I tend to take one or two approaches. First being “Slowest and Loudest” in that the one worst at the test makes the roll, most of the time with help. Possibly also backed by a setup action.

Second is turning it into an extended test, I’ll put up a tracker and we’ll see what actions the narrative drags up. With this option a failure is only Stealth Over if it has to be, when there is no other reasonable consequence. So clanker can clank.
