What context7 does

The skill searches for a library in Context7, then selects an ID using its trust score, available snippets, and version information. It requests material for a focused topic and uses the result to explain an API or prepare a code example.

Ask it to check how a library works, show a usage example, or verify version-specific details. API requests require CONTEXT7_API_KEY; without that credential, the documented curl calls cannot authenticate. For a combined example using multiple libraries, the skill resolves and retrieves documentation for each one.

What it helps with

check the current way to call a library API
find an example for a specific function
verify documentation for a particular library version
build an example that combines multiple libraries

Example prompts for the agent

Check the current React useEffect cleanup pattern through Context7 and show an example.
Find how to configure authentication middleware in the Next.js App Router using Context7.
Compare the Context7 docs for TailwindCSS and shadcn/ui, then draft a button example.
