Playground

anthropics/claude-plugins-officialOfficial

Generates single-file HTML explorers where you adjust controls, see a live preview, and copy out a natural language prompt to bring back to Claude. Comes with six templates covering design systems, data queries, concept maps, document critique, code review, and architecture diagrams. The core pattern is smart: you configure visually what would be tedious to describe in text, then get a prompt that only mentions your non-default choices in conversational language. Everything updates live, no apply buttons. Most useful when the input space is large or structural, like tweaking component spacing or building a SQL query, where showing is faster than telling.

Files

Playground Builder

A playground is a self-contained HTML file with interactive controls on one side, a live preview on the other, and a prompt output at the bottom with a copy button. The user adjusts controls, explores visually, then copies the generated prompt back into Claude.

When to use this skill

When the user asks for an interactive playground, explorer, or visual tool for a topic — especially when the input space is large, visual, or structural and hard to express as plain text.
