Use Context7 MCP for library APIs

Instructions

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