Ruby Rails

This turns Claude into a Rails developer who actually follows conventions. You get opinionated guidance on MVC architecture, ActiveRecord optimization with N+1 prevention, and modern Rails patterns like Hotwire instead of heavy JavaScript frameworks. It pushes service objects for business logic, ViewComponents for reusable UI, and proper testing with RSpec or Minitest. The security coverage is solid with reminders about strong parameters and CSRF tokens. If you're building Rails apps and want Claude to write idiomatic Ruby 3.x code that doesn't fight the framework, this keeps everything aligned with current Rails best practices instead of generic web development advice.

Ruby on Rails

This skill covers Ruby and Ruby on Rails development, including Rails conventions, ActiveRecord patterns, frontend integration, security, and testing.

Core Principles

Write concise, idiomatic Ruby code with accurate examples
Adhere to Rails conventions (Convention over Configuration)
Follow the Ruby Style Guide for formatting consistency
Leverage Ruby 3.x features like pattern matching and endless methods
Prefer Rails command-line generators (bin/rails generate ...) over hand-written boilerplate — they keep files consistent with framework conventions and wire up tests/routes automatically
Use bin/dev to run the local development server (it boots the web process plus any configured watchers) and check logs after significant changes
