Nothing super-fancy. We have a common GitHub repo in our org for skills, and everyone checks out the repo into their preferred setup locally.

(To clarify, I meant that some engineers mostly use CC while others mostly use Codex, as opposed to engineers using both at the same time.)

Codex 5.2 automatically picked up my claude agents' skills. Didn't prompt for it, it just so happened that what I asked it for, one of claude's agents' prompts was useful, so Codex ran with it.
