Perform comprehensive code audits of Ruby on Rails applications based on thoughtbot best practices. Use this skill when the user requests a code audit, code review, quality assessment, or analysis of a Rails application. The skill analyzes the entire codebase focusing on testing practices (RSpec), security vulnerabilities, code design (skinny controllers, domain models, PORO with ActiveModel), Rails conventions, database optimization, and Ruby best practices. Outputs a detailed markdown audit report grouped by category (Testing, Security, Models, Controllers, Code Design, Views) with severity levels (Critical, High, Medium, Low) within each category.
Use when writing or reviewing tests in a Ruby/Rails application. Guides agents to write well-structured tests using the Arrange/Act/Assert pattern, semantic Capybara selectors, and performance-aware practices.
Use when encountering bugs, test failures, or unexpected behavior. Provides a systematic debugging process based on surfacing assumptions, building decision tables, and validating one assumption at a time.
Use when writing or modifying code in a Rails application. Guides agents to follow thoughtbot best practices for N+1 prevention, view layer organization, and domain modeling.

Before refactoring, check each gate. If any gate fails, stop and do the suggested alternative instead.
Refactoring means behavior-preserving code changes — nothing more. If the behavior changes, it's not a refactor.
Refactoring = behavior-preserving changes only. If you're fixing a bug, adding a feature, or handling a new requirement, that's not refactoring — call it what it is.
If no: Stop. Discuss what system change is needed. Don't disguise feature work as refactoring.
If the improvement matches "almost all" cases but creates exceptions, don't force the abstraction. Three similar lines of code is better than a premature abstraction with an exception.
If no: Investigate a different code smell, or wait for a new requirement that makes the pattern clearer.
Never do two refactors simultaneously. Creating a method AND removing a variable is two refactors. Complete one fully — save, test, commit — before starting the next.
If yes: Finish the current refactor first. Commit it. Then start this one.
Target code that is both complex AND changes frequently. There's no benefit to improving code that never changes. Check git history — if the file hasn't been touched in months, skip it.
Watch for wishful thinking: convincing yourself code won't change because you can't see how to improve it.
If no: Find more changeable code to refactor, or pause refactoring entirely.
Without tests, you cannot guarantee behavior is unchanged. If you change behavior without knowing it, you're not refactoring — you're introducing bugs.
If no: Write tests first. Tests help you learn about the code, and once they exist, you can refactor safely.
If you find something you don't understand mid-refactor, stop. If you've been using small steps, the tidying done so far is safe to keep or easy to revert.
If yes: Pause. Continue later when you understand more. Martin Fowler: refactoring is "a series of small behavior-preserving transformations" — each one should be safe on its own.
