## When to use this skill

- When adding `rescue_from` blocks in `ApplicationController`
- When creating custom error pages (`public/404.html`, `public/500.html`)
- When deciding between `find` (raises) and `find_by` (returns nil)
- When handling `ActiveRecord::RecordNotFound` or `ActionController::ParameterMissing`
- When implementing validation failure responses
- When rendering error status codes (`:not_found`, `:unprocessable_entity`)
- When configuring error tracking services (Sentry, Honeybadger)
- When implementing graceful degradation for external service failures
