When is the best time to trigger this skill in Claude Code?

This skill is designed for use BEFORE writing code. Trigger it when planning a new ViewComponent, complex database query, or controller action to follow established best practices.

Does this skill assist with database performance?

It includes detection and prevention strategies for N+1 queries, providing clear examples of when to use 'includes', 'preload', or 'eager_load' versus simple associations.

How does this skill help with ViewComponent errors?

It provides a specific verification process to ensure methods called in views are explicitly exposed in the component class and validates template file locations to prevent 'Template Not Found' errors.

Can it prevent PostgreSQL grouping errors?

Yes, it provides strict rules and code patterns to ensure all non-aggregated columns in a SELECT statement are correctly represented in the GROUP BY clause, a common issue in Rails/Postgres environments.

Does it support modern Rails helper patterns?

セキュリティとテスト

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

The Rails Error Prevention skill serves as a preventative quality gate for Ruby on Rails development, specifically targeting frequent mistakes in ViewComponents, ActiveRecord queries, and controller actions. By implementing strict method exposure verification and template path validation before code is written, it helps developers avoid common 'undefined method' and 'template not found' errors. It provides structured implementation patterns for handling PostgreSQL grouping errors, N+1 queries, and nil-safety, ensuring enterprise-grade code quality and performance across complex Rails applications.
