19.7%

of 66 commits 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.

A small group is using agents. Adoption has spread beyond one person but is not project-wide.

Assisted — a developer’s identity authored the commit and the agent added itself as co-author. The agent ran git commit during a working session, with a person there. Autonomous — a bot identity is the author, no human in the loop. Across the whole index, 93.7% of agent commits are assisted.

What was excluded

Commits in window	67
Merge commits removed	−0
CI / dependency bots removed	−1
Considered	66

Bots are excluded from the denominator entirely. Counting dependabot as “AI-written code” is the fastest way to produce a meaningless number.

How this was measured

Measured over February–August 2026, cloned directly. Detection is deterministic string matching against signatures agents write about themselves — no heuristics, no style analysis. Merge commits and CI bots are excluded from the denominator. The figure is a floor: squash merges strip trailers, so real usage is higher. Contributor counts are aggregate — no individual is named.
