Context7 Documentation Search

This skill provides direct access to the Context7 library index, allowing you to quickly look up verified documentation and usage snippets for a wide variety of frameworks, libraries, and tools.

Requires CONTEXT7_API_KEY to be set in your environment.

Available Tools

context7_search(query, limit?)

Use this tool to find the exact ID of a library in the Context7 database.

• When to use: When you need documentation for a library but you don't know its exact Context7 libraryId.
• Example: context7_search({ query: "react hooks" })
• Returns: A list of matching libraries, their IDs (e.g., reactjs/react.dev), descriptions, and trust scores.

context7_docs(libraryId, topic?, tokens?)

Use this tool to actually read the documentation snippets for a specific library.

• When to use: Once you know the libraryId from a previous search, use this to extract the relevant text.
• Parameters:
  • libraryId: The exact ID of the library (e.g., tiangolo/fastapi).
  • topic (optional): Focus the returned snippets on a specific topic like authentication, routing, or hooks.
  • tokens (optional): Max tokens to return (default 5000).
• Example: context7_docs({ libraryId: "reactjs/react.dev", topic: "useEffect" })

Workflow

1. Always run context7_search first if you are unsure of the exact library ID.
2. Review the search results and pick the most relevant library ID.
3. Run context7_docs using the chosen ID, optionally specifying a topic to narrow down the context.
