How does it handle animation performance?

It mandates animating only compositor properties (transform and opacity) and prevents the animation of layout properties like width or height to ensure 60fps performance.

Does it work with custom design systems?

While it has opinionated defaults, it respects existing project tokens and custom values if they are already present in your codebase.

What frontend stack does this skill support?

The skill is optimized for Tailwind CSS, motion/react (formerly Framer Motion), and accessible primitives like Radix, Base UI, and React Aria.

How do I invoke the UI Skills plugin?

You can use the command `/ui-skills` to apply constraints to your current conversation or `/ui-skills ` to audit a specific file for violations and receive concrete fixes.

Can this skill help with web accessibility (a11y)?

Yes, it strictly enforces the use of ARIA labels for icon-only buttons and requires the use of accessible primitives to handle keyboard and focus behavior correctly.

Design Tools

Enforces opinionated frontend constraints and accessibility standards for building high-quality, performant user interfaces.

UI Interface Guardrails is a specialized skill for Claude Code that implements a comprehensive set of design and development constraints for frontend engineering. It ensures that UI work adheres to modern best practices, including Tailwind CSS defaults, accessible component primitives like Radix and Base UI, and performance-optimized animations. By providing automated auditing and specific implementation patterns, this skill helps developers maintain consistency, accessibility, and high performance while preventing common anti-patterns like layout shifts or inaccessible interaction surfaces.

Key Features

01Enforcement of accessible component primitives (Radix, Base UI, React Aria)

02Constraint-based layout management using fixed z-index scales and safe-area-insets

03Standardized typography rules including text-balance, text-pretty, and tabular-nums

04Performance-first animation guidelines using motion/react and compositor-only properties

05Automated UI code auditing against strict accessibility and design constraints

Use Cases

01Auditing existing component files to identify and fix accessibility violations or poor CSS practices

02Ensuring consistent animation performance and interaction feedback across a large codebase

03Scaffolding new frontend features with pre-defined constraints for Tailwind CSS and Framer Motion
