UI/UX Pro Max - Design Intelligence
BM25 search engine-based UI/UX design intelligence for style, color, typography, layout, and UX decisions.
When to Use
Use proactively when:
- Building landing pages, dashboards, or web apps
- Choosing UI style, colors, or typography
- Designing for specific industries (SaaS, fintech, healthcare, etc.)
- Need design system recommendations
Triggers: design system, UI style, color palette, font pairing,
landing page design, glassmorphism, minimalism, brutalism,
design intelligence, style recommendation
Do NOT use for: backend code, API design, database, code review
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

Quick Reference
1. Accessibility (CRITICAL)
color-contrast - Minimum 4.5:1 ratio for normal textfocus-states - Visible focus rings on interactive elementsalt-text - Descriptive alt text for meaningful imagesaria-labels - aria-label for icon-only buttonskeyboard-nav - Tab order matches visual orderform-labels - Use label with for attribute
2. Touch & Interaction (CRITICAL)
touch-target-size - Minimum 44x44px touch targetshover-vs-tap - Use click/tap for primary interactionsloading-buttons - Disable button during async operationserror-feedback - Clear error messages near problemcursor-pointer - Add cursor-pointer to clickable elements
3. Performance (HIGH)
image-optimization - Use WebP, srcset, lazy loadingreduced-motion - Check prefers-reduced-motioncontent-jumping - Reserve space for async content
4. Layout & Responsive (HIGH)
viewport-meta - width=device-width initial-scale=1readable-font-size - Minimum 16px body text on mobilehorizontal-scroll - Ensure content fits viewport widthz-index-management - Define z-index scale (10, 20, 30, 50)
5. Typography & Color (MEDIUM)
line-height - Use 1.5-1.75 for body textline-length - Limit to 65-75 characters per linefont-pairing - Match heading/body font personalities
6. Animation (MEDIUM)
duration-timing - Use 150-300ms for micro-interactionstransform-performance - Use transform/opacity, not width/heightloading-states - Skeleton screens or spinners
Prerequisites
Check if Python is installed:
python3 --version || python --version
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:
- Searches 5 domains in parallel (product, style, color, landing, typography)
- Applies reasoning rules from
ui-reasoning.csv to select best matches
- Returns complete design system: pattern, style, colors, typography, effects
- 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 rulesdesign-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:
- When building a specific page (e.g., "Checkout"), first check
design-system/pages/checkout.md
- If the page file exists, its rules override the Master file
- 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
