Karpathy mentioned he hasn't written a line of code since December [0], says agents only actually started working around then. The trajectory in this report lines up with that pretty well: throughput was basically flat for most of 2025, picked up ~25% in Q4, then more than doubled in Q1 2026.
I've talked to people at a couple of companies that lean heavily on Claude Code internally, and fixing already-merged code still eats a big chunk of their week. Mostly because nobody's really tracking what's landing in the codebase anymore. So I went into this report expecting that pain to show up as a spike in "fixes." It kinda doesn't though? Fixes only went up 3pp (15→18%), while "growth" work picked up 7pp. So either the cleanup is happening earlier, in code review before merge, or commit data just can't see it. Curious if either of these matches what you're seeing.
