Write a blameless incident postmortem a manager can trust: a verified timeline, quantified impact, a root cause that survives five whys, and action items with one owner and one date each.

Try it

Using incident-postmortem-writer, write the postmortem for last night's checkout outage: the payment credential expired, the alert fired at 14:02 UTC, rollback completed at 14:31 UTC. Timeline and impact numbers are in the notes below.

What you get

A complete postmortem in one pass: a verified timeline with sources, an impact table with sourced numbers, a five-whys root cause that ends at a system cause rather than a person, action items covering prevent, detect and mitigate — each with one owner, one due date and one verification step — plus a draft customer paragraph for human approval. Delivered as a full skill: 7-step workflow, blameless-writing rules, QA checklist and 3 reference guides.

Good fit

Engineering teams, on-call engineers and managers who owe a written record after an outage, failed deploy or data incident — and teams that have had the same incident twice because the last postmortem's action items had no owner.

Not for

Teams in the middle of an active incident (respond first, write later); anyone looking for a formal legal or liability report; anyone who wants the document to assign blame to a person. Honest limit: a postmortem is only as good as its evidence — gaps are marked, never invented — and the customer paragraph is a draft that needs human approval before sending.
