## TL;DR

Agents diagnosing production incidents need postmortems, incident timelines, root-cause writeups, and follow-up action items before treating a failure as understood.

## Core Explanation

Postmortems are high-value agent evidence because they connect symptoms to impact, mitigations, root causes, and prevention work. They also show which fixes were actually owned and tracked after an incident.

Agents should not summarize a postmortem as blame assignment. They should extract incident date, affected systems, trigger, detection path, recovery steps, contributing causes, action items, owners, tracking bugs, and whether similar incidents recurred.
