\n```python\ndef _is_accessible(self, uri: str, ctx: RequestContext) -> bool:\n    \"\"\"判断当前用户是否能访问该 URI\"\"\"\n    if ctx.role in (Role.ROOT, Role.ADMIN):\n        return True\n\n    # 结构性目录（不含 space，如 viking://user/memories）→ 允许遍历\n    space_in_uri = self._extract_space_from_uri(uri)\n    if space_in_uri is None:\n        return True\n\n    # 含 space 的 URI → 检查 space 是否属于当前用户或其 agent\n    return space_in_uri in (\n        ctx.user.user_space_name(),\n        ctx.user.agent_space_name(),\n    )\n```\n\n- **列举操作**（`ls`、`tree`、`glob`）：AGFS 返回全量结果后，用 `_is_accessible` 过滤\n- **读写操作**（`read`、`write`、`mkdir` 等）：执行前调 `_is_accessible` 校验，无权限则拒绝\n- **将来加 ACL**：`_is_accessible` 内部扩展为查 ACL 表，接口不变（见 5.7）\n\n### 5.5 VectorDB 租户隔离\n\n**改动文件**: `openviking/storage/collection_schemas.py`\n\n单 `context` collection，schema 新增两个字段：\n\n- `account_id`（string）：account 级过滤\n- `owner_space`（string）：user/agent 级过滤，值为记录所有者的 `user_space_name()` 或 `agent_space_name()`\n\n查询过滤策略（由 retriever 根据 ctx 构造）：\n\n| 角色 | 过滤条件 |\n|------|---------|\n| ROOT | 无 |\n| ADMIN | `account_id` = ctx.account_id |\n| USER | `account_id` = ctx.account_id AND `owner_space` IN (ctx.user.user_space_name(), ctx.user.agent_space_name()) |\n\n写入时，`Context` 对象携带 `account_id` 和 `owner_space`，通过 `EmbeddingMsgConverter` 透传到 VectorDB。`owner_space` 始终只存原始所有者，不因共享而修改。\n\n### 5.6 目录初始化\n\n**改动文件**: `openviking/core/directories.py`\n\n- 创建新账户时，初始化 account 级预设目录结构（公共根：`viking://user`、`viking://agent`、`viking://resources` 等）\n- 用户首次访问时，懒初始化 user space 子目录（`viking://user/{user_space}/memories/preferences` 等）\n- agent 首次使用时，懒初始化 agent space 子目录（`viking://agent/{agent_space}/memories/cases` 等）\n\n### 5.7 未来 ACL 扩展方向（本版不实现）\n\n当需要支持用户间资源共享（如 alice 共享某个 resources 目录给 bob）时，有两种扩展路径：\n\n**方案 a：独立 ACL 表**\n\n共享关系存储在独立的 ACL 表中（AGFS 或 VectorDB），不修改数据记录本身：\n\n```\n# ACL 记录\n{ \"grantee_space\": \"bob_user_space\", \"granted_uri_prefix\": \"viking://resources/{alice_space}/project-x\" }\n\n# bob 查询时\n1. 解析可访问 space 列表：own spaces + 查 ACL 表得到被授权的 spaces\n2. VectorDB filter: owner_space IN [bob_user_space, bob_agent_space, alice_user_space]\n3. VikingFS _is_accessible: 检查 own space OR ACL 授权\n```\n\n优势：数据记录不变，授权/撤销即时生效，不需要批量更新记录。\n\n**方案 b：VectorDB 新增 `shared_spaces` 字段**\n\n在被共享的**目录记录**（非叶子节点）上新增 `shared_spaces` 列表字段，标记哪些 space 有访问权限：\n\n```\n# 目录记录\n{ \"uri\": \"viking://resources/{alice_space}/project-x\", \"owner_space\": \"alice_space\", \"shared_spaces\": [\"bob_space\"] }\n\n# bob 遍历时\n_is_accessible 检查: owner_space 匹配 OR space in shared_spaces\n```\n\n优势：权限信息自包含在目录节点上，遍历时不需要额外查 ACL 表。需要配合遍历时的权限继承（子节点继承父目录的 shared_spaces）。\n\n两种方案可结合使用。具体选型在 ACL 设计时确定。\n\n---\n\n## 六、配置变更\n\n### `ov.conf` server 段\n\n```json\n{\n  \"server\": {\n    \"host\": \"0.0.0.0\",\n    \"port\": 1933,\n    \"root_api_key\": \"your-secret-root-key\",\n    \"cors_origins\": [\"*\"]\n  }\n}\n```\n\n**改动文件**: `openviking/server/config.py`\n\n```python\n@dataclass\nclass ServerConfig:\n    host: str = \"0.0.0.0\"\n    port: int = 1933\n    root_api_key: Optional[str] = None   # 替代原 api_key\n    cors_origins: List[str] = field(default_factory=lambda: [\"*\"])\n```\n\n- `root_api_key`：替代原有的 `api_key`，用于 ROOT 身份认证。为 None 时进入本地开发模式（跳过认证）。\n- 已移除 `private_key`（User Key 采用随机存储方案，不需要加密密钥）和 `multi_tenant`（统一多租户，不区分部署模式）。\n\n---\n\n## 七、客户端变更\n\n核心变化：多租户前客户端需要自行传递 `account_id` 和 `user_id`，多租户后这两个字段由服务端从 API Key 解析，客户端只需提供 `api_key` 和可选的 `agent_id`。\n\n| 项目 | 多租户前 | 多租户后 |\n|------|---------|---------|\n| 身份来源 | 客户端构造 UserIdentifier | 服务端从 API Key 解析 |\n| 必须参数 | url, api_key, account_id, user_id | url, api_key |\n| 可选参数 | agent_id | agent_id |\n| 身份 header | `X-OpenViking-User` + `X-OpenViking-Agent` | 仅 `X-OpenViking-Agent` |\n\n### 7.1 Python SDK\n\n**改动文件**: `openviking_cli/client/http.py`, `openviking_cli/client/sync_http.py`\n\n```python\n# 多租户后：身份由服务端从 api_key 解析\nclient = ov.SyncHTTPClient(\n    url=\"http://localhost:1933\",\n    api_key=\"7f3a9c1e...\",             # 服务端查表解析出 account_id + user_id\n    agent_id=\"coding-agent\",           # 可选，默认 \"default\"\n)\n```\n\n### 7.2 CLI\n\n**改动文件**: `openviking_cli/session/user_id.py`\n\n`ovcli.conf` 新增 `agent_id` 字段：\n\n```json\n{\n  \"url\": \"http://localhost:1933\",\n  \"api_key\": \"7f3a9c1e...\",\n  \"agent_id\": \"coding-agent\",\n  \"output\": \"table\"\n}\n```\n\nCLI 发起请求时通过 `X-OpenViking-Agent` header 携带 agent_id。不再需要配置 `account_id` 和 `user_id`。\n\n### 7.3 嵌入模式\n\n嵌入模式支持多租户，通过构造参数传入 `UserIdentifier`。无 API Key 认证，身份由调用方直接声明（嵌入模式的调用方是可信代码）。\n\n```python\n# 默认（单用户，使用 default 工作区）\nclient = ov.Client(path=\"/data/openviking\")\n\n# 多租户（指定身份）\nfrom openviking_cli.session.user_id import UserIdentifier\nuser = UserIdentifier(\"acme\", \"alice\", \"coding-agent\")\nclient = ov.Client(path=\"/data/openviking\", user=user)\n```\n\n内部将 `UserIdentifier` 转为 `RequestContext` 传给 Service 层，路径隔离和权限过滤逻辑与 HTTP 模式一致。\n\n---\n\n## 八、部署模式\n\n多租户为**破坏性改造**，不保留单租户模式。所有部署统一走多租户路径结构。\n\n### 8.1 统一路径结构\n\n所有 account（包括 default）使用层级路径：\n\n```\n/local/{account_id}/resources/...\n/local/{account_id}/user/{user_space}/memories/...\n/local/{account_id}/agent/{agent_space}/memories/...\n```\n\n原有扁平路径 `/local/resources/...` 不再使用，现有数据需重新导入。\n\n### 8.2 运行模式\n\n| 配置 | 行为 |\n|------|------|\n| 不配置 `root_api_key` | Dev 模式：跳过认证，使用 default account + default user + ROOT 角色 |\n| 配置 `root_api_key` | 生产模式：强制 API Key 认证，支持多 account 和多用户 |\n\n两种配置使用**完全相同的路径结构和 VectorDB schema**，区别仅在认证层：\n- Dev 模式不验证 Key，自动填充默认身份\n- 生产模式从 Key 解析身份\n\n代码无分支逻辑，VikingFS 和 VectorDB 只有一套实现。\n\n### 8.3 升级与数据迁移\n\n旧版（单租户）升级到多租户后，存储结构变化：\n\n| 影响 | 旧结构 | 新结构 |\n|------|--------|--------|\n| resources | `/local/resources/...` | `/local/default/resources/...` |\n| user memories | `/local/user/memories/...` | `/local/default/user/{default_space}/memories/...` |\n| agent data | `/local/agent/memories/...` | `/local/default/agent/{default_space}/memories/...` |\n| session | `/local/session/...` | `/local/default/session/{default_space}/...` |\n| VectorDB | 无 `account_id` 字段 | 需补 `account_id=\"default\"` + `owner_space` |\n\n迁移目标始终是 `default` account + `default` user，映射关系完全确定。\n\n提供 CLI 迁移命令（Phase 2 实现）：\n\n```bash\npython -m openviking migrate\n```\n\n迁移逻辑：\n1. 检测旧结构（`/local/resources/` 存在但 `/local/default/` 不存在）\n2. 创建 default account 目录结构\n3. 搬迁 AGFS 文件到新路径\n4. Batch update VectorDB 记录，补充 `account_id` 和 `owner_space` 字段\n5. 输出迁移报告（搬迁文件数、更新记录数）\n\n用户升级流程：停服 → 备份 → 执行 `migrate` → 验证 → 启动新版\n\n---\n\n## 九、实施分期与任务拆解\n\n### Phase 1：API 层多租户能力定义\n\n实施顺序：`T1 → T3 → T2 → T4 → T5 → T10/T11 并行 → T12 → T16-P1 → T17-P1 → T14-P1`\n\n---\n\n#### T1: 身份与角色类型定义\n\n**新建** `openviking/server/identity.py`，依赖：无\n\n定义三个类型，供后续所有任务引用：\n\n```python\nfrom enum import Enum\nfrom dataclasses import dataclass\nfrom typing import Optional\nfrom openviking.session.user_id import UserIdentifier\n\nclass Role(str, Enum):\n    ROOT = \"root\"\n    ADMIN = \"admin\"          # account 内的管理员（用户属性，非 key 类型）\n    USER = \"user\"\n\n@dataclass\nclass ResolvedIdentity:\n    \"\"\"认证中间件的输出：从 API Key 解析出的原始身份信息\"\"\"\n    role: Role\n    account_id: Optional[str] = None   # ROOT 可能无 account_id\n    user_id: Optional[str] = None      # ROOT 可能无 user_id\n    agent_id: Optional[str] = None     # 来自 X-OpenViking-Agent header\n\n@dataclass\nclass RequestContext:\n    \"\"\"请求级上下文，贯穿 Router → Service → VikingFS 全链路\"\"\"\n    user: UserIdentifier    # 完整三元组（account_id, user_id, agent_id）\n    role: Role\n\n    @property\n    def account_id(self) -> str:\n        return self.user.account_id\n```\n\n**注意**：`RequestContext` 而非 `ResolvedIdentity` 是下游使用的类型。`ResolvedIdentity` 只在 auth 层内部使用，转换为 `RequestContext` 后传递。原因：`ResolvedIdentity` 的字段都是 Optional（ROOT 没有 account_id），而 `RequestContext.user` 是确定的 `UserIdentifier`——对于 ROOT，填入 `account_id=\"default\"`。\n\n---\n\n#### T3: ServerConfig 更新\n\n**修改** `openviking/server/config.py`，依赖：无\n\n改动点：\n\n```python\n# 改前\n@dataclass\nclass ServerConfig:\n    host: str = \"0.0.0.0\"\n    port: int = 1933\n    api_key: Optional[str] = None                          # ← 删除\n    cors_origins: List[str] = field(default_factory=lambda: [\"*\"])\n\n# 改后\n@dataclass\nclass ServerConfig:\n    host: str = \"0.0.0.0\"\n    port: int = 1933\n    root_api_key: Optional[str] = None                     # ← 替代 api_key\n    cors_origins: List[str] = field(default_factory=lambda: [\"*\"])\n```\n\n`load_server_config()` 中对应修改读取字段：\n```python\nconfig = ServerConfig(\n    host=server_data.get(\"host\", \"0.0.0.0\"),\n    port=server_data.get(\"port\", 1933),\n    root_api_key=server_data.get(\"root_api_key\"),          # ← 改\n    cors_origins=server_data.get(\"cors_origins\", [\"*\"]),\n)\n```\n\n---\n\n#### T2: API Key Manager\n\n**新建** `openviking/server/api_keys.py`，依赖：T1\n\n##### 存储结构\n\nPer-account 存储，两级文件：\n\n```python\n# /_system/accounts.json — 全局工作区列表\n{\n    \"accounts\": {\n        \"default\": {\"created_at\": \"2026-02-12T10:00:00Z\"},\n        \"acme\": {\"created_at\": \"2026-02-13T08:00:00Z\"}\n    }\n}\n\n# /{account_id}/_system/users.json — 该 account 的用户注册表\n{\n    \"users\": {\n        \"alice\": {\"role\": \"admin\", \"key\": \"7f3a9c1e...\"},\n        \"bob\": {\"role\": \"user\", \"key\": \"d91f5b2a...\"}\n    }\n}\n```\n\n内存索引（启动时从所有 account 加载）：\n```python\nself._user_keys: Dict[str, UserKeyEntry] = {}   # {key_str -> (account_id, user_id, role)}\nself._accounts: Dict[str, AccountInfo] = {}      # {account_id -> AccountInfo(users)}\n```\n\n##### 方法逻辑\n\n**`__init__(root_key, agfs_url)`**：\n- 存储 root_key\n- 创建 pyagfs.AGFSClient(agfs_url) 用于读写 AGFS 文件\n\n**`async load()`**：\n- 从 AGFS 读取 `/_system/accounts.json`，若不存在则创建 default account\n- 遍历每个 account，读取 `/{account_id}/_system/users.json`\n- 构建全局 key → (account_id, user_id, role) 索引\n\n**`async save_account(account_id)`**：\n- 将指定 account 的用户数据写回 `/{account_id}/_system/users.json`\n- 同时更新 `/_system/accounts.json`（若 account 列表有变化）\n\n**`resolve(api_key) -> ResolvedIdentity`**：\n```\n# Key 无前缀，顺序匹配\nif hmac.compare_digest(key, self._root_key):\n    → ResolvedIdentity(role=ROOT)\nentry = self._user_keys.get(key)\nif entry:\n    → ResolvedIdentity(role=entry.role, account_id=entry.account_id, user_id=entry.user_id)\nraise UnauthenticatedError\n```\n\n**`create_account(account_id, admin_user_id) -> str`**：\n- 验证 account_id 格式\n- 检查 account_id 不重复\n- 创建 account 记录到 `_accounts`\n- 注册首个 admin 用户，生成 `secrets.token_hex(32)` 作为 key\n- 持久化 `/_system/accounts.json` 和 `/{account_id}/_system/users.json`\n- 返回 admin 的 user key\n\n**`delete_account(account_id)`**：\n- 从 `_accounts` 删除\n- 从 `_user_keys` 中删除该 account 的所有 key\n- 删除 `/_system/accounts.json` 中的记录\n- **注意**：AGFS 数据和 VectorDB 数据的级联清理由 Admin Router 调用方负责\n\n**`register_user(account_id, user_id, role=\"user\") -> str`**：\n- 检查 account_id 存在\n- 生成 `secrets.token_hex(32)` 作为 key\n- 写入 account 用户表和全局索引\n- 调用 `save_account(account_id)`\n- 返回 user key\n\n**`remove_user(account_id, user_id)`**：\n- 从 account 用户表和全局索引中移除\n- 调用 `save_account(account_id)`\n\n**`regenerate_key(account_id, user_id) -> str`**：\n- 删除旧 key 的全局索引\n- 生成新随机 key\n- 更新用户表和全局索引\n- 调用 `save_account(account_id)`\n- 返回新 key\n\n**`set_role(account_id, user_id, role)`**：\n- 更新用户角色（仅 ROOT 可调用）\n- 更新全局索引中的 role\n- 调用 `save_account(account_id)`\n\n---\n\n#### T4: 认证中间件重写\n\n**重写** `openviking/server/auth.py`，依赖：T1, T2, T3\n\n删除现有的 `verify_api_key()`、`get_user_header()`、`get_agent_header()`，替换为：\n\n**`resolve_identity(request, x_api_key, authorization, x_openviking_agent) -> ResolvedIdentity`**：\n```\n1. api_key_manager = request.app.state.api_key_manager\n2. 若 api_key_manager 为 None（dev 模式，未配置 root_api_key）：\n   返回 ResolvedIdentity(role=ROOT, account_id=\"default\", user_id=\"default\", agent_id=\"default\")\n3. 提取 key（同现有逻辑：X-API-Key 或 Bearer）\n4. identity = api_key_manager.resolve(key)\n   - 先 HMAC 比对 root key → 匹配则 role=ROOT\n   - 再查 user key 索引 → 匹配则得到 account_id, user_id, role(ADMIN/USER)\n   - 均不匹配 → 401\n5. identity.agent_id = x_openviking_agent or \"default\"\n6. 返回 identity\n```\n\n**`get_request_context(identity: ResolvedIdentity = Depends(resolve_identity)) -> RequestContext`**：\n```\naccount_id = identity.account_id or \"default\"\nuser_id = identity.user_id or \"default\"\nagent_id = identity.agent_id or \"default\"\nreturn RequestContext(\n    user=UserIdentifier(account_id, user_id, agent_id),\n    role=identity.role,\n)\n```\n\n**`require_role(*allowed_roles) -> dependency`**：\n```python\ndef require_role(*allowed_roles: Role):\n    async def _check(ctx: RequestContext = Depends(get_request_context)):\n        if ctx.role not in allowed_roles:\n            raise PermissionDeniedError(f\"Requires role: {allowed_roles}\")\n        return ctx\n    return _check\n```\n\n---\n\n#### T5: App 初始化集成\n\n**修改** `openviking/server/app.py`，依赖：T2, T4\n\n改动点在 `create_app()` 和 `lifespan()`：\n\n```python\n# 改前\napp.state.api_key = config.api_key\n\n# 改后\nif config.root_api_key:\n    #

Context 对象增加 account_id 和 owner_space\n\n`openviking/core/context.py` 中 `Context` 类需增加两个字段：\n\n```python\naccount_id: str = \"\"      # 所属 account\nowner_space: str = \"\"     # 所有者的 user_space_name() 或 agent_space_name()\n```\n\n`to_dict()` 输出包含这两个字段，`EmbeddingMsgConverter.from_context()` 无需改动即可透传到 VectorDB。\n\n上游构造 Context 时需从 RequestContext 填入这两个字段：\n- `ResourceService` / `SkillProcessor` → `account_id=ctx.account_id`, `owner_space=ctx.user.user_space_name()` 或 `agent_space_name()`（取决于 scope）\n- `MemoryExtractor.create_memory()` → 同上\n- `DirectoryInitializer._ensure_directory()` → 同上\n\n##### 8b. HierarchicalRetriever 注入多级过滤\n\n`retrieve/hierarchical_retriever.py` 的 `retrieve()` 方法需接受 `ctx: RequestContext` 参数，根据角色构造不同粒度的过滤条件（见第五节 5.5）：\n\n```python\nasync def retrieve(self, query: TypedQuery, ctx: RequestContext, ...) -> QueryResult:\n    filters = []\n    if ctx.role == Role.ADMIN:\n        filters.append({\"op\": \"must\", \"field\": \"account_id\", \"conds\": [ctx.account_id]})\n    elif ctx.role == Role.USER:\n        filters.append({\"op\": \"must\", \"field\": \"account_id\", \"conds\": [ctx.account_id]})\n        filters.append({\"op\": \"must\", \"field\": \"owner_space\",\n                        \"conds\": [ctx.user.user_space_name(), ctx.user.agent_space_name()]})\n    # ROOT 无过滤\n```\n\n调用方（`VikingFS.find()`, `VikingFS.search()`）从 ctx 传入。\n\n---\n\n#### T9: Service 层适配\n\n**修改文件**：`service/core.py` 及 `service/fs_service.py`, `service/search_service.py`, `service/session_service.py`, `service/resource_service.py`, `service/relation_service.py`, `service/pack_service.py`, `service/debug_service.py`，依赖：T1, T6\n\n##### 核心变更：去除 `_user` 单例\n\n`OpenVikingService.__init__()` 中删除 `self._user`。\n`set_dependencies()` 调用中删除 `user=self.user` 参数。\n\n##### 各 sub-service 改动模式\n\n所有 sub-service 当前的模式是：\n```python\nclass XXXService:\n    def set_dependencies(self, viking_fs, ..., user=None):\n        self._viking_fs = viking_fs\n        self._user = user  # ← 删除\n\n    async def some_method(self, ...):\n        # 使用 self._viking_fs 和 self._user\n```\n\n改为：\n```python\nclass XXXService:\n    def set_dependencies(self, viking_fs, ...):  # 去掉 user\n        self._viking_fs = viking_fs\n\n    async def some_method(self, ..., ctx: RequestContext):  # 加 ctx\n        # 使用 self._viking_fs 和 ctx\n```\n\n##### 逐 service 改动清单\n\n**FSService**（`service/fs_service.py`）：\n- 当前：`ls(uri)`, `tree(uri)`, `stat(uri)`, `mkdir(uri)`, `rm(uri)`, `mv(old, new)`, `read(uri)`, `abstract(uri)`, `overview(uri)`, `grep(uri, pattern)`, `glob(pattern, uri)`\n- 改为：所有方法加 `ctx` 参数，传递给 VikingFS 调用\n\n**SearchService**（`service/search_service.py`）：\n- 当前：`find(query, ...)`, `search(query, ...)`\n- 改为：加 `ctx`，传给 VikingFS.find/search\n\n**SessionService**（`service/session_service.py`）：\n- 当前：`session(session_id)`, `sessions()`, `delete(session_id)`, `extract(session_id)` 使用 `self._user`\n- 改为：加 `ctx`，构造 Session 时从 ctx 获取 user，extract 时传 ctx.user 给 compressor\n- session 路径变为 `viking://session/{ctx.user.user_space_name()}/{session_id}`\n\n**ResourceService**（`service/resource_service.py`）：\n- 当前：`add_resource(...)`, `add_skill(...)` 使用 `self._user`\n- 改为：加 `ctx`，构造 Context 时填入 `account_id=ctx.account_id`, `owner_space=ctx.user.agent_space_name()`（agent scope）\n- 资源路径使用 `viking://resources/...`（account 内共享，无 user_space），技能路径使用 `viking://agent/skills/{ctx.user.agent_space_name()}/...`\n\n**RelationService**（`service/relation_service.py`）：\n- 当前：`relations(uri)`, `link(from, to)`, `unlink(from, to)`\n- 改为：加 `ctx`，传给 VikingFS\n\n**PackService**（`service/pack_service.py`）：\n- 当前：`export_ovpack(uri)`, `import_ovpack(data)`\n- 改为：加 `ctx`，传给 VikingFS\n\n**DebugService**（`service/debug_service.py`）：\n- 当前：`get_status()`, `observer` 等系统级方法\n- 改为：部分方法可能不需要 ctx（如 health check），但 observer 需要\n\n---\n\n#### T13: 目录初始化适配\n\n**修改文件**：`core/directories.py`，依赖：T6, T8\n\n##### 核心改动\n\n`DirectoryInitializer` 当前在 `service.initialize()` 中调用，初始化全局预设目录。多租户后改为三种初始化时机：\n\n1. **创建新 account 时**（Admin API T11）→ 初始化该 account 的公共根目录（`viking://user`、`viking://agent`、`viking://resources` 等）\n2. **用户首次访问时** → 懒初始化 user space 子目录（`viking://user/{user_space}/memories/preferences` 等）\n3. **agent 首次使用时** → 懒初始化 agent space 子目录（`viking://agent/{agent_space}/memories/cases` 等）\n\n方法签名改为接受 `ctx: RequestContext`：\n\n```python\nasync def initialize_account_directories(self, ctx: RequestContext) -> int:\n    \"\"\"初始化 account 级公共根目录\"\"\"\n    ...\n\nasync def initialize_user_directories(self, ctx: RequestContext) -> int:\n    \"\"\"初始化 user space 子目录\"\"\"\n    ...\n\nasync def initialize_agent_directories(self, ctx: RequestContext) -> int:\n    \"\"\"初始化 agent space 子目录\"\"\"\n    ...\n```\n\n`_ensure_directory` 和 `_create_agfs_structure` 中需要：\n- 通过 ctx 传入 account_id 给 VikingFS\n- 构造 Context 时填入 `account_id` 和 `owner_space`，写入 VectorDB 的记录也包含这两个字段\n\n---\n\n#### T15: 数据迁移脚本\n\n**新建** `openviking/cli/migrate.py`，依赖：T6, T7\n\n提供 `python -m openviking migrate` 命令，将旧版单租户数据迁移到多租户路径结构。\n\n##### 迁移逻辑\n\n1. **检测**：检查旧结构是否存在（`/local/resources/` 存在但 `/local/default/` 不存在）\n2. **AGFS 搬迁**：\n   -

Root Key 创建工作区（含首个 admin）→ Admin 注册 user → User Key 操作数据 → 验证隔离\n   - 删除用户后旧 user key 失败\n   - 删除 account 后级联清理数据\n   - Dev 模式（无 root_api_key）正常工作，使用 default account\n4. **回归测试**：现有测试适配新认证流程（使用 dev mode）\n\n---\n\n## 待评审决策项（TODO）\n\n以下设计点在 V2 评审中已全部确定：\n\n1. ~~**User Key 方案选型**（见 2.2 节）~~ —— 已确定：方案 B（随机 key + 查表），不需要 `private_key`。\n2. ~~**Agent 目录归属模型**（见 4.3 节）~~ —— 已确定：方案 B（按 user_id + agent_id 隔离）。\n3. ~~**单租户兼容**（见 8 节）~~ —— 已确定：破坏性改造，不保留单租户模式。\n\n所有待评审项已解决，无遗留决策。\n\n---\n\n## 评审记录\n\n### 2026-02-13\n\n#### 设计决策确定\n\n1. **去掉 Account Key**：三层 Key（root/account/user）简化为两层（root/user）。ADMIN 不再由 key 类型决定，而是用户在 account 内的角色属性，存储在 `users.json` 中。一个 account 可以有多个 admin。\n2. **Account = 工作区**：Account 是由 ROOT 创建的工作区（workspace）。`/_system/accounts.json` 维护全局工作区列表，每个工作区有独立的用户注册表 `/{account_id}/_system/users.json`。系统启动时自动创建 default 工作区。\n3. **User Key 方案 B**：随机 key + 查表存储。不需要 `private_key` 配置，不需要加密库。key 丢失后重新生成，旧 key 立即失效。\n4. **Agent 目录方案 B**：按 user_id + agent_id 隔离。`agent_space_name()` = `md5(user_id + agent_id)[:12]`，每个用户与 agent 的组合有独立数据空间。\n5. **破坏性改造**：不保留单租户模式，统一多租户路径结构。所有 account（含 default）使用 `/{account_id}/...` 层级路径。\n6. **嵌入模式支持多租户**：通过构造参数传入 `UserIdentifier`，默认使用 default 工作区 + default 用户。\n7. **API Key 无前缀**：所有 key 为纯随机 token（`secrets.token_hex(32)`），不携带身份信息。服务端通过先比对 root key、再查 user key 索引的方式确定身份。\n8. **Resources account 级共享**：resources 在 account 内共享，不按 user_space 隔离。路径为 `/{account_id}/resources/...`。\n9. **ROOT 支持全部功能**：ROOT 权限为超集，既能做管理操作也能使用常规产品功能。dev 模式默认 ROOT 角色。\n10. **配置简化**：`ov.conf` server 段移除 `private_key` 和 `multi_tenant`，仅保留 `root_api_key` 和 `cors_origins`。\n11. **创建 account 同时指定首个 admin**：`POST /admin/accounts` 一步完成工作区创建 + 首个 admin 注册 + 返回 user key。\n12. **队列/Observer account 级可见性**：底层单例，查询时按 account_id 过滤。放在 Phase 2。\n\n#### 新增任务\n\n- **T15**：数据迁移脚本（`python -m openviking migrate`），将旧版单租户数据迁移到多租户路径结构，Phase 2 实现\n- **T16-P1**：Phase 1 用户文档更新（配置、认证、部署、API 概览、快速开始）\n- **T16-P2**：Phase 2 用户文档更新（架构、存储、URI、变更日志）\n- **T17-P1**：Phase 1 示例更新（config 文件 + 多租户管理工作流示例）\n- **T17-P2**：Phase 2 示例更新（数据隔离验证 + agent 共享验证示例）\n\n#### Key 存储方案\n\n评审讨论了 key 存储结构的三种方案（user_id 做主键 / key 做主键 / 双索引），确定采用方案 A（user_id 做主键）。文件结构用于持久化和人工排查，运行时认证全走内存索引（`dict[key] → identity`），O(1) 查找。\n\n\n"

    "content": "# OpenClaw Context Engine Integration Design / OpenClaw 上下文引擎集成方案设计\n\n## Context / 背景\n\n本方案讨论在 OpenViking 中集成 OpenClaw Context Engine 的扩展机制，以及围绕新引擎的记忆管理、查询、注入等完整设计。\n\nThis proposal discusses the extension mechanism for integrating OpenClaw Context Engine into OpenViking, along with the complete design for memory management, retrieval, and injection around the new engine.\n\n---\n\n## Component 1: Memory Write Mechanism / 组件 1：记忆写入机制\n\n### Compact-Triggered Automatic Write / compact 触发的自动写入\n\n1. 当 compact 时一次性把对话上传到 ov。\n\n   Upload conversation to OpenViking in one batch when compact is triggered.\n\n2. 可选项：compact 时，可以把一些工作记忆（比如 TODO，摘要），留在压缩后的上下文里面（如果有的话），避免断档。\n\n   Optional: During compact, keep some working memories (e.g., TODOs, summaries) in the compressed context (if available) to avoid discontinuity.\n\n3. 由于涉及 agent 记忆的提取，建议把 system prompt 和工具调用也一起上传。\n\n   Since agent memory extraction is involved, it is recommended to also upload the system prompt and tool calls together.\n\n4. 相比于之前模式（每条消息都写入），一次性的写入可以减少记忆提取阶段的 token 消耗，带来的缺点是跨 session 的记忆同步会变慢（不敏感）。\n\n   Compared to the previous mode (writing every message), one-time writing reduces token consumption during memory extraction. The downside is that cross-session memory synchronization will be slower (not sensitive).\n\n5. compact 一般在 /new 或消息达到一定长度时触发，消息未达长度的部分不会触发记忆提取。这部分未来可以加入 timeout 触发提取的机制（当前可以不要）。\n\n   Compact is typically triggered by /new or when messages reach a certain length. Messages that don't reach the length threshold won't trigger memory extraction. A timeout-based extraction mechanism can be added in the future (not needed currently).\n\n---\n\n### Active Memory (Tool-based) / 主动记忆（基于工具）（可选）\n\n这允许 agent 通过 `commit_memory` 工具（或ov cli）主动记录记忆，支持用户请求如：\n\nThis allows the agent to actively record memories via a `commit_memory` tool (or ov cli), supporting user requests like:\n\n- \"Remember that I like dark mode\" / \"记住我喜欢深色模式\"\n- \"Don't ask me for confirmation again\" / \"下次不要再让我确认了\"\n- \"Note that project X is on hold\" / \"记下项目 X 暂停了\"\n\n**commit_memory Tool / 工具**:\n- **Purpose / 用途**: Actively commit a memory to long-term storage / 主动将记忆提交到长期存储\n- **When to use / 何时使用**: User asks to remember, strong preference, important decision, etc. / 用户要求记住、强烈偏好、重要决定等\n- **Parameters / 参数**: `memory_content`, `memory_type`, `priority`, `category`\n- **Behavior / 行为**: Immediate extraction and write (no compact delay) / 立即提取和写入（无 compact 延迟）\n\n---\n\n## Component 2: Memory Retrieval / 组件 2：记忆查询/召回\n\n记忆查询分为三部分：\n\nMemory retrieval has three parts:\n\n1. **用户画像注入** - 在会话开始时注入到 system prompt / User Profile Injection - Injected into system prompt at session start\n2. **每轮记忆召回** - 为每条用户消息召回相关记忆 / Per-turn Memory Retrieval - Retrieve relevant memories for each user message\n3. **Agent主动通过工具调用召回记忆**（TODO） / Agent-initiated memory retrieval via tool calls (TODO)\n\n---\n\n### Part 1: User Profile Injection / 第一部分：用户画像注入\n\n在会话开始时一次性注入到 system prompt。\n\nInjected once at session start into the system prompt.\n\n**Profile Sources / 画像来源**:\n- `profile.md` - User's main profile file (always included) / 用户主画像文件（总是包含）\n- High-quality memory abstracts (only if quality score >= threshold) / 高质量记忆摘要（TODO：是否加入取决于摘要机制的质量是否ok / TODO: inclusion depends on whether the quality of the abstraction mechanism is acceptable）\n\n---\n\n### Part 2: Per-turn Memory Retrieval / 第二部分：每轮记忆召回\n\n为每条用户消息召回，仅用于该次 LLM 调用。\n\nRetrieved for each user message, only used for that single LLM call.\n\n**Query Construction / 查询构建**: Use last N user messages (default: 5) concatenated as the search query / 使用最近 N 条用户消息（默认：5条）拼接作为搜索查询\n\n**Lightweight Intent Detection / 轻量级意图检测（TODO 可选模块，可基于轻量模型实现 / TODO optional module, can be implemented with lightweight models）**:\n- Skip retrieval for greetings (\"你好\", \"在吗\", \"hi\", \"hello\") / 跳过问候语的召回\n- Skip very short messages (<= 3 chars) / 跳过很短的消息（<= 3 字符）\n\n---\n\n**将自动召回的记忆作为模拟的 function call 结果注入，而不是直接注入到 prompt 中**\n\nInject auto-retrieved memories as simulated function call results instead of directly injecting into the prompt. This is a continuation of Part 2.\n\n**Benefits / 好处**:\n1. **Agent Awareness / Agent 感知**: The agent sees that a search was performed, so it knows this pattern exists and can use it itself later / Agent 看到执行了搜索，因此知道这种模式存在，以后可以自己使用\n2. **Query Transparency / 查询透明**: The agent sees exactly what query was used, so it can choose different keywords if it searches again / Agent 看到具体使用了什么查询，因此如果再次搜索可以选择不同的关键词\n\n**Example Flow / 示例流程**:\n```\nUser: How do I optimize the database?\n\nAssistant: [Function Call] search_memories({\"query\": \"database optimization...\", \"max_results\": 5})\n\nSystem: [Function Result] {\"success\": true, \"memories\": [...]}\n\nAssistant: Based on...\n```\n\n**Retrieval Flow / 召回流程**:\n1. Get current user message / 获取当前用户消息\n2. Check if should skip retrieval / 检查是否应该跳过召回\n3. Build search query from last N user messages / 从最近 N 条用户消息构建搜索查询\n4. Search in OpenViking / 在 OpenViking 中搜索\n5. Apply relevance threshold filter / 应用相关性阈值过滤\n6. Format memories (L0/L1/L2 based on config) / 格式化记忆（根据配置使用 L0/L1/L2）\n7. Inject into THIS LLM call only (not persisted) / 仅注入到本次 LLM 调用（不持久化）\n\n---\n\n## Component 3: Agentic Memory Query / 组件 3：Agent 通过工具主动记忆查询\n\n除了每轮自动注入之外，还提供 Agent 发起的查询机制，以满足更复杂的检索需求。这是一种\"测试时计算\"的方法，用于解决单轮回召可能遗漏的多跳和多背景检索问题。\n\nIn addition to per-turn auto-injection, provide an agent-initiated query mechanism to meet more complex retrieval needs. This is a \"test-time compute\" approach to solve multi-hop and multi-context retrieval problems that single-round retrieval may miss.\n\n### Pre-inject Directory Structure / 预先注入目录结构\n\n为了让主动记忆的路径尽可能短，可以默认把 `ov ls viking://` 的结果预先注入到 system prompt 里面，让 agent 预先知道 ov 里有哪些数据可以用。如果能模拟成是 agent 主动调用的，效果可能更好。\n\nTo make the path to active memory as short as possible, pre-inject the results of `ov ls viking://` into the system prompt by default, so the agent knows in advance what data is available in OpenViking. Effect may be better if simulated as an agent-initiated call.\n\n**Design / 设计**:\n- At session start / 在会话开始时\n- Run `ov ls viking://` (or equivalent) / 运行 `ov ls viking://`（或等效操作）\n- Format results as directory tree / 将结果格式化为目录树\n- Inject into system prompt, optionally simulate as function call / 注入到 system prompt，可选模拟为 function call\n\n**Example / 示例**:\n```\nAssistant: [Function Call] ov_ls({\"path\": \"viking://\"})\n\nSystem: [Function Result] {\n  \"directories\": [\n    \"viking://docs/\",\n    \"viking://user/memories/\",\n    \"viking://agent/skills/\",\n    \"viking://assets/\"\n  ]\n}\n```\n\n### When to Use / 何时使用\n\n| Scenario / 场景 | Example / 示例 |\n|----------------|---------------|\n| **Multi-hop reasoning / 多跳推理** | \"What did I say about project X last week, and how does that relate to the Y file we discussed?\" |\n| **Need for comprehensive context / 需要全面上下文** | \"Tell me everything I've said about database optimization\" |\n| **Temporal queries / 时间查询** | \"What decisions did we make in the last month about authentication?\" |\n| **Cross-session retrieval / 跨会话检索** | \"Find my previous conversation about API design patterns\" |\n| **Directory semantic exploration / 目录语义探索** | \"What's in the /docs folder that's relevant to my current task?\" |\n\n---\n\n## Component 4: Skill Memory Injection / 组件 4：Skill 记忆注入\n\nSkill 记忆是Agent记忆的一种，区别点在于他锚定一个确定性的Skill\n\n因此可以通过拦截工具调用中的 `read skills/xxx/SKILL.md` 文件调用，在返回结果中添加 skill 记忆的方式注入。\n\nSkill memories are a type of agent memory, with the key distinction that they are anchored to a specific skill.\n\nTherefore, they can be injected by intercepting `read skills/xxx/SKILL.md` file calls in tool calls, and adding skill memories to the returned results.\n\n**Design / 设计**:\n\n1. **Intercept skill file reads / 拦截 skill 文件读取**\n   - When agent reads `skills/<skill_name>/SKILL.md` / 当 agent 读取 `skills/<skill_name>/SKILL.md` 时\n   - Intercept the read operation / 拦截读取操作\n   - Look up skill memories from memory store / 从记忆存储中查找 skill 记忆\n\n2. **Augment skill content / 增强 skill 内容**\n   - Prepend/append skill memories to the SKILL.md content / 在 SKILL.md 内容前后添加 skill 记忆\n   - Include usage patterns, success tips, common pitfalls, etc. / 包含使用模式、成功技巧、常见陷阱等\n   - Keep the original SKILL.md intact / 保持原始 SKILL.md 不变\n\n3. **Skill memory structure / Skill 记忆结构**\n   - Usage statistics (how often used, success rate) / 使用统计（使用频率、成功率）\n   - Past examples (successful invocations) / 过去的示例（成功调用）\n   - Tips and tricks (learned from experience) / 技巧和窍门（从经验中学习）\n   - Known issues and workarounds / 已知问题和解决方法\n\n**Example / 示例**:\n```\nOriginal SKILL.md:\n## Create Presentation\nCreate a PowerPoint presentation...\n\nAugmented with skill memory:\n## Create Presentation (Used 15 times, 93% success)\n\nCreate a PowerPoint presentation...\n\n---\n## Past Examples\n- Successfully created Q3 financial report (2024-03-01)\n- Created project kickoff deck (2024-02-15)\n\n## Tips\n- User prefers dark theme templates\n- Always include executive summary slide\n- Use company logo from /assets/logo.png\n\n## Known Issues\n- Large images (>10MB) sometimes fail - compress first\n```\n\n---\n\n## Component 5: Tool Memory Injection / 组件 5：工具记忆注入\n\n工具记忆可以通过 system prompt 方式注入。\n\nTool memories can be injected via system prompt.\n\n**Design / 设计**:\n\n1. **Inject into system prompt / 注入到 system prompt**\n   - At the start of each session or turn / 在每个会话或轮次开始时\n   - Include tool usage memories / 包含工具使用记忆\n   - Keep it concise to avoid token bloat / 保持简洁以避免 token 膨胀\n\n2. **Tool memory content / 工具记忆内容**\n   - Tool usage statistics (call count, success rate, average time) / 工具使用统计（调用次数、成功率、平均时间）\n   - Common parameter patterns / 常见参数模式\n   - Error patterns and how to avoid them / 错误模式和如何避免\n   - Best practices learned / 学到的最佳实践\n\n3. **Format / 格式**\n   - Structured, easy to parse / 结构化，易于解析\n   - Priority-based (most important first) / 基于优先级（最重要的在前）\n   - Include only high-value insights / 仅包含高价值洞察\n\n**Example / 示例**:\n```\n## Tool Usage Memories\n\n### run_shell\n- Called 42 times, 88% success rate\n- Average time: 2.3s\n- Common issues:\n  - Forgetting to use `cd` before relative paths\n  - Long-running commands need `--async` flag\n- Best practice: Always use `&&` for chained commands\n\n### edit_file\n- Called 156 times, 95% success rate\n- Best practice: Use `search_replace` instead of full rewrite when possible\n```\n\n---\n\n## Appendix: OpenViking Tool Injection / 附录：OpenViking 工具注入\n\n本节讨论如何将 OpenViking 能力注入到 Agent 中。提出了两种方案，都避免了基于 skill 的注入模式。\n\nThis section discusses how to inject OpenViking capabilities into the agent. Two options are proposed, both avoiding the skill-based injection pattern.\n\n### Problem with Skill-based Injection / 基于 Skill 注入的问题\n\n- **Unstable triggering / 触发不稳定**\n- **Competition with other skills / 需要和其他 skill 竞争**\n- **Hard to predict when it will be used / 难以预测何时会被使用**\n\n---\n\n### Option 1: System Prompt + Bash CLI (Recommended if CLI is LLM-friendly) / 方案 1：System Prompt + Bash CLI（如果 CLI 对 LLM 友好，推荐此方案）\n\n直接将 OpenViking CLI 用法说明注入到 system prompt 中。Agent 使用内置的 bash 工具调用 `ov` 命令。\n\nInject OpenViking CLI usage instructions directly into the system prompt. The agent uses the built-in bash tool to call `ov` commands.\n\n**Advantages / 优势**:\n- No tool definition needed / 不需要定义 tool\n- Uses agent's existing bash capabilities / 使用 Agent 已有的 bash 能力\n- More flexible (agent can compose commands) / 更灵活（Agent 可以组合命令）\n- Works well if CLI is simple and intuitive / 如果 CLI 简单直观，效果很好\n\n**Requirements / 要求**:\n- CLI must be LLM-friendly (simple commands, good help text) / CLI 必须对 LLM 友好（命令简单、帮助文本完善）\n- Predictable output format (JSON by default) / 可预测的输出格式（默认 JSON）\n- Clear, self-documenting commands / 清晰、自解释的命令\n\n**Example Commands / 示例命令**:\n```bash\nov search --query \"your query\" [--category <category>] [--limit N]\nov ls memories [--category <category>]\nov search-docs --query \"your query\" [--path <directory>]\nov history [--limit N]\nov remember --content \"what to remember\" [--type <type>] [--priority N]\n```\n\n---\n\n### Option 2: Tool Definition Injection / 方案 2：工具定义注入\n\n将 OpenViking 能力定义为显式的工具定义（function calling）。\n\nDefine OpenViking capabilities as explicit tool definitions (function calling).\n\n**Advantages / 优势**:\n- More predictable triggering / 触发更可预测\n- Structured input validation / 结构化输入验证\n- Clear separation from bash usage / 与 bash 用法清晰分离\n- Works even if agent doesn't have bash access / 即使 Agent 没有 bash 访问权限也能工作\n\n**Disadvantages / 劣势**:\n- Need to maintain tool definitions / 需要维护工具定义\n- Less flexible than free-form bash / 不如自由形式的 bash 灵活\n- More verbose for complex operations / 复杂操作更冗长\n\n---\n\n### Comparison / 对比\n\n| Aspect / 方面 | Option 1: System Prompt + Bash / 方案 1：System Prompt + Bash | Option 2: Tool Definition / 方案 2：工具定义 |\n|--------------|----------------------------------------------------------------|----------------------------------------------|\n| **Trigger Stability / 触发稳定性** | Depends on bash tool reliability / 取决于 bash 工具可靠性 | More predictable / 更可预测 |\n| **Flexibility / 灵活性** | High - can compose commands / 高 - 可以组合命令 | Lower - fixed schema / 较低 - 固定 schema |\n| **Maintenance / 维护成本** | Maintain CLI help text / 维护 CLI 帮助文本 | Maintain tool definitions / 维护工具定义 |\n| **LLM Friendliness / LLM 友好度** | Requires good CLI design / 需要好的 CLI 设计 | Explicit schema helps / 显式 schema 有帮助 |\n| **Bash Required / 需要 Bash** | Yes / 是 | No / 否 |\n\n---\n\n### Recommendation / 建议\n\n**Primary Recommendation: Option 1 (CLI + Bash) if CLI can be made LLM-friendly**\n\n**主要建议：如果 CLI 能做到对 LLM 友好，选择方案 1（CLI + Bash）**\n\nWhy / 为什么：\n1. More flexible for power users / 对高级用户更灵活\n2. Single source of truth (CLI works for humans and agents) / 单一事实来源（CLI 对人类和 Agent 都有效）\n3. Less code to maintain (no duplicate tool definitions) / 维护代码更少（没有重复的工具定义）\n4. Agents can discover and experiment with commands / Agent 可以发现和实验命令\n\n**Fallback: Option 2 (Tool Definition) if CLI can't be simplified enough**\n\n**备选方案：如果 CLI 无法足够简化，选择方案 2（工具定义）**\n\n---\n"

    "content": "# API Overview\n\nThis page covers how to connect to OpenViking and the conventions shared across all API endpoints.\n\n## Connecting to OpenViking\n\nOpenViking supports three connection modes:\n\n| Mode | Use Case | Description |\n|------|----------|-------------|\n| **Embedded** | Local development, single process | Runs locally with local data storage |\n| **HTTP** | Connect to OpenViking Server | Connects to a remote server via HTTP API |\n| **CLI** | Shell scripting, agent tool-use | Connects to server via CLI commands |\n\n### Embedded Mode\n\n```python\nimport openviking as ov\n\nclient = ov.OpenViking(path=\"./data\")\nclient.initialize()\n```\n\nEmbedded mode uses `ov.conf` to configure embedding, vlm, storage, and other modules. Default path: `~/.openviking/ov.conf`. You can also specify the path via environment variable:\n\n```bash\nexport OPENVIKING_CONFIG_FILE=/path/to/ov.conf\n```\n\nMinimal configuration example:\n\n```json\n{\n  \"embedding\": {\n    \"dense\": {\n      \"api_base\": \"<api-endpoint>\",\n      \"api_key\": \"<your-api-key>\",\n      \"provider\": \"<volcengine|openai|jina>\",\n      \"dimension\": 1024,\n      \"model\": \"<model-name>\"\n    }\n  },\n  \"vlm\": {\n    \"api_base\": \"<api-endpoint>\",\n    \"api_key\": \"<your-api-key>\",\n    \"provider\": \"<volcengine|openai|jina>\",\n    \"model\": \"<model-name>\"\n  }\n}\n```\n\nFor full configuration options and provider-specific examples, see the [Configuration Guide](../guides/01-configuration.md).\n\n### HTTP Mode\n\n```python\nclient = ov.SyncHTTPClient(\n    url=\"http://localhost:1933\",\n    api_key=\"your-key\",\n    agent_id=\"my-agent\",\n    timeout=120.0,\n)\nclient.initialize()\n```\n\nWhen `url` is not explicitly provided, the HTTP client automatically loads connection info from `ovcli.conf`. This config file is shared between the HTTP client and CLI. Default path: `~/.openviking/ovcli.conf`. You can also specify the path via environment variable:\n\n```bash\nexport OPENVIKING_CLI_CONFIG_FILE=/path/to/ovcli.conf\n```\n\n```json\n{\n  \"url\": \"http://localhost:1933\",\n  \"api_key\": \"your-key\",\n  \"agent_id\": \"my-agent\"\n}\n```\n\n| Field | Description | Default |\n|-------|-------------|---------|\n| `url` | Server address | (required) |\n| `api_key` | API key | `null` (no auth) |\n| `timeout` | HTTP request timeout in seconds | `60.0` |\n| `output` | Default output format: `\"table\"` or `\"json\"` | `\"table\"` |\n\nSee the [Configuration Guide](../guides/01-configuration.md#ovcliconf) for details.\n\n### Direct HTTP (curl)\n\n```bash\ncurl http://localhost:1933/api/v1/fs/ls?uri=viking:// \\\n  -H \"X-API-Key: your-key\"\n```\n\n### CLI Mode\n\nThe CLI connects to an OpenViking server and exposes all operations as shell commands. The CLI also loads connection info from `ovcli.conf` (shared with the HTTP client).\n\n**Basic Usage**\n\n```bash\nopenviking [global options] <command> [arguments] [command options]\n```\n\n**Global Options** (must be placed before the command name)\n\n| Option | Description |\n|--------|-------------|\n| `--output`, `-o` | Output format: `table` (default), `json` |\n| `--version` | Show CLI version |\n\nExample:\n\n```bash\nopenviking -o json ls viking://resources/\n```\n\n## Lifecycle\n\n**Embedded Mode**\n\n```python\nimport openviking as ov\n\nclient = ov.OpenViking(path=\"./data\")\nclient.initialize()\n\n# ... use client ...\n\nclient.close()\n```\n\n**HTTP Mode**\n\n```python\nimport openviking as ov\n\nclient = ov.SyncHTTPClient(url=\"http://localhost:1933\")\nclient.initialize()\n\n# ... use client ...\n\nclient.close()\n```\n\n## Authentication\n\nSee [Authentication Guide](../guides/04-authentication.md) for full details.\n\n- **X-API-Key** header: `X-API-Key: your-key`\n- **Bearer** header: `Authorization: Bearer your-key`\n- If no API key is configured on the server, authentication is skipped.\n- The `/health` endpoint never requires authentication.\n\n## Response Format\n\nAll HTTP API responses follow a unified format:\n\n**Success**\n\n```json\n{\n  \"status\": \"ok\",\n  \"result\": { ... },\n  \"time\": 0.123\n}\n```\n\n**Error**\n\n```json\n{\n  \"status\": \"error\",\n  \"error\": {\n    \"code\": \"NOT_FOUND\",\n    \"message\": \"Resource not found: viking://resources/nonexistent/\"\n  },\n  \"time\": 0.01\n}\n```\n\n## CLI Output Format\n\n### Table Mode (default)\n\nList data is rendered as tables; non-list data falls back to formatted JSON:\n\n```bash\nopenviking ls viking://resources/\n# name          size  mode  isDir  uri\n# .abstract.md  100   420   False  viking://resources/.abstract.md\n```\n\n### JSON Mode (`--output json`)\n\nAll commands output formatted JSON matching the API response `result` structure:\n\n```bash\nopenviking -o json ls viking://resources/\n# [{ \"name\": \"...\", \"size\": 100, ... }, ...]\n```\n\nThe default output format can be set in `ovcli.conf`:\n\n```json\n{\n  \"url\": \"http://localhost:1933\",\n  \"output\": \"json\"\n}\n```\n\n### Script Mode (`-o json`)\n\nCompact JSON with status wrapper (when `--compact` is true, which is the default), suitable for scripting:\n\n**Success**\n\n```json\n{\"ok\": true, \"result\": ...}\n```\n\n**Error**\n\n```json\n{\"ok\": false, \"error\": {\"code\": \"NOT_FOUND\", \"message\": \"Resource not found\", \"details\": {}}}\n```\n\n### Special Cases\n\n- **String results** (`read`, `abstract`, `overview`): printed directly as plain text\n- **None results** (`mkdir`, `rm`, `mv`): no output\n\n### Exit Codes\n\n| Code | Meaning |\n|------|---------|\n| 0 | Success |\n| 1 | General error |\n| 2 | Configuration error |\n| 3 | Connection error |\n\n## Error Codes\n\n| Code | HTTP Status | Description |\n|------|-------------|-------------|\n| `OK` | 200 | Success |\n| `INVALID_ARGUMENT` | 400 | Invalid parameter |\n| `INVALID_URI` | 400 | Invalid Viking URI format |\n| `NOT_FOUND` | 404 | Resource not found |\n| `ALREADY_EXISTS` | 409 | Resource already exists |\n| `UNAUTHENTICATED` | 401 | Missing or invalid API key |\n| `PERMISSION_DENIED` | 403 | Insufficient permissions |\n| `RESOURCE_EXHAUSTED` | 429 | Rate limit exceeded |\n| `FAILED_PRECONDITION` | 412 | Precondition failed |\n| `DEADLINE_EXCEEDED` | 504 | Operation timed out |\n| `UNAVAILABLE` | 503 | Service unavailable |\n| `INTERNAL` | 500 | Internal server error |\n| `UNIMPLEMENTED` | 501 | Feature not implemented |\n| `EMBEDDING_FAILED` | 500 | Embedding generation failed |\n| `VLM_FAILED` | 500 | VLM call failed |\n| `SESSION_EXPIRED` | 410 | Session no longer exists |\n\n## API Endpoints\n\n### System\n\n| Method | Path | Description

|\n|--------|----------------|------------------|\n| **Client** | Unified entry | Provides all operation interfaces, delegates to Service layer |\n| **Service** | Business logic | FSService, SearchService, SessionService, ResourceService, RelationService, PackService, DebugService |\n| **Retrieve** | Context retrieval | Intent analysis (IntentAnalyzer), hierarchical retrieval (HierarchicalRetriever), Rerank |\n| **Session** | Session management | Message recording, usage tracking, session compression, memory commit |\n| **Parse** | Context extraction | Document parsing (PDF/MD/HTML), tree building (TreeBuilder), async semantic generation |\n| **Compressor** | Memory compression | 6-category memory extraction, LLM deduplication decisions |\n| **Storage** | Storage layer | VikingFS virtual filesystem, vector index, AGFS integration |\n\n## Service Layer\n\nThe Service layer decouples business logic from the transport layer, enabling reuse across HTTP Server and CLI:\n\n| Service | Responsibility | Key Methods |\n|---------|----------------|-------------|\n| **FSService** | File system operations | ls, mkdir, rm, mv, tree, stat, read, abstract, overview, grep, glob |\n| **SearchService** | Semantic search | search, find |\n| **SessionService** | Session management | session, sessions, commit, delete |\n| **ResourceService** | Resource import | add_resource, add_skill, wait_processed |\n| **RelationService** | Relation management | relations, link, unlink |\n| **PackService** | Import/export | export_ovpack, import_ovpack |\n| **DebugService** | Debug service | observer (ObserverService) |\n\n## Dual-Layer Storage\n\nOpenViking uses a dual-layer storage architecture separating content from index (see [Storage Architecture](./05-storage.md)):\n\n| Layer | Responsibility | Content |\n|-------|----------------|---------|\n| **AGFS** | Content storage | L0/L1/L2 full content, multimedia files, relations |\n| **Vector Index** | Index storage | URIs, vectors, metadata (no file content) |\n\n## Data Flow Overview\n\n### Adding Context\n\n```\nInput → Parser → TreeBuilder → AGFS → SemanticQueue → Vector Index\n```\n\n1. **Parser**: Parse documents, create file and directory structure (no LLM calls)\n2. **TreeBuilder**: Move temp directory to AGFS, enqueue for semantic processing\n3. **SemanticQueue**: Async bottom-up L0/L1 generation\n4. **Vector Index**: Build index for semantic search\n\n### Retrieving Context\n\n```\nQuery → Intent Analysis → Hierarchical Retrieval → Rerank → Results\n```\n\n1. **Intent Analysis**: Analyze query intent, generate 0-5 typed queries\n2. **Hierarchical Retrieval**: Directory-level recursive search using priority queue\n3. **Rerank**: Scalar filtering + model reranking\n4. **Results**: Return contexts sorted by relevance\n\n### Session Commit\n\n```\nMessages → Compress → Archive → Memory Extraction → Storage\n```\n\n1. **Messages**: Accumulate conversation messages and usage records\n2. **Compress**: Keep recent N rounds, archive older messages\n3. **Archive**: Generate L0/L1 for history segments\n4. **Memory Extraction**: Extract 6-category memories from messages\n5. **Storage**: Write to AGFS + vector index\n\n## Deployment Modes\n\n### Embedded Mode\n\nFor local development and single-process applications:\n\n```python\nclient = OpenViking(path=\"./data\")\n```\n\n- Auto-starts AGFS subprocess\n- Uses local vector index\n- Singleton pattern\n\n### HTTP Mode\n\nFor team sharing, production deployment, and cross-language integration:\n\n```python\n# Python SDK connects to OpenViking Server\nclient = SyncHTTPClient(url=\"http://localhost:1933\", api_key=\"xxx\")\n```\n\n```bash\n# Or use curl / any HTTP client\ncurl http://localhost:1933/api/v1/search/find \\\n  -H \"X-API-Key: xxx\" \\\n  -d '{\"query\": \"how to use openviking\"}'\n```\n\n- Server runs as standalone process (`openviking-server`)\n- Clients connect via HTTP API\n- Supports any language that can make HTTP requests\n- See [Server Deployment](../guides/03-deployment.md) for setup\n\n## Design Principles\n\n| Principle | Description |\n|-----------|-------------|\n| **Pure Storage Layer** | Storage only handles AGFS operations and basic vector search; Rerank is in retrieval layer |\n| **Three-Layer Information** | L0/L1/L2 enables progressive detail loading, saving token consumption |\n| **Two-Stage Retrieval** | Vector search recalls candidates + Rerank improves accuracy |\n| **Single Data Source** | All content read from AGFS; vector index only stores references |\n\n## Related Documents\n\n- [Context Types](./02-context-types.md) - Resource/Memory/Skill types\n- [Context

    "content": "# Context Types\n\nBased on a simplified mapping of human cognitive patterns and engineering considerations, OpenViking abstracts context into **three basic types: Resource, Memory, and Skill**, each serving different purposes in Agent applications.\n\n## Overview\n\n| Type | Purpose | Lifecycle | Initiative |\n|------|---------|-----------|------------|\n| **Resource** | Knowledge and rules | Long-term, relatively static | User adds |\n| **Memory** | Agent's cognition | Long-term, dynamically updated | Agent records |\n| **Skill** | Callable capabilities | Long-term, static | Agent invokes |\n\n## Resource\n\nResources are external knowledge that Agents can reference.\n\n### Characteristics\n\n- **User-driven**: Resource information actively added by users to supplement LLM knowledge, such as product manuals and code repositories\n- **Static content**: Content rarely changes after addition, usually modified by users\n- **Structured storage**: Organized by project or topic in directory hierarchy, with multi-layer information extraction\n\n### Examples\n\n- API docs, product manuals\n- FAQ databases, code repositories\n- Research papers, technical specs\n\n### Usage\n\n```python\n# Add resource\nclient.add_resource(\n    \"https://docs.example.com/api.pdf\",\n    reason=\"API documentation\"\n)\n\n# Search resources\nresults = client.find(\n    \"authentication methods\",\n    target_uri=\"viking://resources/\"\n)\n```\n\n## Memory\n\nMemories are divided into user memories and Agent memories, representing learned knowledge about users and the world.\n\n### Characteristics\n\n- **Agent-driven**: Memory information actively extracted and recorded by Agent\n- **Dynamic updates**: Continuously updated from interactions by Agent\n- **Personalized**: Learned for specific users or specific Agents\n\n### 6 Categories\n\n| Category | Location | Description | Update Strategy |\n|----------|----------|-------------|-----------------|\n| **profile** | `user/memories/.overview.md` | User basic info | ✅ Appendable |\n| **preferences** | `user/memories/preferences/` | User preferences by topic | ✅ Appendable |\n| **entities** | `user/memories/entities/` | Entity memories (people, projects) | ✅ Appendable |\n| **events** | `user/memories/events/` | Event records (decisions, milestones) | ❌ No update |\n| **cases** | `agent/memories/cases/` | Learned cases | ❌ No update |\n| **patterns** | `agent/memories/patterns/` | Learned patterns | ❌ No update |\n\n### Usage\n\n```python\n# Memories are auto-extracted from sessions\nsession = client.session()\nawait session.add_message(\"user\", [{\"type\": \"text\", \"text\": \"I prefer dark mode\"}])\nawait session.commit()  # Extracts preference memory\n\n# Search memories\nresults = await client.find(\n    \"UI preferences\",\n    target_uri=\"viking://user/memories/\"\n)\n```\n\n## Skill\n\nSkills are capabilities that Agents can invoke, such as current Skills, MCP, etc.\n\n### Characteristics\n\n- **Defined capabilities**: Tool definitions for completing specific tasks\n- **Relatively static**: Skill definitions don't change at runtime, but usage memories related to tools are updated in memory\n- **Callable**: Agent decides when to use which skill\n\n### Storage Location\n\n```\nviking://agent/skills/{skill-name}/\n├── .abstract.md          # L0: Short description\n├── SKILL.md              # L1: Detailed overview\n└── scripts               # L2: Full definition\n```\n\n### Usage\n\n```python\n# Add skill\nawait client.add_skill({\n    \"name\": \"search-web\",\n    \"description\": \"Search the web for information\",\n    \"content\": \"# search-web\\n...\"\n})\n\n# Search skills\nresults = await client.find(\n    \"web search\",\n    target_uri=\"viking://agent/skills/\"\n)\n```\n\n## Unified Search\n\nBased on Agent's needs, supports unified search across all three context types, providing comprehensive information:\n\n```python\n# Search across all context types\nresults = await client.find(\"user authentication\")\n\nfor ctx in results.memories:\n    print(f\"Memory: {ctx.uri}\")\nfor ctx in results.resources:\n    print(f\"Resource: {ctx.uri}\")\nfor ctx in results.skills:\n    print(f\"Skill: {ctx.uri}\")\n```\n\n## Related Documents\n\n- [Architecture Overview](./01-architecture.md) - System architecture\n- [Context Layers](./03-context-layers.md) - L0/L1/L2 model\n- [Viking URI](./04-viking-uri.md) - URI specification\n- [Session Management](./08-session.md) - Memory extraction mechanism\n"

