Creates interactive HTML playgrounds — self-contained single-file.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 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.

## How to use this skill

1. **Identify the playground type** from the user's request
2. **Load the matching template** from `templates/`:
   - `templates/design-playground.md` — Visual design decisions (components, layouts, spacing, color, typography)
   - `templates/data-explorer.md` — Data and query building (SQL, APIs, pipelines, regex)
   - `templates/concept-map.md` — Learning and exploration (concept maps, knowledge gaps, scope mapping)
   - `templates/document-critique.md` — Document review (suggestions with approve/reject/comment workflow)
   - `templates/diff-review.md` — Code review (git diffs, commits, PRs with line-by-line commenting)
…
