It's not a terrible idea, but I'm not sure how that would work logistically.

When I use Codex to do vibe coding stuff, I don't usually have one big prompt, I usually have it do small things piecemeal and I iterate with it later. Maybe I'm using it wrong but it tends to be more "conversational" and I think that would be harder to share, especially considering I'll do things over dozens of sessions.

I suppose I could keep an archive of every session I've ever opened with Codex and share that, but thus far I haven't really done that.

Granted, I don't really share my stuff with "Show HN".
