SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Choosing a UI design direction from abstract descriptions is risky and slow. This Skill produces 2-3 disposable, interactive HTML mockup variants so you can compare visual directions side-by-side in a browser before committing to one. ## Core Features & Use Cases - Variant Generation: Builds 2-3 standalone HTML files, each taking a genuinely different design stance (density, emphasis, aesthetic, layout) rather than just different colors. - Structured Intake: Elicits feel, references, and core action before designing, so variants serve the actual user goal. - Visual Verification: Loads each variant in a browser and checks rendering with vision tools to catch layout bugs before delivery. - Opinionated Comparison: Delivers a multi-dimension comparison table with a clear recommendation, plus per-variant READMEs covering trade-offs. - Use Case: Ask for three takes on a knowledge-base app home screen; receive calm-editorial, utilitarian-dense, and split-pane variants you can open and click through, then pick a winner. ## Quick Start Sketch three design variants for my app's dashboard screen so I can compare layout directions before building it.

FAQPage Schema
How do I compare UI design directions before building?

Use this skill to generate 2-3 standalone HTML mockup variants, each taking a different design stance such as density, emphasis, or layout. Open them in a browser, compare them side-by-side, and pick a winner or request a hybrid.

What makes good design mockup variants for comparison?

Variants should differ along a meaningful axis like density, emphasis, aesthetic, or layout, not just accent colors. Each should be a self-contained interactive HTML file with realistic content so differences are tangible when clicked through.

When should I not use HTML sketch mockups?

Do not use sketching when you need production-ready components, polished one-off artifacts like landing pages, or diagrams. In those cases use a proper design/build workflow instead, since sketches are disposable prototypes.

Does the sketch skill work with an existing design theme?

Yes. If the project has a visual identity, shared tokens like colors and fonts can go in a sketches/themes/tokens.css file imported by each variant. Keep tokens minimal since sketches are throwaway.

How interactive should a UI sketch prototype be?

A sketch needs at least one clickable primary action with a visible result, one meaningful state transition like a filter or toggle, and hover affordances on buttons or rows. More than that is over-engineering a disposable mockup.
