SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The Mockup Sandbox Skill provides a self-contained frontend sandbox for rapid UI prototyping, enabling live component rendering and iframe-based previews on the canvas without touching the main app.

Core Features & Use Cases

  • Isolated frontend sandbox with a Vite dev server and /__mockup/ preview routes for embedding components on a canvas.
  • Supports design variants via subagents and placeholder 'building' states to provide immediate feedback during iteration.
  • Provides a structured workflow with artifacts under artifacts/mockup-sandbox and a component registry for mockup components.

Quick Start

Launch the mockup sandbox component preview server and begin creating mockup components under artifacts/mockup-sandbox/src/components/mockups.

Frequently Asked Questions about mockup-sandbox

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I prototype UI components in an isolated sandbox?▼

You can prototype UI components in an isolated sandbox using a self-contained Vite dev server with /__mockup/ preview routes, rendering live components via iframe on the workspace canvas without modifying the main application.

What is the best way to iterate and compare UI design variants?▼

The best way to iterate and compare UI design variants is by using companion DESIGN subagents to generate variations alongside placeholder 'building' states, ensuring safe, repeatable mockups with immediate visual feedback during the iteration process.

How do I preview responsive layouts without affecting my main app?▼

You can preview responsive layouts without affecting your main app by embedding live renderings directly on the workspace canvas through isolated iframe routes under __mockup/preview, keeping the mockup environment completely self-contained.

Do I need a specific project structure to create mockup components?▼

Yes, you need a structured project workflow where mockup components are organized under artifacts/mockup-sandbox/src/components/mockups, utilizing a component registry to ensure safe, repeatable mockups and proper artifact management.

Can I use this sandbox for rapid frontend design exploration?▼

Yes, you can use this sandbox for rapid frontend design exploration as it provides a self-contained environment specifically built for quick UI prototyping, enabling live component rendering and immediate feedback during iteration.

Why use placeholder building states during UI mockup iteration?▼

Placeholder 'building' states provide immediate visual feedback during UI mockup iteration, allowing you to see rendering progress within the isolated iframe preview while companion subagents generate and compare design variants safely.
