SRE Discipline
Battle-tested SRE operational discipline for any infrastructure operation — deployments, rollbacks, migrations, cache invalidation, certificate management, DNS changes, firewall rules, container orchestration, and server maintenance. Use this skill whenever performing ANY operation that touches production systems, Docker containers, reverse proxies, SSL/TLS certificates, CDN caches, DNS records, firewall rules, load balancers, or deployment pipelines. Also use when debugging production incidents, planning infrastructure migrations, or reviewing infrastructure changes. If the task involves servers, containers, networking, or anything that could cause downtime — this skill applies. Even if you think the change is simple.
