Runbook Generator

Tier: POWERFUL Category: Engineering / SRE Maintainer: Claude Skills Team

Overview

Analyze a codebase and generate production-grade operational runbooks with copy-paste commands, verification checks after every step, rollback procedures for every destructive action, escalation paths with contact information, and time estimates for capacity planning. Detects the stack (CI/CD, database, hosting, containers) and produces runbooks tailored to the actual infrastructure. Includes staleness detection to flag runbooks when referenced config files change.

Keywords

runbook, operational procedures, incident response, deployment, rollback, database maintenance, scaling, monitoring, on-call, SRE, postmortem

Core Capabilities

1. Stack Detection

  • Identify CI/CD platform, database, hosting, and orchestration from repo files
  • Map detected stack to appropriate runbook templates
  • Extract connection strings, deployment commands, and infrastructure details

2. Runbook Types

  • Deployment: pre-checks, deploy steps, smoke tests, rollback
  • Incident response: triage, diagnose, mitigate, resolve, postmortem
  • Database maintenance: backup, migration, vacuum, reindex
  • Scaling: horizontal and vertical scaling procedures
  • Monitoring: alert setup, dashboard configuration, on-call rotation

3. Format Discipline

  • Numbered steps with copy-paste commands
  • Verification check after EVERY step
  • Time estimates for capacity planning
  • Rollback procedure for every destructive action
  • Escalation paths with decision criteria

4. Maintenance

  • Staleness detection linked to config file modification dates
  • Quarterly review cadence
  • Staging dry-run validation framework

When to Use

  • Codebase has no runbooks and you need to bootstrap them
  • Existing runbooks are outdated or incomplete
  • Onboarding a new engineer for on-call rotation
  • Preparing for an incident response drill
  • Post-incident improvement: updating runbooks with lessons learned

Stack Detection

Scan the repository before writing any runbook:

# CI/CD Platform
[ -d ".github/workflows" ] && echo "GitHub Actions"
[ -f ".gitlab-ci.yml" ]    && echo "GitLab CI"
[ -f "Jenkinsfile" ]       && echo "Jenkins"

# Database
grep -rl "postgres\|postgresql" package.json pyproject.toml 2>/dev/null && echo "PostgreSQL"
grep -rl "mysql\|mariadb" package.json 2>/dev/null && echo "MySQL"
grep -rl "mongodb\|mongoose" package.json 2>/dev/null && echo "MongoDB"

# Hosting
[ -f "vercel.json" ]       && echo "Vercel"
[ -f "fly.toml" ]          && echo "Fly.io"
[ -f "railway.toml" ]      && echo "Railway"
[ -d "terraform" ]         && echo "Terraform (custom cloud)"
[ -d "k8s" ] || [ -d "kubernetes" ] && echo "Kubernetes"
[ -f "docker-compose.yml" ] && echo "Docker Compose"

# Framework
[ -f "next.config.mjs" ] || [ -f "next.config.ts" ] && echo "Next.js"
grep -q "fastapi" requirements.txt 2>/dev/null && echo "FastAPI"
[ -f "go.mod" ] && echo "Go"

Deployment Runbook Template

# Deployment Runbook — [App Name]

**Stack:** [Framework] + [Database] + [Hosting]
**Last verified:** YYYY-MM-DD
**Owner:** [Team Name]
**Estimated total time:** 15-25 minutes

---

## Staleness Check

| Config File | Last Modified | Affects Steps |
|-------------|--------------|---------------|
| vercel.json | `git log -1 --format=%ci -- vercel.json` | Deploy, Rollback |
| db/schema.ts | `git log -1 --format=%ci -- db/schema.ts` | Migration |
| .github/workflows/deploy.yml | `git log -1 --format=%ci -- .github/workflows/deploy.yml` | CI |

If any config was modified after "Last verified" date, review affected steps.

