What is a blameless postmortem?

A blameless postmortem is a document that focuses on systemic factors and technical improvements rather than individual human error, encouraging honest reporting and better long-term fixes.

Can I customize the focus of the postmortem?

Yes, you can provide optional arguments to the skill to specify a particular focus or add additional context not captured in the immediate conversation.

How does this skill extract the incident timeline?

The skill analyzes the conversation history, timestamps, and investigation steps taken during the resolution process to reconstruct an accurate sequence of events.

Where does the skill save the final report?

It will either update the postmortem section of an existing INCIDENT.md file or generate a new markdown file with a timestamp (e.g., POSTMORTEM-2023-10-27.md).

Generates comprehensive, blameless incident postmortems to document root causes and systemic improvements after resolving technical issues.

This skill automates the creation of professional post-incident documentation by analyzing the investigation context, evidence, and fixes discussed during an incident resolution session. It adheres to SRE best practices by enforcing a blameless philosophy—focusing on systemic failures and process gaps rather than individual errors. By extracting timelines, conducting a 5 Whys analysis, and identifying concrete follow-up actions, it helps teams transform outages into valuable learning opportunities while maintaining a structured history of system reliability in your repository.
