What problem does it solve? Exploring visual, structural, or data-heavy decision spaces is hard to express in plain text. This Skill builds self-contained interactive HTML playgrounds where users adjust controls, see a live preview, and copy a natural-language prompt back into Claude. ## Core Features & Use Cases - Six Template Types: Design playgrounds, data explorers, concept maps, document critiques, diff reviews, and code architecture maps loaded from the templates directory. - Single-File Output: All CSS and JavaScript inlined with no external dependencies, so the playground works offline and never breaks from CDN failures. - Live Prompt Generation: A state-driven prompt output that updates on every control change, mentions only non-default choices, and includes a clipboard copy button. - Use Case: Ask for a design playground for card components, then adjust border radius, shadows, and spacing visually, pick a preset, and copy the generated prompt describing your choices back into the conversation. ## Quick Start Ask Claude to create an interactive playground for exploring card design options with adjustable shadows, spacing, and border radius.
