Given coding agent's demonstrated difficulties with concurrent code, even relatively simple concurrent code, it would be interesting to see how they do with temporal logic. I don't know enough to throw AI at the problems in that space but I wonder if they wouldn't crash and burn on it.

(I haven't had the opportunity to throw a current-gen frontier model at a concurrent problem because I haven't had one to try out lately. The best concurrency is no concurrency and the second-best concurrency is the "web request" model where many web requests are nominally running concurrently but they are otherwise fully isolated from each other and not trying to communicate at all. So maybe they're better, but I feel like if they were a lot better somebody would have noted that in a place I'd have seen by now.)
