Not my experience at all. I’ve been using Claude Code on a large "hand written" project and it’s genuinely excellent at finding bugs and generating new methods or classes.

That said, it still frequently introduces subtle bugs, so I have to review every change carefully.

The real trick is learning when to use it. Some tasks are much faster to do myself, while others are faster with Claude Code.

Same experience here. It produces code that I would not accept if it was written by a human, but it also produces a lot of completely fine code. It made me clear tasks that I had been procrastinating for a long time.
