I had a recent case where I, being the lead, sliced up the work real good into an epic and what not and a guy on the team just did a "hurr durr, Claude, go wild with all that" and threw a huge PR over the wall linked to 5+ stories.
Well, we got to have "the conversation" after that and learned how to fix these kinds of PRs together...
Claude absolutely loves to reimplement the wheel locally instead of just calling a method in a library we already depend on. Every doc comment and README.md update is bloated by 2-5x what's needed to communicate intent or to actually be read by a human later. It makes random drive-by edits that aren't necessary and weren't asked for in the prompt. It's a well oiled machine for producing astronomical bloat by default if you don't supervise and rein it in!
