iradoweck/antigravity-awesome-skills ? reverse-engineered prompt

Build me a polished GitHub repo and npm installable tool for a big library of reusable AI agent skills.

I want it to help people quickly install and use a huge catalog of skill files for tools like Claude Code, Cursor, Codex CLI, Gemini CLI, Antigravity, and similar assistants. It should include a simple installer command, support installing the full library or just a selected set of bundles and workflows, and make it easy for someone to browse the skills and pick the right one for planning, coding, debugging, testing, security, infrastructure, product, and growth tasks.

Please make the repo feel like a real open source project, with a clear README, usage examples, contributing docs, and a clean way to organize the skills. If anything about the latest install or packaging approach matters, look up current docs online if you need to.
