Docs: add guidance for building an agent-agnostic plugin marketplace

[neeltom92]

Also opened as #41; cross-posting since CONTRIBUTING.md routes proposals here.

Ask

Add a page to agent-plugins.org documenting how to create an agent-agnostic marketplace — one repo holding multiple plugins, installable from more than one client.

A client-neutral equivalent of Claude Code's Plugin marketplaces page.

Why

Most orgs package their plugins together in a single repo, so this is the common case rather than an edge case. But the spec and the guides cover how to build one plugin, then stop. Nothing covers shipping a repo of plugins to more than one client — which is the point of a portable format.

Claude Code documents how to build a marketplace. Cursor documents its own. [agent-plugins.org], but (https://agent-plugins.org/) documents neither.

I think marketplaces are a distribution artifact, and I think distribution is outside the scope of the Agent Plugins spec.

For something like that, my personal recommendation is AI Catalog (or ARD, which is built on top of AI Catalog).