---

## Pre-Deployment Checklist
- [ ] All PRs merged to main
- [ ] CI passing on main branch
- [ ] Database migrations tested in staging
- [ ] Rollback plan confirmed
- [ ] On-call engineer notified

## Step 1: Verify CI Status (2 min)

```bash
# Check latest CI run
gh run list --branch main --limit 3

# Verify specific run
gh run view <run-id>

VERIFY: Latest run shows green checkmark. If red, do not proceed.

Step 2: Apply Database Migrations (5 min)

# Staging first
DATABASE_URL=$STAGING_DB_URL pnpm db:migrate

# Verify migration applied
DATABASE_URL=$STAGING_DB_URL pnpm db:migrate status

VERIFY: Output shows "All migrations applied" with today's date.

# Production (only after staging verification)
DATABASE_URL=$PROD_DB_URL pnpm db:migrate

VERIFY: Same output as staging. If error, see Rollback section.

WARNING: For migrations on tables with >1M rows, schedule during low-traffic window and monitor lock wait times.

Step 3: Deploy to Production (5 min)

# Option A: Git push triggers deployment
git push origin main

# Option B: Manual trigger
vercel --prod
# or: fly deploy
# or: kubectl apply -f k8s/deployment.yaml

VERIFY: Deployment dashboard shows new version in progress. Note the deployment URL/ID for rollback.

Step 4: Smoke Test (5 min)

# Health check
curl -sf https://myapp.com/api/health | jq .

# Critical user path
curl -sf https://myapp.com/api/v1/me \
  -H "Authorization: Bearer $TEST_TOKEN" | jq '.id'

# Check error rate (wait 2 minutes for data)
# Dashboard: [link to monitoring dashboard]

VERIFY:

  • Health returns {"status": "ok", "db": "connected"}
  • User endpoint returns a valid user ID
  • Error rate < 1% on monitoring dashboard

Step 5: Monitor (10 min)

Watch these metrics for 10 minutes after deployment:

  • Error rate: < 1% (dashboard: [link])
  • P95 latency: < 200ms (dashboard: [link])
  • Active DB connections: < 80% of max (query below)
psql $PROD_DB_URL -c "SELECT count(*) FROM pg_stat_activity;"

VERIFY: All metrics within normal range. If any spike, proceed to Rollback.

Rollback

If smoke tests fail or metrics degrade:

# Instant rollback via Vercel
vercel rollback [previous-deployment-url]

# or Fly.io
fly releases --app myapp
fly deploy --image [previous-image]

# or Kubernetes
kubectl rollout undo deployment/myapp

# Database rollback (ONLY if migration was applied in this deploy)
DATABASE_URL=$PROD_DB_URL pnpm db:rollback

VERIFY: Previous version serving traffic. Run smoke tests again.

Escalation

Level Who When Contact
L1 On-call engineer First responder PagerDuty rotation
L2 Platform lead DB issues, rollback failures Slack: @platform-lead
L3 VP Engineering Production down > 30 min Phone: [number] 

## Incident Response Runbook Template

```markdown
# Incident Response Runbook

**Severity:** P1 (down), P2 (degraded), P3 (minor)
**Estimated time:** P1: 30-60 min, P2: 1-4 hours, P3: next business day

