reverse engineering Gemini's SynthID detection
01Result
aloshdenny/reverse-SynthID ↗aloshdenny/reverse-SynthID AI coding statistics: 14.9%
One person is driving this. The headline number reflects a single contributor's workflow, not a project-wide shift.
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.
Agent share by month
| Month | Agent share | Considered commits |
|---|---|---|
| 2026-02 | 0% | 5 |
| 2026-03 | 0% | 11 |
| 2026-04 | 25.9% | 27 |
| 2026-07 | 0% | 4 |
Peak month: 25.9%. Bars are scaled to that peak, not to 100%.

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 | 58 |
| Merge commits removed | −11 |
| CI / dependency bots removed | −0 |
| Considered | 47 |
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.
