Use when driving Google's Antigravity CLI (`agy`) non-interactively / headlessly — `agy -p`/`--print`, running Antigravity from a script or another agent, capturing its answer, or automating a Gemini-backed agent call from the terminal. Triggers include "call/run agy from the command line", "antigravity headless / non-interactive", "agy -p", "is there an antigravity exec/print mode", "automate antigravity", "have Claude/the agent run agy", "agy prints nothing / empty output / no stdout", "drive Antigravity CLI from a script", "use agy/Gemini as a cross-vendor consultant or reviewer over files", "pick the agy model". Covers install + the keyring auth shared with the IDE, the **empty-stdout-under-pipe** footgun and the transcript-recovery workaround, the 5-minute print timeout, permission/sandbox safety (including the **cwd-escape** footgun when letting agy read files itself), model selection (`--model`), the tool-free file-reading **consultant pattern**, and troubleshooting. Do NOT use for the interactive `agy` TUI, the Antigravity IDE (Electron app), Antigravity 2.0 desktop, the Antigravity SDK (Python), or the hosted Gemini API (that's the gemini-api skill).

From the source SKILL.md

Drive Google's Antigravity CLI from a script or another agent: fire a prompt at a Gemini-backed agent and recover the answer. agy -p "..." (aka --print / --prompt) is the non-interactive entry point — it runs one prompt to completion and exits, no TUI.

What this skill does

Antigravity CLI is a community-contributed Claude Code skill in the content-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/antigravity-cli/ and loads when your prompt matches the skill's trigger.
