What is the recommended token limit for documentation snippets?

A limit of 2,000 tokens is ideal for quick function lookups, 5,000 for typical usage examples, and up to 10,000 for broad exploration or migration guides.

Do I need an API key to use this skill?

Yes, this skill requires a CONTEXT7_API_KEY environment variable to authenticate requests with the Context7 API.

How do I find the correct library ID for a fetch command?

You should always run the 'search' command first (e.g., search react 'hooks'). The search results will provide the specific ID (like /websites/react_dev) needed for the fetch step.

Why should I use Context7 instead of Claude's internal knowledge?

Claude's training data has a fixed cutoff date. Context7 fetches live, real-time documentation, which is essential for libraries that update frequently or have recently introduced breaking changes.

Can I use Context7 to search my own local code base?

No, Context7 is specifically designed for public open-source libraries and frameworks. For internal project code, you should use standard file-reading or grep tools.

Fetches real-time, up-to-date documentation and API references for open-source libraries and frameworks.

Context7 bridges the gap between Claude's training data cutoffs and the rapidly evolving landscape of software libraries by providing direct access to the latest documentation. It allows developers to search for specific library versions, find accurate API signatures, and retrieve migration guides or code examples directly from current sources. By fetching high-relevance snippets from the Context7 API, this skill ensures that the AI generates code compatible with the latest library updates, effectively preventing errors caused by deprecated functions or breaking changes in newer releases.
