Awesome Antigravity Skills

What are Agent Skills?

Skills are an open standard for extending agent capabilities: a skill is a folder containing a SKILL.md file with instructions the agent follows when working on specific tasks. Antigravity discovers workspace skills in .agents/skills/ and global skills in ~/.gemini/config/skills/. Because the format is shared with Claude Code, Cursor, Codex CLI, and Gemini CLI, the ecosystems are largely interoperable — most entries below originate in the Claude Code ecosystem and work in Antigravity as-is.
