Skill instructions
Antigravity Image Generation
Use the internal Google Antigravity sandbox to generate images with the gemini-3-pro-image model. This skill bypasses standard API restrictions by impersonating the VS Code plugin environment.
Usage
Generate an image from a prompt:
python3 {baseDir}/scripts/generate_image_antigravity.py --prompt "A futuristic cityscape with flying cars" --filename "city.png"
How it works
-
Authentication: Automatically retrieves OAuth tokens and Project ID from the local
auth-profiles.json. -
Impersonation: Uses the specific
antigravityUser-Agent and internal sandbox headers. -
Reliability: Includes automatic retry logic for
503 Service Unavailableerrors.
Parameters
-
--prompt/-p: Text description of the image to generate. -
--filename/-f: Path where the resulting PNG will be saved.
Notes
- The script prints a
MEDIA:path which OpenClaw uses to automatically upload the image to the chat channel. - Requires an active Antigravity session/login in the environment.
- See internal-api.md for technical details on the impersonated endpoint.

# Antigravity Image Generation
Use the internal Google Antigravity sandbox to generate images with the `gemini-3-pro-image` model. This skill bypasses standard API restrictions by impersonating the VS Code plugin environment.
## Usage
Generate an image from a prompt:
```bash
python3 {baseDir}/scripts/generate_image_antigravity.py --prompt "A futuristic cityscape with flying cars" --filename "city.png"
```
## How it works
1. **Authentication**: Automatically retrieves OAuth tokens and Project ID from the local `auth-profiles.json`.
2. **Impersonation**: Uses the specific `antigravity` User-Agent and internal sandbox headers.
3. **Reliability**: Includes automatic retry logic for `503 Service Unavailable` errors.
## Parameters
- `--prompt` / `-p`: Text description of the image to generate.
- `--filename` / `-f`: Path where the resulting PNG will be saved.
## Notes
- The script prints a `MEDIA:` path which OpenClaw uses to automatically upload the image to the chat channel.
- Requires an active Antigravity session/login in the environment.
- See [internal-api.md]({baseDir}/references/internal-api.md) for technical details on the impersonated endpoint.Related skills
