Yes, I agree. I’m about to drop Claude Code because it’s become literally unusable.

Today, Opus went in circles trying to get a toggle button to work.

Same. Asked CC Opus about a change in a particular file...it looked in a totally different file and told me there was no change.

I've switched to max thinking mode as my default and that's helping in some capacity.

It's not necessarily back to where it was, but it's not desk-flipping bad.
