Description
Generate images using the internal Google Antigravity API (Gemini 3 Pro Image). High quality, native generation without browser automation.
Usage Guidance
This skill is coherent with its stated purpose but handles sensitive OAuth tokens and contains an unexpected hard-coded project ID. Before installing or running it: (1) Inspect scripts/generate.js yourself (or have a trusted reviewer) to verify there are no hidden network destinations and to remove or change the fallback project ID; (2) Confirm the endpoint (daily-cloudcode-pa.sandbox.googleapis.com) and that you trust using an internal Google 'Antigravity' API; (3) Use a dedicated, limited-scope OAuth profile (not your main Google account) and consider revoking the token after use; (4) Run the script in a sandboxed environment first and monitor network/billing; (5) If you cannot validate the source or the project ID, do not provide production credentials or sensitive accounts. If you want, I can suggest specific code edits to remove the fallback project ID and limit what profile data is read.
Capability Analysis
Type: OpenClaw Skill
Name: sunshine-antigravity-image-gen
Version: 1.0.1
The skill reads sensitive OAuth tokens from the local `auth-profiles.json` file to authenticate requests to an internal Google sandbox API (daily-cloudcode-pa.sandbox.googleapis.com). While this behavior is documented and aligned with the stated purpose of image generation, the script (scripts/generate.js) employs high-risk patterns including direct credential access, a hardcoded project ID (junoai-465910), and spoofed headers (X-Goog-Api-Client) to interact with undocumented internal endpoints.
Capability Assessment
Purpose & Capability
Name/description align with the code and SKILL.md: the skill reads an OpenClaw auth-profiles.json entry named like 'google-antigravity' and calls an internal Google image endpoint. However, the script falls back to a hard-coded project ID (junoai-465910) if the profile lacks a projectId, which is unexpected for a client-side tool and could route requests/billing or telemetry to a third-party project.
Instruction Scope
SKILL.md explicitly instructs reading local OAuth tokens and running the provided Node script; the script only reads the declared auth-profiles path and writes an image file. This behavior is within the stated scope, but reading OAuth tokens is sensitive and the documentation accepts that the skill will access them.
Install Mechanism
No install spec; instruction-only with a single Node script. Requires Node on PATH. No remote downloads or archive extraction are performed by the skill itself.
Credentials
The skill requests access to the local auth-profiles JSON (auth.profiles), which is proportionate to authenticating to an internal API but is sensitive (contains OAuth tokens). The unexpected hard-coded fallback project ID is a clear red flag: it may cause requests to be associated with another project's billing/telemetry. The skill does not request unrelated secrets or environment variables, but access to auth-profiles gives it a high-value credential.
Persistence & Privilege
The skill is not always-enabled, does not modify other skills, and relies on manual invocation. It does not request elevated or persistent agent privileges.
