General guidance for building UI with Tailwind CSS: responsive and state variants, dark mode, sparing arbitrary values, components before @apply, and pitfalls such as dynamically built class names missing in production, with button and hero examples.

Gives the agent three exact Tailwind arbitrary-value shadow utilities (sm, md, lg) for layered, neutral elevation on cards, controls, popovers and hero media, with rules against mixing them with default shadows, tinting or stacking.

Adds thin vertical guide lines at the content container edges plus small corner squares for a measured, structured layout, with CSS tokens and pseudo-element code that keeps guides behind content and out of pointer events.

Creates a layered progressive blur at the top or bottom edge of the viewport by stacking backdrop-filter layers with gradient masks, with ready-to-paste HTML and CSS and knobs for height, blur steps, direction and z-index.

Applies the concrete rules from Refactoring UI to design and fix interfaces: pick spacing, type, color and shadow values from fixed scales, build hierarchy with weight and color rather than size, and create depth with emulated light. Useful when a UI looks amateur, cluttered or off.

Works in the OKLCH color space for web projects: converts hex, rgb and hsl to oklch, generates palettes and dark-mode scales without hue drift, checks APCA and WCAG contrast and fixes it via lightness, handles P3 gamut fallbacks, and themes Tailwind v4.

Designs or restyles web UIs in a neo-industrial, editorial-brutalist style: sets a mode, one dominant gesture, a grid and a single accent color, builds type hierarchy and layout from macro to micro, and reviews the rendered page at desktop and phone widths.

Applies a Swiss International Style design system with Tailwind CSS: a 12-column grid on an 8px base, IBM Plex Sans with light headings, a stone palette, hierarchy through opacity rather than hue, a single accent color, body text capped at 60ch, mobile-first layouts and dark mode.

Styles elevated surfaces such as cards, dialogs, popovers and toasts with smooth-shadow-ring utilities instead of pairing a border or ring with a shadow, avoiding the double-edge look. Covers ring and shadow tinting, dark mode and overrides. Requires the shadow-plugin Tailwind plugin.

Builds frosted and liquid-glass UI: backdrop-filter blur, translucent fills, bright edge highlights and layered shadows, SVG displacement for refraction, hover, scroll and entrance motion, plus accessible reduced-transparency fallbacks.

Builds compact, polished landing pages for dev tools, package demos and micro-SaaS. Picks a design fingerprint (composition, palette, type, radius, surfaces, motion) so each run looks different, features a product-native demo, and keeps zero layout shift, focus states and reduced motion.

When the agent changes a single CSS value or Tailwind class in a Next.js App Router project, a floating bar appears on the page so you can fine-tune it with arrow keys before persisting. Loads a runtime script from budge.design in app/layout.tsx.

Reduces CSS custom properties and Tailwind v4 design tokens in globals.css without changing visuals: maps usage to find live tokens, deletes dead ones, collapses values similar in light and dark modes via a scripted rename map, and verifies with typecheck, lint and build.
