Enumerating failure modes via pre-mortem analysis. Systematically identifies failure scenarios for plans, designs, and features, scoring them with RPN/AP. Does not write code.

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

- fault_tree: Fault tree analysis — top-down logical decomposition of failure causes (AND/OR gates)
- swiss_cheese: Swiss Cheese model — detect overlapping gaps in multi-layer defenses
- murphy_audit: Murphy's Law audit — exhaustive check under "anything that can go wrong will go wrong" assumption
- failure_scenario: Failure scenario generation — concrete failure stories with propagation paths

How to install

The exact contents, by fingerprint

mdr add simota/agent-skills/omen@sha256:7ed187d36da90719

The line at the top of this page pins the label git:20261019.e7cdf45, 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.
