UI/UX Pro Max - Design Intelligence

BM25 search engine-based UI/UX design intelligence for style, color, typography, layout, and UX decisions.

When to Apply

Reference these guidelines when:

• Designing new UI components or pages
• Choosing color palettes and typography
• Reviewing code for UX issues
• Building landing pages or dashboards
• Implementing accessibility requirements

Rule Categories by Priority

Priority	Category	Impact	Domain
1	Accessibility	CRITICAL	ux
2	Touch & Interaction	CRITICAL	ux
3	Performance	HIGH	ux
4	Layout & Responsive	HIGH	ux
5	Typography & Color	MEDIUM	typography, color
6	Animation	MEDIUM	ux
7	Style Selection	MEDIUM	style, product
8	Charts & Data	LOW	chart

Quick Reference

1. Accessibility (CRITICAL)

• color-contrast - Minimum 4.5:1 ratio for normal text
• focus-states - Visible focus rings on interactive elements
• alt-text - Descriptive alt text for meaningful images
• aria-labels - aria-label for icon-only buttons
• keyboard-nav - Tab order matches visual order
• form-labels - Use label with for attribute

2. Touch & Interaction (CRITICAL)

• touch-target-size - Minimum 44x44px touch targets
• hover-vs-tap - Use click/tap for primary interactions
• loading-buttons - Disable button during async operations
• error-feedback - Clear error messages near problem
• cursor-pointer - Add cursor-pointer to clickable elements

3. Performance (HIGH)

• image-optimization - Use WebP, srcset, lazy loading
• reduced-motion - Check prefers-reduced-motion
• content-jumping - Reserve space for async content

4. Layout & Responsive (HIGH)

• viewport-meta - width=device-width initial-scale=1
• readable-font-size - Minimum 16px body text on mobile
• horizontal-scroll - Ensure content fits viewport width
• z-index-management - Define z-index scale (10, 20, 30, 50)

5. Typography & Color (MEDIUM)

• line-height - Use 1.5-1.75 for body text
• line-length - Limit to 65-75 characters per line
• font-pairing - Match heading/body font personalities

6. Animation (MEDIUM)

• duration-timing - Use 150-300ms for micro-interactions
• transform-performance - Use transform/opacity, not width/height
• loading-states - Skeleton screens or spinners

How to Use This Skill

When user requests UI/UX work (design, build, create, implement, review, fix, improve), follow this workflow:

Step 1: Analyze User Requirements

Extract key information from user request:

• Product type: SaaS, e-commerce, portfolio, dashboard, landing page, etc.
• Style keywords: minimal, playful, professional, elegant, dark mode, etc.
• Industry: healthcare, fintech, gaming, education, etc.
• Stack: React, Vue, Next.js, or default to html-tailwind

Step 2: Generate Design System (REQUIRED)

Always start with --design-system to get comprehensive recommendations with reasoning:

python3 skills/ui-ux-pro-max/scripts/search.py "<product_type> <industry> <keywords>" --design-system [-p "Project Name"]

This command:

1. Searches 5 domains in parallel (product, style, color, landing, typography)
2. Applies reasoning rules from ui-reasoning.csv to select best matches
3. Returns complete design system: pattern, style, colors, typography, effects
4. Includes anti-patterns to avoid

Example:

python3 skills/ui-ux-pro-max/scripts/search.py "beauty spa wellness service elegant" --design-system -p "Serenity Spa"

Step 2b: Persist Design System (Master + Overrides Pattern)

To save the design system for hierarchical retrieval across sessions, add --persist:

python3 skills/ui-ux-pro-max/scripts/search.py "<query>" --design-system --persist -p "Project Name"

This creates:

• design-system/MASTER.md - Global Source of Truth with all design rules
• design-system/pages/ - Folder for page-specific overrides

With page-specific override:

python3 skills/ui-ux-pro-max/scripts/search.py "<query>" --design-system --persist -p "Project Name" --page "dashboard"

How hierarchical retrieval works:

1. When building a specific page (e.g., "Checkout"), first check design-system/pages/checkout.md
2. If the page file exists, its rules override the Master file
3. If not, use design-system/MASTER.md exclusively

Step 2c: Use Existing DESIGN.md (Google Stitch Format)

If the project already has a DESIGN.md in the root (e.g., from awesome-design-md), skip design system generation and use it directly. DESIGN.md follows the 9-section Stitch format (visual theme, colors, typography, components, layout, depth, do/don'ts, responsive, agent prompts) and serves as the single source of truth for all UI decisions.

