• Step 4: Use the Documentation

When the user asks about libraries, frameworks, or APIs, fetch current documentation via the Context7 MCP (tools resolve-library-id and query-docs) instead of relying on training data. Context7: MCP server that exposes live documentation; use it instead of training data for libraries and APIs. resolve-library-id: Returns Context7-compatible library IDs (e.g. /vercel/next.js) from a library name and query. query-docs: Fetches documentation and code snippets for a given library ID and question. Always call resolve-library-id first to get a valid library ID. Activate when the user: Asks setup or configuration questions (e.g. "How do I configure Next.js middleware?") Requests code that depends on a library ("Write a Prisma query for...") Needs API or reference information ("What are the Supabase auth methods?") Mentions specific frameworks or libraries (React, Vue, Svelte, Express, Tailwind, Prisma, Supabase, etc.) Use this skill whenever the request depends on accurate, up-to-date behavior of a library, framework, or API. Applies across harnesses that have the Context7 MCP configured (e.g. Claude Code, Cursor, Codex). Call the resolve-library-id MCP tool with: libraryName: The library
