Ruby Idioms and Patterns

What problem does it solve?

This Skill helps you produce Ruby code that follows modern language conventions, is easier to read and maintain, and behaves correctly under real-world error and testing requirements.

Core Features & Use Cases

• Modern Ruby 3.x idioms: apply pattern matching, endless methods, and immutable value objects (Data) for clearer intent.
• Robust error handling: design domain exception hierarchies and avoid unsafe patterns like bare rescue while ensuring cleanup via ensure.
• Consistent naming, testing, and quality gates: enforce Ruby-friendly naming rules and validate behavior with RSpec/Minitest plus static analysis tools.

Use case: When refactoring a Rails-like service, you can standardize error types, adopt pattern matching for branching logic, and improve test reliability with RSpec and factories.

Quick Start

Use the Ruby Idioms and Patterns skill to guide an agent to rewrite a Ruby service method according to Ruby 3.x conventions, domain-specific exceptions, and RSpec coverage.
