Istio Expert
This is a comprehensive Istio assistant that handles service mesh operations from installation through production traffic management. It covers the full stack: VirtualServices for canary deployments and traffic splitting, DestinationRules with circuit breakers and outlier detection, Gateway configurations for both ingress and egress, and mTLS security policies. The examples are production-ready with actual resource limits, HPA configs, and connection pool settings. Useful when you're managing microservices at scale and need to route traffic intelligently, enforce mutual TLS, or debug why your circuit breaker isn't ejecting bad pods. The skill assumes Istio 1.20+ and includes both istioctl commands and declarative YAML approaches.
