Applies the opinionated 37signals and DHH Omakase patterns to Ruby on Rails development.
This skill transforms Claude into a domain expert on the distinctive Ruby and Rails patterns pioneered by DHH and the 37signals team. It enforces 'Vanilla Rails' principles, prioritizing RESTful resource mapping over custom controller actions, database-backed state management over external services like Redis, and the classic fat model, thin controller philosophy. By leveraging patterns extracted from production codebases like Fizzy and Campfire, it guides developers in creating lean, maintainable applications using Hotwire and Stimulus while intentionally avoiding heavy dependencies like Devise, Sidekiq, or complex service objects.
