What architectural patterns does this skill implement?

It implements five primary patterns: Concerns for shared themes, Service Objects for business logic, Query Objects for complex database calls, Form Objects for validations, and Value Objects for domain concepts.

Will this skill help with unit testing?

Yes. By breaking a monolithic model into smaller, specialized classes like Service and Query objects, it makes individual components much easier to isolate and test.

When should I use the Rails Model Best Practices skill?

You should use this skill when a Rails model exceeds 100 lines of code, contains mixed responsibilities, or when you need to extract complex business logic into more manageable patterns.

How does it handle complex database queries?

It extracts complex joins, subqueries, and multi-condition filters into dedicated Query Objects that accept a base relation and return an ActiveRecord relation for continued chainability.

Refactors Ruby on Rails ActiveRecord models into modular, maintainable patterns like services, queries, and concerns.

This skill provides a structured framework for refactoring bloated Ruby on Rails models by extracting logic into specialized architectural patterns. It analyzes model files to identify business logic, complex queries, and context-specific validations, guiding the migration of code into Service Objects, Query Objects, Form Objects, Value Objects, or Concerns. By enforcing these guardrails, it ensures that ActiveRecord models remain thin and focused on core associations and validations, significantly improving code maintainability and testability in AI-assisted development workflows.
