Context7

Context7 Documentation Skill

Fetch real-time, version-specific library documentation before implementing code.

When to Use

This skill activates automatically when Claude detects:

• External library/framework usage (React, Next.js, Vue, FastAPI, etc.)
• API integration or documentation needs
• Framework setup or configuration
• Package-specific code examples

Workflow

Step 1: Resolve Library ID

Tool: mcp__context7__resolve-library-id
Input: { "libraryName": "<library-name>" }
Output: Context7-compatible library ID

Step 2: Fetch Documentation

Tool: mcp__context7__get-library-docs
Input: { 
  "context7CompatibleLibraryID": "<resolved-id>",
  "topic": "<optional-topic-filter>",
  "tokens": 5000
}

Step 3: Apply Documentation

• Base all code suggestions on retrieved documentation
• Use current API patterns, not training data

Direct Library ID Syntax

Users can skip resolution with explicit IDs:

"use library /vercel/next.js for implementing app router"
"use library /supabase/supabase for authentication"
