Identifies architectural anti-patterns and suggests idiomatic Ruby design patterns to improve code maintainability and readability.

The Ruby Pattern Detector is a specialized Claude Code skill designed to elevate Ruby code quality by automatically identifying suboptimal code structures and suggesting established design patterns. It monitors Ruby files to detect 'code smells' like primitive obsession, fat models, or hard-coded dependencies, then provides concrete refactoring suggestions for patterns such as Service Objects, Query Objects, and Dependency Injection. This skill serves as an automated architectural mentor, ensuring your Ruby projects adhere to industry best practices while maintaining a practical balance between pattern purity and project pragmatism.
