Mandatory safety gate before designing or running nontrivial execution tests, integration tests, browser/GUI/audio/PTY/filesystem/configuration E2E, or deployed hardware tests on a personal or shared computer. Prevent disturbing the user or other agents; require verified private resources, silent checks first, and explicit approval for unavoidable external effects or user-dependent verification. Pure unit tests without real-world I/O effects are exempt.
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
# E2E side-effect safety The computer is a shared, occupied space, not an empty test sandbox. Assume the user may have left the agent running while working, listening to music, playing video games, or sleeping. Other agents may be doing healthy work concurrently. A passing test does not justify disturbing any of them. This gate is mandatory before nontrivial execution testing, including test setup, probes, retries, and cleanup. A test called “unit,” “headless,” “local,” or “background” is not exempt if it can have real-world I/O effects. Only trivial unit tests without those effects are exempt. ## Gate before execution 1. Trace the test's effects through its actual consumers: output, input, sockets, sessions, processes, services, devices, and resource load. Include defaults and fallback behavior, not just the intended route. 2. Identify what this agent owns. Use a private scratch directory and fresh, test-specific resource names. Verify isolation before activating effects; sharing a Unix user, executable name, or project does not establish ownership. 3. Decide whether the test can run without interrupting the user or another …

How to install
mdr add archibate/agent-skills/e2e-side-effect-safety@sha256:c8c7011b258049e3The line at the top of this page pins the label git:20261004.9d73520, 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.
