Yes, but it's also true: OpenAI have said almost nothing in public about their support for skills (there's one tweet about the Codex CLI implementation https://x.com/thsottiaux/status/1995988758886580349 and that's it) while rolling out a pretty major feature - invented by their competitor - to their core 800m+ user product in the past 24 hours.

I think "quietly" is fair.

Fair point. Other boys cried wolf and made me scepitical.
