Antigravity Image Generation

Generate high-quality images using the internal Google Antigravity API (Gemini 3 Pro Image). This skill bypasses the need for browser automation by using the daily-cloudcode-pa.sandbox endpoint directly with your OAuth credentials.

Prerequisites

Google Antigravity OAuth Profile: Must be present in ~/.clawdbot/agents/main/agent/auth-profiles.json.
Node.js: Available in the environment.

Usage

Direct Script Execution


/home/ubuntu/clawd/skills/antigravity-image-gen/scripts/generate.js \

  --prompt "A futuristic city on Mars" \

  --output "/tmp/mars.png" \

  --aspect-ratio "16:9"

Arguments

--prompt (Required): The description of the image.
--output (Optional): Path to save the image (default: /tmp/antigravity_<ts>.png).
--aspect-ratio (Optional): 1:1 (default), 16:9, 9:16, 4:3, 3:4.

Output

The script writes the image to the specified path.
It prints MEDIA: <path> to stdout, which allows Clawdbot to automatically detect and display the image.

Troubleshooting

429 Resource Exhausted: Quota limit reached. Wait or check your project limits.
No image data found: The model might have refused the prompt (safety) or the API structure changed. Check the "Model message" output.
Auth Error: Ensure you have logged in via google-antigravity provider.
