SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

It helps you avoid risky framework implementation by validating an approved design system in a capability-aware HTML/CSS/JS prototype before any production code is written.

Core Features & Use Cases

  • HTML/CSS/JS Prototype for Design Approval: Produce viewport-correct, clickable mockups that reflect approved tokens and approved component specs rather than generic UI.
  • Capability-Backed When Needed: Supports advanced surfaces (motion, media, WebGL/canvas, maps, charts, code editors, etc.) only when the skill’s capability and verification gates are satisfied.
  • Evidence-First Workflow With Anti-Slop: Uses a design expert reference flow and requires an anti-slop report tied to artifact evidence before claiming readiness.

Quick Start

Ask an AI coding assistant for a UI prototype based on your already-approved design system, for example: “Using the approved design system, build a web prototype/mockup that a reviewer can click through for visual approval.”

FAQPage Schema
How do I create a clickable HTML CSS JS mockup for design approval?

To create a clickable HTML CSS JS mockup, you need a capability-aware prototype that enforces design-system provenance and viewport configuration. This approach builds viewport-correct, clickable mockups reflecting approved tokens and component specs to enable visual approval before production coding.

What is design-system provenance in UI prototyping?

Design-system provenance in UI prototyping ensures that clickable mockups reflect approved design tokens and component specs rather than generic UI. It enforces traceability back to the approved design system, preventing unauthorized UI deviations during the HTML/CSS/JS prototype generation process.

Can I use HTML prototypes for mobile-native app simulations?

Yes, HTML prototypes support mobile-native HTML simulations, alongside web, extension, and desktop webview surfaces. You can build clickable flows and data-fed fixture-based demos for mobile-native environments using capability-aware HTML/CSS/JS mockups.

Does this prototyping approach support WebGL and canvas capabilities?

Yes, it supports advanced surfaces including WebGL, canvas, motion, media, maps, and charts. These capabilities are enabled only when capability-plan requirements and verification gates are satisfied, ensuring the HTML/CSS/JS prototype accurately reflects these advanced interactions.

What is an anti-slop report for prototype handoff readiness?

An anti-slop report for prototype handoff readiness is an evidence-bound document tied directly to artifact evidence. It is required before claiming readiness, ensuring the HTML/CSS/JS prototype meets stack-agnostic handoff standards through an evidence-first workflow with design expert reference validation.

What's the best way to validate a design system before writing production code?

The best way to validate a design system before writing production code is to build capability-aware HTML/CSS/JS prototypes. This produces viewport-correct clickable mockups for visual approval, preventing risky framework implementation by validating approved tokens and component specs beforehand.
