It would be trivial to create something like this but there are a few major problems with running such a platform that I think makes it not worth while for anyone (maybe some providers will try it, but it's still tough).

- you will be getting a TON of spam. Just look at all the MCP folks, and how they're spamming everywhere with their claude-vibed mcp implementation over something trivial.

- the security implications are enormous. You'd need a way to vet stuff, moderate, keep track of things and so on. This only compounds with more traffic, so it'd probably be untenable really fast.

- there's probably 0 money in this. So you'd have to put a lot of work in maintaining a platform that attracts a lot of abuse/spam/prompt kiddies, while getting nothing in return. This might make sense to do for some companies that can justify this cost, but at that point, you'd be wondering what's in it for them. And what control do they exert on moderation/curation, etc.

I think the best we'll get in this space is from "trusted" entities (i.e. recognised coders / personalities / etc), from companies themselves (having skills in repos for known frameworks might be a thing, like it is with agents.md), and maybe from the token providers themselves.

not ranked with comments but I’d expect solid quality from these and they should “just work” in Codex etc.

it feels like people keep attempting this idea, largely because its easy to build, but in practice people aren't interested using others' prompts because the cost to create a customized skill/gpt/prompt/whatever is near zero

I created a skill to write skills (based on the Anthropic docs). I think the value is really in making the skills work for your workflows and code base
