In this example the task spun up by the opsmate operator was not functioning. we gave it a stab tried to diagnose the issue manually but couldn’t find a smoking gun.

Put my pride aside, I asked opsmate for help via opsmate chat --context k8s -m claude-3-7-sonnet-20250219 and gave it a vague hint. It narrowed down to the root cause, which is the serving pod being unhealthy.

It was very obvious in the hindsight ;) but we are very impressed by the well-balanced troubleshooting approach conducted by opsmate.
