What is counted

The author is an assistant's own account, such as the Copilot coding agent, Devin or Cursor's agent.
A 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.
An Assisted-by: or Generated-by: line names an assistant.
The message has the line an assistant leaves in it, such as “Generated with [Claude Code]” or the link to a Devin or Codex session.

Accounts and addresses are matched, not first names: a person called Claude, Devin or Jules is not an assistant.
