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

Naming Conventions

• Use snake_case for files, methods, and variables
• Use CamelCase for classes and modules
• Follow Rails naming conventions for models, controllers, views