Returns temp directory URI\nparse_result.temp_dir_path  # viking://temp/abc123\n```\n\n### Smart Splitting\n\n```\nIf document_tokens <= 1024:\n    → Save as single file\nElse:\n    → Split by headers\n    → Section < 512 tokens → Merge\n    → Section > 1024 tokens → Create subdirectory\n```\n\n### Return Result\n\n```python\nParseResult(\n    temp_dir_path: str,    # Temp directory URI\n    source_format: str,    # pdf/markdown/html\n    parser_name: str,      # Parser name\n    parse_time: float,     # Duration (seconds)\n    meta: Dict,            # Metadata\n)\n```\n\n## TreeBuilder\n\nTreeBuilder moves temp directory to AGFS and queues semantic processing.\n\n### Core Flow\n\n```python\nbuilding_tree = tree_builder.finalize_from_temp(\n    temp_dir_path=\"viking://temp/abc123\",\n    scope=\"resources\",  # resources/user/agent\n)\n```\n\n### 5-Phase Processing\n\n1. **Find document root**: Ensure exactly 1 subdirectory in temp\n2. **Determine target URI**: Map base URI by scope\n3. **Recursively move directory tree**: Copy all files to AGFS\n4. **Clean up temp directory**: Delete temp files\n5. **Queue semantic generation**: Submit SemanticMsg to queue\n\n### URI Mapping\n\n| scope | Base URI |\n|-------|----------|\n| resources | `viking://resources` |\n| user | `viking://user` |\n| agent | `viking://agent` |\n\n## SemanticQueue\n\nSemanticQueue handles async L0/L1 generation and vectorization.\n\n### Message Structure\n\n```python\nSemanticMsg(\n    id: str,           # UUID\n    uri: str,          # Directory URI\n    context_type: str, # resource/memory/skill\n    status: str,       # pending/processing/completed\n)\n```\n\n### Processing Flow (Bottom-up)\n\n```\nLeaf directories → Parent directories → Root\n```\n\n### Single Directory Processing Steps\n\n1. **Concurrent file summary generation**: Limited to 10 concurrent\n2. **Collect child directory abstracts**: Read generated .abstract.md\n3. **Generate .overview.md**: LLM generates L1 overview\n4. **Extract .abstract.md**: Extract L0 from overview\n5. **Write files**: Save to AGFS\n6. **Vectorize**: Create Context and queue to EmbeddingQueue\n\n### Configuration Parameters\n\n| Parameter | Default | Description |\n|-----------|---------|-------------|\n| `max_concurrent_llm` | 10 | Concurrent LLM calls |\n| `max_images_per_call` | 10 | Max images per VLM call |\n| `max_sections_per_call` | 20 | Max sections per VLM call |\n\n## Code Skeleton Extraction (AST Mode)\n\nFor code files, OpenViking supports AST-based skeleton extraction via tree-sitter as a lightweight alternative to LLM summarization, significantly reducing processing cost.\n\n### Modes\n\nControlled by `code_summary_mode` in `ov.conf` (see [Configuration](../guides/01-configuration.md#code)):\n\n| Mode | Description |\n|------|-------------|\n| `\"ast\"` | Extract structural skeleton for files ≥100 lines, skip LLM calls (**default**) |\n| `\"llm\"` | Always use LLM for summarization (original behavior) |\n| `\"ast_llm\"` | Extract AST skeleton first, then pass it as context to LLM for summarization |\n\n### What AST Extracts\n\nThe skeleton includes:\n\n- Module-level docstring (first line)\n- Import statement list\n- Class names, base classes, and method signatures (`ast` mode: first-line docstrings only; `ast_llm` mode: full docstrings)\n- Top-level function signatures\n\n### Supported Languages\n\nThe following languages have dedicated extractors built on tree-sitter:\n\n| Language | Status |\n|----------|--------|\n| Python | Supported |\n| JavaScript / TypeScript | Supported |\n| Rust | Supported |\n| Go | Supported |\n| Java | Supported |\n| C / C++ | Supported |\n\nOther languages automatically fall back to LLM.\n\n### Fallback Behavior\n\nThe following conditions trigger automatic fallback to LLM, with the reason logged. The overall pipeline is unaffected:\n\n- Language not in the supported list\n- File has fewer than 100 lines\n- AST parse error\n- Extraction produces an empty skeleton\n\n### File Structure\n\n```\nopenviking/parse/parsers/code/ast/\n├── extractor.py      # Language detection and dispatch\n├── skeleton.py       # CodeSkeleton / FunctionSig / ClassSkeleton data structures\n└── languages/        # Per-language extractors\n```\n\n## Three Context Types Extraction\n\n### Flow Comparison\n\n| Phase | Resource | Memory | Skill |\n|-------|----------|--------|-------|\n| **Parser** | Common flow | Common flow | Common flow |\n| **Base URI** | `viking://resources` | `viking://user/memories` | `viking://agent/skills` |\n| **TreeBuilder scope** | resources | user/agent | agent |\n| **SemanticMsg type** | resource | memory | skill |\n\n### Resource Extraction\n\n```python\n# Add resource\nawait client.add_resource(\n    \"/path/to/doc.pdf\",\n    reason=\"API documentation\"\n)\n\n# Flow: Parser → TreeBuilder(scope=resources) → SemanticQueue\n```\n\n### Skill Extraction\n\n```python\n# Add skill\nawait client.add_skill({\n    \"name\": \"search-web\",\n    \"content\": \"# search-web\\\\n...\"\n})\n\n# Flow: Direct write to viking://agent/skills/{name}/ → SemanticQueue\n```\n\n### Memory Extraction\n\n```python\n# Memory auto-extracted from session\nawait session.commit()\n\n# Flow: MemoryExtractor → TreeBuilder(scope=user) → SemanticQueue\n```\n\n## Related Documents\n\n- [Architecture Overview](./01-architecture.md) - System architecture\n- [Context Layers](./03-context-layers.md) - L0/L1/L2 model\n- [Storage Architecture](./05-storage.md) - AGFS and vector index\n- [Session Management](./08-session.md) - Memory extraction details\n"

    "content": "# Path Locks and Crash Recovery\n\nOpenViking uses two simple primitives — **path locks** and **redo log** — to protect the consistency of core write operations (`rm`, `mv`, `add_resource`, `session.commit`), ensuring that VikingFS, VectorDB, and QueueManager remain consistent even when failures occur.\n\n## Design Philosophy\n\nOpenViking is a context database where FS is the source of truth and VectorDB is a derived index. A lost index can be rebuilt from source data, but lost source data is unrecoverable. Therefore:\n\n> **Better to miss a search result than to return a bad one.**\n\n## Design Principles\n\n1. **Write-exclusive**: Path locks ensure only one write operation can operate on a path at a time\n2. **On by default**: All data operations automatically acquire locks; no extra configuration needed\n3. **Lock as protection**: LockContext acquires locks on entry, releases on exit — no undo/journal/commit semantics\n4. **Only session_memory needs crash recovery**: RedoLog re-executes memory extraction after a process crash\n5. **Queue operations run outside locks**: SemanticQueue/EmbeddingQueue enqueue operations are idempotent and retriable\n\n## Architecture\n\n```\nService Layer (rm / mv / add_resource / session.commit)\n    |\n    v\n+--[LockContext async context manager]--+\n|                                       |\n|  1. Create LockHandle                 |\n|  2. Acquire path lock (poll+timeout)  |\n|  3. Execute operations (FS+VectorDB)  |\n|  4. Release lock                      |\n|                                       |\n|  On exception: auto-release lock,     |\n|  exception propagates unchanged       |\n+---------------------------------------+\n    |\n    v\nStorage Layer (VikingFS, VectorDB, QueueManager)\n```\n\n## Two Core Components\n\n### Component 1: PathLock + LockManager + LockContext (Path Lock System)\n\n**PathLock** implements file-based distributed locks with two lock types — POINT and SUBTREE — using fencing tokens to prevent TOCTOU races and automatic stale lock detection and cleanup.\n\n**LockHandle** is a lightweight lock holder token:\n\n```python\n@dataclass\nclass LockHandle:\n    id: str          # Unique ID used to generate fencing tokens\n    locks: list[str] # Acquired lock file paths\n    created_at: float # Creation time\n```\n\n**LockManager** is a global singleton managing lock lifecycle:\n- Creates/releases LockHandles\n- Background cleanup of leaked locks (in-process safety net)\n- Executes RedoLog recovery on startup\n\n**LockContext** is an async context manager encapsulating the lock/unlock lifecycle:\n\n```python\nfrom openviking.storage.transaction import LockContext, get_lock_manager\n\nasync with LockContext(get_lock_manager(), [path], lock_mode=\"point\") as handle:\n    # Perform operations under lock protection\n    ...\n# Lock automatically released on exit (including exceptions)\n```\n\n### Component 2: RedoLog (Crash Recovery)\n\nUsed only for the memory extraction phase of `session.commit`. Writes a marker before the operation, deletes it after success, and scans for leftover markers on startup to redo.\n\n```\n/local/_system/redo/{task_id}/redo.json\n```\n\nMemory extraction is idempotent — re-extracting from the same archive produces the same result.\n\n## Consistency Issues and Solutions\n\n### rm(uri)\n\n| Problem | Solution |\n|---------|----------|\n| Delete file first, then index -> file gone but index remains -> search returns non-existent file | **Reverse order**: delete index first, then file. Index deletion failure -> both file and index intact |\n\n**Locking strategy** (depends on target type):\n- Deleting a **directory**: `lock_mode=\"subtree\"`, locks the directory itself\n- Deleting a **file**: `lock_mode=\"point\"`, locks the file's parent directory\n\nOperation flow:\n\n```\n1. Check whether target is a directory or file, choose lock mode\n2. Acquire lock\n3. Delete VectorDB index -> immediately invisible to search\n4. Delete FS file\n5. Release lock\n```\n\nVectorDB deletion fails -> exception thrown, lock auto-released, file and index both intact. FS deletion fails -> VectorDB already deleted but file remains, retry is safe.\n\n### mv(old_uri, new_uri)\n\n| Problem | Solution |\n|---------|----------|\n| File moved to new path but index points to old path -> search returns old path (doesn't exist) | Copy first then update index; clean up copy on failure |\n\n**Locking strategy** (handled automatically via `lock_mode=\"mv\"`):\n- Moving a **directory**: SUBTREE lock on both source path and destination parent\n- Moving a **file**: POINT lock on both source's parent and destination parent\n\nOperation flow:\n\n```\n1. Check whether source is a directory or file, set src_is_dir\n2. Acquire mv lock (internally chooses SUBTREE or POINT based on src_is_dir)\n3. Copy to new location (source still intact, safe)\n4. If directory, remove the lock file carried over by cp into the copy\n5. Update VectorDB URIs\n   - Failure -> clean up copy, source and old index intact, consistent state\n6. Delete source\n7. Release lock\n```\n\n### add_resource\n\n| Problem | Solution |\n|---------|----------|\n| File moved from temp to final directory, then crash -> file exists but never searchable | Two separate paths for first-time add vs incremental update |\n| Resource already on disk but rm deletes it while semantic processing / vectorization is still running -> wasted work | Lifecycle SUBTREE lock held from finalization through processing completion |\n\n**First-time add** (target does not exist) — handled in `ResourceProcessor.process_resource` Phase 3.5:\n\n```\n1. Acquire POINT lock on parent of final_uri\n2. agfs.mv temp directory -> final location\n3. Acquire SUBTREE lock on final_uri (inside POINT lock, eliminating race window)\n4. Release POINT lock\n5. Clean up temp directory\n6. Enqueue SemanticMsg(lifecycle_lock_handle_id=...) -> DAG runs on final\n7. DAG starts lock refresh loop (refreshes timestamp every lock_expire/2 seconds)\n8. DAG complete + all embeddings done -> release SUBTREE lock\n```\n\nDuring this period, `rm` attempting to acquire a SUBTREE lock on the same path will fail with `ResourceBusyError`.\n\n**Incremental update** (target already exists) — temp stays in place:\n\n```\n1. Acquire SUBTREE lock on target_uri (protect existing resource)\n2. Enqueue SemanticMsg(uri=temp, target_uri=final, lifecycle_lock_handle_id=...)\n3. DAG runs on temp, lock refresh loop active\n4. DAG completion triggers sync_diff_callback or move_temp_to_target_callback\n5. Callback completes -> release SUBTREE lock\n```\n\nNote: DAG callbacks do NOT wrap operations in an outer lock. Each `VikingFS.rm` and `VikingFS.mv` has its own lock internally. An outer lock would conflict with these inner locks causing deadlock.\n\n**Server restart recovery**: SemanticMsg is persisted in QueueFS. On restart, `SemanticProcessor` detects that the `lifecycle_lock_handle_id` handle is missing from the in-memory LockManager and re-acquires a SUBTREE lock.\n\n### session.commit()\n\n| Problem | Solution |\n|---------|----------|\n| Messages cleared but archive not written -> conversation data lost | Phase 1 without lock (incomplete archive has no side effects) + Phase 2 with RedoLog |\n\nLLM calls have unpredictable latency (5s~60s+) and cannot be inside a lock-holding operation. The design splits into two phases:\n\n```\nPhase 1 — Archive (no lock):\n  1. Generate archive summary (LLM)\n  2. Write archive (history/archive_N/messages.jsonl + summaries)\n  3. Clear messages.jsonl\n  4. Clear in-memory message list\n\nPhase 2 — Memory extraction + write (RedoLog):\n  1. Write redo marker (archive_uri, session_uri, user identity)\n  2. Extract memories from archived messages (LLM)\n  3. Write current message state\n  4. Write relations\n  5. Directly enqueue SemanticQueue\n  6. Delete redo marker\n```\n\n**Crash recovery analysis**:\n\n| Crash point | State | Recovery action |\n|------------|-------|----------------|\n| During Phase 1 archive write | No marker | Incomplete archive; next commit scans history/ for index, unaffected |\n| Phase 1 archive complete but messages not cleared | No marker | Archive complete + messages still present = redundant but safe |\n| During Phase 2 memory extraction/write | Redo marker exists | On startup: redo extraction + write + enqueue from archive |\n| Phase 2 complete | Redo marker deleted | No recovery needed |\n\n## LockContext\n\n`LockContext` is an **async** context manager that encapsulates lock acquisition and release:\n\n```python\nfrom openviking.storage.transaction import LockContext, get_lock_manager\n\nlock_manager = get_lock_manager()\n\n# Point lock (write operations, semantic processing)\nasync with LockContext(lock_manager, [path], lock_mode=\"point\"):\n    # Perform operations...\n    pass\n\n# Subtree lock (delete operations)\nasync with LockContext(lock_manager, [path], lock_mode=\"subtree\"):\n    # Perform operations...\n    pass\n\n# MV lock (move operations)\nasync with LockContext(lock_manager, [src], lock_mode=\"mv\", mv_dst_parent_path=dst):\n    # Perform operations...\n    pass\n```\n\n**Lock modes**:\n\n| lock_mode | Use case | Behavior |\n|-----------|----------|----------|\n| `point` | Write operations, semantic processing | Lock the specified path; conflicts with any lock on the same path and any SUBTREE lock on ancestors |\n| `subtree` | Delete operations | Lock the subtree root; conflicts with any lock on the same path, any lock on descendants, and any SUBTREE lock on ancestors |\n| `mv` | Move operations | Directory move: SUBTREE lock on both source and destination; File move: POINT lock on source parent and destination (controlled by `src_is_dir`) |\n\n**Exception handling**: `__aexit__` always releases locks and does not swallow exceptions. Lock acquisition failure raises `LockAcquisitionError`.\n\n## Lock Types (POINT vs SUBTREE)\n\nThe lock mechanism uses two lock types to handle different conflict patterns:\n\n| | POINT on same path | SUBTREE on same path | POINT on descendant | SUBTREE on ancestor |\n|---|---|---|---|---|\n| **POINT** | Conflict | Conflict | — | Conflict |\n| **SUBTREE** | Conflict | Conflict | Conflict | Conflict |\n\n- **POINT (P)**: Used for write and semantic-processing operations. Only locks a single directory. Blocks if any ancestor holds a SUBTREE lock.\n- **SUBTREE (S)**: Used for rm and mv operations. Logically covers the entire subtree but only writes **one lock file** at the root. Before acquiring, scans all descendants and ancestor directories for conflicting locks.\n\n## Lock Mechanism\n\n### Lock Protocol\n\nLock file path: `{path}/.path.ovlock`\n\nLock file content (Fencing Token):\n```\n{handle_id}:{time_ns}:{lock_type}\n```\n\nWhere `lock_type` is `P` (POINT) or `S` (SUBTREE).\n\n### Lock Acquisition (POINT mode)\n\n```\nloop until timeout (poll interval: 200ms):\n    1. Check target directory exists\n    2. Check if target directory is locked by another operation\n       - Stale lock? -> remove and retry\n       - Active lock? -> wait\n    3. Check all ancestor directories for SUBTREE locks\n       - Stale lock? -> remove and retry\n       - Active lock? -> wait\n    4. Write POINT (P) lock file\n    5. TOCTOU double-check: re-scan ancestors for SUBTREE locks\n       - Conflict found: compare (timestamp, handle_id)\n       - Later one (larger timestamp/handle_id) backs off (removes own lock) to prevent livelock\n       - Wait and retry\n    6. Verify lock file ownership (fencing token matches)\n    7. Success\n\nTimeout (default 0 = no-wait) raises LockAcquisitionError\n```\n\n### Lock Acquisition (SUBTREE mode)\n\n```\nloop until timeout (poll interval: 200ms):\n    1. Check target directory exists\n    2. Check if target directory is locked by another operation\n       - Stale lock? -> remove and retry\n       - Active lock? -> wait\n    3. Check all ancestor directories for SUBTREE locks\n       - Stale lock? -> remove and retry\n       - Active lock? -> wait\n    4. Scan all descendant directories for any locks by other operations\n       - Stale lock? -> remove and retry\n       - Active lock? -> wait\n    5. Write SUBTREE (S) lock file (only one file, at the root path)\n    6. TOCTOU double-check: re-scan descendants and ancestors\n       - Conflict found: compare (timestamp, handle_id)\n       - Later one (larger timestamp/handle_id) backs off (removes own lock) to prevent livelock\n       - Wait and retry\n    7. Verify lock file ownership (fencing token matches)\n    8. Success\n\nTimeout (default 0 = no-wait) raises LockAcquisitionError\n```\n\n### Lock Expiry Cleanup\n\n**Stale lock detection**: PathLock checks the fencing token timestamp. Locks older than `lock_expire` (default 300s) are considered stale and are removed automatically during acquisition.\n\n**In-process cleanup**: LockManager checks active LockHandles every 60 seconds. Handles created more than 3600 seconds ago are force-released.\n\n**Orphan locks**: Lock files left behind after a process crash are automatically removed via stale lock detection when any operation next attempts to acquire a lock on the same path.\n\n## Crash Recovery\n\n`LockManager.start()` automatically scans for leftover markers in `/local/_system/redo/` on startup:\n\n| Scenario | Recovery action |\n|----------|----------------|\n| session_memory extraction crash | Redo memory extraction + write + enqueue from archive |\n| Crash while holding lock | Lock file remains in AGFS; stale detection auto-cleans on next acquisition (default 300s expiry) |\n| Crash after enqueue, before worker processes | QueueFS SQLite persistence; worker auto-pulls after restart |\n| Orphan index | Cleaned on L2 on-demand load |\n\n### Defense Summary\n\n| Failure scenario | Defense | Recovery timing |\n|-----------------|--------|-----------------|\n| Crash during operation | Lock auto-expires + stale detection | Next acquisition of same path lock |\n| Crash during add_resource semantic processing | Lifecycle lock expires + SemanticProcessor re-acquires on restart | Worker restart |\n| Crash during session.commit Phase 2 | RedoLog marker + redo | On restart |\n| Crash after enqueue, before worker | QueueFS SQLite persistence | Worker restart |\n| Orphan index | L2 on-demand load cleanup | When user accesses |\n\n## Configuration\n\nPath locks are enabled by default with no extra configuration needed. **The default behavior is no-wait**: if the path is locked, `LockAcquisitionError` is raised immediately. To allow wait/retry, configure the `storage.transaction` section:\n\n```json\n{\n  \"storage\": {\n    \"transaction\": {\n      \"lock_timeout\": 5.0,\n      \"lock_expire\": 300.0\n    }\n  }\n}\n```\n\n| Parameter | Type | Description | Default |\n|-----------|------|-------------|---------|\n| `lock_timeout` | float | Lock acquisition timeout (seconds). `0` = fail immediately if locked (default). `> 0` = wait/retry up to this many seconds. | `0.0` |\n| `lock_expire` | float | Stale lock expiry threshold (seconds). Locks held longer than this by a crashed process are force-released. | `300.0` |\n\n### QueueFS Persistence\n\nThe lock mechanism relies on QueueFS using the SQLite backend to ensure enqueued tasks survive process restarts. This is the default configuration and requires no manual setup.\n\n## Related Documentation\n\n- [Architecture](./01-architecture.md) - System architecture overview\n- [Storage](./05-storage.md) - AGFS and vector store\n- [Session Management](./08-session.md) - Session and memory management\n- [Configuration](../guides/01-configuration.md) - Configuration reference\n"

    "content": "# FAQ\n\n## Basic Concepts\n\n### What is OpenViking? What problems does it solve?\n\nOpenViking is an open-source context database designed specifically for AI Agents. It solves core pain points when building AI Agents:\n\n- **Fragmented Context**: Memories, resources, and skills are scattered everywhere, difficult to manage uniformly\n- **Poor Retrieval Effectiveness**: Traditional RAG's flat storage lacks global view, making it hard to understand complete context\n- **Unobservable Context**: Implicit retrieval chains are like black boxes, difficult to debug when errors occur\n- **Limited Memory Iteration**: Lacks Agent-related task memory and self-evolution capabilities\n\nOpenViking unifies all context management through a filesystem paradigm, enabling tiered delivery and self-iteration.\n\n### What's the fundamental difference between OpenViking and traditional vector databases?\n\n| Dimension | Traditional Vector DB | OpenViking |\n|-----------|----------------------|------------|\n| **Storage Model** | Flat vector storage | Hierarchical filesystem (AGFS) |\n| **Retrieval Method** | Single vector similarity search | Directory recursive retrieval + Intent analysis + Rerank |\n| **Output Format** | Raw chunks | Structured context (L0 Abstract/L1 Overview/L2 Details) |\n| **Memory Capability** | Not supported | Built-in 6 memory categories with auto-extraction and iteration |\n| **Observability** | Black box | Fully traceable retrieval trajectory |\n| **Context Types** | Documents only | Resource + Memory + Skill three types |\n\n### What is the L0/L1/L2 layered model? Why is it needed?\n\nL0/L1/L2 is OpenViking's progressive content loading mechanism, solving the problem of \"stuffing massive context into prompts all at once\":\n\n| Layer | Name | Token Limit | Purpose |\n|-------|------|-------------|---------|\n| **L0** | Abstract | ~100 tokens | Vector search recall, quick filtering, list display |\n| **L1** | Overview | ~2000 tokens | Rerank refinement, content navigation, decision reference |\n| **L2** | Details | Unlimited | Complete original content, on-demand deep loading |\n\nThis design allows Agents to browse abstracts for quick positioning, then load details on demand, significantly saving token consumption.\n\n### What is Viking URI? What's its purpose?\n\nViking URI is OpenViking's unified resource identifier, formatted as `viking://{scope}/{path}`. It enables precise location of any context:\n\n```\nviking://\n├── resources/              # Knowledge base: documents, code, web pages, etc.\n│   └── my_project/\n├── user/                   # User context\n│   └── memories/           # User memories (preferences, entities, events)\n└── agent/                  # Agent context\n    ├── skills/             # Callable skills\n    └── memories/           # Agent memories (cases, patterns)\n```\n\n## Installation & Configuration\n\n### What are the environment requirements?\n\n- **Python Version**: 3.10 or higher\n- **Build Tools** (if installing from source or on unsupported platforms): Go 1.19+, GCC 9+ or Clang 11+\n- **Required Dependencies**: Embedding model (Volcengine Doubao recommended)\n- **Optional Dependencies**:\n  - VLM (Vision Language Model): For multimodal content processing and semantic extraction\n  - Rerank model: For improved retrieval precision\n\n### What are `binding-client` and `http-client`? Which one should I choose?\n\n- **`binding-client` (Default)**: Runs AGFS logic directly within the Python process via CGO bindings. Advantages: extremely high performance, zero network latency; Disadvantages: requires a compiled AGFS shared library locally.\n- **`http-client`**: Communicates with a standalone `agfs-server` via HTTP. Advantages: decoupled deployment, no local Go compilation needed; Disadvantages: some network communication overhead.\n\nIf your environment supports Go compilation or you've installed a Wheel package containing pre-compiled libraries, the default `binding-client` is recommended.\n\n### What should I do if I encounter \"AGFS binding library not found\"?\n\nThis usually means the AGFS shared library is not pre-built in your environment. You can:\n1. **Re-compile and install**: Run `pip install -e . --force-reinstall` in the project root (requires Go environment).\n2. **Switch to HTTP mode**: Set `storage.agfs.mode = \"http-client\"` in your `ov.conf` and ensure an `agfs-server` is running.\n\n### How do I install/upgrade OpenViking?\n\n```bash\npip install openviking --upgrade --force-reinstall\n\n```\n\n### How do I configure OpenViking?\n\nCreate an `~/.openviking/ov.conf` configuration file in your project directory:\n\n```json\n{\n  \"embedding\": {\n    \"dense\": {\n      \"provider\": \"volcengine\",\n      \"api_key\": \"your-api-key\",\n      \"model\": \"doubao-embedding-vision-250615\",\n      \"dimension\": 1024,\n      \"input\": \"multimodal\"\n    }\n  },\n  \"vlm\": {\n    \"provider\": \"volcengine\",\n    \"api_key\": \"your-api-key\",\n    \"model\": \"doubao-seed-2-0-pro-260215\",\n    \"api_base\": \"https://ark.cn-beijing.volces.com/api/v3\"\n  },\n  \"rerank\": {\n    \"provider\": \"volcengine\",\n    \"api_key\": \"your-api-key\",\n    \"model\": \"doubao-rerank-250615\"\n  },\n  \"storage\": {\n    \"workspace\": \"./data\",\n    \"agfs\": { \"backend\": \"local\" },\n    \"vectordb\": { \"backend\": \"local\" }\n  }\n}\n```\n\nConfig files at the default path `~/.openviking/ov.conf` are loaded automatically; you can also specify a different path via the `OPENVIKING_CONFIG_FILE` environment variable or `--config` flag. See [Configuration Guide](../guides/01-configuration.md) for details.\n\n### What Embedding providers are supported?\n\n| Provider | Description |\n|---------|-------------|\n| `volcengine` | Volcengine Embedding API (Recommended) |\n| `openai` | OpenAI Embedding API |\n| `vikingdb` | VikingDB Embedding API |\n| `jina` | Jina AI Embedding API |\n| `ollama` | Ollama (local OpenAI-compatible server, no API key required) |\n\nSupports Dense, Sparse, and Hybrid embedding modes.\n\n## Usage Guide\n\n### How do I initialize the client?\n\n```python\nimport openviking as ov\n\n# Async client - embedded mode (recommended)\nclient = ov.AsyncOpenViking(path=\"./my_data\")\nawait client.initialize()\n\n# Async client - HTTP client mode\nclient = ov.AsyncHTTPClient(url=\"http://localhost:1933\", api_key=\"your-key\")\nawait client.initialize()\n```\n\nThe SDK constructor only accepts `url`, `api_key`, and `path` parameters. Other configuration (embedding, vlm, etc.) is managed through the `ov.conf` config file.\n\n### What file formats are supported?\n\n| Type | Supported Formats |\n|------|-------------------|\n| **Text** | `.txt`, `.md`, `.json`, `.yaml` |\n| **Code** | `.py`, `.js`, `.ts`, `.go`, `.java`, `.cpp`, etc. |\n| **Documents** | `.pdf`, `.docx` |\n| **Images** | `.png`, `.jpg`, `.jpeg`, `.gif`, `.webp` |\n| **Video** | `.mp4`, `.mov`, `.avi` |\n| **Audio** | `.mp3`, `.wav`, `.m4a` |\n\n### How do I add resources?\n\n```python\n# Add single file\nawait client.add_resource(\n    \"./document.pdf\",\n    reason=\"Project technical documentation\",  # Describe resource purpose to improve retrieval quality\n    target=\"viking://resources/docs/\"  # Specify storage location\n)\n\n# Add web page\nawait client.add_resource(\n    \"https://example.com/api-docs\",\n    reason=\"API reference documentation\"\n)\n\n# Wait for processing to complete\nawait client.wait_processed()\n```\n\n### What's the difference between `find()` and `search()`? Which should I use?\n\n| Feature | `find()` | `search()` |\n|---------|----------|------------|\n| **Session Context** | Not required | Required |\n| **Intent Analysis** | Not used | Uses LLM to analyze and generate 0-5 queries |\n| **Latency** | Low | Higher |\n| **Use Case** | Simple semantic search | Complex tasks requiring context understanding |\n\n```python\n# find(): Simple direct semantic search\nresults = await client.find(\n    \"OAuth authentication flow\",\n    target_uri=\"viking://resources/\"\n)\n\n# search(): Complex tasks requiring intent analysis\nresults = await client.search(\n    \"Help me implement user login functionality\",\n    session_info=session\n)\n```\n\n**Selection Guide**:\n- Know exactly what you're looking for → Use `find()`\n- Complex tasks needing multiple context types → Use `search()`\n\n### How do I use session management?\n\nSession management is a core capability of OpenViking, supporting conversation tracking and memory extraction:\n\n```python\n# Create session\nsession = client.session()\n\n# Add conversation messages\nawait session.add_message(\"user\", [{\"type\": \"text\", \"text\": \"Help me analyze performance issues in this code\"}])\nawait session.add_message(\"assistant\", [{\"type\": \"text\", \"text\": \"Let me analyze...\"}])\n\n# Mark used context (for tracking)\nawait session.used([\"viking://resources/code/main.py\"])\n\n# Commit session to trigger memory extraction\nawait session.commit()\n```\n\n### What memory types does OpenViking support?\n\nOpenViking has 6 built-in memory categories, automatically extracted during session commit:\n\n| Category | Belongs To | Description |\n|----------|------------|-------------|\n| **profile** | user | User basic info (name, role, etc.) |\n| **preferences** | user | User preferences (code style, tool choices, etc.) |\n| **entities** | user | Entity memories (people, projects, organizations, etc.) |\n| **events** | user | Event records (decisions, milestones, etc.) |\n| **cases** | agent | Cases learned by Agent |\n| **patterns** | agent | Patterns learned by Agent |\n\n### How do I use Unix-like filesystem APIs?\n\n```python\n# List directory contents\nitems = await client.ls(\"viking://resources/\")\n\n# Read full content (L2)\ncontent = await client.read(\"viking://resources/doc.md\")\n\n# Get abstract (L0)\nabstract = await client.abstract(\"viking://resources\")\n\n# Get overview (L1)\noverview = await client.overview(\"viking://resources\")\n```\n\n## Retrieval Optimization\n\n### How do I improve retrieval quality?\n\n1. **Use Rerank model**: Configuring Rerank significantly improves ranking effectiveness\n2. **Provide meaningful `reason`**: Describe purpose when adding resources to help system understand resource value\n3. **Organize directory structure properly**: Use `target` parameter to group related resources together\n4. **Use session context**: `search()` leverages session history for intent analysis\n5. **Choose appropriate Embedding mode**: Use `multimodal` input for multimodal content\n\n### How is the retrieval result score calculated?\n\nOpenViking uses a score propagation mechanism:\n\n```\nFinal Score = 0.5 × Embedding Similarity + 0.5 × Parent Directory Score\n```\n\nThis design gives content under high-scoring directories a boost, reflecting the importance of \"contextual environment\".\n\n### What is directory recursive retrieval?\n\nDirectory recursive retrieval is OpenViking's innovative retrieval strategy:\n\n1. **Intent Analysis**: Analyze query to generate multiple retrieval conditions\n2. **Initial Positioning**: Vector retrieval to locate high-scoring directories\n3. **Refined Exploration**: Secondary retrieval within high-scoring directories\n4. **Recursive Drill-down**: Layer-by-layer recursion until convergence\n5. **Result Aggregation**: Return the most relevant context\n\nThis strategy finds semantically matching fragments while understanding the complete context of the information.\n\n## Troubleshooting\n\n### Resources not being indexed after adding\n\n**Possible causes and solutions**:\n\n1. **Didn't wait for processing to complete**\n   ```python\n   await client.add_resource(\"./doc.pdf\")\n   await client.wait_processed()  # Must wait\n   ```\n\n2. **Embedding model configuration error**\n   - Check if `api_key` in `~/.openviking/ov.conf` is correct\n   - Confirm model name and endpoint are configured correctly\n\n3. **Unsupported file format**\n   - Check if file extension is in the supported list\n   - Confirm file content is valid and not corrupted\n\n4. **View processing logs**\n   ```python\n   import logging\n   logging.basicConfig(level=logging.DEBUG)\n   ```\n\n### Search not returning expected results\n\n**Troubleshooting steps**:\n\n1. **Confirm resources have been processed**\n   ```python\n   # Check if resources exist\n   items = await client.ls(\"viking://resources/\")\n   ```\n\n2. **Check `target_uri` filter condition**\n   - Ensure search scope includes target resources\n   - Try expanding search scope\n\n3. **Try different query approaches**\n   - Use more specific or broader keywords\n   - Compare effects of `find()` and `search()`\n\n4. **Check L0 abstract quality**\n   ```python\n   abstract = await client.abstract(\"viking://resources/your-doc\")\n   print(abstract)  # Confirm abstract accurately reflects content\n   ```\n\n### Memory extraction not working\n\n**Troubleshooting steps**:\n\n1. **Ensure `commit()` was called**\n   ```python\n   await session.commit()  # Triggers memory extraction\n   ```\n\n2. **Check VLM configuration**\n   - Memory extraction requires VLM model\n   - Confirm `vlm` configuration is correct\n\n3. **Confirm conversation content is meaningful**\n   - Casual chat may not produce memories\n   - Needs to contain extractable information (preferences, entities, events, etc.)\n\n4. **View extracted memories**\n   ```python\n   memories = await client.find(\"\", target_uri=\"viking://user/memories/\")\n   ```\n\n### Performance issues\n\n**Optimization suggestions**:\n\n1. **Batch processing**: Adding multiple resources at once is more efficient than one by one\n2. **Set appropriate `batch_size`**: Adjust batch processing size in Embedding configuration\n3. **Use local storage**: Use `local` backend during development to reduce network latency\n4. **Async operations**: Fully utilize `AsyncOpenViking` / `AsyncHTTPClient`'s async capabilities\n\n## Deployment\n\n### What's the difference between embedded mode and service mode?\n\n| Mode | Use Case | Characteristics |\n|------|----------|-----------------|\n| **Embedded** | Local development, single-process apps | Auto-starts AGFS subprocess, uses local vector index |\n| **Service Mode** | Production, distributed deployment | Connects to remote services, supports multi-instance concurrency, independently scalable |\n\n```python\n# Embedded mode\nclient = ov.AsyncOpenViking(path=\"./data\")\n\n# HTTP client mode (connects to a remote server)\nclient = ov.AsyncHTTPClient(url=\"http://localhost:1933\", api_key=\"your-key\")\n```\n\n### Is OpenViking open source?\n\nYes, OpenViking is fully open source under the Apache 2.0 license.\n\n## Related Documentation\n\n- [Introduction](../getting-started/01-introduction.md) -

    "content": "# Introduction\n\n**OpenViking** is an open-source context database designed specifically for AI Agents. OpenViking unifies the management of context (memory, resources, and skills) that Agents need through a **file system paradigm**, enabling **hierarchical context delivery** and **self-iteration**. The ultimate goal is to lower the barrier for Agent development, allowing developers to focus on business innovation rather than underlying context management.\n\n## Why OpenViking\n\nIn the AI era, data is abundant, but high-quality context is scarce. When building AI Agents, developers often face these challenges:\n\n- **Context Fragmentation**: Memory in code, resources in vector databases, skills scattered everywhere — difficult to manage uniformly\n- **Context Explosion**: Long-running Agent tasks generate context with each execution; simple truncation or compression leads to information loss\n- **Poor Retrieval Quality**: Traditional RAG uses flat storage, lacking global perspective and struggling to understand complete context\n- **Context Opacity**: Traditional RAG's implicit retrieval pipeline is like a black box, making debugging difficult\n- **Limited Memory Iteration**: Current memory systems only record user memories, lacking Agent-related task memories\n\nOpenViking is designed to solve these pain points.\n\n## Core Features\n\n### 1. File System Management Paradigm\n\nMoving away from traditional flat database thinking, all context is organized as a virtual file system. Agents no longer rely solely on vector search to find data — they can locate and browse data through deterministic paths and standard file system commands.\n\n**Unified URI Identification**: Each context is assigned a unique `viking://` URI, enabling precise location and access to resources stored in different locations.\n\n```\nviking://\n├── resources/              # Resources: project docs, code repos, web pages\n│   └── my_project/\n├── user/                   # User: preferences, habits\n│   └── memories/\n└── agent/                  # Agent: skills, instructions, task memories\n    ├── skills/\n    └── memories/\n```\n\n**Three Context Types**:\n\n| Type | Purpose | Lifecycle |\n|------|---------|-----------|\n| **Resource** | Knowledge and rules (docs, code, FAQ) | Long-term, relatively static |\n| **Memory** | Agent's cognition (user preferences, learned experiences) | Long-term, dynamically updated |\n| **Skill** | Callable capabilities (tools, MCP) | Long-term, static |\n\n**Unix-like API**: Familiar command-style operations\n\n```python\nclient.find(\"user authentication\")       # Semantic search\nclient.ls(\"viking://resources/\")         # List directory\nclient.read(\"viking://resources/doc\")    # Read content\nclient.abstract(\"viking://...\")          # Get L0 abstract\nclient.overview(\"viking://...\")          # Get L1 overview\n```\n\n### 2. Hierarchical Context On-Demand Loading\n\nStuffing massive context into prompts all at once is not only expensive but also risks exceeding model windows and introducing noise. OpenViking automatically processes context into three levels upon ingestion:\n\n| Level | Name | Token Limit | Purpose |\n|-------|------|-------------|---------|\n| **L0** | Abstract | ~100 tokens | Vector search, quick filtering |\n| **L1** | Overview | ~2k tokens | Rerank, content navigation |\n| **L2** | Detail | Unlimited | Full content, on-demand loading |\n\n```\nviking://resources/my_project/\n├── .abstract.md               # L0 layer: abstract\n├── .overview.md               # L1 layer: overview\n├── docs/\n│   ├── .abstract.md          # Each directory has L0/L1 layers\n│   ├── .overview.md\n│   └── api.md                # L2 layer: full content\n└── src/\n```\n\n### 3. Directory Recursive Retrieval\n\nSingle vector retrieval struggles with complex query intents. OpenViking implements an innovative **directory recursive retrieval strategy**:\n\n1. **Intent Analysis**: Generate multiple retrieval conditions through intent analysis\n2. **Initial Positioning**: Use vector retrieval to quickly locate high-scoring directories\n3. **Fine Exploration**: Perform secondary retrieval within directories, updating candidate sets with high-scoring results\n4. **Recursive Descent**: If subdirectories exist, recursively repeat the secondary retrieval\n5. **Result Aggregation**: Return the most relevant context\n\nThis \"lock onto high-scoring directories first, then explore content in detail\" strategy not only finds semantically matching fragments but also understands the complete context of information.\n\n### 4. Visualized Retrieval Traces\n\nOpenViking's organization uses a hierarchical virtual file system structure, with all context integrated in a unified format and each entry corresponding to a unique URI, breaking away from traditional flat black-box management.\n\nThe retrieval process uses directory recursive strategy, with complete traces of directory browsing and file positioning preserved for each retrieval, enabling clear observation of problem sources and guiding retrieval logic optimization.\n\n### 5. Automatic Session Management\n\nOpenViking has built-in memory self-iteration loops. At the end of each session, developers can trigger memory extraction, and the system asynchronously analyzes task execution results and user feedback, automatically updating User and Agent memory directories.\n\n**6 Memory Categories**:\n\n| Category | Owner | Description |\n|----------|-------|-------------|\n| **profile** | user | User basic information |\n| **preferences** | user | User preferences by topic |\n| **entities** | user | Entity memories (people, projects) |\n| **events** | user | Event records (decisions, milestones) |\n| **cases** | agent | Learned cases |\n| **patterns** | agent | Learned patterns |\n\nEnabling Agents to become \"smarter with use\" through world interaction, achieving self-evolution.\n\n## Next Steps\n\n- [Quick Start](./02-quickstart.md) - Get started in 5 minutes\n- [Architecture Overview](../concepts/01-architecture.md) - Understand system design\n- [Context Types](../concepts/02-context-types.md) - Deep dive into three context types\n- [Retrieval Mechanism](../concepts/07-retrieval.md) - Learn about retrieval flow\n"

    "content": "# Quick Start\n\nGet started with OpenViking in 5 minutes.\n\n## Prerequisites\n\nBefore using OpenViking, ensure your environment meets the following requirements:\n\n- **Python Version**: 3.10 or higher\n- **Operating System**: Linux, macOS, Windows\n- **Network Connection**: Stable network connection required (for downloading dependencies and accessing model services)\n\n## Installation & Startup\n\nOpenViking can be installed via a Python Package to be used as a local library, or you can quickly launch it as an independent service using Docker.\n\n### Option 1: Install via pip (As a local library)\n\n```bash\npip install openviking --upgrade --force-reinstall\n```\n\n### Option 2: Start via Docker (As an independent service)\n\nIf you prefer to run OpenViking as a standalone service, Docker is recommended.\n\n1. **Prepare Configuration and Data Directories**\n   Create a data directory on your host machine and prepare the `ov.conf` configuration file (see the \"Configuration\" section below for details):\n   ```bash\n   mkdir -p ~/.openviking/data\n   touch ~/.openviking/ov.conf\n   ```\n\n2. **Start with Docker Compose**\n   Create a `docker-compose.yml` file:\n   ```yaml\n   services:\n     openviking:\n       image: ghcr.io/volcengine/openviking:main\n       container_name: openviking\n       ports:\n         - \"1933:1933\"\n       volumes:\n         - ~/.openviking/ov.conf:/app/ov.conf\n         - ~/.openviking/data:/app/data\n       restart: unless-stopped\n   ```\n   Then run the following command in the same directory:\n   ```bash\n   docker-compose up -d\n   ```\n\n> **💡 Mac Local Network Access Tip (Connection reset error):**\n>\n> By default, OpenViking only listens to `127.0.0.1` for security reasons. If you are using Docker on a Mac, your host machine may not be able to access it directly via `localhost:1933`.\n> \n> **Recommended Solution: Use socat for port forwarding (No config changes needed):**\n> Override the default startup command in your `docker-compose.yml` to use `socat` for internal port forwarding:\n> ```yaml\n> services:\n>   openviking:\n>     image: ghcr.io/volcengine/openviking:main\n>     ports:\n>       - \"1933:1934\" # Map host 1933 to container 1934\n>     volumes:\n>       - ~/.openviking/ov.conf:/app/ov.conf\n>       - ~/.openviking/data:/app/data\n>     command: /bin/sh -c \"apt-get update && apt-get install -y socat && socat TCP-LISTEN:1934,fork,reuseaddr TCP:127.0.0.1:1933 & openviking-server\"\n> ```\n> This perfectly solves the access issue for Mac host machines.\n\n## Model Preparation\n\nOpenViking requires the following model capabilities:\n- **VLM Model**: For image and content understanding\n- **Embedding Model**: For vectorization and semantic retrieval\n\nOpenViking supports multiple model services:\n- **Volcengine (Doubao Models)**: Recommended, cost-effective with good performance, free quota for new users. For purchase and activation, see: [Volcengine Purchase Guide](../guides/02-volcengine-purchase-guide.md)\n- **OpenAI Models**: Supports GPT-4V and other VLM models, plus OpenAI Embedding models\n- **Other Custom Model Services**: Supports model services compatible with OpenAI API format\n\n## Configuration\n\n### Configuration File Template\n\nCreate a configuration file `~/.openviking/ov.conf`:\n\n```json\n{\n  \"embedding\": {\n    \"dense\": {\n      \"api_base\" : \"<api-endpoint>\",\n      \"api_key\"  : \"<your-api-key>\",\n      \"provider\" : \"<provider-type>\",\n      \"dimension\": 1024,\n      \"model\"    : \"<model-name>\"\n    }\n  },\n  \"vlm\": {\n    \"api_base\" : \"<api-endpoint>\",\n    \"api_key\"  : \"<your-api-key>\",\n    \"provider\" : \"<provider-type>\",\n    \"model\"    : \"<model-name>\"\n  }\n}\n```\n\nFor complete examples for each model provider, see [Configuration Guide - Examples](../guides/01-configuration.md#configuration-examples).\n\n### Environment Variables\n\nWhen the config file is at the default path `~/.openviking/ov.conf`, no additional setup is needed — OpenViking loads it automatically.\n\nIf the config file is at a different location, specify it via environment variable:\n\n```bash\nexport OPENVIKING_CONFIG_FILE=/path/to/your/ov.conf\n```\n\n## Run Your First Example\n\n### Create Python Script\n\nCreate `example.py`:\n\n```python\nimport openviking as ov\n\n# Initialize OpenViking client with data directory\nclient = ov.OpenViking(path=\"./data\")\n\ntry:\n    # Initialize the client\n    client.initialize()\n\n    # Add resource (supports URL, file, or directory)\n    add_result = client.add_resource(\n        path=\"https://raw.githubusercontent.com/volcengine/OpenViking/refs/heads/main/README.md\"\n    )\n    root_uri = add_result['root_uri']\n\n    # Explore the resource tree structure\n    ls_result = client.ls(root_uri)\n    print(f\"Directory structure:\\n{ls_result}\\n\")\n\n    # Use glob to find markdown files\n    glob_result = client.glob(pattern=\"**/*.md\", uri=root_uri)\n    if glob_result['matches']:\n        content = client.read(glob_result['matches'][0])\n        print(f\"Content preview: {content[:200]}...\\n\")\n\n    # Wait for semantic processing to complete\n    print(\"Wait for semantic processing...\")\n    client.wait_processed()\n\n    # Get abstract and overview of the resource\n    abstract = client.abstract(root_uri)\n    overview = client.overview(root_uri)\n    print(f\"Abstract:\\n{abstract}\\n\\nOverview:\\n{overview}\\n\")\n\n    # Perform semantic search\n    results = client.find(\"what is openviking\", target_uri=root_uri)\n    print(\"Search results:\")\n    for r in results.resources:\n        print(f\"  {r.uri} (score: {r.score:.4f})\")\n\n    # Close the client\n    client.close()\n\nexcept Exception as e:\n    print(f\"Error: {e}\")\n```\n\n### Run the Script\n\n```bash\npython example.py\n```\n\n### Expected Output\n\n```\nDirectory structure:\n...\n\nContent preview: ...\n\nWait for semantic processing...\nAbstract:\n...\n\nOverview:\n...\n\nSearch results:\n  viking://resources/... (score: 0.8523)\n  ...\n```\n\nCongratulations! You have successfully run OpenViking.\n\n## Server Mode\n\nWant to run OpenViking as a shared service?

    "content": "# Quick Start: Server Mode\n\nRun OpenViking as a standalone HTTP server and connect from any client.\n\n## Prerequisites\n\n- OpenViking installed (`pip install openviking --upgrade --force-reinstall`)\n- Model configuration ready (see [Quick Start](02-quickstart.md) for setup)\n\n## Start the Server\n\nMake sure you have a config file at `~/.openviking/ov.conf` with your model and storage settings (see [Configuration](../guides/01-configuration.md)).\n\n```bash\n# Config file at default path ~/.openviking/ov.conf — just start\nopenviking-server\n\n# Config file at a different location — specify with --config\nopenviking-server --config /path/to/ov.conf\n\n# Override host/port\nopenviking-server --port 8000\n```\n\nYou should see:\n\n```\nINFO:     Uvicorn running on http://0.0.0.0:1933\n```\n\n## Verify\n\n```bash\ncurl http://localhost:1933/health\n# {\"status\": \"ok\"}\n```\n\n## Connect with Python SDK\n\n```python\nimport openviking as ov\n\nclient = ov.SyncHTTPClient(url=\"http://localhost:1933\")\n```\n\nIf the server has authentication enabled, pass the API key and optionally an agent ID:\n\n```python\nimport openviking as ov\n\nclient = ov.SyncHTTPClient(url=\"http://localhost:1933\", api_key=\"your-key\", agent_id=\"my-agent\")\n```\n\n**Full example:**\n\n```python\nimport openviking as ov\n\nclient = ov.SyncHTTPClient(url=\"http://localhost:1933\")\n\ntry:\n    client.initialize()\n\n    # Add a resource\n    result = client.add_resource(\n        \"https://raw.githubusercontent.com/volcengine/OpenViking/refs/heads/main/README.md\"\n    )\n    root_uri = result[\"root_uri\"]\n\n    # Wait for processing\n    client.wait_processed()\n\n    # Search\n    results = client.find(\"what is openviking\", target_uri=root_uri)\n    for r in results.resources:\n        print(f\"  {r.uri} (score: {r.score:.4f})\")\n\nfinally:\n    client.close()\n```\n\n## Connect with CLI\n\nCreate a CLI config file `~/.openviking/ovcli.conf` that points to your server:\n\n```json\n{\n  \"url\": \"http://localhost:1933\",\n  \"api_key\": \"your-key\"\n}\n```\n\nOnce configured, use the CLI to manage resources and query your Agent's memory:\n\n```bash\n# Check system health\nopenviking observer system\n\n# Add a resource to memory\nopenviking add-resource https://raw.githubusercontent.com/volcengine/OpenViking/refs/heads/main/README.md\n\n# List all synchronized resources\nopenviking ls viking://resources\n\n# Query\nopenviking find \"what is openviking\"\n\n```\n\nIf the config file is at a different location, specify it via environment variable:\n\n```bash\nexport OPENVIKING_CLI_CONFIG_FILE=/path/to/ovcli.conf\n```\n\n## Connect with curl\n\n```bash\n# Add a resource\ncurl -X POST http://localhost:1933/api/v1/resources \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"path\": \"https://raw.githubusercontent.com/volcengine/OpenViking/refs/heads/main/README.md\"}'\n\n# List resources\ncurl \"http://localhost:1933/api/v1/fs/ls?uri=viking://resources/\"\n\n# Semantic search\ncurl -X POST http://localhost:1933/api/v1/search/find \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"query\": \"what is openviking\"}'\n```\n\n## Recommended Cloud Deployment: Volcengine ECS\n\nTo achieve high-performance and scalable Context Memory—providing your Agents with a robust \"long-term memory\"—we recommend deploying on **Volcengine Elastic Compute Service (ECS)** using the **veLinux** operating system.\n\n### 1. Instance Provisioning & Configuration\n\nWhen creating an instance in the [Volcengine ECS Console](https://www.google.com/search?q=https://console.volcengine.com/ecs/region:ecs%2Bcn-beijing/dashboard%3F), we recommend the following specifications:\n\n| Item | Recommended Setting | Notes |\n| --- | --- | --- |\n| **Image** | **veLinux 2.0 (CentOS Compatible)** | Check \"Security Hardening\" |\n| **Instance Type** | **Compute Optimized c3a** (2 vCPU, 4GiB+) | Meets basic inference and retrieval needs |\n| **Storage** | **Add 256 GiB Data Disk** | For vector data persistence |\n| **Networking** | Configure as needed | Open only required business ports (e.g., TCP 1933) |\n\n### 2. Environment Preparation (Mounting the Data Disk)\n\nOnce the instance is running, you must mount the data disk to the `/data` directory. Execute the following commands to automate formatting and mounting:\n\n```bash\n# 1. Create mount point\nmkdir -p /data\n\n# 2. Configure auto-mount (using UUID to prevent drive letter drifting)\ncp /etc/fstab /etc/fstab.bak\nDISK_UUID=$(blkid -s UUID -o value /dev/vdb)\n\nif [ -z \"$DISK_UUID\" ]; then\n    echo \"ERROR: /dev/vdb UUID not found\"\nelse\n    # Append to fstab\n    echo \"UUID=${DISK_UUID} /data ext4 defaults,nofail 0 0\" >> /etc/fstab\n    # Verify and mount\n    mount -a\n    echo \"Mount successful. Current disk status:\"\n    df -Th /data\nfi\n\n```\n\n### 3. Installing Dependencies and OpenViking\n\n```bash\nyum install -y curl git tree\n\n# Step 1: Install uv\ncurl -LsSf https://astral.sh/uv/install.sh | sh\n\n# Step 2: Configure environment variables\necho 'source $HOME/.cargo/env' >> ~/.bashrc\nsource ~/.bashrc\n\n# Verify installation\nuv --version\n\n# Step 3: Create a virtual environment on the data disk\ncd /data\nuv venv ovenv --python 3.11\n\n# Step 4: Activate the virtual environment\nsource /data/ovenv/bin/activate\n\n# Step 5: Verification\necho \"Ready\"\necho \"Python path: $(which python)\"\necho \"Python version: $(python --version)\"\n\n```\n\n* **Install OpenViking**: Install the tool within your activated virtual environment:\n\n```bash\nuv tool install openviking --upgrade\n\n```\n\n### 4. OpenViking Server Configuration and Startup\n\nConfigure your AI models and set up the service to run as a background daemon.\n\n#### Prepare Configuration Files\n\nCreate the directory and configuration file before starting the service.\n\n**Create config directory:**\n\n```bash\nmkdir -p ~/.openviking\n\n```\n\n**Create and edit the config file:**\n\n```bash\nvim ~/.openviking/ov.conf\n\n```\n\n**Configuration Template:**\n\n```json\n{\n  \"embedding\": {\n    \"dense\": {\n      \"api_base\" : \"<api-endpoint>\",   // e.g., https://ark.cn-beijing.volces.com/api/v3\n      \"api_key\"  : \"<your-api-key>\",   // Model service API Key\n      \"provider\" : \"<provider-type>\",  // volcengine or openai\n      \"dimension\": 1024,               // Vector dimension\n      \"model\"    : \"<model-name>\",     // e.g., doubao-embedding-vision-250615\n      \"input\"    : \"multimodal\"        // Use \"multimodal\" for doubao-embedding-vision models\n    }\n  },\n  \"vlm\": {\n    \"api_base\"   : \"<api-endpoint>\",   \n    \"api_key\"    : \"<your-api-key>\",   \n    \"provider\"   : \"<provider-type>\",  \n    \"max_retries\": 2,\n    \"model\"      : \"<model-name>\"      // e.g., doubao-seed-2-0-pro-260215 or gpt-4-vision-preview\n  }\n}\n\n```\n\n> **Tip:** Press `i` to enter Insert mode, paste your config, then press `Esc` and type `:wq` to save and exit.\n\n#### Start the Service in the Background\n\nWe will run the server as a background process using the virtual environment.\n\n* **Activate environment & create logs:**\n\n```bash\nsource /data/ovenv/bin/activate\nmkdir -p /data/log/\n\n```\n\n* **Launch with nohup:**\n\n```bash\nnohup openviking-server > /data/log/openviking.log 2>&1 &\n\n# Note: Data will be stored in ./data relative to the execution path.\n# To stop the service: pkill openviking; pkill agfs\n\n```\n\n*Note: For production environments requiring auto-restart on failure, we recommend using `systemctl` (not covered here).*\n\n#### Verify Service Status\n\n* **Check Process:**\n```bash\nps aux | grep openviking-server\n```\n\n* **Check Logs:**\n```bash\ntail -f /data/log/openviking.log # TODO: Implement log rotation\n```\n\n### 5. Client Configuration and Testing (CLI)\n\nEnsure `openviking` is also installed locally to use the CLI. You must point the `ovcli.conf` to your server address.\n\n* **Prepare client config:**\n\n```bash\nvim ~/.openviking/ovcli.conf\n```\n\n* **Add the following (replace with your server's IP):**\n\n```json\n{\n  \"url\": \"http://XXX.XXX.XXX.XXX:1933\",\n  \"api_key\": \"your-key\"\n}\n\n```\n\n* **Monitor System Health:**\n\n```bash\nopenviking observer system\n```\n\n* **Functional Testing (Upload & Search):**\n\n```bash\n# Upload a test resource\nopenviking add-resource https://raw.githubusercontent.com/ZaynJarvis/doc-eval/refs/heads/main/text.md\n\n# List resources\nopenviking ls viking://resources\n\n# Test retrieval\nopenviking find \"who is Alice\"\n```\n\n## Next Steps\n\n- [Server Deployment](../guides/03-deployment.md) - Configuration, authentication, and deployment options\n- [API Overview](../api/01-overview.md) - Complete API reference\n- [Authentication](../guides/04-authentication.md) - Secure your server with API keys\n"

When using providers that force SSE format, you must set this option to `true`.\n\n### code\n\nControls how code files are summarized via `code_summary_mode`. Both config formats are equivalent:\n\n```json\n{\n  \"code\": {\n    \"code_summary_mode\": \"ast\"\n  }\n}\n```\n\n```json\n{\n  \"parsers\": {\n    \"code\": {\n      \"code_summary_mode\": \"ast\"\n    }\n  }\n}\n```\n\nSet `code_summary_mode` to one of:\n\n| Value | Description | Default |\n|-------|-------------|---------|\n| `\"ast\"` | Extract AST skeleton (class names, method signatures, first-line docstrings, imports) for files ≥100 lines, skip LLM calls. **Recommended for large-scale code indexing** | ✓ |\n| `\"llm\"` | Always use LLM for summarization (higher cost) | |\n| `\"ast_llm\"` | Extract AST skeleton (with full docstrings) first, then pass it as context to LLM (highest quality, moderate cost) | |\n\nAST extraction supports: Python, JavaScript/TypeScript, Rust, Go, Java, C/C++. Other languages, extraction failures, or empty skeletons automatically fall back to LLM.\n\nSee [Code Skeleton Extraction](../concepts/06-extraction.md#code-skeleton-extraction-ast-mode) for details.\n\n### rerank\n\nReranking model for search result refinement.\n\n```json\n{\n  \"rerank\": {\n    \"provider\": \"volcengine\",\n    \"api_key\": \"your-api-key\",\n    \"model\": \"doubao-rerank-250615\"\n  }\n}\n```\n\n**OpenAI-compatible provider (e.g. DashScope qwen3-rerank):**\n\n```json\n{\n  \"rerank\": {\n    \"provider\": \"openai\",\n    \"api_key\": \"your-api-key\",\n    \"api_base\": \"https://dashscope.aliyuncs.com/compatible-api/v1/reranks\",\n    \"model\": \"qwen3-rerank\",\n    \"threshold\": 0.1\n  }\n}\n```\n\n| Parameter | Type | Description |\n|-----------|------|-------------|\n| `provider` | str | `\"volcengine\"` or `\"openai\"` |\n| `api_key` | str | API key |\n| `model` | str | Model name |\n| `api_base` | str | Endpoint URL (openai provider only) |\n| `threshold` | float | Score threshold; results below this are filtered out.

