Antigravity Claude Skills — Development skill for Claude Code

Antigravity Skills Manager

**Motivation**: A skill management system for the Gemini 3 framework that is interchangeable with the Claude skills frameworks and samples. It allows you to seamlessly ingest and use skills from the broader ecosystem as native Antigravity Workflows or Rules.

**Resources**:

• Antigravity Documentation
• Anthropics Skills Repo
• Gemini 3 Framework


This project provides a system to bootstrap **Antigravity Workflows** and **Rules** from external skill repositories.
