Incident Postmortem Writer

What this skill does

This skill turns a raw incident timeline, Slack thread dump, or bullet-point notes into a polished, blameless postmortem document. It structures the narrative, extracts action items, identifies contributing factors (not culprits), and formats everything into a document that can be shared with the team and used to prevent future recurrences. The output follows SRE best practices for blameless postmortems.

Use this immediately after an incident is resolved, while details are fresh, to produce the postmortem document without spending hours writing it from scratch.
