Parallels macOS VM lab: GUI automation, Peekaboo, TCC, Ghostty.
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
# VM Lab Use this when the task needs a clean macOS VM to test GUI automation, TCC prompts, screenshot capture, clicking, typing, performance, or "two-way validation" of Peekaboo-like tools. Core idea: run the tool under test inside the guest, but verify it from outside the guest with Parallels screenshots and host-side observations. Do not close apps you do not own. ## Safety Rules - Only task-owned clones are disposable. Preserve source/golden snapshots, recovery VMs, and other tasks' VMs; never reset, revert, or delete their snapshots. - Never access inherited guest credentials or bypass login/startup security to bootstrap a clone. - Never print secrets. If `op` is needed, follow the 1Password skill and run it only inside `tmux`. - Prefer fresh app windows you create yourself: TextEdit, a local HTML test page, or a small test app. - Limit host writes to task-owned temporary diagnostics and explicitly authorized clone recovery. Never change global Bash/Codex settings for a lab workaround. - For git repos inside the VM, use HTTPS remotes and normal branch discipline. ## Bootstrap Preflight …

How to install
mdr add steipete/agent-scripts/vm-lab@sha256:2be04934b8399ceaThe line at the top of this page pins the label git:20260906.8cceb4f, 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.
