dair-ai/dair-academy-plugins ? reverse-engineered prompt

Build me a clean open source marketplace repo for Claude Code plugins, with a simple README that explains how to add the marketplace and install plugins from it.

I want the repo to include a set of ready to use plugins for things like image generation, lesson building, adaptive learning, multi model council style reasoning, survey paper generation, YouTube note taking, research wiki building, and an X based agent intelligence feed. Each plugin should have its own folder with the basic plugin metadata, a short setup guide, and clear usage examples so someone can install it and understand what it does right away.

Make the repo easy to browse, consistent, and friendly for contributors too. Include a clear structure for adding new plugins, and keep everything organized so the marketplace feels polished and trustworthy. If you need to, look up the current Claude Code plugin format online and follow the latest docs.
