majiayu000 Runbook Writer Skill
Produces operational runbooks for services, incident types, and deployment procedures — structured so an on-call engineer who's never touched the system can follow them under pressure.
Required Inputs
Ask for these if not provided:
- What the runbook is for (e.g. deploying the payment service, responding to a database failover, rotating API keys)
- Runbook type (Deployment / Incident Response / Maintenance / Disaster Recovery)
- System/service name and what it does (brief description)
- Audience (new on-call engineers / experienced SREs / DevOps team)
- Tech stack (where relevant — e.g. Kubernetes, AWS RDS, Node.js)
- Monitoring tools (e.g. Grafana, Datadog, CloudWatch, Splunk — used to name specific dashboards and alert links in the steps)
- Key environment details (e.g. Kubernetes cluster name, AWS account/region, relevant namespaces or resource names — paste what's relevant for exact commands)
Output Format
Runbook: [Runbook Title] Service: [Service Name] Type: [Deployment / Incident Response / Maintenance / DR] Last Updated: [Insert today's date in YYYY-MM-DD format] Owner: [Team or person] Severity: [P1 / P2 / P3 — if incident-type]
Overview
What this runbook covers: [1–2 sentences on the scenario this runbook handles]
When to use this runbook:
- [Specific trigger condition 1 — e.g. PagerDuty alert:
high-error-rate-payment-service] - [Specific trigger condition 2 — e.g. Deploy needed after PR merged to
main]
Estimated time to complete: [X minutes / X–Y minutes depending on outcome]
Impact if not completed correctly: [e.g. Payment processing degraded / Data loss risk / Users locked out]
Prerequisites
Access required:
- [System/tool access — e.g. AWS Console:
production-account] - [Credential — e.g.
vault read secret/payment-service] - [VPN / bastion access if needed]
Tools required:
- [Tool name and version — e.g.
kubectlv1.28+] - [CLI or dashboard name]
Before you start:
- [Prerequisite check — e.g. Verify current deployment is healthy in Grafana]
- [Prerequisite action — e.g. Announce in
#ops-livethat you're starting]
Procedure
Number every step. Use exact commands. Do not paraphrase tool names or flags.
Step 1: [Action name] [What you're doing and why — one sentence]
# Exact command
[command here]
Expected output: [what should appear if this worked]
If this fails: [Exact error message to look for] → [What to do, or see Troubleshooting]
Step 2: [Action name] [Same structure as Step 1]
Step 3: Verify Always include a verification step after the main procedure:
[verification command]
Expected state: [What a healthy system looks like after this runbook completes]
Rollback
How to undo this procedure if something went wrong:
Step R1: [Rollback action]
[rollback command]
Verify rollback: [command to confirm rollback succeeded]
Troubleshooting
| Symptom | Likely Cause | Resolution |
|---|---|---|
| [Error message or observable symptom] | [Why this happens] | [Exact fix or next step] |
| [Another symptom] | [Cause] | [Resolution] |
Escalation
If this runbook does not resolve the issue:
| Condition | Who to Contact | How |
|---|---|---|
| [e.g. DB unavailable after 10 min] | [DBA on-call] | [PagerDuty policy: db-oncall] |
| [e.g. Payment provider unresponsive] | [Vendor contact] | [Contact in 1Password: vendor-escalation] |
Always update the incident timeline in [tool] before escalating.
Post-Procedure Checklist
After completing the runbook:
- Announce completion in
#ops-livewith outcome - Update the incident ticket / deploy log
- Verify alerts have resolved in monitoring dashboard
- If this revealed a gap in this runbook — update it now (link to edit process)
Quality Checks
- Every step has an exact command (no "run the deploy script")
- Expected output is specified for each step so engineer knows if it worked
- Failure path is explicit for each step (not "if it fails, investigate")
- Rollback procedure is complete and independently testable
- Escalation table has no cells containing only "[Team name]" — every row must either have a real contact or be explicitly flagged as [FILL IN: on-call rotation link]
- Rollback section contains at least one concrete command (not left as "[rollback command]" placeholder)
- Runbook can be followed by someone who has never touched this system
Usage Examples
- "Write a runbook for [service] deployment"
- "Create an incident response runbook for [alert type]"
- "I need a runbook for [procedure]"
- "Document the operational procedure for [X]"
- "Write an ops playbook for [scenario]"
