Rails code review enforces adherence to Rails conventions by auditing controller skinnyness, model fatness, proper ActiveRecord usage, and RESTful routing patterns. This skill delivers actionable feedback aligned with Rails philosophy to catch anti-patterns and ensure idiomatic Rails architecture.

Common Rails anti-patterns include unnecessary service objects where model methods suffice, overuse of decorators instead of helpers, premature microservices, and GraphQL adoption when REST and Rails conventions better fit the problem. This skill flags these deviations and proposes Rails-aligned alternatives.

JavaScript-centric patterns erode Rails conventions when frontend-driven abstractions override Rails' monolithic, convention-driven approach. This skill identifies those patterns and recommends Rails-native solutions to preserve architectural coherence.

Yes. This skill audits new Rails features and refactors to ensure they adhere to Rails conventions, avoid architectural anti-patterns, and maintain Rails philosophy. It applies to any codebase review where Rails idiomatic usage matters.

Rails conventions favor fat models, skinny controllers, and RESTful routes; unnecessary abstractions like overengineered service objects or decorator layers add complexity without Rails-aligned benefit. This skill distinguishes legitimate patterns from over-abstraction.
