When to Apply
This Skill should be used when the task involves UI structure, visual design decisions, interaction patterns, or user experience quality control.
Must Use
This Skill must be invoked in the following situations:
- Designing new pages (Landing Page, Dashboard, Admin, SaaS, Mobile App)
- Creating or refactoring UI components (buttons, modals, forms, tables, charts, etc.)
- Choosing color schemes, typography systems, spacing standards, or layout systems
- Reviewing UI code for user experience, accessibility, or visual consistency
- Implementing navigation structures, animations, or responsive behavior
- Making product-level design decisions (style, information hierarchy, brand expression)
- Improving perceived quality, clarity, or usability of interfaces
Recommended
This Skill is recommended in the following situations:
- UI looks "not professional enough" but the reason is unclear
- Receiving feedback on usability or experience
- Pre-launch UI quality optimization
- Aligning cross-platform design (Web / iOS / Android)
- Building design systems or reusable component libraries
Skip
This Skill is not needed in the following situations:
- Pure backend logic development
- Only involving API or database design
- Performance optimization unrelated to the interface
- Infrastructure or DevOps work
- Non-visual scripts or automation tasks
Decision criteria: If the task will change how a feature looks, feels, moves, or is interacted with, this Skill should be used.

## How to Use This Skill
Use this skill when the user requests any of the following:
| Scenario | Trigger Examples | Start From |
|----------|-----------------|------------|
| **New project / page** | "Build a landing page", "Build a dashboard" | Step 1 → Step 2 (design system) |
| **New component** | "Create a pricing card", "Add a modal" | Step 3 (domain search: style, ux) |
| **Choose style / color / font** | "What style fits a fintech app?", "Recommend a color palette" | Step 2 (design system) |
| **Review existing UI** | "Review this page for UX issues", "Check accessibility" | Quick Reference checklist above |
| **Fix a UI bug** | "Button hover is broken", "Layout shifts on load" | Quick Reference → relevant section |
| **Improve / optimize** | "Make this faster", "Improve mobile experience" | Step 3 (domain search: ux, react) |
| **Implement dark mode** | "Add dark mode support" | Step 3 (domain: style "dark mode") |
| **Add charts / data viz** | "Add an analytics dashboard chart" | Step 3 (domain: chart) |
| **Stack best practices** | "React performance tips"、"SwiftUI navigation" | Step 4 (stack search) |
Follow this workflow:
### Step 1: Analyze User Requirements
Extract key information from user request:
- **Product type**: Entertainment (social, video, music, gaming), Tool (scanner, editor, converter), Productivity (task manager, notes, calendar), or hybrid
- **Target audience**: C-end consumer users; consider age group, usage context (commute, leisure, work)
- **Style keywords**: playful, vibrant, minimal, dark mode, content-first, immersive, etc.
- **Stack**: React Native (this project's only tech stack)
**Always start with `--design-system`** to get comprehensive recommendations with reasoning:
```bash
python3 skills/ui-ux-pro-max/scripts/search.py "<product_type> <industry> <keywords>" --design-system [-p "Project Name"]
This command:
1. Searches 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:**
```bash
python3 skills/ui-ux-pro-max/scripts/search.py "beauty spa wellness service" --design-system -p "Serenity Spa"
To save the design system for **hierarchical retrieval across sessions**, add `--persist`:
```bash
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:**
```bash
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:**
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
**Context-aware retrieval prompt:**
```text
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...
After getting the design system, use domain searches to get additional details:
```bash
python3 skills/ui-ux-pro-max/scripts/search.py "<keyword>" --domain <domain> [-n <max_results>]
**When to use detailed searches:**
| Need | Domain | Example |
|------|--------|---------|
| Product type patterns | `product` | `--domain product "entertainment social"` |
| More style options | `style` | `--domain style "glassmorphism dark"` |
| Color palettes | `color` | `--domain color "entertainment vibrant"` |
| Font pairings | `typography` | `--domain typography "playful modern"` |
| Chart recommendations | `chart` | `--domain chart "real-time dashboard"` |
| UX best practices | `ux` | `--domain ux "animation accessibility"` |
| Alternative fonts | `typography` | `--domain typography "elegant luxury"` |
| Individual Google Fonts | `google-fonts` | `--domain google-fonts "sans serif popular variable"` |
| Landing structure | `landing` | `--domain landing "hero social-proof"` |
| React Native perf | `react` | `--domain react "rerender memo list"` |
| App interface a11y | `web` | `--domain web "accessibilityLabel touch safe-areas"` |
| AI prompt / CSS keywords | `prompt` | `--domain prompt "minimalism"` |
Get React Native implementation-specific best practices:
```bash
python3 skills/ui-ux-pro-max/scripts/search.py "<keyword>" --stack react-native
---
| Domain | Use For | Example Keywords |
|--------|---------|------------------|
| `product` | Product type recommendations | SaaS, e-commerce, portfolio, healthcare, beauty, service |
| `style` | UI styles, colors, effects | glassmorphism, minimalism, dark mode, brutalism |
| `typography` | Font pairings, Google Fonts | elegant, playful, professional, modern |
| `color` | Color palettes by product type | saas, ecommerce, healthcare, beauty, fintech, service |
| `landing` | Page structure, CTA strategies | hero, hero-centric, testimonial, pricing, social-proof |
| `chart` | Chart types, library recommendations | trend, comparison, timeline, funnel, pie |
| `ux` | Best practices, anti-patterns | animation, accessibility, z-index, loading |
| `google-fonts` | Individual Google Fonts lookup | sans serif, monospace, japanese, variable font, popular |
| `react` | React/Next.js performance | waterfall, bundle, suspense, memo, rerender, cache |
| `web` | App interface guidelines (iOS/Android/React Native) | accessibilityLabel, touch targets, safe areas, Dynamic Type |
| `prompt` | AI prompts, CSS keywords | (style name) |
| Stack | Focus |
|-------|-------|
| `react-native` | Components, Navigation, Lists |

