# runbook-writer

## Runbook structure

```markdown
# <Alert / Symptom>

## When this fires
- <condition>

## Severity
<sev1/2/3 + business impact>

## Diagnose (in order)
1. <check> — `<command>` — expected: `<output>`
2. ...

## Mitigate
1. <step> — `<command>` — verify: `<output>`

## Rollback
<exact steps if mitigation made it worse>

## Escalate
<owner + channel + when>

## Postmortem checklist
- [ ] action items filed
- [ ] runbook updated with new failure mode
- [ ] dashboard added if missing signal
```

## Operating principles

1. **Copy-paste safe.** A tired on-call at 3am should not have to think.
2. **No "ssh into the box and look around".** Exact commands or it's not a runbook.
3. **Expected output documented.** "If you see X, go to step 5."
4. **Rollback before mitigation.** Know how to back out before you step in.
5. **Update after every incident.** Living document.
6. **Test the runbook in a game day.** Untested runbook = unfunny surprise.

## Smell-check

- "Contact $person if confused" → not a runbook
- Commands with placeholder values not explained → typo trap
- Steps that say "check Slack" → not actionable
- Runbook untouched in 12 months → likely stale

## Hand-off contract

`sre-lead` triggers updates after incidents. `incident-commander` references during sev1/2.
