Google Antigravity Skills System

Google Antigravity’s skills system supports the same SKILL.md format as Claude Code and Codex, with both global (~/.gemini/config/skills/) and per-project (.agents/skills/) scopes.

Why a skill for this

Supporting the shared SKILL.md format means skills built for Antigravity aren’t locked to Google’s tooling — the same skill folder is portable to other compatible agents.

Good for

Antigravity users who want to install or author skills using Google’s own supported mechanism, or reuse skills built for other SKILL.md-compatible agents.
