To check Ruby code for Sandi Metz design violations, run the reviewer on a Ruby file to evaluate class and method sizes, parameter counts, instance variable limits, and Law of Demeter adherence. It returns structured feedback with severity levels and suggested refactorings aligned with POODR principles.

The four Sandi Metz rules for object-oriented design limit classes to 100 lines, methods to 5 lines, method parameters to 4, and instance variables per class to 4. This Skill enforces these rules alongside SRP and Law of Demeter checks to generate actionable refactoring guidance for Ruby projects.

Automate Ruby refactoring code review by applying this Skill to assess SOLID principles, specifically evaluating Single Responsibility and Tell Don't Ask patterns. It produces structured feedback with severity levels and actionable refactoring suggestions suitable for integration into developer workflows.

Yes, this code reviewer detects Law of Demeter violations in Ruby code. It evaluates dependency chains and object interaction patterns, reporting violations alongside SRP adherence and class size limits to provide structured, actionable refactoring feedback.

Yes, you can integrate POODR principles into automated developer workflows. This Skill produces structured feedback aligned with Sandi Metz's object-oriented design rules, assessing dependencies and method sizes to enable consistent code quality evaluation during code review.

Use a POODR-based reviewer instead of general Ruby code analysis when you need to enforce specific object-oriented design constraints like the four rules, Single Responsibility Principle, and Law of Demeter. It provides targeted refactoring guidance for dependency management rather than basic syntax or style checks.
