npx claudepluginhub sickn33/antigravity-awesome-skills --plugin antigravity-bundle-aas-mobile-app-builderGuides observability patterns for Istio, Linkerd service meshes: metrics, traces, logs, golden signals, Prometheus/Grafana templates, PromQL queries for debugging latency, errors, SLOs.
Configures Istio, Linkerd, and Consul Connect for Kubernetes microservices. Generates mTLS, traffic routing, resilience policies, and observability configs.
Deploys and configures service meshes (Istio or Linkerd) for secure service-to-service communication, traffic management, and observability in Kubernetes clusters.
