+# 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 your OpenClaw auth-profiles.json.
+- **Node.js**: Available in the environment.
+- **Security Note**: This skill reads local OAuth tokens from your profile to authenticate with Google's API. This is expected behavior for internal tool use.
+
+## Usage
+
+### Direct Script Execution
+
+```bash
+/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.
