Draining In-Flight Work Before a Restart
Restarting an agent that is mid-task can leave a partially written record that is neither done nor cleanly retryable. This skill covers graceful drain: stop accepting new work, let in-flight tasks finish or reach a deadline, record anything that did not finish, replay it once after the restart, and route new work elsewhere while the drain runs.
Commands
$ openclaw runbook add --name "Graceful Agent Restart" --trigger "/runbook drain" --tags "operations,restart" --steps 'Step 1: Stop accepting new work. Step 2: Wait for in-flight tasks to finish or reach their deadline. Step 3: Record the tasks that did not finish. Step 4: Restart, then replay the recorded tasks once.'
$ openclaw command add --name "drain" --trigger "/drain" --source "AWS Production" --message "The operator wants to drain the worker before a restart. Stop intake, report the in-flight count, wait for it to reach zero or its deadline, then list anything still running."
$ openclaw cron add --name "Drain Window" --cron "0 3 * * *" --tz "UTC" --session isolated --message "Check for in-flight work and drain before the scheduled restart window."
$ openclaw alert-route add --name "Restart Window" --severity info --channel slack --to "#ops-info"

The task was writing when it died, so the record is half written and the retry cannot tell whether the work happened. A drain fixes this with four moves in a fixed orde
