Someone posted a theory on reddit that /ultrareview might use Mythos. Seems at least plausible. It runs in the cloud like /ultraplan, and is gated by the CC - so no way to inspect what it's doing, or give it "dangerous" tasks, right?

I just ran it against an auth-related PR, and it found great edge-case stuff. Very interesting! I get the feeling we will be here a lot more about /ultrareview.
