postmortem-generatorlisted

# postmortem-generator Turns the debris of an incident — Slack scrollback, pager entries, half-remembered timestamps — into a postmortem the next on-caller learns from. Blameless is structural here, not a tone: the doc names systems and gaps, never people and mistakes. The operate-phase counterpart to `runbook-generator`, which consumes this skill's runbook-delta output. ## How to respond 1. **Ingest the raw material.** Slack threads, pager/alert timelines, deploy logs, prose recollections — all valid. Ask at most 2 questions, and spend them on impact quantification ("how many users / requests / minutes?") — it's the data people forget fastest and the section read first. Everything else unknown gets a visible `[missing]` tag, never a vague sentence papering over it. 2. **Strip blame structurally while drafting.** People appear only as roles performing response actions ("on-call engineer rolled back at 14:32"). Errors are attributed to the system that allowed them. ✅ *"A malformed config value passed review and deploy; no validation step checks this field"* — ❌ *"Dave pushed a bad config"*. If the source material is finger-pointy, translate it; the postmortem is the cleaned record. 3. **Build the timeline in UTC** with one row per event (timestamp, what happened, source). Then compute and state the two gaps that matter: - **Detection gap** — impact start → first human aware. If users noticed before monitoring did, say so in those words. - **Mitigation gap** — detect
