What this skill does

When applied, it prepends a system prompt before your request is sent — no extra calls and no change to how you are billed beyond the added tokens.

# 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 ste
