SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Isolated frontend sandbox for rapid UI prototyping and live rendering on the canvas, so engineers and designers can iterate without modifying the main app.

Core Features & Use Cases

Isolated Vite dev server with iframe-based previews for every component
Prototype, compare variants side-by-side, and test responsive states (mobile/tablet/desktop)
Support companion skills (mockup-extract and mockup-graduate) and subagent delegation for design exploration

Quick Start

Boot the sandbox workflow and begin adding mockup components under artifacts/mockup-sandbox/src/components/mockups/.

FAQPage Schema

How do I prototype live UI components without modifying my main app?▼

You can prototype live UI components without modifying your main app by using an isolated Vite dev server with an iframe-based sandbox to render and iterate on mockups directly on the canvas.

Can I compare design variants side-by-side for responsive previews?▼

Yes, you can compare design variants side-by-side and test responsive states across mobile, tablet, and desktop views within the mockup sandbox environment.

How does subagent workflow orchestrate UI prototyping and design exploration?▼

Subagent workflows orchestrate UI prototyping by delegating design exploration tasks to isolated agents, enabling rapid iteration and variant generation without touching the main application codebase.

What's the best way to structure mockup components for live rendering?▼

The best way to structure mockup components is to add them under the artifacts/mockup-sandbox/src/components/mockups/ directory, utilizing optional resources folders for scripts, references, and assets.

Does the mockup sandbox support companion skills for extracting and graduating prototypes?▼

Yes, the mockup sandbox supports companion skills like mockup-extract and mockup-graduate to transfer prototyped components out of the sandbox and integrate them into the main application.

Are there limitations to using frontmatter-driven metadata in Vite component prototyping?▼

Frontmatter-driven metadata enforces safe usage by defining component boundaries and resource constraints, but requires strict adherence to schema rules to prevent rendering conflicts within the iframe preview routes.
