## What it does

The plugin ships a skill that generates a self-contained HTML file. Controls sit on one side, a live preview on the other, and the generated prompt waits at the bottom with a copy button. You tweak the controls, watch the result, then paste the prompt back into Claude.

Four templates cover the usual cases: `design-playground` for components, layouts, spacing, colour and typography, `data-explorer` for SQL, APIs, pipelines and regex, `concept-map` for concept maps and knowledge gaps, and `document-critique` for document review with approve, reject and comment actions.

Reach for it when the input space is large, visual or structural and plain text gets clumsy. A question that fits in two sentences does not need a playground — you would just add a step. Installation goes through the `claude-plugins-official` marketplace, and no API keys or extra dependencies are involved.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin install playground@claude-plugins-official
```
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-official
```

## When to use it
- generate an interactive HTML file for tuning parameters
- pick a layout, spacing scale and type pairing with live preview
- narrow down a SQL query or regex by trying variants
- map knowledge gaps on a topic as a concept map
- walk a document with approve and reject on each suggestion

## Example prompts
- build a playground for choosing the colour scheme and typography of a landing page
- make a data-explorer so I can shape a SQL query against the orders table
- I need a playground to review this document with approve and reject buttons

# Playground Plugin

Creates interactive HTML playgrounds — self-contained single-file explorers that let users configure something visually through controls, see a live preview, and copy out a prompt.

## What is a Playground?

A playground is a self-contained HTML file with:
- Interactive controls on one side
- A live preview on the other
- 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

Use this plugin 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.

## Templates

The skill includes templates for common playground types:
- **design-playground** — Visual design decisions (components, layouts, spacing, color, typography)
- **data-explorer** — Data and query building (SQL, APIs, pipelines, regex)
- **concept-map** — Learning and exploration (concept maps, knowledge gaps, scope mapping)
- **document-critique** — Document review (suggestions with approve/reject/comment workflow)

## Installation

Add this plugin to your Claude Code configuration to enable the playground skill.
```
