Is it suitable for enterprise Rails apps?

Yes, the skill is part of an enterprise-grade workflow and focuses on production-ready standards, including batch processing for large datasets and safety-assured migration practices.

How does this skill help with N+1 queries?

It provides standardized patterns for using eager loading techniques like includes, preload, and eager_load, along with clear documentation on when to use each loading strategy to avoid common performance pitfalls.

Does it support PostgreSQL-specific features?

Yes, it includes specific patterns for JSONB columns, GIN indexes, and safe concurrent migrations tailored for PostgreSQL databases.

What versions of Rails does this support?

While optimized for modern Rails (7.x+), the core ActiveRecord and SQL optimization patterns are applicable to most recent Rails versions.

Can I use this for complex business logic?

Absolutely. The skill includes a Query Object pattern specifically designed to isolate complex query logic from models, making your codebase more modular and testable.
