How this was measured
2% of merged commits carry agent attribution — a floor, not the share; tools that only complete code inline leave no commit trail, so the unattributed side includes AI-assisted work; 5 PRs came off an agent branch with no commit attribution, so the real share runs higher; reads 100 of 35988 merged PRs — the rest have not been analyzed yet.
Detected: OpenAI Codex, Claude Code, Cursor agent.
“Attributed” means a commit carried an agent’s signature — a co-author trailer, an agent commit identity, or an agent bot account. Tools that only complete code inline leave no such mark, so the other column is “rest”, not “human-written”. Full method and its limits
