What shapes this result

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

Assisted or autonomous

597assisted
84autonomous

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 window1,476
Merge commits removed−157
CI / dependency bots removed−0
Considered1,319

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.
