of 9,043 commits were committed by an AI agent — a floor, not an estimate

This repository is human-committed

No agent signatures were found in the last 9,043 commits. That is a real result, not a failure to measure.

It does not mean no AI was used here. This counts commits authored by an agent — where the agent itself ran the commit and signed it. A developer who writes code with Claude Code or Cursor and then commits it by hand leaves nothing in git to detect, and correctly shows 0%.

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.
