This is very far from my experience. It's been impressive on a few things but as of now I'm on day 3 of trying to get it to fix an issue in an open source library I maintain that I haven't had time to deal with. I'm in an endless loop where it keeps having the same epiphany about the root cause, then it implements a "fix", then tries to verify via a test script, then when it runs into difficulty it keeps adding workarounds to the test script. I can't get it focused on the fact that it's acting on behalf of the library author and that hacking the test script has no value.

I am not disposed to AI skepticism. I'd love it if a tool existed that worked as this guy claims. Claude Code is the best tool of its type that I've worked with but I'd put it at "on balance a time-saver in a lot of cases, way more trouble than it's worth in many others".
