Can it help with major version upgrades like Rails 7 to 8?

Absolutely. It pulls the official Rails upgrade guides and provides a complexity assessment (Small, Medium, Large) based on the specific version jump and identified breaking changes.

What external tools are required for this skill?

The skill utilizes the GitHub CLI (gh) for version tracking and WebFetch to pull real-time data from the official Rails guides and RailsDiff.org.

How does this differ from the standard 'rails app:update' command?

Unlike the native command which often overwrites files and erases local changes, this skill performs a selective merge. it identifies your customizations and helps you integrate new Rails defaults without losing existing project logic.

Does it handle JavaScript and Hotwire dependencies?

Yes, it analyzes package.json or importmap.rb to ensure packages like Turbo, Stimulus, and ActionCable are updated in lockstep with the Rails framework version.

Developer Tools

Automates Ruby on Rails upgrades through version assessment, dependency analysis, and selective configuration merging.

The Rails Upgrade Analyzer is a comprehensive tool designed to simplify the complex process of upgrading Ruby on Rails applications. It bridges the gap between official upgrade guides and manual implementation by analyzing current versions, identifying breaking changes, and performing selective file merges that preserve local customizations. By leveraging external resources like RailsDiff and the GitHub API, this skill provides developers with a step-by-step roadmap and automated checks for both Ruby gems and JavaScript dependencies, ensuring a safe, structured, and non-destructive transition to newer framework versions.