Install a brand DESIGN.md:

npx getdesign@latest add {brand}     # e.g., vercel, stripe, linear.app
npx getdesign@latest list             # show all 66 available brands

Available brands: airbnb, apple, claude, cursor, figma, linear.app, notion, stripe, supabase, tesla, vercel, and 55 more.

Template: Use templates/visual-design.template.md to create a custom DESIGN.md from scratch.

Step 3: Supplement with Detailed Searches (as needed)

After getting the design system, use domain searches to get additional details:

python3 skills/ui-ux-pro-max/scripts/search.py "<keyword>" --domain <domain> [-n <max_results>]

When to use detailed searches:

Need	Domain	Example
More style options	style	--domain style "glassmorphism dark"
Chart recommendations	chart	--domain chart "real-time dashboard"
UX best practices	ux	--domain ux "animation accessibility"
Alternative fonts	typography	--domain typography "elegant luxury"
Landing structure	landing	--domain landing "hero social-proof"

Step 4: Stack Guidelines (Default: html-tailwind)

Get implementation-specific best practices. If user doesn't specify a stack, default to html-tailwind.

python3 skills/ui-ux-pro-max/scripts/search.py "<keyword>" --stack html-tailwind

Available stacks: html-tailwind, react, nextjs, astro, vue, nuxtjs, nuxt-ui, svelte, swiftui, react-native, flutter, shadcn, jetpack-compose

Common Rules for Professional UI

Icons & Visual Elements

Rule	Do	Don't
No emoji icons	Use SVG icons (Heroicons, Lucide, Simple Icons)	Use emojis as UI icons
Stable hover states	Use color/opacity transitions on hover	Use scale transforms that shift layout
Correct brand logos	Research official SVG from Simple Icons	Guess or use incorrect logo paths
Consistent icon sizing	Use fixed viewBox (24x24) with w-6 h-6	Mix different icon sizes randomly

Interaction & Cursor

Rule	Do	Don't
Cursor pointer	Add cursor-pointer to all clickable elements	Leave default cursor on interactive elements
Hover feedback	Provide visual feedback (color, shadow, border)	No indication element is interactive
Smooth transitions	Use transition-colors duration-200	Instant state changes or too slow (>500ms)

Light/Dark Mode Contrast

Rule	Do	Don't
Glass card light mode	Use bg-white/80 or higher opacity	Use bg-white/10 (too transparent)
Text contrast light	Use #0F172A (slate-900) for text	Use #94A3B8 (slate-400) for body text
Muted text light	Use #475569 (slate-600) minimum	Use gray-400 or lighter
Border visibility	Use border-gray-200 in light mode	Use border-white/10 (invisible)

Pre-Delivery Checklist

Before delivering UI code, verify:

Visual Quality

• No emojis used as icons (use SVG instead)
• All icons from consistent icon set (Heroicons/Lucide)
• Brand logos are correct (verified from Simple Icons)
• Hover states don't cause layout shift

Interaction

• All clickable elements have cursor-pointer
• Hover states provide clear visual feedback
• Transitions are smooth (150-300ms)
• Focus states visible for keyboard navigation

Light/Dark Mode

• Light mode text has sufficient contrast (4.5:1 minimum)
• Glass/transparent elements visible in light mode
• Borders visible in both modes

Layout

• No content hidden behind fixed navbars
• Responsive at 375px, 768px, 1024px, 1440px
• No horizontal scroll on mobile

Accessibility

• All images have alt text
• Form inputs have labels
• Color is not the only indicator
• prefers-reduced-motion respected
