Git Commit with AI Co-author
Every commit that contains AI-assisted changes should credit the AI agent as a
co-author using the GitHub co-author trailer convention.
Co-author identity
Use your own agent identity for the trailer. Known identities:
| Agent | Trailer |
|---|
| Bob (IBM) | Co-authored-by: Bob <bob@ibm.com> |
| Claude (Anthropic) | Co-authored-by: Claude <claude@anthropic.com> |
| GPT-4 (OpenAI) | Co-authored-by: GPT-4 <gpt4@openai.com> |
| Gemini (Google) | Co-authored-by: Gemini <gemini@google.com> |
If your identity is not listed, use Co-authored-by: <AgentName> <agentname@provider.com>.
Commit message format
The trailer must be separated from the subject/body by a blank line:
<subject line>
<optional body paragraphs>
Co-authored-by: <AgentName> <identity@provider.com>
Steps
-
Stage the relevant files:
git add <files>
# or: git add .
-
Commit with the co-author trailer. Use -m twice — first for the subject,
second for the trailer (git appends them with a blank line between):
git commit -m "<subject>" -m "Co-authored-by: <AgentName> <identity@provider.com>"
If a longer body is also needed:
git commit -m "<subject>" -m "<body paragraph>" -m "Co-authored-by: <AgentName> <identity@provider.com>"
-
Verify the trailer was recorded:
git log -1 --format="%B"
