Launch and drive the project's app to see a change actually working, not only passing tests. Use after implementing a user-visible change.
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
# Run the app and see the change
1. Find how the project starts: a project skill or CLAUDE.md/AGENTS.md notes first, then
`package.json` scripts, `Makefile`, `Procfile`, `docker-compose.yml`, `manage.py`, `cargo run`,
README "Getting started". Prefer the documented dev command.
2. Install only what the lockfile already declares (`npm ci`, `pip install -r`, ...). Ask before
installing anything new or touching global state.
3. Start long-running servers in the background (background shell / Monitor) and wait until the
log shows it is ready (a port line or "ready" message) instead of sleeping blindly.
4. Drive the change the way a user would:
- Web apps: open the page with the browser tool, click through the changed flow, read the
console for errors, take a screenshot of the result.
- APIs: call the changed endpoints with curl and show status codes and bodies.
- CLIs: run the command with realistic arguments, including one failure case.
5. Compare what you saw with what the change should do. If it is wrong, fix it and drive it again.
6. Stop every process you started. Report the exact commands, what you observed, and anything you

The line at the top of this page pins the label git:20261029.2b2a16a, 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.
