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
