I don't know. Claude helped me implement a ton of features I had been procrastinating for months in a matter of days. I'm implementing features in my project faster than I can blog about them. It definitely manifested as a huge commit spike.

And it's not like I'm blindly commiting LLM output. I often write everything myself because I want to understand what I'm doing. Claude often comments that my version is better and cleaner. It's just that the tasks seemed so monumental I felt paralyzed and had difficulty even starting. Claude broke things down into manageable steps that were easy to do. Having a code review partner was also invaluable for a solo hobbyist like me.

My fav metric for codebase improvement (not feature improvement) is negative LOC. Nothing beats a patch that only deletes things without breaking anything or simply removing tests. Just dead code deletion.

Most effective engineers on the brownfield projects I've worked on, usually deleted more LOC than they've added, because they were always looking to simplify the code and replace it with useful (and often shorter) abstractions.
