SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill turns unclear requirements into a visual, interactive HTML playground so users can configure options with controls, preview changes instantly, and copy a ready-to-use prompt.

Core Features & Use Cases

  • Interactive single-file playgrounds: Generates self-contained HTML with inline CSS/JS and a live preview.
  • Control-to-preview state management: Uses a single state object where every control updates and re-renders immediately.
  • Actionable prompt output: Produces a natural-language prompt that includes enough context to act without seeing the playground, mentioning only non-default choices.
  • Copy-friendly: Includes a copy button with quick feedback so users can paste into Claude.
  • Template-driven variants: Uses specialized templates for design, data exploration, concept maps, document critique, diff/code review, and codebase architecture.
  • Dark-theme UX + presets: Starts with sensible defaults, includes multiple cohesive presets, and keeps the UI readable in dark mode.

Quick Start

Ask Claude: Create a design playground for a pricing-card component with sliders for spacing, border radius, and shadow, plus 3–5 presets, and output the HTML as a single file.

Frequently Asked Questions about playground

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

FAQPage Schema
How do I generate an interactive HTML playground for visual design configuration?▼

An interactive HTML playground is a single-file, dependency-free page with inline CSS and JS that provides live preview and state-driven UI controls for immediate re-rendering. It allows users to visually configure design options and instantly see the changes without external libraries.

How do I create an actionable prompt from visual UI controls?▼

You create an actionable prompt by adjusting state-driven UI controls in the generated playground, which then outputs a natural-language prompt describing only your non-default choices. This provides enough context to execute the task independently without needing the visual playground.

Can I build a single-file HTML template without external dependencies?▼

Yes, you can build a single-file HTML template without external dependencies because the Skill generates self-contained pages with inline CSS and JS. This ensures the dark-themed live preview works immediately in any browser without requiring external libraries or build tools.

Does the live preview support presets for data exploration and concept maps?▼

Yes, the live preview supports presets for data exploration and concept maps through template-driven variants tailored to these specific workflows. The playground starts with sensible defaults and includes multiple cohesive presets to maintain readable dark mode UI across different use cases.

What is the best way to critique document diffs using an interactive template?▼

The best way to critique document diffs is using a specialized template-driven playground variant designed for diff and code review workflows. It generates a dark-themed interactive HTML interface with state-driven controls to visually analyze changes and output an actionable critique prompt.
