Documentation Lookup

Instead of letting Claude guess at API syntax from stale training data, this skill hits Context7's MCP server for live docs whenever you mention a framework or ask how to configure something. It resolves library IDs first (Next.js becomes /vercel/next.js), then fetches current snippets and reference material for your specific question. Works across React, Prisma, Supabase, Tailwind, and most mainstream tools. The three-call limit per question keeps it from spiraling, and it automatically picks sources by benchmark score and reputation. If you're tired of Claude confidently suggesting deprecated patterns or hallucinating method names, this keeps answers grounded in what actually ships today.

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.)