**User request:** "Make an AI search homepage."
- Product type: Tool (AI search engine)
- Target audience: C-end users looking for fast, intelligent search
- Style keywords: modern, minimal, content-first, dark mode
- Stack: React Native
```bash
python3 skills/ui-ux-pro-max/scripts/search.py "AI search tool modern minimal" --design-system -p "AI Search"
**Output:** Complete design system with pattern, style, colors, typography, effects, and anti-patterns.
```bash
python3 skills/ui-ux-pro-max/scripts/search.py "minimalism dark mode" --domain style
python3 skills/ui-ux-pro-max/scripts/search.py "search loading animation" --domain ux
```bash
python3 skills/ui-ux-pro-max/scripts/search.py "list performance navigation" --stack react-native
**Then:** Synthesize design system + detailed searches and implement the design.
---
The `--design-system` flag supports two output formats:
```bash
python3 skills/ui-ux-pro-max/scripts/search.py "fintech crypto" --design-system
python3 skills/ui-ux-pro-max/scripts/search.py "fintech crypto" --design-system -f markdown
---
- Use **multi-dimensional keywords** — combine product + industry + tone + density: `"entertainment social vibrant content-dense"` not just `"app"`
- Try different keywords for the same need: `"playful neon"` → `"vibrant dark"` → `"content-first minimal"`
- Use `--design-system` first for full recommendations, then `--domain` to deep-dive any dimension you're unsure about
- Always add `--stack react-native` for implementation-specific guidance

| Can't decide on style/color | Re-run `--design-system` with different keywords |
| Dark mode contrast issues | Quick Reference §6: `color-dark-mode` + `color-accessible-pairs` |
| Animations feel unnatural | Quick Reference §7: `spring-physics` + `easing` + `exit-faster-than-enter` |
| Form UX is poor | Quick Reference §8: `inline-validation` + `error-clarity` + `focus-management` |
| Navigation feels confusing | Quick Reference §9: `nav-hierarchy` + `bottom-nav-limit` + `back-behavior` |
| Layout breaks on small screens | Quick Reference §5: `mobile-first` + `breakpoint-consistency` |
| Performance / jank | Quick Reference §3: `virtualize-lists` + `main-thread-budget` + `debounce-throttle` |
- Run `--domain ux "animation accessibility z-index loading"` as a UX validation pass before implementation
- Run through Quick Reference **§1–§3** (CRITICAL + HIGH) as a final review
- Test on 375px (small phone) and landscape orientation
- Verify behavior with **reduced-motion** enabled and **Dynamic Type** at largest size
- Check dark mode contrast independently (don't assume light mode values work)
- Confirm all touch targets ≥44pt and no content hidden behind safe areas

## Common Rules for Professional UI
These are frequently overlooked issues that make UI look unprofessional:
Scope notice: The rules below are for App UI (iOS/Android/React Native/Flutter), not desktop-web interaction patterns.
