This is a very good question.

**Background**

At Alibaba Cloud, our development team uses a variety of AI coding tools,
including Cursor, Claude Code, Gemini-CLI, Lingma, and Qoder, etc. To
measure adoption—specifically, how many developers are using AI coding
tools and how much code is AI-generated—we needed a unified tracking
mechanism compatible with all these tools. I chose to implement a git
commit-msg hook that automatically detects the AI coding tool responsible
for a commit based on environment variables at commit time.

**Why choose the Co-developed-by trailer for AI developer?**

Git repositories already use the Co-authored-by trailer to credit human
collaborators. Since any human developer, including co-authors, may use
AI coding tools to assist their work, introducing a distinct trailer
like Co-developed-by allows us to clearly differentiate between human
contributors and the AI tools they used. For example, the following
commit trailers indicate two human engineers and the respective AI
coding tools they employed:

    Co-developed-by: Cursor <noreply@cursor.com>
    Co-authored-by: Real Person <real.person@example.com>
    Co-developed-by: Gemini <noreply@developers.google.com>
    Signed-off-by: Me <me@example.com>

I noticed that Sasha Levin (NVIDIA) previously proposed adopting
the Co-developed-by trailer for the Linux kernel as well.
