Cross-Marketplace Loading

This marketplace demonstrates how to aggregate plugins from multiple sources without git submodules. External plugins use GitHub source references:

{
  "name": "vercel-react-best-practices",
  "source": {
    "source": "github",
    "repo": "vercel-labs/agent-skills",
    "path": "skills/react-best-practices"
  }
}

When users install these plugins, Claude Code fetches them directly from the source repository. This avoids the nested marketplace resolution issues associated with git submodules.
