Operations 1

Each operation below carries the questions people ask an LLM about it and the instructions they give an agent to run it. Generated by API Evangelist overlay

GET /metrics Get agent and job counts for a cluster · Get Cluster Agent Metrics #

Ask an LLM

“How many jobs are waiting and how many agents are idle in my cluster?”

“Can an autoscaler read current agent and job counts using an agent token?”

Tell an agent

Get the current agent and job metrics for my cluster.

Check queued job counts so I can size the agent pool.
