Free AI Coding Skills for Rails — Opinionated Patterns That Work

Teaches your AI to write Rails the way 37signals does — the team behind Basecamp and HEY.

• Rich models, thin controllers
• CRUD controllers with concerns
• Minitest with fixtures
• No service objects

What this means for you: Your AI writes less custom code — which means fewer bugs, lower maintenance costs, and less time fixing things that shouldn’t have been built from scratch.

Walks your AI through setting up a new Rails app with a proven, production-ready stack.

• Interactive interview before scaffolding
• Full post-scaffold configuration
• Phlex or ERB — your choice
• Pundit, Solid Queue, AASM
• Production-ready from the start

What this means for you: Your next app starts on solid ground. No expensive rework when you need to scale or hand it off to a new team.

Guides your AI to build UI components that are fast, testable, and follow a clear hierarchy.

• Component hierarchy and slots
• Stimulus and Turbo integration
• Custom elements and helpers
• Fragment caching patterns
• Rails scaffold generator

What this means for you: Your interface stays consistent as your app grows. Updates happen in one place instead of hunting through every page.
