API Documentation Generation

I'll generate comprehensive OpenAPI/Swagger documentation from your API code.

Features:

• Auto-generate from Express, FastAPI, Next.js API routes
• OpenAPI 3.0 specification format
• Interactive Swagger UI setup
• Automatic schema extraction
• Integration with /api-test-generate

Token Optimization

Expected range: 1,500–2,500 tokens (initial), 400–600 tokens (cache hit)

Caching: Caches OpenAPI spec analysis in .claude/cache/api-docs/ for 7 days. Invalidated when API routes change.

Early exit: Returns immediately if spec already exists and is current.

Patterns used: Grep-before-Read, early exit, template-based generation, git diff scope default
