This is a working template pulled from a real production app (Zenith, an AI customer discovery platform), and it shows you exactly what a project guidelines skill should contain. You get architecture diagrams, file structure, actual code patterns for FastAPI responses and Claude API integration, testing setups for both pytest and Playwright, and deployment checklists. The patterns are specific enough to copy: structured output handling, custom React hooks, and the ApiResponse generic wrapper. Use this as a starting point when you need to document your own project's conventions so Claude can work within your existing codebase without constantly asking how things are organized.
