# Incident Postmortem Skill
This skill produces a complete, blameless incident postmortem document following industry-standard format. Output enforces blameless framing throughout — system gaps over individual failures — and drives toward specific, closeable action items rather than vague process commitments.
## Required Inputs
Ask the user for these if not provided:
- **Incident title / ID**
- **Severity** (P1 / P2 / P3 or SEV1 / SEV2 / SEV3)
- **Date and duration** of the incident
- **What happened** (rough notes are fine — the skill will structure them)
- **Services or systems affected**
- **Customer impact** (how many users, what was degraded)
- **How it was detected**
- **How it was resolved**
- **Initial thoughts on root cause**
- **Action items already identified** (optional)
- **Responders** (who was on-call or responded — names or roles; used for the timeline, not for blame)
- **Customer or external communications sent** (optional — any status page updates, emails, or support messages with timestamps)
