An analysis tool for Python that blurs the line between testing and type systems.
01Result
pschanely/CrossHair ↗pschanely/CrossHair AI coding statistics: 57.3%
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.
Agent share by month
| Month | Agent share | Considered commits |
|---|---|---|
| 2026-04 | 2.3% | 44 |
| 2026-05 | 44.8% | 29 |
| 2026-06 | 66.7% | 33 |

| 2026-09 | 100% | 10 |
Peak month: 100%. 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 | 215 |
| Merge commits removed | −0 |
| CI / dependency bots removed | −4 |
| Considered | 211 |
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.
