To extract a UI component into a mockup sandbox, the skill automatically copies the component and its dependencies, rewrites imports, and stubs external dependencies for isolated redesign. It embeds the extracted component in an iframe on the canvas for visual comparison.

The best way to isolate a navigation bar for redesign is using a mockup sandbox that automatically handles dependency stubbing and import rewriting. This extracts the component into an iframe on the canvas, ensuring the main app remains completely unaffected during visual iteration.

Yes, you need codebase access to extract components and stub external dependencies. The extraction process automatically analyzes the source code to identify required dependencies, rewrites their imports, and stubs external calls so the component functions correctly within the isolated mockup sandbox.

Iframe embedding works by taking the extracted UI component and rendering it within an isolated frame directly on the canvas. This mechanism ensures that the stubbed external dependencies and rewritten imports operate securely, providing a self-contained visual reference for design iteration.

Yes, you can create design variants without manually copying files by automatically extracting the component into a mockup sandbox. The process handles dependency resolution and import rewriting, allowing you to iterate on visual variants safely isolated from your main application codebase.

A limitation of stubbing external dependencies is that complex external services or global providers may not function perfectly within the sandbox. While the skill rewrites imports to enable basic component rendering in the iframe, highly integrated application logic might require manual stub adjustments for accurate visual iteration.
