# Documentation Lookup > 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. Use when this capability is needed. - Skill: `tomevault-io/documentation-lookup-12` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/documentation-lookup-12` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/documentation-lookup-12/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: AI & ML - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/documentation-lookup-12 --- # Documentation Lookup (Context7) When the user asks about libraries, frameworks, or APIs, fetch current documentation via the Context7 MCP instead of relying on training data. ## When to Use - Setup or configuration questions (e.g. "How do I configure Next.js middleware?") - Code that depends on a library ("Write a Prisma query for...") - API or reference information ("What are the Supabase auth methods?") - Mentions of specific frameworks or libraries ## How It Works ### Step 1: Resolve the Library ID Call `resolve-library-id` with the library name and user's question. ### Step 2: Select the Best Match Choose by name match, benchmark score, source reputation, and version specificity. ### Step 3: Fetch the Documentation Call `query-docs` with the selected library ID and the user's specific question. ### Step 4: Use the Documentation Answer using the fetched, current information. Include relevant code examples. Cite the library or version when it matters. ## Examples ### Next.js middleware 1. Resolve: `libraryName: "Next.js"`, `query: "How do I set up middleware?"` 2. Select: `/vercel/next.js` 3. Query: fetch middleware docs 4. Answer with current patterns and code ### Prisma query 1. Resolve: `libraryName: "Prisma"`, `query: "How do I query with relations?"` 2. Select: `/prisma/prisma` 3. Query: fetch relation query docs 4. Return Prisma Client patterns with code ## Best Practices - Be specific: use the user's full question as the query - Version awareness: use version-specific library IDs when available - Prefer official sources over community forks - Limit to 3 MCP calls per question - Never send API keys or secrets in queries to Context7 --- > Source: [idiaz01/enterprise-superpowers](https://github.com/idiaz01/enterprise-superpowers) — distributed by [TomeVault](https://tomevault.io).
