Backend Development

This one gives Claude a practical reference for building backend systems, covering REST conventions, database schemas with UUID patterns, JWT auth, and caching strategies. You'll want it when designing APIs from scratch or reviewing architecture decisions. The examples are opinionated in a good way: soft deletes, cursor pagination, structured error responses, rate limiting middleware. It's not comprehensive documentation, more like a cheat sheet of sensible defaults. Useful for getting consistent patterns across endpoints without reinventing conventions every time, and the SQL snippets alone save you from looking up index syntax.
