How does this skill prevent N+1 queries in Rails?

The skill provides specific patterns for eager loading using .includes() and .joins(), and guides developers to implement counter caches for frequently accessed associations.

Is this skill compatible with modern Rails versions?

Yes, the patterns and checklists are designed for modern Rails (6.x and 7.x) and follow the latest enterprise-grade development standards.

Does this skill cover database migration safety?

Yes, it includes a checklist for creating reversible migrations, adding necessary foreign key indexes, and enforcing null constraints to maintain data integrity.

How does it help with Ruby NoMethodErrors?

It enforces nil-safety protocols, such as using the safe navigation operator (&.), presence validations, and explicit nil-handling in conditionals.

セキュリティとテスト

Enforces production-grade Ruby on Rails code quality through comprehensive safety checklists covering security, performance, and error handling.

概要

This skill provides an essential safety layer for Ruby on Rails development by enforcing enterprise-grade coding standards. It guides developers through critical checks for nil-safety, ActiveRecord optimization, SQL injection prevention, and migration integrity before code is finalized. Designed for the implementation phase of the development lifecycle, it helps prevent common bugs like N+1 queries and NoMethodErrors while ensuring the application remains secure, performant, and maintainable under production loads.
