01Result

Homebrew/homebrew-core ↗

Homebrew/homebrew-core AI coding statistics: 0%

of 94,467 commits in February–September 15, 2026 were committed by an AI agent — a floor, not an estimate

No signed agent commits found

No agent signatures were found in the last 94,467 considered commits. That is a real result, not a failure to measure.

It does not mean no AI was used here. A developer can use an agent and commit by hand without leaving a detectable git signature.

02Drivers

What shapes this result

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

No agent signatures were detected, so there are no agent, mode, or timing drivers to break down.

Which agents

Agent	Vendor	Commits	Share
Claude Code	Anthropic	23	0%
Cursor Agent	Anysphere	6	0%
OpenAI Codex	OpenAI	3	0%
GitHub Copilot	GitHub	1	0%

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	138,269
Merge commits removed	−43,733
CI / dependency bots removed	−69
Considered	94,467

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

Run the same detector locally.

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