Cut a Tool Over Between Two Live Versions

A tool version is replaced while work is in flight, and a single deploy that stops the old version and starts the new one leaves a window with no working version and no way back. This skill covers the blue green shape for agent tools: bring the new version up beside the running one, warm it, move traffic across in one step, compare the two on the same signal, and keep the running version alive so that going back is another single step rather than a rebuild. The switch is only safe when both versions can serve at once and the cutover is one action, not a sequence of half steps.

Commands

$ openclaw command add --name "cutover" --trigger "/cutover" --source "Ops Console" --message "Move traffic from the running tool version to the new one in a single switch, and keep the running version up so a return is just another switch."

$ openclaw alert-rule add --name "New Version Worse" --group-by "tool_version" --window "15m" --action "Compare the error rate of the new version against the running version and alert when the new one is the worse of the two."

$ openclaw auto-fix add --name "Switch Back" --condition "new_version.error_rate > running_version.error_rate" --action "Send traffic back to the running version and stop the new version from taking new requests until it is inspected." --approval "auto" --notify "#ops-info" --cooldown "15m"

$ openclaw runbook add --name "Tool Cutover" --trigger "/runbook tool-cutover" --tags "development,ops" --steps "Start the new version beside the running one. Warm the new version with copied requests. Move traffic across in one step. Compare both versions on the same signal. Move back if the new version is worse. Retire the running version only after the new one holds."

Blue-Green Tool Cutover: One Switch Forward, One Switch Back

Cut a Tool Over Between Two Live Versions

# Blue-Green Tool Cutover for Agent Tools Replacing a live tool while work is in flight is risky if the deploy stops the old version before the new one can serve. A blue-green cutover keeps both versions running at once, so the switch is a single action and rolling back is just the reverse switch.
