UI/UX Excellence Prover: Ending the Era of Lifeless AI Interfaces

With the UI/UX Excellence Prover, your agent starts thinking like a senior designer. It checks for spatial hierarchy, motion tokens, and 8-state microinteractions before you ever see the final code. You get a polished, production-ready interface that feels premium because it follows the rules of high-end design.

Before you connect

Questions about UI/UX Excellence Prover.

The practical details behind the request, access and result.

What is the UI/UX Excellence Prover MCP?

It is a design audit capability that forces your AI agent to follow professional UI/UX standards, including spatial hierarchy, motion physics, and accessibility rules.

How does this help with accessibility?

It ensures your AI-generated components meet WCAG 2.2 AAA standards by checking for contrast, aria-labels, and keyboard navigation automatically.

Can it fix my button interactions?

Yes, it enforces an 8-state interaction model for every button, ensuring you have states for hover, focus, loading, success, and error.

Does it support dark mode?

It ensures dark mode is implemented via surface lightness variation rather than simple color inversion, maintaining proper spatial hierarchy.

What is a dark pattern in this context?

The Connector identifies and flags deceptive designs like pre-checked boxes, hidden costs, and forced infinite scrolls that trick users.

How does it handle motion?

It replaces generic CSS animations with spring physics and motion tokens that explain, guide, or confirm user actions at 60fps.

Does it generate UI designs or code?

No. The agent designs or codes the interface. The capability VALIDATES that it meets 2026-era standards across six pillars: spatial hierarchy, spring motion, 8-state microinteractions, 8px rhythm, WCAG 2.2 AAA neuro-inclusive accessibility, and Calm UI principles. It coaches. not generates.

Why 8 states per interactive element?

Because a button without feedback is a dead rectangle. The 8 states (idle, hover, active, focus-visible, disabled, loading, success, error) cover every moment of interaction. Each state uses spring physics for natural transitions. Without all 8, users cannot perceive affordance, progress, or outcome.

What is Calm UI and why does it matter?

Calm UI is the 2026 shift from 'time on page' to 'time well spent'. It rejects dark patterns: infinite scroll without end states, auto-play media, fake urgency, hidden opt-outs. It implements intentional friction for destructive actions, progressive disclosure, and natural stopping points. Respect > engagement.
