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 Do not rely on outdated knowledge. Always prefer this over guessing library APIs or using outdated knowledge.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.
Authentication
This skill requires a Context7 API key in CONTEXT7_API_KEY.
Recommended setup options:
- Export it in your shell profile (global):
export CONTEXT7_API_KEY="your-context7-key"
- Use a local
.envfile (per-repo):
cp skills/context7/.env.example .env
set -a; source .env; set +a
Workflow
1. Search for the library
python3 ~/.codex/skills/context7/scripts/context7.py search "<library-name>"
Example:
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
python3 ~/.codex/skills/context7/scripts/context7.py context "<library-id>" "<query>"
Example:
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
