agent-badge - README badge for AI coding-agent usage
by•
"agent-badge" is an open-source CLI that adds a GitHub README badge showing aggregate AI coding-agent usage for a repo. It currently supports Claude Code and Codex, shows tokens plus an estimated cost, and publishes aggregate badge data only.

I built "agent-badge" because most conversations about AI-assisted development stay abstract. Repos are either silent about it or use a vague sentence that never gets updated. I wanted a small OSS tool that could make usage more concrete at the README level.
The constraint I cared about most was the boundary between useful and creepy.
So the tool is designed to publish aggregate badge data only. It does not publish prompts, transcripts, filenames, or local paths. Current support is Claude Code + Codex, and the cost shown is an estimate, not invoice-grade billing.
If you try it, the feedback I'd value most is around:
1. the attribution model
2. the privacy boundary
3. which sources / providers would matter next
Repo and install are in the listing. Happy to answer implementation questions all day.
