What is the DHH Ruby/Rails Style skill?

It's a specialized Claude Code Skill that instructs Claude to generate Ruby on Rails code following the distinct architectural and stylistic conventions of David Heinemeier Hansson (DHH), the creator of Rails, and his company 37signals.

When should I use this skill?

Use this skill when generating or refactoring any Ruby/Rails code, from controllers and models to entire applications. It's ideal for projects that follow the 37signals/Basecamp architecture or for developers who want to learn and apply these conventions.

How does this skill improve my workflow?

It ensures consistent, high-quality code generation without manual style correction. By automatically applying DHH's conventions, it lets you focus on business logic while maintaining a clean, conventional, and readable codebase.

What key architectural patterns does it enforce?

The skill enforces core DHH patterns like 'Fat Model, Thin Controller,' strict 7-action RESTful controllers, model-centric Hotwire/Turbo broadcasting, and the use of `CurrentAttributes` for managing request context.
