Clean up after (or abandon) a Rails upgrade. Drop NextRails.next? and NextRails.current? branches and retire dual-boot scaffolding (Gemfile.next, Gemfile.next.lock, conditional Gemfile groups), keeping either the next or the current version. Trigger when the user says they are done with the upgrade, want to clean up dual-boot, want to drop NextRails branches, want to finish the upgrade, want to abandon or revert the upgrade attempt, want to roll back to the current Rails version, or want to…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Upgrade Cleanup Skill

Companion to the `rails-upgrade` plugin. Runs the cleanup pass that removes dual-boot scaffolding and aligns the codebase to the new version baseline.

When activated, follow the workflow in `workflows/upgrade-cleanup-workflow.md` end-to-end. **Before any destructive step, confirm direction with the user** (Phase 0 Step 1): are they keeping the **next** version (finishing the upgrade) or keeping the **current** version (abandoning or pausing this hop)? Every subsequent step branches on that answer. To detect the next version, read the `Gemfile` (look for the `if NextRails.next?` / `else` block; the `next?` branch holds the upgraded-to version) or `Gemfile.next.lock`. Do NOT rely on `Gemfile.lock` alone, since during dual-boot it still pins the current version.

## When to Run

Run when the user has explicitly decided to **end the dual-boot phase** in one of two directions:

- **Keep next**: upgrade is done (final hop or stopping point), drop the `else` / current branches.
- **Keep current**: abandoning or pausing this hop, drop the `if NextRails.next?` / next branches and `Gemfile.next*`.

How to install

The exact contents, by fingerprint
mdr add ombulabs/claude-code_rails-upgrade-skill/upgrade-cleanup@sha256:eab46b861c7996e2

The line at the top of this page pins the label git:20260430.903cd29, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
