02Drivers

What shapes this result

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

Assisted or autonomous

16assisted

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.

Agent share by month

Peak month: 25.8%. Bars are scaled to that peak, not to 100%.

Agent	Vendor	Commits	Share
Claude Code	Anthropic	10	5.4%
GitHub Copilot	GitHub	4	2.2%
Cursor Agent	Anysphere	3	1.6%

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	396
Merge commits removed	−0
CI / dependency bots removed	−212
Considered	184

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

Run the same detector locally.

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