Installation
Summary
Fetch current library documentation via Context7 API for any external package.
- Search for libraries by name, then retrieve documentation context using the library ID and a specific query
- Supports two output formats (txt and markdown) with configurable token limits for response size
- Use proactively when working with external libraries, installing dependencies, debugging library-specific issues, or verifying APIs beyond your training data cutoff
- API key stored in
.envfile within the skill installation directory; requires Python 3 to run the CLI scripts
SKILL.md
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
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
