# UI/UX Pro Max - Design Intelligence

Comprehensive design guide for web and mobile applications. Contains 50+ styles, 161 color palettes, 57 font pairings, 161 product types with reasoning rules, 99 UX guidelines, and 25 chart types across 10 technology stacks. Searchable database with priority-based recommendations.

## 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.

- `bottom-nav-top-level` - Bottom nav is for top-level screens only; never nest sub-navigation inside it (MD)
- `adaptive-navigation` - Large screens (≥1024px) prefer sidebar; small screens use bottom/top nav (Material Adaptive)
- `back-stack-integrity` - Never silently reset the navigation stack or unexpectedly jump to home (HIG, MD)
- `navigation-consistency` - Navigation placement must stay the same across all pages; don't change by page type
- `avoid-mixed-patterns` - Don't mix Tab + Sidebar + Bottom Nav at the same hierarchy level

## 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
```

## 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**: read it from the project, do not assume one. This line said
  "React Native (this project's only tech stack)" — inherited from the project
  this skill was vendored from, not true here. `data/stacks/` carries sixteen;
  pick the one the project actually uses.

### 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/[pag...
