Preserve rollback before materially risky edits.
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 Safety Checkpoint Use this skill before risky edits. The goal is simple: make sure there is a credible way back before changing files. ## Trigger Use when: - the user asks for website, app, repo, or code changes with nontrivial blast radius - files may be deleted, moved, regenerated, overwritten, or mass-edited - the repo has uncommitted changes - the work touches shared behavior, routing, deployment config, generated assets, or build tooling - the user specifically asks for backup, checkpoint, rollback protection, or protection from accidental destructive changes Do not run heavy backup steps for tiny read-only analysis or single-line edits unless the user asks. ## Workflow 1. Inspect state before editing. - Run `git status --short --branch` when inside a git repo. - Identify changed files that already exist before your work. - Treat uncommitted user changes as protected. 2. Choose the rollback path. - Follow the current repository/worktree branch policy. Record a recoverable base commit for tracked data; a branch label alone does not preserve uncommitted or untracked files. …

How to install
mdr add thegoat395/codex-skills/code-change-safety-checkpoint@sha256:da8ebbc8dc0e19b2The 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.
