Context7 Lookup Skill

Fetches up-to-date, version-specific library documentation via Context7 MCP server (68,000+ libraries). Fully language-agnostic - works with Node.js, Python, Java, Rust, Go, Ruby, PHP, C#, Swift, and more.

Purpose

Prevent hallucinated APIs and outdated code examples by fetching current documentation from official sources.

Auto-detects Versions From

Node.js • Python • Java • Rust • Ruby • Go • PHP • C#/.NET • Swift

(package.json, requirements.txt, Cargo.toml, pom.xml, Gemfile, go.mod, composer.json, *.csproj, Podfile)

Integration

• Planner: Research phase (Step 4) for library investigation
• Developer: Pre-implementation (Step 2.5) to verify APIs
• Reviewer: Optional verification during code review

How It Works

1. Detect Version: grep_search dependency files
2. Resolve Library: mcp_context7_resolve-library-id
3. Fetch Docs: mcp_context7_query-docs
4. Apply: Use verified API patterns

Examples

Python: Django ORM • Flask routes • SQLAlchemy Rust: Tokio async • Serde serialization Java: Spring Boot • Hibernate JS/TS: Next.js • React • Express Go: Gin router • GORM

Benefits

✅ Current, version-specific docs ✅ No hallucinated APIs ✅ Official examples ✅ Prevents "method not found" errors