SDK embedded mode and server share this file.\n\n### ovcli.conf\n\nConfig file for the HTTP client (`SyncHTTPClient` / `AsyncHTTPClient`) and CLI to connect to a remote server:\n\n```json\n{\n  \"url\": \"http://localhost:1933\",\n  \"api_key\": \"your-secret-key\",\n  \"agent_id\": \"my-agent\",\n  \"output\": \"table\"\n}\n```\n\n| Field | Description | Default |\n|-------|-------------|---------|\n| `url` | Server address | (required) |\n| `api_key` | API key for authentication (root key or user key) | `null` (no auth) |\n| `agent_id` | Agent identifier for agent space isolation | `null` |\n| `output` | Default output format: `\"table\"` or `\"json\"` | `\"table\"` |\n\nSee [Deployment](./03-deployment.md) for details.\n\n## server Section\n\nWhen running OpenViking as an HTTP service, add a `server` section to `ov.conf`:\n\n```json\n{\n  \"server\": {\n    \"host\": \"0.0.0.0\",\n    \"port\": 1933,\n    \"root_api_key\": \"your-secret-root-key\",\n    \"cors_origins\": [\"*\"]\n  }\n}\n```\n\n| Field | Type | Description | Default |\n|-------|------|-------------|---------|\n| `host` | str | Bind address | `0.0.0.0` |\n| `port` | int | Bind port | `1933` |\n| `root_api_key` | str | Root API key for multi-tenant auth, disabled if not set | `null` |\n| `cors_origins` | list | Allowed CORS origins | `[\"*\"]` |\n\nWhen `root_api_key` is configured, the server enables multi-tenant authentication. Use the Admin API to create accounts and user keys. When not set, the server runs in dev mode with no authentication.\n\nFor startup and deployment details see [Deployment](./03-deployment.md), for authentication see [Authentication](./04-authentication.md).\n\n## storage.transaction Section\n\nPath locks are enabled by default and usually require no configuration. **The default behavior is no-wait**: if the target path is already locked by another operation, the operation fails immediately with `LockAcquisitionError`. Set `lock_timeout` to a positive value to allow polling/retry.\n\n```json\n{\n  \"storage\": {\n    \"transaction\": {\n      \"lock_timeout\": 5.0,\n      \"lock_expire\": 300.0\n    }\n  }\n}\n```\n\n| Parameter | Type | Description | Default |\n|-----------|------|-------------|---------|\n| `lock_timeout` | float | Path lock acquisition timeout (seconds). `0` = fail immediately if locked (default). `> 0` = wait/retry up to this many seconds, then raise `LockAcquisitionError`. | `0.0` |\n| `lock_expire` | float | Stale lock expiry threshold (seconds).

    "content": "# Server Deployment\n\nOpenViking can run as a standalone HTTP server, allowing multiple clients to connect over the network.\n\n## Quick Start\n\n```bash\n# Start server (reads ~/.openviking/ov.conf by default)\nopenviking-server\n\n# Or specify a custom config path\nopenviking-server --config /path/to/ov.conf\n\n# Verify it's running\ncurl http://localhost:1933/health\n# {\"status\": \"ok\"}\n```\n\n## Command Line Options\n\n| Option | Description | Default |\n|--------|-------------|---------|\n| `--config` | Path to ov.conf file | `~/.openviking/ov.conf` |\n| `--host` | Host to bind to | `0.0.0.0` |\n| `--port` | Port to bind to | `1933` |\n\n**Examples**\n\n```bash\n# With default config\nopenviking-server\n\n# With custom port\nopenviking-server --port 8000\n\n# With custom config, host, and port\nopenviking-server --config /path/to/ov.conf --host 127.0.0.1 --port 8000\n```\n\n## Configuration\n\nThe server reads all configuration from `ov.conf`. See [Configuration Guide](./01-configuration.md) for full details on config file format.\n\nThe `server` section in `ov.conf` controls server behavior:\n\n```json\n{\n  \"server\": {\n    \"host\": \"0.0.0.0\",\n    \"port\": 1933,\n    \"root_api_key\": \"your-secret-root-key\",\n    \"cors_origins\": [\"*\"]\n  },\n  \"storage\": {\n    \"workspace\": \"./data\",\n    \"agfs\": { \"backend\": \"local\" },\n    \"vectordb\": { \"backend\": \"local\" }\n  }\n}\n```\n\n## Deployment Modes\n\n### Standalone (Embedded Storage)\n\nServer manages local AGFS and VectorDB. Configure the storage path in `ov.conf`:\n\n```json\n{\n  \"storage\": {\n    \"workspace\": \"./data\",\n    \"agfs\": { \"backend\": \"local\" },\n    \"vectordb\": { \"backend\": \"local\" }\n  }\n}\n```\n\n```bash\nopenviking-server\n```\n\n### Hybrid (Remote Storage)\n\nServer connects to remote AGFS and VectorDB services. Configure remote URLs in `ov.conf`:\n\n```json\n{\n  \"storage\": {\n    \"agfs\": { \"backend\": \"remote\", \"url\": \"http://agfs:1833\" },\n    \"vectordb\": { \"backend\": \"remote\", \"url\": \"http://vectordb:8000\" }\n  }\n}\n```\n\n```bash\nopenviking-server\n```\n\n## Deploying with Systemd (Recommended)\n\nFor Linux systems, you can use Systemd to manage OpenViking as a service, enabling automatic restart and startup on boot. Firstly, you should tried to install and configure openviking on your own.\n\n### Create Systemd Service File\n\nCreate `/etc/systemd/system/openviking.service` file:\n\n```ini\n[Unit]\nDescription=OpenViking HTTP Server\nAfter=network.target\n\n[Service]\nType=simple\n# Replace with your working directory\nWorkingDirectory=/var/lib/openviking\n# Choose one of the following start methods\nExecStart=/usr/bin/openviking-server\nRestart=always\nRestartSec=5\n# Path to config file\nEnvironment=\"OPENVIKING_CONFIG_FILE=/etc/openviking/ov.conf\"\n\n[Install]\nWantedBy=multi-user.target\n```\n\n### Manage the Service\n\nAfter creating the service file, use the following commands to manage the OpenViking service:\n\n```bash\n# Reload systemd configuration\nsudo systemctl daemon-reload\n\n# Start the service\nsudo systemctl start openviking.service\n\n# Enable service on boot\nsudo systemctl enable openviking.service\n\n# Check service status\nsudo systemctl status openviking.service\n\n# View service logs\nsudo journalctl -u openviking.service -f\n```\n\n## Connecting Clients\n\n### Python SDK\n\n```python\nimport openviking as ov\n\nclient = ov.SyncHTTPClient(url=\"http://localhost:1933\", api_key=\"your-key\", agent_id=\"my-agent\")\nclient.initialize()\n\nresults = client.find(\"how to use openviking\")\nclient.close()\n```\n\n### CLI\n\nThe CLI reads connection settings from `ovcli.conf`. Create `~/.openviking/ovcli.conf`:\n\n```json\n{\n  \"url\": \"http://localhost:1933\",\n  \"api_key\": \"your-key\"\n}\n```\n\nOr set the config path via environment variable:\n\n```bash\nexport OPENVIKING_CLI_CONFIG_FILE=/path/to/ovcli.conf\n```\n\nThen use the CLI:\n\n```bash\npython -m openviking ls viking://resources/\n```\n\n### curl\n\n```bash\ncurl http://localhost:1933/api/v1/fs/ls?uri=viking:// \\\n  -H \"X-API-Key: your-key\"\n```\n\n## Cloud Deployment\n\n### Docker\n\nOpenViking provides pre-built Docker images published to GitHub Container Registry:\n\n```bash\ndocker run -d \\\n  --name openviking \\\n  -p 1933:1933 \\\n  -v ~/.openviking/ov.conf:/app/ov.conf \\\n  -v /var/lib/openviking/data:/app/data \\\n  --restart unless-stopped \\\n  ghcr.io/volcengine/openviking:main\n```\n\nYou can also use Docker Compose with the `docker-compose.yml` provided in the project root:\n\n```bash\ndocker compose up -d\n```\n\nTo build the image yourself: `docker build -t openviking:latest .`\n\n### Kubernetes + Helm\n\nThe project provides a Helm chart located at `examples/k8s-helm/`:\n\n```bash\nhelm install openviking ./examples/k8s-helm \\\n  --set openviking.config.embedding.dense.api_key=\"YOUR_API_KEY\" \\\n  --set openviking.config.vlm.api_key=\"YOUR_API_KEY\"\n```\n\nFor a detailed cloud deployment guide (including Volcengine TOS + VikingDB + Ark configuration), see the [Cloud Deployment Guide](../../../examples/cloud/GUIDE.md).\n\n## Health Checks\n\n| Endpoint | Auth | Purpose |\n|----------|------|---------|\n| `GET /health` | No | Liveness probe — returns `{\"status\": \"ok\"}` immediately |\n| `GET /ready` | No | Readiness probe — checks AGFS, VectorDB, APIKeyManager |\n\n```bash\n# Liveness\ncurl http://localhost:1933/health\n\n# Readiness\ncurl http://localhost:1933/ready\n# {\"status\": \"ready\", \"checks\": {\"agfs\": \"ok\", \"vectordb\": \"ok\", \"api_key_manager\": \"ok\"}}\n```\n\nUse `/health` for Kubernetes liveness probes and `/ready` for readiness probes.\n\n## Related Documentation\n\n- [Authentication](04-authentication.md) - API key setup\n- [Monitoring](05-monitoring.md) - Health checks and observability\n- [API Overview](../api/01-overview.md) - Complete API reference\n"

  {
    "path": "docs/en/guides/04-authentication.md",
    "content": "# Authentication\n\nOpenViking Server supports multi-tenant API key authentication with role-based access control.\n\n## Overview\n\nOpenViking uses a two-layer API key system:\n\n| Key Type | Created By | Role | Purpose |\n|----------|-----------|------|---------|\n| Root Key | Server config (`root_api_key`) | ROOT | Full access + admin operations |\n| User Key | Admin API | ADMIN or USER | Per-account access |\n\nAll API keys are plain random tokens with no embedded identity. The server resolves identity by first comparing against the root key, then looking up the user key index.\n\n## Setting Up (Server Side)\n\nConfigure the root API key in the `server` section of `ov.conf`:\n\n```json\n{\n  \"server\": {\n    \"root_api_key\": \"your-secret-root-key\"\n  }\n}\n```\n\nStart the server:\n\n```bash\nopenviking-server\n```\n\n## Managing Accounts and Users\n\nUse the root key to create accounts (workspaces) and users via the Admin API:\n\n```bash\n# Create account with first admin\ncurl -X POST http://localhost:1933/api/v1/admin/accounts \\\n  -H \"X-API-Key: your-secret-root-key\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"account_id\": \"acme\", \"admin_user_id\": \"alice\"}'\n# Returns: {\"result\": {\"account_id\": \"acme\", \"admin_user_id\": \"alice\", \"user_key\": \"...\"}}\n\n# Register a regular user (as ROOT or ADMIN)\ncurl -X POST http://localhost:1933/api/v1/admin/accounts/acme/users \\\n  -H \"X-API-Key: your-secret-root-key\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"user_id\": \"bob\", \"role\": \"user\"}'\n# Returns: {\"result\": {\"account_id\": \"acme\", \"user_id\": \"bob\", \"user_key\": \"...\"}}\n```\n\n## Using API Keys (Client Side)\n\nOpenViking accepts API keys via two headers:\n\n**X-API-Key header**\n\n```bash\ncurl http://localhost:1933/api/v1/fs/ls?uri=viking:// \\\n  -H \"X-API-Key: <user-key>\"\n```\n\n**Authorization: Bearer header**\n\n```bash\ncurl http://localhost:1933/api/v1/fs/ls?uri=viking:// \\\n  -H \"Authorization: Bearer <user-key>\"\n```\n\n**Python SDK (HTTP)**\n\n```python\nimport openviking as ov\n\nclient = ov.SyncHTTPClient(\n    url=\"http://localhost:1933\",\n    api_key=\"<user-key>\",\n    agent_id=\"my-agent\"\n)\n```\n\n**CLI (via ovcli.conf)**\n\n```json\n{\n  \"url\": \"http://localhost:1933\",\n  \"api_key\": \"<user-key>\",\n  \"agent_id\": \"my-agent\"\n}\n```\n\n### Accessing Tenant Data with Root Key\n\nWhen using the root key to access tenant-scoped data APIs (e.g. `ls`, `find`, `sessions`), you must specify the target account and user. The server will reject the request otherwise. Admin API and system status endpoints are not affected.\n\n**curl**\n\n```bash\ncurl http://localhost:1933/api/v1/fs/ls?uri=viking:// \\\n  -H \"X-API-Key: your-secret-root-key\" \\\n  -H \"X-OpenViking-Account: acme\" \\\n  -H \"X-OpenViking-User: alice\"\n```\n\n**Python SDK**\n\n```python\nimport openviking as ov\n\nclient = ov.SyncHTTPClient(\n    url=\"http://localhost:1933\",\n    api_key=\"your-secret-root-key\",\n    account=\"acme\",\n    user=\"alice\",\n)\n```\n\n**ovcli.conf**\n\n```json\n{\n  \"url\": \"http://localhost:1933\",\n  \"api_key\": \"your-secret-root-key\",\n  \"account\": \"acme\",\n  \"user\": \"alice\"\n}\n```\n\n## Roles and Permissions\n\n| Role | Scope | Capabilities |\n|------|-------|-------------|\n| ROOT | Global | All operations + Admin API (create/delete accounts, manage users) |\n| ADMIN | Own account | Regular operations + manage users in own account |\n| USER | Own account | Regular operations (ls, read, find, sessions, etc.) |\n\n## Development Mode\n\nWhen no `root_api_key` is configured, authentication is disabled. All requests are accepted as ROOT with the default account. **This is only allowed when the server binds to localhost** (`127.0.0.1`, `localhost`, or `::1`). If `host` is set to a non-loopback address (e.g. `0.0.0.0`) without a `root_api_key`, the server will refuse to start.\n\n```json\n{\n  \"server\": {\n    \"host\": \"127.0.0.1\",\n    \"port\": 1933\n  }\n}\n```\n\n> **Security note:** The default `host` is `127.0.0.1`. If you need to expose the server on the network, you **must** configure `root_api_key`.\n\n## Unauthenticated Endpoints\n\nThe `/health` endpoint never requires authentication. This allows load balancers and monitoring tools to check server health.\n\n```bash\ncurl http://localhost:1933/health\n```\n\n## Admin API Reference\n\n| Method | Endpoint | Role | Description |\n|--------|----------|------|-------------|\n| POST | `/api/v1/admin/accounts` | ROOT | Create account with first admin |\n| GET | `/api/v1/admin/accounts` | ROOT | List all accounts |\n| DELETE | `/api/v1/admin/accounts/{id}` | ROOT | Delete account |\n| POST | `/api/v1/admin/accounts/{id}/users` | ROOT, ADMIN | Register user |\n| GET | `/api/v1/admin/accounts/{id}/users` | ROOT, ADMIN | List users |\n| DELETE | `/api/v1/admin/accounts/{id}/users/{uid}` | ROOT, ADMIN | Remove user |\n| PUT | `/api/v1/admin/accounts/{id}/users/{uid}/role` | ROOT | Change user role |\n| POST | `/api/v1/admin/accounts/{id}/users/{uid}/key` | ROOT, ADMIN | Regenerate user key |\n\n## Related Documentation\n\n- [Configuration](01-configuration.md) - Config file reference\n- [Deployment](03-deployment.md) - Server setup\n- [API Overview](../api/01-overview.md) - API reference\n"

    "content": "# MCP Integration Guide\n\nOpenViking can be used as an [MCP (Model Context Protocol)](https://modelcontextprotocol.io/) server, allowing any MCP-compatible client to access its memory and resource capabilities.\n\n## Transport Modes\n\nOpenViking supports two MCP transport modes:\n\n| | HTTP (SSE) | stdio |\n|---|---|---|\n| **How it works** | Single long-running server process; clients connect via HTTP | Host spawns a new OpenViking process per session |\n| **Multi-session safe** | ✅ Yes — single process, no lock contention | ⚠️ **No** — multiple processes contend for the same data directory |\n| **Recommended for** | Production, multi-agent, multi-session | Single-session local development only |\n| **Setup complexity** | Requires running `openviking-server` separately | Zero setup — host manages the process |\n\n### Choosing the Right Transport\n\n- **Use HTTP** if your host opens multiple sessions, runs multiple agents, or needs concurrent access.\n- **Use stdio** only for single-session, single-agent local setups where simplicity is the priority.\n\n> ⚠️ **Important:** When an MCP host spawns multiple stdio OpenViking processes (e.g., one per chat session), all instances compete for the same underlying data directory. This causes **lock/resource contention** in the storage layer (AGFS and VectorDB).\n>\n> Symptoms include misleading errors such as:\n> - `Collection 'context' does not exist`\n> - `Transport closed`\n> - Intermittent search failures\n>\n> **The root cause is not a broken index** — it is multiple processes contending for the same storage files. Switch to HTTP mode to resolve this. See [Troubleshooting](#troubleshooting) for details.\n\n## Setup\n\n### Prerequisites\n\n1. OpenViking installed (`pip install openviking` or from source)\n2. A valid configuration file (see [Configuration Guide](01-configuration.md))\n3. For HTTP mode: `openviking-server` running (see [Deployment Guide](03-deployment.md))\n\n### HTTP Mode (Recommended)\n\nStart the OpenViking server first:\n\n```bash\nopenviking-server --config /path/to/config.yaml\n# Default: http://localhost:1933\n```\n\nThen configure your MCP client to connect via HTTP.\n\n### stdio Mode\n\nNo separate server needed — the MCP host spawns OpenViking directly.\n\n## Client Configuration\n\n### Claude Code (CLI)\n\n**HTTP mode:**\n\n```bash\nclaude mcp add openviking \\\n  --transport sse \\\n  \"http://localhost:1933/mcp\"\n```\n\n**stdio mode:**\n\n```bash\nclaude mcp add openviking \\\n  --transport stdio \\\n  -- python -m openviking.server --transport stdio \\\n     --config /path/to/config.yaml\n```\n\n### Claude Desktop\n\nEdit `claude_desktop_config.json`:\n\n**HTTP mode:**\n\n```json\n{\n  \"mcpServers\": {\n    \"openviking\": {\n      \"url\": \"http://localhost:1933/mcp\"\n    }\n  }\n}\n```\n\n**stdio mode:**\n\n```json\n{\n  \"mcpServers\": {\n    \"openviking\": {\n      \"command\": \"python\",\n      \"args\": [\n        \"-m\", \"openviking.server\",\n        \"--transport\", \"stdio\",\n        \"--config\", \"/path/to/config.yaml\"\n      ]\n    }\n  }\n}\n```\n\n### Cursor\n\nIn Cursor Settings → MCP:\n\n**HTTP mode:**\n\n```json\n{\n  \"mcpServers\": {\n    \"openviking\": {\n      \"url\": \"http://localhost:1933/mcp\"\n    }\n  }\n}\n```\n\n**stdio mode:**\n\n```json\n{\n  \"mcpServers\": {\n    \"openviking\": {\n      \"command\": \"python\",\n      \"args\": [\n        \"-m\", \"openviking.server\",\n        \"--transport\", \"stdio\",\n        \"--config\", \"/path/to/config.yaml\"\n      ]\n    }\n  }\n}\n```\n\n### OpenClaw\n\nIn your OpenClaw configuration (`openclaw.json` or `openclaw.yaml`):\n\n**HTTP mode (recommended):**\n\n```json\n{\n  \"mcp\": {\n    \"servers\": {\n      \"openviking\": {\n        \"url\": \"http://localhost:1933/mcp\"\n      }\n    }\n  }\n}\n```\n\n**stdio mode:**\n\n```json\n{\n  \"mcp\": {\n    \"servers\": {\n      \"openviking\": {\n        \"command\": \"python\",\n        \"args\": [\n          \"-m\", \"openviking.server\",\n          \"--transport\", \"stdio\",\n          \"--config\", \"/path/to/config.yaml\"\n        ]\n      }\n    }\n  }\n}\n```\n\n## Available MCP Tools\n\nOnce connected, OpenViking exposes the following MCP tools:\n\n| Tool | Description |\n|------|-------------|\n| `search` | Semantic search across memories and resources |\n| `add_memory` | Store a new memory |\n| `add_resource` | Add a resource (file, text, URL) |\n| `get_status` | Check system health and component status |\n| `list_memories` | Browse stored memories |\n| `list_resources` | Browse stored resources |\n\nRefer to OpenViking's tool documentation for full parameter details.\n\n## Troubleshooting\n\n### `Collection 'context' does not exist`\n\n**Likely cause:** Multiple stdio MCP instances contending for the same data directory.\n\n**Fix:** Switch to HTTP mode. If you must use stdio, ensure only one OpenViking process accesses a given data directory at a time.\n\n### `Transport closed`\n\n**Likely cause:** The MCP stdio process crashed or was killed due to resource contention. Can also occur when a client holds a stale connection after the backend was restarted.\n\n**Fix:**\n1. Switch to HTTP mode to avoid contention.\n2. If using HTTP: reload the MCP connection in your client (restart the session or reconnect).\n\n### Connection refused on HTTP endpoint\n\n**Likely cause:** `openviking-server` is not running, or is running on a different port.\n\n**Fix:** Verify the server is running:\n\n```bash\ncurl http://localhost:1933/health\n# Expected: {\"status\": \"ok\"}\n```\n\n### Authentication errors\n\n**Likely cause:** API key mismatch between client config and server config.\n\n**Fix:** Ensure the API key in your MCP client configuration matches the one in your OpenViking server configuration. See [Authentication Guide](04-authentication.md).\n\n## References\n\n- [MCP Specification](https://modelcontextprotocol.io/)\n- [OpenViking Configuration](01-configuration.md)\n- [OpenViking Deployment](03-deployment.md)\n- [Related issue: stdio contention (#473)](https://github.com/volcengine/OpenViking/issues/473)\n"

    "content": "# Operation Telemetry\n\nOperation telemetry lets you ask OpenViking to return a compact summary of what happened during a request, such as duration, token usage, vector retrieval activity, queue progress, and resource-processing stages.\n\nUse it when you want to:\n\n- debug a slow or unexpected request\n- inspect token or retrieval behavior\n- capture structured execution data in your own logs or observability pipeline\n\n## How it works\n\nTelemetry is opt-in. OpenViking only returns a top-level `telemetry` object when you request it.\n\nTypical response shape:\n\n```json\n{\n  \"status\": \"ok\",\n  \"result\": {\"...\": \"...\"},\n  \"telemetry\": {\n    \"id\": \"tm_xxx\",\n    \"summary\": {\n      \"operation\": \"search.find\",\n      \"status\": \"ok\",\n      \"duration_ms\": 31.2,\n      \"tokens\": {\n        \"total\": 24,\n        \"llm\": {\n          \"input\": 12,\n          \"output\": 6,\n          \"total\": 18\n        }\n      },\n      \"vector\": {\n        \"searches\": 3,\n        \"scored\": 26,\n        \"passed\": 8,\n        \"returned\": 5\n      }\n    }\n  }\n}\n```\n\nNotes:\n\n- `telemetry.id` is an opaque correlation id\n- `telemetry.summary` is the structured payload intended for users\n- summary groups appear only when the operation produced them\n- numeric `0` values are omitted from the response\n\n## Supported operations\n\n### HTTP API\n\nOperation telemetry is currently available on these endpoints:\n\n- `POST /api/v1/search/find`\n- `POST /api/v1/search/search`\n- `POST /api/v1/resources/temp_upload`\n- `POST /api/v1/resources`\n- `POST /api/v1/skills`\n- `POST /api/v1/sessions/{session_id}/commit`\n\n### Python SDK\n\nThe same telemetry model is available from the Python clients for:\n\n- `add_resource(...)`\n- `add_skill(...)`\n- `find(...)`\n- `search(...)`\n- `commit_session(...)`\n- `Session.commit(...)`\n\n## Requesting telemetry\n\n### JSON APIs\n\nFor JSON request bodies, `telemetry` supports these forms:\n\n```json\n{\"telemetry\": true}\n```\n\n```json\n{\"telemetry\": {\"summary\": true}}\n```\n\n`true` and `{\"summary\": true}` both request the same payload: `telemetry.id + telemetry.summary`.\n\nThe object form currently exposes the `summary` switch only.\n\nIf you do not want telemetry, either omit the field or set:\n\n```json\n{\"telemetry\": false}\n```\n\n```json\n{\"telemetry\": {\"summary\": false}}\n```\n\n### Multipart upload API\n\n`POST /api/v1/resources/temp_upload` is a multipart form endpoint. For this endpoint, pass telemetry as a form field:\n\n```bash\ncurl -X POST http://localhost:1933/api/v1/resources/temp_upload \\\n  -H \"X-API-Key: your-key\" \\\n  -F \"file=@./notes.md\" \\\n  -F \"telemetry=true\"\n```\n\nThis endpoint currently accepts the boolean form only.\n\n## Common summary groups\n\nThe top-level summary always includes:\n\n- `operation`\n- `status`\n- `duration_ms`\n\nDepending on the operation, you may also see these groups:\n\n- `tokens`: LLM and embedding token totals\n- `vector`: vector search and filtering counts\n- `resource`: resource ingestion and processing stages\n- `queue`: queue processing counts for wait-mode imports\n- `semantic_nodes`: semantic extraction totals\n- `memory`: memory extraction or dedup summaries\n- `errors`: aggregated error information\n\nIf a group does not apply to the operation, it is omitted.\n\n## Field reference\n\nOnly fields that are actually produced by an operation are returned. Missing groups should be treated as \"not applicable\" rather than as zero.\n\n### Top-level telemetry fields\n\n| Field | Meaning |\n| --- | --- |\n| `telemetry.id` | Opaque correlation id for this

behavior\n\n- OpenViking currently exposes summary-only telemetry to users\n- `{\"telemetry\": {\"events\": true}}` is not a supported public request shape\n- event-stream style selection is not part of the public API\n- `session.commit` supports telemetry only when `wait=true`\n- if you call `session.commit` with `wait=false` and request telemetry, the server returns `INVALID_ARGUMENT`\n- telemetry shape is stable at the top level, but optional summary groups vary by operation\n\n## Related docs\n\n- [Monitoring & Health Checks](05-monitoring.md)\n-

    "content": "# API 概览\n\n本页介绍如何连接 OpenViking 以及所有 API 端点共享的约定。\n\n## 连接 OpenViking\n\nOpenViking 支持三种连接模式：\n\n| 模式 | 使用场景 | 说明 |\n|------|----------|------|\n| **嵌入式** | 本地开发，单进程 | 本地运行，数据存储在本地 |\n| **HTTP** | 连接 OpenViking Server | 通过 HTTP API 连接远程服务 |\n| **CLI** | Shell 脚本、Agent 工具调用 | 通过 CLI 命令连接服务端 |\n\n### 嵌入式模式\n\n```python\nimport openviking as ov\n\nclient = ov.OpenViking(path=\"./data\")\nclient.initialize()\n```\n\n嵌入式模式通过 `ov.conf` 配置 embedding、vlm、storage 等模块。默认路径 `~/.openviking/ov.conf`，也可通过环境变量指定：\n\n```bash\nexport OPENVIKING_CONFIG_FILE=/path/to/ov.conf\n```\n\n最小配置示例：\n\n```json\n{\n  \"embedding\": {\n    \"dense\": {\n      \"api_base\": \"<api-endpoint>\",\n      \"api_key\": \"<your-api-key>\",\n      \"provider\": \"<volcengine|openai|jina>\",\n      \"dimension\": 1024,\n      \"model\": \"<model-name>\"\n    }\n  },\n  \"vlm\": {\n    \"api_base\": \"<api-endpoint>\",\n    \"api_key\": \"<your-api-key>\",\n    \"provider\": \"<volcengine|openai|jina>\",\n    \"model\": \"<model-name>\"\n  }\n}\n```\n\n完整配置选项和各服务商示例见 [配置指南](../guides/01-configuration.md)。\n\n### HTTP 模式\n\n```python\nclient = ov.SyncHTTPClient(\n    url=\"http://localhost:1933\",\n    api_key=\"your-key\",\n    agent_id=\"my-agent\",\n    timeout=120.0,\n)\nclient.initialize()\n```\n\n未显式传入 `url` 时，HTTP 客户端会自动从 `ovcli.conf` 读取连接信息。`ovcli.conf` 是 HTTP 客户端和 CLI 共享的配置文件，默认路径 `~/.openviking/ovcli.conf`，也可通过环境变量指定：\n\n```bash\nexport OPENVIKING_CLI_CONFIG_FILE=/path/to/ovcli.conf\n```\n\n```json\n{\n  \"url\": \"http://localhost:1933\",\n  \"api_key\": \"your-key\",\n  \"agent_id\": \"my-agent\"\n}\n```\n\n| 字段 | 说明 | 默认值 |\n|------|------|--------|\n| `url` | 服务端地址 | （必填） |\n| `api_key` | API Key | `null`（无认证） |\n| `agent_id` | Agent 标识符 | `null` |\n| `timeout` | HTTP 请求超时时间（秒） | `60.0` |\n| `output` | 默认输出格式：`\"table\"` 或 `\"json\"` | `\"table\"` |\n\n详见 [配置指南](../guides/01-configuration.md#ovcliconf)。\n\n### 直接 HTTP（curl）\n\n```bash\ncurl http://localhost:1933/api/v1/fs/ls?uri=viking:// \\\n  -H \"X-API-Key: your-key\"\n```\n\n### CLI 模式\n\nCLI 连接到 OpenViking 服务端，将所有操作暴露为 Shell 命令。CLI 同样从 `ovcli.conf` 读取连接信息（与 HTTP 客户端共享）。\n\n**基本用法**\n\n```bash\nopenviking [全局选项] <command> [参数] [命令选项]\n```\n\n**全局选项**（必须放在命令名之前）\n\n| 选项 | 说明 |\n|------|------|\n| `--output`, `-o` | 输出格式：`table`（默认）、`json` |\n| `--version` | 显示 CLI 版本 |\n\n示例：\n\n```bash\nopenviking -o json ls viking://resources/\n```\n\n## 生命周期\n\n**嵌入式模式**\n\n```python\nimport openviking as ov\n\nclient = ov.OpenViking(path=\"./data\")\nclient.initialize()\n\n# ... 使用 client ...\n\nclient.close()\n```\n\n**HTTP 模式**\n\n```python\nimport openviking as ov\n\nclient = ov.SyncHTTPClient(url=\"http://localhost:1933\")\nclient.initialize()\n\n# ... 使用 client ...\n\nclient.close()\n```\n\n## 认证\n\n详见 [认证指南](../guides/04-authentication.md)。\n\n- **X-API-Key** 请求头：`X-API-Key: your-key`\n- **Bearer** 请求头：`Authorization: Bearer your-key`\n- 如果服务端未配置 API Key，则跳过认证。\n- `/health` 端点始终不需要认证。\n\n## 响应格式\n\n所有 HTTP API 响应遵循统一格式：\n\n**成功**\n\n```json\n{\n  \"status\": \"ok\",\n  \"result\": { ... },\n  \"time\": 0.123\n}\n```\n\n**错误**\n\n```json\n{\n  \"status\": \"error\",\n  \"error\": {\n    \"code\": \"NOT_FOUND\",\n    \"message\": \"Resource not found: viking://resources/nonexistent/\"\n  },\n  \"time\": 0.01\n}\n```\n\n## CLI 输出格式\n\n### Table 模式（默认）\n\n列表数据渲染为表格，非列表数据 fallback 到格式化 JSON：\n\n```bash\nopenviking ls viking://resources/\n# name          size  mode  isDir  uri\n# .abstract.md  100   420   False  viking://resources/.abstract.md\n```\n\n### JSON 模式（`--output json`）\n\n所有命令输出格式化 JSON，与 API 响应的 `result` 结构一致：\n\n```bash\nopenviking -o json ls viking://resources/\n# [{ \"name\": \"...\", \"size\": 100, ... }, ...]\n```\n\n可在 `ovcli.conf` 中设置默认输出格式：\n\n```json\n{\n  \"url\": \"http://localhost:1933\",\n  \"output\": \"json\"\n}\n```\n\n### 紧凑模式（`--compact`, `-c`）\n\n- 当 `--output=json` 时：紧凑 JSON 格式 + `{ok, result}` 包装，适用于脚本\n- 当 `--output=table` 时：对表格输出采取精简表示（如去除空列等）\n\n**JSON 输出 - 成功**\n\n```json\n{\"ok\": true, \"result\": ...}\n```\n\n**JSON 输出 - 错误**\n\n```json\n{\"ok\": false, \"error\": {\"code\": \"NOT_FOUND\", \"message\": \"Resource not found\", \"details\": {}}}\n```\n\n### 特殊情况\n\n- **字符串结果**（`read`、`abstract`、`overview`）：直接打印原文\n- **None 结果**（`mkdir`、`rm`、`mv`）：无输出\n\n### 退出码\n\n| 退出码 | 含义 |\n|--------|------|\n| 0 | 成功 |\n| 1 | 一般错误 |\n| 2 | 配置错误 |\n| 3 | 连接错误 |\n\n## 错误码\n\n| 错误码 | HTTP 状态码 | 说明 |\n|--------|-------------|------|\n| `OK` | 200 | 成功 |\n| `INVALID_ARGUMENT` | 400 | 无效参数 |\n| `INVALID_URI` | 400 | 无效的 Viking URI 格式 |\n| `NOT_FOUND` | 404 | 资源未找到 |\n| `ALREADY_EXISTS` | 409 | 资源已存在 |\n| `UNAUTHENTICATED` | 401 | 缺少或无效的 API Key |\n| `PERMISSION_DENIED` | 403 | 权限不足 |\n| `RESOURCE_EXHAUSTED` | 429 | 超出速率限制 |\n| `FAILED_PRECONDITION` | 412 | 前置条件不满足 |\n| `DEADLINE_EXCEEDED` | 504 | 操作超时 |\n| `UNAVAILABLE` | 503 | 服务不可用 |\n| `INTERNAL` | 500 | 内部服务器错误 |\n| `UNIMPLEMENTED` | 501 | 功能未实现 |\n| `EMBEDDING_FAILED` | 500 | Embedding 生成失败 |\n| `VLM_FAILED` | 500 | VLM 调用失败 |\n| `SESSION_EXPIRED` | 410 | 会话已过期 |\n\n## API 端点\n\n### 系统\n\n| 方法 | 路径 | 说明 |\n|------|------|------|\n| GET | `/health` | 健康检查（无需认证） |\n| GET | `/api/v1/system/status` | 系统状态 |\n| POST | `/api/v1/system/wait` | 等待处理完成 |\n\n### 资源\n\n| 方法 | 路径 | 说明 |\n|------|------|------|\n| POST | `/api/v1/resources` | 添加资源 |\n| POST | `/api/v1/skills` | 添加技能 |\n| POST | `/api/v1/pack/export` | 导出 .ovpack |\n| POST | `/api/v1/pack/import` | 导入 .ovpack |\n\n### 文件系统\n\n| 方法 | 路径 | 说明 |\n|------|------|------|\n| GET | `/api/v1/fs/ls` | 列出目录 |\n| GET | `/api/v1/fs/tree` | 目录树 |\n| GET | `/api/v1/fs/stat` | 资源状态 |\n| POST | `/api/v1/fs/mkdir` | 创建目录 |\n| DELETE | `/api/v1/fs` | 删除资源 |\n| POST | `/api/v1/fs/mv` | 移动资源 |\n\n### 内容\n\n| 方法 | 路径 | 说明 |\n|------|------|------|\n| GET | `/api/v1/content/read` | 读取完整内容（L2） |\n| GET | `/api/v1/content/abstract` | 读取摘要（L0） |\n| GET | `/api/v1/content/overview` | 读取概览（L1） |\n\n### 搜索\n\n| 方法 | 路径 | 说明 |\n|------|------|------|\n| POST | `/api/v1/search/find` | 语义搜索 |\n| POST | `/api/v1/search/search` | 上下文感知搜索 |\n| POST | `/api/v1/search/grep` | 模式搜索 |\n| POST | `/api/v1/search/glob` | 文件模式匹配 |\n\n### 关联\n\n| 方法 | 路径 | 说明 |\n|------|------|------|\n| GET | `/api/v1/relations` | 获取关联 |\n| POST | `/api/v1/relations/link` | 创建链接 |\n| DELETE | `/api/v1/relations/link` | 删除链接 |\n\n### 会话\n\n| 方法 | 路径 | 说明 |\n|------|------|------|\n| POST | `/api/v1/sessions` | 创建会话 |\n| GET | `/api/v1/sessions` | 列出会话 |\n| GET | `/api/v1/sessions/{id}` | 获取会话 |\n| DELETE | `/api/v1/sessions/{id}` | 删除会话 |\n| POST | `/api/v1/sessions/{id}/commit` | 提交会话 |\n| POST | `/api/v1/sessions/{id}/messages` | 添加消息 |\n\n### Observer\n\n| 方法 | 路径 | 说明 |\n|------|------|------|\n| GET | `/api/v1/observer/queue` | 队列状态 |\n| GET | `/api/v1/observer/vikingdb` | VikingDB 状态 |\n| GET | `/api/v1/observer/vlm` | VLM 状态 |\n| GET | `/api/v1/observer/system` | 系统状态 |\n| GET | `/api/v1/debug/health` | 快速健康检查 |\n\n### 管理员（多租户）\n\n| 方法 | 路径 | 说明 |\n|------|------|------|\n| POST | `/api/v1/admin/accounts` | 创建工作区 + 首个 admin（ROOT） |\n| GET | `/api/v1/admin/accounts` | 列出工作区（ROOT） |\n| DELETE | `/api/v1/admin/accounts/{account_id}` | 删除工作区（ROOT） |\n| POST | `/api/v1/admin/accounts/{account_id}/users` | 注册用户（ROOT, ADMIN） |\n| GET | `/api/v1/admin/accounts/{account_id}/users` | 列出用户（ROOT, ADMIN） |\n| DELETE | `/api/v1/admin/accounts/{account_id}/users/{user_id}` | 移除用户（ROOT, ADMIN） |\n| PUT | `/api/v1/admin/accounts/{account_id}/users/{user_id}/role` | 修改用户角色（ROOT） |\n| POST | `/api/v1/admin/accounts/{account_id}/users/{user_id}/key` | 重新生成 User Key（ROOT, ADMIN） |\n\n## 相关文档\n\n- [资源管理](02-resources.md) -

DAG 完成后触发 sync_diff_callback 或 move_temp_to_target_callback\n5. callback 执行完毕 -> 释放 SUBTREE 锁\n```\n\n注意：DAG callback 不在外层加锁。每个 `VikingFS.rm` 和 `VikingFS.mv` 内部各自有独立锁保护。外层锁会与内部锁冲突导致死锁。\n\n**服务重启恢复**：SemanticMsg 持久化在 QueueFS 中。重启后 `SemanticProcessor` 发现 `lifecycle_lock_handle_id` 对应的 handle 不在内存中，会重新获取 SUBTREE 锁。\n\n### session.commit()\n\n| 问题 | 方案 |\n|------|------|\n| 消息已清空但 archive 未写入 -> 对话数据丢失 | Phase 1 无锁（archive 不完整无副作用）+ Phase 2 RedoLog |\n\nLLM 调用耗时不可控（5s~60s+），不能放在持锁操作内。设计拆为两个阶段：\n\n```\nPhase 1 — 归档（无锁）：\n  1. 生成归档摘要（LLM）\n  2. 写 archive（history/archive_N/messages.jsonl + 摘要）\n  3. 清空 messages.jsonl\n  4. 清空内存中的消息列表\n\nPhase 2 — 记忆提取 + 写入（RedoLog）：\n  1. 写 redo 标记（archive_uri、session_uri、用户身份信息）\n  2. 从归档消息提取 memories（LLM）\n  3. 写当前消息状态\n  4. 写 relations\n  5. 直接 enqueue SemanticQueue\n  6. 删除 redo 标记\n```\n\n**崩溃恢复分析**：\n\n| 崩溃时间点 | 状态 | 恢复动作 |\n|-----------|------|---------|\n| Phase 1 写 archive 中途 | 无标记 | archive 不完整，下次 commit 从 history/ 扫描 index，不受影响 |\n| Phase 1 archive 完成但 messages 未清空 | 无标记 | archive 完整 + messages 仍在 = 数据冗余但安全 |\n| Phase 2 记忆提取/写入中途 | redo 标记存在 | 启动恢复：从 archive 重做提取+写入+入队 |\n| Phase 2 完成 | redo 标记已删 | 无需恢复 |\n\n## LockContext\n\n`LockContext` 是**异步**上下文管理器，封装锁的获取和释放：\n\n```python\nfrom openviking.storage.transaction import LockContext, get_lock_manager\n\nlock_manager = get_lock_manager()\n\n# Point 锁（写操作、语义处理）\nasync with LockContext(lock_manager, [path], lock_mode=\"point\"):\n    # 执行操作...\n    pass\n\n# Subtree 锁（删除操作）\nasync with LockContext(lock_manager, [path], lock_mode=\"subtree\"):\n    # 执行操作...\n    pass\n\n# MV 锁（移动操作）\nasync with LockContext(lock_manager, [src], lock_mode=\"mv\", mv_dst_parent_path=dst):\n    # 执行操作...\n    pass\n```\n\n**锁模式**：\n\n| lock_mode | 用途 | 行为 |\n|-----------|------|------|\n| `point` | 写操作、语义处理 | 锁定指定路径；与同路径的任何锁和祖先目录的 SUBTREE 锁冲突 |\n| `subtree` | 删除操作 | 锁定子树根节点；与同路径的任何锁、后代目录的任何锁和祖先目录的 SUBTREE 锁冲突 |\n| `mv` | 移动操作 | 目录移动：源和目标均加 SUBTREE 锁；文件移动：源父目录和目标均加 POINT 锁（通过 `src_is_dir` 控制） |\n\n**异常处理**：`__aexit__` 总是释放锁，不吞异常。获取锁失败时抛出 `LockAcquisitionError`。\n\n## 锁类型（POINT vs SUBTREE）\n\n锁机制使用两种锁类型来处理不同的冲突场景：\n\n| | 同路径 POINT | 同路径 SUBTREE | 后代 POINT | 祖先 SUBTREE |\n|---|---|---|---|---|\n| **POINT** | 冲突 | 冲突 | — | 冲突 |\n| **SUBTREE** | 冲突 | 冲突 | 冲突 | 冲突 |\n\n- **POINT (P)**：用于写操作和语义处理。只锁单个目录。若祖先目录持有 SUBTREE 锁则阻塞。\n- **SUBTREE (S)**：用于删除和移动操作。逻辑上覆盖整个子树，但只在根目录写**一个锁文件**。获取前扫描所有后代和祖先目录确认无冲突锁。\n\n## 锁机制\n\n### 锁协议\n\n锁文件路径：`{path}/.path.ovlock`\n\n锁文件内容（Fencing Token）：\n```\n{handle_id}:{time_ns}:{lock_type}\n```\n\n其中 `lock_type` 为 `P`（POINT）或 `S`（SUBTREE）。\n\n### 获取锁流程（POINT 模式）\n\n```\n循环直到超时（轮询间隔：200ms）：\n    1. 检查目标目录存在\n    2. 检查目标路径是否被其他操作锁定\n       - 陈旧锁？ -> 移除后重试\n       - 活跃锁？ -> 等待\n    3. 检查所有祖先目录是否有 SUBTREE 锁\n       - 陈旧锁？ -> 移除后重试\n       - 活跃锁？ -> 等待\n    4. 写入 POINT (P) 锁文件\n    5.

    "content": "# 常见问题\n\n## 基础概念\n\n### OpenViking 是什么？解决什么问题？\n\nOpenViking 是一个专为 AI Agent 设计的开源上下文数据库。它解决了构建 AI Agent 时的核心痛点：\n\n- **上下文碎片化**：记忆、资源、技能散落各处，难以统一管理\n- **检索效果不佳**：传统 RAG 平铺式存储缺乏全局视野，难以理解完整语境\n- **上下文不可观测**：隐式检索链路如同黑箱，出错时难以调试\n- **记忆迭代有限**：缺乏 Agent 相关的任务记忆和自我进化能力\n\nOpenViking 通过文件系统范式统一管理所有上下文，实现分层供给与自我迭代。\n\n### OpenViking 和传统向量数据库有什么本质区别？\n\n| 维度 | 传统向量数据库 | OpenViking |\n|------|---------------|------------|\n| **存储模型** | 扁平化向量存储 | 层级化文件系统（AGFS） |\n| **检索方式** | 单一向量相似度搜索 | 目录递归检索 + 意图分析 + Rerank |\n| **输出形式** | 原始分块 | 结构化上下文（L0 摘要/L1 概览/L2 详情） |\n| **记忆能力** | 不支持 | 内置 6 种记忆分类，支持自动提取和迭代 |\n| **可观测性** | 黑箱 | 检索轨迹完整可追溯 |\n| **上下文类型** | 仅文档 | Resource + Memory + Skill 三种类型 |\n\n### 什么是 L0/L1/L2 分层模型？为什么需要它？\n\nL0/L1/L2 是 OpenViking 的渐进式内容加载机制，解决了\"海量上下文一次性塞入提示词\"的问题：\n\n| 层级 | 名称 | Token 限制 | 用途 |\n|------|------|-----------|------|\n| **L0** | 摘要 | ~100 tokens | 向量搜索召回、快速过滤、列表展示 |\n| **L1** | 概览 | ~2000 tokens | Rerank 精排、内容导航、决策参考 |\n| **L2** | 详情 | 无限制 | 完整原始内容、按需深度加载 |\n\n这种设计让 Agent 可以先浏览摘要快速定位，再按需加载详情，显著节省 Token 消耗。\n\n### Viking URI 是什么？有什么作用？\n\nViking URI 是 OpenViking 的统一资源标识符，格式为 `viking://{scope}/{path}`。它让系统能精准定位任何上下文：\n\n```\nviking://\n├── resources/              # 知识库：文档、代码、网页等\n│   └── my_project/\n├── user/                   # 用户上下文\n│   └── memories/           # 用户记忆（偏好、实体、事件）\n└── agent/                  # Agent 上下文\n    ├── skills/             # 可调用技能\n    └── memories/           # Agent 记忆（案例、模式）\n```\n\n## 安装与配置\n\n### 环境要求是什么？\n\n- **Python 版本**：3.10 或更高\n- **编译工具**（如果从源码安装或在不支持的平台上）：Go 1.19+, GCC 9+ 或 Clang 11+\n- **必需依赖**：Embedding 模型（推荐火山引擎 Doubao）\n- **可选依赖**：\n  - VLM（视觉语言模型）：用于多模态内容处理和语义提取\n  - Rerank 模型：用于提升检索精度\n\n### 什么是 `binding-client` 和 `http-client`？我该选哪个？\n\n- **`binding-client`（默认值）**：通过 CGO 绑定直接在 Python 进程内运行 AGFS 逻辑。优点是性能极高，无网络延迟；缺点是需要本地有编译好的 AGFS 共享库。\n- **`http-client`**：通过 HTTP 协议与独立的 `agfs-server` 通信。优点是部署解耦，不需要本地编译 Go 代码；缺点是有一定的网络通信开销。\n\n如果你的环境支持编译 Go 代码，或者安装了包含预编译库的 Wheel 包，推荐使用默认的 `binding-client`。\n\n### 遇到 \"AGFS binding library not found\" 错误怎么办？\n\n这通常是因为本地没有编译好的 AGFS 共享库。你可以：\n1. **重新编译安装**：在项目根目录运行 `pip install -e . --force-reinstall`（需要 Go 环境）。\n2. **切换到 HTTP 模式**：在 `ov.conf` 中设置 `storage.agfs.mode = \"http-client\"`，并确保有一个正在运行的 `agfs-server`。\n\n### 如何安装 OpenViking？\n\n```bash\npip install openviking --upgrade --force-reinstall\n```\n\n### 如何配置 OpenViking？\n\n在项目目录创建 `~/.openviking/ov.conf` 配置文件：\n\n```json\n{\n  \"embedding\": {\n    \"dense\": {\n      \"provider\": \"volcengine\",\n      \"api_key\": \"your-api-key\",\n      \"model\": \"doubao-embedding-vision-250615\",\n      \"dimension\": 1024,\n      \"input\": \"multimodal\"\n    }\n  },\n  \"vlm\": {\n    \"provider\": \"volcengine\",\n    \"api_key\": \"your-api-key\",\n    \"model\": \"doubao-seed-2-0-pro-260215\",\n    \"api_base\": \"https://ark.cn-beijing.volces.com/api/v3\"\n  },\n  \"rerank\": {\n    \"provider\": \"volcengine\",\n    \"api_key\": \"your-api-key\",\n    \"model\": \"doubao-rerank-250615\"\n  },\n  \"storage\": {\n    \"workspace\": \"./data\",\n    \"agfs\": { \"backend\": \"local\" },\n    \"vectordb\": { \"backend\": \"local\" }\n  }\n}\n```\n\n配置文件放在默认路径 `~/.openviking/ov.conf` 时自动加载；也可通过环境变量 `OPENVIKING_CONFIG_FILE` 或命令行 `--config` 指定其他路径。详见 [配置指南](../guides/01-configuration.md)。\n\n### 支持哪些 Embedding Provider？\n\n| Provider | 说明 |\n|------|------|\n| `volcengine` | 火山引擎 Embedding API（推荐） |\n| `openai` | OpenAI Embedding API |\n| `vikingdb` | VikingDB Embedding API |\n| `jina` | Jina AI Embedding API |\n| `ollama` | Ollama（本地 OpenAI 兼容服务器，无需 API Key） |\n\n支持 Dense、Sparse 和 Hybrid 三种 Embedding 模式。\n\n## 使用指南\n\n### 如何初始化客户端？\n\n```python\nimport openviking as ov\n\n# 异步客户端（推荐）- 嵌入模式\nclient = ov.AsyncOpenViking(path=\"./my_data\")\nawait client.initialize()\n\n# 异步客户端 - 服务模式\nclient = ov.AsyncHTTPClient(url=\"http://localhost:1933\", api_key=\"your-key\")\nawait client.initialize()\n```\n\nSDK 构造函数仅接受 `url`、`api_key`、`path` 参数。其他配置（embedding、vlm 等）通过 `ov.conf` 配置文件管理。\n\n### 支持哪些文件格式？\n\n| 类型 | 支持格式 |\n|------|----------|\n| **文本** | `.txt`、`.md`、`.json`、`.yaml` |\n| **代码** | `.py`、`.js`、`.ts`、`.go`、`.java`、`.cpp` 等 |\n| **文档** | `.pdf`、`.docx` |\n| **图片** | `.png`、`.jpg`、`.jpeg`、`.gif`、`.webp` |\n| **视频** | `.mp4`、`.mov`、`.avi` |\n| **音频** | `.mp3`、`.wav`、`.m4a` |\n\n### 如何添加资源？\n\n```python\n# 添加单个文件\nawait client.add_resource(\n    \"./document.pdf\",\n    reason=\"项目技术文档\",  # 描述资源用途，提升检索质量\n    target=\"viking://resources/docs/\"  # 指定存储位置\n)\n\n# 添加网页\nawait client.add_resource(\n    \"https://example.com/api-docs\",\n    reason=\"API 参考文档\"\n)\n\n# 等待处理完成\nawait client.wait_processed()\n```\n\n### `find()` 和 `search()` 有什么区别？应该用哪个？\n\n| 特性 | `find()` | `search()` |\n|------|----------|------------|\n| **会话上下文** | 不需要 | 需要 |\n| **意图分析** | 不使用 | 使用 LLM 分析生成 0-5 个查询 |\n| **延迟** | 低 | 较高 |\n| **适用场景** | 简单语义搜索 | 复杂任务、需要理解上下文 |\n\n```python\n# find(): 简单直接的语义搜索\nresults = await client.find(\n    \"OAuth 认证流程\",\n    target_uri=\"viking://resources/\"\n)\n\n# search(): 复杂任务，需要意图分析\nresults = await client.search(\n    \"帮我实现用户登录功能\",\n    session_info=session\n)\n```\n\n**选择建议**：\n- 明确知道要找什么 → 用 `find()`\n- 复杂任务需要多种上下文 → 用 `search()`\n\n### 如何使用会话管理？\n\n会话管理是 OpenViking 的核心能力，支持对话追踪和记忆提取：\n\n```python\n# 创建会话\nsession = client.session()\n\n# 添加对话消息\nawait session.add_message(\"user\", [{\"type\": \"text\", \"text\": \"帮我分析这段代码的性能问题\"}])\nawait session.add_message(\"assistant\", [{\"type\": \"text\", \"text\": \"我来分析一下...\"}])\n\n# 标记使用的上下文（用于追踪）\nawait session.used([\"viking://resources/code/main.py\"])\n\n# 提交会话，触发记忆提取\nawait session.commit()\n```\n\n### OpenViking 支持哪些记忆类型？\n\nOpenViking 内置 6 种记忆分类，在会话提交时自动提取：\n\n| 分类 | 归属 | 说明 |\n|------|------|------|\n| **profile** | user | 用户基本信息（姓名、角色等） |\n| **preferences** | user | 用户偏好（代码风格、工具选择等） |\n| **entities** | user | 实体记忆（人物、项目、组织等） |\n| **events** | user | 事件记录（决策、里程碑等） |\n| **cases** | agent | Agent 学习的案例 |\n| **patterns** | agent | Agent 学习的模式 |\n\n### 如何使用类 Unix 的文件系统 API？\n\n```python\n# 列出目录内容\nitems = await client.ls(\"viking://resources/\")\n\n# 读取完整内容（L2）\ncontent = await client.read(\"viking://resources/doc.md\")\n\n# 获取摘要（L0）\nabstract = await client.abstract(\"viking://resources\")\n\n# 获取概览（L1）\noverview = await client.overview(\"viking://resources\")\n```\n\n## 检索优化\n\n### 如何提升检索质量？\n\n1. **使用 Rerank 模型**：配置 Rerank 可显著提升精排效果\n2. **提供有意义的 `reason`**：添加资源时描述用途，帮助系统理解资源价值\n3. **合理组织目录结构**：使用 `target` 参数将相关资源放在一起\n4. **使用会话上下文**：`search()` 会利用会话历史进行意图分析\n5. **选择合适的 Embedding 模式**：多模态内容使用 `multimodal` 输入\n\n### 检索结果的分数是如何计算的？\n\nOpenViking 使用分数传播机制：\n\n```\n最终分数 = 0.5 × Embedding 相似度 + 0.5 × 父目录分数\n```\n\n这种设计让高分目录下的内容获得加成，体现了\"上下文语境\"的重要性。\n\n### 什么是目录递归检索？\n\n目录递归检索是 OpenViking 的创新检索策略：\n\n1. **意图分析**：分析查询生成多个检索条件\n2. **初始定位**：向量检索定位高分目录\n3. **精细探索**：在高分目录下进行二次检索\n4. **递归下探**：逐层递归直到收敛\n5. **结果汇总**：返回最相关的上下文\n\n这种策略能找到语义匹配的片段，同时理解信息的完整语境。\n\n## 故障排除\n\n### 资源添加后没有被索引\n\n**可能原因及解决方案**：\n\n1. **未等待处理完成**\n   ```python\n   await client.add_resource(\"./doc.pdf\")\n   await client.wait_processed()  # 必须等待\n   ```\n\n2. **Embedding 模型配置错误**\n   - 检查 `~/.openviking/ov.conf` 中的 `api_key` 是否正确\n   - 确认模型名称和 endpoint 配置正确\n\n3. **文件格式不支持**\n   - 检查文件扩展名是否在支持列表中\n   - 确认文件内容有效且未损坏\n\n4. **查看处理日志**\n   ```python\n   import logging\n   logging.basicConfig(level=logging.DEBUG)\n   ```\n\n### 搜索没有返回预期结果\n\n**排查步骤**：\n\n1. **确认资源已处理完成**\n   ```python\n   # 检查资源是否存在\n   items = await client.ls(\"viking://resources/\")\n   ```\n\n2. **检查 `target_uri` 过滤条件**\n   - 确保搜索范围包含目标资源\n   - 尝试扩大搜索范围\n\n3. **尝试不同的查询方式**\n   - 使用更具体或更宽泛的关键词\n   - 尝试 `find()` 和 `search()` 对比效果\n\n4. **检查 L0 摘要质量**\n   ```python\n   abstract = await client.abstract(\"viking://resources/your-doc\")\n   print(abstract)  # 确认摘要是否准确反映内容\n   ```\n\n### 记忆提取不工作\n\n**排查步骤**：\n\n1. **确保调用了 `commit()`**\n   ```python\n   await session.commit()  # 触发记忆提取\n   ```\n\n2. **检查 VLM 配置**\n   - 记忆提取需要 VLM 模型\n   - 确认 `vlm` 配置正确\n\n3. **确认对话内容有意义**\n   - 闲聊内容可能不会产生记忆\n   - 需要包含可提取的信息（偏好、实体、事件等）\n\n4. **查看提取的记忆**\n   ```python\n   memories = await client.find(\"\", target_uri=\"viking://user/memories/\")\n   ```\n\n### 性能问题\n\n**优化建议**：\n\n1. **批量处理**：一次添加多个资源比逐个添加更高效\n2. **合理设置 `batch_size`**：Embedding 配置中调整批处理大小\n3. **使用本地存储**：开发阶段使用 `local` 后端减少网络延迟\n4. **异步操作**：充分利用 `AsyncOpenViking` / `AsyncHTTPClient` 的异步特性\n\n## 部署相关\n\n### 嵌入式模式和服务模式有什么区别？\n\n| 模式 | 适用场景 | 特点 |\n|------|----------|------|\n| **嵌入式** | 本地开发、单进程应用 | 自动启动 AGFS 子进程，使用本地向量索引 |\n| **服务模式** | 生产环境、分布式部署 | 连接远程服务，支持多实例并发，可独立扩展 |\n\n```python\n# 嵌入式模式\nclient = ov.AsyncOpenViking(path=\"./data\")\n\n# 服务模式\nclient = ov.AsyncHTTPClient(url=\"http://localhost:1933\", api_key=\"your-key\")\n```\n\n### OpenViking 是开源的吗？\n\n是的，OpenViking 完全开源，采用 Apache 2.0 许可证。\n\n## 相关文档\n\n- [简介](../getting-started/01-introduction.md) -

