Rehearse a Change on Mirrored Traffic Before Switching

A new version can pass every test and still fail on the first real request, because the test never carried the shape of live input. This skill covers shadow traffic for agent runs: send a copy of live requests to the candidate version without letting its replies reach the user, compare both answers on the same input, ignore differences that are only formatting, and switch the live path only once the two agree on the traffic the candidate has actually seen.

Commands

$ openclaw agent add --name "Shadow Reviewer" --trigger "/shadow" --source "AWS Production" --message "Send a copy of each live request to the candidate version and record the reply for comparison. The candidate reply is never returned to the user."

$ openclaw alert-rule add --name "Shadow Divergence" --group-by "route" --window "15m" --action "Alert when the candidate and the live version return answers that differ beyond formatting for the same input."

$ openclaw auto-fix add --name "Hold the Switch" --condition "shadow.divergence_rate > 0.01" --action "Keep the live version serving and stop the switch until the divergence is understood." --approval "auto" --notify "#ops-info" --max-runs "10 per day" --cooldown "30m"

$ openclaw runbook add --name "Shadow Rehearsal" --trigger "/runbook shadow" --tags "development,rollout" --steps "Mirror live requests to the candidate. Record both replies. Compare them on the same input. Ignore formatting only differences. Switch the live path only after the two agree on real traffic."
