Adoption is broad. Many contributors are committing agent-authored work, which is what a real organisational rollout looks like.

02Drivers

What shapes this result

Mode, timing, and detected signatures show whether the result reflects broad adoption or one concentrated workflow.

Assisted or autonomous

117assisted
1autonomous

Assisted — a developer’s identity authored the commit and the agent added itself as co-author. Autonomous — a bot identity authored the commit without a human identity attached.

04Method

What entered the denominator

The result begins with commit history, removes merges and routine automation, and reports literal agent signatures as a lower bound.

Exclusion ledger

Commits in window5,133
Merge commits removed−2,133
CI / dependency bots removed−368
Considered2,632

Bots are excluded from the denominator entirely. Agent attribution requires a literal supported signature; no code-style inference is used.

Deterministic signature matching; no code-style inference. Squash merges can remove trailers, so this result remains a measured floor.
