UI/UX Pro Max - Design Intelligence

Comprehensive design guide for web and mobile applications. Contains 67 styles, 96 color palettes, 57 font pairings, 99 UX guidelines, and 25 chart types across 13 technology stacks. Searchable database with priority-based recommendations.

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

Automated Code Audit (run this first for any review task)

scripts/audit.py scans real code files and returns severity-ranked findings with file:line references. It replaces manual checklist reading — the model's job is to interpret output and fix issues, not to mentally check 56 reference files.

# Paths below are relative to the project root (where the user's code lives)

# Scan a single file — all categories, all severities
python skills/ui-ux-pro-max/scripts/audit.py src/checkout.tsx

# Scan an entire directory
python skills/ui-ux-pro-max/scripts/audit.py src/

# Focus on specific category
python skills/ui-ux-pro-max/scripts/audit.py src/ --focus deceptive
python skills/ui-ux-pro-max/scripts/audit.py src/ --focus accessibility
python skills/ui-ux-pro-max/scripts/audit.py src/ --focus humane

# Only show blocking issues
python skills/ui-ux-pro-max/scripts/audit.py src/ --severity critical high

# Grouped summary by violation type — best for large codebases
python skills/ui-ux-pro-max/scripts/audit.py src/ --summary

# JSON output (for programmatic use)
python skills/ui-ux-pro-max/scripts/audit.py src/ --format json

Exit code 1 if any critical findings — safe to use in CI pre-commit hooks.

--summary flag: Groups findings by violation ID instead of per-file detail. Shows top 15 violation types ranked by frequency, and top 10 files by issue count. Use this when scanning large directories — scan first with --summary, then drill into specific violations with regular output.

When to run:

• Any code review, audit, or "check this" request → run audit.py on the files first
• Before delivering UI code → run on all modified files
• When user mentions accessibility, dark patterns, or ethical design → run audit.py, then ethics_check.py

Workflow:

1. Run audit.py → read the output → fix critical/high issues in the actual files
2. For deep guidance on a specific finding, read the Ref: path listed in the finding
3. Reference files are only needed when explaining WHY a finding matters or generating compliant code examples

---

Ethics & Principles Resources

Three reference frameworks in references/. Read index for overview; individual files for deep guidance on a specific finding.

Resource	Index	Individual Files
Laws of UX	references/laws-index.md	references/laws/<name>.md — 30 files
Humane by Design	references/humane-index.md	references/humane/<name>.md — 7 files
Deceptive Design	references/deceptive-index.md	references/deceptive/<name>.md — 16 files

Each individual file contains: summary, code review flags, regulatory context, compliant implementation, metrics.

Design Foundations

Two foundational reference libraries for visual design and motion:

Resource	File	Contents
Elements of Design	references/elements-of-design.md	7 visual elements — line, shape, form, texture, space, color, value — with UI code examples
Principles of Animation	references/principles-of-animation.md	Disney's 12 principles applied to UI motion — easing, timing, squash, anticipation, staging

When to read:

• Designing a new UI from scratch → read elements-of-design.md before choosing styles
• Implementing any animation → read principles-of-animation.md for timing/easing guidance
• Design review mentions "feels flat", "looks cheap", "animation feels wrong" → both files
• User asks about composition, visual hierarchy, motion design, or animation principles → reference these

Ethics Checker — feature-level keyword lookup

Use ethics_check.py when you have a feature description (not code) and need to know which laws/principles/patterns are relevant before designing:

# Which laws/principles/patterns apply to this feature?
python skills/ui-ux-pro-max/scripts/ethics_check.py "checkout flow with subscription upsell"
python skills/ui-ux-pro-max/scripts/ethics_check.py "notification settings" --focus humane
python skills/ui-ux-pro-max/scripts/ethics_check.py "pricing page" --focus deceptive
python skills/ui-ux-pro-max/scripts/ethics_check.py "form design" --focus laws

# Full checklist for all 53 laws/principles/patterns (comprehensive design review)
python skills/ui-ux-pro-max/scripts/ethics_check.py --audit-all

When to use:

• Early design phase (before code exists) → ethics_check.py
• Reviewing existing code → audit.py (faster, file:line findings)
• Comprehensive pre-launch ethics review → --audit-all

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
9	Elements of Design	MEDIUM	design

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 - 100ms (tap), 150ms (tooltip), 200ms (fade/page), 300ms (modal/drawer)
• transform-performance - Use transform/opacity, not width/height/top/left
• loading-states - Skeleton screens or spinners; skeleton matches final layout shape
• easing - ease-out for enter, ease-in for exit, never linear for UI elements
• spring-physics - Use spring for scale/transform (natural feel); duration+easing for opacity
• principles - See references/principles-of-animation.md for Disney's 12 principles applied to UI

Principles quick-ref:

• Slow In/Out: cubic-bezier(0.25, 0, 0, 1) enter · cubic-bezier(0.3, 0, 1, 0.3) exit
• Squash/Stretch: whileTap: {scale: 0.97} · spring overshoot: type: 'spring', stiffness: 300
• Anticipation: hover state (−2px lift) before click; loading pulse before skeleton appears
• Staging: stagger children 50ms · hero enters first, supporting content follows
• Follow Through: exit last item last · momentum continues 1 tick past stop

7. Style Selection (MEDIUM)

• style-match - Match style to product type
• consistency - Use same style across all pages
• no-emoji-icons - Use SVG icons, not emojis

8. Charts & Data (LOW)

• chart-type - Match chart type to data type
• color-guidance - Use accessible color palettes
• data-table - Provide table alternative for accessibility

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

Check for existing design system first: If DESIGN.md exists in the project root, read it before doing anything else. It is the single source of truth — use it instead of generating a new design system. Only run search.py --design-system if no DESIGN.md exists.

