Context7 (Library Documentation)

Use Context7 to query up-to-date documentation for any library before implementing code.

Tools

Workflow

Always query docs before implementing:

Copy1. resolve_library_id({ libraryName: "effect typescript" })
   → Returns: /effect-ts/effect

2. get_library_docs({ 
     context7CompatibleLibraryID: "/effect-ts/effect", 
     topic: "schema validation" 
   })
   → Returns: Up-to-date documentation

Common Library IDs

Best Practices

1. Always resolve first - Don't guess library IDs
2. Be specific with topics - "schema validation" not just "validation"
3. Query before coding - Get current patterns, not outdated knowledge
4. Check multiple topics - Query auth, then session, then middleware separately

Example Queries

Copy# React patterns
get_library_docs({ libraryId: "/facebook/react", topic: "useEffect cleanup" })

# Authentication
get_library_docs({ libraryId: "/better-auth/better-auth", topic: "next.js integration" })

# Type-safe APIs
get_library_docs({ libraryId: "/effect-ts/effect", topic: "tagged errors" })
