SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Turning a UI idea into something visual usually requires a framework setup, a build step, or a slow Figma round-trip. This Skill converts a short brief into a self-contained HTML mockup in minutes, so design directions can be explored and demoed before any framework commitment. ## Core Features & Use Cases - Single-file mockup generation: Produces one .html file with inline CSS and minimal inline JS, no build step or framework required. - Reference and token support: Anchors output to a visual reference (file or URL) and can inherit project design tokens from .lovable/memory/style/ or .claude/engineering/design-archive/. - Configurable copy tiers: Choose between lorem ipsum, descriptive placeholders, or pack-voice copy gated behind compliance checks. - Use Case: Before a customer call, run the skill with a brief like "dashboard showing 5-10 active cases with status chips" to get a presentable HTML artifact, then fork it into variants with /design-shotgun. ## Quick Start Ask the agent to run /design-html with a short UI brief, for example: generate a single-file HTML mockup of a dashboard for tracking active support cases with status chips.

Frequently Asked Questions about design-html

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate a quick HTML mockup from a design brief?▼

Run /design-html with a short prose brief describing the target surface, user task, and layout hints. The skill produces a single self-contained .html file with inline CSS that you can open directly in a browser via /open-managed-browser.

How to create UI mockups without a framework or build step?▼

Use a single-file HTML approach where all CSS is inlined in a <style> tag and any interactivity uses minimal inline JavaScript. This skill enforces exactly that constraint, producing portable files openable in any browser.

Can I use my project's existing design tokens in generated mockups?▼

Yes, pass the --inherit-project flag to load color, spacing, and type tokens from .lovable/memory/style/ or .claude/engineering/design-archive/. Without it, the skill falls back to defaults like system fonts and an 8px spacing scale.

When should I not use a single-file HTML mockup?▼

Avoid it for production code, multi-page flows with shared state, or pixel-perfect Figma exports. The single-file constraint becomes painful for stateful flows, and the output is a mockup, not a reusable component.

What happens if the brief is too vague to generate from?▼

The skill asks one targeted clarifying question before generating rather than producing a wasted output. It also handles unreadable token files and blocked reference URLs by falling back to defaults and noting the gap in its report.
