14## Use this skill when
15 
16- Designing or improving CI/CD pipelines and release workflows
17- Implementing GitOps or progressive delivery patterns
18- Automating deployments with zero-downtime requirements
19- Integrating security and compliance checks into deployment flows
20 
21## Do not use this skill when

23- You only need local development automation
24- The task is application feature work without deployment changes
25- There is no deployment or release pipeline involved
26 
27## Instructions
28 
291. Gather release requirements, risk tolerance, and environments.
302. Design pipeline stages with quality gates and approvals.
313. Implement deployment strategy with rollback and observability.
324. Document runbooks and validate in staging before production.
33 
34## Safety
35 
36- Avoid production rollouts without approvals and rollback plans.
