Docs Lookup

The Docs Lookup skill provides context injection for querying library and framework documentation using Context7.

Overview

Property	Value
Skill ID	ct-docs-lookup
Tier	3 (Support)
Protocol	research
Tags	documentation, libraries

When to Use

Activate this skill when the user:

• Asks setup or configuration questions (“How do I configure Next.js middleware?”)
• Requests code involving libraries (“Write a Prisma query for…”)
• Needs API references (“What are the Supabase auth methods?”)
• Mentions specific frameworks (React, Vue, Svelte, Express, Tailwind, etc.)

Workflow

Step 1: Resolve Library ID

Call resolve-library-id with:

• libraryName: The library name from user’s question
• query: The user’s full question

Step 2: Select Best Match

From results, choose based on:

• Exact or closest name match
• Higher benchmark scores
• Version-specific IDs if user mentioned version

Step 3: Fetch Documentation

Call query-docs with:

• libraryId: Selected Context7 library ID (e.g., /vercel/next.js)
• query: User’s specific question

Step 4: Use Documentation

• Answer using current, accurate information
• Include relevant code examples
• Cite library version when relevant

Guidelines

• Be specific: Pass full question as query
• Version awareness: Use version-specific IDs when mentioned (“Next.js 15”, “React 19”)
• Prefer official sources: Choose official packages over community forks

Example

User: "How do I set up authentication with Next.js App Router?"

1. resolve-library-id("next.js", "set up authentication with Next.js App Router")
   → /vercel/next.js

2. query-docs("/vercel/next.js", "authentication App Router setup")
   → Current documentation with code examples

3. Provide answer with accurate, version-specific information

Integration with Documentor
