This one teaches Claude to write Ruby on Rails code the way DHH and 37signals do it, based on analysis of 265 pull requests from their Fizzy codebase. You get their opinionated approach: fat models with concerns, thin CRUD controllers, state as records instead of boolean flags, database-backed everything instead of Redis, and skipping popular gems like Devise and Sidekiq in favor of vanilla Rails. It includes their specific syntax preferences, REST resource mapping patterns, and the whole "ship prototype code to production first, refine later" philosophy. Worth using if you want to align with their distinctive style or just curious how one of the most influential Rails shops structures their code.
