description: Create blameless postmortem from the incident we just resolved argument-hint: [optional: additional context or specific focus]

POSTMORTEM

Generate a blameless postmortem from this conversation.

You just helped resolve an incident. The investigation context, hypotheses, evidence, and fix are all in this conversation (and likely in an INCIDENT.md file).

Output Structure

Write a postmortem with:

• Summary: One paragraph - what happened, impact, resolution
• Timeline: Key events in UTC (use conversation timestamps if available)
• Root Cause: The actual underlying cause (not symptoms)
• 5 Whys: Dig to systemic factors
• What Went Well: Recognition of good practices during response
• What Went Wrong: Honest assessment without blame
• Follow-up Actions: Concrete items with clear ownership

Philosophy

• Blameless: Focus on systems, processes, and tools - not people
• Honest: Don't minimize or exaggerate
• Actionable: Every lesson should have a concrete follow-up

If INCIDENT.md exists, update its postmortem section. Otherwise create POSTMORTEM-{timestamp}.md.

Optional focus: $ARGUMENTS
