The share of each quarter’s commits that name an AI coding assistant: as their author, as a co-author, or in the line it signs with. A lower bound: an assistant that leaves no mark is not counted. Commits and active authors are those of the last 12 months; health is the project's pace of the last year.
Co-authored-by: line names an assistant, as Claude Code, Copilot, Cursor, Codex, Aider and others add when they commit for a person. A review bot whose suggestion was applied is named the same way.Assisted-by: or Generated-by: line names an assistant.Accounts and addresses are matched, not first names: a person called Claude, Devin or Jules is not an assistant.
