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+Prevent hallucinated APIs and outdated code examples by fetching current documentation from official sources.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