    "content": "# 简介\n\n**OpenViking** 是一个开源的、专为 AI Agent 设计的上下文数据库。OpenViking 通过**文件系统范式**统一管理Agent 所需要的上下文（记忆、资源和技能），并实现上下文的**分层供给**与**自我迭代**，最终目标是降低 Agent 开发门槛，让开发者更专注于业务创新而非底层上下文管理。\n\n## 为什么需要 OpenViking\n\n在 AI 时代，数据易得，但高质量的上下文却难求。构建 AI Agent 时，开发者经常遇到这些挑战：\n\n- **上下文碎片化**：记忆在代码里，资源在向量库，技能散落各处，难以统一管理\n- **所需上下文猛增**：Agent 的长程任务在每次执行时都会产出上下文，简单的截断或压缩会导致信息损失\n- **检索效果不佳**：传统 RAG 是平铺式存储，缺乏全局视野，难以理解信息的完整语境\n- **上下文不可观测**：传统 RAG 隐式的检索链路如同黑箱，出错时难以调试\n- **记忆迭代有限**：目前记忆只是用户记忆的记录，缺乏 Agent 相关的任务记忆\n\nOpenViking 正是为解决这些痛点而设计的上下文数据库。\n\n## 核心特性\n\n### 1. 文件系统管理范式\n\n摒弃传统的扁平化数据库思维，将所有上下文组织为一套虚拟文件系统。Agent 不再仅是通过向量搜索来找数据，而是可以通过确定性的路径和标准文件系统指令来定位和浏览数据。\n\n**统一 URI 标识**：每个上下文分配唯一的 `viking://` URI，让系统能精准定位并访问存储在不同位置的资源。\n\n```\nviking://\n├── resources/              # 资源：项目文档、代码库、网页等\n│   └── my_project/\n├── user/                   # 用户：个人偏好、习惯等\n│   └── memories/\n└── agent/                  # Agent：技能、指令、任务记忆等\n    ├── skills/\n    └── memories/\n```\n\n**三种上下文类型**：\n\n| 类型 | 用途 | 生命周期 |\n|------|------|----------|\n| **Resource** | 知识和规则（文档、代码、FAQ） | 长期，相对静态 |\n| **Memory** | Agent 的认知（用户偏好、学习经验） | 长期，动态更新 |\n| **Skill** | 可调用的能力（工具、MCP） | 长期，静态 |\n\n**类 Unix API**：熟悉的命令式操作\n\n```python\nclient.find(\"用户认证\")              # 语义搜索\nclient.ls(\"viking://resources/\")     # 列出目录\nclient.read(\"viking://resources/doc\") # 读取内容\nclient.abstract(\"viking://...\")       # 获取 L0 摘要\nclient.overview(\"viking://...\")       # 获取 L1 概览\n```\n\n### 2. 分层上下文按需加载\n\n将海量上下文一次性塞入提示词，不仅成本高昂，更容易超出模型窗口并引入噪声。OpenViking 在上下文写入时便自动将其处理为三个层级：\n\n| 层级 | 名称 | Token 限制 | 用途 |\n|------|------|-----------|------|\n| **L0** | 摘要 | ~100 tokens | 向量搜索、快速过滤 |\n| **L1** | 概览 | ~2k tokens | Rerank 精排、内容导航 |\n| **L2** | 详情 | 无限制 | 完整内容、按需加载 |\n\n```\nviking://resources/my_project/\n├── .abstract.md               # L0 层：摘要\n├── .overview.md               # L1 层：概览\n├── docs/\n│   ├── .abstract.md          # 每个目录都有对应的 L0/L1 层\n│   ├── .overview.md\n│   └── api.md                # L2 层：完整内容\n└── src/\n```\n\n### 3. 目录递归检索\n\n单一的向量检索难以应对复杂的查询意图。OpenViking 设计了一套创新的**目录递归检索策略**：\n\n1. **意图分析**：通过意图分析生成多个检索条件\n2. **初始定位**：利用向量检索快速定位初始切片所在的高分目录\n3. **精细探索**：在该目录下进行二次检索，并将高分结果更新至候选集合\n4. **递归下探**：若目录下仍存在子目录，则逐层递归重复上述二次检索步骤\n5. **结果汇总**：最终拿到最相关上下文返回\n\n这种\"先锁定高分目录、再精细探索内容\"的策略，不仅能找到语义最匹配的片段，更能理解信息所在的完整语境。\n\n### 4. 可视化检索轨迹\n\nOpenViking 的组织方式采用层次化虚拟文件系统结构，所有上下文均以统一格式整合且每个条目对应唯一 URI，打破传统扁平黑箱式管理模式。\n\n检索过程采用目录递归策略，每次检索的目录浏览、文件定位轨迹均被完整留存，能够清晰观测问题根源并指导检索逻辑优化。\n\n### 5. 会话自动管理\n\nOpenViking 内置了记忆自迭代闭环。在每次会话结束时，开发者可以主动触发记忆提取机制，系统会异步分析任务执行结果与用户反馈，并自动更新至 User 和 Agent 的记忆目录下。\n\n**6 种记忆分类**：\n\n| 分类 | 归属 | 说明 |\n|------|------|------|\n| **profile** | user | 用户基本信息 |\n| **preferences** | user | 按主题的用户偏好 |\n| **entities** | user | 实体记忆（人物、项目） |\n| **events** | user | 事件记录（决策、里程碑） |\n| **cases** | agent | 学习的案例 |\n| **patterns** | agent | 学习的模式 |\n\n让 Agent 在与世界的交互中\"越用越聪明\"，实现自我进化。\n\n## 下一步\n\n- [快速开始](./02-quickstart.md) - 5 分钟上手\n- [架构详解](../concepts/01-architecture.md) - 理解系统设计\n- [上下文类型](../concepts/02-context-types.md) - 深入了解三种上下文\n- [检索机制](../concepts/07-retrieval.md) - 了解检索流程\n"

    "content": "# 快速开始\n\n5 分钟上手 OpenViking。\n\n## 前置要求\n\n在开始使用 OpenViking 之前，请确保您的环境满足以下要求：\n\n- **Python 版本**：3.10 或更高版本\n- **操作系统**：Linux、macOS、Windows\n- **网络连接**：需要稳定的网络连接（用于下载依赖包和访问模型服务）\n\n## 安装与启动\n\nOpenViking 支持通过 Python Package 安装作为本地库使用，也支持通过 Docker 快速启动独立服务。\n\n### 方式一：通过 pip 安装 (作为本地库)\n\n```bash\npip install openviking --upgrade --force-reinstall\n```\n\n### 方式二：通过 Docker 启动 (作为独立服务)\n\n如果你希望将 OpenViking 作为独立的服务运行，推荐使用 Docker。\n\n1. **准备配置文件与数据目录**\n   在宿主机上创建数据目录，并准备好 `ov.conf` 配置文件（配置项参考下方“配置环境”章节）：\n   ```bash\n   mkdir -p ~/.openviking/data\n   touch ~/.openviking/ov.conf\n   ```\n\n2. **使用 Docker Compose 启动**\n   创建 `docker-compose.yml` 文件：\n   ```yaml\n   services:\n     openviking:\n       image: ghcr.io/volcengine/openviking:main\n       container_name: openviking\n       ports:\n         - \"1933:1933\"\n       volumes:\n         - ~/.openviking/ov.conf:/app/ov.conf\n         - ~/.openviking/data:/app/data\n       restart: unless-stopped\n   ```\n   然后在同目录下执行启动命令：\n   ```bash\n   docker-compose up -d\n   ```\n\n> **💡 Mac 本地网络访问提示 (Connection reset 报错)：**\n>\n> 默认情况下，OpenViking 为了安全仅监听 `127.0.0.1`。如果你在 Mac 上使用 Docker，宿主机可能无法直接通过 `localhost:1933` 访问。\n> \n> **推荐解决方案：使用 socat 端口转发（无需修改配置）：**\n> 在你的 `docker-compose.yml` 中覆盖默认启动命令，利用 `socat` 在容器内部进行端口转发：\n> ```yaml\n> services:\n>   openviking:\n>     image: ghcr.io/volcengine/openviking:main\n>     ports:\n>       - \"1933:1934\" # 将宿主机 1933 映射到容器 1934\n>     volumes:\n>       - ~/.openviking/ov.conf:/app/ov.conf\n>       - ~/.openviking/data:/app/data\n>     command: /bin/sh -c \"apt-get update && apt-get install -y socat && socat TCP-LISTEN:1934,fork,reuseaddr TCP:127.0.0.1:1933 & openviking-server\"\n> ```\n> 这样即可完美解决 Mac 宿主机的访问问题。\n\n## 模型准备\n\nOpenViking 需要以下模型能力：\n- **VLM 模型**：用于图像和内容理解\n- **Embedding 模型**：用于向量化和语义检索\n\nOpenViking 支持多种模型服务：\n- **火山引擎（豆包模型）**：推荐使用，成本低、性能好，新用户有免费额度。如需购买和开通，请参考：[火山引擎购买指南](../guides/02-volcengine-purchase-guide.md)\n- **OpenAI 模型**：支持 GPT-4V 等 VLM 模型和 OpenAI Embedding 模型\n- **其他自定义模型服务**：支持兼容 OpenAI API 格式的模型服务\n\n## 配置环境\n\n### 配置文件模版\n\n创建配置文件 `~/.openviking/ov.conf`：\n\n```json\n{\n  \"embedding\": {\n    \"dense\": {\n      \"api_base\" : \"<api-endpoint>\",\n      \"api_key\"  : \"<your-api-key>\",\n      \"provider\" : \"<provider-type>\",\n      \"dimension\": 1024,\n      \"model\"    : \"<model-name>\"\n    }\n  },\n  \"vlm\": {\n    \"api_base\" : \"<api-endpoint>\",\n    \"api_key\"  : \"<your-api-key>\",\n    \"provider\" : \"<provider-type>\",\n    \"model\"    : \"<model-name>\"\n  }\n}\n```\n\n各模型服务的完整配置示例请参见 [配置指南 - 配置示例](../guides/01-configuration.md#配置示例)。\n\n### 设置环境变量\n\n配置文件放在默认路径 `~/.openviking/ov.conf` 时，无需额外设置，OpenViking 会自动加载。\n\n如果配置文件放在其他位置，需要通过环境变量指定：\n\n```bash\nexport OPENVIKING_CONFIG_FILE=/path/to/your/ov.conf\n```\n\n## 运行第一个示例\n\n### 创建 Python 脚本\n\n创建 `example.py`：\n\n```python\nimport openviking as ov\n\n# Initialize OpenViking client with data directory\nclient = ov.OpenViking(path=\"./data\")\n\ntry:\n    # Initialize the client\n    client.initialize()\n\n    # Add resource (supports URL, file, or directory)\n    add_result = client.add_resource(\n        path=\"https://raw.githubusercontent.com/volcengine/OpenViking/refs/heads/main/README.md\"\n    )\n    root_uri = add_result['root_uri']\n\n    # Explore the resource tree structure\n    ls_result = client.ls(root_uri)\n    print(f\"Directory structure:\\n{ls_result}\\n\")\n\n    # Use glob to find markdown files\n    glob_result = client.glob(pattern=\"**/*.md\", uri=root_uri)\n    if glob_result['matches']:\n        content = client.read(glob_result['matches'][0])\n        print(f\"Content preview: {content[:200]}...\\n\")\n\n    # Wait for semantic processing to complete\n    print(\"Wait for semantic processing...\")\n    client.wait_processed()\n\n    # Get abstract and overview of the resource\n    abstract = client.abstract(root_uri)\n    overview = client.overview(root_uri)\n    print(f\"Abstract:\\n{abstract}\\n\\nOverview:\\n{overview}\\n\")\n\n    # Perform semantic search\n    results = client.find(\"what is openviking\", target_uri=root_uri)\n    print(\"Search results:\")\n    for r in results.resources:\n        print(f\"  {r.uri} (score: {r.score:.4f})\")\n\n    # Close the client\n    client.close()\n\nexcept Exception as e:\n    print(f\"Error: {e}\")\n```\n\n### 运行脚本\n\n```bash\npython example.py\n```\n\n### 预期输出\n\n```\nDirectory structure:\n...\n\nContent preview: ...\n\nWait for semantic processing...\nAbstract:\n...\n\nOverview:\n...\n\nSearch results:\n  viking://resources/... (score: 0.8523)\n  ...\n```\n\n恭喜！你已成功运行 OpenViking。\n\n## 服务端模式\n\n想要将 OpenViking 作为共享服务运行？请参见 [快速开始：服务端模式](03-quickstart-server.md)。\n\n## 下一步\n\n- [配置详解](../guides/01-configuration.md) - 详细配置选项\n- [API 概览](../api/01-overview.md) - API 参考\n- [资源管理](../api/02-resources.md) - 资源管理 API\n"

TCP 1933) |\n\n### 2. 系统环境准备（挂载数据盘）\n\n实例启动后，需将数据盘挂载至 `/data` 目录。请在服务器执行以下命令，自动完成格式化与挂载：\n\n```bash\n# 1. 创建挂载点\nmkdir -p /data\n\n# 2. 配置自动挂载 (使用 UUID 防止盘符漂移)\ncp /etc/fstab /etc/fstab.bak\nDISK_UUID=$(blkid -s UUID -o value /dev/vdb)\n\nif [ -z \"$DISK_UUID\" ]; then\n    echo \"ERROR: /dev/vdb UUID not found\"\nelse\n    # 写入 fstab\n    echo \"UUID=${DISK_UUID} /data ext4 defaults,nofail 0 0\" >> /etc/fstab\n    # 验证并挂载\n    mount -a\n    echo \"挂载成功，当前磁盘状态：\"\n    df -Th /data\nfi\n```\n\n### 3. 安装依赖及OpenViking\n\n```\nyum install -y curl git tree\n\n# 第一步：安装 uv\ncurl -LsSf https://astral.sh/uv/install.sh | sh\n\n# 第二步：配置环境变量\necho 'source $HOME/.cargo/env' >> ~/.bashrc\n\n# 配置生效\nsource ~/.bashrc\n\n# 验证安装\nuv --version\n\n# 第三步：在数据盘创建虚拟环境\ncd /data\n\n# 创建名为 ovenv 的虚拟环境\nuv venv ovenv --python 3.11\n\n# 第四步：激活虚拟环境\nsource /data/ovenv/bin/activate\n\n# 第五步：验证\necho \"Ready\"\necho \"Python path: $(which python)\"\necho \"Python version: $(python --version)\"\n```\n\n- 安装 OpenViking：在激活的虚拟环境下安装工具：\n\n```\nuv tool install openviking --upgrade\n```\n\n接下来就可以准备配置了。\n\n### 4. OpenViking 服务端配置与启动\n\n配置 AI 模型并让服务在后台常驻。\n\n#### 准备配置文件\n\n在启动服务之前，先建立配置文件目录和文件。\n\n**创建配置目录：**\n\n```\nmkdir -p ~/.openviking\n```\n**创建并编辑配置文件：**\n\n```\nvim ~/.openviking/ov.conf\n```\n配置文件内容可参考\n```\n{\n  \"embedding\": {\n    \"dense\": {\n      \"api_base\" : \"<api-endpoint>\",   // API endpoint address (e.g., [https://ark.cn-beijing.volces.com/api/v3](https://ark.cn-beijing.volces.com/api/v3))\n      \"api_key\"  : \"<your-api-key>\",   // Model service API Key\n      \"provider\" : \"<provider-type>\",  // Provider type (volcengine or openai)\n      \"dimension\": 1024,               // Vector dimension\n      \"model\"    : \"<model-name>\",     // Embedding model name (e.g., doubao-embedding-vision-250615)\n      \"input\"    : \"multimodal\"        // if use doubao-embedding-vision-250615, should be multimodal\n    }\n  },\n  \"vlm\": {\n    \"api_base\"   : \"<api-endpoint>\",     // API endpoint address (e.g., [https://ark.cn-beijing.volces.com/api/v3](https://ark.cn-beijing.volces.com/api/v3))\n    \"api_key\"    : \"<your-api-key>\",     // Model service API Key\n    \"provider\"   : \"<provider-type>\",    // Provider type (volcengine or openai)\n    \"max_retries\": 2,\n    \"model\"      : \"<model-name>\"        // VLM model name (e.g., doubao-seed-2-0-pro-260215 or gpt-4-vision-preview)\n  }\n}\n```\n- 进入 vim 后按 i 粘贴您的配置内容，完成后按 Esc 输入 :wq 保存退出。\n\n**后台启动服务：**\n\n我们将使用虚拟环境中的程序，并让它在后台运行。\n- 激活虚拟环境\n```\nsource /data/ovenv/bin/activate\n```\n- 创建日志目录\n```\nmkdir -p /data/log/\n```\n- 后台启动并重定向输出：\n```\nnohup openviking-server > /data/log/openviking.log 2>&1 &\n\n# 默认会以执行命令的路径下创建 ./data 存放数据\n# 如果后续希望杀死服务进程记得要清理两个后台服务：pkill openviking; pkill agfs\n```\n可以看到服务在后台常驻运行。当然如果希望重启自动恢复，建议采用 systemctl 启动，此处不赘述。\n服务启动后，可以在 /data 下看到数据文件、日志文件等。\n\n**验证服务状态：**\n\n- 检查进程： 输入以下命令查看程序是否在运行：\n```\nps aux | grep openviking-server\n```\n\n- 查看日志： 如果进程在，看看有没有报错：\n```\ntail -f /data/log/openviking.log # TODO 支持日志滚动\n```\n**配置客户端并测试 (CLI)**\n\n本地注意也要先安装 openviking 才能使用 CLI 工具, 然后在 ovcli.conf 配置好服务端地址\n\n- 准备客户端配置：\n```\nvim ~/.openviking/ovcli.conf\n```\n- 写入以下内容（注意 IP 换成您服务器的 IP地址）：\n```\n{\n  \"url\": \"http://XXX.XXX.XXX.XXX:1933\",\n  \"api_key\": \"your-key\"\n}\n```\n- 执行系统观察命令，监控系统健康状态：\n```\nopenviking observer system\n```\n- 功能测试（上传与查找）\n```\n# 上传测试文件\nopenviking add-resource https://raw.githubusercontent.com/ZaynJarvis/doc-eval/refs/heads/main/text.md\n\n# 列出资源\nopenviking ls viking://resources\n\n# 检索测试\nopenviking find \"who is Alice\"\n```\n\n\n## 下一步\n\n- [服务部署](../guides/03-deployment.md) - 配置、认证和部署选项\n- [API 概览](../api/01-overview.md) - 完整 API 参考\n- [认证](../guides/04-authentication.md) - 使用 API Key 保护你的服务\n"

\"bge_large_zh\",\n      \"ak\": \"your-access-key\",\n      \"sk\": \"your-secret-key\",\n      \"region\": \"cn-beijing\",\n      \"dimension\": 1024\n    }\n  }\n}\n```\n\n**jina provider 配置示例:**\n\n```json\n{\n  \"embedding\": {\n    \"dense\": {\n      \"provider\": \"jina\",\n      \"api_key\": \"jina_xxx\",\n      \"model\": \"jina-embeddings-v5-text-small\",\n      \"dimension\": 1024\n    }\n  }\n}\n```\n\n可用 Jina 模型:\n- `jina-embeddings-v5-text-small`: 677M 参数, 1024 维, 最大序列长度 32768 (默认)\n- `jina-embeddings-v5-text-nano`: 239M 参数, 768 维, 最大序列长度 8192\n\n**本地部署 (GGUF/MLX):** Jina 嵌入模型是开源的, 在 [Hugging Face](https://huggingface.co/jinaai) 上提供 GGUF 和 MLX 格式。可以使用任何 OpenAI 兼容的推理服务器 (如 llama.cpp、MLX、vLLM) 本地运行, 并将 `api_base` 指向本地端点:\n\n```json\n{\n  \"embedding\": {\n    \"dense\": {\n      \"provider\": \"jina\",\n      \"api_key\": \"local\",\n      \"api_base\": \"http://localhost:8080/v1\",\n      \"model\": \"jina-embeddings-v5-text-nano\",\n      \"dimension\": 768\n    }\n  }\n}\n```\n\n获取 API Key: https://jina.ai\n\n#### Sparse Embedding\n\n> **注意：** 火山引擎的 Sparse embedding 从 `doubao-embedding-vision-250615` 模型版本起支持。\n\n```json\n{\n  \"embedding\": {\n    \"sparse\": {\n      \"provider\": \"volcengine\",\n      \"api_key\": \"your-api-key\",\n      \"model\": \"doubao-embedding-vision-250615\"\n    }\n  }\n}\n```\n\n#### Hybrid Embedding\n\n支持两种方式：\n\n**方式一：使用单一混合模型**\n\n```json\n{\n  \"embedding\": {\n    \"hybrid\": {\n      \"provider\": \"volcengine\",\n      \"api_key\": \"your-api-key\",\n      \"model\": \"doubao-embedding-hybrid\",\n      \"dimension\": 1024\n    }\n  }\n}\n```\n\n**方式二：组合 dense + sparse**\n\n```json\n{\n  \"embedding\": {\n    \"dense\": {\n      \"provider\": \"volcengine\",\n      \"api_key\": \"your-api-key\",\n      \"model\": \"doubao-embedding-vision-250615\",\n      \"dimension\": 1024\n    },\n    \"sparse\": {\n      \"provider\": \"volcengine\",\n      \"api_key\": \"your-api-key\",\n      \"model\": \"doubao-embedding-vision-250615\"\n    }\n  }\n}\n```\n\n### vlm\n\n用于语义提取（L0/L1 生成）的视觉语言模型。\n\n```json\n{\n  \"vlm\": {\n    \"provider\": \"volcengine\",\n    \"api_key\": \"your-api-key\",\n    \"model\": \"doubao-seed-2-0-pro-260215\",\n    \"api_base\": \"https://ark.cn-beijing.volces.com/api/v3\"\n  }\n}\n```\n\n**参数**\n\n| 参数 | 类型 | 说明 |\n|------|------|------|\n| `api_key` | str | API Key |\n| `model` | str | 模型名称 |\n| `api_base` | str | API 端点（可选） |\n| `thinking` | bool | 启用思考模式（仅对部分火山模型生效，默认：`false`） |\n| `max_concurrent` | int | 语义处理阶段 LLM 最大并发调用数（默认：`100`） |\n| `extra_headers` | object | 自定义 HTTP 请求头（OpenAI 兼容 provider 可用，可选） |\n| `stream` | bool | 启用流式模式（OpenAI 兼容 provider 可用，默认：`false`） |\n\n**可用模型**\n\n| 模型 | 说明 |\n|------|------|\n| `doubao-seed-2-0-pro-260215` | 推荐用于语义提取 |\n| `doubao-pro-32k` | 用于更长上下文 |\n\n添加资源时，VLM 生成：\n\n1. **L0（摘要）**：~100 token 摘要\n2. **L1（概览）**：~2k token 概览，包含导航信息\n\n如果未配置 VLM，L0/L1 将直接从内容生成（语义性较弱），多模态资源的描述可能有限。\n\n**自定义 HTTP Headers**\n\n对于 OpenAI 兼容的 provider（如 OpenRouter），可以通过 `extra_headers` 添加自定义 HTTP 请求头：\n\n```json\n{\n  \"vlm\": {\n    \"provider\": \"openai\",\n    \"api_key\": \"your-api-key\",\n    \"model\": \"gpt-4o\",\n    \"api_base\": \"https://openrouter.ai/api/v1\",\n    \"extra_headers\": {\n      \"HTTP-Referer\": \"https://your-site.com\",\n      \"X-Title\": \"Your App Name\"\n    }\n  }\n}\n```\n\n常见使用场景：\n- **OpenRouter**: 需要 `HTTP-Referer` 和 `X-Title` 来标识应用\n- **自定义代理**: 添加认证头或追踪头\n- **API 网关**: 添加版本或路由标识\n\n**流式模式**\n\n对于返回 SSE（Server-Sent Events）格式响应的 OpenAI 兼容 provider，启用 `stream` 模式：\n\n```json\n{\n  \"vlm\": {\n    \"provider\": \"openai\",\n    \"api_key\": \"your-api-key\",\n    \"model\": \"gpt-4o\",\n    \"api_base\": \"https://api.example.com/v1\",\n    \"stream\": true\n  }\n}\n```\n\n> **注意**: OpenAI SDK 需要 `stream=true` 才能正确解析 SSE 响应。使用强制返回 SSE 格式的 provider 时，必须将此选项设置为 `true`。\n\n### code\n\n通过 `code_summary_mode` 控制代码文件的摘要生成方式。以下两种写法等价：\n\n```json\n{\n  \"code\": {\n    \"code_summary_mode\": \"ast\"\n  }\n}\n```\n\n```json\n{\n  \"parsers\": {\n    \"code\": {\n      \"code_summary_mode\": \"ast\"\n    }\n  }\n}\n```\n\n将 `code_summary_mode` 设置为以下三个值之一：\n\n| 值 | 说明 | 默认 |\n|----|------|------|\n| `\"ast\"` | 对 ≥100 行的代码文件提取 AST 骨架（类名、方法签名、首行注释、import），跳过 LLM 调用。**推荐用于大规模代码索引** | ✓ |\n| `\"llm\"` | 全部走 LLM 生成摘要（成本较高） | |\n| `\"ast_llm\"` | 先提取 AST 骨架（含完整注释），再将骨架作为上下文辅助 LLM 生成摘要（质量最高，成本居中） | |\n\nAST 提取支持：Python、JavaScript/TypeScript、Rust、Go、Java、C/C++。其他语言、提取失败或骨架为空时自动 fallback 到 LLM。\n\n详见 [代码骨架提取](../concepts/06-extraction.md#代码骨架提取ast-模式)。\n\n### rerank\n\n用于搜索结果精排的 Rerank 模型。\n\n```json\n{\n  \"rerank\": {\n    \"provider\": \"volcengine\",\n    \"api_key\": \"your-api-key\",\n    \"model\": \"doubao-rerank-250615\"\n  }\n}\n```\n\n**OpenAI 兼容提供方（如 DashScope qwen3-rerank）：**\n\n```json\n{\n  \"rerank\": {\n    \"provider\": \"openai\",\n    \"api_key\": \"your-api-key\",\n    \"api_base\": \"https://dashscope.aliyuncs.com/compatible-api/v1/reranks\",\n    \"model\": \"qwen3-rerank\",\n    \"threshold\": 0.1\n  }\n}\n```\n\n| 参数 | 类型 | 说明

使用两个配置文件：\n\n| 配置文件 | 用途 | 默认路径 |\n|---------|------|---------|\n| `ov.conf` | SDK 嵌入模式 + 服务端配置 | `~/.openviking/ov.conf` |\n| `ovcli.conf` | HTTP 客户端和 CLI 连接远程服务端 | `~/.openviking/ovcli.conf` |\n\n配置文件放在默认路径时，OpenViking 自动加载，无需额外设置。\n\n如果配置文件在其他位置，有两种指定方式：\n\n```bash\n# 方式一：环境变量\nexport OPENVIKING_CONFIG_FILE=/path/to/ov.conf\nexport OPENVIKING_CLI_CONFIG_FILE=/path/to/ovcli.conf\n\n# 方式二：命令行参数（仅 serve 命令）\nopenviking-server --config /path/to/ov.conf\n```\n\n### ov.conf\n\n本文档上方各配置段（embedding、vlm、rerank、storage）均属于 `ov.conf`。SDK 嵌入模式和服务端共用此文件。\n\n### ovcli.conf\n\nHTTP 客户端（`SyncHTTPClient` / `AsyncHTTPClient`）和 CLI 工具连接远程服务端的配置文件：\n\n```json\n{\n  \"url\": \"http://localhost:1933\",\n  \"api_key\": \"your-secret-key\",\n  \"agent_id\": \"my-agent\",\n  \"output\": \"table\"\n}\n```\n\n| 字段 | 说明 | 默认值 |\n|------|------|--------|\n| `url` | 服务端地址 | （必填） |\n| `api_key` | API Key 认证（root key 或 user key） | `null`（无认证） |\n| `agent_id` | Agent 标识，用于 agent space 隔离 | `null` |\n| `output` | 默认输出格式：`\"table\"` 或 `\"json\"` | `\"table\"` |\n\n详见 [服务部署](./03-deployment.md)。\n\n## server 段\n\n将 OpenViking 作为 HTTP 服务运行时，在 `ov.conf` 中添加 `server` 段：\n\n```json\n{\n  \"server\": {\n    \"host\": \"0.0.0.0\",\n    \"port\": 1933,\n    \"root_api_key\": \"your-secret-root-key\",\n    \"cors_origins\": [\"*\"]\n  }\n}\n```\n\n| 字段 | 类型 | 说明 | 默认值 |\n|------|------|------|--------|\n| `host` | str | 绑定地址 | `0.0.0.0` |\n| `port` | int | 绑定端口 | `1933` |\n| `root_api_key` | str | Root API Key，启用多租户认证，不设则为开发模式 | `null` |\n| `cors_origins` | list | CORS 允许的来源 | `[\"*\"]` |\n\n配置 `root_api_key` 后，服务端启用多租户认证。通过 Admin API 创建工作区和用户 key。不配置时为开发模式，不需要认证。\n\n启动方式和部署详情见 [服务部署](./03-deployment.md)，认证详情见 [认证](./04-authentication.md)。\n\n## storage.transaction 段\n\n路径锁默认启用，通常无需配置。**默认行为是不等待**：若目标路径已被其他操作锁定，操作立即失败并抛出 `LockAcquisitionError`。若需要等待重试，请将 `lock_timeout` 设为正数。\n\n```json\n{\n  \"storage\": {\n    \"transaction\": {\n      \"lock_timeout\": 5.0,\n      \"lock_expire\": 300.0\n    }\n  }\n}\n```\n\n| 参数 | 类型 | 说明 | 默认值 |\n|------|------|------|--------|\n| `lock_timeout` | float | 获取路径锁的等待超时（秒）。`0` = 立即失败（默认）；`> 0` = 最多等待此时间后抛出 `LockAcquisitionError` | `0.0` |\n| `lock_expire` | float | 锁过期时间（秒）。超过此时间的锁将被视为崩溃进程遗留的陈旧锁并强制释放 | `300.0` |\n\n路径锁机制的详细说明见 [路径锁与崩溃恢复](../concepts/09-transaction.md)。\n\n## 完整 Schema\n\n```json\n{\n  \"embedding\": {\n    \"max_concurrent\": 10,\n    \"dense\": {\n      \"provider\": \"volcengine\",\n      \"api_key\": \"string\",\n      \"model\": \"string\",\n

    "content": "# MCP 集成指南\n\nOpenViking 可以作为 [MCP (Model Context Protocol)](https://modelcontextprotocol.io/) 服务器使用，任何兼容 MCP 的客户端都可以访问其记忆和资源能力。\n\n## 传输模式\n\nOpenViking 支持两种 MCP 传输模式：\n\n| | HTTP (SSE) | stdio |\n|---|---|---|\n| **工作方式** | 单个长期运行的服务器进程；客户端通过 HTTP 连接 | 宿主为每个会话生成一个新的 OpenViking 进程 |\n| **多会话安全** | ✅ 是 — 单进程，无锁竞争 | ⚠️ **否** — 多进程争用同一数据目录 |\n| **推荐用于** | 生产环境、多 Agent、多会话 | 仅限单会话本地开发 |\n| **配置复杂度** | 需要单独运行 `openviking-server` | 零配置 — 宿主管理进程 |\n\n### 选择合适的传输模式\n\n- **使用 HTTP**：如果你的宿主会打开多个会话、运行多个 Agent，或需要并发访问。\n- **使用 stdio**：仅在单会话、单 Agent 的本地环境中，且追求简单时使用。\n\n> ⚠️ **重要提示：** 当 MCP 宿主为每个会话生成独立的 stdio OpenViking 进程时（例如每个聊天会话一个进程），所有实例会争用同一底层数据目录。这会导致存储层（AGFS 和 VectorDB）的 **锁/资源竞争**。\n>\n> 表现为以下误导性错误：\n> - `Collection 'context' does not exist`\n> - `Transport closed`\n> - 间歇性搜索失败\n>\n> **根因不是索引损坏** — 而是多个进程争用同一存储文件。切换到 HTTP 模式即可解决。详见[故障排除](#故障排除)。\n\n## 配置\n\n### 前提条件\n\n1. 已安装 OpenViking（`pip install openviking` 或从源码安装）\n2. 有效的配置文件（参见[配置指南](01-configuration.md)）\n3. HTTP 模式需要：`openviking-server` 正在运行（参见[部署指南](03-deployment.md)）\n\n### HTTP 模式（推荐）\n\n首先启动 OpenViking 服务器：\n\n```bash\nopenviking-server --config /path/to/config.yaml\n# 默认地址：http://localhost:1933\n```\n\n然后配置你的 MCP 客户端通过 HTTP 连接。\n\n### stdio 模式\n\n无需单独启动服务器 — MCP 宿主直接启动 OpenViking。\n\n## 客户端配置\n\n### Claude Code (CLI)\n\n**HTTP 模式：**\n\n```bash\nclaude mcp add openviking \\\n  --transport sse \\\n  \"http://localhost:1933/mcp\"\n```\n\n**stdio 模式：**\n\n```bash\nclaude mcp add openviking \\\n  --transport stdio \\\n  -- python -m openviking.server --transport stdio \\\n     --config /path/to/config.yaml\n```\n\n### Claude Desktop\n\n编辑 `claude_desktop_config.json`：\n\n**HTTP 模式：**\n\n```json\n{\n  \"mcpServers\": {\n    \"openviking\": {\n      \"url\": \"http://localhost:1933/mcp\"\n    }\n  }\n}\n```\n\n**stdio 模式：**\n\n```json\n{\n  \"mcpServers\": {\n    \"openviking\": {\n      \"command\": \"python\",\n      \"args\": [\n        \"-m\", \"openviking.server\",\n        \"--transport\", \"stdio\",\n        \"--config\", \"/path/to/config.yaml\"\n      ]\n    }\n  }\n}\n```\n\n### Cursor\n\n在 Cursor 设置 → MCP 中配置：\n\n**HTTP 模式：**\n\n```json\n{\n  \"mcpServers\": {\n    \"openviking\": {\n      \"url\": \"http://localhost:1933/mcp\"\n    }\n  }\n}\n```\n\n**stdio 模式：**\n\n```json\n{\n  \"mcpServers\": {\n    \"openviking\": {\n      \"command\": \"python\",\n      \"args\": [\n        \"-m\", \"openviking.server\",\n        \"--transport\", \"stdio\",\n        \"--config\", \"/path/to/config.yaml\"\n      ]\n    }\n  }\n}\n```\n\n### OpenClaw\n\n在 OpenClaw 配置文件（`openclaw.json` 或 `openclaw.yaml`）中：\n\n**HTTP 模式（推荐）：**\n\n```json\n{\n  \"mcp\": {\n    \"servers\": {\n      \"openviking\": {\n        \"url\": \"http://localhost:1933/mcp\"\n      }\n    }\n  }\n}\n```\n\n**stdio 模式：**\n\n```json\n{\n  \"mcp\": {\n    \"servers\": {\n      \"openviking\": {\n        \"command\": \"python\",\n        \"args\": [\n          \"-m\", \"openviking.server\",\n          \"--transport\", \"stdio\",\n          \"--config\", \"/path/to/config.yaml\"\n        ]\n      }\n    }\n  }\n}\n```\n\n## 可用的 MCP 工具\n\n连接后，OpenViking 提供以下 MCP 工具：\n\n| 工具 | 说明 |\n|------|------|\n| `search` | 跨记忆和资源的语义搜索 |\n| `add_memory` | 存储新记忆 |\n| `add_resource` | 添加资源（文件、文本、URL） |\n| `get_status` | 检查系统健康状态和组件状态 |\n| `list_memories` | 浏览已存储的记忆 |\n| `list_resources` | 浏览已存储的资源 |\n\n完整参数详情请参考 OpenViking 的工具文档。\n\n## 故障排除\n\n### `Collection 'context' does not exist`\n\n**可能原因：** 多个 stdio MCP 实例争用同一数据目录。\n\n**解决方案：** 切换到 HTTP 模式。如果必须使用 stdio，请确保同一时间只有一个 OpenViking 进程访问给定的数据目录。\n\n### `Transport closed`\n\n**可能原因：** MCP stdio 进程因资源竞争而崩溃或被终止。也可能发生在后端重启后客户端持有过期连接时。\n\n**解决方案：**\n1. 切换到 HTTP 模式以避免竞争。\n2. 如果使用 HTTP：在客户端中重新加载 MCP 连接（重启会话或重新连接）。\n\n### HTTP 端点连接被拒绝\n\n**可能原因：** `openviking-server` 未运行，或运行在不同端口上。\n\n**解决方案：** 验证服务器是否正在运行：\n\n```bash\ncurl http://localhost:1933/health\n# 预期返回：{\"status\": \"ok\"}\n```\n\n### 认证错误\n\n**可能原因：** 客户端配置与服务器配置中的 API 密钥不匹配。\n\n**解决方案：** 确保 MCP 客户端配置中的 API 密钥与 OpenViking 服务器配置中的一致。参见[认证指南](04-authentication.md)。\n\n## 参考\n\n- [MCP 规范](https://modelcontextprotocol.io/)\n- [OpenViking 配置](01-configuration.md)\n- [OpenViking 部署](03-deployment.md)\n- [相关 Issue：stdio 竞争问题 (#473)](https://github.com/volcengine/OpenViking/issues/473)\n"

    "content": "# 操作级 Telemetry 使用指南\n\n操作级 telemetry 用来让 OpenViking 在请求结果里额外返回一份结构化摘要，帮助你了解这次操作实际发生了什么，例如耗时、token 消耗、向量检索情况、队列处理进度，以及资源导入阶段统计。\n\n适合这些场景：\n\n- 排查请求为什么变慢\n- 观察 token 或检索行为\n- 把结构化执行摘要接入你自己的日志或观测系统\n\n## 基本说明\n\nTelemetry 是按需返回的。只有你显式请求时，OpenViking 才会在响应顶层返回 `telemetry` 字段。\n\n典型响应结构如下：\n\n```json\n{\n  \"status\": \"ok\",\n  \"result\": {\"...\": \"...\"},\n  \"telemetry\": {\n    \"id\": \"tm_xxx\",\n    \"summary\": {\n      \"operation\": \"search.find\",\n      \"status\": \"ok\",\n      \"duration_ms\": 31.2,\n      \"tokens\": {\n        \"total\": 24,\n        \"llm\": {\n          \"input\": 12,\n          \"output\": 6,\n          \"total\": 18\n        }\n      },\n      \"vector\": {\n        \"searches\": 3,\n        \"scored\": 26,\n        \"passed\": 8,\n        \"returned\": 5\n      }\n    }\n  }\n}\n```\n\n说明：\n\n- `telemetry.id` 是不透明的关联 ID\n- `telemetry.summary` 是面向调用方的结构化摘要\n- 只有本次操作实际产出的分组才会返回\n- 数值型 `0` 默认不会出现在响应里\n\n## 当前支持范围\n\n### HTTP API\n\n当前这些接口支持 operation telemetry：\n\n- `POST /api/v1/search/find`\n- `POST /api/v1/search/search`\n- `POST /api/v1/resources/temp_upload`\n- `POST /api/v1/resources`\n- `POST /api/v1/skills`\n- `POST /api/v1/sessions/{session_id}/commit`\n\n### Python SDK\n\nPython 客户端里，下面这些调用支持相同的 telemetry 语义：\n\n- `add_resource(...)`\n- `add_skill(...)`\n- `find(...)`\n- `search(...)`\n- `commit_session(...)`\n- `Session.commit(...)`\n\n## 如何请求 telemetry\n\n### JSON 请求\n\n对于 JSON body，`telemetry` 支持下面两种常用写法：\n\n```json\n{\"telemetry\": true}\n```\n\n```json\n{\"telemetry\": {\"summary\": true}}\n```\n\n`true` 和 `{\"summary\": true}` 的效果相同，都会返回 `telemetry.id + telemetry.summary`。\n\n对象形态当前只开放 `summary` 这个开关。\n\n如果不想返回 telemetry，可以省略该字段，或者显式传：\n\n```json\n{\"telemetry\": false}\n```\n\n```json\n{\"telemetry\": {\"summary\": false}}\n```\n\n### Multipart 上传请求\n\n`POST /api/v1/resources/temp_upload` 是 multipart form 接口。这个接口需要把 telemetry 当作表单字段传入：\n\n```bash\ncurl -X POST http://localhost:1933/api/v1/resources/temp_upload \\\n  -H \"X-API-Key: your-key\" \\\n  -F \"file=@./notes.md\" \\\n  -F \"telemetry=true\"\n```\n\n这个接口当前只支持布尔形态的表单参数。\n\n## 常见 summary 分组\n\nsummary 顶层这 3 个基础字段总会存在：\n\n- `operation`\n- `status`\n- `duration_ms`\n\n根据不同操作，还可能出现这些分组：\n\n- `tokens`：LLM 和 embedding 的 token 统计\n- `vector`：向量检索与过滤统计\n- `resource`：资源导入与处理阶段摘要\n- `queue`：等待模式下的队列处理统计\n- `semantic_nodes`：语义节点提取统计\n- `memory`：记忆提取或去重摘要\n- `errors`：聚合后的错误信息\n\n如果某个分组对本次操作不适用，就不会返回。\n\n## 字段说明\n\n只有这次操作实际产出的字段才会返回。某个分组缺失时，应理解为“不适用”，而不是默认等于 0。\n\n### 顶层 telemetry 字段\n\n| 字段 | 含义 |\n| --- | --- |\n| `telemetry.id` | 本次操作的不透明关联 ID |\n| `summary.operation` | 操作名，例如

`{\"telemetry\": {\"events\": true}}` 不是当前支持的公开请求形态\n- 事件流风格的选择参数不属于当前公开接口\n- `session.commit` 只有在 `wait=true` 时才支持 telemetry\n- 如果 `session.commit` 使用 `wait=false` 并请求 telemetry，服务端会返回 `INVALID_ARGUMENT`\n- telemetry 的顶层结构稳定，但具体有哪些 summary 分组取决于实际操作\n\n## 相关文档\n\n- [监控与健康检查](05-monitoring.md)\n- [认证](04-authentication.md)\n- [系统 API](../api/07-system.md)\n"

    "content": "# OpenViking 云上部署指南（火山引擎）\n\n本文档介绍如何将 OpenViking 部署到火山引擎云上，使用 TOS（对象存储）+ VikingDB（向量数据库）+ 方舟大模型作为后端。\n\n## 概览\n\n云上部署架构：\n\n```\n用户请求 → OpenViking Server (1933)\n                ├── AGFS → TOS (S3 兼容协议，存储文件数据)\n                ├── VectorDB → VikingDB (向量检索)\n                ├── Embedding → 方舟 API (doubao-embedding-vision)\n                └── VLM → 方舟 API (doubao-seed)\n```\n\n> **地域说明**：TOS 和 VikingDB 均需要选择地域（region），不同地域对应不同的服务域名。所有云服务应部署在同一地域以降低网络延迟。目前支持的地域包括 `cn-beijing`、`cn-shanghai`、`cn-guangzhou` 等，本文以 `cn-beijing` 为例。\n\n## 前置条件\n\n- 火山引擎账号（[注册地址](https://console.volcengine.com/)）\n- 已安装 OpenViking（`pip install openviking --upgrade --force-reinstall` 或从源码安装）\n- Python 3.11+\n\n---\n\n## 1. 开通云服务\n\n### 1.1 开通 TOS（对象存储）\n\nTOS 用于持久化存储 OpenViking 的文件数据（AGFS 后端）。\n\n1. 登录 [火山引擎控制台](https://console.volcengine.com/)\n2. 进入 **对象存储 TOS** → 开通服务\n3. 创建存储桶：\n   - 桶名称：如 `openvikingdata`\n   - 地域：如 `cn-beijing`（需与 VikingDB 等其他服务保持一致）\n   - 存储类型：标准存储\n   - 访问权限：私有\n4. 记录桶名称、地域和 S3 兼容 endpoint，填入配置文件的 `storage.agfs.s3` 部分\n\n> **注意**：AGFS 使用 S3 兼容协议访问 TOS，endpoint 需要使用 S3 兼容域名（带 `tos-s3-` 前缀），而非 TOS 控制台显示的标准域名。不同地域的 endpoint 不同，请查阅 [TOS 地域和访问域名文档](https://www.volcengine.com/docs/6349/107356) 获取你所在地域的 S3 兼容 endpoint。例如：\n>\n> | 地域 | S3 兼容 endpoint |\n> |------|-----------------|\n> | cn-beijing | `https://tos-s3-cn-beijing.volces.com` |\n> | cn-shanghai | `https://tos-s3-cn-shanghai.volces.com` |\n> | cn-guangzhou | `https://tos-s3-cn-guangzhou.volces.com` |\n\n### 1.2 开通 VikingDB（向量数据库）\n\nVikingDB 用于存储和检索向量嵌入。\n\n1. 登陆 [火山引擎控制台](https://console.volcengine.com/) →  [进入 VikingDB 下单开通界面](https://console.volcengine.com/vikingdb/region:vikingdb+cn-beijing/home) -> 选择对应的地域并开通向量数据库\n2. 开通服务（按量付费即可），选择与 TOS 相同的地域\n3. 无需手动创建 Collection，OpenViking 启动后会自动创建\n4. 在配置文件中填写 `storage.vectordb.volcengine.region`，OpenViking 会自动路由到对应地域的 VikingDB 服务\n\n### 1.3 申请 AK/SK（IAM 访问密钥）\n\nAK/SK 同时用于 TOS 和 VikingDB 的鉴权。\n\n1. 进入 [火山引擎控制台](https://console.volcengine.com/) → **访问控制 IAM**\n2. 创建子用户（建议不使用主账号 AK/SK）\n3. 为子用户授权以下策略：\n   - `TOSFullAccess`（或精确到桶级别的自定义策略）\n   - `VikingDBFullAccess`\n4. 为子用户创建 **AccessKey**，记录：\n   - `Access Key ID`（即 AK）\n   - `Secret Access Key`（即 SK）\n5. 将 AK/SK 填入配置文件中的以下位置：\n   - `storage.vectordb.volcengine.ak` / `sk`\n   - `storage.agfs.s3.access_key` / `secret_key`\n\n### 1.4 申请方舟 API Key\n\n方舟平台提供 Embedding 和 VLM 模型的推理服务。\n\n1. 进入 [火山方舟控制台](https://console.volcengine.com/ark)\n2. 左侧菜单 → **API Key 管理** → 创建 API Key\n3. 记录生成的 API Key\n4. 确认以下模型已开通（在 **模型广场** 中申请）：\n   - `doubao-embedding-vision-250615`（多模态 Embedding）\n   - `doubao-seed-2-0-pro-260215`（VLM 推理）\n5. 将 API Key 填入配置文件的 `embedding.dense.api_key` 和 `vlm.api_key`\n\n---\n\n## 2. 准备配置文件\n\n### 2.1 复制示例配置\n\n```bash\ncp examples/cloud/ov.conf.example examples/cloud/ov.conf\n```\n\n### 2.2 编辑配置\n\n打开 `examples/cloud/ov.conf`，将占位符替换为真实值。需要替换的字段如下：\n\n| 占位符 | 替换为 | 说明 |\n|--------|--------|------|\n| `<your-root-api-key>` | 自定义强密码 | 管理员密钥，用于多租户管理 |\n| `<your-volcengine-ak>` | IAM Access Key ID | 火山引擎 AK，用于 TOS / VikingDB |\n| `<your-volcengine-sk>` | IAM Secret Access Key | 火山引擎 SK |\n| `<your-tos-bucket>` | TOS 桶名称 | 如 `openvikingdata` |\n| `<your-ark-api-key>` | 方舟 API Key | 用于 Embedding 和 VLM |\n\n此外，还需根据实际地域修改以下字段（示例中默认为 `cn-beijing`）：\n\n| 字段 | 说明 |\n|------|------|\n| `storage.vectordb.volcengine.region` | VikingDB 地域，如 `cn-beijing`、`cn-shanghai`、`cn-guangzhou` |\n| `storage.agfs.s3.region` | TOS 地域，需与桶所在地域一致 |\n| `storage.agfs.s3.endpoint` | TOS 的 S3 兼容 endpoint，需与地域匹配（参考第 1.1 节） |\n\n替换后的配置示例（脱敏）：\n\n```json\n{\n  \"server\": {\n    \"root_api_key\": \"my-strong-secret-key-2024\"\n  },\n  \"storage\": {\n    \"vectordb\": {\n      \"volcengine\": {\n        \"region\": \"cn-beijing\",\n        \"ak\": \"AKLTxxxxxxxxxxxx\",\n        \"sk\": \"T1dYxxxxxxxxxxxx\"\n      }\n    },\n    \"agfs\": {\n      \"s3\": {\n        \"bucket\": \"openvikingdata\",\n        \"region\": \"cn-beijing\",\n        \"access_key\": \"AKLTxxxxxxxxxxxx\",\n        \"secret_key\": \"T1dYxxxxxxxxxxxx\",\n        \"endpoint\": \"https://tos-s3-cn-beijing.volces.com\"\n      }\n    }\n  },\n  \"embedding\": {\n    \"dense\": {\n      \"api_key\": \"xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx\"\n    }\n  },\n  \"vlm\": {\n    \"api_key\": \"xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx\"\n  }\n}\n```\n\n> **注意**：`ov.conf` 已被 `.gitignore` 排除，不会被提交到版本库。请妥善保管你的凭据。\n\n---\n\n## 3. 启动服务\n\n| 方式 | 需要容器运行时 | 适合节点数 | 环境隔离 | 弹性伸缩 | 典型场景 |\n|------|:---:|:---:|:---:|:---:|------|\n| **Docker（推荐）** | 是 | 单机 | 容器隔离 | 不支持 | 开发、测试、单机生产，最省事 |\n| systemd | 否 | 单机 | 无 | 不支持 | VM 上不想装 Docker |\n| Kubernetes + Helm | 是 | 暂不支持多节点 | 容器 + 编排 | 支持 | 已有 K8s 集群的团队 |\n\n> **开发调试**：如果只是本地快速验证，可以直接运行：\n> ```bash\n> pip install openviking --upgrade --force-reinstall\n>\n> # 方式 A：放到默认路径\n> mkdir -p ~/.openviking && cp examples/cloud/ov.conf ~/.openviking/ov.conf\n> openviking-server\n>\n> # 方式 B：通过环境变量指定\n> OPENVIKING_CONFIG_FILE=examples/cloud/ov.conf openviking-server\n> ```\n\n### 方式一：systemd\n\n适合在 VM 上以系统服务方式长期运行。\n\n1. 安装 OpenViking：\n\n```bash\npip install openviking --upgrade --force-reinstall\n```\n\n2. 将配置文件放到固定路径：\n\n```bash\nsudo mkdir -p /etc/openviking\nsudo cp ~/.openviking/ov.conf /etc/openviking/ov.conf\nsudo chmod 600 /etc/openviking/ov.conf\n```\n\n3. 创建 systemd service 文件：\n\n```bash\nsudo tee /etc/systemd/system/openviking.service > /dev/null << 'EOF'\n[Unit]\nDescription=OpenViking Server\nAfter=network.target\n\n[Service]\nType=simple\nEnvironment=OPENVIKING_CONFIG_FILE=/etc/openviking/ov.conf\nExecStart=/usr/local/bin/openviking-server  # 替换为 which openviking-server 的实际输出\nRestart=on-failure\nRestartSec=5s\nStandardOutput=journal\nStandardError=journal\nNoNewPrivileges=true\nPrivateTmp=true\n\n[Install]\nWantedBy=multi-user.target\nEOF\n```\n\n4. 启动服务：\n\n```bash\nsudo systemctl daemon-reload\nsudo systemctl start openviking\nsudo systemctl status openviking\n```\n\n5. 确认服务正常后，设置开机自启（可选）：\n\n```bash\nsudo systemctl enable openviking\n```\n\n常用管理命令：\n\n```bash\nsudo systemctl stop openviking       # 停止服务\nsudo systemctl restart openviking    # 重启服务\njournalctl -u openviking -f          # 查看实时日志\n```\n\n### 方式二：Docker\n\n单容器场景用 `docker run` 或 `docker compose` 均可，效果相同。\n\n**docker run：**\n\n```bash\n# 假设你的配置文件在 ~/.openviking/ov.conf\n#\n# -p  端口映射，宿主机端口:容器端口，启动后通过 localhost:1933 访问\n# -v  挂载宿主机文件到容器内，格式为 宿主机路径:容器内路径\n#     ov.conf 挂载是必填的，data 目录用于持久化数据（容器删除后不丢失）\n# --restart  进程崩溃或机器重启后自动拉起\n\ndocker run -d \\\n  --name openviking \\\n  -p 1933:1933 \\\n  -v ~/.openviking/ov.conf:/app/ov.conf \\\n  -v /var/lib/openviking/data:/app/data \\\n  --restart unless-stopped \\\n  ghcr.io/volcengine/openviking:main\n```\n\n> 将 `~/.openviking/ov.conf` 替换为你实际的配置文件路径。\n\n常用管理命令：\n\n```bash\ndocker logs openviking        # 查看日志\ndocker logs -f openviking     # 实时跟踪日志\ndocker stop openviking        # 停止服务\ndocker restart openviking     # 重启服务\ndocker rm -f openviking       # 删除容器（重新 docker run 前需要先删除）\n```\n\n**docker compose：**\n\n项目根目录的 `docker-compose.yml` 默认从 `/var/lib/openviking/ov.conf` 读取配置：\n\n```bash\n# 把你的配置文件复制到 docker-compose.yml 期望的路径\nsudo mkdir -p /var/lib/openviking\nsudo cp ~/.openviking/ov.conf /var/lib/openviking/ov.conf\n\n# 在项目根目录下启动（-d 表示后台运行）\ndocker compose up -d\n```\n\n> 如果配置文件不在 `/var/lib/openviking/ov.conf`，需要修改 `docker-compose.yml` 中 `volumes` 的挂载路径。\n\n常用管理命令：\n\n```bash\ndocker compose stop        # 停止服务\ndocker compose restart     # 重启服务\ndocker compose logs -f     # 查看实时日志\n```\n\n> 如需自行构建镜像：`docker build -t openviking:latest .`\n\n### 方式三：Kubernetes + Helm\n\nHelm chart 默认的 `values.yaml` 只包含 embedding 和 vlm 配置。云上部署需要补充 storage、server 等字段。\n\n推荐创建自定义 values 文件 `my-values.yaml`：\n\n```yaml\nopenviking:\n  config:\n    server:\n      root_api_key: \"my-strong-secret-key-2024\"\n    storage:\n      workspace: /app/data\n      vectordb:\n        name: context\n        backend: volcengine\n        project: default\n

-f my-values.yaml\n```\n\n或者通过 `--set` 逐个传参（适合 CI/CD）：\n\n```bash\nhelm install openviking ./examples/k8s-helm \\\n  --set openviking.config.server.root_api_key=\"my-strong-secret-key-2024\" \\\n  --set openviking.config.embedding.dense.api_key=\"YOUR_ARK_API_KEY\" \\\n  --set openviking.config.vlm.api_key=\"YOUR_ARK_API_KEY\" \\\n  --set openviking.config.storage.vectordb.backend=\"volcengine\" \\\n  --set openviking.config.storage.vectordb.volcengine.ak=\"YOUR_AK\" \\\n  --set openviking.config.storage.vectordb.volcengine.sk=\"YOUR_SK\" \\\n  --set openviking.config.storage.agfs.backend=\"s3\" \\\n  --set openviking.config.storage.agfs.s3.bucket=\"openvikingdata\" \\\n

openviking.config.storage.agfs.s3.endpoint=\"https://tos-s3-cn-beijing.volces.com\"\n```\n\n---\n\n## 4. 验证\n\n### 4.1 健康检查\n\n```bash\ncurl http://localhost:1933/health\n# 期望返回: {\"status\":\"ok\"}\n```\n\n### 4.2 就绪检查\n\n就绪接口会检测 AGFS（TOS）和 VikingDB 的连接状态，是验证凭据是否正确的关键步骤：\n\n```bash\ncurl http://localhost:1933/ready\n# 期望返回: {\"status\":\"ready\",\"checks\":{\"agfs\":\"ok\",\"vectordb\":\"ok\",\"api_key_manager\":\"ok\"}}\n```\n\n如果某个组件报错，请检查：\n\n| checks 字段 | 失败原因 | 排查方向 |\n|-------------|---------|---------|\n| `agfs` | TOS 连接失败 | 检查 bucket、endpoint、AK/SK 是否正确 |\n| `vectordb` | VikingDB 连接失败 | 检查 region、AK/SK、服务是否已开通 |\n| `api_key_manager` | root_api_key 未配置 | 检查 `server.root_api_key` 字段 |\n\n---\n\n## 5. 多租户管理\n\nOpenViking 支持多租户隔离。配置了 `root_api_key` 后自动启用多租户模式。\n\n### 5.1 创建租户（Account）\n\n使用 `root_api_key` 创建租户，同时会生成一个管理员用户：\n\n```bash\ncurl -X POST http://localhost:1933/api/v1/admin/accounts \\\n  -H \"X-API-Key: YOUR_ROOT_API_KEY\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\n    \"account_id\": \"my-team\",\n    \"admin_user_id\": \"admin\"\n  }'\n```\n\n返回结果中包含管理员的 API Key，**请妥善保存**：\n\n```json\n{\n  \"status\": \"ok\",\n  \"result\": {\n    \"account_id\": \"my-team\",\n    \"admin_user_id\": \"admin\",\n    \"user_key\": \"abcdef1234567890...\"\n  }\n}\n```\n\n### 5.2 注册普通用户\n\n租户管理员可以为租户添加用户：\n\n```bash\ncurl -X POST http://localhost:1933/api/v1/admin/accounts/my-team/users \\\n  -H \"X-API-Key: ADMIN_API_KEY\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\n    \"user_id\": \"alice\",\n    \"role\": \"user\"\n  }'\n```\n\n返回用户的 API Key：\n\n```json\n{\n  \"status\": \"ok\",\n  \"result\": {\n    \"user_id\": \"alice\",\n    \"user_key\": \"fedcba0987654321...\"\n  }\n}\n```\n\n### 5.3 查看租户下的用户\n\n```bash\ncurl http://localhost:1933/api/v1/admin/accounts/my-team/users \\\n  -H \"X-API-Key: ADMIN_API_KEY\"\n```\n\n---\n\n## 6. 运行示例\n\n`examples/cloud/` 目录下提供了完整的多租户 demo 脚本，演示从用户创建到数据使用的全流程。\n\n### 6.1 setup_users.py — 初始化租户和用户\n\n创建租户 `demo-team`，注册 alice（管理员）和 bob（普通用户），并将 API Key 写入 `user_keys.json` 供后续脚本使用。\n\n```bash\n# 确保 server 已启动，且 root_api_key 与 ov.conf 一致\nuv run examples/cloud/setup_users.py --url http://localhost:1933 --root-key <your-root-api-key>\n```\n\n### 6.2 alice.py — 技术负责人的使用流程\n\nAlice 演示：添加项目文档 → 语义搜索 → 多轮对话 → 沉淀记忆 → 回顾记忆。\n\n```bash\nuv run examples/cloud/alice.py\n```\n\n脚本会自动从 `user_keys.json` 读取 API Key。也可以手动指定：\n\n```bash\nuv run examples/cloud/alice.py --url http://localhost:1933 --api-key <alice_key>\n```\n\n### 6.3 bob.py — 新入职成员的使用流程\n\nBob 演示：浏览团队资源 → 回顾团队记忆（Alice 沉淀的决策） → 添加自己的资源 → 对话 → 沉淀记忆 → 带上下文搜索。\n\n建议在 alice.py 执行完毕后运行，这样 Bob 可以看到 Alice 沉淀的团队记忆：\n\n```bash\nuv run examples/cloud/bob.py\n```\n\n### 完整流程汇总\n\n```bash\n# 1. 启动服务（确保 ~/.openviking/ov.conf 已就位）\nopenviking-server &\n\n# 2. 等待服务就绪\ncurl http://localhost:1933/ready\n\n# 3. 创建用户\nuv run examples/cloud/setup_users.py --root-key <your-root-api-key>\n\n# 4. Alice: 添加文档 + 对话 + 沉淀记忆\nuv run examples/cloud/alice.py\n\n# 5. Bob: 浏览团队资源和记忆 + 入职学习\nuv run examples/cloud/bob.py\n```\n\n---\n\n## 7. 运维\n\n### 日志\n\n容器日志默认输出到 stdout，可通过 `docker logs` 或 K8s 日志系统查看：\n\n```bash\ndocker logs -f openviking\n```\n\n配置文件中 `log.level` 可调整日志级别（`DEBUG` / `INFO` / `WARN` / `ERROR`）。\n\n### 监控\n\n- 健康检查：`GET /health`\n- 就绪检查：`GET /ready`（检测 AGFS、VikingDB、APIKeyManager 连接状态）\n- 系统状态：`GET /api/v1/system/status`\n\n### 数据备份\n\n- **TOS 数据**：通过 TOS 控制台配置跨区域复制或定期备份\n- **本地数据**（如使用 PVC）：定期快照 PersistentVolume\n\n---\n\n## 8. 常见问题\n\n### systemd 启动失败（status=203/EXEC）\n\n`status=203/EXEC` 表示 systemd 找不到 `ExecStart` 指定的可执行文件。常见于使用 venv / conda 环境安装 OpenViking 的情况，`openviking-server` 不在 `/usr/local/bin/` 下。\n\n排查步骤：\n\n```bash\n# 1. 查找实际路径\nwhich openviking-server\n\n# 2. 将输出路径替换到 service 文件的 ExecStart\nsudo sed -i 's|ExecStart=.*|ExecStart=/实际/路径/openviking-server|' /etc/systemd/system/openviking.service\n\n# 3. 重新加载并启动\nsudo systemctl daemon-reload\nsudo systemctl restart openviking\nsudo systemctl status openviking\n```\n\n### docker: command not found\n\n系统未安装 Docker，请参考 [Docker 官方安装文档](https://docs.docker.com/engine/install/) 选择对应系统的安装方式。安装完成后启动 Docker：\n\n```bash\nsudo systemctl start docker\n```\n\n然后重新运行 `docker run` 命令即可。\n\n### TOS 连接失败（agfs check failed）\n\n- **endpoint 错误**：确认使用 S3 兼容 endpoint（带 `tos-s3-` 前缀），不要用标准 endpoint（`tos-cn-` 前缀）\n- **地域不匹配**：确认 `storage.agfs.s3.region` 和 `storage.agfs.s3.endpoint` 与桶所在地域一致\n- **bucket 不存在**：确认 TOS 控制台中桶已创建，且名称和地域与配置一致\n- **AK/SK 无权限**：确认 IAM 子用户拥有 `TOSFullAccess` 或对应桶的访问策略\n\n### VikingDB 鉴权失败（vectordb check failed）\n\n- **服务未开通**：在火山引擎控制台确认 VikingDB 已开通\n- **地域错误**：确认 `storage.vectordb.volcengine.region` 与开通服务的地域一致\n- **AK/SK 错误**：确认 `storage.vectordb.volcengine.ak/sk` 与 IAM 密钥一致\n- **权限不足**：确认 IAM 子用户拥有 `VikingDBFullAccess` 策略\n\n### Embedding 模型调用失败\n\n- **模型未开通**：在方舟控制台 **模型广场** 中确认 `doubao-embedding-vision-250615` 已申请并通过\n- **API Key 错误**：确认 `embedding.dense.api_key` 填写正确\n- **API Base 错误**：确认为 `https://ark.cn-beijing.volces.com/api/v3`\n\n### helm: command not found\n\n系统未安装 Helm，需要先安装：\n\n```bash\ncurl https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash\n```\n\n安装后验证：\n\n```bash\nhelm version\n```\n\n### Kubernetes cluster unreachable\n\n```\nError: INSTALLATION FAILED: Kubernetes cluster unreachable: Get \"http://localhost:8080/version\": dial tcp [::1]:8080: connect: connection refused\n```\n\n服务器上没有运行 Kubernetes 集群。可以使用 k3s 快速搭建轻量级集群：\n\n```bash\n# 安装 k3s\ncurl -sfL https://get.k3s.io | sh -\n\n# 配置 kubeconfig\nexport KUBECONFIG=/etc/rancher/k3s/k3s.yaml\n\n# 永久生效\necho 'export KUBECONFIG=/etc/rancher/k3s/k3s.yaml' >> ~/.bashrc\n\n# 验证集群就绪\nkubectl get nodes\n```\n\n看到节点状态为 `Ready` 后，再执行 `helm install` 命令。\n\n### helm install 时 path not found\n\n```\nError: INSTALLATION FAILED: path \"./examples/k8s-helm\" not found\n```\n\n需要在 OpenViking 项目根目录下执行 `helm install` 命令：\n\n```bash\ncd /path/to/OpenViking\nhelm install openviking ./examples/k8s-helm -f my-values.yaml\n```\n\n### Helm 安装后 Pod CrashLoopBackOff\n\n- 检查 `kubectl logs <pod-name>`，通常是配置字段缺失\n- 确认 values 文件中包含完整的 storage、embedding、vlm 配置（参考第 3 节 Helm 部分）\n- 确认 `openviking.config` 下的 JSON 结构正确（Helm 会将其序列化为 ov.conf）\n"

    "content": "# OpenViking Helm Chart\n\nThis Helm chart deploys OpenViking on Kubernetes, providing a scalable and production-ready RAG (Retrieval-Augmented Generation) and semantic search service.\n\n## Overview\n\n[OpenViking](https://github.com/volcengine/OpenViking) is an open-source RAG and semantic search engine that serves as a Context Database MCP (Model Context Protocol) server. This Helm chart enables easy deployment on Kubernetes clusters with support for major cloud providers.\n\n## Prerequisites\n\n- Kubernetes 1.24+\n- Helm 3.8+\n- A valid Volcengine API key for embedding and VLM services\n\n## Installation\n\n### Add the Helm repository (when published)\n\n```bash\nhelm repo add openviking https://volcengine.github.io/openviking\nhelm repo update\n```\n\n### Install from local chart\n\n```bash\n# Clone the repository\ngit clone https://github.com/volcengine/OpenViking.git\ncd OpenViking/deploy/helm\n\n# Install with default values\nhelm install openviking ./openviking\n\n# Install with custom values\nhelm install openviking ./openviking -f my-values.yaml\n```\n\n### Quick Start\n\n```bash\n# GCP deployment\nhelm install openviking ./openviking \\\n  --set cloudProvider=gcp \\\n  --set openviking.config.embedding.dense.api_key=YOUR_API_KEY\n\n# AWS deployment\nhelm install openviking ./openviking \\\n  --set cloudProvider=aws \\\n  --set openviking.config.embedding.dense.api_key=YOUR_API_KEY\n```\n\n## Configuration\n\n### Cloud Provider Support\n\nThe chart supports automatic LoadBalancer annotation configuration for major cloud providers:\n\n| Provider | Configuration Value |\n|----------|-------------------|\n| Google Cloud Platform | `cloudProvider: gcp` |\n| Amazon Web Services | `cloudProvider: aws` |\n| Other/Generic | `cloudProvider: \"\"` (default) |\n\n### Key Configuration Options\n\n| Parameter | Description | Default |\n|-----------|-------------|---------|\n| `cloudProvider` | Cloud provider for LoadBalancer annotations | `\"\"` |\n| `replicaCount` | Number of replicas | `1` |\n| `image.repository` | Container image repository | `ghcr.io/astral-sh/uv` |\n| `image.tag` | Container image tag | `python3.12-bookworm` |\n| `service.type` | Kubernetes service type | `LoadBalancer` |\n| `service.port` | Service port | `1933` |\n| `openviking.config.server.api_key` | API key for authentication | `null` |\n| `openviking.config.embedding.dense.api_key` | Volcengine API key | `null` |\n\n### OpenViking Configuration\n\nAll OpenViking configuration options from `ov.conf` are available under `openviking.config`. See `values.yaml` for the complete default configuration.\n\n### Embedding Configuration\n\nThe embedding service requires a Volcengine API key:\n\n```yaml\nopenviking:\n  config:\n    embedding:\n      dense:\n        api_key: \"your-api-key-here\"\n        api_base: \"https://ark.cn-beijing.volces.com/api/v3\"\n        model: \"doubao-embedding-vision-250615\"\n```\n\n### VLM Configuration\n\nFor vision-language model support:\n\n```yaml\nopenviking:\n  config:\n    vlm:\n      api_key: \"your-api-key-here\"\n      api_base: \"https://ark.cn-beijing.volces.com/api/v3\"\n      model: \"doubao-seed-2-0-pro-260215\"\n```\n\n## Storage\n\n### Default (emptyDir)\n\nBy default, the chart uses `emptyDir` volumes for data storage. This is suitable for development and testing but **data will be lost** when pods are restarted.\n\n### Persistent Storage (Optional)\n\nTo enable persistent storage with PVC:\n\n```yaml\nopenviking:\n  dataVolume:\n    enabled: true\n    usePVC: true\n    size: 50Gi\n    storageClassName: standard\n    accessModes:\n      - ReadWriteOnce\n```\n\n## Security\n\n### API Key Authentication\n\nEnable API key authentication to secure your OpenViking server:\n\n```yaml\nopenviking:\n  config:\n    server:\n      api_key: \"your-secure-api-key\"\n      cors_origins:\n        - \"https://your-domain.com\"\n```\n\n### Secrets Management\n\nFor production deployments, use Kubernetes secrets or external secret management:\n\n```bash\n# Create secret from literal\nkubectl create secret generic openviking-config \\\n  --from-literal=ov.conf='{\"server\":{\"api_key\":\"secret\"}}'\n\n# Or mount existing secret\nhelm install openviking ./openviking \\\n  --set existingSecret=openviking-config\n```\n\n## Autoscaling\n\nEnable Horizontal Pod Autoscaler for production workloads:\n\n```yaml\nautoscaling:\n  enabled: true\n  minReplicas: 2\n  maxReplicas: 10\n  targetCPUUtilizationPercentage: 80\n  targetMemoryUtilizationPercentage: 80\n```\n\n## Resource Limits\n\nDefault resource configuration:\n\n```yaml\nresources:\n  limits:\n    cpu: 2000m\n    memory: 4Gi\n  requests:\n    cpu: 500m\n    memory: 1Gi\n```\n\nAdjust based on your workload requirements.\n\n## Usage Examples\n\n### Connect with CLI\n\n```bash\n# Get the LoadBalancer IP\nexport OPENVIKING_IP=$(kubectl get svc openviking -o jsonpath='{.status.loadBalancer.ingress[0].ip}')\n\n# Create CLI configuration\ncat > ~/.openviking/ovcli.conf <<EOF\n{\n  \"url\": \"http://$OPENVIKING_IP:1933\",\n  \"api_key\": null,\n  \"output\": \"table\"\n}\nEOF\n\n# Test connection\nopenviking health\n```\n\n### Python Client\n\n```python\nimport openviking as ov\n\n# Get service endpoint\n# kubectl get svc openviking\n\nclient = ov.OpenViking(url=\"http://<load-balancer-ip>:1933\", api_key=\"your-key\")\nclient.initialize()\n\n# Add a resource\nclient.add_resource(path=\"./document.pdf\")\nclient.wait_processed()\n\n# Search\nresults = client.find(\"your search query\")\nprint(results)\n\nclient.close()\n```\n\n## Troubleshooting\n\n### Pod fails to start\n\nCheck the pod logs:\n```bash\nkubectl logs -l app.kubernetes.io/name=openviking\n```\n\n### Health check fails\n\nVerify the configuration:\n```bash\nkubectl get secret openviking-config -o jsonpath='{.data.ov\\.conf}' | base64 -d\n```\n\n### LoadBalancer not getting IP\n\nWait for the cloud provider to provision the load balancer:\n```bash\nkubectl get svc openviking -w\n```\n\nCheck cloud provider-specific annotations in `values.yaml`.\n\n## Uninstallation\n\n```bash\nhelm uninstall openviking\n```\n\nTo remove persistent data (if PVC was enabled):\n```bash\nkubectl delete pvc openviking-data\n```\n\n## Contributing\n\nContributions are welcome!

