Rails Upgrade
Overview
This skill provides a systematic workflow for upgrading Rails applications, covering versions 5.2 through the latest release. It fetches live configuration diffs from railsdiff.org via the GitHub API, performs direct codebase detection using Grep, Glob, and Read tools, and compiles structured upgrade reports — all without requiring external skill dependencies.
