What This Skill Does

Generates high-quality images by calling the internal Google Antigravity API (Gemini 3 Pro Image) directly using local OAuth credentials, without browser automation. Accepts a text prompt and optional aspect ratio, then saves the image to a specified path.

Replaces browser-based image generation tools and manual screenshot workflows by providing native API access with simple command-line arguments.

When to Use It

  • Generate a futuristic cityscape on Mars for a presentation slide
  • Create a 16:9 banner image for a blog post or social media
  • Produce a square product mockup image from a text description
  • Generate multiple concept art images for a design brainstorming session
  • Create an illustration for a research paper or internal document

Install

$ openclaw skills install @ipedrax/antigravity-image-gen

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

/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.

Playwright (Automation + MCP + Scraper)

@ivangdavila

Automates, tests, and debugs browsers with Playwright: locators, auto-waiting, traces, CI runs, and MCP browser control. Use when a test is flaky, times out, or fails only in CI or headless; when a locator matches multiple elements or the wrong one (strict mode violation); when clicks need force, waits become sleeps, or networkidle never settles; for storageState and login setup, request mocking and HAR replay, uploads and downloads, iframes and shadow DOM, popups and dialogs, screenshot diffs that change per machine, trace and report artifacts, sharding a slow suite, device and permission emulation, accessibility checks, driving a real browser through Playwright MCP, extracting data from JS-rendered pages, or porting a Cypress, Puppeteer, or Selenium suite to Playwright. Not for maintaining an existing Cypress or Puppeteer suite (cypress, puppeteer) or for work a plain HTTP request answers (http).

YouTube

@byungkyu

YouTube Data API integration with managed OAuth. Search videos, manage playlists, access channel data, and interact with comments. Use this skill when users want to interact with YouTube. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway). Calls run through the `maton` CLI with OAuth login, or over raw HTTP with a Maton API key where the CLI cannot be installed. Every call is authenticated as the user's connection and reaches only what that connection's authorization allows, which the provider enforces on every request; the endpoints documented here are the ones this skill uses, and any other endpoint of this app needs the user to ask for it by name. Default to read and list calls, and confirm every write or new connection with the user. This file also documents the three constructs that turn a YouTube connection into automation, in the order they are used: the connection (the first step), a hosted function that runs a YouTube action through the Maton SDK, and a trigger that calls that function on a schedule or on an event. Those sections are the platform's own reference text, shared with the api-gateway skill, with YouTube examples; they add no YouTube capability - YouTube is not an event source, a trigger cannot read YouTube data, and the files under `references/<source>/triggers.md` are the platform's event catalogues for the sources Maton offers (time, Calendly, GitHub, Gmail, HubSpot, Linear, Notion, Slack, Stripe).
