Does it support multi-namespace policies?

Yes, it generates standard Kubernetes manifests that can manage ingress and egress traffic across different namespaces using namespace selectors.

How does it help with security best practices?

It defaults to the principle of least privilege, helping users move away from permissive default-allow configurations toward zero-trust networking.

Is it compatible with specific CNI plugins?

It generates standard Kubernetes NetworkPolicy resources compatible with all common CNIs that support the spec, such as Calico, Cilium, and Antrea.

Can this skill modify existing Kubernetes policies?

Yes, it can analyze your current YAML configurations and generate updates to add ports, change labels, or refine access controls.
