This repository is human-committed
No agent signatures were found in the last 18,889 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%.

What was excluded
| Commits in window | 18,889 |
| Merge commits removed | −0 |
| CI / dependency bots removed | −0 |
| Considered | 18,889 |
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.
