 description: "Docker, Kubernetes, and AWS ECS/Fargate patterns. Triggers on: Dockerfile, docker-compose, kubernetes, k8s, helm, pod, deployment, service, ingress, container, image, ecs, fargate, task definition, ecs service, awsvpc, FARGATE_SPOT, ALB, ecs vs kubernetes."
+when_to_use: "Use when running containers at scale — Dockerfile/compose authoring plus Kubernetes or ECS/Fargate orchestration — e.g. 'write a multi-stage Dockerfile', 'author a Helm chart or k8s Deployment+Service', 'set up an ECS Fargate task definition', 'ECS vs Kubernetes'. Reach for docker-ops for Docker-only build/compose work."
