It really depends where the chips land, generally the overcurrent fault in the Jag has caught most of the problems I've seen with chips, and shut down the unit before damage was incurred. It is certainly possible though that the debris could cause a permanent failure, in fact I have one Jaguar on my desk I suspect may be a victim of such a failure

-If the motor is not installed on a robot, put it on a table and clamp it down.
-Use a circuit breaker inline with the power connection. All Circuit Breakers that attach to the PD Board are compatible with a standard female 12 AWG connector.
Can anyone else think of some ways to safely "hotwire" a motor?

The problem was you didn't specify any of these suggestions, you simply suggested 'hotwiring' the motor (the fact that you had to use quotes around the word would indicate you knew it was up for interpretation) and the most common, especially amongst rookie teams, interpretation I've seen for hotwiring is sticking the motor wires straight in to the battery side AMP connector, and similar things like that.
What you've described here (clamps, PD board, etc) is actually a very good idea I would recommend all teams try just to have experience testing motors that way, but I wouldn't ever consider this hotwiring, instead I'd call it a test rig, or something equally less scary sounding.
My post was not meant as an attack towards you, I just know students sometimes gloss over the rest of the content available to them once they think they have a workable solution and I was afraid a student may have seen your post and tried what I described and gotten hurt or damaged something before anyone could clarify what you meant.
