context7
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 (6) AND MOST IMPORTANTLY, when you are installing dependencies, libraries, or frameworks you should ALWAYS check the docs to see what the latest versions are. Do not rely on outdated knowledge. Always prefer this over guessing library APIs or using outdated knowledge.

# Context7 Documentation Fetcher Retrieve current library documentation via Context7 API. IMPORTANT: `CONTEXT7_API_KEY` IS STORED IN THE .env FILE IN THE SKILL FOLDER THAT THE CONTEXT7 SKILL IS INSTALLED IN. SEARCH FOR IT THERE. .env FILES ARE HIDDEN FILES. Example: ~/.agents/skills/context7/.env ~/.claude/skills/context7/.env ## Workflow ### 1. Search for the library ```bash python3 ~/.codex/skills/context7/scripts/context7.py search "<library-name>" ``` Example: ```bash python3 ~/.codex/skills/context7/scripts/context7.py search "next.js" ``` Returns library metadata including the `id` field needed for step 2. ### 2. Fetch documentation context ```bash python3 ~/.codex/skills/context7/scripts/context7.py context "<library-id>" "<query>" ``` Example: ```bash python3 ~/.codex/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
