Does it assist with N+1 query detection?

Yes, it includes detection patterns for identifying multiple queries for the same association and provides implementation strategies for Eager Loading.

Can it help with ActiveRecord grouping errors?

Yes, it provides specific rules for PostgreSQL compatibility, ensuring all non-aggregated columns in a SELECT statement are correctly included in the GROUP BY clause.

How does this skill prevent ViewComponent errors?

It provides a verification process to ensure methods called in views are explicitly exposed in the component class and confirms template existence before execution.

When should I use the Rails Error Prevention skill?

Review this skill before creating ViewComponents, writing complex ActiveRecord queries, or adding new controller actions to apply preventative quality gates.

Prevents common Ruby on Rails runtime errors and architectural pitfalls through proactive checklists and automated verification patterns.

概要

This skill enhances the Rails development process by implementing a 'check-before-coding' philosophy to eliminate frequent bottlenecks like ViewComponent template mismatches, PostgreSQL grouping errors, and N+1 queries. It provides developers with domain-specific guidance on method exposure, helper delegation, and ActiveRecord query optimization, ensuring that enterprise-grade Rails applications remain stable and maintainable. By integrating these quality gates into the development workflow, Claude can assist in catching 'undefined method' or 'missing template' errors before they ever reach a staging environment.
