Can I use this to refactor an existing gem?

Yes, it is highly effective at identifying anti-patterns like heavy DSLs or unnecessary dependencies and refactoring them into the Kane style.

How does it handle Rails integration without tight coupling?

It uses ActiveSupport.on_load hooks and Railtie patterns to ensure the gem integrates perfectly with Rails only when Rails is actually present.

Does this skill support RSpec for testing?

No, this skill specifically follows Andrew Kane's preference for Minitest to keep the gem's testing footprint small and fast.

What is the core philosophy of this Ruby gem skill?

The philosophy focuses on simplicity over cleverness, minimal dependencies, and explicit code over metaprogramming to ensure long-term production stability.
