ruby-pattern-detector

Pattern detection in Ruby identifies recurring design structures like Data Objects, Value Objects, and Null Objects in your codebase. This Skill scans Ruby files and suggests refactoring opportunities to improve design and maintainability by applying proven patterns.

The detector recommends Data Object patterns with builders and serialization, Loggable modules for centralized logging, Custom Exceptions, Dependency Injection, Value Objects, and Null Objects. Each recommendation includes concrete templates and example implementations for your code.

Yes, pattern detection works during code reviews to suggest design improvements and refactoring ideas. Run the detector on Ruby files when reviewing code to identify opportunities for applying best practices and standardized patterns across your project.

The detector requires bundler for dependency management and jq for processing output. Run it on a Ruby project directory to receive pattern recommendations and refactoring suggestions in structured format.

Pattern detection improves maintainability by identifying where standard Ruby patterns should be applied, reducing inconsistency and technical debt. Implementing suggested patterns creates predictable, well-organized code that teams can understand and modify more easily.