---

## Phase 1: Triage (5 min)

### Confirm the Incident

```bash
# Is the app responding?
curl -sw "%{http_code}" https://myapp.com/api/health -o /dev/null

# Check for errors in recent logs
vercel logs --since=15m | grep -i "error\|exception\|5[0-9][0-9]"
# or: kubectl logs -l app=myapp --since=15m | grep -i error

VERIFY: 200 = app is up. 5xx or timeout = incident confirmed.

Declare Severity

Condition Severity Action
Site completely unreachable P1 Page L2/L3 immediately
Partial degradation or slow P2 Notify team channel
Single feature broken P3 Create ticket, fix in business hours

Communicate

# Post to incident channel (adjust for your tool)
Slack: #incidents
"INCIDENT: [severity] — [brief description]. Investigating. Updates every 15 min."

Phase 2: Diagnose (10-15 min)

Check Recent Changes

# Was something just deployed?
vercel ls --limit 5
# or: kubectl rollout history deployment/myapp

# Recent commits
git log --oneline -10

Check Database

# Active queries (look for long-running or blocked queries)
psql $PROD_DB_URL -c "
SELECT pid, now() - query_start AS duration, state, query
FROM pg_stat_activity
WHERE state != 'idle'
ORDER BY duration DESC
LIMIT 20;"

# Connection pool saturation
psql $PROD_DB_URL -c "
SELECT count(*) AS active,
       (SELECT setting::int FROM pg_settings WHERE name = 'max_connections') AS max
FROM pg_stat_activity;"

Diagnostic Decision Tree

Recent deploy + new errors → ROLLBACK (see Deployment Runbook)
DB queries hanging        → Kill long queries, check connection pool
External API failing      → Check status pages, enable circuit breaker
Memory/CPU spike          → Check for infinite loops, scale up temporarily

Phase 3: Mitigate (variable)

# Kill a runaway database query
psql $PROD_DB_URL -c "SELECT pg_terminate_backend(<pid>);"

# Rollback last deployment
vercel rollback [previous-url]

# Scale up (if capacity issue)
fly scale count 4 --app myapp
# or: kubectl scale deployment/myapp --replicas=4

Phase 4: Resolve and Postmortem

Within 24 hours of resolution:

  1. Write incident timeline (what happened, when, who noticed, what fixed it)
  2. Identify root cause (5 Whys analysis)
  3. Define action items with owners and due dates
  4. Update this runbook if a step was missing or wrong
  5. Add monitoring/alerting that would have caught this earlier

## Database Maintenance Runbook Template

```markdown
# Database Maintenance — PostgreSQL

**Schedule:** Weekly vacuum (automated), monthly manual review

## Backup

```bash
pg_dump $PROD_DB_URL \
  --format=custom \
  --compress=9 \
  --file="backup-$(date +%Y%m%d-%H%M%S).dump"

VERIFY: File exists and size > 0. Test monthly with:

pg_restore --dbname=$STAGING_DB_URL backup-*.dump
psql $STAGING_DB_URL -c "SELECT count(*) FROM users;"

Vacuum and Reindex

# Check bloat
psql $PROD_DB_URL -c "
SELECT tablename,
       pg_size_pretty(pg_total_relation_size(schemaname||'.'||tablename)) AS size,
       n_dead_tup,
       ROUND(n_dead_tup::numeric / NULLIF(n_live_tup, 0) * 100, 1) AS dead_pct
FROM pg_stat_user_tables
ORDER BY n_dead_tup DESC
LIMIT 10;"

# Vacuum high-bloat tables (non-blocking)
psql $PROD_DB_URL -c "VACUUM ANALYZE tablename;"

# Reindex (CONCURRENTLY to avoid locks)
psql $PROD_DB_URL -c "REINDEX INDEX CONCURRENTLY index_name;"

VERIFY: dead_pct drops below 5% after vacuum.


## Staleness Detection Automation

```bash
#!/bin/bash
# check-runbook-staleness.sh
# Run weekly in CI to detect stale runbooks

RUNBOOK_DIR="docs/runbooks"
EXIT_CODE=0

for runbook in "$RUNBOOK_DIR"/*.md; do
  LAST_VERIFIED=$(grep -oP 'Last verified:\s*\K\d{4}-\d{2}-\d{2}' "$runbook" 2>/dev/null)
  if [ -z "$LAST_VERIFIED" ]; then
    echo "WARNING: $runbook has no 'Last verified' date"
    continue
  fi

  # Extract referenced config files
  CONFIG_FILES=$(grep -oP 'git log.*-- \K[^\x60]+' "$runbook" 2>/dev/null)
  for config in $CONFIG_FILES; do
    if [ -f "$config" ]; then
      LAST_MODIFIED=$(git log -1 --format=%ci -- "$config" | cut -d' ' -f1)
      if [[ "$LAST_MODIFIED" > "$LAST_VERIFIED" ]]; then
        echo "STALE: $runbook references $config (modified $LAST_MODIFIED, verified $LAST_VERIFIED)"
        EXIT_CODE=1
      fi
    fi
  done
done

exit $EXIT_CODE

Quarterly Review Process

Every quarter (add to team calendar):

  1. Run each command in staging — does it still work?
  2. Check config drift — compare config modification dates vs runbook verification date
  3. Test rollback procedures — actually roll back in staging
  4. Update contact info — L1/L2/L3 assignments may have changed
  5. Add new failure modes discovered in the past quarter
  6. Update "Last verified" date at the top of each reviewed runbook
  7. Archive obsolete runbooks — services get decommissioned

