Agreed, this site isn't reflective of any of my experience with Claude. It does what I ask it to do, and when it doesn't get it right, it generally turns out there's a good reason for it, which is any of the 100 reasons a human doesn't always get code fixes right on the first try either.
I do remember that one of the first things I did with my CLAUDE.md was to tell it to stick to the scope of the task, never to jump ahead and do extra "helpful" things without confirming with me first, and to follow best software practices including around refactoring but also to specifically avoid overengineering. I don't know if that is what's giving me a different experience from whatever the author seems to be "satirizing".
