Desktop Mockup

Create a real website screenshot inside a light Chrome window with tab, address bar, rounded corners, and shadow. Deliver the framed image; a raw screenshot alone is incomplete.

Defaults

Use local headless Chromium, a 1440 × 900 content viewport, 2× capture/export, and transparent PNG output. Use the requested URL's hostname in the frame, and the page title in the tab. Save in the task's output directory or a new folder under ~/Documents/website-mockups/.

Use ScreenshotAPI when the user chooses scale, batch/hosted capture, or explicitly requests it. Read hosted capture for that branch. Creating a paid plan or subscription requires a separate request.

Create

1. Resolve the target URL from the user or current artifact. Ask only if no target is available.
2. Find this skill's installation directory. For first use, follow setup: Node.js 20+, npm ci, then npm run setup. Each skill contains its own renderer and assets; it works independently of the other mockup skill. Existing bundled Playwright packages are optional.

3. From this skill folder run:

   npm run capture -- --url https://example.com/ --out ./output

   Substitute the actual URL and output directory. Run node scripts/capture.cjs --help for supported options. The browser runs in the background without a visible window.

4. Inspect capture.png and mockup.png. Verify the real page, loaded fonts/images, correct address/title, complete frame, preserved proportions, and unobstructed content. Read back dimensions and transparency. A blocked or incomplete page is a failed capture, not a successful mockup.
5. Return the mockup inline and link the PNG. Link slide.png when requested. Retain the source capture, self-contained HTML, and metadata beside it.

Customize

Read command options for viewport dimensions, a requested page section, an existing PNG, background color, or a 4K slide export. Inspect the current DOM before using --hide to suppress an obstructive popup or chat widget only within the capture session. Preserve meaningful page content.

The helper captures one viewport. For a full-page request, choose a section, separate captures, or an explicitly tall frame; preserve readable proportions. Existing images must match the intended viewport aspect ratio, which the helper checks.

Keep website pixels intact through deterministic HTML/CSS framing. The Chrome controls are illustrative. Personalized content and tracking numbers may vary between sessions. Use consistent capture preparation for comparisons.
