Baseline UI

Enforces an opinionated UI baseline to prevent AI-generated interface slop.

When to Use

You are building or reviewing Tailwind-based UI and want a strict baseline for accessibility, motion, typography, and layout.
The task is to prevent generic or sloppy AI-generated interface decisions before they spread through the codebase.
You need concrete UI constraints to apply to a file review or an ongoing frontend implementation.

How to use

/baseline-ui Apply these constraints to any UI work in this conversation.
/baseline-ui <file> Review the file against all constraints below and output:
- violations (quote the exact line/snippet)
- why it matters (1 short sentence)
- a concrete fix (code-level suggestion)

Stack

MUST use Tailwind CSS defaults unless custom values already exist or are explicitly requested
MUST use motion/react (formerly framer-motion) when JavaScript animation is required
SHOULD use tw-animate-css for entrance and micro-animations in Tailwind CSS
MUST use cn utility (clsx + tailwind-merge) for class logic

Components

MUST use accessible component primitives for anything with keyboard or focus behavior (Base UI, React Aria, Radix)
MUST use the project’s existing component primitives first
NEVER mix primitive systems within the same interaction surface
SHOULD prefer Base UI for new primitives if compatible with the stack
MUST add an aria-label to icon-only buttons
NEVER rebuild keyboard or focus behavior by hand unless explicitly requested

Interaction

MUST use an AlertDialog for destructive or irreversible actions
SHOULD use structural skeletons for loading states
