description

Fetch up-to-date library documentation via Context7 API. Use PROACTIVELY when: (1) Working with ANY external library (React, Next.js, Supabase, etc.) (2) User asks about library APIs, patterns, or best practices (3) Implementing features that rely on third-party packages (4) Debugging library-specific issues (5) Need current documentation beyond training data cutoff Always prefer this over guessing library APIs or using outdated knowledge.

Context7 Documentation Fetcher

Retrieve current library documentation via Context7 API.

Workflow

1. Search for the library

python3 ~/.claude/skills/context7/scripts/context7.py search "<library-name>"

Example:

python3 ~/.claude/skills/context7/scripts/context7.py search "next.js"

Returns library metadata including the id field needed for step 2.

2. Fetch documentation context

python3 ~/.claude/skills/context7/scripts/context7.py context "<library-id>" "<query>"

Example:

python3 ~/.claude/skills/context7/scripts/context7.py context "/vercel/next.js" "app router middleware"

Options:

• --type txt|md - Output format (default: txt)
• --tokens N - Limit response tokens

Quick Reference

Task	Command
Find React docs	search "react"
Get React hooks info	context "/facebook/react" "useEffect cleanup"
Find Supabase	search "supabase"
Get Supabase auth	context "/supabase/supabase" "authentication row level security"

When to Use

• Before implementing any library-dependent feature
• When unsure about current API signatures
• For library version-specific behavior
• To verify best practices and patterns