### Icons & Visual Elements
| Rule | Standard | Avoid | Why It Matters |
|------|----------|--------|----------------|
| **No Emoji as Structural Icons** | Use vector-based icons (e.g., Lucide, react-native-vector-icons, @expo/vector-icons). | Using emojis (🎨 🚀 ⚙️) for navigation, settings, or system controls. | Emojis are font-dependent, inconsistent across platforms, and cannot be controlled via design tokens. |
| **Vector-Only Assets** | Use SVG or platform vector icons that scale cleanly and support theming. | Raster PNG icons that blur or pixelate. | Ensures scalability, crisp rendering, and dark/light mode adaptability. |
| **Stable Interaction States** | Use color, opacity, or elevation transitions for press states without changing layout bounds. | Layout-shifting transforms that move surrounding content or trigger visual jitter. | Prevents unstable interactions and preserves smooth motion/perceived quality on mobile. |
| **Correct Brand Logos** | Use official brand assets and follow their usage guidelines (spacing, color, clear space). | Guessing logo paths, recoloring unofficially, or modifying proportions. | Prevents brand misuse and ensures legal/platform compliance. |
| **Consistent Icon Sizing** | Define icon sizes as design tokens (e.g., icon-sm, icon-md = 24pt, icon-lg). | Mixing arbitrary values like 20pt / 24pt / 28pt randomly. | Maintains rhythm and visual hierarchy across the interface. |
| **Stroke Consistency** | Use a consistent stroke width within the same visual layer (e.g., 1.5px or 2px). | Mixing thick and thin stroke styles arbitrarily. | Inconsistent strokes reduce perceived polish and cohesion. |
| **Filled vs Outline Discipline** | Use one icon style per hierarchy level. | Mixing filled and outline icons at the same hierarchy level. | Maintains semantic clarity and stylistic coherence. |
| **Touch Target Minimum** | Minimum 44×44pt interactive area (use hitSlop if icon is smaller). | Small icons without expanded tap area. | Meets accessibility and platform usability standards. |
| **Icon Alignment** | Align icons to text baseline and maintain consistent padding. | Misaligned icons or inconsistent spacing around them. | Prevents subtle visual imbalance that reduces perceived quality. |
| **Icon Contrast** | Follow WCAG contrast standards: 4.5:1 for small elements, 3:1 minimum for larger UI glyphs. | Low-contrast icons that blend into the background. | Ensures accessibility in both light and dark modes. |
### Interaction (App)
| Rule | Do | Don't |
|------|----|----- |
| **Tap feedback** | Provide clear pressed feedback (ripple/opacity/elevation) within 80-150ms | No visual response on tap |
| **Animation timing** | Keep micro-interactions around 150-300ms with platform-native easing | Instant transitions or slow animations (>500ms) |
| **Accessibility focus** | Ensure screen reader focus order matches visual order and labels are descriptive | Unlabeled controls or confusing focus traversal |
| **Disabled state clarity** | Use disabled semantics (`disabled`/native disabled props), reduced emphasis, and no tap action | Controls that look tappable but do nothing |
| **Touch target minimum** | Keep tap areas >=44x44pt (iOS) or >=48x48dp (Android), expand hit area when icon is smaller | Tiny tap targets or icon-only hit areas without padding |
| **Gesture conflict prevention** | Keep one primary gesture per region and avoid nested tap/drag conflicts | Overlapping gestures causing accidental actions |
| **Semantic native controls** | Prefer native interactive primitives (`Button`, `Pressable`, platform equivalents) with proper accessibility roles | Generic containers used as primary controls without semantics |
| Rule | Do | Don't |
|------|----|----- |
| **Surface readability (light)** | Keep cards/surfaces clearly separated from background with sufficient opacity/elevation | Overly transparent surfaces that blur hierarchy |
| **Text contrast (light)** | Maintain body text contrast >=4.5:1 against light surfaces | Low-contrast gray body text |
| **Text contrast (dark)** | Maintain primary text contrast >=4.5:1 and secondary text >=3:1 on dark surfaces | Dark mode text that blends into background |
| **Border and divider visibility** | Ensure separators are visible in both themes (not just light mode) | Theme-specific borders disappearing in one mode |
| **State contrast parity** | Keep pressed/focused/disabled states equally distinguishable in light and dark themes | Defining interaction states for one theme only |
| **Token-driven theming** | Use semantic color tokens mapped per theme across app surfaces/text/icons | Hardcoded per-screen hex values |
| **Scrim and modal legibility** | Use a modal scrim strong enough to isolate foreground content (typically 40-60% black) | Weak scrim that leaves background visually competing |
### Layout & Spacing
| Rule | Do | Don't |
|------|----|----- |
| **Safe-area compliance** | Respect top/bottom safe areas for all fixed headers, tab bars, and CTA bars | Placing fixed UI under notch, status bar, or gesture area |
| **System bar clearance** | Add spacing for status/navigation bars and gesture home indicator | Let tappable content collide with OS chrome |
| **Consistent content width** | Keep predictable content width per device class (phone/tablet) | Mixing arbitrary widths between screens |
| **8dp spacing rhythm** | Use a consistent 4/8dp spacing system for padding/gaps/section spacing | Random spacing increments with no rhythm |
| **Readable text measure** | Keep long-form text readable on large devices (avoid edge-to-edge paragraphs on tablets) | Full-width long text that hurts readability |
| **Section spacing hierarchy** | Define clear vertical rhythm tiers (e.g., 16/24/32/48) by hierarchy | Similar UI levels with inconsistent spacing |
| **Adaptive gutters by breakpoint** | Increase horizontal insets on larger widths and in landscape | Same narrow gutter on all device sizes/orientations |
| **Scroll and fixed element coexistence** | Add bottom/top content insets so lists are not hidden behind fixed bars | Scroll content obscured by sticky headers/footers |
