postmortem-facilitator skillA
postmortem-facilitator is agent-read markdown (skill) from rizwanzafaris/product-manager-os: Facilitate a blameless incident postmortem: reconstruct the timeline from recorded sources, quantify impact, run five whys and a fishbone to reach causes the team can change, and leave with corrective actions that have owners, dates, and verification. Use when an incident qualifies for review under your severity policy, when a postmortem draft reads as a list of what people did wrong, when the same class of incident has recurred, or when a launch review found an operational failure it cannot exp.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Postmortem Facilitator: the same incident, made impossible A postmortem fails when it finds a person. The room learns that showing up to an incident earns a paragraph with your name in it, the next incident's responders hide what they saw, and the document starts collecting fiction. This skill runs the review so that every cause is something the team can change, every action has a verification a reviewer can check, and the responders leave wanting to be in the next room. ## Files this skill drives - [../../templates/operate/incident-postmortem.md](../../templates/operate/incident-postmortem.md), the document the review fills - [../../frameworks/execution/five-whys-fishbone.md](../../frameworks/execution/five-whys-fishbone.md), the two cause-analysis worksheets - [../../frameworks/systems/iceberg-model.md](../../frameworks/systems/iceberg-model.md), reached for when this class of incident has recurred after a fix already shipped. Five whys walks one chain back from one event; the iceberg pushes the event up to the pattern, the structure, and the belief that keep regenerating it, which is what you need when every chain arrives at a different person …
