FAQPage Schema
How do I create a UI mockup for quick review without a full development pipeline?

To create disposable UI components, generate self-contained artifacts with inline CSS and JS, realistic mock data, and interaction labeling. This approach bypasses the SDLC pipeline and security review for immediate discussion.

What is a disposable UI artifact and when do I need one?

A disposable UI artifact is a self-contained page or component used for review and discussion. You need one to visualize interaction states and realistic data without committing to production-ready code or security reviews.

Can I present error states and realistic data in a UI component mockup?

Yes, you can present error states and realistic data in a UI component mockup by using generation parameters to toggle error states and inject realistic mock data. This enables interaction labeling and comprehensive state presentation.

Does the mockup skill work with frontend-design for production-quality UI?

Yes, the mockup skill integrates with frontend-design if available. This integration allows you to upgrade disposable review artifacts into production-grade UI while handling inline CSS and JS.

What are the limitations of using disposable mockups for UI design?

Disposable mockups lack an SDLC pipeline and security review, limiting them to discussion and review contexts. They are not production-ready unless integrated with a dedicated frontend-design skill for production-grade output.
