Restore requested code changes or checkpoints.
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
# Code Change Undo And Revert Use this skill when the user wants to go back safely. The job is to identify what changed, preserve user work, and choose the least destructive undo path. ## Trigger Use these phrases only when the surrounding request establishes code/repository rollback intent: - undo - revert - roll back - restore - recover - go back to before - remove your changes - bring back deleted code - compare against the checkpoint ## Workflow 1. Inspect the current state. - Run `git status --short --branch` when in a git repo. - Review changed files before reverting anything. - Identify whether changes are yours, the user's, generated output, or mixed. 2. Choose the safest target. - If the user wants only your latest edits undone, revert only those files or hunks. - If the user wants a branch or commit reverted, inspect the commit range first. - If a local backup exists, compare backup files before copying anything back. 3. Avoid broad destructive commands. …

How to install
mdr add thegoat395/codex-skills/code-change-undo-revert@sha256:d7f6068fed40deb9The line at the top of this page pins the label git:20260905.f7824ba, 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.
