  • Naming & structure guidance: Enforce clear class/module naming, predicate methods, bang methods, and Ruby conventions.
  • Best practices in code organization: Promote small, focused methods, duck typing, and minimal boilerplate across projects.
  • Use Case: A team migrating a Ruby project to adopt consistent style and improved readability for new contributors.

Quick Start

Invoke the Ruby best-practices skill when starting a new Ruby module or performing code reviews to align with Ruby conventions.

Frequently Asked Questions about programming-ruby

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
What are the Ruby naming conventions for classes, modules, and predicate methods?▼

Ruby naming conventions require snake_case for variables and methods, CamelCase for classes and modules, and question marks for predicate methods to indicate boolean return values, ensuring code remains idiomatic and maintainable.

How do I enforce consistent Ruby coding guidelines during code reviews?▼

You can enforce Ruby coding guidelines during code reviews by applying this Skill to check for 2-space indentation, conventional block styles, and small focused methods, reducing bike-shedding and aligning new contributors with community best practices.

What is duck typing and how should I structure Ruby methods around it?▼

Duck typing in Ruby means defining method interactions based on available behaviors rather than specific classes, promoting small, focused methods and minimal boilerplate while ensuring readable metaprogramming patterns.

When should I use bang methods in Ruby and what are the safety implications?▼

Bang methods in Ruby should be reserved for destructive or dangerous operations that modify the receiver in place, such as mutating state. This Skill provides guidance on naming them clearly to enforce safe, readable metaprogramming patterns.

Does this Ruby best practices guidance apply to both libraries and applications?▼

Yes, this Ruby best practices guidance targets everyday Ruby libraries and applications, providing precise scope across projects for style, naming, and structure to improve onboarding and maintainability.
