rails-load-defaults

Incrementally upgrade Rails `config.load_defaults` by walking through each new_framework_defaults config one at a time. Use this skill whenever the user mentions load_defaults upgrade, new_framework_defaults, framework defaults, or wants to bring their Rails app's default configuration up to match their Rails version. Also trigger when the user mentions a gap between their Rails version and their load_defaults version (e.g., "app is on Rails 7.2 but load_defaults is 6.1"). This skill handles the iterative uncomment-test-commit workflow and the final consolidation into config/application.rb.

适合你，如果正在升级 Rails 版本并需要逐步调整默认配置。
