UI Demo Agent Skill

Screenshot

by openai

vendor ×1

Use when the user explicitly asks for a desktop or system screenshot (full screen, specific app or window, or a pixel region), or when tool-specific capture capabilities are unavailable and an OS-level capture is needed.

Ios Simulator Browser

by openai

vendor

Mirror an iOS Simulator into the Codex in-app browser and render SwiftUI previews from importable Swift packages in that simulator with hot reload. Use when a user wants to watch or interact with an iOS app in the browser, see a SwiftUI preview outside Xcode Canvas, iterate live on a preview, or capture browser-visible simulator proof.

Doc Screenshots

by WordPress

Annotate UI screenshots with documentation callouts in Fellyph's established visual style — uniform-width orange arrows with white halos, double-stroke target outlines, numbered callout cards, dim overlays and a framed canvas. Use this whenever the user asks to annotate a screenshot, add arrows or callouts to a screenshot, create documentation images, highlight UI controls in a capture, or produce docs/tutorial visuals for Playground, Studio or any web UI — even if they just say "add arrows to this" or "make a docs screenshot".

Create Imessage Mockup

by gooseworks-ai

Render pixel-accurate iMessage screenshot mockups (DM or group) from a thread JSON. Supports minimal, with-keyboard, and full iPhone 15 Pro frame variants. Outputs HTML + PNG.

Goose Graphics Create Style

by gooseworks-ai

> End-to-end skill that turns a single reference image into a published Gooseworks style — analyzes the image, drafts the slim style spec, renders a hero example plus 2-3 additional formats via Playwright, writes the `gooseworks-style.json` manifest, and publishes via `npx gooseworks styles publish` so other agents can discover it. Mirrors goose-graphics-create-format but for styles.

Agent Canvas Setup

by majiayu000

Dependency checker and installer for agent-canvas, agent-eyes, and canvas-edit skills. Use BEFORE running any canvas skill for the first time, or when canvas skills fail with import/browser errors.
