01Result
OpenZeppelin/openzeppelin-contracts ↗OpenZeppelin/openzeppelin-contracts AI coding statistics: 15%
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. Across the whole index, 96% of agent commits are assisted.
Agent share by month

Peak month: 33.3%. 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 | 155 |
| Merge commits removed | −0 |
| CI / dependency bots removed | −28 |
| Considered | 127 |
Bots are excluded from the denominator entirely. Agent attribution requires a literal supported signature; no code-style inference is used.

06Peer context
Position among comparable repositories
The cohort uses the same release and measurement window, then narrows to the repository’s ecosystem and removes low-activity observations.
Only 1 eligible repositories remain; qmmit requires at least 10 before showing a percentile. The cohort definition and sample size remain visible so the omission is auditable.

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