c7 CLI

Fetch library documentation using the c7 CLI tool (~/.local/bin/c7).

Commands

Search Libraries

c7 search <libraryName> <query...>

Returns matching library IDs.

Fetch Documentation Context

c7 context <libraryId> <query...> -t txt

Fetches documentation for the specified library ID. Default output format: -t txt.

Workflow

1. Search — Run c7 search with the library name to get library IDs
2. Context — Run c7 context with the chosen library ID and query to fetch documentation

Best Practices

• Be specific with queries — Use detailed, natural language queries for better results (e.g., c7 context /vercel/next.js How to implement authentication with middleware instead of just auth)
• Use specific versions — Pin to an exact version for consistent results (e.g., c7 context /vercel/next.js/v15.1.8 app router)
• Handle 202 responses — A 202 status means the library is not yet finalized; wait and retry later
• Handle 301 redirects — A 301 means the library ID has moved; use the new library ID from the response