Health Check              无需认证，验证服务可用\n 2. Create Account            ROOT 创建 account \"acme\"，同时创建首个 admin \"alice\"\n 3. Register User (ROOT)      ROOT 在 \"acme\" 下注册普通用户 \"bob\"\n 4. Register User (ADMIN)     alice (ADMIN) 在 \"acme\" 下注册用户 \"charlie\"\n 5. List Accounts             ROOT 列出所有 account\n 6. List Users                列出 \"acme\" 下所有用户及角色\n 7. Change Role               ROOT 将 bob 提升为 ADMIN\n 8. Regenerate Key            为 charlie 重新生成 key，旧 key 立即失效\n 9. Access Data               bob 使用 user key 访问数据\n10. Error Tests               非法 key、权限不足、重复创建、旧 key 等负面用例\n11. Remove User               删除 charlie，验证其 key 失效\n12. Delete Account            删除 account \"acme\"，验证 alice 的 key 也失效\n```\n\n## CLI 命令参考\n\n```bash\n# Account 管理\nopenviking admin create-account <account_id> --admin <admin_user_id>\nopenviking admin list-accounts\nopenviking admin delete-account <account_id>\n\n# User 管理\nopenviking admin register-user <account_id> <user_id> [--role user|admin]\nopenviking admin list-users <account_id>\nopenviking admin remove-user <account_id> <user_id>\nopenviking admin set-role <account_id> <user_id> <role>\nopenviking admin regenerate-key <account_id> <user_id>\n```\n\n## 文件说明\n\n```\nadmin_workflow.py    Python SDK 示例（httpx 调用 Admin API + SyncHTTPClient 访问数据）\nadmin_workflow.sh    CLI 示例（openviking admin 命令，同等流程）\nov.conf.example      Server 配置文件模板（含 root_api_key）\npyproject.toml       项目依赖\nREADME.md            本文件\n```\n\n## Admin API 参考\n\n| 方法 | 端点 | 所需角色 | 说明 |\n|------|------|---------|------|\n| POST | `/api/v1/admin/accounts` | ROOT | 创建 account + 首个 admin |\n| GET | `/api/v1/admin/accounts` | ROOT | 列出所有 account |\n| DELETE | `/api/v1/admin/accounts/{id}` | ROOT | 删除 account |\n| POST | `/api/v1/admin/accounts/{id}/users` | ROOT, ADMIN | 注册用户 |\n| GET | `/api/v1/admin/accounts/{id}/users` | ROOT, ADMIN | 列出用户 |\n| DELETE | `/api/v1/admin/accounts/{id}/users/{uid}` | ROOT, ADMIN | 移除用户 |\n| PUT | `/api/v1/admin/accounts/{id}/users/{uid}/role` | ROOT | 修改用户角色 |\n| POST | `/api/v1/admin/accounts/{id}/users/{uid}/key` | ROOT, ADMIN | 重新生成 user key |\n\n## 相关文档\n\n- [认证指南](../../docs/zh/guides/04-authentication.md) - 完整认证说明\n- [配置指南](../../docs/zh/guides/01-configuration.md) - 配置文件参考\n- [API 概览](../../docs/zh/api/01-overview.md) - 完整 API 参考\n- [Server-Client 示例](../server_client/) - 基础 Server/Client 用法\n"

Pass the chosen directory via `--workdir`:\n\n```bash\nnpx ./examples/openclaw-plugin/setup-helper --workdir ~/.openclaw-openclaw-second\n```\n\nIf only `~/.openclaw` exists, proceed with the default.\n\n## Step 1: Choose Deployment Mode\n\nAsk the user: \"How do you want to use OpenViking?\"\n\n- **A) Local** — Run OpenViking on this machine (requires Python >= 3.10)\n- **B) Remote** — Connect to an existing OpenViking server (only needs the server URL and API Key)\n\n→ A: Go to [Local Deployment Path](#local-deployment-path)\n→ B: Go to [Remote Connection Path](#remote-connection-path)\n\n---\n\n## Local Deployment Path\n\n### Step L1: Check Environment\n\nRun each check. Every check must pass before continuing.\n\n**1. Python**\n\n```bash\npython3 --version\n```\n\n- Pass: >= 3.10\n- Fail: Tell user \"Python >= 3.10 is required. Install from https://www.python.org/downloads/\"\n- Multiple versions: Ask user which Python path to use\n\n**2. Node.js**\n\n```bash\nnode -v\n```\n\n- Pass: >= v22\n- Fail: Tell user \"Node.js >= 22 is required. Install from https://nodejs.org/\"\n\n**3. OpenClaw**\n\n```bash\nopenclaw --version\n```\n\n- Pass: Version output present\n- Fail: Tell user to run `npm install -g openclaw && openclaw onboard`\n\n### Step L2: Install OpenViking\n\n```bash\npython3 -m pip install openviking --upgrade\n```\n\n- Pass: Continue\n- Fail with `externally-managed`:\n  ```bash\n  python3 -m venv ~/.openviking/venv\n  ~/.openviking/venv/bin/pip install openviking --upgrade\n  ```\n  Set `OPENVIKING_PYTHON=~/.openviking/venv/bin/python` for later steps\n- Fail with `No matching distribution`: Python is below 3.10, tell user to upgrade\n- Other failure: Print full error, ask user\n\nVerify:\n\n```bash\npython3 -c \"import openviking; print('ok')\"\n```\n\n### Step L3: Configure\n\nCheck if `~/.openviking/ov.conf` already exists:\n\n- **Exists**: Ask user \"Found existing config at ~/.openviking/ov.conf. Keep it?\"\n  - Yes: Skip to Step L4\n  - No: Continue with configuration below\n\n- **Does not exist**: Collect configuration\n\n**Ask user for API Key:**\n\n> \"Please provide your Volcengine Ark API Key (used for Embedding and VLM model calls).\n> Get one at https://console.volcengine.com/ark if you don't have one.\"\n\nRun the setup helper:\n\n```bash\nnpm install -g openclaw-openviking-setup-helper\nov-install\n```\n\nAt the interactive prompts:\n- Workspace: Press Enter for default path\n- API Key: Enter the user's key\n- VLM model: Press Enter for default `doubao-seed-2-0-pro-260215`\n- Embedding model: Press Enter for default `doubao-embedding-vision-251215`\n- Ports: Press Enter for default 1933/1833\n\nWait for `Setup complete!`\n\n### Step L4: Start and Verify\n\n```bash\nsource ~/.openclaw/openviking.env && openclaw gateway\n```\n\n- Pass: Output contains `openviking: local server started`\n- Fail with `port occupied`:\n  The port is used by another process. Change port:\n  ```bash\n  openclaw config set plugins.entries.openviking.config.port 1934\n  source ~/.openclaw/openviking.env && openclaw gateway\n  ```\n- Fail with `subprocess exited`: Check stderr for Python errors — usually wrong API Key or openviking not installed properly\n\nVerify:\n\n```bash\nopenclaw status\n```\n\nContextEngine line should show `enabled (plugin openviking)`.\n\nTell user: \"OpenViking memory is active. I'll automatically remember important facts from our conversations and recall them when relevant.\"\n\n---\n\n## Remote Connection Path\n\n### Step R1: Collect Connection Info\n\nAsk user for:\n\n1. **OpenViking server URL** (e.g. `http://10.0.0.1:1933`)\n   > This is the OpenViking HTTP API address.\n\n2. **OpenViking API Key** (optional)\n   > Required if the server has `root_api_key` configured. This authenticates to the OpenViking server — it is NOT a Volcengine Ark API Key.\n\n### Step R2: Check Environment\n\n**1. Node.js**\n\n```bash\nnode -v\n```\n\n- Pass: >= v22\n- Fail: Tell user to install Node.js >= 22\n\n**2. OpenClaw**\n\n```bash\nopenclaw --version\n```\n\n- Pass: Version output present\n- Fail: `npm install -g openclaw && openclaw onboard`\n\n> Remote mode does **not** require Python — OpenViking runs on the remote server.\n\n### Step R3: Install Plugin and Configure\n\n```bash\nnpm install -g openclaw-openviking-setup-helper\nov-install\n# Select remote mode, enter OpenViking server URL and API Key\n```\n\nAlternatively, configure manually (substitute user-provided values). If targeting a non-default instance, prefix each command with `OPENCLAW_STATE_DIR=<workdir>`:\n\n```bash\nopenclaw config set plugins.enabled true --json\nopenclaw config set plugins.slots.contextEngine openviking\nopenclaw config set plugins.entries.openviking.config.mode remote\nopenclaw config set plugins.entries.openviking.config.baseUrl \"<user's server URL>\"\nopenclaw config set plugins.entries.openviking.config.apiKey \"<user's API Key>\"\nopenclaw config set plugins.entries.openviking.config.autoRecall true --json\nopenclaw config set plugins.entries.openviking.config.autoCapture true --json\n```\n\nIf user has no API Key (server auth not enabled), skip the apiKey line.\n\n### Step R4: Start and Verify\n\n```bash\nopenclaw gateway\n```\n\n- Pass: Output contains `openviking: initialized`\n- Fail with connection error: Verify server is reachable — `curl <baseUrl>/health` should return `{\"status\":\"ok\"}`\n\n```bash\nopenclaw status\n```\n\nContextEngine line should show `enabled (plugin openviking)`.\n\nTell user: \"OpenViking memory is connected to the remote server. I'll automatically remember important facts and recall them when relevant.\"\n\n---\n\n## Field Reference\n\n| Field | Meaning | Required For |\n|-------|---------|-------------|\n| Volcengine Ark API Key | Embedding + VLM model access | Local |\n| OpenViking API Key | Server authentication key | Remote (if server has auth enabled) |\n| agentId | Identifies this agent to OpenViking | Both (auto-generated if not set) |\n| baseUrl | OpenViking HTTP address | Remote |\n| workspace | Data storage directory | Local |\n| server port | OpenViking HTTP port (default 1933) | Local |\n| VLM model | Memory extraction model | Local |\n| Embedding model | Text vectorization model | Local |\n\n---\n\n## Troubleshooting\n\n| Error | Cause | Fix |\n|-------|-------|-----|\n| `port occupied` | Port used by another process | Change port in config, e.g. `openclaw config set plugins.entries.openviking.config.port 1934` |\n| `extracted 0 memories` | Wrong API Key or model name | Check `api_key` and `model` in `~/.openviking/ov.conf` |\n| `externally-managed-environment` | Python PEP 668 restriction | Install via venv |\n| `ECONNREFUSED` | Remote server unreachable | Verify baseUrl and network connectivity |\n| Plugin not loaded | Env file not sourced | `source ~/.openclaw/openviking.env` (local mode) |\n"

    "content": "# 为 OpenClaw 安装 OpenViking 记忆功能\n\n通过 [OpenViking](https://github.com/volcengine/OpenViking) 为 [OpenClaw](https://github.com/openclaw/openclaw) 提供长效记忆能力。安装完成后，OpenClaw 将自动**记住**对话中的重要信息，并在回复前**回忆**相关内容。OpenViking 最新版本发布了 [WebConsole](https://github.com/volcengine/OpenViking/tree/main/openviking/console)，方便调试和运维。文档方式三也提供了如何在 WebConsole 界面验证记忆写入的说明，欢迎试用和反馈。\n\n> **ℹ️ 历史兼容性说明**\n>\n> 旧版 OpenViking/OpenClaw 集成方案在 OpenClaw `2026.3.12` 附近曾出现过已知兼容性问题，表现为加载插件后对话卡死无响应。\n> 该问题主要影响旧版本插件链路；当前文档介绍的 context-engine 插件 2.0 已不再受此问题影响，新的安装流程无需因此回退 OpenClaw。\n> 同时，插件 2.0 与旧版 `memory-openviking` 插件及其配置不兼容，升级时需要按本文迁移步骤完成替换，不能混装。\n> 插件 2.0 也依赖 OpenClaw 的 context-engine 能力，不支持旧版 OpenClaw；请升级到当前安装助手支持的较新 OpenClaw 版本后再安装。\n> 如需排查旧版本部署，可参考 [#591](https://github.com/volcengine/OpenViking/issues/591) 以及上游修复 PR：openclaw/openclaw#34673、openclaw/openclaw#33547。\n\n> **🚀 插件 2.0（context-engine 架构）**\n>\n> 当前文档介绍的是基于 context-engine 架构的 OpenViking 插件 2.0 方案，也是 OpenViking 接入 AI 编程助手的推荐实践。\n> 更多背景和演进讨论可见：https://github.com/volcengine/OpenViking/discussions/525\n\n---\n\n## 一键安装\n\n该安装方式支持您从 安装 - 验证 - 读取 - 写入 - 查看 一站式了解OpenViking。 \n\n**前置条件：** Python >= 3.10，Node.js >= 22。安装助手会自动检查并提示安装缺少的组件。\n\n### 从旧版 `memory-openviking` 升级到新版 `openviking` 前置操作步骤\n\n- 如果当前环境里已经安装过旧版插件 `memory-openviking`，建议先完成以下前置操作，再执行新版安装。\n\n- 如果您之前没有安装过，可以跳过此步骤，直接查看 **“正式安装”** 环节。\n\n- 插件 2.0 与旧版插件/旧版配置不兼容，需避免旧版和新版插件同时存在。\n\n1. 停止 OpenClaw gateway：\n\n```bash\nopenclaw gateway stop\n```\n\n2. 备份旧版本配置和插件目录：\n\n```bash\ncp ~/.openclaw/openclaw.json ~/.openclaw/openclaw.json.pre-openviking-upgrade.bak\nmkdir -p ~/.openclaw/disabled-extensions\nmv ~/.openclaw/extensions/memory-openviking ~/.openclaw/disabled-extensions/memory-openviking-upgrade-backup\n```\n\n3. 修改 OpenClaw 配置，移除旧版本配置参数：\n\n编辑 `~/.openclaw/openclaw.json`，删除 `plugins.allow` 中的 `\"memory-openviking\"`，删除 `plugins.entries.memory-openviking`，并将 `plugins.slots.memory` 改为 `\"none\"`，将 `plugins.load.paths`中旧版本 `memory-openviking` 插件路径修改为`openviking`。\n\n4. 参考下面方式A或者安装方式B的操作步骤，安装新版插件\n\n5. 保留并迁移旧版本运行参数到新版本配置（新版本默认可用，旧版本参数按需迁移）：\n\n如果旧版本原来使用的是 `plugins.entries.memory-openviking.config`，请将第二步备份的openclaw配置文件中的 `mode`、`configPath`、`port`、`baseUrl`、`apiKey`、`agentId` 等参数按需迁移到新版 `plugins.entries.openviking.config`。\n\n前置步骤根据您的个人情况按需执行，完成以后，即可进入2.0的安装环节，在此我们暂时不建议直接自然语言安装，推荐使用 npm 一键安装。\n\n### 正式安装\n\n#### 方式 A：npm 安装（推荐，全平台）\n\n```bash\nnpm install -g openclaw-openviking-setup-helper\nov-install\n```\n\n非交互模式（使用默认配置）：\n\n```bash\nov-install -y\n```\n\n安装到指定 OpenClaw 实例：\n\n```bash\nov-install --workdir ~/.openclaw-second\n```\n备注：在运行 `npm install -g openclaw-openviking-setup-helper` 命令时，可能会出现没有安装创建虚拟环境的工具的报错提示，可以直接复制报错提示中的解决方案执行：\n\n```bash\napt update\napt install -y software-properties-common\nadd-apt-repository universe\napt update\napt install -y python3-venv\n```\n运行完上面这几行命令后，再次执行你的安装命令：\n\n```bash\nov-install\n```\n\n这次脚本就能成功创建一个隔离的虚拟环境，并顺利把 OpenViking 安装进去了，而且不会破坏你的系统环境。\n\n出现`installation completed`即代表安装成功。\n\n#### 方式 B（可选）：curl 一键安装（Linux / macOS）\n\n```bash\ncurl -fsSL https://raw.githubusercontent.com/volcengine/OpenViking/main/examples/openclaw-plugin/install.sh | bash\n```\n\n非交互模式：\n\n```bash\ncurl -fsSL https://raw.githubusercontent.com/volcengine/OpenViking/main/examples/openclaw-plugin/install.sh | bash -s -y\n```\n\n安装到指定 OpenClaw 实例：\n\n```bash\ncurl -fsSL ... | bash -s -- --workdir ~/.openclaw-openclaw-second\n```\n\n脚本会自动检测多个 OpenClaw 实例并让你选择。还会提示选择 local/remote 模式——remote 模式连接远端 OpenViking 服务，不需要安装 Python。\n\n出现`installation completed`即代表安装成功。\n\n### 启动OpenClaw + OpenViking\n\n安装成功以后，运行以下命令启动 OpenClaw + OpenViking\n\n```bash\nsource ~/.openclaw/openviking.env && openclaw gateway restart\n```\n出现 `openviking: registered context-engine` 代表拉取成功。\n\n接着，执行\n\n```bash\nopenclaw config get plugins.slots.contextEngine\n```\n\n出现 `openviking`，则验证启动成功。\n\n### 验证读取和写入\n\n现在可以自由和 OpenClaw 进行交互和对话，过程中，你可以通过以下命令查看 OpenViking 运行状态，验证读取和写入：\n\n验证读取：`cat 填入您的日志文件路径（如：/tmp/openclaw/openclaw-2026-03-20.log） |grep auto-capture`\n\n验证写入：`cat 填入您的日志文件路径（如：/tmp/openclaw/openclaw-2026-03-20.log） |grep inject`\n\nOpenClaw日志查看：`openclaw logs --follow`，出现 `openviking: auto-captured 2 new messages, extracted 1 memories` 说明状态正常\n\n### 通过 ov tui 查看您的记忆文件\n\n我们提供了命令行查看 OpenViking 中虚拟文件的方式，首先 `cd` 到您的 OpenViking 目录，`source venv/bin/activate`激活虚拟环境\n\n输入 `ov --help`了解 OpenViking 具体命令，输入 `ov tui`即可进入文件界面，按`.`可打开文件夹，支持方向键上下查看文件，按`q`退出。\n\n---\n\n## 前置条件\n\n| 组件 | 版本要求 | 用途 |\n|------|----------|------|\n| **Python** | >= 3.10 | OpenViking 运行时 |\n| **Node.js** | >= 22 | OpenClaw 运行时 |\n| **火山引擎 Ark API Key** | — | Embedding + VLM 模型调用 |\n\n快速检查：\n\n```bash\npython3 --version   # >= 3.10\nnode -v              # >= v22\nopenclaw --version   # 已安装\n```\n\n- Python: https://www.python.org/downloads/\n- Node.js: https://nodejs.org/\n- OpenClaw: `npm install -g openclaw && openclaw onboard`\n\n---\n\n## 方式一：本地部署（推荐）\n\n在本机启动 OpenViking 服务，适合个人使用。\n\n### Step 1: 安装 OpenViking\n\n```bash\npython3 -m pip install openviking --upgrade\n```\n\n验证：`python3 -c \"import openviking; print('ok')\"`\n\n> 遇到 `externally-managed-environment`？使用一键安装脚本（自动处理 venv）或手动创建：\n> `python3 -m venv ~/.openviking/venv && ~/.openviking/venv/bin/pip install openviking`\n\n### Step 2: 运行安装助手\n\n```bash\n# 方式 A：npm 安装（推荐，全平台）\nnpm install -g openclaw-openviking-setup-helper\nov-install\n\n# 方式 B：curl 一键安装（Linux / macOS）\ncurl -fsSL https://raw.githubusercontent.com/volcengine/OpenViking/main/examples/openclaw-plugin/install.sh | bash\n```\n\n安装助手会提示输入 Ark API Key 并自动生成配置文件。\n\n### Step 3: 启动\n\n```bash\nsource ~/.openclaw/openviking.env && openclaw gateway\n```\n\n看到 `openviking: local server started` 表示成功。\n\n### Step 4: 验证\n\n```bash\nopenclaw status\n# Memory 行应显示：enabled (plugin openviking)\n```\n\n---\n\n## 方式二：连接远端 OpenViking\n\n已有运行中的 OpenViking 服务？只需配置 OpenClaw 插件指向远端，**不需要安装 Python / OpenViking**。\n\n**前置：** 已有 OpenViking 服务地址 + API Key（如服务端启用了认证）。\n\n### Step 1: 安装插件\n\n```bash\nnpm install -g openclaw-openviking-setup-helper\nov-install\n# 选择 remote 模式，填入 OpenViking 服务地址和 API Key\n```\n\n### Step 2: 启动并验证\n\n```bash\nopenclaw gateway restart\nopenclaw status\n```\n\n<details>\n<summary>手动配置（不使用安装助手）</summary>\n\n```bash\nopenclaw config set plugins.enabled true --json\nopenclaw config set plugins.slots.contextEngine openviking\nopenclaw config set plugins.entries.openviking.config.mode remote\nopenclaw config set plugins.entries.openviking.config.baseUrl \"http://your-server:1933\"\nopenclaw config set plugins.entries.openviking.config.apiKey \"your-api-key\"\nopenclaw config set plugins.entries.openviking.config.agentId \"your-agent-id\"\nopenclaw config set plugins.entries.openviking.config.autoRecall true --json\nopenclaw config set plugins.entries.openviking.config.autoCapture true --json\n```\n\n</details>\n\n## 方式三 火山引擎 ECS 版 Openclaw 接入 OpenViking\n\n本部分主要介绍如何在火山引擎ECS上接入OpenViking，并使用WebConsole验证写入。详情可见[文档](https://www.volcengine.com/docs/6396/2249500?lang=zh)。\n\n需注意 ECS 实例为了保护系统 Python 不被弄坏，在根目录（root）部署会有限制，不能直接用 pip 装全局包，推荐先创建虚拟环境，在虚拟环境下完成以下操作步骤。\n\n**前置：** 已有 ECS OpenClaw实例。\n\n### Step 1: npm 安装\n\n```python\nnpm install -g openclaw-openviking-setup-helper\nov-install\n```\n本安装模式已经在OpenViking内置了vlm和embedding模型，若不需要修改，直接按回车，按照指引填入API key即可. 安装完成后，会自动生成配置文件，如需修改，输入 vim ~/.openviking/ov.conf，按 i 进入编辑模式，按 esc 键退出编辑模式，输入 :wq 按回车键，保存并退出文件。\n\n终端加载 OpenClaw 环境变量：\n\n```bash\nsource /root/.openclaw/openviking.env\n```\n### Step 2: 启动OpenViking\n\n先启动 OpenViking Server：\n\n```python\npython -m openviking.server.bootstrap\n```\n然后启动 web 控制台，启动之前，需要确认本实例安全组是否已经在入向规则处开放 TCP 8020 端口，若没有，需先点击实例安全组配置：\n\n```python\npython -m openviking.console.bootstrap --host 0.0.0.0 --port 8020 --openviking-url http://127.0.0.1:1933\n```\n在实例中，找到你的服务器公网IP，用你的服务器公网IP访问: http://你的服务器公网IP:8020\n\n即可开始体验 web console 🎉\n\n你可以直接在web界面查询文件信息，验证OpenViking memory-plugin记忆写入是否生效；也可以可以在OpenClaw日志中验证openviking是否读取记忆，验证方式：\n\n\n```bash\ngrep -i inject /tmp/openclaw/openclaw-2026-03-13.log | awk -F'\"' '{for(i=1;i<=NF;i++) if($i ~ /^[0-9]{2}:[0-9]{2}:[0-9]{2}/) {time=$i; break}} /injecting [0-9]+ memories/ {print time, \"openviking:\", gensub(/.*(injecting [0-9]+ memories).*/, \"\\\\1\", \"1\")}'\n```\n\n也可以直接运行grep \"inject\" /tmp/openclaw/openclaw-2026-03-13.log查看全部信息。\n\n\n---\n\n## 配置参考\n\n### `~/.openviking/ov.conf`（本地模式）\n\n```json\n{\n  \"root_api_key\": null,\n  \"server\": { \"host\": \"127.0.0.1\", \"port\": 1933 },\n  \"storage\": {\n    \"workspace\": \"/home/yourname/.openviking/data\",\n    \"vectordb\": { \"backend\": \"local\" },\n    \"agfs\": { \"backend\": \"local\", \"port\": 1833 }\n  },\n  \"embedding\": {\n    \"dense\": {\n      \"provider\": \"volcengine\",\n      \"api_key\": \"<your-ark-api-key>\",\n      \"model\": \"doubao-embedding-vision-251215\",\n      \"api_base\": \"https://ark.cn-beijing.volces.com/api/v3\",\n      \"dimension\": 1024,\n      \"input\": \"multimodal\"\n    }\n  },\n  \"vlm\": {\n    \"provider\": \"volcengine\",\n    \"api_key\": \"<your-ark-api-key>\",\n    \"model\": \"doubao-seed-2-0-pro-260215\",\n    \"api_base\": \"https://ark.cn-beijing.volces.com/api/v3\"\n  }\n}\n```\n\n> `root_api_key`：设置后，所有 HTTP 请求须携带 `X-API-Key` 头。本地模式默认为 `null`（不启用认证）。\n\n### `agentId` 配置（插件配置）\n\n通过 `X-OpenViking-Agent` header 传给服务端的 Agent 标识，用于区分不同的 OpenClaw 实例。\n\n自定义方式：\n\n```bash\n# 在插件配置中指定\nopenclaw config set plugins.entries.openviking.config.agentId \"my-agent\"\n```\n\n如果未配置，插件会自动生成一个随机唯一的 ID（格式：`openclaw-<hostname>-<random>`）。\n\n### `~/.openclaw/openviking.env`\n\n由安装助手自动生成，记录 Python 路径等环境变量：\n\n```bash\nexport OPENVIKING_PYTHON='/usr/local/bin/python3'\n```\n\n---\n\n## 日常使用\n\n```bash\n# 启动\nsource ~/.openclaw/openviking.env && openclaw gateway\n\n# 检查当前 context-engine\nopenclaw status\nopenclaw config get plugins.slots.contextEngine\n\n# 关闭记忆\nopenclaw config set plugins.slots.contextEngine legacy\n\n# 开启记忆\nopenclaw config set plugins.slots.contextEngine openviking\n```\n\n---\n\n## 常见问题\n\n| 症状 | 原因 | 修复 |\n|------|------|------|\n| `port occupied` | 端口被其他进程占用 | 换端口：`openclaw config set plugins.entries.openviking.config.port 1934` |\n| `extracted 0 memories` | API Key 或模型名配置错误 | 检查 `ov.conf` 中 `api_key` 和 `model` 字段 |\n| 插件未加载 | 未加载环境变量 | 启动前执行 `source ~/.openclaw/openviking.env` |\n| `externally-managed-environment` | Python PEP 668 限制 | 使用 venv 或一键安装脚本 |\n| `TypeError: unsupported operand type(s) for \\|` | Python < 3.10 | 升级 Python 至 3.10+ |\n\n---\n\n## 卸载\n\n```bash\nlsof -ti tcp:1933 tcp:1833 tcp:18789 | xargs kill -9\nnpm uninstall -g openclaw && rm -rf ~/.openclaw\npython3 -m pip uninstall openviking -y && rm -rf ~/.openviking\n```\n\n---\n\n**另见：** [INSTALL.md](./INSTALL.md)（English） ·

    "content": "# Installing OpenViking for OpenClaw\n\nProvide long-term memory capabilities for [OpenClaw](https://github.com/openclaw/openclaw) via [OpenViking](https://github.com/volcengine/OpenViking). After installing, OpenClaw will automatically **remember** important information from conversations and **recall** relevant content before replying. The latest version of OpenViking includes a [WebConsole](https://github.com/volcengine/OpenViking/tree/main/openviking/console) for debugging and operations. Method 3 in this document also provides instructions on how to verify that memories are written via the WebConsole interface. We welcome you to try it out and provide feedback.\n\n> **ℹ️ Historical Compatibility Note**\n>\n> Legacy OpenViking/OpenClaw integrations had a known issue around OpenClaw `2026.3.12` where conversations could hang after the plugin loaded.\n> That issue affected the legacy plugin path; the current context-engine Plugin 2.0 described in this document is not affected, so new installations do not need to downgrade OpenClaw for this reason.\n> Plugin 2.0 is also not backward-compatible with the legacy `memory-openviking` plugin and its configuration, so upgrades must replace the old setup instead of mixing the two versions.\n> Plugin 2.0 also depends on OpenClaw's context-engine capability and does not support older OpenClaw releases; upgrade OpenClaw first before following this guide.\n> If you are troubleshooting a legacy deployment, see [#591](https://github.com/volcengine/OpenViking/issues/591) and upstream fix PRs: openclaw/openclaw#34673, openclaw/openclaw#33547.\n\n> **🚀 Plugin 2.0 (Context-Engine Architecture)**\n>\n> This document covers the current OpenViking Plugin 2.0 built on the context-engine architecture, which is the recommended integration path for AI coding assistants.\n> For design background and earlier discussion, see:\n> https://github.com/volcengine/OpenViking/discussions/525\n\n---\n\n## One-Click Installation\n\n**Prerequisites:** Python >= 3.10, Node.js >= 22. The setup helper will automatically check and prompt you to install any missing components.\n\n### Prerequisite Steps for Upgrading from Legacy `memory-openviking` to New `openviking`\n\nIf the current environment already has the legacy `memory-openviking` plugin installed, complete the following prerequisite steps before installing the new version. Plugin 2.0 is not backward-compatible with the legacy plugin/configuration, so do not keep both versions active at the same time.\n\n1. Stop the OpenClaw gateway:\n\n```bash\nopenclaw gateway stop\n```\n\n2. Back up the legacy configuration and plugin directory:\n\n```bash\ncp ~/.openclaw/openclaw.json ~/.openclaw/openclaw.json.pre-openviking-upgrade.bak\nmkdir -p ~/.openclaw/disabled-extensions\nmv ~/.openclaw/extensions/memory-openviking ~/.openclaw/disabled-extensions/memory-openviking-upgrade-backup\n```\n\n3. Update the OpenClaw configuration and remove legacy settings:\n\nEdit `~/.openclaw/openclaw.json`, remove `\"memory-openviking\"` from `plugins.allow`, remove `plugins.entries.memory-openviking`, change `plugins.slots.memory` to `\"none\"`, and remove the legacy `memory-openviking` plugin path from `plugins.load.paths`.\n\n4. Install the new plugin by following Method A or Method B below.\n\n5. Preserve and migrate legacy runtime settings into the new configuration if needed (the new version works with defaults; legacy parameters are optional to migrate):\n\nIf the legacy plugin was using `plugins.entries.memory-openviking.config`, migrate `mode`, `configPath`, `port`, `baseUrl`, `apiKey`, `agentId`, and any other needed parameters from the backup `openclaw.json` file created in Step 2 into `plugins.entries.openviking.config`.\n\n### Method A: npm Installation (Recommended, Cross-platform)\n\n```bash\nnpm install -g openclaw-openviking-setup-helper\nov-install\n\n```\n\nIf the installation fails because the system is missing tools to create a virtual environment, operate these commands below and re-run `ov-install`:\n\n```bash\napt update\napt install -y software-properties-common\nadd-apt-repository universe\napt update\napt install -y python3-venv\n```\n\nNon-interactive mode (uses default configuration):\n\n```bash\nov-install -y\n\n```\n\nInstall to a specific OpenClaw instance:\n\n```bash\nov-install --workdir ~/.openclaw-second\n\n```\n\n### Method B: curl One-Click Installation (Linux / macOS)\n\n```bash\ncurl -fsSL https://raw.githubusercontent.com/volcengine/OpenViking/main/examples/openclaw-plugin/install.sh | bash\n\n```\n\nNon-interactive mode:\n\n```bash\ncurl -fsSL https://raw.githubusercontent.com/volcengine/OpenViking/main/examples/openclaw-plugin/install.sh | bash -s -y\n\n```\n\nInstall to a specific OpenClaw instance:\n\n```bash\ncurl -fsSL ... | bash -s -- --workdir ~/.openclaw-openclaw-second\n\n```\n\nThe script will automatically detect multiple OpenClaw instances and let you choose. It will also prompt you to select local/remote mode—remote mode connects to a remote OpenViking service and does not require installing Python.\n\n### Start OpenClaw + OpenViking\n\n```bash\nsource ~/.openclaw/openviking.env && openclaw gateway restart\n```\n\nSeeing `openviking: registered context-engine` indicates the plugin was loaded.\n\nThen verify:\n\n```bash\nopenclaw config get plugins.slots.contextEngine\n```\n\nIf it shows `openviking`, the startup is successful.\n\n### Verify Read and Write\n\nUse OpenClaw logs to verify memory capture and recall:\n\n```bash\nopenclaw logs --follow\n```\n\nLook for:\n\n```\nopenviking: auto-captured 2 new messages, extracted 1 memories\n```\n\nYou can also check a specific log file:\n\n```bash\ncat <your-log-file> | grep auto-capture\ncat <your-log-file> | grep inject\n```\n\nExample:\n\n```bash\ncat /tmp/openclaw/openclaw-2026-03-20.log | grep auto-capture\ncat /tmp/openclaw/openclaw-2026-03-20.log | grep inject\n```\n\n### View Memories with `ov tui`\n\nIn your OpenViking directory, activate the virtual environment and open the TUI:\n\n```bash\nsource venv/bin/activate\nov --help\nov tui\n```\n\nPress `.` to expand folders, use arrow keys to navigate, and press `q` to quit.\n\n---\n\n## Prerequisites\n\n| Component | Version Requirement | Purpose |\n| --- | --- | --- |\n| **Python** | >= 3.10 | OpenViking Runtime |\n| **Node.js** | >= 22 | OpenClaw Runtime |\n| **Volcengine Ark API Key** | — | Embedding + VLM model calls |\n\nQuick check:\n\n```bash\npython3 --version   # >= 3.10\nnode -v              # >= v22\nopenclaw --version   # Installed\n\n```\n\n* Python: [https://www.python.org/downloads/](https://www.python.org/downloads/)\n* Node.js: [https://nodejs.org/](https://nodejs.org/)\n* OpenClaw: `npm install -g openclaw && openclaw onboard`\n\n---\n\n## Method 1: Local Deployment (Recommended)\n\nStart the OpenViking service locally, suitable for personal use.\n\n### Step 1: Install OpenViking\n\n```bash\npython3 -m pip install openviking --upgrade\n\n```\n\nVerification: `python3 -c \"import openviking; print('ok')\"`\n\n> Encountered `externally-managed-environment`? Use the one-click installation script (which handles venv automatically) or create it manually:\n> `python3 -m venv ~/.openviking/venv && ~/.openviking/venv/bin/pip install openviking`\n\n### Step 2: Run the Setup Helper\n\n```bash\n# Method A: npm install (recommended, cross-platform)\nnpm install -g openclaw-openviking-setup-helper\nov-install\n\n# Method B: curl one-click (Linux / macOS)\ncurl -fsSL https://raw.githubusercontent.com/volcengine/OpenViking/main/examples/openclaw-plugin/install.sh | bash\n```\n\nThe setup helper will prompt you to enter your Ark API Key and automatically generate a configuration file.\n\n### Step 3: Start\n\n```bash\nsource ~/.openclaw/openviking.env && openclaw gateway\n\n```\n\nSeeing `openviking: local server started` indicates success.\n\n### Step 4: Verify\n\n```bash\nopenclaw status\n# The ContextEngine row should display: enabled (plugin openviking)\n\n```\n\n---\n\n## Method 2: Connecting to Remote OpenViking\n\nAlready have a running OpenViking service? Simply configure the OpenClaw plugin to point to the remote address; **no Python / OpenViking installation is required**.\n\n**Prerequisites:** An existing OpenViking service address + API Key (if authentication is enabled on the server side).\n\n### Step 1: Install Plugin\n\n```bash\nnpm install -g openclaw-openviking-setup-helper\nov-install\n# Select remote mode, enter your OpenViking server URL and API Key\n```\n\n### Step 2: Start and Verify\n\n```bash\nopenclaw gateway restart\nopenclaw status\n```\n\n<details>\n<summary>Manual configuration (without setup helper)</summary>\n\n```bash\nopenclaw plugins enable openviking\nopenclaw config set gateway.mode local\nopenclaw config set plugins.slots.contextEngine openviking\nopenclaw config set plugins.entries.openviking.config.mode remote\nopenclaw config set plugins.entries.openviking.config.baseUrl \"http://your-server:1933\"\nopenclaw config set plugins.entries.openviking.config.apiKey \"your-api-key\"\nopenclaw config set plugins.entries.openviking.config.agentId \"your-agent-id\"\nopenclaw config set plugins.entries.openviking.config.autoRecall true --json\nopenclaw config set plugins.entries.openviking.config.autoCapture true --json\n```\n\n</details>\n\n## Method 3: Integrating Openclaw with OpenViking on Volcengine ECS\n\nThis section primarily introduces how to connect Openclaw to OpenViking on Volcengine ECS and use the WebConsole to verify the data write. For details, please refer to the [documentation](https://www.volcengine.com/docs/6396/2249500?lang=zh).\n\nPlease note that to protect the system Python from being corrupted, the ECS instance has restrictions on deployments in the root directory and does not allow installing global packages directly using `pip`. It is recommended to create a virtual environment first and complete the following steps within it.\n\n**Prerequisites:** An existing ECS OpenClaw instance.\n\n### Step 1: npm Installation\n\n```bash\nnpm install -g openclaw-openviking-setup-helper\nov-install\n\n```\n\nThis installation mode already includes built-in VLM and embedding models in OpenViking. If no modifications are needed, simply press Enter and follow the prompts to enter your API key. After the installation is complete, a configuration file will be automatically generated. To modify it, enter `vim ~/.openviking/ov.conf`, press `i` to enter edit mode, press the `Esc` key to exit edit mode, then type `:wq` and press Enter to save and exit the file.\n\nLoad the OpenClaw environment variables in the terminal:\n\n```bash\nsource /root/.openclaw/openviking.env\n\n```\n\n### Step 2: Start OpenViking\n\nFirst, start the OpenViking Server:\n\n```bash\npython -m openviking.server.bootstrap\n\n```\n\nNext, start the web console. Before starting, you need to confirm whether the instance's security group has opened TCP port 8020 in the inbound rules. If not, please configure the instance security group first:\n\n```bash\npython -m openviking.console.bootstrap --host 0.0.0.0 --port 8020 --openviking-url http://127.0.0.1:1933\n\n```\n\nIn the instance, find your server's public IP, and use it to access: `http://<your-server-public-ip>:8020`\n\nYou can now start experiencing the web console 🎉\n\nYou can directly query file information on the web interface to verify whether the openclaw-plugin memory write is effective; you can also verify if openclaw-plugin is reading memories in the OpenClaw logs. The verification method is as follows:\n\n```bash\ngrep -i inject /tmp/openclaw/openclaw-2026-03-13.log | awk -F'\"' '{for(i=1;i<=NF;i++) if($i ~ /^[0-9]{2}:[0-9]{2}:[0-9]{2}/) {time=$i; break}} /injecting [0-9]+ memories/ {print time, \"openviking:\", gensub(/.*(injecting [0-9]+ memories).*/, \"\\\\1\", \"1\")}'\n\n```\n\nAlternatively, you can directly run `grep \"inject\" /tmp/openclaw/openclaw-2026-03-13.log` to view all the information.\n\n---\n\n## Configuration Reference\n\n### `~/.openviking/ov.conf` (Local Mode)\n\n```json\n{\n  \"root_api_key\": null,\n  \"server\": { \"host\": \"127.0.0.1\", \"port\": 1933 },\n  \"storage\": {\n    \"workspace\": \"/home/yourname/.openviking/data\",\n    \"vectordb\": { \"backend\": \"local\" },\n    \"agfs\": { \"backend\": \"local\", \"port\": 1833 }\n  },\n  \"embedding\": {\n    \"dense\": {\n      \"provider\": \"volcengine\",\n      \"api_key\": \"<your-ark-api-key>\",\n      \"model\": \"doubao-embedding-vision-251215\",\n      \"api_base\": \"https://ark.cn-beijing.volces.com/api/v3\",\n      \"dimension\": 1024,\n      \"input\": \"multimodal\"\n    }\n  },\n  \"vlm\": {\n    \"provider\": \"volcengine\",\n    \"api_key\": \"<your-ark-api-key>\",\n    \"model\": \"doubao-seed-2-0-pro-260215\",\n    \"api_base\": \"https://ark.cn-beijing.volces.com/api/v3\"\n  }\n}\n\n```\n\n> `root_api_key`: Once set, all HTTP requests must carry the `X-API-Key` header. Defaults to `null` in local mode (authentication disabled).\n\n### `agentId` Configuration (Plugin Configuration)\n\nThe Agent identifier passed to the server via the `X-OpenViking-Agent` header, used to distinguish different OpenClaw instances.\n\nCustomization method:\n\n```bash\n# Specify in the plugin configuration\nopenclaw config set plugins.entries.openviking.config.agentId \"my-agent\"\n\n```\n\nIf not configured, the plugin auto-generates a unique ID in the format `openclaw-<hostname>-<random>`.\n\n### `~/.openclaw/openviking.env`\n\nAutomatically generated by the setup helper, recording environment variables such as the Python path:\n\n```bash\nexport OPENVIKING_PYTHON='/usr/local/bin/python3'\n\n```\n\n---\n\n## Daily Usage\n\n```bash\n# Start\nsource ~/.openclaw/openviking.env && openclaw gateway\n\n# Disable the context engine\nopenclaw config set plugins.slots.contextEngine legacy\n\n# Enable OpenViking as the context engine\nopenclaw config set plugins.slots.contextEngine openviking\n\n```\n\n---\n\n## Troubleshooting\n\n| Symptom | Cause | Fix |\n| --- | --- | --- |\n| `port occupied` | Port occupied by another process | Change port: `openclaw config set plugins.entries.openviking.config.port 1934` |\n| `extracted 0 memories` | API Key or model name configured incorrectly | Check the `api_key` and `model` fields in `ov.conf` |\n| Plugin not loaded | Environment variables not loaded | Execute `source ~/.openclaw/openviking.env` before starting |\n| `externally-managed-environment` | Python PEP 668 restriction | Use venv or the one-click installation script |\n| `TypeError: unsupported operand type(s) for｜` | Python < 3.10 | Upgrade Python to 3.10+ |\n\n---\n\n## Uninstallation\n\n```bash\nlsof -ti tcp:1933 tcp:1833 tcp:18789 | xargs kill -9\nnpm uninstall -g openclaw && rm -rf ~/.openclaw\npython3 -m pip uninstall openviking -y && rm -rf ~/.openviking\n\n```\n\n---\n\n**See also:** [INSTALL-ZH.md](https://github.com/volcengine/OpenViking/blob/main/examples/openclaw-plugin/INSTALL-ZH.md) (Chinese) · [INSTALL-AGENT.md](https://github.com/volcengine/OpenViking/blob/main/examples/openclaw-plugin/INSTALL-AGENT.md) (Agent Install Guide)\n\n---\n"

    "content": "# OpenClaw + OpenViking Context-Engine Plugin\n\nUse [OpenViking](https://github.com/volcengine/OpenViking) as the long-term memory backend for [OpenClaw](https://github.com/openclaw/openclaw). In OpenClaw, this plugin is registered as the `openviking` context engine. Once installed, OpenClaw will automatically **remember** important information from conversations and **recall** relevant context before responding.\n\n> **ℹ️ Historical Compatibility Note**\n>\n> Legacy OpenViking/OpenClaw integrations had a known issue around OpenClaw `2026.3.12` where conversations could hang after the plugin loaded.\n> That issue affected the legacy plugin path; the current context-engine Plugin 2.0 described in this document is not affected, so new installations do not need to downgrade OpenClaw for this reason.\n> Plugin 2.0 is also not backward-compatible with the legacy `memory-openviking` plugin and its configuration, so upgrades must replace the old setup instead of mixing the two versions.\n> Plugin 2.0 also depends on OpenClaw's context-engine capability and does not support older OpenClaw releases; upgrade OpenClaw first before using this plugin.\n> If you are troubleshooting a legacy deployment, see [#591](https://github.com/volcengine/OpenViking/issues/591) and upstream fix PRs: openclaw/openclaw#34673, openclaw/openclaw#33547.\n\n> **🚀 Plugin 2.0 (Context-Engine Architecture)**\n>\n> This document covers the current OpenViking Plugin 2.0 built on the context-engine architecture, which is the recommended integration path for AI coding assistants.\n> For design background and earlier discussion, see:\n> https://github.com/volcengine/OpenViking/discussions/525\n\n---\n\n## Table of Contents\n\n- [One-Click Installation](#one-click-installation)\n- [Manual Setup](#manual-setup)\n  - [Prerequisites](#prerequisites)\n  - [Local Mode (Personal Use)](#local-mode-personal-use)\n  - [Remote Mode (Team Sharing)](#remote-mode-team-sharing)\n  - [Volcengine ECS Deployment](#volcengine-ecs-deployment)\n- [Starting & Verification](#starting--verification)\n- [Configuration Reference](#configuration-reference)\n- [Daily Usage](#daily-usage)\n- [Web Console (Visualization)](#web-console-visualization)\n- [Troubleshooting](#troubleshooting)\n- [Uninstallation](#uninstallation)\n\n---\n\n## One-Click Installation\n\nFor users who want a quick local experience.

The memory service runs alongside your OpenClaw agent locally. You only need a Volcengine Ark API Key.\n\n#### Step 1: Install OpenViking\n\n```bash\npython3 -m pip install openviking --upgrade\n```\n\nVerify: `python3 -c \"import openviking; print('ok')\"`\n\n> Hit `externally-managed-environment`? Use the one-click installer (handles venv automatically) or create one manually:\n> ```bash\n> python3 -m venv ~/.openviking/venv && ~/.openviking/venv/bin/pip install openviking\n> ```\n\n#### Step 2: Run the Setup Helper\n\n```bash\n# Method A: npm install (recommended, cross-platform)\nnpm install -g openclaw-openviking-setup-helper\nov-install\n\n# Method B: curl one-click (Linux / macOS)\ncurl -fsSL https://raw.githubusercontent.com/volcengine/OpenViking/main/examples/openclaw-plugin/install.sh | bash\n```\n\nSelect **local** mode, keep defaults, and enter your Ark API Key.\n\nGenerated config files:\n- `~/.openviking/ov.conf` — OpenViking service config\n- `~/.openclaw/openviking.env` — Environment variables (Python path, etc.)\n\n#### Step 3: Start\n\n```bash\nsource ~/.openclaw/openviking.env && openclaw gateway restart\n```\n\n> In Local mode you must `source` the env file first — the plugin auto-starts an OpenViking subprocess.\n\n#### Step 4: Verify\n\n```bash\nopenclaw status\n# ContextEngine row should show: enabled (plugin openviking)\n```\n\n---\n\n### Remote Mode (Team Sharing)\n\nFor multiple OpenClaw instances or team use. Deploy a standalone OpenViking service that is shared across agents. **No Python/OpenViking needed on the client side.**\n\n#### Step 1: Deploy the OpenViking Service\n\nEdit `~/.openviking/ov.conf` — set `root_api_key` to enable multi-tenancy:\n\n```json\n{\n  \"server\": {\n    \"host\": \"127.0.0.1\",\n    \"port\": 1933,\n    \"root_api_key\": \"<your-root-api-key>\",\n    \"cors_origins\": [\"*\"]\n  },\n  \"storage\": {\n    \"workspace\": \"~/.openviking/data\",\n    \"vectordb\": {\n      \"name\": \"context\",\n      \"backend\": \"local\"\n    },\n    \"agfs\": {\n      \"log_level\": \"warn\",\n      \"backend\": \"local\"\n    }\n  },\n  \"embedding\": {\n    \"dense\": {\n      \"provider\": \"volcengine\",\n      \"api_key\": \"<your-ark-api-key>\",\n      \"model\": \"doubao-embedding-vision-251215\",\n      \"api_base\": \"https://ark.cn-beijing.volces.com/api/v3\",\n      \"dimension\": 1024,\n      \"input\": \"multimodal\"\n    }\n  },\n  \"vlm\": {\n    \"provider\": \"volcengine\",\n    \"api_key\": \"<your-ark-api-key>\",\n    \"model\": \"doubao-seed-2-0-pro-260215\",\n    \"api_base\": \"https://ark.cn-beijing.volces.com/api/v3\",\n    \"temperature\": 0.1,\n    \"max_retries\": 3\n  }\n}\n```\n\nStart the service:\n\n```bash\nopenviking-server\n```\n\n#### Step 2: Create Team & Users\n\n```bash\n# Create team + admin\ncurl -X POST http://localhost:1933/api/v1/admin/accounts \\\n  -H \"Content-Type: application/json\" \\\n  -H \"X-API-Key: <root-api-key>\" \\\n  -d '{\n    \"account_id\": \"my-team\",\n    \"admin_user_id\": \"admin\"\n  }'\n\n# Add member\ncurl -X POST http://localhost:1933/api/v1/admin/accounts/my-team/users \\\n  -H \"Content-Type: application/json\" \\\n  -H \"X-API-Key: <root-or-admin-key>\" \\\n  -d '{\n    \"user_id\": \"xiaomei\",\n    \"role\": \"user\"\n  }'\n```\n\n#### Step 3: Configure the OpenClaw Plugin\n\n```bash\nopenclaw plugins enable openviking\nopenclaw config set gateway.mode local\nopenclaw config set plugins.slots.contextEngine openviking\nopenclaw config set plugins.entries.openviking.config.mode remote\nopenclaw config set plugins.entries.openviking.config.baseUrl \"http://your-server:1933\"\nopenclaw config set plugins.entries.openviking.config.apiKey \"<user-api-key>\"\nopenclaw config set plugins.entries.openviking.config.agentId \"<agent-id>\"\nopenclaw config set plugins.entries.openviking.config.autoRecall true --json\nopenclaw config set plugins.entries.openviking.config.autoCapture true --json\n```\n\n#### Step 4: Start & Verify\n\n```bash\n# Remote mode — no env sourcing needed\nopenclaw gateway restart\nopenclaw status\n```\n\n---\n\n### Volcengine ECS Deployment\n\nDeploy OpenClaw + OpenViking on Volcengine ECS.

