How to use agent skills in Copilot for Xcode?

[davidbjames]

I have installed an agent skill in my home folder ~/.agents and I would like to reference it in Copilot for Xcode. How do I do this? The skill shows up in Visual Studio Code (e.g. type /swiftui-expert-skill), but not in Copilot for Xcode.
