Antigravity CLI

Use this skill for Google Antigravity CLI, whose binary is agy. Do not call it antigravity in commands.

Default workflow

1. Determine whether the user needs non-interactive automation, interactive TUI help, configuration, artifact review, plugin work, or migration.
2. Prefer agy --print for scriptable one-shot tasks and agy / agy --prompt-interactive for live TUI workflows.
3. Check the local binary before giving command-specific guidance when possible:

   agy --help
   agy version
   

4. For risky work, keep sandboxing and permission prompts enabled. Do not suggest --dangerously-skip-permissions unless the user explicitly wants that risk and the workspace is trusted.
5. When changing settings, prefer the TUI /config, /permissions, /model, /keybindings, or /mcp commands. Edit JSON files directly only when the TUI path is unavailable or the user asks for file-level changes.

Gotchas

• --prompt is an alias for --print; it does not keep the session interactive.
• --model is supported on CLI for session model selection, and models can also be selected inside the TUI with /model or listed via agy models.
• agy --continue resumes the most recent conversation; use agy --conversation <id> for a specific session.
• Plugin management is under agy plugin ...; local Agent Skills live separately in skill paths.
• Artifact review is interactive; for headless automation, design prompts to ask for patch summaries or command output instead of relying on the review panel.
