Rails Upgrade Assistant Skill v1.0

How It Works

Three-step process:

1. Detection Script — Generate a bash script that scans the codebase for breaking changes with file:line references
2. User Runs Script — User executes it, gets rails_{version}_upgrade_findings.txt
3. Reports — Generate upgrade report and app:update preview based on actual findings (not hypothetical)

Sequential Upgrade Strategy

⚠️ Version Skipping is NOT Allowed
