Hold a Warm Pool So a Burst Skips Cold Start

The first task a worker handles after it is created waits for the worker to come up, load what it needs and reach a ready state, and that wait is paid again for every new worker. When work arrives in a burst, a pool that starts workers only after the work lands makes every task in the burst wait for the same slow step. This skill covers holding a small pool of warm workers so the first task is fast, keeping replacements coming before the warm set drops, and retiring warm workers that stay idle so the floor does not become a standing cost.

$ openclaw alert-rule add --name "Cold Start Wait" --group-by "worker" --window "10m" --action "Alert when the time from task arrival to first output is high because the worker had to start cold rather than come from the warm set."

$ openclaw auto-fix add --name "Top Up Warm Set" --condition "idle_workers < pool_floor" --action "Start workers up to the floor before the next burst, rather than starting them after the work has already arrived." --approval "auto" --notify "#ops-info" --cooldown "20m"

Pay the cold start before the burst, not during it

Hold a Warm Pool So a Burst Skips Cold Start

Every new worker spends time before its first task: it comes up, loads what it needs and reaches a ready state. If a pool starts workers only after work arrives, every task in a burst waits for that same slow step, and the burst feels far worse than the steady state. A warm pool pays that step ahea
