less/less.js AI coding statistics: 13.6%

of 66 commits in February–September 15, 2026 were committed by an AI agent — a floor, not an estimate

Too little recent activity to publish. Only 66 commits landed in this window, so the percentage is noisy. Repositories below 100 are excluded from the index for this reason.

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

9assisted

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.

Agent share by month

Peak month: 15.8%. Bars are scaled to that peak, not to 100%.

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 window	80
Merge commits removed	−5
CI / dependency bots removed	−9
Considered	66

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

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.

CohortJS/TS · 376 eligible repositories · at least 100 considered commits2026-09-18-v3.0 · February–September 15, 2026 · 194 of 570 ecosystem repositories excluded

Comparison withheld for low activity

This observation does not meet the 100-commit publication threshold. 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.
