Description
Generate images using the internal Google Antigravity API (Gemini 3 Pro Image). High quality, native generation without browser automation.
README (SKILL.md)

Antigravity Image Generation\r
\r
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.\r
\r
Prerequisites\r
\r
- Google Antigravity OAuth Profile: Must be present in your OpenClaw auth-profiles.json.\r
- Node.js: Available in the environment.\r
- 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.\r \r
Usage\r
\r
Direct Script Execution\r
\r
/home/ubuntu/clawd/skills/antigravity-image-gen/scripts/generate.js \\r
--prompt "A futuristic city on Mars" \\r
--output "/tmp/mars.png" \\r
--aspect-ratio "16:9"\r
```\r
\r
### Arguments\r
\r
- `--prompt` (Required): The description of the image.\r
- `--output` (Optional): Path to save the image (default: `/tmp/antigravity_\x3Cts>.png`).\r
- `--aspect-ratio` (Optional): `1:1` (default), `16:9`, `9:16`, `4:3`, `3:4`.\r
\r
## Output\r
\r
- The script writes the image to the specified path.\r
- It prints `MEDIA: \x3Cpath>` to stdout, which allows Clawdbot to automatically detect and display the image.\r
\r
## Troubleshooting\r
\r
- **429 Resource Exhausted**: Quota limit reached. Wait or check your project limits.\r
- **No image data found**: The model might have refused the prompt (safety) or the API structure changed. Check the "Model message" output.\r
- **Auth Error**: Ensure you have logged in via `google-antigravity` provider.\r
Usage Guidance
Proceed cautiously. The SKILL.md says it will read your local Google OAuth profile and call an internal/sandbox Google endpoint, but the skill package contains no script code (the generate.js it references is missing) and the source is unknown. Before installing or using it: 1) ask the publisher for the actual script/source and review it so you can confirm it only uses your tokens to call the expected Google API; 2) verify which auth.profiles file it will read and avoid using high‑privilege or production credentials (use a limited sandbox account if possible); 3) if you cannot review the code, run it in an isolated environment or decline installation; and 4) prefer skills with verifiable source/homepage and included code or official provider plugins.
Capability Analysis
Type: OpenClaw Skill
Name: clawhub-publish-146230
Version: 2.0.0
The skill bundle is missing the primary execution script (scripts/generate.js), which is a significant red flag as the documentation (skill.md) explicitly states the tool accesses sensitive local OAuth credentials from 'auth-profiles.json'. It targets an internal Google sandbox endpoint (daily-cloudcode-pa.sandbox) and references non-public model versions ('Gemini 3 Pro'), making it impossible to verify if the credentials are being used legitimately or exfiltrated without the source code.
Capability Assessment
Purpose & Capability
Name/description (Antigravity/Gemini image generation) aligns with required binary (node) and declared config path (auth.profiles). However the skill claims to call an internal Google sandbox endpoint (daily-cloudcode-pa.sandbox) — acceptable for an internal tool but unusual for a third‑party skill with unknown source and no homepage.
Instruction Scope
SKILL.md instructs running /home/ubuntu/clawd/skills/antigravity-image-gen/scripts/generate.js and explicitly states it will read local OAuth tokens from auth-profiles.json. But this skill bundle contains no code files (only SKILL.md and _meta.json) — the referenced script is missing. Instructions also encourage using sensitive local OAuth credentials to access an internal endpoint, which increases risk if the actual script behaves differently.
Install Mechanism
No install spec (instruction-only), so nothing is written to disk by the skill installer itself. This is low-risk from an install mechanism perspective.
Credentials
The only declared config requirement is auth.profiles, which matches the instructions' stated need to read OAuth tokens. Reading OAuth credentials is sensitive but can be proportionate for an image-generation client that authenticates to an API. Still, the skill requests access to local OAuth tokens but provides no code to review, so the sensitivity is elevated.
Persistence & Privilege
The skill does not set always:true and does not request persistent system-wide privileges. Autonomous invocation is enabled by default, which is normal but should be considered along with the other concerns.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install clawhub-publish-146230 - After installation, invoke the skill by name or use
/clawhub-publish-146230 - Provide required inputs per the skill's parameter spec and get structured output
