Use up-to-date library and framework docs via Context7 MCP instead of training data. Activates for setup questions, API references, code examples, or when the user names a framework (e.g. React, Next.js, Prisma).

“Common” is measured: kept by at least 6 in 10 of the 12 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

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.)

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).

How it works

Step 1: Resolve the Library ID

Call the resolve-library-id MCP tool with:

  • libraryName: The library or product name taken from the user's question (e.g. Next.js, Prisma, Supabase).
  • query: The user's full question. This improves relevance ranking of results.

You must obtain a Context7-compatible library ID (format /org/project or /org/project/version) before querying docs. Do not call query-docs without a valid library ID from this step.

Step 2: Select the Best Match

From the resolution results, choose one result using:

  • Name match: Prefer exact or closest match to what the user asked for.
  • Benchmark score: Higher scores indicate better documentation quality (100 is highest).
  • Source reputation: Prefer High or Medium reputation when available.
  • Version: If the user specified a version (e.g. "React 19", "Next.js 15"), prefer a version-specific library ID if listed (e.g. /org/project/v1.2.0).

Step 3: Fetch the Documentation

Call the query-docs MCP tool with:

  • libraryId: The selected Context7 library ID from Step 2 (e.g. /vercel/next.js).
  • query: The user's specific question or task. Be specific to get relevant snippets.

Limit: do not call query-docs (or resolve-library-id) more than 3 times per question. If the answer is unclear after 3 calls, state the uncertainty and use the best information you have rather than guessing.

Step 4: Use the Documentation

  • Answer the user's question using the fetched, current information.
  • Include relevant code examples from the docs when helpful.
  • Cite the library or version when it matters (e.g. "In Next.js 15...").

Examples

Example: Next.js middleware

  1. Call resolve-library-id with libraryName: "Next.js", query: "How do I set up Next.js middleware?".
  2. From results, pick the best match (e.g. /vercel/next.js) by name and benchmark score.
  3. Call query-docs with libraryId: "/vercel/next.js", query: "How do I set up Next.js middleware?".
  4. Use the returned snippets and text to answer; include a minimal middleware.ts example from the docs if relevant.

Example: Prisma query

  1. Call resolve-library-id with libraryName: "Prisma", query: "How do I query with relations?".
  2. Select the official Prisma library ID (e.g. /prisma/prisma).
  3. Call query-docs with that libraryId and the query.
  4. Return the Prisma Client pattern (e.g. include or select) with a short code snippet from the docs.

Example: Supabase auth methods

  1. Call resolve-library-id with libraryName: "Supabase", query: "What are the auth methods?".
  2. Pick the Supabase docs library ID.
  3. Call query-docs; summarize the auth methods and show minimal examples from the fetched docs.

Best Practices

  • Be specific: Use the user's full question as the query where possible for better relevance.
  • Version awareness: When users mention versions, use version-specific library IDs from the resolve step when available.
  • Prefer official sources: When multiple matches exist, prefer official or primary packages over community forks.
  • No sensitive data: Redact API keys, passwords, tokens, and other secrets from any query sent to Context7. Treat the user's question as potentially containing secrets before passing it to resolve-library-id or query-docs.
