c7

name: c7 description: Fetch up-to-date library documentation. Use when the user asks to look up docs, documentation, check API usage, or tells you to use context7.

Context7 Skill

Use the c7 CLI to fetch current library documentation from Context7.

Quick lookup

The get command resolves a library name and fetches docs in one step:

c7 get <library-name> "<query>"

Examples:

c7 get rails "active record scopes"
c7 get next.js "middleware routing"
c7 get tailwindcss "responsive grid"
c7 get kamal "deploy with secrets" --tokens 8000

Use --tokens N to control how much documentation is returned (default 5000).

Search for a library

When you need the exact library ID first:

c7 search <library-name>

Fetch docs by known ID

When the library ID is already known (e.g. from a previous search):

c7 docs <library-id> "<query>"
c7 docs /rails/rails "validations" --tokens 8000 --topic models

Flags: --tokens N, --page N (1–10), --topic TOPIC.

Guidelines

• Prefer get for one-shot lookups — it caches resolved IDs automatically.
• Use search when the user wants to browse or compare libraries.
• Use docs when a library ID is already known from prior context.
• Pipe output or read it directly — it's plain text / markdown, ready to use.
• Run c7 cache clear if results seem stale.
