Does this skill support the use of Service Objects?

No, the DHH style generally avoids service objects in favor of putting business logic directly into models or utilizing Rails concerns to keep the architecture flat and simple.

What are the preferred syntax patterns in this skill?

The skill uses modern Ruby hash syntax, symbol arrays with spaces inside brackets (%i[ action ]), and indents private methods one level under the private keyword.

What is the DHH style for Ruby on Rails?

The DHH style is a philosophy that prioritizes developer happiness and clarity. It emphasizes REST purity (7 actions per controller), fat models, thin controllers, and the use of Hotwire for frontend interactivity.

How does this skill handle controller design?

It restricts controllers to the seven standard REST actions. If you need new behavior, the skill will suggest creating a new controller for a nested or related resource rather than adding a custom action.

API Development

Generates Ruby and Rails code following David Heinemeier Hansson's signature "clarity over cleverness" philosophy and 37signals patterns.

This skill transforms Claude into an expert in the DHH/37signals school of thought for Ruby on Rails development. It enforces strict adherence to REST purity with seven-action controllers, promotes "fat models" for business logic, and utilizes modern Hotwire patterns for frontend reactivity. Whether you're building a new Rails app or refactoring existing code, this skill ensures your implementation follows the specific conventions used at Basecamp and HEY, prioritizing developer happiness and maintainability through convention over configuration and the omission of unnecessary abstractions like service objects.
