In my last project I wrote most stuff by hand but also used various Anthropic models, Gemini something and GLM 5.2. By line count the #1 was probably the IDE autocomplete though mostly for boring field initializations and the likes. The "hardest" part was some reverse engineering by GLM that Claude refused but that resultend in zero lines directly. So, how to attribute this?

Allowing tools to insert themselves into the git history only makes sense if you are purely vibecoding with a single model and don't even bother to check and clean it up anymore. Is this truly the default state of software development already? How the times have changed.