Common Pitfalls

Pitfall Fix
Commands with placeholder values Use environment variables: $PROD_DB_URL not postgres://user:pass@host/db
No expected output after commands Add VERIFY block with exact expected output
Missing rollback steps Every destructive step needs a corresponding undo
Runbooks that never get tested Schedule quarterly staging dry-runs
Outdated escalation contacts Review contacts every quarter
Migration runbook ignores table locks Explicitly call out lock risk for large table operations
Copy-pasting production URLs into runbooks Use environment variable references that resolve at runtime

Best Practices

  1. Every command must be copy-pasteable — use env vars, not placeholder text
  2. VERIFY after every step — explicit expected output, not "it should work"
  3. Time estimates are mandatory — engineers need to know if they have time before SLA breach
  4. Rollback before you deploy — plan the undo before executing the action
  5. Runbooks live in the repo — docs/runbooks/, versioned with the code they describe
  6. Postmortem drives runbook updates — every incident should improve at least one runbook
  7. Link, do not duplicate — reference the canonical config, do not copy its contents
  8. Test runbooks like you test code — untested runbooks are worse than no runbooks (false confidence)

Troubleshooting

Problem Cause Solution
Stack detection returns no results Repo uses non-standard config file names or paths Manually specify the stack in the runbook header; extend detection script with custom paths
Generated commands fail in staging Environment variables not set or differ between environments Verify all referenced env vars exist in the target environment with printenv | grep PROD before executing
Staleness script reports false positives Config files touched by formatting-only commits (linting, whitespace) Filter staleness checks by diffing actual content changes: git diff --stat on the flagged commit
Runbook steps are out of order after a platform upgrade Hosting provider changed their deploy pipeline or CLI flags Re-run stack detection after every major platform upgrade; diff the new CLI help output against runbook commands
Escalation contacts are stale Team rotations or org changes not reflected in runbooks Integrate escalation tables with your on-call tool API (PagerDuty, Opsgenie) so contacts resolve dynamically
Rollback procedure fails mid-execution Database migration was partially applied before the deploy failed Always wrap migrations in transactions where the engine supports it; include a "partial rollback" section for non-transactional DDL
Runbook verification checks pass but the feature is broken Smoke tests only cover health endpoint, not critical user paths Add at least three smoke-test URLs per runbook: health, auth, and one core business endpoint

Success Criteria

  • Runbook coverage >= 90% — every production service has at least a deployment and incident response runbook
  • Mean time to mitigate (MTTM) drops by 30%+ within one quarter of adopting generated runbooks
  • Zero placeholder commands — every command in every runbook is copy-pasteable without manual editing beyond env var substitution
  • Staleness rate < 10% — fewer than 10% of runbooks flagged as stale in any given quarterly review cycle
  • Quarterly dry-run pass rate >= 95% — at least 95% of runbook steps execute successfully in staging during scheduled dry-runs
  • On-call onboarding time < 2 hours — a new engineer can read all runbooks for their service and feel confident to handle L1 incidents within two hours
  • Post-incident runbook update rate = 100% — every postmortem produces at least one runbook addition or correction

Scope & Limitations

This skill covers:

  • Generating deployment, incident response, database maintenance, scaling, and monitoring runbooks from codebase analysis
  • Stack detection for common CI/CD platforms (GitHub Actions, GitLab CI, Jenkins), databases (PostgreSQL, MySQL, MongoDB), and hosting providers (Vercel, Fly.io, Kubernetes, AWS)
  • Staleness detection automation and quarterly review processes
  • Escalation path templates with severity-based routing

This skill does NOT cover:

  • Automated execution of runbook steps — it generates documentation, not orchestration (see ci-cd-pipeline-builder for automated pipelines)
  • Infrastructure provisioning or Terraform/Pulumi code generation (see migration-architect for schema migration tooling)
  • Observability stack setup such as Prometheus rules, Grafana dashboards, or alert definitions (see observability-designer for monitoring infrastructure)
  • Security incident response or vulnerability remediation playbooks (see skill-security-auditor for security-focused analysis)

Integration Points
