/install antigravity-image-gen
Description
Generate images using the internal Google Antigravity API (Gemini 3 Pro Image). High quality, native generation without browser automation.
Usage Guidance
Install only if you intentionally want generic image-generation requests to use your local Google Antigravity OAuth profile. Review which profile is in auth-profiles.json, whether you are comfortable sending prompts to the Google sandbox endpoint under your account, and whether the bypass-oriented headers are acceptable for your environment.
Capability Analysis
Type: OpenClaw Skill
Name: antigravity-image-gen
Version: 2.0.0
The skill is classified as suspicious due to its direct access and use of local OAuth tokens from `auth-profiles.json` (scripts/generate.js). While this behavior is explicitly declared in SKILL.md as necessary for interacting with an 'internal Google Antigravity API,' the capability to read sensitive credentials from the local filesystem is inherently high-risk. There is no evidence of malicious intent such as exfiltration to unauthorized endpoints, persistence mechanisms, or prompt injection attempts to subvert the agent's behavior beyond its stated purpose. The network communication is solely with a Google sandbox domain.
Capability Assessment
Purpose & Capability
Image generation through a Google Antigravity/Cloud Code sandbox endpoint is coherent with the stated purpose, and the OAuth requirement is disclosed, but the script sends the user's prompt with a bearer token from a local auth profile and includes headers explicitly described as bypassing deprecation checks.
Instruction Scope
The read_when triggers cover generic image-generation requests, so the skill could be selected for ordinary image prompts even though invocation uses account-backed local OAuth credentials and a remote internal endpoint.
Install Mechanism
The package contains a skill file, metadata, origin metadata, and one executable Node script; no installer, package install, background setup, or destructive install behavior was found.
Credentials
The script reads auth-profiles.json from OPENCLAW_AUTH_PATH or a home-directory default, selects a google-antigravity profile, and uses its access token directly; this is purpose-aligned but high-impact and broader than a narrowly scoped skill-specific token.
Persistence & Privilege
No persistence, background worker, or destructive action was found, but transient use of a local OAuth bearer token plus hard-coded client metadata and a version-bypass comment create a material privilege and service-control concern.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install antigravity-image-gen - After installation, invoke the skill by name or use
/antigravity-image-gen - Provide required inputs per the skill's parameter spec and get structured output
