Use Context7 MCP for library APIs
Instructions
- When asked about a library/package API, first resolve it: call
resolve-library-idwith the package name. - If a valid ID is returned, fetch docs with
get-library-docs(modecodefor API/reference;infofor conceptual) and a topic if relevant (e.g., hooks, routing). - Cite snippets from retrieved docs; avoid guessing. Prefer latest page unless user specifies version.
- If multiple matches, pick the closest and mention ambiguity briefly before proceeding.
- If no match, ask for clarification or alternate names instead of inventing APIs.
- Do not rely on memory for API shapes when Context7 docs are available; re-fetch as needed for accuracy.
