Context7 Documentation Lookup Skill

Fetch current library documentation, API references, and code examples without MCP context overhead.

When to Use This Skill

When the user asks about library APIs or framework patterns, use this skill to fetch current documentation.

When encountering import statements (import, require, from), use this skill to provide accurate API information.

When the user asks about specific library versions or "How do I use X library?", use this skill to get official patterns.

To answer questions about library documentation, follow these steps:

To find a library ID for documentation lookup:

scripts/context7.sh search "library-name"

This returns library IDs in the format /vendor/library (e.g., /facebook/react).

To fetch documentation for a specific library:

scripts/context7.sh docs "<library-id>" "[topic]" "[mode]"

Parameters:

library-id (required): From search result (e.g., /facebook/react)
topic (optional): Focus area (e.g., hooks, routing, authentication)
mode (optional): code for API references (default) or info for conceptual guides

To get React hooks documentation:

scripts/context7.sh search "react"
scripts/context7.sh docs "/facebook/react" "hooks" "code"

To get Next.js routing guide:

scripts/context7.sh search "nextjs"
scripts/context7.sh docs "/vercel/next.js" "routing" "info"

When fetching API references, examples, or code patterns, use code mode (default).

When fetching conceptual guides, tutorials, or explanations, use info mode.

To use authenticated requests (optional), set the CONTEXT7_API_KEY environment variable:

export CONTEXT7_API_KEY="your-api-key"
