Context7 Documentation Lookup Skill
Fetch current library documentation, API references, and code examples via the Context7 REST API.
When to Use
Use this skill when the user asks about library APIs, framework patterns, or version-specific behavior. Trigger on:
- Library questions: "How do I use [library]?", "[library] API docs", "[library] patterns"
- Import statements:
import,require,fromfollowed by a library name - Framework-specific topics: hooks, routing, middleware, ORM queries, schema definitions
When NOT to Use
Do NOT use this skill for:
- General programming concepts (closures, recursion, design patterns)
- Code review or refactoring tasks
- Debugging business logic
- Writing scripts from scratch without library-specific questions
Core Workflow
-
Search for the library ID:
scripts/context7.sh search "library-name" -
Pick the best result: Choose the ID with the highest score and most relevant description. Prefer official sources (e.g.,
/vercel/next.jsover community forks). -
Fetch documentation with a focused topic:
scripts/context7.sh docs "<library-id>" "<topic>" "<mode>"
Always extract a specific topic from the user's question. For "How does React Suspense work with server components?", use topic suspense server components.
Parameters
| Parameter | Required | Description |
|---|---|---|
library-id | Yes | From search results, format /vendor/library |
topic | No | Focus area extracted from user query (e.g., hooks, routing, validation) |
mode | No | code (default) for API references; info for conceptual guides |
Mode Selection
Use code mode (default) when the user asks for API references, code examples, or implementation patterns.
Use info mode when the user asks for conceptual explanations, architecture guides, or migration tutorials.
Examples
# React hooks API
scripts/context7.sh search "react"
scripts/context7.sh docs "/facebook/react" "hooks" "code"
# Next.js App Router conceptual guide
scripts/context7.sh search "nextjs"
scripts/context7.sh docs "/vercel/next.js" "app router" "info"
# Django ORM queries
scripts/context7.sh search "django"
scripts/context7.sh docs "/django/django" "queryset filter" "code"
# Laravel Eloquent relationships
scripts/context7.sh search "laravel"
scripts/context7.sh docs "/laravel/framework" "eloquent relationships" "code"
Environment Configuration
Set CONTEXT7_API_KEY for higher rate limits (optional):
