Skill Rails Upgrade

This handles the tedious parts of Rails upgrades by checking your current version against the latest release, pulling the official upgrade guide and railsdiff changes, then giving you a concrete assessment of what you're dealing with. It checks JavaScript dependencies too, which is nice since those often get overlooked. The best part is it specifically warns you not to blindly run rails app:update and instead walks through selective file merging so you don't clobber your customizations. Use it when you're planning an upgrade and want to know if you're looking at an afternoon or a week of work. It won't do the upgrade for you, but it does the research legwork and gives you an honest complexity rating.

Rails Upgrade Analyzer

Analyze the current Rails application and provide a comprehensive upgrade assessment with selective file merging.

Assessment is read-only by default. Dependency changes, generated files, migrations and application startup require the requested implementation scope. Confirm the database/environment before running application commands; use a disposable development database and tested restore for migrations.