Step 2: Generate Design System (REQUIRED if no DESIGN.md exists)

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" --design-system -p "Serenity Spa"

Multiple alternatives — when the first recommendation might not fit, request N options ranked by match score:

python3 skills/ui-ux-pro-max/scripts/search.py "fintech crypto" --design-system --alternatives 3

Each option shows as a separate block with OPTION 1 / 2 / 3 header. Use the first option by default; show alternatives when the user is deciding between directions. --persist always writes option 1.

Step 2b: Persist Design System (DESIGN.md in Project Root)

To write the design system as a persistent file, add --persist:

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

This writes:

• DESIGN.md — single source of truth, placed directly in the project root

With page-specific override:

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

This also writes:

• DESIGN-checkout.md — page-specific overrides alongside DESIGN.md

How to use DESIGN.md:

1. Read DESIGN.md before writing any component — treat every decision as a constraint
2. If a page override exists (DESIGN-checkout.md), its rules take precedence for that page
3. If the user asks to "make it pop" or "add personality", interpret within the design system — don't override it

See references/design-template.md for the full 9-section structure and template.

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, 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

1. Be specific with keywords - "healthcare SaaS dashboard" > "app"
2. Search multiple times - Different keywords reveal different insights
3. Combine domains - Style + Typography + Color = Complete design system
4. Always check UX - Search "animation", "z-index", "accessibility" for common issues
5. Use stack flag - Get implementation-specific best practices
6. 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

---

Additional Scripts

contrast.py — WCAG Contrast Checker

Computes actual contrast ratios using the WCAG relative luminance formula. Fills the gap audit.py cannot cover (CSS variables → actual hex values aren't resolved at parse time).

# Single pair
python skills/ui-ux-pro-max/scripts/contrast.py "#64748B" "#FFFFFF"

# All text/surface pairs from DESIGN.md (recommended before delivery)
python skills/ui-ux-pro-max/scripts/contrast.py DESIGN.md

# All permutations of a list of colors
python skills/ui-ux-pro-max/scripts/contrast.py --list "#0F172A" "#64748B" "#FFFFFF" "#F8FAFC"

Output: ratio, AA/AAA pass/fail for normal and large text. Exit code 1 if any AA failure. Run against DESIGN.md whenever you define or modify the color palette.

---

generate_css_vars.py — Design Token Extractor

Converts DESIGN.md color/typography/spacing decisions into CSS custom properties (:root {}) and optionally a Tailwind extend config.

# Print CSS vars to stdout
python skills/ui-ux-pro-max/scripts/generate_css_vars.py DESIGN.md

# Write to file
python skills/ui-ux-pro-max/scripts/generate_css_vars.py DESIGN.md --out design-tokens.css

# Tailwind extend config instead
python skills/ui-ux-pro-max/scripts/generate_css_vars.py DESIGN.md --tailwind

Token workflow: --design-system --persist → generate_css_vars.py → import tokens into project → validate_tokens.py enforces compliance.

---

validate_tokens.py — Off-System Hex Detector

Scans source files for hex color values not defined in the design system. Catches hardcoded colors that bypass the token system.

# Validate against DESIGN.md tokens
python skills/ui-ux-pro-max/scripts/validate_tokens.py DESIGN.md src/

# Validate against generated CSS vars file
python skills/ui-ux-pro-max/scripts/validate_tokens.py design-tokens.css src/

Output: file:line: #hex not in design system. Exit code 1 if violations found. Run before delivery on all modified UI files.

---

post_write_audit.py — Automatic Audit Hook

Runs audit.py --severity critical high automatically every time Claude writes a UI file. Prints findings immediately so they're caught during generation rather than after.

Setup — add to .claude/settings.json in the project root:

{
  "hooks": {
    "PostToolUse": [{
      "matcher": "Write",
      "hooks": [{
        "type": "command",
        "command": "python /ABSOLUTE/PATH/TO/skills/ui-ux-pro-max/scripts/post_write_audit.py"
      }]
    }]
  }
}

Replace /ABSOLUTE/PATH/TO/ with the actual path to the skill on this machine. The hook reads the Write tool payload from stdin — no arguments needed. Only triggers on .tsx, .jsx, .ts, .js, .vue, .svelte, .css, .html files; silently skips all other file types.

Pre-Delivery Checklist

Before delivering UI code, verify these items:

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
• Use theme colors directly (bg-primary) not var() wrapper

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
• Test both modes before delivery

Layout

• Floating elements have proper spacing from edges
• 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

Ethics & Accessibility (automated — run audit.py on all modified files)

# Run the code auditor on all files being delivered
python skills/ui-ux-pro-max/scripts/audit.py <file_or_directory>

# Critical + high only (fast gate)
python skills/ui-ux-pro-max/scripts/audit.py <file_or_directory> --severity critical high

# For features involving checkout/subscription/notifications — also run topic lookup
python skills/ui-ux-pro-max/scripts/ethics_check.py "<feature description>"

• Zero critical findings required before delivery
• Read the Ref: path on any finding for compliant implementation examples

What audit.py cannot detect (check manually):

• Visual contrast ratios from CSS variables or Tailwind tokens (can't resolve to actual hex values)
• Missing loading / empty / error states (can't detect absence of code)
• Screen reader reading order and announcement logic
• Server-side countdown validation (fake urgency check is client-only)
• Fake social proof in content strings
• role + aria-* completeness on fully custom components
