How to Use
Search specific domains using the CLI tool below.
Prerequisites
Check if Python is installed:
python3 --version || python --version
If Python is not installed, install it based on user's OS:
macOS:
brew install python3
Ubuntu/Debian:
sudo apt update && sudo apt install python3
Windows:
winget install Python.Python.3.12
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" --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"
This also creates:
design-system/pages/dashboard.md — Page-specific deviations from Master
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
Context-aware retrieval prompt:
I am building the [Page Name] page. Please read design-system/MASTER.md.
Also check if design-system/pages/[page-name].md exists.
If the page file exists, prioritize its rules.
If not, use the Master rules exclusively.
Now, generate the code...
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, vue, nuxtjs, nuxt-ui, svelte, swiftui, react-native, flutter, shadcn, jetpack-compose

Example Workflow
User request: "Làm landing page cho dịch vụ chăm sóc da chuyên nghiệp"
Step 1: Analyze Requirements
- Product type: Beauty/Spa service
- Style keywords: elegant, professional, soft
- Industry: Beauty/Wellness
- Stack: html-tailwind (default)
Step 2: Generate Design System (REQUIRED)
python3 skills/ui-ux-pro-max/scripts/search.py "beauty spa wellness service elegant" --design-system -p "Serenity Spa"
Output: Complete design system with pattern, style, colors, typography, effects, and anti-patterns.
Step 3: Supplement with Detailed Searches (as needed)
# Get UX guidelines for animation and accessibility
python3 skills/ui-ux-pro-max/scripts/search.py "animation accessibility" --domain ux
# Get alternative typography options if needed
python3 skills/ui-ux-pro-max/scripts/search.py "elegant luxury serif" --domain typography
Step 4: Stack Guidelines
python3 skills/ui-ux-pro-max/scripts/search.py "layout responsive form" --stack html-tailwind
Then: Synthesize design system + detailed searches and implement the design.
Output Formats
The --design-system flag supports two output formats:
# ASCII box (default) - best for terminal display
python3 skills/ui-ux-pro-max/scripts/search.py "fintech crypto" --design-system
# Markdown - best for documentation
python3 skills/ui-ux-pro-max/scripts/search.py "fintech crypto" --design-system -f markdown
Tips for Better Results
- Be specific with keywords - "healthcare SaaS dashboard" > "app"
- Search multiple times - Different keywords reveal different insights
- Combine domains - Style + Typography + Color = Complete design system
- Always check UX - Search "animation", "z-index", "accessibility" for common issues
- Use stack flag - Get implementation-specific best practices
- Iterate - If first search doesn't match, try different keywords
Common Rules for Professional UI
These are frequently overlooked issues that make UI look unprofessional:
Icons & Visual Elements
| Rule |
Do |
Don't |
| No emoji icons |
Use SVG icons (Heroicons, Lucide, Simple Icons) |
Use emojis like 🎨 🚀 ⚙️ 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/hoverable cards |
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) |
Layout & Spacing
| Rule |
Do |
Don't |
| Floating navbar |
Add top-4 left-4 right-4 spacing |
Stick navbar to top-0 left-0 right-0 |
| Content padding |
Account for fixed navbar height |
Let content hide behind fixed elements |
| Consistent max-width |
Use same max-w-6xl or max-w-7xl |
Mix different container widths |
