Adoption is broad. Many contributors are committing agent-authored work, which is what a real organisational rollout looks like.

02Drivers

What shapes this result

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

Assisted or autonomous

71assisted
0autonomous

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.

Public commit samples let you inspect the signatures behind the aggregate result.

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 window3,619
Merge commits removed−1,095
CI / dependency bots removed−378
Considered2,146

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

05Provenance

Pinned to a source state

This observation names the repository state, release, and detector that produced it. Use these identifiers when reproducing or citing the result.

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.

CohortZig · 3 eligible repositories · at least 100 considered commits2026-09-18-v3.0 · February–September 15, 2026 · 0 of 3 ecosystem repositories excluded
Comparison withheld for a small cohort

Only 3 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.

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