Why One Developer Leaves AI Co-Author Tags in Commits

Transparent AI Collaboration in Git Commits

A developer on r/ClaudeAI explains their practice of intentionally including Co-Authored-by: Claude in Git commit messages. They've observed this decision often provokes more discussion than the actual code changes themselves.

The EXIF Data Analogy

The developer compares AI co-author tags to EXIF metadata in photography: "A photograph taken on a Canon Rebel XTi doesn't become a worse photograph (or best) because you can see the metadata. A Canon in my hands obviously won't produce National Geographic covers. The tool, AI or not, is a provenance information."

They emphasize that the craft lies in the decisions: "framing, timing, what to keep, what to discard. The same applies to code."

How AI is Used for Surgical Changes

The developer describes using AI for specific types of work:

• Architectural changes
• Tightly scoped refactors (under 50 lines changed)
• As a "thinking partner to help me reason out loud or trace the root cause"

They clarify that "the tool didn't make the architectural decisions. I decided what to change and, just as importantly, what to leave alone."

The Challenge of Surgical AI Work

"Writing a tight, surgical patch with AI is genuinely harder than people assume," the developer notes. They compare it to "parking a Ferrari in a tight spot: slowly, carefully, with full awareness of the surroundings."

Psychological and Social Dimensions

The developer references Sapolsky's work on how humans "categorically devalue things based on their origin rather than their quality as a threat response." They suggest the label "AI slop" functions similarly: "It lets you dismiss without evaluating. The amygdala gets to skip the prefrontal cortex."

Their motivation for transparency: "I'd rather have an honest conversation about how we evaluate work than quietly benefit from people's inability to tell the difference."

The post concludes by asking whether others leave the co-author tag, strip it, or have found it changes how their contributions are received.
