The agent works well in the demo. It calls the right APIs, does the right thing, and everyone is impressed. So the team gives it more access — a Kubernetes API here, a cloud provider credential there. It's fast to set up. It works.

It's the same problem we solved with service meshes — and then forgot we'd solved it. The Parallel That Should Make You Nervous Think back to how microservice architectures evolved before service meshes existed. Services called each other di
