Taken from the Co-Authored-By: Claude … trailer. Other tools don't name a model.

Repositories: every public, non-archived repository in the GTNewHorizons GitHub organisation (), including GTNH-maintained forks of upstream mods. Only each repository's default branch is read, so this counts work that was merged. A commit reachable from more than one repository counts once.
What counts as AI-assisted: a commit whose author, committer, or Co-authored-by / Assisted-by / Generated-by trailers name an AI tool (for example noreply@anthropic.com, copilot-swe-agent[bot], cursoragent@cursor.com), or whose message carries a tool's own footer, such as "Generated with Claude Code".
Tools looked for: . Tools with no matches don't appear in the charts.
What is not counted: prose mentions ("with ChatGPT's help", "bugs Claude found"), commits that only touch a CLAUDE.md file, AI use mentioned only in a pull request description, and any AI use nobody declared. These numbers are a floor, not an estimate of real usage.
Totals: the share is AI-assisted commits divided by all commits in the same slice. By default totals leave out automated commits (github-actions[bot], Dependabot, and other [bot] authors), which make up most of some repositories' history.
Overlap: a commit that credits two tools counts once in the totals, but appears under each tool in the per-tool charts.