Once installed, the plugin automatically remembers important facts from conversations and recalls relevant context before responding.\n---\n\n# OpenViking Memory Guide\n\n## How It Works\n\n- **Auto-Capture**: At `afterTurn` (end of one user turn run), automatically extracts memories from user/assistant messages\n  - `semantic` mode: captures all qualifying user text, relying on OpenViking's extraction pipeline to filter\n  - `keyword` mode: only captures text matching trigger words (e.g. \"remember\", \"preference\", etc.)\n- **Auto-Recall**: At `before_prompt_build`, automatically searches for relevant memories and injects them into context\n\n## Available Tools\n\n### memory_recall — Search Memories\n\nSearches long-term memories in OpenViking, returns relevant results.\n\n| Parameter | Required | Description |\n|-----------|----------|-------------|\n| `query` | Yes | Search query text |\n| `limit` | No | Maximum number of results (defaults to plugin config) |\n| `scoreThreshold` | No | Minimum relevance score 0-1 (defaults to plugin config) |\n| `targetUri` | No | Search scope URI (defaults to plugin config) |\n\nExample: User asks \"What programming language did I say I like?\"\n\n### memory_store — Manual Store\n\nWrites text to an OpenViking session and runs memory extraction.\n\n| Parameter | Required | Description |\n|-----------|----------|-------------|\n| `text` | Yes | Information text to store |\n| `role` | No | Session role (default `user`) |\n| `sessionId` | No | Existing OpenViking session ID |\n\nExample: User says \"Remember my email is xxx@example.com\"\n\n### memory_forget — Delete Memories\n\nDelete by exact URI, or search and delete.\n\n| Parameter | Required | Description |\n|-----------|----------|-------------|\n| `uri` | No | Exact memory URI (direct delete) |\n| `query` | No | Search query (find then delete) |\n| `targetUri` | No | Search scope URI |\n| `limit` | No | Search limit (default 5) |\n| `scoreThreshold` | No | Minimum relevance score |\n\nExample: User says \"Forget my phone number\"\n\n## Configuration\n\n| Field | Default | Description |\n|-------|---------|-------------|\n| `mode` | `remote` | `local` (start local server) or `remote` (connect to remote) |\n| `baseUrl` | `http://127.0.0.1:1933` | OpenViking server URL (remote mode) |\n| `apiKey` | — | OpenViking API Key (optional) |\n| `agentId` | `default` | Identifies this agent to OpenViking |\n| `configPath` | `~/.openviking/ov.conf` | Config file path (local mode) |\n| `port` | `1933` | Local server port (local mode) |\n| `targetUri` | `viking://user/memories` | Default search scope |\n| `autoCapture` | `true` | Automatically capture memories |\n| `captureMode` | `semantic` | Capture mode: `semantic` / `keyword` |\n| `captureMaxLength` | `24000` | Maximum text length per capture |\n| `autoRecall` | `true` | Automatically recall and inject context |\n| `recallLimit` | `6` | Maximum memories injected during auto-recall |\n| `recallScoreThreshold` | `0.01` | Minimum relevance score for recall |\n| `ingestReplyAssist` | `true` | Add reply guidance when detecting multi-party conversation text |\n\n## Daily Operations\n\n```bash\n# Start (local mode: source env first)\nsource ~/.openclaw/openviking.env && openclaw gateway\n\n# Start (remote mode: no env needed)\nopenclaw gateway\n\n# Check status\nopenclaw status\nopenclaw config get plugins.slots.contextEngine\n\n# Disable memory\nopenclaw config set plugins.slots.contextEngine legacy\n\n# Enable memory\nopenclaw config set plugins.slots.contextEngine openviking\n```\n\nRestart the gateway after changing the slot.\n\n## Multi-Instance Support\n\nIf you have multiple OpenClaw instances, use `--workdir` to target a specific one:\n\n```bash\n# Install script\ncurl -fsSL ... | bash -s -- --workdir ~/.openclaw-openclaw-second\n\n# Setup helper\nnpx ./examples/openclaw-plugin/setup-helper --workdir ~/.openclaw-openclaw-second\n\n# Manual config (prefix openclaw commands)\nOPENCLAW_STATE_DIR=~/.openclaw-openclaw-second openclaw config set ...\n```\n\n## Troubleshooting\n\n| Symptom | Cause | Fix |\n|---------|-------|-----|\n| `extracted 0 memories` | Wrong API Key or model name | Check `api_key` and `model` in `ov.conf` |\n| `port occupied` | Port used by another process | Change port: `openclaw config set plugins.entries.openviking.config.port 1934` |\n| Plugin not loaded | Env file not sourced or slot not configured | Check `openclaw status` output |\n| Inaccurate recall | recallScoreThreshold too low | Increase threshold or adjust recallLimit |\n"

If it's not already started:\n\n```bash\nopenviking-server > /tmp/openviking.log 2>&1 &\n```\n\n## Usage in OpenCode\n\nAdd the plugin to `~/.config/opencode/opencode.json`:\n\n```json\n{\n  \"plugin\": [\"openviking-opencode\"]\n}\n```\n\nRestart OpenCode — the skill is installed automatically.\n\n**Index a repo** (just ask in chat):\n```\n\"Add https://github.com/tiangolo/fastapi to OpenViking\"\n```\n\n**Search** — once repos are indexed, the AI searches them automatically when relevant. You can also trigger it explicitly:\n```\n\"How does fastapi handle dependency injection?\"\n\"Use openviking to find how JWT tokens are verified\"\n```\n\n"

Execute directly — no pre-checks, no test commands. Handle errors when they occur.**\n\n## How OpenViking Organizes Data\n\nOpenViking stores content in a virtual filesystem under the `viking://` namespace. Each URI maps to a file or directory, e.g. `viking://resources/fastapi/routing.py`. Each directory has AI-generated summaries (`abstract` / `overview`). **The key principle: narrow the URI scope to improve retrieval efficiency.** Instead of searching all repos, lock to a specific repo or subdirectory — this reduces noise and speeds up results significantly.\n\n## Search Commands\n\nChoose the right command based on what you're looking for:\n\n| Command | Use when | Example |\n|---------|----------|---------|\n| `ov search` | Semantic search — use for concept/intent based queries | \"dependency injection\", \"how auth works\" |\n| `ov grep` | You know the **exact keyword or symbol** | function name, class name, error string |\n| `ov glob` | You want to **enumerate files** by pattern | all `*.py` files, all test files |\n\n```bash\n# Semantic search\nov search \"dependency injection\" --uri viking://resources/fastapi --limit 10\nov search \"how tokens are refreshed\" --uri viking://resources/fastapi/fastapi/security\nov search \"JWT authentication\" --limit 10          # across all repos\nov search \"error handling\" --limit 5 --threshold 0.7  # filter low-relevance results\n\n# Keyword search — exact match or regex\nov grep \"verify_token\" --uri viking://resources/fastapi\nov grep \"class.*Session\" --uri viking://resources/requests/requests\n\n# File enumeration — by name pattern (always specify --uri to scope the search)\nov glob \"**/*.py\" --uri viking://resources/fastapi\nov glob \"**/test_*.py\" --uri viking://resources/fastapi/tests\nov glob \"**/*.py\" --uri viking://resources/   # across all repos\n```\n\n**Narrowing scope:** once you identify a relevant directory, pass it as `--uri` to restrict subsequent searches to that subtree — this is faster and more precise than searching the whole repo.\n\n**Query formulation:** write specific, contextual queries rather than single keywords.\n```bash\nov search \"API\"                                                       # too vague\nov search \"REST API authentication with JWT tokens\"                   # better\nov search \"JWT token refresh flow\" --uri viking://resources/backend   # best\n```\n\n## Read Content\n\n```bash\n# Directories: AI-generated summaries\nov abstract viking://resources/fastapi/fastapi/dependencies/   # one-line summary\nov overview viking://resources/fastapi/fastapi/dependencies/   # detailed breakdown\n\n# Files: raw content\nov read viking://resources/fastapi/fastapi/dependencies/utils.py\nov read viking://resources/fastapi/fastapi/dependencies/utils.py --offset 100 --limit 50\n```\n\n`abstract` / `overview` only work on directories. `read` only works on files.\n\n## Browse\n\n```bash\nov ls viking://resources/                        # list all indexed repos\nov ls viking://resources/fastapi                 # list repo top-level contents\nov ls viking://resources/fastapi --simple        # paths only, no metadata\nov ls viking://resources/fastapi --recursive     # list all files recursively\nov tree viking://resources/fastapi               # full directory tree (default: 3 levels deep)\nov tree viking://resources/fastapi -L 2          # limit depth to 2 levels\nov tree viking://resources/fastapi -l 200        # truncate abstract column to 200 chars\nov tree viking://resources/fastapi -L 2 -l 200   # combined: 2 levels deep, 200-char summaries\n```\n\n`-L` controls how many levels deep the tree expands. `-l` controls the length of the AI-generated summary per directory. Use `ov tree -L 2 -l 200` as a good starting point to understand a repo's structure before diving in.\n\n## Add a Repository\n\n```bash\nov add-resource https://github.com/owner/repo --to viking://resources/repo --timeout 300\n```\n\n`--timeout` is required (seconds). Use 300 (5 min) for small repos, increase for larger ones.\n\nAfter submitting, run `ov observer queue` once and report status to user. Indexing runs in background — do not poll or wait.\n\n| Repo Size | Files | Est. Time |\n|-----------|-------|-----------|\n| Small | < 100 | 2–5 min |\n| Medium | 100–500 | 5–20 min |\n| Large | 500+ | 20–60+ min |\n\n## Remove a Repository\n\n```bash\nov rm viking://resources/fastapi --recursive\n```\n\nThis permanently deletes the repo and all its indexed content. Confirm with the user before running.\n\n## Error Handling\n\n**`command not found: ov`** → Tell user: `pip install openviking --upgrade`. Stop.\n\n**`url is required` / `CLI_CONFIG` error** → Auto-create config and retry:\n```bash\nmkdir -p ~/.openviking && echo '{\"url\": \"http://localhost:1933\"}' > ~/.openviking/ovcli.conf\n```\n\n**`CONNECTION_ERROR` / failed to connect:**\n- `~/.openviking/ov.conf` **exists** → auto-start server, wait until healthy, retry:\n  ```bash\n  openviking-server > /tmp/openviking.log 2>&1 &\n  for i in $(seq 1 10); do ov health 2>/dev/null && break; sleep 3; done\n  ```\n- **Does not exist** → Tell user to configure `~/.openviking/ov.conf` first. Stop.\n\n## More Help\n\nFor other issues or command details, run:\n\n```bash\nov help\nov <command> --help   # e.g. ov search --help\n```\n"

    "content": "# 为 OpenCode 安装 OpenViking Memory Plugin\n\n这个示例把 OpenViking 暴露为 OpenCode 可直接调用的记忆工具，并自动把当前对话同步到 OpenViking Session 中。\n\n安装完成后，你可以在 OpenCode 中使用这些工具：\n\n- `memsearch`\n- `memread`\n- `membrowse`\n- `memcommit`\n\n---\n\n## 机制说明\n\n这个示例使用的是 OpenCode 的 tool 机制，把 OpenViking 能力显式暴露成 Agent 可调用的工具。\n\n更具体一点：\n\n- Agent 会看到 `memsearch`、`memread`、`membrowse`、`memcommit` 这些显式工具\n- 只有在 Agent 主动调用这些工具时，OpenViking 的内容才会被读取回来\n- 插件还会在后台把 OpenCode session 映射到 OpenViking session，并在合适的时候触发记忆提取\n\n这个示例的重点是显式 memory 访问、类文件系统浏览，以及会话到长期记忆的自动同步。\n\n---\n\n## 前置条件\n\n你需要先准备：\n\n- 已安装 OpenCode\n- 已启动 OpenViking HTTP Server\n- 可用的 OpenViking API Key（如果服务端启用了认证）\n\n建议先确认 OpenViking 服务正常运行：\n\n```bash\nopenviking-server --config ~/.openviking/ov.conf\n```\n\n如果你已经在后台启动了服务，也可以直接检查健康状态：\n\n```bash\ncurl http://localhost:1933/health\n```\n\n---\n\n## 安装步骤\n\nOpenCode 官方文档更推荐把插件放在：\n\n```bash\n~/.config/opencode/plugins\n```\n\n### Step 1: 创建插件目录\n\n```bash\nmkdir -p ~/.config/opencode/plugins\n```\n\n### Step 2: 复制示例文件\n\n在 OpenViking 仓库根目录执行：\n\n```bash\ncp examples/opencode-memory-plugin/openviking-memory.ts ~/.config/opencode/plugins/openviking-memory.ts\ncp examples/opencode-memory-plugin/openviking-config.example.json ~/.config/opencode/plugins/openviking-config.json\ncp examples/opencode-memory-plugin/.gitignore ~/.config/opencode/plugins/.gitignore\n```\n\n复制后，插件目录里应该至少有这些文件：\n\n```text\n~/.config/opencode/plugins/\n├── .gitignore\n├── openviking-config.json\n└── openviking-memory.ts\n```\n\n### Step 3: 配置插件\n\n编辑：\n\n```bash\n~/.config/opencode/plugins/openviking-config.json\n```\n\n示例配置：\n\n```json\n{\n  \"endpoint\": \"http://localhost:1933\",\n  \"apiKey\": \"\",\n  \"enabled\": true,\n  \"timeoutMs\": 30000,\n  \"autoCommit\": {\n    \"enabled\": true,\n    \"intervalMinutes\": 10\n  }\n}\n```\n\n字段说明：\n\n- `endpoint`: OpenViking 服务地址\n- `apiKey`: 可留空，推荐用环境变量提供\n- `enabled`: 是否启用插件\n- `timeoutMs`: 普通请求超时时间\n- `autoCommit.intervalMinutes`: 自动提交 session 的周期\n\n### Step 3.5: 关于插件注册\n\n这个插件不需要额外写进 `~/.config/opencode/opencode.json`。\n\n原因是 OpenCode 会自动扫描 `~/.config/opencode/plugins/` 下面的一级 `*.ts` / `*.js` 文件，`openviking-memory.ts` 放在这个目录顶层即可被发现。\n\n### Step 4: 配置 API Key\n\n推荐使用环境变量，不要把真实 key 写进配置文件：\n\n```bash\nexport OPENVIKING_API_KEY=\"your-api-key-here\"\n```\n\n如果你使用 `zsh`，可以把它写进 `~/.zshrc`：\n\n```bash\necho 'export OPENVIKING_API_KEY=\"your-api-key-here\"' >> ~/.zshrc\nsource ~/.zshrc\n```\n\n---\n\n## 启动与验证\n\n配置完成后，正常启动 OpenCode 即可。\n\n插件初始化后会：\n\n- 对 OpenViking 做一次 health check\n- 为每个 OpenCode session 自动建立对应的 OpenViking session\n- 自动把用户消息和 assistant 消息写入 OpenViking\n- 按周期触发后台 `commit`\n\n你可以在会话里尝试：\n\n```text\n请用 memsearch 搜索我之前的偏好\n```\n\n或者手动触发一次记忆提取：\n\n```text\n请调用 memcommit\n```\n\n---\n\n## 运行时文件\n\n插件运行后，会在插件目录里生成这些本地文件：\n\n- `~/.config/opencode/plugins/openviking-config.json`\n- `~/.config/opencode/plugins/openviking-memory.log`\n- `~/.config/opencode/plugins/openviking-session-map.json`\n\n这些文件都是运行时产物，不建议提交到版本库。示例里的 `.gitignore` 已经帮你排除了它们。\n\n如果你明确希望按工作区隔离插件，也可以把这三个文件和 `openviking-memory.ts` 一起放在工作区本地插件目录里。当前实现会把配置和运行时文件统一保存在“插件文件所在目录”。\n\n---\n\n## 常见问题\n\n### 1. 插件没有生效\n\n先确认文件位置正确：\n\n```bash\nls ~/.config/opencode/plugins/\n```\n\n至少要能看到：\n\n- `openviking-memory.ts`\n- `openviking-config.json`\n\n### 2. `Authentication failed`\n\n通常是 API Key 配置不对。优先检查：\n\n- `OPENVIKING_API_KEY` 是否已设置\n- 服务端是否启用了认证\n- `endpoint` 是否连到了正确的 OpenViking 服务\n\n### 3. `Service unavailable`\n\n说明插件连不上 OpenViking 服务。检查：\n\n```bash\ncurl http://localhost:1933/health\n```\n\n如果失败，先启动：\n\n```bash\nopenviking-server --config ~/.openviking/ov.conf\n```\n\n### 4. `memcommit` 很慢或经常超时\n\n这个示例已经改成了后台 commit task 模式。一般情况下，即使记忆提取比较慢，也不应该再出现“每分钟同步重试一次”的风暴。\n\n如果你仍然觉得慢，优先检查的是：\n\n- OpenViking 服务端的模型配置\n- 服务端所在机器的资源是否吃满\n- `openviking-memory.log` 里是否有持续的 task failure\n\n### 5. 没有抽出任何 memory\n\n通常不是插件没工作，而是服务端提取条件不满足。优先检查：\n\n- OpenViking 的 `vlm` 和 `embedding` 是否已正确配置\n- 当前对话里是否真的有适合沉淀为 memory 的内容\n\n---\n\n## 相关文件\n\n- [README.md](./README.md): English overview\n- [openviking-memory.ts](./openviking-memory.ts): plugin implementation\n- [openviking-config.example.json](./openviking-config.example.json): config template\n"

    "content": "# OpenViking Memory Plugin for OpenCode\n\nOpenCode plugin example that exposes OpenViking memories as explicit tools and automatically syncs conversation sessions into OpenViking.\n\nChinese install guide: [INSTALL-ZH.md](./INSTALL-ZH.md)\n\n## Mechanism\n\nThis example uses OpenCode's tool mechanism to expose OpenViking capabilities as explicit agent-callable tools.\n\nIn practice, that means:\n\n- the agent sees concrete tools and decides when to call them\n- OpenViking data is fetched on demand through tool execution instead of being pre-injected into every prompt\n- the plugin also keeps an OpenViking session in sync with the OpenCode conversation and triggers background memory extraction with `memcommit`\n\nThis example focuses on explicit memory access, filesystem-style browsing, and session-to-memory synchronization inside OpenCode.\n\n## What It Does\n\n- Exposes four memory tools for OpenCode agents:\n  - `memsearch`\n  - `memread`\n  - `membrowse`\n  - `memcommit`\n- Automatically maps each OpenCode session to an OpenViking session\n- Streams user and assistant messages into OpenViking\n- Uses background `commit` tasks to avoid repeated synchronous timeout failures\n- Persists local runtime state for reconnect and recovery\n\n## Files\n\nThis example contains:\n\n- `openviking-memory.ts`: the plugin implementation used by OpenCode\n- `openviking-config.example.json`: template config\n- `.gitignore`: ignores local runtime files after you copy the example into a workspace\n\n## Prerequisites\n\n- OpenCode\n- OpenViking HTTP Server\n- A valid OpenViking API key if your server requires authentication\n\nStart the server first if it is not already running:\n\n```bash\nopenviking-server --config ~/.openviking/ov.conf\n```\n\n## Install Into OpenCode\n\nRecommended location from the OpenCode docs:\n\n```bash\n~/.config/opencode/plugins\n```\n\nInstall with:\n\n```bash\nmkdir -p ~/.config/opencode/plugins\ncp examples/opencode-memory-plugin/openviking-memory.ts ~/.config/opencode/plugins/openviking-memory.ts\ncp examples/opencode-memory-plugin/openviking-config.example.json ~/.config/opencode/plugins/openviking-config.json\ncp examples/opencode-memory-plugin/.gitignore ~/.config/opencode/plugins/.gitignore\n```\n\nThen edit `~/.config/opencode/plugins/openviking-config.json`.\n\nOpenCode auto-discovers first-level `*.ts` and `*.js` files under `~/.config/opencode/plugins`, so no explicit `plugin` entry is required in `~/.config/opencode/opencode.json`.\n\nThis plugin also works if you intentionally place it in a workspace-local plugin directory, because it stores config and runtime files next to the plugin file itself.\n\nRecommended: provide the API key via environment variable instead of writing it into the config file:\n\n```bash\nexport OPENVIKING_API_KEY=\"your-api-key-here\"\n```\n\n## Configuration\n\nExample config:\n\n```json\n{\n  \"endpoint\": \"http://localhost:1933\",\n  \"apiKey\": \"\",\n  \"enabled\": true,\n  \"timeoutMs\": 30000,\n  \"autoCommit\": {\n    \"enabled\": true,\n    \"intervalMinutes\": 10\n  }\n}\n```\n\nThe environment variable `OPENVIKING_API_KEY` takes precedence over the config file.\n\n## Runtime Files\n\nAfter installation, the plugin creates these local files next to the plugin file:\n\n- `openviking-config.json`\n- `openviking-memory.log`\n- `openviking-session-map.json`\n\nThese are runtime artifacts and should not be committed.\n\n## Tools\n\n### `memsearch`\n\nUnified search across memories, resources, and skills.\n\nParameters:\n\n- `query`: search query\n- `target_uri?`: narrow search to a URI prefix such as `viking://user/memories/`\n- `mode?`: `auto | fast | deep`\n- `limit?`: max results\n- `score_threshold?`: optional minimum score\n\n### `memread`\n\nRead content from a specific `viking://` URI.\n\nParameters:\n\n- `uri`: target URI\n- `level?`: `auto | abstract | overview | read`\n\n### `membrowse`\n\nBrowse the OpenViking filesystem layout.\n\nParameters:\n\n- `uri`: target URI\n- `view?`: `list | tree | stat`\n- `recursive?`: only for `view: \"list\"`\n- `simple?`: only for `view: \"list\"`\n\n### `memcommit`\n\nTrigger immediate memory extraction for the current session.\n\nParameters:\n\n- `session_id?`: optional explicit OpenViking session ID\n\nReturns background task progress or completion details, including `task_id`, `memories_extracted`, and `archived`.\n\n## Usage Examples\n\nSearch and then read:\n\n```typescript\nconst results = await memsearch({\n  query: \"user coding preferences\",\n  target_uri: \"viking://user/memories/\",\n  mode: \"auto\"\n})\n\nconst content = await memread({\n  uri: results[0].uri,\n  level: \"auto\"\n})\n```\n\nBrowse first:\n\n```typescript\nconst tree = await membrowse({\n  uri: \"viking://resources/\",\n  view: \"tree\"\n})\n```\n\nForce a mid-session commit:\n\n```typescript\nconst result = await memcommit({})\n```\n\n## Notes for Reviewers\n\n- The plugin is designed to run as a first-level `*.ts` file in the OpenCode plugins directory\n- It intentionally keeps runtime config, logs, and session maps outside the repository example\n- It uses OpenViking background commit tasks to avoid repeated timeout/retry loops during long memory extraction\n\n## Troubleshooting\n\n- Plugin not loading: confirm the file exists at `~/.config/opencode/plugins/openviking-memory.ts`\n- Service unavailable: confirm `openviking-server` is running and reachable at the configured endpoint\n- Authentication failed: check `OPENVIKING_API_KEY` or `openviking-config.json`\n- No memories extracted: check that your OpenViking server has working `vlm` and `embedding` configuration\n"

    "content": "---\nname: ov-add-data\ndescription: This skill adds data(like resources) to OpenViking Context Database (aka. ov). Use when an agent needs to add files, data from URLs, or external knowledge during interactions. Trigger this tool when 1. is explicitly requested adding files or knowledge; 2. identifies valuable resources worth importing; 3. the user mentioned adding to OV/OpenViking/Context Database. This skill helps how to use CLI like `ov add-resource`, `ov add-skill` and `ov add-memory` to add resource data, skill files, memory files to OpenViking.\ncompatibility: OpenViking CLI configured at `~/.openviking/ovcli.conf`\n---\n\n# OpenViking (OV) `add-resource`\n\nThe `ov add-resource` command imports external resources into OpenViking's context database — supporting local files, directories, URLs, and remote repositories. Resources are automatically processed with semantic analysis and organized under the `viking://resources/` namespace.\n\n## When to Use\n\n- Importing project documentation, code repositories, or reference materials\n- Adding web pages, articles, or online resources for future retrieval\n- Building a knowledge base from external sources\n- When an agent encounters valuable content that should persist across sessions\n- Recording a project's product documentation, design specs, or other valuable materials\n- Storing sensitive information or private data of the user, like photo and albums\n\n## CLI Options\n\n### Basic Usage\n\nImport a local file or URL:\n\n```bash\n# add a code repo from github or gitlab or a git address\nov add-resource https://github.com/volcengine/OpenViking\nov add-resource https://code.xxxx.org/viking/viking\nov add-resource git@code.xxxx.org:viking/viking.git\n\n# add a file from url\nov add-resource https://arxiv.org/pdf/2602.09540\nov add-resource https://raw.githubusercontent.com/volcengine/OpenViking/main/README.md\n\n# add a file from local filesystem\nov add-resource ./docs/api-spec.md\nov add-resource ./team_building.jpg\nov add-resource /User/volcengine/Documents/profile.pdf\nov add-resource /User/volcengine/Documents/project.docx\n\n# add a zip file from local filesystem (will be unzipped on server)\nov add-resource ./docs-of-project.zip\n\n# add a directory from local filesystem\nov add-resource /User/volcengine/Photo/Travels/2026/ --include \"*.jpg,*.jpeg,*.png\"\nov add-resource /User/volcengine/Documents/OV项目设计文档/\n```\n\n### Context and Instructions (TBD)\n\nAdd metadata to guide processing: --reason and --instruction will be supported in the future.\n\n### Async Processing Control\n\nThe time of adding resources could cost long (like minutes), and the semantic processing could be async. Use `--wait` to wait for the processing to complete.\n\n```bash\n# Wait until semantic processing finishes\nov add-resource ./docs --wait\n\n# Wait with timeout (in seconds)\nov add-resource https://example.com/docs --wait --timeout 60\n\n# Fire and forget (default, without --wait)\nov add-resource ./docs\n```\n\nIf you fire and forget, the command will return after the resource is completely downloaded/uploaded on server, and then the CLI will return the root URI of the imported resource. To check the status of the resource, you can use `ov ls` or `ov tree` to list the resources under root URI or `viking://resources/`.\n\n### Specify the target path\n\nBy default, resources are imported under `viking://resources/`. Use `--to` or `--parent` to specify a target uri.\n\n```bash\n# The data will be imported as viking://resources/2026/2026-01-01/, which should not exist before\nov add-resource /User/volcengine/Photo/Travels/2026/2026-01-01/ --to \"viking://resources/2026/2026-01-01/\"\n\n# The data will be imported under viking://resources/2026, which should exist and be a directory\nov add-resource /User/volcengine/Photo/Travels/2026/2026-01-02/ --parent \"viking://resources/2026/\"\n```\n\n## CLI Output\n\nReturns the root URI of the imported resource, like:\n\n```\nroot_uri  viking://resources/2026/2026-01-01\n```\n\n## CLI Prerequisites\n\n- CLI configured in: `~/.openviking/ovcli.conf`\n- Network access for the importing URL from server\n- Local read access for the importing local files/directories from CLI.\n\n# OpenViking (OV) `add-memory`\n\nThe `ov add-memory` command adds long persistant memory — turning text and structured conversations into searchable, retrievable memories in the OpenViking context database. Use `ov add-memory --help` for latest usage.\n\n## When to Use\n\n- After learning something worth remembering across sessions\n- To persist conversation insights, decisions, or findings\n- To build up a knowledge base from interactions\n- When an agent wants to store context for future retrieval\n\n## Input Modes\nchoose wisely between plain text and multi-turn mode. Multi-turn mode can contain more complex insights, let openviking handle the memory extraction.\n\n### Mode 1: Plain Text for compressed memory\n\nA simple string is stored as a `user` message:\n\n```bash\nov add-memory \"User's name is Bob, he participate in Global Hackathon in 2025-01-08, and won Champion.\"\n```\n\n### Mode 2: Multi-turn Conversation for Richer Context\n\nA JSON array of `{role, content}` objects to store a full exchange:\n\n```bash\nov add-memory '[\n  {\"role\": \"user\", \"content\": \"I love traveling. Give me some options of Transport from Beijing to Shanghai.\"},\n  {\"role\": \"assistant\", \"content\": \"You can use train, bus, or plane. Train is the fastest, but you need to book in advance. Bus is cheaper, but you need to wait. Plane is the most expensive, but you can get there any time of day.\"},\n  {\"role\": \"user\", \"content\": \"I prefer train. I like sightseeing on the train. Can you give me the train schedule?\"},\n  < ... more possible conversation about schedule and tickest need to be memorized ... >\n]'\n```\n\n## Output\n\nReturns count of memory extracted:\n\n```\nmemories_extracted   1\n```\n\n## Agent Best Practices\n\n### How to Write Good Memories\n\n1. **Be specific** — Include concrete details, not vague summaries\n2. **Include context** — Why this matters, when it applies\n3. **Use structured format** — Separate the what from the why\n\n### Batch Related Facts\n\nGroup related memories in one call rather than many small ones:\n\n```bash\nov add-memory '[\n  {\"role\": \"user\", \"content\": \"Key facts about the ov_cli Rust crate\"},\n  {\"role\": \"assistant\", \"content\": \"1. runs faster than python cli\\n2. uses HttpClient to connect openviking server\\n3. Output formatting supports table and JSON modes\\n4. Config lives at ~/.openviking/ovcli.conf\"}\n]'\n```\n\n## Prerequisites\n\n- CLI configured: `~/.openviking/ovcli.conf`\n\n# OpenViking (OV) `add-skill`\n\nThe `ov add-skill` command adds agent capabilities to OpenViking — supporting SKILL.md files, MCP tool definitions, and raw skill content. Skills are automatically processed and organized under the `viking://agent/skills/` namespace, making them discoverable and usable by agents.\n\n## When to Use\n\n- Adding custom agent capabilities and workflows\n- Importing MCP (Model Context Protocol) tools\n- Persisting skill definitions across agent sessions\n- Building a library of reusable agent capabilities\n- When an agent needs to extend its toolset with custom logic\n\n## Input Formats\n\n### Mode 1: SKILL.md File\n\nImport from a single SKILL.md file with YAML frontmatter:\n\n```bash\n# Add from a single SKILL.md file\nov add-skill ./skills/my-skill/SKILL.md\n\n# Add from a directory containing SKILL.md (includes auxiliary files)\nov add-skill ./skills/my-skill/\n```\n\n## CLI Options\n\n### Async Processing Control\n\nSemantic processing happens asynchronously. Use `--wait` to block until complete:\n\n```bash\n# Wait until semantic processing finishes\nov add-skill ./skills/my-skill/ --wait\n\n# Wait with timeout (in seconds)\nov add-skill ./skills/my-skill/ --wait --timeout 60\n\n# Fire and forget (default, without --wait)\nov add-skill ./skills/my-skill/\n```\n\n## CLI Output\n\nReturns the URI of the added skill, like:\n\n```\nuri  viking://agent/skills/my-skill/\n```\n\n## SKILL.md Format\n\nSkills use Markdown with YAML frontmatter:\n\n```markdown\n---\nname: skill-name\ndescription: Brief description of the skill\nallowed-tools:\n  - Tool1\n  - Tool2\ntags:\n  - tag1\n  - tag2\n---\n\n## Including Auxiliary Files\n\nWhen adding from a directory, all files in the directory are included as auxiliary files:\n\n```bash\n# Directory structure:\n# ./skills/code-runner/\n#   ├── SKILL.md\n#   ├── helper.py\n#   └── templates/\n#       └── script.py\n\nov add-skill ./skills/code-runner/\n# Both helper.py and templates/ are included\n```\n\n## CLI Prerequisites\n\n- CLI configured: `~/.openviking/ovcli.conf`\n- The skill file (SKILL.md) should be in the correct markdown format.\n"

Check if port is in use\nlsof -i :1933\nnetstat -tulpn | grep 1933\n\n# 2. Check log for errors\ntail -10 ~/.openviking/log/openviking-server.log\ntail -100 ~/.openviking/log/openviking.log\n\n\n# 3. Verify config file is valid JSON\npython3 -c 'import json, os; json.load(open(os.path.expanduser(\"~/.openviking/ov.conf\"))); print(\"Config is valid\")'\n\n# 4. Verify virtual environment\nsource ~/.openviking/ov-venv/bin/activate\nwhich openviking-server\npip list | grep openviking\n```\n\n**Solution:**\n```bash\n# If port conflict: kill the process or use different port\nlsof -ti :1933 | xargs kill -9 2>/dev/null || true\n\n# Or start on different port\nnohup openviking-server --port 1934 > ~/.openviking/log/openviking-server.log 2>&1 &\n```\n\n#### Issue: API Key Errors\n\n**Check:**\n```bash\n# Verify API keys in config\npython3 -c '\nimport json, os\ncfg = json.load(open(os.path.expanduser(\"~/.openviking/ov.conf\")))\nprint(\"Embedding provider:\", cfg.get(\"embedding\", {}).get(\"dense\", {}).get(\"provider\"))\nprint(\"VLM provider:\", cfg.get(\"vlm\", {}).get(\"provider\"))\nprint(\"API keys set:\", bool(cfg.get(\"embedding\", {}).get(\"dense\", {}).get(\"api_key\")), bool(cfg.get(\"vlm\", {}).get(\"api_key\")))\n'\n```\n\n**Solution:** Verify API keys are correct and have the required permissions. Check network connectivity to the model provider endpoints. Ensure API keys are not expired.\n\n## Prerequisites\n\n- Python 3.10+ installed\n- uv package manager available\n- Sufficient disk space for workspace and log\n- API keys for embedding and VLM models configured\n- Network access to model providers (if using cloud models)\n"

Start OpenViking server (default: `http://127.0.0.1:1933`)\n2. Start the console service:\n\n```bash\npython -m openviking.console.bootstrap \\\n  --host 127.0.0.1 \\\n  --port 8020 \\\n  --openviking-url http://127.0.0.1:1933\n```\n\n3. Open:\n\n```text\nhttp://127.0.0.1:8020/\n```\n\n4. In **Settings**, paste your OpenViking `X-API-Key` and click **Save** (or press Enter).\n`X-API-Key` is configured in the web UI Settings panel and stored in browser session storage.\n\n## Startup parameters\n\n- `--openviking-url` (default `http://127.0.0.1:1933`)\n- `--host` (default `127.0.0.1`)\n- `--port` (default `8020`)\n- `--write-enabled` (default `false`)\n- `--request-timeout-sec` (default `30`)\n- `--cors-origins` (default `*`, comma-separated)\n\nWithout `--write-enabled`, write operations are blocked by backend guardrails.\nIf you need **Add Resource** or **multi-tenant management** (create/delete account, add/delete user, role/key changes),\nstart with `--write-enabled`.\n\nExample:\n\n```bash\npython -m openviking.console.bootstrap \\\n  --host 127.0.0.1 \\\n  --port 8020 \\\n  --openviking-url http://127.0.0.1:1933 \\\n  --write-enabled\n```\n"

./results.json\n```\n\n### 示例 3：基于本仓库的评估\n\n在 OpenViking 仓库根目录下执行：\n\n```bash\n# 评估文档检索效果\npython -m openviking.eval.ragas.rag_eval \\\n    --docs_dir ./docs \\\n    --docs_dir ./README.md \\\n    --question_file ./openviking/eval/datasets/local_doc_example_glm5.jsonl \\\n    --output ./eval_results.json\n```\n\n## 存储层评估\n\n### IO Recorder 录制器\n\nIO Recorder 用于录制评估过程中的所有 IO 操作（FS、VikingDB），记录请求参数、响应结果、耗时等信息。\n\n```python\nfrom openviking.eval.recorder import init_recorder, get_recorder\n\n# 初始化录制器\ninit_recorder(enabled=True)\n\n# 进行评估操作...\n# 操作会自动记录到 ./records/io_recorder_YYYYMMDD.jsonl\n\n# 获取统计信息\nrecorder = get_recorder()\nstats = recorder.get_stats()\nprint(f\"Total operations: {stats['total_count']}\")\nprint(f\"FS operations: {stats['fs_count']}\")\nprint(f\"VikingDB operations: {stats['vikingdb_count']}\")\n```\n\n### Record Analysis 分析器\n\nRecord Analysis 用于分析录制的 IO 操作，提供全面的统计信息。\n\n```bash\n# 分析所有记录\npython -m openviking.eval.ragas.analyze_records \\\n    --record_file ./records/io_recorder_20260214.jsonl\n\n# 只分析 FS 操作\npython -m openviking.eval.ragas.analyze_records \\\n    --record_file

MarkdownParser (`markdown.py`)\n**支持格式**: `.md`, `.markdown`, `.mdown`, `.mkd`\n\n核心文档解析器，所有文本类文档最终都通过 MarkdownParser 处理。采用 v5.0 简化架构：\n\n#### 解析逻辑（单阶段）\n- 按标题层级（#, ##, ###）拆分章节，支持混合目录结构（文件 + 子目录）\n- 切分规则：\n  - 小文件（< 4000 tokens）：保留原文件名，直接保存\n  - 大文件（> 4000 tokens）：按章节切分\n  - 章节有子章节且总大小 > 4000：章节变目录，直接内容视为第一个虚拟子章节参与合并\n  - 章节无子章节但超长：创建目录，按段落切分为 `章节名_1.md`, `章节名_2.md`\n  - 正常章节：保存为 `章节名.md`\n- 小章节合并规则（< 800 tokens）：\n  - 连续的小章节会合并，直到总大小 >= 800 tokens 或无法与下一个章节合并\n  - 合并后文件名用下划线拼接所有章节名：`章节A_章节B_章节C.md`\n  - 直接内容（标题前或子标题前的内容）视为虚拟章节，使用父级名称参与合并\n- 直接写入临时目录的文件和目录结构\n- **无 LLM 调用**：语义生成移到 SemanticQueue 异步处理\n\n#### 语义生成（异步，由 SemanticProcessor 处理）\n- TreeBuilder 将目录移到 AGFS 后，入队到 SemanticQueue\n- SemanticProcessor 自底向上处理每个目录：\n  - 收集子目录的 `.abstract.md`\n  - 并发生成文件 summary（LLM）\n  - 生成当前目录的 `.abstract.md` (L0) 和 `.overview.md` (L1)\n  - 直接调用向量化写入\n\n### 2. PDFParser (`pdf.py`)\n**支持格式**: `.pdf`\n\n统一 PDF 解析器，采用双策略转换：\n- **本地策略**: 使用 `pdfplumber` 进行文本和表格提取\n- **远程策略**: 使用 `MinerU API` 进行高级 PDF 处理\n- **自动策略**: 先尝试本地，失败时回退到 MinerU（如果配置了）\n\n处理流程：`PDF → Markdown → ParseResult`，最终通过 MarkdownParser 处理。\n\n### 3. HTMLParser (`html.py`)\n**支持格式**: `.html`, `.htm`\n\n使用 `readabilipy` 库提取可读内容，去除广告、导航等噪音元素，转换为 Markdown 后通过 MarkdownParser 处理。\n\n### 4. TextParser (`text.py`)\n**支持格式**: `.txt`, `.text`, `.log`, `.csv`, `.tsv`, `.json`, `.yaml`, `.yml`, `.xml`, `.ini`, `.cfg`, `.conf`\n\n纯文本解析器，支持多种文本格式。对于结构化格式（JSON、YAML、XML）会尝试提取结构化信息。\n\n### 5. CodeRepositoryParser (`code/*`)\n**支持来源**: github 代码仓库等\n\n代码解析器，支持语法高亮和代码结构分析。能识别函数、类、方法等代码元素。\n\n### 6. MediaParser (`media/*.py`)\n\n**支持格式**:\n- 图片: `.png`, `.jpg`, `.jpeg`, `.gif`, `.webp`\n- 视频: `.mp4`, `.mov`, `.avi`, `.webm`\n- 音频: `.mp3`, `.wav`, `.m4a`, `.flac`\n\n多媒体解析器，使用 VLM（视觉语言模型）分析图像、视频和音频内容，生成文本描述。多媒体解析器当且仅当 add-resource 调用时只添加上述文件类型时生效。即：\n1. 当添加目录时，系统将对多媒体文件暂不生成单独目录和文本描述，仅存储和进行递归摘要。\n2. 当单独添加多媒体文件时，多媒体解析器会直接解析该文件，然后通过单独目录存放，在目录下生成文本描述。\n\n#### 存储组织策略\n\n多媒体文件的存储采用以下层级结构：\n\n```\nviking://resource/\n├── images/     # 图片文件\n│   └── 20240820/  # 上传日期（YYYYMMDD）\n│       └── 20240820_123456_jpg/  # 文件文件夹（文件名_扩展名）\n│           ├── .abstract.md    # L0 摘要\n│           ├── .overview.md    # L1 概览\n│           └── 20240820_123456.jpg  # 原始文件\n├── audio/      # 音频文件\n│   └── 20240820/\n│       └── my_song_mp3/\n│           ├── .abstract.md\n│           ├── .overview.md\n│           └── my_song.mp3\n└── video/      # 视频文件\n    └── 20240820/\n        └── my_video_mp4/\n            ├── .abstract.md\n            ├── .overview.md\n            └── my_video.mp4\n```\n\n详细说明：\n\n1. **媒体子目录**: 在 `viking://resource` 下按类型划分为三个子目录\n   - `viking://resource/images`: 存储未明确指定目标路径的图片文件\n   - `viking://resource/audio`: 存储未明确指定目标路径的音频文件\n   - `viking://resource/video`: 存储未明确指定目标路径的视频文件\n\n2. **日期子目录**: 每次上传的文件按当前日期（格式：YYYYMMDD）组织，而非文件内部元信息的时间\n   - 例如：`viking://resource/images/20240820/` 存储 2024年8月20日上传的所有图片\n\n3. **文件文件夹**: 为每个多媒体文件创建一个专属文件夹，命名规则为：`文件名_扩展名`（扩展名不含点）\n   - 示例：上传 `20240820_123456.jpg` → 创建文件夹 `20240820_123456_jpg`\n\n4. **文件夹内容**: 每个文件文件夹内包含：\n   - **原始文件**: 保持原始文件名，空格字符替换为下划线 `_`（因为 OpenViking URI 不允许包含空格）\n     - 示例：`photo 1.jpg` → 保存为 `photo_1.jpg`\n   - `.abstract.md` (L0 层): 摘要信息（<200 token）\n     - 图片：文件名、内容描述、画面风格等\n     - 音频：文件名、时长、内容概述等\n     - 视频：文件名、时长、内容概述等\n   - `.overview.md` (L1 层): 概览信息\n     - 图片：除摘要外，还包含尺寸、OCR 识别结果、场景和主体描述等\n     - 音频：除摘要外，还包含语音/歌词识别结果、章节时间线等\n     - 视频：除摘要外，还包含使用场景等（未来会支持切分视频，递归存储子文件）\n\n\n## 核心组件\n\n### BaseParser (`base_parser.py`)\n所有解析器的抽象基类，定义了解析器的标准接口：\n\n```python\nclass BaseParser(ABC):\n    @abstractmethod\n    async def parse(self, source: Union[str, Path], instruction: str = \"\", **kwargs) -> ParseResult:\n        \"\"\"从文件路径或内容字符串解析文档\"\"\"\n        pass\n    \n    @abstractmethod\n    async def parse_content(self, content: str, source_path: Optional[str] = None, instruction: str = \"\", **kwargs) -> ParseResult:\n        \"\"\"直接解析文档内容\"\"\"\n        pass\n    \n    @property\n    @abstractmethod\n    def supported_extensions(self) -> List[str]:\n        \"\"\"支持的文件扩展名列表\"\"\"\n        pass\n```\n\n### ParserRegistry (`registry.py`)\n解析器注册表，提供自动解析器选择和注册机制：\n\n```python\nclass ParserRegistry:\n    def __init__(self, register_optional: bool = True):\n        \"\"\"初始化注册表并注册默认解析器\"\"\"\n        self._parsers: Dict[str, BaseParser] = {}\n        self._extension_map: Dict[str, str] = {}\n        \n        # 注册核心解析器\n        self.register(\"text\", TextParser())\n        self.register(\"markdown\", MarkdownParser())\n        self.register(\"pdf\", PDFParser())\n        self.register(\"html\", HTMLParser())\n        self.register(\"code\", CodeRepositoryParser())\n    \n    def get_parser_for_file(self, path: Union[str, Path]) -> Optional[BaseParser]:\n        \"\"\"根据文件扩展名获取合适的解析器\"\"\"\n        pass\n    \n    def register_custom(self, handler: \"CustomParserProtocol\", extensions: Optional[List[str]] = None, name: Optional[str] = None):\n        \"\"\"注册自定义解析器（协议方式）\"\"\"\n        pass\n```\n\n### TreeBuilder (`tree_builder.py`)\n树构建器，负责将临时目录移动到 AGFS 并入队语义处理：\n\n```python\nclass TreeBuilder:\n    async def finalize_from_temp(\n        self,\n        temp_dir_path: str,\n        scope: str,\n        base_uri: Optional[str] = None,\n        source_path: Optional[str] = None,\n        source_format: Optional[str] = None,\n    ) -> \"BuildingTree\":\n        \"\"\"\n        从临时目录最终化树结构：\n        1. 移动文件到 AGFS\n        2. 入队到 SemanticQueue（自底向上处理）\n        3. 扫描创建 Resource 对象\n        \"\"\"\n        pass\n```\n\n### 资源类型\n解析系统使用统一的 Resource 类型。\n\n## 使用示例\n\n### 基本使用\n\n```python\nfrom openviking.parse.parsers.markdown import MarkdownParser\nfrom openviking.parse.registry import get_registry\n\n# 方式1：直接使用解析器\nparser = MarkdownParser()\nresult = await parser.parse(\"document.md\")\n\n# 方式2：通过注册表自动选择\nregistry = get_registry()\nresult = await registry.parse(\"document.pdf\")  # 自动选择 PDFParser\n```\n\n### 自定义解析器\n\n```python\nfrom openviking.parse.parsers.base_parser import BaseParser\nfrom openviking.parse.base import ParseResult, ResourceNode, NodeType, create_parse_result\n\nclass CustomParser(BaseParser):\n    @property\n    def supported_extensions(self) -> List[str]:\n        return [\".xyz\"]\n    \n    async def parse(self, source: Union[str, Path], instruction: str = \"\", **kwargs) -> ParseResult:\n        content = self._read_file(source)\n        root = ResourceNode(type=NodeType.ROOT, title=\"Custom Document\")\n        return create_parse_result(root=root, source_path=str(source), source_format=\"custom\")\n\n# 注册自定义解析器\nregistry = get_registry()\nregistry.register(\"custom\", CustomParser())\n```\n\n### 协议方式扩展\n\n```python\nfrom openviking.parse.custom import CustomParserProtocol\nfrom typing import List\n\nclass MyParser:\n    @property\n    def supported_extensions(self) -> List[str]:\n        return [\".myformat\"]\n    \n    def can_handle(self, source) -> bool:\n        return str(source).endswith(\".myformat\")\n    \n    async def parse(self, source, **kwargs):\n        # 实现解析逻辑\n        pass\n\n# 注册（自动包装为 BaseParser）\nregistry.register_custom(MyParser(), name=\"my_parser\")\n```\n\n## 扩展指南\n\n### 1. 继承 BaseParser（推荐）\n适合需要完整控制解析流程的场景：\n\n```python\nfrom openviking.parse.parsers.base_parser import BaseParser\n\nclass MyParser(BaseParser):\n    @property\n    def supported_extensions(self) -> List[str]:\n        return [\".myformat\"]\n    \n    async def parse(self, source, instruction=\"\", **kwargs):\n        # 实现三阶段解析\n        # 1. 解析原始内容\n        # 2. 生成 L0/L1\n        # 3. 写入临时目录\n        pass\n    \n    async def parse_content(self, content, source_path=None, instruction=\"\", **kwargs):\n        # 类似实现\n        pass\n```\n\n### 2. 实现 CustomParserProtocol\n适合已有解析逻辑，需要快速集成：\n\n```python\nfrom openviking.parse.custom import CustomParserProtocol\n\nclass ExistingParser:\n    def parse_file(self, path):\n        # 现有解析逻辑\n        pass\n\n# 适配器模式\nclass Adapter(CustomParserProtocol):\n    def __init__(self, existing_parser):\n        self.parser = existing_parser\n    \n    @property\n    def supported_extensions(self):\n        return [\".existing\"]\n    \n    def can_handle(self, source):\n        return True\n    \n    async def parse(self, source, **kwargs):\n        result = self.parser.parse_file(source)\n        # 转换为 ParseResult\n        pass\n```\n\n### 3. 回调函数方式\n适合简单转换场景：\n\n```python\nfrom openviking.parse.registry import ParserRegistry\n\nasync def simple_parser(source, **kwargs):\n    content = Path(source).read_text()\n    # 简单处理\n    return create_parse_result(...)\n\nregistry = get_registry()\nregistry.register_callback(\".simple\", simple_parser, name=\"simple_parser\")\n```\n\n## 设计原则\n\n### 1. 解析与语义分离原则\n- 解析器完成：解析 + 文件/目录创建（零 LLM 调用）\n- 语义生成：异步 SemanticQueue 处理（自底向上）\n- TreeBuilder 只负责文件移动和入队\n- 减少解析阻塞，降低内存压力\n\n### 2. 异步语义生成\n- Parser 输出临时目录后即可返回\n- SemanticQueue 后台处理语义信息生成\n- 支持并发文件 summary 生成\n- 直接向量化写入，不经过 EmbeddingQueue\n\n### 3. 混合目录结构\n- 一个目录下可同时包含文件和子目录\n- 章节有子章节时，直接内容保存为同名文件\n- 灵活的内容组织，符合自然文档结构\n\n### 4. 临时目录架构\n- 每个解析器在临时目录中构建完整结构\n- TreeBuilder 只负责移动和入队\n- 支持并发解析，避免内存冲突\n\n### 5. 统一 Markdown 处理\n- 所有文档格式先转成 Markdown\n- 统一通过 MarkdownParser 处理结构\n- 保证一致的解析质量和输出格式\n\n### 6. 轻量级索引\n- Context 对象不存储内容，只存 URI 和元数据\n- 内容通过 `get_abstract()` / `get_overview()` / `get_detail()` 按需加载\n- 加载后缓存在内存中，避免重复读取\n\n## 存储结构\n\n### 最终 AGFS 结构\n\n混合目录结构示例（章节有子章节时，小章节合并）：\n\n```\nviking://resources/Python_异步编程指南/\n├── .abstract.md                              #

    "content": "# 代码解析方案 (Code Parser)\n\nOpenViking 通过 **Code Parser** 模块实现对代码仓库的整体解析与理解。与普通文档的拆解式处理不同，代码解析采用了基于目录结构的整体映射策略，旨在保持代码项目的完整上下文。\n\n## 概览\n\n| 特性 | 策略 | 说明 |\n|------|------|------|\n| **解析粒度** | 文件级 | 不进行 Chunking 拆分，保持单文件完整性 |\n| **目录映射** | 1:1 映射 | 本地目录结构直接映射为 Viking URI 路径 |\n| **处理模式** | 异步处理 | Parser 负责搬运，SemanticProcessor 负责理解 |\n| **元数据** | 自动提取 | 提取语言、依赖、符号定义等基础信息 |\n\n## 核心设计思考\n\n代码仓库作为一种特殊的资源类型，具有以下显著特征，这些特征直接决定了我们的技术方案：\n\n1.  **文件粒度适中**：大多数代码文件（KB 级）都在大模型上下文窗口范围内（<10k tokens），无需像长文档那样进行物理切分。\n2.  **结构即语义**：代码的目录结构（Directory Structure）本身就蕴含了模块划分、层级依赖等重要架构信息，必须严格保留。\n3.  **高频迭代**：代码变动频繁，系统需支持增量更新，避免重复索引未变动的文件。\n4.  **元数据丰富**：代码中的注释、DocString、Import 语句等包含了高密度的语义信息。\n\n## 上下文映射体系\n\n我们将代码仓库映射到 OpenViking 的标准分层描述体系中。\n\n### 1. Viking URI 映射\n\n假设用户导入了 `OpenViking` 仓库：\n\n```python\nclient.add_resource(\n    \"https://github.com/volcengine/OpenViking\",\n    target=\"viking://resources/github/volcengine/OpenViking\"\n)\n```\n\n系统将生成如下标准化的目录树结构，能够完整体现深层级的文件路径：\n\n```text\nviking://resources/github/volcengine/OpenViking/\n├── .abstract.md        # L0: 项目级摘要\n├── .overview.md        # L1: 项目级概览\n├── docs/\n│   ├── .abstract.md\n│   ├── .overview.md\n│   ├── zh/...\n│   └── en/...\n├── src/\n│   ├── .abstract.md\n│   ├── .overview.md\n│   └── index/          # 深层目录结构\n│       ├── .abstract.md\n│       ├── .overview.md\n│       └── index/      # 更深层的子模块\n│           ├── .abstract.md\n│           ├── .overview.md\n│           ├── index_engine.cpp    # L2: 具体代码文件（C++）\n│           └── ...\n└── openviking/\n    ├── .abstract.md\n    ├── .overview.md\n    └── ...\n```\n\n在这颗目录树中，每一层目录都会有一个 `.abstract.md` 文件和 `.overview.md` 文件：\n*   `.abstract.md`：目录的摘要，介绍本目录的功能和在项目中的作用。\n*   `.overview.md`：目录的概览，介绍本目录的文件结构、关键实体的位置等。\n\n### 2. 语义层级 (Context Layers)\n\n*   **L0 (Abstract)**：目录的简短功能描述，用于快速检索。\n*   **L1 (Overview)**：目录的详细概览，包含文件结构分析、关键类/函数索引。\n*   **L2 (Detail)**：原始代码文件内容。对于代码文件，我们**不进行拆分**，直接存储完整内容。\n\n## 数据处理原则\n\n1. 本方案对于任意编程语言的代码仓库均适用，不应该特殊处理任意编程语言的差异性，需要考虑策略足够通用。\n2. 对于代码仓库中的文档，除了图片以外，不要让大模型处理文本以外的其他模态内容，如视频、音频等。\n   - **说明**：\".md\"、\".txt\"、\".rst\" 等纯文本格式的文档文件**会被处理**，因为它们属于\"文本内容\"\n   - **排除**：视频（.mp4, .mov, .avi 等）、音频（.mp3, .wav, .m4a 等）等非文本格式**不会被处理**\n3. 可以忽略代码仓库中的隐藏文件，如 .git 文件夹下面的内容，__pycache__ 文件夹下面的内容等。\n4. 对于代码仓库中的符号链接，我们应当忽略并记录其目标路径，而不是直接解析符号链接。\n5. 对于代码仓库中的子目录，我们应当递归地处理，确保所有包含代码的目录，都被正确映射到 Viking URI 路径。\n\n## 技术实现方案\n\n### 1. 仓库识别与拉取\n\n扩展 `URLTypeDetector` 以支持代码仓库识别：\n\n*   **识别逻辑**：检测 URL 是否为 GitHub/GitLab 一级仓库地址（如 `https://github.com/org/repo` 或 `*.git`）。\n*   **拉取策略**：\n    *   **Git Clone**：优先使用 `git clone --depth 1` 进行浅克隆，速度最快。\n    *   **Zip Download**：作为降级方案，下载 `main.zip` 或 `master.zip`。\n*   **过滤机制**：内置过滤规则，自动忽略 `.git`, `.idea`, `__pycache__`, `node_modules` 等非代码资源。\n\n### 2. 解析流程 (CodeRepositoryParser)\n\n解析器遵循 V5.0 的异步处理架构：\n\n1.  **物理搬运 (Parser Phase)**：\n    *   将拉取到的代码仓库（经过过滤）完整上传到 `viking://temp/{uuid}/` 临时目录。\n    *   在此阶段**不进行**任何 LLM 调用，确保 `add_resource` 接口能快速返回。\n    *   仅进行基础的静态分析（如文件类型识别）。\n\n2.  **异步理解 (Semantic Phase)**：\n    *   `TreeBuilder` 将临时目录移入正式路径（如 `viking://resources/...`）。\n    *   系统自动生成 `SemanticMsg` 并推入 `SemanticQueue`。\n    *   后台 `SemanticProcessor` 消费消息，遍历目录树，异步生成各级目录的 `.abstract.md` 和 `.overview.md`。\n\n### 3. 使用示例\n\n```python\n# 导入代码仓库\nclient.add_resource(\n    \"https://github.com/volcengine/OpenViking\",\n    target=\"viking://resources/github/volcengine/OpenViking\",\n    reason=\"引入 OpenViking 源码作为参考\"\n)\n\n# 搜索代码逻辑\nresults = client.find(\n    \"OpenViking 和 VikingDB 的关系是什么？\",\n    target_uri=\"viking://resources/github/volcengine/OpenViking/OpenViking/docs/zh/\"\n)\n```\n\n> 考虑到当前性能不佳，可以用小一点的仓库测试：https://github.com/msgpack/msgpack-python\n\n## 实现细节\n\n### 文件过滤规则\n\n代码解析器实现了以下过滤规则：\n\n1. **隐藏目录忽略**：自动忽略 `.git`, `.idea`, `__pycache__`, `node_modules` 等非代码目录\n2. **二进制文件忽略**：跳过 `.pyc`, `.so`, `.dll`, `.exe`, `.bin` 等编译文件\n3. **媒体文件忽略**：不处理视频（.mp4, .mov, .avi 等）、音频（.mp3, .wav, .m4a 等）等非文本内容\n4. **文档文件处理**：`.md`, `.txt`, `.rst` 等纯文本格式的文档文件**会被处理**，因为它们属于\"文本内容\"\n5. **符号链接处理**：检测并跳过符号链接，记录目标路径但不解析内容\n6. **文件大小限制**：跳过大于 10MB 的文件和零字节文件\n\n### 文件类型检测\n\n解析器包含辅助方法 `_detect_file_type()` 用于检测文件类型，可返回：\n- `\"code\"`：编程语言文件（.py, .java, .js, .cpp 等）\n- `\"documentation\"`：文档文件（.md, .txt, .rst 等）\n- `\"other\"`：其他文本文件\n- `\"binary\"`：二进制文件（已通过 `IGNORE_EXTENSIONS` 过滤）\n\n### 测试验证\n\n包含完整的测试文件 `tests/misc/test_code_parser.py` 验证：\n- `IGNORE_DIRS` 包含所有必需的目录\n- `IGNORE_EXTENSIONS` 包含所有必需的格式\n- 符号链接处理正确实现\n- 文件类型检测逻辑准确\n\n### 优化 TODO\n- 支持采用更轻量的模型进行文件摘要，加快处理速度\n- 设计长任务的追踪机制，帮助观测任务队列中的任务归属，提供处理任务的统计信息\n- 支持增量解析，只解析新增或变动的文件，避免重复解析已处理文件\n- 大幅提升端到端的处理性能！\n\n## 相关文档\n\n*   [上下文类型](docs/zh/concepts/context-types.md)\n*   [Viking URI](docs/zh/concepts/viking-uri.md)\n*   [上下文层级](docs/zh/concepts/context-layers.md)\n"

Return ``ParseResult`` so that ``TreeBuilder.finalize_from_temp``\n   can move the content to AGFS and enqueue semantic processing.\n\"\"\"\n\nimport time\nfrom pathlib import Path, PurePosixPath\nfrom typing import TYPE_CHECKING, Any, Dict, List, Optional, Union\n\nfrom openviking.parse.base import (\n    NodeType,\n    ParseResult,\n    ResourceNode,\n    create_parse_result,\n)\nfrom openviking.parse.parsers.base_parser import BaseParser\nfrom openviking.parse.parsers.media.constants import MEDIA_EXTENSIONS\nfrom openviking_cli.utils.logger import get_logger\n\nif TYPE_CHECKING:\n    from openviking.parse.directory_scan import ClassifiedFile\n    from openviking.parse.registry import ParserRegistry\n\nlogger = get_logger(__name__)\n\n\nclass DirectoryParser(BaseParser):\n    \"\"\"\n    Parser for local directories.\n\n    Scans the directory, delegates each file to its registered parser via\n    ``parser.parse()``, and merges all results into a single VikingFS temp.\n    Files without a dedicated parser are written directly.\n\n    The resulting ``ParseResult.temp_dir_path`` is consumed by\n    ``TreeBuilder.finalize_from_temp`` exactly like any other parser.\n    \"\"\"\n\n    @property\n    def supported_extensions(self) -> List[str]:\n        # Directories have no file extension; routing is handled\n        # by ``is_dir()`` checks in the registry / media processor.\n        return []\n\n    def can_parse(self, path: Union[str, Path]) -> bool:  # type: ignore[override]\n        \"\"\"Return *True* when *path* is an existing directory.\"\"\"\n        return Path(path).is_dir()\n\n    # ------------------------------------------------------------------\n    # Main entry point\n    # ------------------------------------------------------------------\n\n    async def parse(\n        self,\n        source: Union[str, Path],\n        instruction: str = \"\",\n        **kwargs,\n    ) -> ParseResult:\n        \"\"\"Parse a local directory.\n\n        Args:\n            source: Path to the directory.\n            instruction: Processing instruction (forwarded where applicable).\n            **kwargs: Extra options forwarded to ``scan_directory``:\n                ``strict``, ``ignore_dirs``, ``include``, ``exclude``,\n                ``directly_upload_media``.\n\n        Returns:\n            ``ParseResult`` with ``temp_dir_path`` pointing to VikingFS temp.\n        \"\"\"\n        start_time = time.time()\n        source_path = Path(source).resolve()\n\n        if not source_path.is_dir():\n            raise NotADirectoryError(f\"Not a directory: {source_path}\")\n\n        dir_name = source_path.name\n        warnings: List[str] = []\n\n        try:\n            # ── Phase 1: scan directory ───────────────────────────────\n            from openviking.parse.directory_scan import scan_directory\n            from openviking.parse.registry import get_registry\n\n            registry = get_registry()\n\n            scan_result = scan_directory(\n                root=str(source_path),\n                registry=registry,\n                strict=kwargs.get(\"strict\", False),\n                ignore_dirs=kwargs.get(\"ignore_dirs\"),\n                include=kwargs.get(\"include\"),\n                exclude=kwargs.get(\"exclude\"),\n            )\n            directly_upload_media = kwargs.get(\"directly_upload_media\", True)\n            preserve_structure = kwargs.get(\"preserve_structure\")\n            if preserve_structure is None:\n                # Fall back to config default\n                try:\n                    from openviking_cli.utils.config.open_viking_config import (\n                        get_openviking_config,\n                    )\n\n                    preserve_structure = get_openviking_config().directory.preserve_structure\n                except Exception:\n                    preserve_structure = True\n            processable_files = scan_result.all_processable_files()\n            warnings.extend(scan_result.warnings)\n\n            viking_fs = self._get_viking_fs()\n            temp_uri = self._create_temp_uri()\n            target_uri = f\"{temp_uri}/{dir_name}\"\n            await viking_fs.mkdir(temp_uri, exist_ok=True)\n            await viking_fs.mkdir(target_uri, exist_ok=True)\n\n            if not processable_files:\n                root = ResourceNode(\n                    type=NodeType.ROOT,\n                    title=dir_name,\n                    meta={\"file_count\": 0, \"type\": \"directory\"},\n                )\n                result = create_parse_result(\n                    root=root,\n                    source_path=str(source_path),\n                    source_format=\"directory\",\n                    parser_name=\"DirectoryParser\",\n                    parse_time=time.time() -

