HTML Design Prototypes

**TRIGGER: about to populate `AskUserQuestion` options with `preview:` content for any visual UI / screen / layout / component / animation comparison.** STOP and ask the user one short question first: *"Would you like a quick inline chip comparison, or a full HTML prototype you can open in the browser?"* The chip is fast but flattens color, type, spacing, and motion into monospace text; the HTML prototype is heavier but real. Asking costs one question; skipping costs a full redo if they wanted HTML — always ask. **No carve-out for "simulate", "demo", "mock up", "quick decision" — those framings name the surface, not an exception.** When the user picks HTML, this skill creates HTML prototypes for visual design, component playgrounds, animation tuning, and design system exploration — even when the final surface is React, Swift, SwiftUI, Android, or another framework. Use whenever the user wants to mock, prototype, sketch, tune, or explore any UI element — components, animations, transitions, layouts, design systems — before committing to production code. HTML is the fastest design-thinking surface; reach for it even for non-web targets. For N alternatives use html-brainstorm-grid; for a single tunable component use this skill.

From the source SKILL.md

HTML is the fastest design surface available — instant feedback loop, real layout engine, real typography, real interaction. Use it to sketch designs even when the production target is React Native, Swift, or anything else. The translation from HTML+CSS to the final framework is mechanical; the design exploration is what's hard.

What this skill does

HTML Design Prototypes is a community-contributed Claude Code skill in the design-system-ui sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/html-design-prototypes/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use whenever the user wants to mock, prototype, sketch, tune, or explore any UI element — components, animations, transitions, layouts, design systems — before committing to production code. HTML is the fastest design-thinking surface; reach for it even for non-web targets.
