Are BuySkills skills compatible with Codex's sandbox?
Yes. BuySkills skills are packaged as portable prompt + tool definitions that run inside Codex's sandbox the same way a local skill would. No special permissions are required beyond the ones the skill itself declares.
Does Trae's agent auto-discover BuySkills skills?