When present, extract relevant tool/skill memories.\n  - **Exhaustive extraction**: A single message may contain multiple independent facts.\n    Extract EACH as a separate memory item. Do not merge unrelated facts into one summary.\n    Count the distinct factual claims in each message and ensure each one is captured.\n  - **Detail preservation**: Always preserve specific proper nouns, parameter names, numeric\n    values, version numbers, and technical terms verbatim. The value of a memory lies in its\n    specificity. A memory that says \"solved problem X using method Y\" is useful; a memory\n    that says \"handled problem X\" is nearly useless because it loses the solution.\n  - **High recall**: When uncertain whether something is worth extracting, extract it.\n    The downstream deduplication system handles redundancy. Missing a valuable memory is\n    worse than creating a slightly redundant one.\n  - **Temporal precision**: Never use relative time expressions (\"today\", \"recently\",\n    \"last week\") in memory content. Convert to absolute references or omit the time\n    if unknown. Memories persist indefinitely; relative time becomes meaningless.\n\n  {% if feedback %}\n  ## User Feedback\n  {{ feedback }}\n  {% endif %}\n\n  # Memory Extraction Criteria\n\n  ## What is worth remembering?\n  - ✅ **Personalized information**: Information specific to this user, not general domain knowledge\n  - ✅ **Long-term validity**: Information that will still be useful in future sessions\n  - ✅ **Specific and clear**: Has concrete details, not vague generalizations\n\n  ## What is NOT worth remembering?\n  - ❌ **General domain knowledge**: Information true for everyone, not specific to this user.\n    Example: \"Redis is an in-memory database\" is general knowledge.\n    But \"User's team uses Redis with 10-minute TTL for product cache\" IS personalized.\n  - ❌ **Content-free utterances**: Pure greetings, acknowledgments, or filler with zero\n    informational content (\"Hello\", \"Thanks\", \"OK\").\n  - ❌ **Completely vague statements**: No concrete details at all.\n    \"User has some concerns\" (what concerns? about what?)\n\n  # Memory Classification\n\n  ## Core Decision Logic\n\n  When choosing a category, first ask yourself: What is this information mainly about?\n\n  | Question | Answer | Category |\n  |----------|--------|----------|\n  | Who is the user? | Identity, attributes | profile |\n  | What does the user prefer? | Preferences, habits | preferences |\n  | What is this thing? | Person, project, organization | entities |\n  | What happened? | Decision, milestone | events |\n  | How was it solved? | Problem + solution | cases |\n  | What is the process? | Reusable steps | patterns |\n  | How to use a tool? | Tool optimization, parameters | tools |\n  | How to execute a skill? | Workflow, strategy | skills |\n\n  ## Precise Definition of Each Category\n\n  **profile** - User identity (static attributes)\n  - Core: Describes \"who the user is\"\n  - Characteristics: Relatively stable personal attributes\n  - Test: Can it start with \"User is...\"\n\n  **preferences** - User preferences (tendency choices)\n  - Core: Describes \"user tends to/habits\"\n  - Characteristics: Changeable choices, styles\n  - Test: Can it be described as \"User prefers/likes...\"\n\n  ### Preference Granularity (Important)\n  - Cover all preference types mentioned by the user.\n  - Facets are open-ended and semantic, not a fixed taxonomy.\n  - The facet examples in this prompt are illustrative, not exhaustive.\n  - For category `preferences`, each memory item should represent one independently\n    updatable preference unit (single facet).\n  - Do NOT mix unrelated preference facets in one memory item.\n    Examples of different facets: food, commute, schedule, tools, music, study habits.\n  - If a new/rare facet appears, create a new facet memory instead of forcing it into existing examples.\n  - Do not drop a valid preference just because its facet is not listed in examples.\n  - If the conversation contains multiple facets, output multiple `preferences` items.\n  - This granularity is required so future updates/conflicts can affect only the\n    relevant memory without damaging unrelated preferences.\n\n  **entities** - Entities (named things with attributes)\n  - Core: Describes \"what is this named thing and what are its attributes\"\n  - Characteristics: Named entities that exist independently of the user's preferences\n    (people, projects, organizations, systems, teams, technologies-as-systems)\n  - Test: Does it describe a THING (not a preference, not an event, not a problem)?\n  - Includes: project descriptions, system architectures, team compositions,\n    organization structures, named tools/platforms with their configurations\n  - Note: \"Our system uses tech stack X\" describes the SYSTEM → entities.\n    \"I prefer using tool X\" describes USER preference → preferences.\n\n  **events** - Events (time-bound activities: past, present, or future)\n  - Core: Describes \"what happened\", \"what is happening\", or \"what is planned\"\n  - Characteristics: Has a time dimension (creation time, occurrence time, or deadline);\n    covers completed, ongoing, and planned activities\n  - Test: Can it be described as \"XXX did/is doing/plans to do...\"\n  - Includes: past decisions, completed activities, ongoing activities\n    (e.g., currently reading a book), planned future activities, deadlines,\n    goals with timeframes\n  - Note: An ongoing activity like \"currently reading book X\" is an event\n    (time-bound), not a preference. A plan like \"tonight will optimize X\"\n    is also an event (has creation time and intended execution time).\n\n  **cases** - Cases (problem → cause/solution/outcome)\n  - Core: Describes a specific problem and how it was diagnosed, caused, or resolved\n  - Characteristics: Contains a concrete problem description AND at least one of:\n    root cause, solution method, workaround, or outcome/impact\n  - Test: Does it follow a \"problem → cause/solution/outcome\" structure?\n  - Note: Even if the problem seems minor or one-time, extract it if both the\n    problem and its resolution/cause are stated. The specific details\n    (error messages, parameter values, method names) are the most valuable part.\n\n  **patterns** - Patterns (reusable processes)\n  - Core: Describes \"what process to follow in what situation\"\n  - Characteristics: Reusable across multiple scenarios\n  - Test: Can it be used for \"similar situations\"\n\n  **tools** - Tool usage memories (optimization insights)\n  - Core: Describes \"how to best use a specific tool\"\n  - Characteristics: Parameter optimization, success/failure patterns\n  - Test: Does it contain tool-specific usage insights\n  - **Source**: Extracted from [ToolCall] records in the conversation\n  - Examples:\n    - \"web_search works best with specific multi-word queries\"\n    - \"read_file should check file size first for large files\"\n    - \"execute_code timeout can be avoided by splitting large scripts\"\n\n  **skills** - Skill execution memories (workflow insights)\n  - Core: Describes \"how to best execute a specific skill\"\n  - Characteristics: Process optimization, context adaptation, multi-step workflows\n  - Test: Does it contain skill-specific execution strategies\n  - **Source**: Analyze the full conversation context to identify skill usage patterns. Skills may involve multiple internal tool calls (shell commands, file operations, etc.) that are NOT shown in [ToolCall] records. You must infer skill execution from the conversation flow.\n  - Examples:\n    - \"create_ppt works best when collecting materials first\"\n    - \"analyze_code should start with understanding project structure\"\n    - \"write_document benefits from outline-first approach\"\n\n  ## Common Confusion Clarification\n\n  - \"Plan to do X\" → events (action, not entity)\n  - \"Project X status: Y\" → entities (describes entity)\n  - \"User prefers X\" → preferences (not profile)\n  - \"Encountered problem A, used solution B\" → cases (not events)\n  - \"General process for handling certain problems\" → patterns (not cases)\n  - \"We use tool/platform/framework X for purpose Y\" → entities (describes a system/setup)\n  - \"I prefer/like using tool X\" → preferences (personal choice)\n  - \"Currently reading/learning/studying X\" → events (ongoing time-bound activity)\n  - \"Bug: misconfigured parameter X caused issue Y\" → cases (problem + cause)\n  - \"User's daily routine: do X in morning, Y in afternoon\" → preferences (habitual pattern)\n  - \"Colleague/teammate X is responsible for Y\" → entities (describes a person)\n\n  # Three-Level Structure\n\n  Each memory contains three levels, each serving a purpose:\n\n  **abstract (L0)**: Index layer, plain text one-liner\n  - Merge types (preferences/entities/profile/patterns): `[Merge key]: [Description]`\n    - preferences: `Python code style: No type hints, concise and direct`\n    - entities: `OpenViking project: AI Agent long-term memory management system`\n    - profile: `User basic info: AI development engineer, 3 years experience`\n    - patterns: `Teaching topic handling: Outline→Plan→Generate PPT`\n  - Independent types (events/cases): Specific description\n    - events: `Decided to refactor memory system: Simplify to 5 categories`\n    - cases: `Band not recognized → Request member/album/style details`\n\n  **overview (L1)**: Structured summary layer, organized with Markdown headings\n  - preferences: `## Preference Domain` / `## Specific Preferences`\n  - entities: `## Basic Info` / `## Core Attributes`\n  - events: `## Decision Content` / `## Reason` / `## Result`\n  - cases: `## Problem` / `## Solution`\n\n  **content (L2)**: Detailed expansion layer, free Markdown, includes background, timeline, complete narrative\n\n  # Few-shot Examples\n\n  ## profile Example (Merge type)\n  ✅ **Good**:\n  ```json\n  {\n    \"category\": \"profile\",\n    \"abstract\": \"User basic info: AI development engineer, 3 years LLM application experience\",\n    \"overview\": \"## Background Info\\\\n- Occupation: AI development engineer\\\\n- Experience: 3 years LLM application development\\\\n- Tech stack: Python, LangChain\",\n    \"content\": \"User is an AI development engineer with 3 years of LLM application development experience, mainly using Python and LangChain tech stack.

\"Create RFC document\", \"Write technical specification\"\n  - \"Extract PDF table data\", \"Merge PDF documents\"\n  - \"Build MCP server\", \"Add API tools\"\n\n  ❌ Wrong Examples:\n  - \"RFC document format specification\" (this is a resource query)\n  - \"PDF processing methods\" (this is a resource query)\n\n  **When to Query**:\n  - Task contains action verbs (create, generate, write, build, analyze, process)\n  - Need to perform specific operations\n\n  ### 2. resource (Knowledge Resources)\n\n  **Purpose**: Documents, specifications, guides, code, configurations, and other structured knowledge\n\n  **Query Style**: **Noun phrases, describing knowledge content**\n\n  ✅ Correct Examples:\n  - \"RFC document standard template\", \"API usage guide\"\n  - \"Project architecture design\", \"Code style documentation\"\n\n  ❌ Wrong Examples:\n  - \"Create RFC document\" (this is a skill query)\n  - \"How to use API\" (this is a skill query)\n\n  **When to Query**:\n  - Need reference materials, templates, specifications\n  - Need to understand knowledge, concepts, definitions\n\n  ### 3. memory (User/Agent Memory)\n\n  **Purpose**: User personalization information or Agent execution experience\n\n  **Query Style**: Distinguish by memory type\n\n  **User Memory** - \"User XX\" format:\n  ✅ Correct Examples:\n  - \"User's preferred document style\"\n  - \"User's code style habits\"\n  - \"User's project background information\"\n\n  **Agent Memory** - \"Experience executing XX\" or \"System insights about YY\":\n  ✅ Correct Examples:\n  - \"Experience executing document generation tasks\"\n  - \"Historical records of similar RFC creation\"\n  - \"System insights about document collaboration\"\n\n  ❌ Wrong Examples:\n  - \"Last execution result\" (too vague)\n  - \"Previously discussed architecture\" (too vague)\n\n  **When to Query**:\n  - Need personalized customization (user memory)\n  - Need to learn from historical experience (agent memory)\n\n  ## Analysis Method\n\n  ### Step 1: Identify Task Type\n\n  **Operational Tasks** (containing actions):\n  - Characteristics: Verbs like create, generate, write, build, transform, calculate, analyze, process\n  - Typical context combination: `skill + resource + memory`\n\n  Examples:\n  | User Task | Required Context |\n  |-----------|------------------|\n  | \"Create an RFC document\" | skill: \"Create RFC document\"<br>resource: \"RFC document standard template\"<br>memory: \"User's preferred document style\" |\n  | \"Merge three PDFs\" | skill: \"Merge PDF documents\"<br>memory: \"User's file processing preferences\" |\n\n  **Informational Tasks** (acquiring knowledge):\n  - Characteristics: What is, how to understand, why, concept explanation, etc.\n  - Typical context combination: `resource + memory`\n\n  Examples:\n  | User Task | Required Context |\n  |-----------|------------------|\n  | \"What is the standard format for RFC documents\" | resource: \"RFC document standard format specification\"<br>memory: \"System insights about RFC specifications\" |\n\n  **Conversational Tasks** (small talk):\n  - Characteristics: Greetings, small talk, confirmation of understanding, etc.\n  - Usually no query needed\n\n  ### Step 2: Check Context Coverage\n\n  Analyze whether the session context (summary + recent conversation) already contains the information needed to complete the task:\n\n  - **Fully covered**: Skip queries for that type\n  - **Partially covered**: Generate supplementary queries\n  - **Not covered**: Generate complete queries\n\n  **Note**: Only skip information that has been **explicitly and in detail** discussed in the context.\n\n  ### Step 3: Generate Queries\n\n  **Important Principles**:\n\n  1. **Don't over-transform**:\n     - ❌ Don't convert \"Create XX\" to \"XX format/specification\"\n     - ✅ Skill queries for operational tasks must maintain action characteristics\n\n  2. **Multi-type combination**:\n     - A task may require multiple context types\n     - Operational tasks typically need: skill (execution) + resource (reference) + memory (preference/experience)\n\n  3. **Multiple queries per type**:\n     - Can generate multiple queries for the same type\n     - Maximum 5 queries\n\n  4. **Queries should be concise and specific**:\n     - Queries should be short, specific, and retrievable\n     - Avoid lengthy descriptions\n\n  5. **Priority setting**:\n     - 1 = Highest priority (core requirement)\n     - 3 = Medium priority (helpful)\n     - 5 = Lowest priority (optional)\n\n  ## Output Format\n\n  ```json\n  {\n      \"reasoning\": \"1. Task type (operational/informational/conversational); 2. What context is needed (skill/resource/memory); 3. What is already in context; 4. What is missing and needs to be queried\",\n      \"queries\": [\n          {\n              \"query\": \"Specific query text (following the style of the corresponding type)\",\n              \"context_type\": \"skill|resource|memory\",\n              \"intent\": \"Purpose of the query\",\n              \"priority\": 1-5\n          }\n      ]\n  }\n  ```\n\n  **Example Output**:\n\n  Input: \"Create an RFC document\"\n  ```json\n  {\n      \"reasoning\": \"1.

    "content": "# Storage Observers\n\n## Overview\n\nThe `observers` module provides observability capabilities for the OpenViking storage system. Observers allow monitoring and reporting the status of various storage components in real-time.\n\n## Architecture\n\n### BaseObserver\n\nAll observers inherit from `BaseObserver`, which defines the common interface:\n\n```python\nfrom openviking.storage.observers import BaseObserver\n\nclass MyObserver(BaseObserver):\n    def get_status_table(self) -> str:\n        \"\"\"Format status information as a string.\"\"\"\n\n    def is_healthy(self) -> bool:\n        \"\"\"Check if observed system is healthy.\"\"\"\n\n    def has_errors(self) -> bool:\n        \"\"\"Check if observed system has any errors.\"\"\"\n```\n\n### Available Observers\n\n#### QueueObserver\n\nMonitors queue system status (Embedding, Semantic, and custom queues).\n\n**Location:** `openviking/storage/observers/queue_observer.py`\n\n**Usage:**\n\n```python\nimport openviking as ov\n\nclient = ov.OpenViking(path=\"./data\")\nprint(client.observer.queue)\n# Output:\n#     Queue  Pending  In Progress  Processed  Errors  Total\n# Embedding        5            2          100       0      107\n#  Semantic        3            1           95       1       99\n#     TOTAL        8            3          195       1      206\n```\n\n#### VikingDBObserver\n\nMonitors VikingDB collection status (index count and vector count per collection).\n\n**Location:** `openviking/storage/observers/vikingdb_observer.py`\n\n**Usage:**\n\n```python\nimport openviking as ov\n\nclient = ov.OpenViking(path=\"./data\")\nprint(client.observer.vikingdb())\n# Output:\n#    Collection  Index Count  Vector Count Status\n#    context            1            69     OK\n#     TOTAL             1            69\n```\n\n## Best Practices\n\n1. **Use `get_status_table()` for human-readable output**: Provides clean, formatted tables\n2. **Check the table output**: Look at \"Errors\" column to detect issues early\n3. **Use with sync or async client**: Works seamlessly with both `OpenViking` and `AsyncOpenViking`\n\n## See Also\n\n- [QueueFS Documentation](../queuefs/README.md)\n- [Storage Documentation](../../docs/OpenViking存储.md)\n- [API Documentation](../../docs/OpenViking接口文档.md)\n"

\"2026-02-07T23:59:59\"\n}\n```\n\n#### 4. `geo_range` - 地理范围查询（geo_point）\n\n`geo_point` 字段写入格式为 `\"longitude,latitude\"`，其中：\n- `longitude` ∈ (-180, 180)\n- `latitude` ∈ (-90, 90)\n\n`radius` 支持 `m` 和 `km` 单位。\n\n```python\nfilters = {\n    \"op\": \"geo_range\",\n    \"field\": \"f_geo_point\",\n    \"center\": \"116.412138,39.914912\",\n    \"radius\": \"10km\"\n}\n```\n\n### 复杂过滤示例\n\n```python\n# 示例1: 查找特定类别且高优先级的文档\nresult = collection.search_by_vector(\n    index_name=\"test_index\",\n    dense_vector=query_vector,\n    filters={\n        \"op\": \"must\",\n        \"field\": \"category\",\n        \"conds\": [\"tech\", \"science\"]\n    },\n    limit=10\n)\n\n# 示例2: 查找特定分数范围的文档\nresult = collection.search_by_vector(\n    index_name=\"test_index\",\n    dense_vector=query_vector,\n    filters={\n        \"op\": \"range\",\n        \"field\": \"score\",\n        \"gte\": 0.7,\n        \"lte\": 0.95\n    },\n    limit=10\n)\n```\n\n## 最佳实践\n\n### 1. 选择合适的存储模式\n\n- **内存模式**：适合临时数据、测试环境、性能敏感场景\n- **持久化模式**：适合生产环境、数据需要持久保存的场景\n\n### 2. 索引设计\n\n- 为常用的过滤字段创建标量索引\n- 根据向量类型选择合适的距离度量（IP 或 L2）\n- 归一化向量时使用 IP 距离\n\n### 3. 性能优化\n\n- 使用批量操作减少 I/O 次数\n- 合理设置 limit 和 offset 进行分页\n- 避免频繁的 delete_all 操作\n- 对于大数据集，使用过滤条件缩小搜索范围\n\n### 4. 资源管理\n\n- 使用完毕后调用 `collection.close()` 释放资源\n- 合理设置 TTL 自动清理过期数据\n- 定期监控索引大小和内存使用\n\n## API 参考\n\n### Collection 方法\n\n| 方法

    "content": "# VectorDB Adapter 接入指南（新增第三方后端）\n\n本指南说明如何在 `openviking/storage/vectordb_adapters` 下新增一个第三方向量库后端，并接入 OpenViking 现有检索链路。\n\n---\n\n## 1. 目标与范围\n\n### 目标\n- 以最小改动新增一个向量库后端。\n- 保持上层业务接口不变（`find/search` 等无需改调用方式）。\n- 将后端差异封装在 Adapter 层，不泄漏到业务层。\n\n### 非目标\n- 不改上层语义检索策略（租户、目录层级、召回策略）。\n- 不增加新的对外 API 协议。\n\n---\n\n## 2. 架构位置与职责\n\n当前分层职责如下：\n\n1. **上层语义层（OpenViking 业务）**  \n   面向语义接口，不关心后端协议差异。\n\n2. **通用向量存储层（Store/Backend）**  \n   提供统一查询、写入、删除、计数能力。\n\n3. **Adapter 层（本目录）**  \n   负责把统一能力映射到具体后端实现（local/http/volcengine/vikingdb/thirdparty）。\n\n新增后端时，主要只改第 3 层。\n\n---\n\n## 3. 接入前提\n\n在开始前，请确认：\n\n- 你已拿到第三方后端的：\n  - 集合管理 API（查/建/删集合）\n  - 数据 API（upsert/get/delete/search/aggregate）\n- 你已明确该后端的：\n  - 认证方式（AK/SK、token、header）\n  - 过滤语法能力（是否支持 must/range/and/or）\n  - 索引参数约束（dense/sparse、距离度量、索引类型）\n\n---\n\n## 4. 接入步骤\n\n## Step 1：新增 Adapter 文件\n\n在目录下新增文件，例如：\n\n- `openviking/storage/vectordb_adapters/thirdparty_adapter.py`\n\n定义类：\n\n- `ThirdPartyCollectionAdapter(CollectionAdapter)`\n\n基类位于：\n\n- `openviking/storage/vectordb_adapters/base.py`\n\n---\n\n## Step 2：实现最小必需方法\n\n你需要实现以下方法：\n\n1. `from_config(cls, config)`  \n   - 从 `VectorDBBackendConfig` 读取后端配置并构造 adapter。\n   - collection 名建议使用 `config.name or \"context\"`。\n\n2. `_load_existing_collection_if_needed(self)`  \n   - 懒加载已存在 collection handle。\n   - 若不存在，保持 `_collection is None`。\n\n3. `_create_backend_collection(self, meta)`  \n   - 按传入 schema 创建 collection 并返回 handle。\n\n---\n\n## Step 3：按后端能力补充可选 Hook\n\n如后端有差异，可重写：\n\n- `_sanitize_scalar_index_fields(...)`\n- `_build_default_index_meta(...)`\n\n目的：把后端特性差异收敛在 adapter 内。\n\n---\n\n## Step 4：注册到 Factory\n\n编辑：\n\n- `openviking/storage/vectordb_adapters/factory.py`\n\n在 `_ADAPTER_REGISTRY` 增加映射，例如：\n\n```python\n\"thirdparty\": ThirdPartyCollectionAdapter\n```\n\n这样 `create_collection_adapter(config)` 会自动路由到你的实现。\n\n---\n\n## Step 5：补充配置模型\n\n确保配置中可声明新 backend（如 `backend: thirdparty`）及其专属字段（endpoint/auth/region 等）。\n\n原则：\n- `create_collection` 时使用配置中的 name 绑定 collection。\n- 后续操作默认绑定，不需要每次传 collection_name。\n\n---\n\n## Step 6：配置 ov.conf\n\n对于没有提交到仓库，或者在第三方仓库的 Adapter，可以通过配置 `backend` 为完整的类路径来动态加载。\n同时，可以使用 `custom_params` 字段传递自定义参数。\n\n在 `ov.conf`  中添加如下配置：\n\n```json\n{\n  \"storage\": {\n    \"vectordb\": {\n      \"backend\": \"tests.storage.mock_backend.MockCollectionAdapter\",\n      \"name\": \"mock_test_collection\",\n      \"custom_params\": {\n        \"custom_param1\": \"val1\",\n        \"custom_param2\": 123\n      }\n    }\n  }\n}\n```\n\n注意：\n1. `backend`: 填写 Adapter 类的完整 Python 路径（例如 `my_project.adapters.MyAdapter`）。\n2. `custom_params`: 这是一个字典，你可以放入任何自定义参数，Adapter 的 `from_config` 方法可以通过 `config.custom_params` 获取这些值。\n\n\n\n---\n\n## 5. Filter 与查询兼容规则\n\n- Adapter 需要兼容统一过滤表达。\n- 上层传入的过滤表达会经由统一编译流程进入后端查询。\n- 若第三方语法不同，请在 adapter 内做映射，不改上层调用协议。\n\n关键原则：\n- **后端 DSL 不上浮到业务层**。\n- **业务层不依赖第三方私有查询语法**。\n\n---\n\n## 6. 最小代码骨架（示例）\n\n```python\nfrom __future__ import annotations\nfrom typing import Any, Dict\n\nfrom openviking.storage.vectordb_adapters.base import CollectionAdapter\n\nclass ThirdPartyCollectionAdapter(CollectionAdapter):\n    def __init__(self, *, endpoint: str, token: str, collection_name: str):\n        super().__init__(collection_name=collection_name)\n        self.mode = \"thirdparty\"\n        self._endpoint = endpoint\n        self._token = token\n\n    @classmethod\n    def from_config(cls, config: Any):\n        if not config.thirdparty or not config.thirdparty.endpoint:\n            raise ValueError(\"ThirdParty backend requires endpoint\")\n        return cls(\n            endpoint=config.thirdparty.endpoint,\n            token=config.thirdparty.token,\n            collection_name=config.name or \"context\",\n        )\n\n    def _load_existing_collection_if_needed(self) -> None:\n        if self._collection is not None:\n            return\n        # TODO: 查询远端 collection 是否存在，存在则初始化 handle\n        # self._collection = ...\n        pass\n\n    def _create_backend_collection(self, meta: Dict[str, Any]):\n        # TODO: 调后端 create collection，并返回 collection handle\n        # return ...\n        raise NotImplementedError\n```\n\n---\n\n## 7. 测试要求（必须）\n\n至少覆盖以下场景：\n\n1. backend 工厂路由正确（能创建到新 adapter）。\n2. collection 生命周期可用（exists/create/drop）。\n3. 基础数据链路可用（upsert/get/delete/query）。\n4. count/aggregate 行为正确。\n5. filter 条件可正确生效（含组合条件）。\n\n---\n\n## 8. 常见问题与排查\n\n### Q1：启动时报 backend 不支持\n- 检查 factory 是否注册。\n- 检查配置里的 backend 字符串是否与 registry key 一致。\n\n### Q2：集合创建成功但查询为空\n- 检查 collection 绑定名是否一致。\n- 检查索引是否创建成功。\n- 检查 filter 映射是否把条件误转成空条件。\n\n### Q3：count 与 query 条数不一致\n- 检查 aggregate API 的字段命名与返回结构解析。\n- 检查 count 使用的 filter 与 query 使用的 filter 是否一致。\n\n---\n\n## 9. 验收标准\n\n当满足以下条件，即可视为接入完成：\n\n- `backend=thirdparty` 可正常初始化。\n- create 后可完成 upsert/get/query/delete/count 全流程。\n- 不改上层业务调用方式即可参与 `find/search` 检索链路。\n- 后端差异全部封装在 adapter 层。"

A tribute to Plan9.\r\n\r\n## Why AGFS?\r\n\r\nWhen coordinating multiple AI Agents in a distributed environment, agents need access to various backend services: message queues, databases, object storage, KV stores, and more. The traditional approach requires writing specialized API calls for each service, meaning agents must understand many different interfaces.\r\n\r\nThe core idea of AGFS is simple: **unify all services as file system operations**.\r\n\r\n```\r\nTraditional approach                    AGFS approach\r\n------------------------------------------------------------------\r\nredis.set(\"key\", \"value\")          ->   echo \"value\" > /kvfs/keys/mykey\r\nsqs.send_message(queue, msg)       ->   echo \"msg\" > /queuefs/q/enqueue\r\ns3.put_object(bucket, key, data)   ->   cp file /s3fs/bucket/key\r\nmysql.execute(\"SELECT ...\")        ->   echo \"SELECT ...\" > /sqlfs2/.../query\r\n```\r\n\r\nThe benefits:\r\n\r\n1. **AI understands file operations natively** - Any LLM knows how to use cat, echo, and ls. No API documentation needed.\r\n2. **Unified interface** - Operate all backends the same way, reducing cognitive overhead.\r\n3. **Composability** - Combine services using pipes, redirections, and other shell features.\r\n4. **Easy debugging** - Use ls and cat to inspect system state.\r\n\r\n## Quick Start\r\n\r\nInstall:\r\n\r\n```bash\r\ncurl -fsSL https://raw.githubusercontent.com/c4pt0r/agfs/master/install.sh | sh\r\n```\r\n\r\nOr via Docker:\r\n\r\n```bash\r\ndocker pull c4pt0r/agfs-server:latest\r\n```\r\n\r\nConnect using agfs-shell:\r\n\r\n```bash\r\n$ agfs\r\nagfs:/> ls\r\nqueuefs/  kvfs/  s3fs/  sqlfs/  heartbeatfs/  memfs/  ...\r\n```\r\n\r\n## FUSE Support\r\n\r\nAGFS can be mounted as a native filesystem on Linux using FUSE. This allows any program to interact with AGFS services using standard file operations, not just the agfs-shell.\r\n\r\n```bash\r\n# Mount AGFS to /mnt/agfs\r\nagfs-fuse --agfs-server-url http://localhost:8080 --mount /mnt/agfs\r\n\r\n# Now use standard tools\r\nls /mnt/agfs/kvfs/keys/\r\necho \"hello\" > /mnt/agfs/kvfs/keys/mykey\r\ncat /mnt/agfs/queuefs/tasks/dequeue\r\n```\r\n\r\nThis makes AGFS accessible to any application, script, or programming language that can read and write files.\r\n\r\nSee [agfs-fuse/README.md](./agfs-fuse/README.md) for installation and usage.\r\n\r\n## Examples\r\n\r\n### Key-Value Store\r\n\r\nThe simplest key-value storage. Filename is the key, content is the value:\r\n\r\n```bash\r\nagfs:/> echo \"world\" > /kvfs/keys/hello      # write\r\nagfs:/> cat /kvfs/keys/hello                  # read -> \"world\"\r\nagfs:/> ls /kvfs/keys/                        # list all keys\r\nhello\r\nagfs:/> rm /kvfs/keys/hello                   # delete\r\n```\r\n\r\n### Message Queue\r\n\r\nA message queue is abstracted as a directory containing control files:\r\n\r\n```bash\r\nagfs:/> mkdir /queuefs/tasks             # create queue\r\nagfs:/> ls /queuefs/tasks\r\nenqueue  dequeue  peek  size  clear\r\n\r\nagfs:/> echo \"job1\" > /queuefs/tasks/enqueue    # enqueue\r\n019aa869-1a20-7ca6-a77a-b081e24c0593\r\n\r\nagfs:/> cat /queuefs/tasks/size                 # check queue length\r\n1\r\n\r\nagfs:/> cat /queuefs/tasks/dequeue              # dequeue\r\n{\"id\":\"019aa869-...\",\"data\":\"job1\",\"timestamp\":\"2025-11-21T13:54:11Z\"}\r\n```\r\n\r\nThis pattern is ideal for AI Agent task distribution: one agent writes tasks to the queue, another agent reads and executes them.\r\n\r\n### SQL Database\r\n\r\nQuery databases through a Plan 9 style session interface:\r\n\r\n```bash\r\nagfs:/> cat /sqlfs2/mydb/users/schema       # view table structure\r\nagfs:/> cat /sqlfs2/mydb/users/count        # get row count\r\n\r\n# Create session, execute query, read result\r\nagfs:/> sid=$(cat /sqlfs2/mydb/users/ctl)\r\nagfs:/> echo \"SELECT * FROM users LIMIT 2\" > /sqlfs2/mydb/users/$sid/query\r\nagfs:/> cat /sqlfs2/mydb/users/$sid/result\r\n[{\"id\": 1, \"name\": \"alice\"}, {\"id\": 2, \"name\": \"bob\"}]\r\n```\r\n\r\n### Agent Heartbeat\r\n\r\nManage the liveness state of distributed agents:\r\n\r\n```bash\r\nagfs:/> mkdir /heartbeatfs/agent-1       # register agent\r\nagfs:/> touch /heartbeatfs/agent-1/keepalive   # send heartbeat\r\n\r\nagfs:/> cat /heartbeatfs/agent-1/ctl     # check status\r\nlast_heartbeat_ts: 2025-11-21T13:55:45-08:00\r\ntimeout: 30\r\nstatus: alive\r\n\r\n# After 30 seconds without a new heartbeat, the agent directory is automatically removed\r\n```\r\n\r\n### Cross-FS Operations\r\n\r\nDifferent filesystems can operate with each other:\r\n\r\n```bash\r\nagfs:/> cp local:/tmp/data.txt /s3fs/mybucket/   # upload local file to S3\r\nagfs:/> cp /s3fs/mybucket/config.json /memfs/    # copy S3 file to memory\r\n```\r\n\r\n## AGFS Scripts\r\n\r\nAGFS shell supports scripting with `.as` files. Scripts use familiar shell syntax and can be executed directly.\r\n\r\n**task_worker.as** - A simple task queue worker:\r\n\r\n```bash\r\n#!/usr/bin/env agfs\r\n\r\nQUEUE_PATH=/queuefs/tasks\r\nPOLL_INTERVAL=2\r\n\r\n# Initialize queue\r\nmkdir $QUEUE_PATH\r\n\r\nwhile true; do\r\n    size=$(cat $QUEUE_PATH/size)\r\n\r\n    if [ \"$size\" = \"0\" ]; then\r\n        echo \"Queue empty, waiting...\"\r\n        sleep $POLL_INTERVAL\r\n        continue\r\n    fi\r\n\r\n    # Dequeue and process task\r\n    task=$(cat $QUEUE_PATH/dequeue)\r\n    echo \"Processing: $task\"\r\n\r\n    # Your task logic here\r\ndone\r\n```\r\n\r\n**enqueue_task.as** - Enqueue a task:\r\n\r\n```bash\r\n#!/usr/bin/env agfs\r\n\r\nmkdir /queuefs/tasks\r\necho \"$1\" > /queuefs/tasks/enqueue\r\necho \"Task enqueued. Queue size: $(cat /queuefs/tasks/size)\"\r\n```\r\n\r\nRun scripts directly:\r\n\r\n```bash\r\n./task_worker.as &\r\n./enqueue_task.as \"process report.pdf\"\r\n```\r\n\r\nSee more examples in [agfs-shell/examples](./agfs-shell/examples/).\r\n\r\n## Use Case: AI Agent Task Loop\r\n\r\nA typical agent coordination pattern: multiple agents fetch tasks from the same queue and execute them.\r\n\r\n```python\r\nwhile True:\r\n    task = agfs.cat(\"/queuefs/tasks/dequeue\")\r\n    if task:\r\n        result = execute_task(task)\r\n        agfs.write(f\"/kvfs/keys/result_{task.id}\", result)\r\n```\r\n\r\nSee [task_loop.py](./agfs-mcp/demos/task_loop.py) for a complete example.\r\n\r\n## Documentation\r\n\r\n- [agfs-server](./agfs-server/README.md) - Server configuration and plugin development\r\n- [agfs-shell](./agfs-shell/README.md) - Interactive shell client\r\n- [agfs-fuse](./agfs-fuse/README.md) - FUSE filesystem mount (Linux)\r\n"

    "content": "# AGFS MCP Server\n\nModel Context Protocol (MCP) server for AGFS (Plugin-based File System), enabling AI models to interact with AGFS through standardized tools.\n\n## Overview\n\nAGFS MCP Server exposes AGFS file system operations as MCP tools, allowing AI assistants like Claude to read, write, and manage files in a AGFS server through a standardized protocol.\n\n## Features\n\n- **File Operations**: Read, write, create, delete, copy, move files\n- **Directory Operations**: List contents, create, remove, copy directories\n- **Transfer Operations**: Upload from local filesystem to AGFS, download from AGFS to local filesystem\n- **Search**: Grep with regex pattern matching\n- **Plugin Management**: Mount/unmount plugins, list mounts\n- **Health Monitoring**: Check server status\n- **Notifications**: Send messages via QueueFS\n\n## Installation\n\n### Using uv (recommended)\n\n```bash\n# Install from local directory\nuv pip install -e .\n\n# Or if installing as dependency\nuv pip install agfs-mcp\n```\n\n### Using pip\n\n```bash\npip install -e .\n```\n\n## Usage\n\n### Starting the Server\n\nThe MCP server runs as a stdio server that communicates via JSON-RPC:\n\n```bash\n# Using default AGFS server (http://localhost:8080)\nagfs-mcp\n\n# Using custom AGFS server URL\nAGFS_SERVER_URL=http://myserver:8080 agfs-mcp\n```\n\n### Configuration with Claude Desktop\n\nAdd to your Claude Desktop configuration (`~/Library/Application Support/Claude/claude_desktop_config.json` on macOS):\n\n```json\n{\n  \"mcpServers\": {\n    \"agfs\": {\n      \"command\": \"agfs-mcp\",\n      \"env\": {\n        \"AGFS_SERVER_URL\": \"http://localhost:8080\"\n      }\n    }\n  }\n}\n```\n\nOr if using uv:\n\n```json\n{\n  \"mcpServers\": {\n    \"agfs\": {\n      \"command\": \"uvx\",\n      \"args\": [\"--from\", \"/path/to/agfs-mcp\", \"agfs-mcp\"],\n      \"env\": {\n        \"AGFS_SERVER_URL\": \"http://localhost:8080\"\n      }\n    }\n  }\n}\n```\n\n### Available Tools\n\nOnce configured, the following tools are available to AI assistants:\n\n#### File Operations\n\n- `agfs_cat` - Read file content\n  ```\n  path: File path to read\n  offset: Starting offset (optional, default: 0)\n  size: Bytes to read (optional, default: -1 for all)\n  ```\n\n- `agfs_write` - Write content to file\n  ```\n  path: File path to write\n  content: Content to write\n  ```\n\n- `agfs_rm` - Remove file or directory\n  ```\n  path: Path to remove\n  recursive: Remove recursively (optional, default: false)\n  ```\n\n- `agfs_stat` - Get file/directory information\n  ```\n  path: Path to get info about\n  ```\n\n- `agfs_mv` - Move or rename file/directory\n  ```\n  old_path: Source path\n  new_path: Destination path\n  ```\n\n- `agfs_cp` - Copy file or directory within AGFS\n  ```\n  src: Source path in AGFS\n  dst: Destination path in AGFS\n  recursive: Copy directories recursively (optional, default: false)\n  stream: Use streaming for large files (optional, default: false)\n  ```\n\n- `agfs_upload` - Upload file or directory from local filesystem to AGFS\n  ```\n  local_path: Path to local file or directory\n  remote_path: Destination path in AGFS\n  recursive: Upload directories recursively (optional, default: false)\n  stream: Use streaming for large files (optional, default: false)\n  ```\n\n- `agfs_download` - Download file or directory from AGFS to local filesystem\n  ```\n  remote_path: Path in AGFS\n  local_path: Destination path on local filesystem\n  recursive: Download directories recursively (optional, default: false)\n  stream: Use streaming for large files (optional, default: false)\n  ```\n\n#### Directory Operations\n\n- `agfs_ls` - List directory contents\n  ```\n  path: Directory path (optional, default: /)\n  ```\n\n- `agfs_mkdir` - Create directory\n  ```\n  path: Directory path to create\n  mode: Permissions mode (optional, default: 755)\n  ```\n\n#### Search Operations\n\n- `agfs_grep` - Search for pattern in files\n  ```\n  path: Path to search in\n  pattern: Regular expression pattern\n  recursive: Search recursively (optional, default: false)\n  case_insensitive: Case-insensitive search (optional, default: false)\n  ```\n\n#### Plugin Management\n\n- `agfs_mounts` - List all mounted plugins\n\n- `agfs_mount` - Mount a plugin\n  ```\n  fstype: Filesystem type (e.g., 'sqlfs', 'memfs', 's3fs')\n  path: Mount path\n  config: Plugin configuration (optional)\n  ```\n\n- `agfs_unmount` - Unmount a plugin\n  ```\n  path: Mount path to unmount\n  ```\n\n#### Health Check\n\n- `agfs_health` - Check AGFS server health status\n\n#### Notification (QueueFS)\n\n- `agfs_notify` - Send notification message via QueueFS\n  ```\n  queuefs_root: Root path of QueueFS (optional, default: /queuefs)\n  to: Target queue name (receiver)\n  from: Source queue name (sender)\n  data: Message data to send\n  ```\n  Automatically creates sender and receiver queues if they don't exist.\n\n## Example Usage with AI\n\nOnce configured, you can ask Claude (or other MCP-compatible AI assistants) to perform operations like:\n\n- \"List all files in the /data directory on AGFS\"\n- \"Read the contents of /config/settings.json from AGFS\"\n- \"Create a new directory called /logs/2024 in AGFS\"\n- \"Copy /data/file.txt to /backup/file.txt in AGFS\"\n- \"Upload my local file /tmp/report.pdf to /documents/report.pdf in AGFS\"\n- \"Download /logs/app.log from AGFS to my local /tmp/app.log\"\n- \"Copy the entire /data directory to /backup/data recursively in AGFS\"\n- \"Search for 'error' in all files under /logs recursively\"\n- \"Show me all mounted plugins in AGFS\"\n- \"Mount a new memfs plugin at /tmp/cache\"\n- \"Send a notification from 'service-a' to 'service-b' with message 'task completed'\"\n\nThe AI will use the appropriate MCP tools to interact with your AGFS server.\n\n## Environment Variables\n\n- `AGFS_SERVER_URL`: AGFS server URL (default: `http://localhost:8080`)\n\n## Requirements\n\n- Python >= 3.10\n- AGFS Server running and accessible\n- pyagfs SDK\n- mcp >= 0.9.0\n\n## Development\n\n### Setup\n\n```bash\n# Clone and install in development mode\ngit clone <repo>\ncd agfs-mcp\nuv pip install -e .\n```\n\n### Testing\n\nStart a AGFS server first, then:\n\n```bash\n# Test the MCP server manually\necho '{\"jsonrpc\":\"2.0\",\"id\":1,\"method\":\"tools/list\"}' | agfs-mcp\n```\n\n## Architecture\n\n```\n┌─────────────────┐\n│   AI Assistant  │\n│   (e.g. Claude) │\n└────────┬────────┘\n         │ MCP Protocol (JSON-RPC over stdio)\n         │\n┌────────▼────────┐\n│ AGFS MCP Server │\n│   (agfs-mcp)    │\n└────────┬────────┘\n         │ HTTP API\n         │\n┌────────▼────────┐\n│   AGFS Server   │\n│  (Plugin-based  │\n│  File System)   │\n└─────────────────┘\n```\n\n## License\n\nSee LICENSE file for details.\n\n## Related Projects\n\n- [AGFS](https://github.com/c4pt0r/agfs) -

It exposes various services—including message queues, key-value stores, databases, and remote systems—through a unified virtual file system interface.\n\n## Core Philosophy\nThe system follows the Unix philosophy of \"everything is a file\" but extends it to modern cloud services and data stores. By representing diverse backend services as file hierarchies, AGFS provides a consistent, intuitive interface for accessing heterogeneous systems.\n\n## Key Features\n\n### Plugin Architecture\nThe system allows mounting multiple filesystems and services at different paths, enabling flexible service composition. Each plugin implements the filesystem interface but can represent any kind of backend service.\n\n### External Plugin Support\nPlugins load dynamically from:\n- Shared libraries (.so on Linux, .dylib on macOS, .dll on Windows)\n- WebAssembly modules (.wasm)\n- HTTP(S) URLs for remote plugin loading\n\nThis enables extending AGFS without server recompilation or restart.\n\n### Unified API\nA single HTTP REST interface handles operations across all mounted plugins:\n- GET /api/v1/files?path=/xxx - Read file content\n- PUT /api/v1/files?path=/xxx - Write file content\n- GET /api/v1/directories?path=/xxx - List directory\n- POST /api/v1/directories?path=/xxx - Create directory\n- DELETE /api/v1/files?path=/xxx - Remove file/directory\n- GET /api/v1/stat?path=/xxx - Get file info\n- POST /api/v1/rename - Move/rename file\n- POST /api/v1/grep - Search in files\n\n### Dynamic Management\nPlugins can be managed at runtime via API:\n- Mount/unmount plugins at any path\n- Load/unload external plugins\n- Configure multiple instances of the same plugin type\n- Query mounted plugins and their configurations\n\n### Multi-Instance Capability\nThe same plugin type can run multiple independent instances. For example:\n- Multiple database connections at /db/users, /db/products, /db/logs\n- Multiple S3 buckets at /s3/backup, /s3/public, /s3/archive\n- Multiple remote servers federated at /remote/server1, /remote/server2\n\n## Architecture\n\n```\n┌─────────────────────────────────────────────┐\n│           HTTP REST API (Port 8080)         │\n│          /api/v1/files, /directories        │\n└───────────────────┬─────────────────────────┘\n                    │\n         ┌──────────▼──────────┐\n         │    MountableFS      │  ← Central router\n         │  (Path → Plugin)    │\n         └──────────┬──────────┘\n                    │\n        ┌───────────┴───────────┐\n        │                       │\n   ┌────▼─────┐          ┌─────▼────┐\n   │ Built-in │          │ External │\n   │ Plugins  │          │ Plugins  │\n   └────┬─────┘          └─────┬────┘\n        │                      │\n   ┌────▼──────────────────────▼────┐\n   │ QueueFS, KVFS, MemFS, SQLFS,  │\n   │ ProxyFS, S3FS, LocalFS, etc.  │\n   └───────────────────────────────┘\n```\n\nThe MountableFS layer routes requests to the appropriate plugin based on the requested path, enabling seamless integration of multiple services.\n\n## Built-in Plugins\n\n- **QueueFS**: Message queue operations via files (publish/subscribe)\n- **KVFS**: Key-value data storage (simple get/set operations)\n- **MemFS**: In-memory temporary storage (fast, volatile)\n- **SQLFS**: Database-backed operations (persistent, queryable)\n- **ProxyFS**: Remote server federation (mount remote AGFS servers)\n- **S3FS**: S3-compatible object storage integration\n- **LocalFS**: Local filesystem access\n- **HTTPFS**: HTTP-based file access\n\n## Common Use Cases\n\n1. **Unified Data Access**: Access databases, object storage, and local files through a single interface\n2. **Service Composition**: Combine multiple data sources at different mount points\n3. **Remote Federation**: Mount remote AGFS servers as local directories\n4. **Plugin Development**: Extend functionality with custom plugins (WebAssembly, shared libraries)\n5. **Streaming Operations**: Stream large files or continuous data (logs, metrics)\n6. **Pattern Matching**: Use grep for searching across different backends\n\n## Working with AGFS via MCP\n\nWhen using AGFS through this MCP server, you have access to all these capabilities through simple tool calls. Each tool operation maps to the AGFS REST API, allowing you to:\n- Navigate mounted plugins as directory hierarchies\n- Read/write data across different backend services\n- Search for patterns using grep\n- Manage plugin lifecycle (mount/unmount)\n- Monitor system health\n\nThe key insight is that whether you're reading from a SQL database at /db/users/data, an S3 bucket at /s3/logs/2024.txt, or a local file at /local/config.json, you use the same consistent file operations.\"\"\"\n                    )\n                )\n            raise ValueError(f\"Unknown prompt: {name}\")\n\n

    "content": "# AGFS Go SDK\n\nGo client SDK for AGFS (Abstract Global File System) HTTP API. This SDK provides a simple and idiomatic Go interface for interacting with AGFS servers.\n\n## Installation\n\nAdd the SDK to your project using `go get`:\n\n```bash\ngo get github.com/c4pt0r/agfs/agfs-sdk/go\n```\n\n## Quickstart\n\nHere is a complete example showing how to connect to an AGFS server and perform basic file operations.\n\n```go\npackage main\n\nimport (\n\t\"fmt\"\n\t\"log\"\n\n\tagfs \"github.com/c4pt0r/agfs/agfs-sdk/go\"\n)\n\nfunc main() {\n\t// 1. Initialize the client\n\t// You can point to the base URL (e.g., http://localhost:8080)\n\tclient := agfs.NewClient(\"http://localhost:8080\")\n\n\t// 2. Check server health\n\tif err := client.Health(); err != nil {\n\t\tlog.Fatalf(\"Server is not healthy: %v\", err)\n\t}\n\tfmt.Println(\"Connected to AGFS server\")\n\n\t// 3. Write data to a file (creates the file if it doesn't exist)\n\tfilePath := \"/hello.txt\"\n\tcontent := []byte(\"Hello, AGFS!\")\n\tif _, err := client.Write(filePath, content); err != nil {\n\t\tlog.Fatalf(\"Failed to write file: %v\", err)\n\t}\n\tfmt.Printf(\"Successfully wrote to %s\\n\", filePath)\n\n\t// 4. Read the file back\n\treadData, err := client.Read(filePath, 0, -1) // -1 reads the whole file\n\tif err != nil {\n\t\tlog.Fatalf(\"Failed to read file: %v\", err)\n\t}\n\tfmt.Printf(\"Read content: %s\\n\", string(readData))\n\n\t// 5. Get file metadata\n\tinfo, err := client.Stat(filePath)\n\tif err != nil {\n\t\tlog.Fatalf(\"Failed to stat file: %v\", err)\n\t}\n\tfmt.Printf(\"File info: Size=%d, ModTime=%s\\n\", info.Size, info.ModTime)\n\n\t// 6. Clean up\n\tif err := client.Remove(filePath); err != nil {\n\t\tlog.Printf(\"Failed to remove file: %v\", err)\n\t}\n\tfmt.Println(\"File removed\")\n}\n```\n\n## Usage Guide\n\n### Client Initialization\n\nYou can create a client using `NewClient`. The SDK automatically handles the `/api/v1` path suffix if omitted.\n\n```go\n// Connect to localhost\nclient := agfs.NewClient(\"http://localhost:8080\")\n```\n\nFor advanced configuration (e.g., custom timeouts, TLS), use `NewClientWithHTTPClient`:\n\n```go\nhttpClient := &http.Client{\n    Timeout: 30 * time.Second,\n}\nclient := agfs.NewClientWithHTTPClient(\"http://localhost:8080\", httpClient)\n```\n\n### File Operations\n\n#### Read and Write\nThe `Write` method includes automatic retries with exponential backoff for network errors.\n\n```go\n// Write data\nmsg, err := client.Write(\"/logs/app.log\", []byte(\"application started\"))\n\n// Read entire file\ndata, err := client.Read(\"/logs/app.log\", 0, -1)\n\n// Read partial content (e.g., first 100 bytes)\nheader, err := client.Read(\"/logs/app.log\", 0, 100)\n```\n\n#### Manage Files\n```go\n// Create an empty file\nerr := client.Create(\"/newfile.txt\")\n\n// Rename or move a file\nerr := client.Rename(\"/newfile.txt\", \"/archive/oldfile.txt\")\n\n// Change permissions\nerr := client.Chmod(\"/script.sh\", 0755)\n\n// Delete a file\nerr := client.Remove(\"/archive/oldfile.txt\")\n```\n\n### Directory Operations\n\n```go\n// Create a directory\nerr := client.Mkdir(\"/data/images\", 0755)\n\n// List directory contents\nfiles, err := client.ReadDir(\"/data/images\")\nfor _, f := range files {\n    fmt.Printf(\"%s (Dir: %v, Size: %d)\\n\", f.Name, f.IsDir, f.Size)\n}\n\n// Remove a directory recursively\nerr := client.RemoveAll(\"/data\")\n```\n\n### Advanced Features\n\n#### Streaming\nFor large files, use `ReadStream` to process data without loading it all into memory.\n\n```go\nreader, err := client.ReadStream(\"/large-video.mp4\")\nif err != nil {\n    log.Fatal(err)\n}\ndefer reader.Close()\n\nio.Copy(localFile, reader)\n```\n\n#### Server-Side Search (Grep)\nPerform regex searches directly on the server.\n\n```go\n// Recursive search for \"error\" in /var/logs, case-insensitive\nresults, err := client.Grep(\"/var/logs\", \"error\", true, true)\nfor _, match := range results.Matches {\n    fmt.Printf(\"%s:%d: %s\\n\", match.File, match.Line, match.Content)\n}\n```\n\n#### Checksums\nCalculate file digests on the server side.\n\n```go\n// Calculate xxHash3 (or \"md5\")\nresp, err := client.Digest(\"/iso/installer.iso\", \"xxh3\")\nfmt.Printf(\"Digest: %s\\n\", resp.Digest)\n```\n\n## Testing\n\nTo run the SDK tests:\n\n```bash\ngo test -v\n```\n\n## License\n\nSee the LICENSE file in the root of the repository."

    "content": "# pyagfs - AGFS Python SDK\n\nPython SDK for interacting with AGFS (Plugin-based File System) Server API.\n\nSee more details at [c4pt0r/agfs](https://github.com/c4pt0r/agfs)\n\n## Installation\n\n```bash\npip install pyagfs\n```\n\nFor local development:\n\n```bash\npip install -e .\n```\n\n## Quick Start\n\n```python\nfrom pyagfs import AGFSClient\n\n# Initialize client\nclient = AGFSClient(\"http://localhost:8080\")\n\n# Check server health\nhealth = client.health()\nprint(f\"Server version: {health.get('version', 'unknown')}\")\n\n# List directory contents\nfiles = client.ls(\"/\")\nfor file in files:\n    print(f\"{file['name']} - {'dir' if file['isDir'] else 'file'}\")\n\n# Create a new directory\nclient.mkdir(\"/test_dir\")\n\n# Write to a file\nclient.write(\"/test_dir/hello.txt\", b\"Hello, AGFS!\")\n\n# Read file content\ncontent = client.cat(\"/test_dir/hello.txt\")\nprint(content.decode())\n\n# Get file info\ninfo = client.stat(\"/test_dir/hello.txt\")\nprint(f\"Size: {info['size']} bytes\")\n\n# Remove file and directory\nclient.rm(\"/test_dir\", recursive=True)\n```\n\n## High-Level File Operations\n\nThe SDK provides helper functions for common operations like copying files within AGFS or transferring files between the local filesystem and AGFS.\n\n```python\nfrom pyagfs import AGFSClient, cp, upload, download\n\nclient = AGFSClient(\"http://localhost:8080\")\n\n# Upload local file or directory to AGFS\nupload(client, \"./local_data\", \"/remote_data\", recursive=True)\n\n# Download file or directory from AGFS to local\ndownload(client, \"/remote_data/config.json\", \"./local_config.json\")\n\n# Copy files within AGFS\ncp(client, \"/remote_data/original.txt\", \"/remote_data/backup.txt\")\n```\n\n## Advanced Usage\n\n### Streaming Operations\n\nUseful for handling large files or long-running search results.\n\n```python\n# Stream file content\nresponse = client.cat(\"/large/file.log\", stream=True)\nfor chunk in response.iter_content(chunk_size=8192):\n    process(chunk)\n\n# Stream grep results\nfor match in client.grep(\"/logs\", \"error\", recursive=True, stream=True):\n    if match.get('type') == 'summary':\n        print(f\"Total matches: {match['count']}\")\n    else:\n        print(f\"{match['file']}:{match['line']}: {match['content']}\")\n```\n\n### Mount Management\n\nDynamically mount different filesystem backends.\n\n```python\n# List mounted plugins\nmounts = client.mounts()\n\n# Mount a memory filesystem\nclient.mount(\"memfs\", \"/test/mem\", {})\n\n# Mount a SQL filesystem\nclient.mount(\"sqlfs\", \"/test/db\", {\n    \"backend\": \"sqlite\",\n    \"db_path\": \"/tmp/test.db\"\n})\n\n# Unmount a path\nclient.unmount(\"/test/mem\")\n```\n\n### Plugin Management\n\nLoad and unload external plugins (shared libraries).\n\n```python\n# Load external plugin\nresult = client.load_plugin(\"./plugins/myplugin.so\")\n\n# List loaded plugins\nplugins = client.list_plugins()\n\n# Get detailed plugin info\nplugin_infos = client.get_plugins_info()\n\n# Unload plugin\nclient.unload_plugin(\"./plugins/myplugin.so\")\n```\n\n### Search and Integrity\n\n```python\n# Recursive case-insensitive search\nresult = client.grep(\"/local\", \"warning|error\", recursive=True, case_insensitive=True)\nprint(f\"Found {result['count']} matches\")\n\n# Calculate file digest (hash)\n# Supported algorithms: \"xxh3\" (default), \"md5\"\nresult = client.digest(\"/path/to/file.txt\", algorithm=\"xxh3\")\nprint(f\"Hash: {result['digest']}\")\n```\n\n## API Reference\n\n### AGFSClient\n\n#### Constructor\n- `AGFSClient(api_base_url, timeout=10)` - Initialize client with API base URL\n\n#### File Operations\n- `ls(path=\"/\")` - List directory contents\n- `cat(path, offset=0, size=-1, stream=False)` - Read file content (alias: `read`)\n- `write(path, data, max_retries=3)` - Write data to file with retry logic\n- `create(path)` - Create new empty file\n- `rm(path, recursive=False)` - Remove file or directory\n- `stat(path)` - Get file/directory information\n- `mv(old_path, new_path)` - Move/rename file or directory\n- `chmod(path, mode)` - Change file permissions\n- `touch(path)` - Update file timestamp\n- `digest(path, algorithm=\"xxh3\")` - Calculate file hash\n\n#### Directory Operations\n- `mkdir(path, mode=\"755\")` - Create directory\n\n#### Search Operations\n- `grep(path, pattern, recursive=False, case_insensitive=False, stream=False)` - Search for pattern in files\n\n#### Mount Operations\n- `mounts()` - List all mounted plugins\n- `mount(fstype, path, config)` - Mount a plugin dynamically\n- `unmount(path)` - Unmount a plugin\n\n#### Plugin Operations\n- `list_plugins()` - List all loaded external plugins\n- `get_plugins_info()` - Get detailed info about loaded plugins\n- `load_plugin(library_path)` - Load an external plugin\n- `unload_plugin(library_path)` - Unload an external plugin\n\n#### Health Check\n- `health()` - Check server health\n\n### Helper Functions\n\n- `cp(client, src, dst, recursive=False, stream=False)` - Copy files/directories within AGFS\n- `upload(client, local_path, remote_path, recursive=False, stream=False)` - Upload from local to AGFS\n- `download(client, remote_path, local_path, recursive=False, stream=False)` - Download from AGFS to local\n\n## Development\n\n### Running Tests\n\n```bash\npip install -e \".[dev]\"\npytest\n```\n\n### Code Formatting\n\n```bash\nblack pyagfs/\nruff check pyagfs/\n```\n\n## License\n\nSee LICENSE file for details."

