A small group is using agents. Adoption has spread beyond one person but is not project-wide.
02Drivers
What shapes this result
Mode, timing, and detected signatures show whether the result reflects broad adoption or one concentrated workflow.
Assisted or autonomous
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 window | 418 |
| Merge commits removed | −77 |
| CI / dependency bots removed | −21 |
| Considered | 320 |
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.
