It seems to be great at writing tests, spitting out UI code, and many other things where there are many examples around.
Among other things I work on database optimizers and there Claude fails spectacularly. It produces wrong code, fails to find the right places where to hook up an abstraction, overlooks affects on other parts of the code, and generally confidently proposes changes that simply do not work at all (to put it mildly).
Your mileage may vary... It seems to be depend heavily on the amount of existing (open) code around.
