Flaky Tests: Switch a Monitor's Action Type After Creation

Change a monitor’s action between Classify test status and Apply labels, or flip flaky and broken, without deleting and recreating it.

You can now change a Failure Rate or Failure Count monitor’s action after it’s created, instead of deleting and recreating the monitor. Switch between Classify test status and Apply labels, or flip a classification monitor between flaky and broken, and Trunk reconciles every active test against the new configuration right away.

Before this, the action you chose at creation was locked in — changing it meant deleting the monitor and starting over, which dropped the monitor’s existing state. Now you can iterate on a detection strategy in place. A common pattern: create a monitor with Apply labels to watch live test data without touching health status, confirm it activates on the right tests, then switch it to Classify test status once you trust the configuration.
