Make containment decisions before scope is known, reasoning in reversible-versus-irreversible moves — because acting tips off the adversary (they burn down, accelerate, or pivot) while not acting lets the bleed continue, and "we don't fully understand it yet" must never quietly become "so we did nothing." Use in an active incident when the question is what to do now with incomplete information: "should we isolate the host", "pull it off the network", "rotate all credentials…
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
# Containment Under Uncertainty The defining condition of containment is that you must act before you know the scope, and both acting and waiting cost you something. Evict too early and loudly and you warn the adversary — who then burns their access down, destroys evidence, or accelerates to finish the job before you finish yours. Wait for certainty and the data keeps leaving. There is no move that is free of one of these costs, so the discipline is not "decide once you understand it"; it is **buy information without buying disaster**, and reason about every action as reversible or irreversible. The two failure modes are symmetric, and organizations reliably pick one by temperament: - **Premature loud eviction.** Pulling the plug, mass-resetting, wiping the box — before you know what it connected to. You destroy the forensic scope you needed (`what else did this credential touch?` is now unanswerable), and you tell the intruder you are onto them while they still hold three other footholds you never found. - **Analysis paralysis.** "We don't fully understand it yet" hardens into inaction while exfiltration continues. Perfect scope is never available during the bleed; the …

How to install
mdr add annatchijova/skills/containment-under-uncertainty@sha256:92631dd07c43df27The line at the top of this page pins the label git:20260825.8500180, 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.
