SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill streamlines the creation of reusable code modules (concerns) in Rails applications by enforcing a Test-Driven Development (TDD) workflow, ensuring code quality and maintainability.

Core Features & Use Cases

TDD Workflow: Guides users through writing failing specs before implementing the concern.
Model & Controller Concerns: Provides examples and structure for both types of Rails concerns.
Common Patterns: Includes pre-built examples for UUID generation, soft deletion, searchability, auditing, and controller filtering.
Use Case: When you find yourself repeating the same validation logic across multiple models, use this Skill to generate a Validatable concern, write its tests first, and then include it in your models.

Quick Start

Use the rails-concern skill to generate a new concern named 'Auditable' for your Rails application.
