Documentation Lookup

When you ask Claude about React hooks, Next.js middleware, or Prisma queries, this skill hits the Context7 MCP server for live docs instead of relying on stale training data. It resolves library names to IDs, fetches current snippets and API references, then answers with up-to-date code examples. The three-call limit keeps it from spinning, and it knows to prefer official sources and version-specific docs when you mention them. Honest take: this is what you want when frameworks ship breaking changes every quarter and you need Claude to know about the middleware.ts pattern that landed last month, not the deprecated config from two years ago.

Documentation Lookup (Context7)

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.

Core Concepts

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.

When to use

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.)
