How does it handle external API dependencies in tests?

The skill enforces the use of VCR for all external HTTP calls, ensuring your test suite remains fast, deterministic, and offline-capable.

Does it automatically overwrite my existing code?

No, the skill is designed to provide detailed implementation plans for review first, only writing code once it has been explicitly approved.

What design philosophy does the Rails Expert skill follow?

It follows Practical Object-Oriented Design in Ruby (POODR) by Sandi Metz and Martin Fowler’s refactoring patterns to ensure code is flexible and maintainable.

Does this skill support FactoryBot?

This specific skill prioritizes the use of standard Rails fixtures over factories to ensure faster test execution and closer adherence to Rails conventions.

Can it help with frontend or browser testing?

Yes, it provides specific guidance for system specs using Capybara and Cuprite for modern, headless browser testing.

API Development

Standardizes Ruby on Rails development by applying POODR principles and modern refactoring patterns for high-quality, maintainable codebases.

The Rails Expert skill transforms Claude into a senior-level Ruby on Rails architect specializing in Object-Oriented Design and idiomatic coding practices. It enforces strict architectural standards based on Sandi Metz’s POODR and Martin Fowler’s refactoring techniques, ensuring small methods, flat inheritance hierarchies, and clean dependency injection. Beyond code structure, it provides a comprehensive testing philosophy prioritizing RSpec fixtures, Cuprite for system specs, and VCR for external calls, helping developers build scalable, test-driven Rails applications while avoiding common pitfalls like duplicate logic or bloated classes.
