What problem does it solve?
Context7 docs eliminates the risk of hallucinated or incorrect library API signatures by ensuring agents use verified, up-to-date documentation when building or reviewing code.
Core Features & Use Cases
- Live documentation lookup: Uses Context7 MCP to retrieve relevant, version-specific snippets and examples for unfamiliar APIs and frameworks.
- Library ID resolution: Resolves human library names into Context7 library identifiers before querying.
- Anti-hallucination workflow: Enforces verification-first rules so agents do not guess signatures or assume version compatibility.
- Session caching for continuity: Saves retrieved results into $SESSION_DIR/docs so future steps can reuse the same authoritative sources.
Quick Start
Use the context7-docs skill when you need to verify how a specific API should be called for a particular library or framework, for example, ask an agent to resolve the library ID for React and query Context7 for the correct useEffect cleanup pattern and code examples.
