MK-ORGANIZATION-1/AGENTS-COLLECTION ? reverse-engineered prompt

Build me a polished website and repo for an AI agent library that collects agent definitions, skills, prompts, workflows, hooks, plugins, and MCP configs across multiple coding assistants.

I want people to be able to browse everything in one place, search by platform or use case, and easily copy the right folder into their own tool setup. Make it feel like a serious production project, with a clean landing page, clear documentation, and simple install instructions for each platform. Add sections that explain what the collection is, how many agents and skills it includes, and how to use it with tools like Claude Code, Cursor, Copilot, Gemini, and the others mentioned in the README.

Also include security and CI friendly setup, since this repo talks about automated scans and deployment. If anything in the README is unclear, look up current docs online and make sensible choices.