All file operations go through AGFS, allowing you to work with multiple backend filesystems (local, S3, SQL, etc.) through a unified interface.\n\n**Key Features:**\n- Unix-style pipelines and redirection\n- Full scripting support with control flow\n- User-defined functions with local variables (with some limitations)\n- AGFS integration for distributed file operations\n- Tab completion and command history\n- AI-powered command (llm integration)\n- Pure Python implementation (no subprocess for builtins)\n\n**Note:** This is an educational shell implementation. Advanced features like recursive functions require a full call stack implementation (future work).\n\n## Features\n\n### Core Shell Features\n- **Pipelines**: Chain commands with `|` operator\n- **I/O Redirection**: `<`, `>`, `>>`, `2>`, `2>>`\n- **Heredoc**: Multi-line input with `<<` (supports variable expansion)\n- **Variables**: Assignment, expansion, special variables (`$?`, `$1`, `$@`, etc.)\n- **Arithmetic**: `$((expression))` for calculations\n- **Command Substitution**: `$(command)` or backticks\n- **Glob Expansion**: `*.txt`, `file?.dat`, `[abc]`\n- **Control Flow**: `if/then/elif/else/fi` and `for/in/do/done`\n- **Functions**: User-defined functions with parameters, local variables, and return values (non-recursive)\n- **Comments**: `#` and `//` style comments\n\n### Built-in Commands (42+)\n- **File Operations**: cd, pwd, ls, tree, cat, mkdir, touch, rm, mv, stat, cp, upload, download\n- **Text Processing**: echo, grep, jq, wc, head, tail, tee, sort, uniq, tr, rev, cut\n- **Path Utilities**: basename, dirname\n- **Variables**: export, env, unset, local\n- **Testing**: test, [ ]\n- **Control Flow**: break, continue, exit, return, true, false\n- **Utilities**: sleep, date, plugins, mount, help\n- **AI**: llm (LLM integration)\n- **Operators**: `&&` (AND), `||` (OR) for conditional command execution\n\n### Interactive Features\n- **Tab Completion**: Commands and file paths (AGFS-aware)\n- **Command History**: Persistent across sessions (`~/.agfs_shell_history`)\n- **Multiline Editing**: Backslash continuation, quote matching\n- **Rich Output**: Colorized formatting with Rich library\n- **Dynamic Prompt**: Shows current directory\n\n### AGFS Integration\n- **Unified Interface**: Work with multiple filesystems through AGFS\n- **File Transfer**: Upload/download between local and AGFS\n- **Streaming I/O**: Memory-efficient processing (8KB chunks)\n- **Cross-filesystem Operations**: Copy between different backends\n\n## Prerequisites\n\n**AGFS Server must be running!**\n\n```bash\n# Option 1: Run from source\ncd agfs-server\ngo run main.go\n\n# Option 2: Use Docker\ndocker run -p 8080:8080 c4pt0r/agfs-server:latest\n```\n\n## Installation\n\n```bash\ncd agfs-shell\nuv sync\n```\n\n## Quick Start\n\n### Interactive Mode\n\n```bash\nuv run agfs-shell\n\nagfs:/> echo \"Hello, World!\" > /local/tmp/hello.txt\nagfs:/> cat /local/tmp/hello.txt\nHello, World!\n\nagfs:/> ls /local/tmp | grep txt\nhello.txt\n\nagfs:/> for i in 1 2 3; do\n>   echo \"Count: $i\"\n> done\nCount: 1\nCount: 2\nCount: 3\n```\n\n### Execute Command String\n\n```bash\n# Using -c flag\nuv run agfs-shell -c \"echo 'test' > /local/tmp/test.txt\"\n\n# With pipeline\nuv run agfs-shell -c \"cat /local/tmp/data.txt | sort | uniq > /local/tmp/sorted.txt\"\n```\n\n### Execute Script File\n\nCreate a script file with `.as` extension:\n\n```bash\ncat > example.as << 'EOF'\n#!/usr/bin/env uv run agfs-shell\n\n# Count files in directory\ncount=0\nfor file in /local/tmp/*; do\n    count=$((count + 1))\n    echo \"File $count: $file\"\ndone\n\necho \"Total files: $count\"\nEOF\n\nchmod +x example.as\n./example.as\n```\n\n## Shell Syntax Reference\n\n### Comments\n\n```bash\n# This is a comment (recommended)\n// This is also a comment (C-style, also supported)\n\necho \"Hello\"  # Inline comment\necho \"World\"  // Inline comment works too\n```\n\n### Pipelines\n\n```bash\n# Basic pipeline\ncommand1 | command2 | command3\n\n# Examples\ncat /local/tmp/data.txt | grep \"error\" | wc -l\nls /local/tmp | sort | head -n 10\n```\n\n### Redirection\n\n```bash\n# Input redirection\ncommand < input.txt\n\n# Output redirection\ncommand > output.txt        # Overwrite\ncommand >> output.txt       # Append\n\n# Error redirection\ncommand 2> errors.log       # Redirect stderr\ncommand 2>> errors.log      # Append stderr\n\n# Combined\ncommand < input.txt > output.txt 2> errors.log\n```\n\n### Variables\n\n```bash\n# Assignment\nNAME=\"Alice\"\nCOUNT=10\nPATH=/local/data\n\n# Expansion\necho $NAME              # Simple expansion\necho ${NAME}            # Braced expansion (preferred)\necho \"Hello, $NAME!\"    # In double quotes\n\n# Special variables\necho $?                 # Exit code of last command\necho $0                 #

Capturing function output in command substitution contexts requires either:\n\n1. **Call Stack Implementation** (like real programming languages):\n   - Each function call gets its own execution frame\n   - Frames contain local variables, parameters, and output buffer\n   - Proper stack unwinding for recursion\n\n2. **Unified Output Capture**:\n   - Refactor `execute()` to support optional output capture mode\n   - All Process objects write to configurable output streams\n   - Capture and restore output contexts across call chain\n\nThese are planned for Phase 2 of the implementation.\n\n**Workarounds:**\n- Use direct function calls instead of command substitution when possible\n- Use iterative approaches instead of recursion\n- Store results in global variables if needed\n\n## Contributing\n\nThis is an experimental/educational project.

    "content": "**LevelDB is a fast key-value storage library written at Google that provides an ordered mapping from string keys to string values.**\n\n[![Build Status](https://travis-ci.org/google/leveldb.svg?branch=master)](https://travis-ci.org/google/leveldb)\n[![Build status](https://ci.appveyor.com/api/projects/status/g2j5j4rfkda6eyw5/branch/master?svg=true)](https://ci.appveyor.com/project/pwnall/leveldb)\n\nAuthors: Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)\n\n# Features\n\n  * Keys and values are arbitrary byte arrays.\n  * Data is stored sorted by key.\n  * Callers can provide a custom comparison function to override the sort order.\n  * The basic operations are `Put(key,value)`, `Get(key)`, `Delete(key)`.\n  * Multiple changes can be made in one atomic batch.\n  * Users can create a transient snapshot to get a consistent view of data.\n  * Forward and backward iteration is supported over the data.\n  * Data is automatically compressed using the [Snappy compression library](https://google.github.io/snappy/).\n  * External activity (file system operations etc.) is relayed through a virtual interface so users can customize the operating system interactions.\n\n# Documentation\n\n  [LevelDB library documentation](https://github.com/google/leveldb/blob/master/doc/index.md) is online and bundled with the source code.\n\n# Limitations\n\n  * This is not a SQL database.  It does not have a relational data model, it does not support SQL queries, and it has no support for indexes.\n  * Only a single process (possibly multi-threaded) can access a particular database at a time.\n  * There is no client-server support builtin to the library.  An application that needs such support will have to wrap their own server around the library.\n\n# Getting the Source\n\n```bash\ngit clone --recurse-submodules https://github.com/google/leveldb.git\n```\n\n# Building\n\nThis project supports [CMake](https://cmake.org/) out of the box.\n\n### Build for POSIX\n\nQuick start:\n\n```bash\nmkdir -p build && cd build\ncmake -DCMAKE_BUILD_TYPE=Release .. && cmake --build .\n```\n\n### Building for Windows\n\nFirst generate the Visual Studio 2017 project/solution files:\n\n```cmd\nmkdir build\ncd build\ncmake -G \"Visual Studio 15\" ..\n```\nThe default default will build for x86. For 64-bit run:\n\n```cmd\ncmake -G \"Visual Studio 15 Win64\" ..\n```\n\nTo compile the Windows solution from the command-line:\n\n```cmd\ndevenv /build Debug leveldb.sln\n```\n\nor open leveldb.sln in Visual Studio and build from within.\n\nPlease see the CMake documentation and `CMakeLists.txt` for more advanced usage.\n\n# Contributing to the leveldb Project\n\nThe leveldb project welcomes contributions. leveldb's primary goal is to be\na reliable and fast key/value store. Changes that are in line with the\nfeatures/limitations outlined above, and meet the requirements below,\nwill be considered.\n\nContribution requirements:\n\n1. **Tested platforms only**. We _generally_ will only accept changes for\n   platforms that are compiled and tested. This means POSIX (for Linux and\n   macOS) or Windows. Very small changes will sometimes be accepted, but\n   consider that more of an exception than the rule.\n\n2. **Stable API**. We strive very hard to maintain a stable API. Changes that\n   require changes for projects using leveldb _might_ be rejected without\n   sufficient benefit to the project.\n\n3. **Tests**: All changes must be accompanied by a new (or changed) test, or\n   a sufficient explanation as to why a new (or changed) test is not required.\n\n4. **Consistent Style**: This project conforms to the\n   [Google C++ Style Guide](https://google.github.io/styleguide/cppguide.html).\n   To ensure your changes are properly formatted please run:\n\n   ```\n   clang-format -i --style=file <file>\n   ```\n\n## Submitting a Pull Request\n\nBefore any pull request will be accepted the author must first sign a\nContributor License Agreement (CLA) at https://cla.developers.google.com/.\n\nIn order to keep the commit timeline linear\n[squash](https://git-scm.com/book/en/v2/Git-Tools-Rewriting-History#Squashing-Commits)\nyour changes down to a single commit and [rebase](https://git-scm.com/docs/git-rebase)\non google/leveldb/master. This keeps the commit timeline linear and more easily sync'ed\nwith the internal repository at Google.

The results are somewhat noisy, but should\nbe enough to get a ballpark performance estimate.\n\n## Setup\n\nWe use a database with a million entries.  Each entry has a 16 byte\nkey, and a 100 byte value.  Values used by the benchmark compress to\nabout half their original size.\n\n    LevelDB:    version 1.1\n    Date:       Sun May  1 12:11:26 2011\n    CPU:        4 x Intel(R) Core(TM)2 Quad CPU    Q6600  @ 2.40GHz\n    CPUCache:   4096 KB\n    Keys:       16 bytes each\n    Values:     100 bytes each (50 bytes after compression)\n    Entries:    1000000\n    Raw Size:   110.6 MB (estimated)\n    File Size:  62.9 MB (estimated)\n\n## Write performance\n\nThe \"fill\" benchmarks create a brand new database, in either\nsequential, or random order.  The \"fillsync\" benchmark flushes data\nfrom the operating system to the disk after every operation; the other\nwrite operations leave the data sitting in the operating system buffer\ncache for a while.  The \"overwrite\" benchmark does random writes that\nupdate existing keys in the database.\n\n    fillseq      :       1.765 micros/op;   62.7 MB/s\n    fillsync     :     268.409 micros/op;    0.4 MB/s (10000 ops)\n    fillrandom   :       2.460 micros/op;   45.0 MB/s\n    overwrite    :       2.380 micros/op;   46.5 MB/s\n\nEach \"op\" above corresponds to a write of a single key/value pair.\nI.e., a random write benchmark goes at approximately 400,000 writes per second.\n\nEach \"fillsync\" operation costs much less (0.3 millisecond)\nthan a disk seek (typically 10 milliseconds).  We suspect that this is\nbecause the hard disk itself is buffering the update in its memory and\nresponding before the data has been written to the platter.  This may\nor may not be safe based on whether or not the hard disk has enough\npower to save its memory in the event of a power failure.\n\n## Read performance\n\nWe list the performance of reading sequentially in both the forward\nand reverse direction, and also the performance of a random lookup.\nNote that the database created by the benchmark is quite small.\nTherefore the report characterizes the performance of leveldb when the\nworking set fits in memory.  The cost of reading a piece of data that\nis not present in the operating system buffer cache will be dominated\nby the one or two disk seeks needed to fetch the data from disk.\nWrite performance will be mostly unaffected by whether or not the\nworking set fits in memory.\n\n    readrandom  : 16.677 micros/op;  (approximately 60,000 reads per second)\n    readseq     :  0.476 micros/op;  232.3 MB/s\n    readreverse :  0.724 micros/op;  152.9 MB/s\n\nLevelDB compacts its underlying storage data in the background to\nimprove read performance.  The results listed above were done\nimmediately after a lot of random writes.  The results after\ncompactions (which are usually triggered automatically) are better.\n\n    readrandom  : 11.602 micros/op;  (approximately 85,000 reads per second)\n    readseq     :  0.423 micros/op;  261.8 MB/s\n    readreverse :  0.663 micros/op;  166.9 MB/s\n\nSome of the high cost of reads comes from repeated decompression of blocks\nread from disk.  If we supply enough cache to the leveldb so it can hold the\nuncompressed blocks in memory, the read performance improves again:\n\n    readrandom  : 9.775 micros/op;  (approximately 100,000 reads per second before compaction)\n    readrandom  : 5.215 micros/op;  (approximately 190,000 reads per second after compaction)\n\n## Repository contents\n\nSee [doc/index.md](doc/index.md) for more explanation. See\n[doc/impl.md](doc/impl.md) for a brief overview of the implementation.\n\nThe public interface is in include/leveldb/*.h.  Callers should not include or\nrely on the details of any other header files in this package.  Those\ninternal APIs may be changed without warning.\n\nGuide to header files:\n\n* **include/leveldb/db.h**: Main interface to the DB: Start here.\n\n* **include/leveldb/options.h**: Control over the behavior of an entire database,\nand also control over the behavior of individual reads and writes.\n\n* **include/leveldb/comparator.h**: Abstraction for user-specified comparison function.\nIf you want just bytewise comparison of keys, you can use the default\ncomparator, but clients can write their own comparator implementations if they\nwant custom ordering (e.g. to handle different character encodings, etc.).\n\n* **include/leveldb/iterator.h**: Interface for iterating over data. You can get\nan iterator from a DB object.\n\n* **include/leveldb/write_batch.h**: Interface for atomically applying multiple\nupdates to a database.\n\n* **include/leveldb/slice.h**: A simple module for maintaining a pointer and a\nlength into some other byte array.\n\n* **include/leveldb/status.h**: Status is returned from many of the public interfaces\nand is used to report success and various kinds of errors.\n\n* **include/leveldb/env.h**:\nAbstraction of the OS environment.  A posix implementation of this interface is\nin util/env_posix.cc.\n\n* **include/leveldb/table.h, include/leveldb/table_builder.h**: Lower-level modules that most\nclients probably won't use directly.\n"

We compare LevelDB (revision 39) against <a href=\"https://www.sqlite.org/\">SQLite3</a> (version 3.7.6.3) and <a href=\"https://dbmx.net/kyotocabinet/spex.html\">Kyoto Cabinet's</a> (version 1.2.67) TreeDB (a B+Tree based key-value store). We would like to acknowledge Scott Hess and Mikio Hirabayashi for their suggestions and contributions to the SQLite3 and Kyoto Cabinet benchmarks, respectively.</p>\n\n<p>Benchmarks were all performed on a six-core Intel(R) Xeon(R) CPU X5650 @ 2.67GHz, with 12288 KB of total L3 cache and 12 GB of DDR3 RAM at 1333 MHz. (Note that LevelDB uses at most two CPUs since the benchmarks are single threaded: one to run the benchmark, and one for background compactions.) We ran the benchmarks on two machines (with identical processors), one with an Ext3 file system and one with an Ext4 file system. The machine with the Ext3 file system has a SATA Hitachi HDS721050CLA362 hard drive. The machine with the Ext4 file system has a SATA Samsung HD502HJ hard drive. Both hard drives spin at 7200 RPM and have hard drive write-caching enabled (using `hdparm -W 1 [device]`). The numbers reported below are the median of three measurements.</p>\n\n<h4>Benchmark Source Code</h4>\n<p>We wrote benchmark tools for SQLite and Kyoto TreeDB based on LevelDB's <span class=\"code\">db_bench</span>. The code for each of the benchmarks resides here:</p>\n<ul>\n\t<li> <b>LevelDB:</b> <a href=\"https://github.com/google/leveldb/blob/master/benchmarks/db_bench.cc\">benchmarks/db_bench.cc</a>.</li>\n\t<li> <b>SQLite:</b> <a href=\"https://github.com/google/leveldb/blob/master/benchmarks/db_bench_sqlite3.cc\">benchmarks/db_bench_sqlite3.cc</a>.</li>\n\t<li> <b>Kyoto TreeDB:</b> <a href=\"https://github.com/google/leveldb/blob/master/benchmarks/db_bench_tree_db.cc\">benchmarks/db_bench_tree_db.cc</a>.</li>\n</ul>\n\n<h4>Custom Build Specifications</h4>\n<ul>\n<li>LevelDB: LevelDB was compiled with the <a href=\"https://github.com/gperftools/gperftools\">tcmalloc</a> library and the <a href=\"https://github.com/google/snappy\">Snappy</a> compression library (revision 33).  Assertions were disabled.</li>\n<li>TreeDB: TreeDB was compiled using the <a href=\"https://www.oberhumer.com/opensource/lzo/\">LZO</a> compression library (version 2.03). Furthermore, we enabled the TSMALL and TLINEAR options when opening the database in order to reduce the footprint of each record.</li>\n<li>SQLite: We tuned SQLite's performance, by setting its locking mode to exclusive.  We also enabled SQLite's <a href=\"https://www.sqlite.org/draft/wal.html\">write-ahead logging</a>.</li>\n</ul>\n\n<h2>1. Baseline Performance</h2>\n<p>This section gives the baseline performance of all the\ndatabases.  Following sections show how performance changes as various\nparameters are varied.  For the baseline:</p>\n<ul>\n\t<li> Each database is allowed 4 MB of cache memory.</li>\n        <li> Databases are opened in <em>asynchronous</em> write mode.\n             (LevelDB's sync option, TreeDB's OAUTOSYNC option, and\n             SQLite3's synchronous options are all turned off).  I.e.,\n             every write is pushed to the operating system, but the\n             benchmark does not wait for the write to reach the disk.</li>\n\t<li> Keys are 16 bytes each.</li>\n        <li> Value are 100 bytes each (with enough redundancy so that\n             a simple compressor shrinks them to 50% of their original\n             size).</li>\n\t<li> Sequential reads/writes traverse the key space in increasing order.</li>\n\t<li> Random reads/writes traverse the key space in random order.</li>\n</ul>\n\n<h3>A.

Kyoto Cabinet has the fastest random read operations.</p>\n\n<h2>2. Write Performance under Different Configurations</h2>\n<h3>A. Large Values </h3>\n<p>For this benchmark, we start with an empty database, and write 100,000 byte values (~50% compressible). To keep the benchmark running time reasonable, we stop after writing 1000 values.</p>\n<h4>Sequential Writes</h4>\n<table class=\"bn bnbase\">\n<tr><td class=\"c1\">LevelDB</td>\n    <td class=\"c2\">1,100 ops/sec</td>\n    <td class=\"c3\"><div class=\"bldb\" style=\"width:234px\">&nbsp;</div></td></tr>\n<tr><td class=\"c1\">Kyoto TreeDB</td>\n    <td class=\"c2\">1,000 ops/sec</td>\n    <td class=\"c3\"><div class=\"bkct\" style=\"width:224px\">&nbsp;</div></td></tr>\n<tr><td class=\"c1\">SQLite3</td>\n    <td class=\"c2\">1,600 ops/sec</td>\n    <td class=\"c3\"><div class=\"bsql\" style=\"width:350px\">&nbsp;</div></td></tr>\n</table>\n<h4>Random Writes</h4>\n<table class=\"bn bnbase\">\n<tr><td class=\"c1\">LevelDB</td>\n    <td class=\"c2\">480 ops/sec</td>\n    <td class=\"c3\"><div class=\"bldb\" style=\"width:105px\">&nbsp;</div></td></tr>\n<tr><td class=\"c1\">Kyoto TreeDB</td>\n    <td class=\"c2\">1,100 ops/sec</td>\n    <td class=\"c3\"><div class=\"bkct\" style=\"width:240px\">&nbsp;</div></td></tr>\n<tr><td class=\"c1\">SQLite3</td>\n    <td class=\"c2\">1,600 ops/sec</td>\n    <td class=\"c3\"><div class=\"bsql\" style=\"width:350px\">&nbsp;</div></td></tr>\n</table>\n<p>LevelDB doesn't perform as well with large values of 100,000 bytes each. This is because LevelDB writes keys and values at least twice: first time to the transaction log, and second time (during a compaction) to a sorted file.\nWith larger values, LevelDB's per-operation efficiency is swamped by the\ncost of extra copies of large values.</p>\n<h3>B. Batch Writes</h3>\n<p>A batch write is a set of writes that are applied atomically to the underlying database. A single batch of N writes may be significantly faster than N individual writes. The following benchmark writes one thousand batches where each batch contains one thousand 100-byte values. TreeDB does not support batch writes and is omitted from this benchmark.</p>\n<h4>Sequential Writes</h4>\n<table class=\"bn\">\n<tr><td class=\"c1\">LevelDB</td>\n    <td class=\"c2\">840,000 entries/sec</td>\n    <td class=\"c3\"><div class=\"bldb\" style=\"width:350px\">&nbsp;</div></td>\n    <td class=\"c4\">(1.08x baseline)</td></tr>\n<tr><td class=\"c1\">SQLite3</td>\n    <td class=\"c2\">124,000 entries/sec</td>\n    <td class=\"c3\"><div class=\"bsql\" style=\"width:52px\">&nbsp;</div></td>\n    <td class=\"c4\">(2.55x baseline)</td></tr>\n</table>\n<h4>Random Writes</h4>\n<table class=\"bn\">\n<tr><td class=\"c1\">LevelDB</td>\n    <td class=\"c2\">221,000 entries/sec</td>\n    <td class=\"c3\"><div class=\"bldb\" style=\"width:350px\">&nbsp;</div></td>\n    <td class=\"c4\">(1.35x baseline)</td></tr>\n<tr><td class=\"c1\">SQLite3</td>\n    <td class=\"c2\">22,000 entries/sec</td>\n    <td class=\"c3\"><div class=\"bsql\" style=\"width:34px\">&nbsp;</div></td>\n    <td class=\"c4\">(2.23x baseline)</td></tr>\n</table>\n\n<p>Because of the way LevelDB persistent storage is organized, batches of\nrandom writes are not much slower (only a factor of 4x) than batches\nof sequential writes.</p>\n\n<h3>C. Synchronous Writes</h3>\n<p>In the following benchmark, we enable the synchronous writing modes\nof all of the databases.  Since this change significantly slows down the\nbenchmark, we stop after 10,000 writes. For synchronous write tests, we've\ndisabled hard drive write-caching (using `hdparm -W 0 [device]`).</p>\n<ul>\n    <li>For LevelDB, we set WriteOptions.sync = true.</li>\n    <li>In TreeDB, we enabled TreeDB's OAUTOSYNC option.</li>\n    <li>For SQLite3, we set \"PRAGMA synchronous = FULL\".</li>\n</ul>\n<h4>Sequential Writes</h4>\n<table class=\"bn\">\n<tr><td class=\"c1\">LevelDB</td>\n    <td class=\"c2\">100 ops/sec</td>\n    <td class=\"c3\"><div class=\"bldb\" style=\"width:350px\">&nbsp;</div></td>\n    <td class=\"c4\">(0.003x baseline)</td></tr>\n<tr><td class=\"c1\">Kyoto TreeDB</td>\n    <td class=\"c2\">7 ops/sec</td>\n    <td class=\"c3\"><div class=\"bkct\" style=\"width:27px\">&nbsp;</div></td>\n    <td class=\"c4\">(0.0004x baseline)</td></tr>\n<tr><td class=\"c1\">SQLite3</td>\n    <td class=\"c2\">88 ops/sec</td>\n    <td class=\"c3\"><div class=\"bsql\" style=\"width:315px\">&nbsp;</div></td>\n    <td class=\"c4\">(0.002x baseline)</td></tr>\n</table>\n<h4>Random Writes</h4>\n<table class=\"bn\">\n<tr><td class=\"c1\">LevelDB</td>\n    <td class=\"c2\">100 ops/sec</td>\n    <td class=\"c3\"><div class=\"bldb\" style=\"width:350px\">&nbsp;</div></td>\n    <td class=\"c4\">(0.015x baseline)</td></tr>\n<tr><td class=\"c1\">Kyoto TreeDB</td>\n    <td class=\"c2\">8 ops/sec</td>\n    <td class=\"c3\"><div class=\"bkct\" style=\"width:29px\">&nbsp;</div></td>\n    <td class=\"c4\">(0.001x baseline)</td></tr>\n<tr><td class=\"c1\">SQLite3</td>\n    <td class=\"c2\">88 ops/sec</td>\n    <td class=\"c3\"><div class=\"bsql\" style=\"width:314px\">&nbsp;</div></td>\n    <td class=\"c4\">(0.009x baseline)</td></tr>\n</table>\n\n<p>Also see the <code>ext4</code> performance numbers below\nsince synchronous writes behave significantly differently\non <code>ext3</code> and <code>ext4</code>.</p>\n\n<h3>D. Turning Compression Off</h3>\n\n<p>In the baseline measurements, LevelDB and TreeDB were using\nlight-weight compression\n(<a href=\"http://code.google.com/p/snappy/\">Snappy</a> for LevelDB,\nand <a href=\"http://www.oberhumer.com/opensource/lzo/\">LZO</a> for\nTreeDB). SQLite3, by default does not use compression.  The\nexperiments below show what happens when compression is disabled in\nall of the databases (the SQLite3 numbers are just a copy of\nits baseline measurements):</p>\n\n<h4>Sequential Writes</h4>\n<table class=\"bn\">\n<tr><td class=\"c1\">LevelDB</td>\n    <td class=\"c2\">594,000 ops/sec</td>\n    <td class=\"c3\"><div class=\"bldb\" style=\"width:350px\">&nbsp;</div></td>\n    <td class=\"c4\">(0.76x baseline)</td></tr>\n<tr><td class=\"c1\">Kyoto TreeDB</td>\n    <td class=\"c2\">485,000 ops/sec</td>\n    <td class=\"c3\"><div class=\"bkct\" style=\"width:239px\">&nbsp;</div></td>\n    <td class=\"c4\">(1.42x baseline)</td></tr>\n<tr><td class=\"c1\">SQLite3</td>\n    <td class=\"c2\">48,600 ops/sec</td>\n    <td class=\"c3\"><div class=\"bsql\" style=\"width:29px\">&nbsp;</div></td>\n    <td class=\"c4\">(1.00x baseline)</td></tr>\n</table>\n<h4>Random Writes</h4>\n<table class=\"bn\">\n<tr><td class=\"c1\">LevelDB</td>\n    <td class=\"c2\">135,000 ops/sec</td>\n    <td class=\"c3\"><div class=\"bldb\" style=\"width:296px\">&nbsp;</div></td>\n    <td class=\"c4\">(0.82x baseline)</td></tr>\n<tr><td class=\"c1\">Kyoto TreeDB</td>\n    <td class=\"c2\">159,000 ops/sec</td>\n    <td class=\"c3\"><div class=\"bkct\" style=\"width:350px\">&nbsp;</div></td>\n    <td class=\"c4\">(1.80x baseline)</td></tr>\n<tr><td class=\"c1\">SQLite3</td>\n    <td class=\"c2\">9,860 ops/sec</td>\n    <td class=\"c3\"><div class=\"bsql\" style=\"width:22px\">&nbsp;</div></td>\n    <td class=\"c4\">(1.00x baseline)</td></tr>\n</table>\n\n<p>LevelDB's write performance is better with compression than without\nsince compression decreases the amount of data that has to be written\nto disk.  Therefore LevelDB users can leave compression enabled in\nmost scenarios without having worry about a tradeoff between space\nusage and performance.  TreeDB's performance on the other hand is\nbetter without compression than with compression.  Presumably this is\nbecause TreeDB's compression library (LZO) is more expensive than\nLevelDB's compression library (Snappy).<p>\n\n<h3>E. Using More Memory</h3>\n<p>We increased the overall cache size for each database to 128 MB. For LevelDB, we partitioned 128 MB into a 120 MB write buffer and 8 MB of cache (up from 2 MB of write buffer and 2 MB of cache). For SQLite3, we kept the page size at 1024 bytes, but increased the number of pages to 131,072 (up from 4096). For TreeDB, we also kept the page size at 1024 bytes, but increased the cache size to 128 MB (up from 4 MB).</p>\n<h4>Sequential Writes</h4>\n<table class=\"bn\">\n<tr><td class=\"c1\">LevelDB</td>\n    <td class=\"c2\">812,000 ops/sec</td>\n    <td class=\"c3\"><div class=\"bldb\" style=\"width:350px\">&nbsp;</div></td>\n    <td class=\"c4\">(1.04x baseline)</td></tr>\n<tr><td class=\"c1\">Kyoto TreeDB</td>\n    <td class=\"c2\">321,000 ops/sec</td>\n    <td class=\"c3\"><div class=\"bkct\" style=\"width:138px\">&nbsp;</div></td>\n    <td class=\"c4\">(0.94x baseline)</td></tr>\n<tr><td class=\"c1\">SQLite3</td>\n    <td class=\"c2\">48,500 ops/sec</td>\n    <td class=\"c3\"><div class=\"bsql\" style=\"width:21px\">&nbsp;</div></td>\n    <td class=\"c4\">(1.00x baseline)</td></tr>\n</table>\n<h4>Random Writes</h4>\n<table class=\"bn\">\n<tr><td class=\"c1\">LevelDB</td>\n    <td class=\"c2\">355,000 ops/sec</td>\n    <td class=\"c3\"><div class=\"bldb\" style=\"width:350px\">&nbsp;</div></td>\n    <td class=\"c4\">(2.16x baseline)</td></tr>\n<tr><td class=\"c1\">Kyoto TreeDB</td>\n    <td class=\"c2\">284,000 ops/sec</td>\n    <td class=\"c3\"><div class=\"bkct\" style=\"width:280px\">&nbsp;</div></td>\n    <td class=\"c4\">(3.21x baseline)</td></tr>\n<tr><td class=\"c1\">SQLite3</td>\n    <td class=\"c2\">9,670 ops/sec</td>\n    <td class=\"c3\"><div class=\"bsql\" style=\"width:10px\">&nbsp;</div></td>\n    <td class=\"c4\">(0.98x baseline)</td></tr>\n</table>\n\n<p>SQLite's performance does not change substantially when compared to\nthe baseline, but the random write performance for both LevelDB and\nTreeDB increases significantly.  LevelDB's performance improves\nbecause a larger write buffer reduces the need to merge sorted files\n(since it creates a smaller number of larger sorted files).

    "content": "## Files\n\nThe implementation of leveldb is similar in spirit to the representation of a\nsingle [Bigtable tablet (section 5.3)](https://research.google/pubs/pub27898/).\nHowever the organization of the files that make up the representation is\nsomewhat different and is explained below.\n\nEach database is represented by a set of files stored in a directory. There are\nseveral different types of files as documented below:\n\n### Log files\n\nA log file (*.log) stores a sequence of recent updates. Each update is appended\nto the current log file. When the log file reaches a pre-determined size\n(approximately 4MB by default), it is converted to a sorted table (see below)\nand a new log file is created for future updates.\n\nA copy of the current log file is kept in an in-memory structure (the\n`memtable`). This copy is consulted on every read so that read operations\nreflect all logged updates.\n\n## Sorted tables\n\nA sorted table (*.ldb) stores a sequence of entries sorted by key. Each entry is\neither a value for the key, or a deletion marker for the key. (Deletion markers\nare kept around to hide obsolete values present in older sorted tables).\n\nThe set of sorted tables are organized into a sequence of levels. The sorted\ntable generated from a log file is placed in a special **young** level (also\ncalled level-0). When the number of young files exceeds a certain threshold\n(currently four), all of the young files are merged together with all of the\noverlapping level-1 files to produce a sequence of new level-1 files (we create\na new level-1 file for every 2MB of data.)\n\nFiles in the young level may contain overlapping keys. However files in other\nlevels have distinct non-overlapping key ranges. Consider level number L where\nL >= 1. When the combined size of files in level-L exceeds (10^L) MB (i.e., 10MB\nfor level-1, 100MB for level-2, ...), one file in level-L, and all of the\noverlapping files in level-(L+1) are merged to form a set of new files for\nlevel-(L+1). These merges have the effect of gradually migrating new updates\nfrom the young level to the largest level using only bulk reads and writes\n(i.e., minimizing expensive seeks).\n\n### Manifest\n\nA MANIFEST file lists the set of sorted tables that make up each level, the\ncorresponding key ranges, and other important metadata. A new MANIFEST file\n(with a new number embedded in the file name) is created whenever the database\nis reopened. The MANIFEST file is formatted as a log, and changes made to the\nserving state (as files are added or removed) are appended to this log.\n\n### Current\n\nCURRENT is a simple text file that contains the name of the latest MANIFEST\nfile.\n\n### Info logs\n\nInformational messages are printed to files named LOG and LOG.old.\n\n### Others\n\nOther files used for miscellaneous purposes may also be present (LOCK, *.dbtmp).\n\n## Level 0\n\nWhen the log file grows above a certain size (4MB by default):\nCreate a brand new memtable and log file and direct future updates here.\n\nIn the background:\n\n1. Write the contents of the previous memtable to an sstable.\n2. Discard the memtable.\n3. Delete the old log file and the old memtable.\n4. Add the new sstable to the young (level-0) level.\n\n## Compactions\n\nWhen the size of level L exceeds its limit, we compact it in a background\nthread. The compaction picks a file from level L and all overlapping files from\nthe next level L+1. Note that if a level-L file overlaps only part of a\nlevel-(L+1) file, the entire file at level-(L+1) is used as an input to the\ncompaction and will be discarded after the compaction.  Aside: because level-0\nis special (files in it may overlap each other), we treat compactions from\nlevel-0 to level-1 specially: a level-0 compaction may pick more than one\nlevel-0 file in case some of these files overlap each other.\n\nA compaction merges the contents of the picked files to produce a sequence of\nlevel-(L+1) files. We switch to producing a new level-(L+1) file after the\ncurrent output file has reached the target file size (2MB). We also switch to a\nnew output file when the key range of the current output file has grown enough\nto overlap more than ten level-(L+2) files.  This last rule ensures that a later\ncompaction of a level-(L+1) file will not pick up too much data from\nlevel-(L+2).\n\nThe old files are discarded and the new files are added to the serving state.\n\nCompactions for a particular level rotate through the key space. In more detail,\nfor each level L, we remember the ending key of the last compaction at level L.\nThe next compaction for level L will pick the first file that starts after this\nkey (wrapping around to the beginning of the key space if there is no such\nfile).\n\nCompactions drop overwritten values. They also drop deletion markers if there\nare no higher numbered levels that contain a file whose range overlaps the\ncurrent key.\n\n### Timing\n\nLevel-0 compactions will read up to four 1MB files from level-0, and at worst\nall the level-1 files (10MB). I.e., we will read 14MB and write 14MB.\n\nOther than the special level-0 compactions, we will pick one 2MB file from level\nL. In the worst case, this will overlap ~ 12 files from level L+1 (10 because\nlevel-(L+1) is ten times the size of level-L, and another two at the boundaries\nsince the file ranges at level-L will usually not be aligned with the file\nranges at level-L+1). The compaction will therefore read 26MB and write 26MB.\nAssuming a disk IO rate of 100MB/s (ballpark range for modern drives), the worst\ncompaction cost will be approximately 0.5 second.\n\nIf we throttle the background writing to something small, say 10% of the full\n100MB/s speed, a compaction may take up to 5 seconds. If the user is writing at\n10MB/s, we might build up lots of level-0 files (~50 to hold the 5*10MB). This\nmay significantly increase the cost of reads due to the overhead of merging more\nfiles together on every read.\n\nSolution 1: To reduce this problem, we might want to increase the log switching\nthreshold when the number of level-0 files is large. Though the downside is that\nthe larger this threshold, the more memory we will need to hold the\ncorresponding memtable.\n\nSolution 2: We might want to decrease write rate artificially when the number of\nlevel-0 files goes up.\n\nSolution 3: We work on reducing the cost of very wide merges. Perhaps most of\nthe level-0 files will have their blocks sitting uncompressed in the cache and\nwe will only need to worry about the O(N) complexity in the merging iterator.\n\n### Number of files\n\nInstead of always making 2MB files, we could make larger files for larger levels\nto reduce the total file count, though at the expense of more bursty\ncompactions.  Alternatively, we could shard the set of files into multiple\ndirectories.\n\nAn experiment on an ext3 filesystem on Feb 04, 2011 shows the following timings\nto do 100K file opens in directories with varying number of files:\n\n\n| Files in directory | Microseconds to open a file |\n|-------------------:|----------------------------:|\n|               1000 |                           9 |\n|              10000 |                          10 |\n|             100000 |                          16 |\n\nSo maybe even the sharding is not necessary on modern filesystems?\n\n## Recovery\n\n* Read CURRENT to find name of the latest committed MANIFEST\n* Read the named MANIFEST file\n* Clean up stale files\n* We could open all sstables here, but it is probably better to be lazy...\n* Convert log chunk to a new level-0 sstable\n* Start directing new writes to a new log file with recovered sequence#\n\n## Garbage collection of files\n\n`RemoveObsoleteFiles()` is called at the end of every compaction and at the end\nof recovery. It finds the names of all files in the database. It deletes all log\nfiles that are not the current log file. It deletes all table files that are not\nreferenced from some level and are not the output of an active compaction.\n"

    "content": "leveldb\n=======\n\n_Jeff Dean, Sanjay Ghemawat_\n\nThe leveldb library provides a persistent key value store. Keys and values are\narbitrary byte arrays.  The keys are ordered within the key value store\naccording to a user-specified comparator function.\n\n## Opening A Database\n\nA leveldb database has a name which corresponds to a file system directory. All\nof the contents of database are stored in this directory. The following example\nshows how to open a database, creating it if necessary:\n\n```c++\n#include <cassert>\n#include \"leveldb/db.h\"\n\nleveldb::DB* db;\nleveldb::Options options;\noptions.create_if_missing = true;\nleveldb::Status status = leveldb::DB::Open(options, \"/tmp/testdb\", &db);\nassert(status.ok());\n...\n```\n\nIf you want to raise an error if the database already exists, add the following\nline before the `leveldb::DB::Open` call:\n\n```c++\noptions.error_if_exists = true;\n```\n\n## Status\n\nYou may have noticed the `leveldb::Status` type above. Values of this type are\nreturned by most functions in leveldb that may encounter an error. You can check\nif such a result is ok, and also print an associated error message:\n\n```c++\nleveldb::Status s = ...;\nif (!s.ok()) cerr << s.ToString() << endl;\n```\n\n## Closing A Database\n\nWhen you are done with a database, just delete the database object. Example:\n\n```c++\n... open the db as described above ...\n... do something with db ...\ndelete db;\n```\n\n## Reads And Writes\n\nThe database provides Put, Delete, and Get methods to modify/query the database.\nFor example, the following code moves the value stored under key1 to key2.\n\n```c++\nstd::string value;\nleveldb::Status s = db->Get(leveldb::ReadOptions(), key1, &value);\nif (s.ok()) s = db->Put(leveldb::WriteOptions(), key2, value);\nif (s.ok()) s = db->Delete(leveldb::WriteOptions(), key1);\n```\n\n## Atomic Updates\n\nNote that if the process dies after the Put of key2 but before the delete of\nkey1, the same value may be left stored under multiple keys. Such problems can\nbe avoided by using the `WriteBatch` class to atomically apply a set of updates:\n\n```c++\n#include \"leveldb/write_batch.h\"\n...\nstd::string value;\nleveldb::Status s = db->Get(leveldb::ReadOptions(), key1, &value);\nif (s.ok()) {\n  leveldb::WriteBatch batch;\n  batch.Delete(key1);\n  batch.Put(key2, value);\n  s = db->Write(leveldb::WriteOptions(), &batch);\n}\n```\n\nThe `WriteBatch` holds a sequence of edits to be made to the database, and these\nedits within the batch are applied in order. Note that we called Delete before\nPut so that if key1 is identical to key2, we do not end up erroneously dropping\nthe value entirely.\n\nApart from its atomicity benefits, `WriteBatch` may also be used to speed up\nbulk updates by placing lots of individual mutations into the same batch.\n\n## Synchronous Writes\n\nBy default, each write to leveldb is asynchronous: it returns after pushing the\nwrite from the process into the operating system. The transfer from operating\nsystem memory to the underlying persistent storage happens asynchronously. The\nsync flag can be turned on for a particular write to make the write operation\nnot return until the data being written has been pushed all the way to\npersistent storage. (On Posix systems, this is implemented by calling either\n`fsync(...)` or `fdatasync(...)` or `msync(..., MS_SYNC)` before the write\noperation returns.)\n\n```c++\nleveldb::WriteOptions write_options;\nwrite_options.sync = true;\ndb->Put(write_options, ...);\n```\n\nAsynchronous writes are often more than a thousand times as fast as synchronous\nwrites. The downside of asynchronous writes is that a crash of the machine may\ncause the last few updates to be lost. Note that a crash of just the writing\nprocess (i.e., not a reboot) will not cause any loss since even when sync is\nfalse, an update is pushed from the process memory into the operating system\nbefore it is considered done.\n\nAsynchronous writes can often be used safely. For example, when loading a large\namount of data into the database you can handle lost updates by restarting the\nbulk load after a crash. A hybrid scheme is also possible where every Nth write\nis synchronous, and in the event of a crash, the bulk load is restarted just\nafter the last synchronous write finished by the previous run. (The synchronous\nwrite can update a marker that describes where to restart on a crash.)\n\n`WriteBatch` provides an alternative to asynchronous writes. Multiple updates\nmay be placed in the same WriteBatch and applied together using a synchronous\nwrite (i.e., `write_options.sync` is set to true). The extra cost of the\nsynchronous write will be amortized across all of the writes in the batch.\n\n## Concurrency\n\nA database may only be opened by one process at a time. The leveldb\nimplementation acquires a lock from the operating system to prevent misuse.\nWithin a single process, the same `leveldb::DB` object may be safely shared by\nmultiple concurrent threads. I.e., different threads may write into or fetch\niterators or call Get on the same database without any external synchronization\n(the leveldb implementation will automatically do the required synchronization).\nHowever other objects (like Iterator and `WriteBatch`) may require external\nsynchronization. If two threads share such an object, they must protect access\nto it using their own locking protocol. More details are available in the public\nheader files.\n\n## Iteration\n\nThe following example demonstrates how to print all key,value pairs in a\ndatabase.\n\n```c++\nleveldb::Iterator* it = db->NewIterator(leveldb::ReadOptions());\nfor (it->SeekToFirst(); it->Valid(); it->Next()) {\n  cout << it->key().ToString() << \": \"  << it->value().ToString() << endl;\n}\nassert(it->status().ok());  // Check for any errors found during the scan\ndelete it;\n```\n\nThe following variation shows how to process just the keys in the range\n[start,limit):\n\n```c++\nfor (it->Seek(start);\n   it->Valid() && it->key().ToString() < limit;\n   it->Next()) {\n  ...\n}\n```\n\nYou can also process entries in reverse order. (Caveat: reverse iteration may be\nsomewhat slower than forward iteration.)\n\n```c++\nfor (it->SeekToLast(); it->Valid(); it->Prev()) {\n  ...\n}\n```\n\n## Snapshots\n\nSnapshots provide consistent read-only views over the entire state of the\nkey-value store.  `ReadOptions::snapshot` may be non-NULL to indicate that a\nread should operate on a particular version of the DB state. If\n`ReadOptions::snapshot` is NULL, the read will operate on an implicit snapshot\nof the current state.\n\nSnapshots are created by the `DB::GetSnapshot()` method:\n\n```c++\nleveldb::ReadOptions options;\noptions.snapshot = db->GetSnapshot();\n... apply some updates to db ...\nleveldb::Iterator* iter = db->NewIterator(options);\n... read using iter to view the state when the snapshot was created ...\ndelete iter;\ndb->ReleaseSnapshot(options.snapshot);\n```\n\nNote that when a snapshot is no longer needed, it should be released using the\n`DB::ReleaseSnapshot` interface. This allows the implementation to get rid of\nstate that was being maintained just to support reading as of that snapshot.\n\n## Slice\n\nThe return value of the `it->key()` and `it->value()` calls above are instances\nof the `leveldb::Slice` type. Slice is a simple structure that contains a length\nand a pointer to an external byte array. Returning a Slice is a cheaper\nalternative to returning a `std::string` since we do not need to copy\npotentially large keys and values. In addition, leveldb methods do not return\nnull-terminated C-style strings since leveldb keys and values are allowed to\ncontain `'\\0'` bytes.\n\nC++ strings and null-terminated C-style strings can be easily converted to a\nSlice:\n\n```c++\nleveldb::Slice s1 = \"hello\";\n\nstd::string str(\"world\");\nleveldb::Slice s2 = str;\n```\n\nA Slice can be easily converted back to a C++ string:\n\n```c++\nstd::string str = s1.ToString();\nassert(str == std::string(\"hello\"));\n```\n\nBe careful when using Slices since it is up to the caller to ensure that the\nexternal byte array into which the Slice points remains live while the Slice is\nin use. For example, the following is buggy:\n\n```c++\nleveldb::Slice slice;\nif (...) {\n  std::string str = ...;\n  slice = str;\n}\nUse(slice);\n```\n\nWhen the if statement goes out of scope, str will be destroyed and the backing\nstorage for slice will disappear.\n\n## Comparators\n\nThe preceding examples used the default ordering function for key, which orders\nbytes lexicographically. You can however supply a custom comparator when opening\na database.  For example, suppose each database key consists of two numbers and\nwe should sort by the first number, breaking ties by the second number. First,\ndefine a proper subclass of `leveldb::Comparator` that expresses these rules:\n\n```c++\nclass TwoPartComparator : public leveldb::Comparator {\n public:\n  // Three-way comparison function:\n  //   if a < b: negative result\n  //   if a > b: positive result\n  //   else: zero result\n  int Compare(const leveldb::Slice& a, const leveldb::Slice& b) const {\n    int a1, a2, b1, b2;\n    ParseKey(a, &a1, &a2);\n    ParseKey(b, &b1, &b2);\n    if (a1 < b1) return -1;\n    if (a1 > b1) return +1;\n    if (a2 < b2) return -1;\n    if (a2 > b2) return +1;\n    return 0;\n  }\n\n  // Ignore the following methods for now:\n  const char* Name() const { return \"TwoPartComparator\"; }\n  void FindShortestSeparator(std::string*, const leveldb::Slice&) const {}\n  void FindShortSuccessor(std::string*) const {}\n};\n```\n\nNow create a database using this custom comparator:\n\n```c++\nTwoPartComparator cmp;\nleveldb::DB* db;\nleveldb::Options options;\noptions.create_if_missing = true;\noptions.comparator = &cmp;\nleveldb::Status status = leveldb::DB::Open(options, \"/tmp/testdb\", &db);\n...\n```\n\n### Backwards compatibility\n\nThe result of the comparator's Name method is attached to the database when it\nis created, and is checked on every subsequent database open. If the name\nchanges, the `leveldb::DB::Open` call will fail. Therefore, change the name if\nand only if the new key format and comparison function are incompatible with\nexisting databases, and it is ok to discard the contents of all existing\ndatabases.\n\nYou can however still gradually evolve your key format over time with a little\nbit of pre-planning. For example, you could store a version number at the end of\neach key (one byte should suffice for most uses). When you wish to switch to a\nnew key format (e.g., adding an optional third part to the keys processed by\n`TwoPartComparator`), (a) keep the same comparator name (b) increment the\nversion number for new keys (c) change the comparator function so it uses the\nversion numbers found in the keys to decide how to interpret them.\n\n## Performance\n\nPerformance can be tuned by changing the default values of the types defined in\n`include/options.h`.\n\n### Block size\n\nleveldb groups adjacent keys together into the same block and such a block is\nthe unit of transfer to and from persistent storage. The default block size is\napproximately 4096 uncompressed bytes.  Applications that mostly do bulk scans\nover the contents of the database may wish to increase this size. Applications\nthat do a lot of point reads of small values may wish to switch to a smaller\nblock size if performance measurements indicate an improvement. There isn't much\nbenefit in using blocks smaller than one kilobyte, or larger than a few\nmegabytes. Also note that compression will be more effective with larger block\nsizes.\n\n### Compression\n\nEach block is individually compressed before being written to persistent\nstorage. Compression is on by default since the default compression method is\nvery fast, and is automatically disabled for uncompressible data. In rare cases,\napplications may want to disable compression entirely, but should only do so if\nbenchmarks show a performance improvement:\n\n```c++\nleveldb::Options options;\noptions.compression = leveldb::kNoCompression;\n... leveldb::DB::Open(options, name, ...) ....\n```\n\n### Cache\n\nThe contents of the database are stored in a set of files in the filesystem and\neach file stores a sequence of compressed blocks. If options.block_cache is\nnon-NULL, it is used to cache frequently used uncompressed block contents.\n\n```c++\n#include \"leveldb/cache.h\"\n\nleveldb::Options options;\noptions.block_cache = leveldb::NewLRUCache(100 * 1048576);  // 100MB cache\nleveldb::DB* db;\nleveldb::DB::Open(options, name, &db);\n... use the db ...\ndelete db\ndelete options.block_cache;\n```\n\nNote that the cache holds uncompressed data, and therefore it should be sized\naccording to application level data sizes, without any reduction from\ncompression. (Caching of compressed blocks is left to the operating system\nbuffer cache, or any custom Env implementation provided by the client.)\n\nWhen performing a bulk read, the application may wish to disable caching so that\nthe data processed by the bulk read does not end up displacing most of the\ncached contents. A per-iterator option can be used to achieve this:\n\n```c++\nleveldb::ReadOptions options;\noptions.fill_cache = false;\nleveldb::Iterator* it = db->NewIterator(options);\nfor (it->SeekToFirst(); it->Valid(); it->Next()) {\n  ...\n}\n```\n\n### Key Layout\n\nNote that the unit of disk transfer and caching is a block. Adjacent keys\n(according to the database sort order) will usually be placed in the same block.\nTherefore the application can improve its performance by placing keys that are\naccessed together near each other and placing infrequently used keys in a\nseparate region of the key space.\n\nFor example, suppose we are implementing a simple file system on top of leveldb.\nThe types of entries we might wish to store are:\n\n    filename -> permission-bits, length, list of file_block_ids\n    file_block_id -> data\n\nWe might want to prefix filename keys with one letter (say '/') and the\n`file_block_id` keys with a different letter (say '0') so that scans over just\nthe metadata do not force us to fetch and cache bulky file contents.\n\n### Filters\n\nBecause of the way leveldb data is organized on disk, a single `Get()` call may\ninvolve multiple reads from disk. The optional FilterPolicy mechanism can be\nused to reduce the number of disk reads substantially.\n\n```c++\nleveldb::Options options;\noptions.filter_policy = NewBloomFilterPolicy(10);\nleveldb::DB* db;\nleveldb::DB::Open(options, \"/tmp/testdb\", &db);\n... use the database ...\ndelete db;\ndelete options.filter_policy;\n```\n\nThe preceding code associates a Bloom filter based filtering policy with the\ndatabase.  Bloom filter based filtering relies on keeping some number of bits of\ndata in memory per key (in this case 10 bits per key since that is the argument\nwe passed to `NewBloomFilterPolicy`). This filter will reduce the number of\nunnecessary disk reads needed for Get() calls by a factor of approximately\na 100. Increasing the bits per key will lead to a larger reduction at the cost\nof more memory usage. We recommend that applications whose working set does not\nfit in memory and that do a lot of random reads set a filter policy.\n\nIf you are using a custom comparator, you should ensure that the filter policy\nyou are using is compatible with your comparator. For example, consider a\ncomparator that ignores trailing spaces when comparing keys.\n`NewBloomFilterPolicy` must not be used with such a comparator. Instead, the\napplication should provide a custom filter policy that also ignores trailing\nspaces. For example:\n\n```c++\nclass CustomFilterPolicy : public leveldb::FilterPolicy {\n private:\n  FilterPolicy* builtin_policy_;\n\n public:\n  CustomFilterPolicy() : builtin_policy_(NewBloomFilterPolicy(10)) {}\n  ~CustomFilterPolicy() { delete builtin_policy_; }\n\n  const char* Name() const { return \"IgnoreTrailingSpacesFilter\"; }\n\n  void CreateFilter(const Slice* keys, int n, std::string* dst) const {\n    // Use builtin bloom filter code after removing trailing spaces\n    std::vector<Slice> trimmed(n);\n    for (int i = 0; i < n; i++) {\n      trimmed[i] = RemoveTrailingSpaces(keys[i]);\n    }\n    return builtin_policy_->CreateFilter(trimmed.data(), n, dst);\n  }\n};\n```\n\nAdvanced applications may provide a filter policy that does not use a bloom\nfilter but uses some other mechanism for summarizing a set of keys. See\n`leveldb/filter_policy.h` for detail.\n\n## Checksums\n\nleveldb associates checksums with all data it stores in the file system. There\nare two separate controls provided over how aggressively these checksums are\nverified:\n\n`ReadOptions::verify_checksums` may be set to true to force checksum\nverification of all data that is read from the file system on behalf of a\nparticular read.  By default, no such verification is done.\n\n`Options::paranoid_checks` may be set to true before opening a database to make\nthe database implementation raise an error as soon as it detects an internal\ncorruption. Depending on which portion of the database has been corrupted, the\nerror may be raised when the database is opened, or later by another database\noperation. By default, paranoid checking is off so that the database can be used\neven if parts of its persistent storage have been corrupted.\n\nIf a database is corrupted (perhaps it cannot be opened when paranoid checking\nis turned on), the `leveldb::RepairDB` function may be used to recover as much\nof the data as possible\n\n## Approximate Sizes\n\nThe `GetApproximateSizes` method can used to get the approximate number of bytes\nof file system space used by one or more key ranges.\n\n```c++\nleveldb::Range ranges[2];\nranges[0] = leveldb::Range(\"a\", \"c\");\nranges[1] = leveldb::Range(\"x\", \"z\");\nuint64_t sizes[2];\ndb->GetApproximateSizes(ranges, 2, sizes);\n```\n\nThe preceding call will set `sizes[0]` to the approximate number of bytes of\nfile system space used by the key range `[a..c)` and `sizes[1]` to the\napproximate number of bytes used by the key range `[x..z)`.\n\n## Environment\n\nAll file operations (and other operating system calls) issued by the leveldb\nimplementation are routed through a `leveldb::Env` object. Sophisticated clients\nmay wish to provide their own Env implementation to get better control.\nFor example, an application may introduce artificial delays in the file IO\npaths to limit the impact of leveldb on other activities in the system.\n\n```c++\nclass SlowEnv : public leveldb::Env {\n  ... implementation of the Env interface ...\n};\n\nSlowEnv env;\nleveldb::Options options;\noptions.env = &env;\nStatus s = leveldb::DB::Open(options, ...);\n```\n\n## Porting\n\nleveldb may be ported to a new platform by providing platform specific\nimplementations of the types/methods/functions exported by\n`leveldb/port/port.h`.  See `leveldb/port/port_example.h` for more details.\n\nIn addition, the new platform may need a new default `leveldb::Env`\nimplementation.  See `leveldb/util/env_posix.h` for an example.\n\n## Other Information\n\nDetails about the leveldb implementation may be found in the following\ndocuments:\n\n1. [Implementation notes](impl.md)\n2. [Format of an immutable Table file](table_format.md)\n3. [Format of a log file](log_format.md)\n"

    "content": "leveldb Log format\n==================\nThe log file contents are a sequence of 32KB blocks.  The only exception is that\nthe tail of the file may contain a partial block.\n\nEach block consists of a sequence of records:\n\n    block := record* trailer?\n    record :=\n      checksum: uint32     // crc32c of type and data[] ; little-endian\n      length: uint16       // little-endian\n      type: uint8          // One of FULL, FIRST, MIDDLE, LAST\n      data: uint8[length]\n\nA record never starts within the last six bytes of a block (since it won't fit).\nAny leftover bytes here form the trailer, which must consist entirely of zero\nbytes and must be skipped by readers.\n\nAside: if exactly seven bytes are left in the current block, and a new non-zero\nlength record is added, the writer must emit a FIRST record (which contains zero\nbytes of user data) to fill up the trailing seven bytes of the block and then\nemit all of the user data in subsequent blocks.\n\nMore types may be added in the future.  Some Readers may skip record types they\ndo not understand, others may report that some data was skipped.\n\n    FULL == 1\n    FIRST == 2\n    MIDDLE == 3\n    LAST == 4\n\nThe FULL record contains the contents of an entire user record.\n\nFIRST, MIDDLE, LAST are types used for user records that have been split into\nmultiple fragments (typically because of block boundaries).  FIRST is the type\nof the first fragment of a user record, LAST is the type of the last fragment of\na user record, and MIDDLE is the type of all interior fragments of a user\nrecord.\n\nExample: consider a sequence of user records:\n\n    A: length 1000\n    B: length 97270\n    C: length 8000\n\n**A** will be stored as a FULL record in the first block.\n\n**B** will be split into three fragments: first fragment occupies the rest of\nthe first block, second fragment occupies the entirety of the second block, and\nthe third fragment occupies a prefix of the third block.  This will leave six\nbytes free in the third block, which will be left empty as the trailer.\n\n**C** will be stored as a FULL record in the fourth block.\n\n----\n\n## Some benefits over the recordio format:\n\n1. We do not need any heuristics for resyncing - just go to next block boundary\n   and scan.  If there is a corruption, skip to the next block.  As a\n   side-benefit, we do not get confused when part of the contents of one log\n   file are embedded as a record inside another log file.\n\n2. Splitting at approximate boundaries (e.g., for mapreduce) is simple: find the\n   next block boundary and skip records until we hit a FULL or FIRST record.\n\n3. We do not need extra buffering for large records.\n\n## Some downsides compared to recordio format:\n\n1. No packing of tiny records.  This could be fixed by adding a new record type,\n   so it is a shortcoming of the current implementation, not necessarily the\n   format.\n\n2. No compression.  Again, this could be fixed by adding new record types.\n"

Each such pointer is called\na BlockHandle and contains the following information:\n\n    offset:   varint64\n    size:     varint64\n\nSee [varints](https://developers.google.com/protocol-buffers/docs/encoding#varints)\nfor an explanation of varint64 format.\n\n1.  The sequence of key/value pairs in the file are stored in sorted\norder and partitioned into a sequence of data blocks.  These blocks\ncome one after another at the beginning of the file.  Each data block\nis formatted according to the code in `block_builder.cc`, and then\noptionally compressed.\n\n2. After the data blocks we store a bunch of meta blocks.  The\nsupported meta block types are described below.  More meta block types\nmay be added in the future.  Each meta block is again formatted using\n`block_builder.cc` and then optionally compressed.\n\n3. A \"metaindex\" block.  It contains one entry for every other meta\nblock where the key is the name of the meta block and the value is a\nBlockHandle pointing to that meta block.\n\n4. An \"index\" block.  This block contains one entry per data block,\nwhere the key is a string >= last key in that data block and before\nthe first key in the successive data block.  The value is the\nBlockHandle for the data block.\n\n5. At the very end of the file is a fixed length footer that contains\nthe BlockHandle of the metaindex and index blocks as well as a magic number.\n\n        metaindex_handle: char[p];     // Block handle for metaindex\n        index_handle:     char[q];     // Block handle for index\n        padding:          char[40-p-q];// zeroed bytes to make fixed length\n                                       // (40==2*BlockHandle::kMaxEncodedLength)\n        magic:            fixed64;     // == 0xdb4775248b80fb57 (little-endian)\n\n## \"filter\" Meta Block\n\nIf a `FilterPolicy` was specified when the database was opened, a\nfilter block is stored in each table.  The \"metaindex\" block contains\nan entry that maps from `filter.<N>` to the BlockHandle for the filter\nblock where `<N>` is the string returned by the filter policy's\n`Name()` method.\n\nThe filter block stores a sequence of filters, where filter i contains\nthe output of `FilterPolicy::CreateFilter()` on all keys that are stored\nin a block whose file offset falls within the range\n\n    [ i*base ... (i+1)*base-1 ]\n\nCurrently, \"base\" is 2KB.  So for example, if blocks X and Y start in\nthe range `[ 0KB .. 2KB-1 ]`, all of the keys in X and Y will be\nconverted to a filter by calling `FilterPolicy::CreateFilter()`, and the\nresulting filter will be stored as the first filter in the filter\nblock.\n\nThe filter block is formatted as follows:\n\n    [filter 0]\n    [filter 1]\n    [filter 2]\n    ...\n    [filter N-1]\n\n    [offset of filter 0]                  : 4 bytes\n    [offset of filter 1]                  : 4 bytes\n    [offset of filter 2]                  : 4 bytes\n    ...\n    [offset of filter N-1]                : 4 bytes\n\n    [offset of beginning of offset array] : 4 bytes\n    lg(base)                              : 1 byte\n\nThe offset array at the end of the filter block allows efficient\nmapping from a data block offset to the corresponding filter.\n\n## \"stats\" Meta Block\n\nThis meta block contains a bunch of stats.  The key is the name\nof the statistic.  The value contains the statistic.\n\nTODO(postrelease): record following stats.\n\n    data size\n    index size\n    key size (uncompressed)\n    value size (uncompressed)\n    number of entries\n    number of data blocks\n"

Represents a JSON Pointer. Use Pointer for UTF8 encoding and default allocator.\n/*!\n    This class implements RFC 6901 \"JavaScript Object Notation (JSON) Pointer\" \n    (https://tools.ietf.org/html/rfc6901).\n\n    A JSON pointer is for identifying a specific value in a JSON document\n    (GenericDocument). It can simplify coding of DOM tree manipulation, because it\n    can access multiple-level depth of DOM tree with single API call.\n\n    After it parses a string representation (e.g. \"/foo/0\" or URI fragment \n    representation (e.g. \"#/foo/0\") into its internal representation (tokens),\n    it can be used to resolve a specific value in multiple documents, or sub-tree \n    of documents.\n\n    Contrary to GenericValue, Pointer can be copy constructed and copy assigned.\n    Apart from assignment, a Pointer cannot be modified after construction.\n\n    Although Pointer is very convenient, please aware that constructing Pointer\n    involves parsing and dynamic memory allocation. A special constructor with user-\n    supplied tokens eliminates these.\n\n    GenericPointer depends on GenericDocument and GenericValue.\n    \n    \\tparam ValueType The value type of the DOM tree. E.g. GenericValue<UTF8<> >\n    \\tparam Allocator The allocator type for allocating memory for internal representation.\n    \n    \\note GenericPointer uses same encoding of ValueType.\n    However, Allocator of GenericPointer is independent of Allocator of Value.\n*/\ntemplate <typename ValueType, typename Allocator = CrtAllocator>\nclass GenericPointer {\npublic:\n    typedef typename ValueType::EncodingType EncodingType;  //!< Encoding type from Value\n    typedef typename ValueType::Ch Ch;                      //!< Character type from Value\n\n    //!
