Stage and commit safely when several agents or people share one working tree, so no one absorbs another owner's in-flight work. Use before any git add or git commit in a checkout that other agents are editing concurrently.
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
# Git In A Shared Checkout The index is shared state. Two agents editing disjoint files are fine; two agents touching the index are not. ## Give Each Bounded Change One Staging Owner - Assign one explicit staging/commit owner per bounded change. Other agents may inspect or edit disjoint files, but they must not stage or commit while that owner is active. - Immediately before staging, and again before committing, the owner must inspect the index and working tree, stage only the named paths, and stop if an unexpected staged path or an overlapping edit appears. - Never use a shared `git add -A`, amend another agent's commit, or reset the shared index to repair a collision. - A validation run across a populated index is a collision window, and the other owner's next commit will absorb whatever is sitting there. ## Stage And Commit As One Action `git add` followed by a separate `git commit` is two actions, and another owner's commit can land between them however fast you are. That absorbed two agents' work in one day, one of them a 417-line file that ended up inside an unrelated commit. So either run validation *before* staging, or hold the change unstaged until the …

How to install
mdr add uchicago-dsi/ai-sci-skills/shared-checkout-git@sha256:bbf67bda4b69ece5The line at the top of this page pins the label git:20260922.57040a2, 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.
