Small macOS tool for keeping SKILL.md copies in sync across agents — feedback welcome

[yangl326-Dylan]

Hi everyone,

I use skills in Claude Code, Codex, Gemini CLI and OpenCode, and kept running into the same problem: the same skill ends up in 5–7 directories, and I have no idea which copy is current until something breaks.

So I built AgentKeeper — a small native macOS app plus an ak CLI. It scans the skill directories each agent actually reads, shows them in one catalog, flags same-named copies whose contents have drifted, and lets you disable/restore a skill safely (it snapshots before every change and can roll back).

A few things I deliberately kept conservative:

• read-only by default — it doesn't touch files until you ask
• no background daemons, no auto-sync
• MIT, core features free

It's very early and macOS 15+ only for now. I'm not trying to sell anything — I'd genuinely like feedback from people who maintain skills, especially on the hard part: how do you decide which copy is the source of truth, and how should plugin-managed copies (like npm caches) be handled?

If you have a minute, I'd love to hear how you organize skills across agents. And if you try it, issues and ideas are very welcome — happy to improve it together.
