Does this skill support modern JavaScript frameworks like React?

No, it strictly adheres to the DHH preference for Hotwire (Turbo/Stimulus) and standard Rails partials to keep the frontend simple and integrated with the backend.

What is the core philosophy of the DHH Rails Style skill?

It follows the Omakase philosophy: utilizing vanilla Rails features and database-backed solutions (like Solid Queue) instead of reaching for external dependencies or complex abstractions like service objects.

Why does it suggest creating new controllers for simple actions?

To maintain REST purity, the skill suggests mapping actions like 'archive' to a specific 'ArchivalsController' (POST/DELETE) rather than adding custom non-CRUD methods to a primary controller.

How does this skill handle state management in models?

It encourages using records as state instead of boolean columns (e.g., using a 'Closures' table instead of a 'closed' boolean), allowing for better auditing and historical data tracking.

API Development

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.
