facelessinfluential/antigravity-awesome-skills-gemini ? reverse-engineered prompt

Build me a GitHub project that works like an installable library of reusable AI coding skills.

I want a repo where people can browse a big catalog of skill playbooks, install them with a simple command, and then use them in tools like Claude Code, Cursor, Gemini CLI, Codex CLI, and Antigravity. It should include a clean README, a searchable skills catalog, some curated bundles, and a few workflow guides for common tasks like planning, coding, debugging, testing, and security review.

Please make the install experience feel easy for non experts, with a command that can place the skills in the right folder automatically, plus a way to install for different tools if needed. I also want the project organized so it can support official and community skill collections, plugin friendly distribution, and clear docs for getting started fast.

If you need to look up current docs or command details online, go ahead and do that.
