- Monitoring and alerting (dashboards, alert rules, log aggregations)
- CI/CD pipelines and automation jobs
- Scheduled tasks and cron jobs
3. Data Management Checklist

- Complete decommission sign-off with stakeholders
- Archive this decommission documentation
Output Format
Create a markdown file named DECOMMISSION-${1:-[SERVICE_NAME]}.md with:
- Clear section headers
- Checkboxes for each action item
- Specific resource identifiers (not generic placeholders)
- Timeline and responsible parties for each major section
- Links to relevant documentation and tools
- Emergency rollback procedures
Important Notes
- This documentation should be created at deployment time when context is fresh
- Include actual resource identifiers, not examples
- Keep it updated as the service evolves
- Store it in the service repository for easy access
- Review and update quarterly or after major changes
