SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill eliminates the risk of inconsistent, low-quality Rails code reviews that miss hidden regressions, unnecessary complexity, and convention breaks that make codebases increasingly hard to maintain over time.

Core Features & Use Cases

  • Conditional Rails-specific review: Activates only when diffs touch Rails application code, avoiding irrelevant feedback for non-Rails changes.
  • Strict maintainability focus: Flags existing-file complexity that adds no value, hidden regressions in refactors, Rails clarity failures, hard-to-test code structure, and overbuilt abstractions.
  • Calibrated confidence scoring: Assigns clear confidence levels to findings, prioritizing high-impact issues and suppressing low-value stylistic criticism.
  • Use Case: For example, when reviewing a PR that modifies a Rails controller with Turbo streams, this Skill will flag if the stream response uses separate templates when inline render arrays would be simpler, or if a refactor removed a callback without preserving existing behavior.

Quick Start

Use the kieran-rails-reviewer skill to review the latest Rails code diff for maintainability risks and convention breaks.

FAQPage Schema
How do I catch hidden regressions and convention breaks in a Ruby on Rails pull request?

To catch hidden regressions in a Ruby on Rails pull request, apply a strict code review to the diff that flags unnecessary complexity, removed callbacks without preserved behavior, and convention breaks to prevent long-term technical debt.

What is the best way to enforce maintainability standards when reviewing Rails controllers and models?

Enforcing maintainability standards for Rails controllers and models requires flagging overbuilt abstractions, hard-to-test code structures, and Rails clarity failures. A calibrated confidence score prioritizes high-impact issues while suppressing low-value stylistic criticism.

Does this Rails code review approach work with Turbo and Hotwire stream changes?

Yes, this Rails code review approach works with Turbo and Hotwire stream changes by flagging unnecessary complexity in stream responses. It identifies when inline render arrays would be simpler than separate templates in your pull request workflows.

How do I automate flagging unnecessary complexity in Rails service objects?

Automate flagging unnecessary complexity in Rails service objects by reviewing code diffs for existing-file complexity that adds no value. This strict review catches overbuilt abstractions and hard-to-test code structures to reduce technical debt.

Can I use this code review skill for non-Rails Ruby application changes?

No, you should not use this code review skill for non-Rails Ruby application changes. The conditional review logic activates only when diffs touch Rails application code, specifically controllers, services, models, and Turbo/Hotwire patterns.
