1/
Kubernetes says everything looks healthy: Deployment 2/2 Ready, Service has endpoints, Ingress has an address.
But traffic still doesn’t arrive.
The problem is often not one broken object. It is the path between them.

5/
Example: the API-server relay returns 200.
That still does not prove real application traffic can reach the Service. A NetworkPolicy may treat that path differently.
Radar reports: “Reached via API server - not live traffic.”

The kubelet already restarts containers at 3am without asking anyone. Kubernetes is full of automation like that. AI agents add something different: judgment. Our CPO wrote a framework for deciding how much judgment to delegate.

Levels attach to verb-environment pairs, never to agents. "Restart pods in staging" and "delete PVCs in prod" can sit four levels apart under the same agent on the same cluster.

Radar is a portable Kubernetes interface that runs as a single binary from your laptop, offering topology, resource, and traffic visualization along with MCP support for AI agents.

a config change that never emitted a Kubernetes event, caught anyway

one minute: the crashloop still on the record, then the field diff showing what the value was before someone changed it

verdicts carry evidence and a confidence band. inconclusive is a real answer. an all-clear means it went and checked.

your deployment is 0/1 and kubectl logs gives you nothing.

correct. there is no pod. admission rejected it, and the reason is sitting in a controller status you have not opened.

it checks whether argo, flux or helm owns the resource first, and warns you your change is about to be reverted on the next reconcile.
