playground

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 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. Keep a single state object. Every control writes to it, every render reads from it. - Identify the playground type from the user's request - 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) - templates/code-map.md — Codebase architecture (component relationships, data flow, layer diagrams) - Follow the template to build the playground. If the topic doesn't fit any template cleanly, use the one closest and adapt. - Open in browser.
