How to Use OpenClaw for Postmortems

Postmortems are easy to delay because the timeline is scattered and everyone is tired. OpenClaw can help by assembling the first draft while the evidence is still fresh.

Start with one decision, not the whole department

The goal is not to let the agent decide blame or root cause alone. The goal is to give the humans a structured starting point with the facts, timeline, and unresolved questions already laid out.

Start with one incident type, usually production issues. Gather the alert times, major decisions, deploy context, mitigations, and follow-up actions into a draft that responders can edit while memory is still intact.

openclaw cron add "30 9 * * *" "for incidents closed in the last 24 hours, draft postmortem timelines, facts, mitigations, and open questions" --name hex-postmortem-draft

Write the judgment rules down

Postmortem quality comes from separating evidence from interpretation.

## Postmortem Rules
- Use timestamps and source links whenever possible
- Separate facts, hypotheses, and final conclusions
- Include what reduced impact, not just what failed
- End with concrete follow-up owners and dates

If the agent does nothing else, that evidence split is worth a lot. It keeps the document honest and makes it easier for the team to argue productively instead of defensively.

Bring in source systems only after the baseline works

Pull from incident channels, PagerDuty, error tools, deploy logs, and any manual notes responders already captured. You do not need every system in the world. You just need enough sources to stop the team from reconstructing the same story from scratch.

Have the incident lead review each draft before it is shared. The draft should save time, not replace accountability. Humans still own the final root-cause call and the follow-up commitments.

Review misses and turn them into operating rules

The first few runs should absolutely be reviewed by a human. When OpenClaw gets something wrong, the fix is usually not more cleverness. The fix is a sharper rule about evidence, urgency, or output format. Each one of those lessons belongs in markdown so the workflow compounds instead of drifting.

I also like keeping one short memory file with examples of good and bad outputs. That gives the agent a local standard to imitate and makes future edits much easier than trying to remember every exception from scratch.

This is also where scope control matters. When teams get excited, they try to bolt on more automations before the core judgment is trustworthy. I would rather run one boring workflow well for a month than ship five flashy ones nobody actually relies on.

Make the output easy to act on

The best output is a timeline, impact summary, known cause or hypotheses, mitigation record, and action list. When the draft already contains that skeleton, finishing the postmortem becomes a real task instead of a vague guilt cloud.

Success means more postmortems actually get written, they are more factual, and follow-up actions stop disappearing after the incident adrenaline wears off.

When in doubt, shorten the output and sharpen the next action. Most workflow failures are not because the agent lacked intelligence. They fail because the human recipient could not tell what to do with the result.

That is why I prefer outputs with an owner, a deadline or cadence, and one recommended next move. The more specific the handoff, the more likely the workflow becomes part of real work.

It sounds simple, but simple is exactly what most teams need from automation.
