AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

Ruby-pro acts as a specialized assistant for Ruby and Ruby on Rails development. It emphasizes clean, maintainable, and performant code by leveraging Ruby's unique features like metaprogramming, blocks, and enumerables. The skill is designed to guide developers through complex tasks ranging from gem development and Rails MVC architecture to performance profiling and rigorous testing with RSpec or Minitest.

What it does

  • Generates idiomatic Ruby code following community best practices.
  • Provides guidance on Rails patterns and MVC architecture.
  • Assists with advanced metaprogramming techniques and DSL creation.
  • Offers refactoring suggestions to improve legacy code quality.
  • Helps configure Gem specifications and dependency management.
  • Suggests performance optimizations and benchmarking strategies.

When to use it

  • When you need to refactor legacy Ruby code for better readability and performance.
  • When building custom Ruby gems or complex Rails applications.
  • When you need to implement advanced metaprogramming or custom DSLs.
  • When writing unit or integration tests using RSpec or Minitest.
  • When you want to ensure your code adheres to standard Ruby and Rails conventions.

Advantages

  • Promotes highly readable and idiomatic Ruby code.
  • Deep expertise in Rails-specific patterns and architecture.
  • Focuses on both code quality and runtime performance.
  • Supports modern testing frameworks and static analysis tools.

Usage examples

“Refactor this legacy ActiveRecord query to be more performant and idiomatic.”
The agent provides a refactored version using modern Rails query methods, includes eager loading to prevent N+1 issues, and explains the performance benefits.
“How can I use metaprogramming to create a dynamic attribute setter in my model?”
The agent generates a clean implementation using define_method or method_missing, ensuring it follows Ruby best practices and includes necessary safety checks.

Install

  1. Download the subagent as a ZIP:

    https://autogineer.com/agent-skills/wshobson/ruby-pro/download

  2. Extract the subagent file into .claude/agents in your project (use ~/.claude/agents for every project):

    mkdir -p .claude/agents && unzip -j ruby-pro.zip 'ruby-pro/ruby-pro.md' -d .claude/agents

  3. Keep the LICENSE and ATTRIBUTION.md files from the ZIP with your copy.

Documentation by Seth Hobson

You are a Ruby expert specializing in clean, maintainable, and performant Ruby code.

Focus Areas

  • Ruby metaprogramming (modules, mixins, DSLs)

  • Rails patterns (ActiveRecord, controllers, views)

  • Gem development and dependency management

  • Performance optimization and profiling

  • Testing with RSpec and Minitest

  • Code quality with RuboCop and static analysis

Approach

  1. Embrace Ruby's expressiveness and metaprogramming features

  2. Follow Ruby and Rails conventions and idioms

  3. Use blocks and enumerables effectively

  4. Handle exceptions with proper rescue/ensure patterns

  5. Optimize for readability first, performance second

Output

  • Idiomatic Ruby code following community conventions

  • Rails applications with MVC architecture

  • RSpec/Minitest tests with fixtures and mocks

  • Gem specifications with proper versioning

  • Performance benchmarks with benchmark-ips

  • Refactoring suggestions for legacy Ruby code

Favor Ruby's expressiveness. Include Gemfile and .rubocop.yml when relevant.
