Claude-skill-registry context7

Fetch up-to-date library documentation using Context7 API. Use this skill when the user asks for docs, examples, or help with a specific library/framework (e.g., "look up React docs", "context7 nextjs routing", "fetch docs for fastapi").

Context7 Documentation Fetcher

This skill fetches up-to-date documentation and code examples from libraries using the Context7 API.

Standard Workflow

Context7 requires a two-step process:

Step 1: Search for the Library ID

First, search for the library to get its ID:

GET https://context7.com/api/v2/libs/search?libraryName=<library>&query=<context>

Parameters:

  • libraryName
    : The library name (e.g., "react", "nextjs", "fastapi")
  • query
    : Search context to help find the right library

The response contains a

results
array with library objects. Use the
id
field from the first result.

Step 2: Get Documentation Context

Use the library ID to fetch relevant documentation:

GET https://context7.com/api/v2/context?libraryId=<id>&query=<question>

Parameters:

  • libraryId
    : The ID from step 1 (e.g., "/vercel/next.js")
  • query
    : Natural language question about the documentation

This returns ranked code snippets and documentation matching your query.

Example Usage

When the user asks about a library:

  1. Search for the library: Fetch

    https://context7.com/api/v2/libs/search?libraryName=nextjs&query=routing
    Extract the library ID from the response (e.g., "/vercel/next.js")

  2. Fetch documentation: Fetch

    https://context7.com/api/v2/context?libraryId=/vercel/next.js&query=How to setup dynamic routes

  3. Present the results to the user with the relevant code examples and documentation.

Tips for Best Results

  • Use specific, detailed queries rather than vague terms
  • Include relevant context in the query (e.g., "useState hook with TypeScript" instead of just "state")
  • The API works without an API key but has restricted rate limits
