## How to Use

Search specific domains using the CLI tool below.

---
# Prerequisites

Check if Python is installed:

```bash
python3 --version || python --version
```

If Python is not installed, install it based on user's OS:

**macOS:**
```bash
brew install python3
```

**Ubuntu/Debian:**
```bash
sudo apt update && sudo apt install python3
```

**Windows:**
```powershell
winget install Python.Python.3.12
```

> **Note:** On Windows, use `python` instead of `python3` to run scripts (e.g., `python scripts/search.py` instead of `python3 scripts/search.py`).

---

## How to Use This Skill

Use this skill when the user requests any of the following:

| Scenario | Trigger Examples | Start From |
|----------|-----------------|------------|
| **New project / page** | "做一个 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?"、"推荐配色" | Step 2 (design system) |
| **Review existing UI** | "Review this page for UX issues"、"检查无障碍" | 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)

### Step 2: Generate Design System (REQUIRED)

**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"
```

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

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:**
```
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 2c: Design Dials (optional)

Three optional 1-10 sliders that tune `--design-system` output without changing your query. Add any combination of them to the same command:

```bash
python3 skills/ui-ux-pro-max/scripts/search.py "<query>" --design-system --variance <1-10> --motion <1-10> --density <1-10>
```

| Dial | Low (1-3) | Mid (4-7) | High (8-10) |
|------|-----------|-----------|-------------|
| `--variance` | Centered / minimal (biases toward Minimalism-style categories) | Balanced / modern | Bold / asymmetric (biases toward Brutalism, Bento Grids) |
| `--motion` | Subtle micro-interactions | Standard scroll/stagger motion | Complex choreography (pin, Flip, SplitText) |
| `--density` | Spacious (24-96px spacing scale) | Standard (16-64px, current default) | Dense/dashboard (8-32px spacing scale) |

- `--motion` attaches a ready-to-use GSAP snippet (with framework notes, Do/Don't, and performance notes) pulled from `--domain gsap`, matched to the resolved tier (Subtle/Standard/Complex).
- `--density` overrides the `--space-*` CSS variable table in the ASCII/markdown/MASTER.md output — use it for dashboards (high) vs. marketing pages (low) without hand-editing tokens.
- Leaving a dial unset keeps that part of the output exactly as it was before (no behavior change).

**Example:**
```bash
python3 skills/ui-ux-pro-max/scripts/search.py "internal analytics dashboard" --design-system --variance 8 --motion 7 --density 8 -p "Ops Console"
```

### Step 3: Supplement with Detailed Searches (as needed)

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"` |
| 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"` |

### Step 4: Stack Guidelines

Get implementation-specific best practices for the user's stack:

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

## Example Workflow

**User request:** "Make an AI search homepage。"

### Step 1: Analyze Requirements
- 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

### Step 2: Generate Design System (REQUIRED)

```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.

### Step 3: Supplement with Detailed Searches (as needed)

```bash
# Get style options for a modern tool product
python3 skills/ui-ux-pro-max/scripts/search.py "minimalism dark mode" --domain style

# Get UX best practices for search interaction and loading
python3 skills/ui-ux-pro-max/scripts/search.py "search loading animation" --domain ux
```

### Step 4: Stack Guidelines

```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.

## Output Formats

The `--design-system` flag supports two output formats:

```bash
# 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

### Query Strategy

- 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
- Add `--stack <stack>` for implementation-specific guidance when the target stack is known

### Common Sticking Points

| Problem | What to Do |
|---------|------------|
| 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` |

### Pre-Delivery Checklist

- 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

- 默认图标库使用 **Phosphor (`@phosphor-icons/react`)**。`src/ui-ux-pro-max/data/icons.csv` 中列出的只是常用推荐图标，不是完整集合。
- 当推荐表中找不到合适的图标时：
  - **优先继续从 Phosphor 的完整图标集中选择任何语义更贴切的图标**；
  - 如果 Phosphor 也没有理想选项，可以使用 **Heroicons (`@heroicons/react`)** 作为备选，注意保持风格一致（线性/填充、笔画粗细、圆角风格）。

| Rule | Standard | Avoid | Why It Matters |
|------|----------|--------|----------------|
| **No Emoji as Structural Icons** | Use vector-based icons (e.g., Phosphor `@phosphor-icons/react`, Heroicons `@heroicons/react`, 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 |

### Light/Dark Mode Contrast

| 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 |
