Incident postmortem prompt builder
A good postmortem turns an outage into prevented future outages — but writing one under post-incident fatigue is when corners get cut. This builder takes your raw incident facts and generates a prompt that produces a blameless, structured postmortem: summary, quantified impact, timeline, 5-whys root cause, contributing factors, what went well, and owned action items tagged by type.
How it works
You provide the incident summary, timeline events, contributing factors, and
impact metrics. The tool assembles a prompt instructing the model to write a
systems-focused, blameless report with a fixed section structure, to distinguish
the trigger from the underlying root cause using 5-whys, and to tag each action
item as prevent, detect, or mitigate. Crucially it tells the model not to invent
events or metrics and to mark gaps as [TODO: confirm], so the draft stays
grounded in what actually happened. The prompt is built in your browser.
Tips and notes
- Ground it in facts. The more accurate your timeline and impact data, the less the model has to mark as TODO and the better the root-cause analysis.
- Push past the trigger. The 5-whys instruction stops the report at the systemic cause, not just the immediate event.
- Balance the action items. Aim for coverage across prevent, detect, and mitigate — not five prevention tasks and nothing else.
- The owner signs off. The model drafts; the incident owner verifies the timeline and root cause and owns the follow-ups.
