Analyze Rails apps and provide upgrade assessments
Use this skill when working with analyze rails apps and provide upgrade assessments.
Analyze the current Rails application and provide a comprehensive upgrade assessment with selective file merging.
Check that we're in a Rails application by looking for these files:
Gemfile (must exist and contain 'rails')config/application.rb (Rails application config)config/environment.rb (Rails environment)If any of these are missing or don't indicate a Rails app, stop and inform the user this doesn't appear to be a Rails application.
Extract the current Rails version from:
Gemfile.lock for the exact installed version (look for rails (x.y.z))Gemfile for the version constraintReport the exact current version (e.g., 7.1.3).
Use the GitHub CLI to fetch the latest Rails release:
gh api repos/rails/rails/releases/latest --jq '.tag_name'
This returns the latest stable version tag (e.g., v8.0.1). Strip the 'v' prefix for comparison.
Also check recent tags to understand the release landscape:
gh api repos/rails/rails/tags --jq '.[0:10] | .[].name'
