Does this skill support accessibility by default?

Yes, it strictly enforces the use of accessible primitives like Radix or Base UI and requires aria-labels for icon-only buttons.

Which animation library does this skill prefer?

The skill mandates the use of motion/react (formerly Framer Motion) for JavaScript-based animations and prefers CSS animations for micro-interactions.

Can this skill audit my existing code for errors?

Yes, by running /ui-skills , the skill will review the specified file for violations and provide concrete, code-level fixes.

Why does this skill prohibit 'h-screen'?

It requires the use of 'h-dvh' (dynamic viewport height) to ensure layout stability across mobile browsers that have dynamic toolbars.

How do I trigger the UI constraints during a chat?

Use the /ui-skills command to apply these constraints to all subsequent UI work in your current conversation with Claude.

The ui-skills plugin for Claude Code provides a rigorous framework for building production-grade frontend interfaces. It ensures consistency by mandating specific tech stacks like Tailwind CSS and motion/react, while enforcing strict rules regarding accessibility primitives, animation performance, and typography. By using this skill, developers can automate the review of their UI code against industry-standard patterns, avoiding common pitfalls like layout thrashing, inaccessible interactive elements, and inconsistent styling choices.
