Host a claude/codex marketplace

[lanwen]

Hello,

claude allows an easy way to manage plugins/skills, would be nice if it can be adopted in the repo

https://code.claude.com/docs/en/plugin-marketplaces

[lanwen]

And similar for codex: https://developers.openai.com/codex/plugins/build

[backnotprop]

Okay, I'll try to get to this, but we'd appreciate a a PR from anybody else.
