| description | UI/UX design production — web (React/Tailwind), game HUD (Phaser/Three.js), tool (CLI). Priority-based categories (1-10), design system workflow, design tokens, pro-rules checklist. |
Khi dùng: Yêu cầu UI/UX → load skill này. Agent tự chọn platform (web/game/tool) dựa trên project type.
Follow priority 1→10; focus on higher priorities first. Each rule applies to all platforms unless marked.
| Pri | Category | Impact | Key Checks | Anti-Patterns |
|---|---|---|---|---|
| 1 | Accessibility | CRITICAL | Contrast ≥4.5:1, Alt text, Keyboard nav, Aria-labels, Focus rings | Removing focus rings, Icon-only without labels, Color-only indicators |
| 2 | Touch & Interaction | CRITICAL | Min 44×44px touch, 8px+ spacing, Loading feedback, Press feedback (80-150ms) | Hover-only, Instant 0ms transitions, No disabled state |
| 3 | Performance | HIGH | WebP/AVIF, Lazy load, Reserve space (CLS<0.1), font-display:swap | Layout thrashing, No image dimensions, FOIT |
| 4 | Layout & Responsive | HIGH | Mobile-first breakpoints, Viewport meta, No horizontal scroll, Safe areas | Fixed px containers, Disable zoom, Content behind notch |
| 5 | Typography & Color | HIGH | Base 16px, Line-height 1.5, Semantic tokens, 8dp spacing rhythm | Text <12px body, Gray-on-gray, Raw hex in components |
| 6 | Style Selection | MEDIUM | Match product type, Consistent style, SVG icons (no emoji) | Mixing flat/skeuomorphic, Emoji as icons, Raster PNGs |
| 7 | Animation | MEDIUM | Duration 150-300ms, Conveys meaning, prefers-reduced-motion | Decorative-only, Animating width/height, No reduced-motion |
| 8 | Forms & Feedback | MEDIUM | Visible labels, Error near field, Helper text, Progressive disclosure | Placeholder-only label, Errors only at top, Overwhelm upfront |
| 9 | Navigation | HIGH | Predictable back, Bottom nav ≤5, Deep linking, Tab order matches visual | Broken back, No deep links, Overloaded nav |
| 10 | Charts & Data | LOW | Legends, Tooltips, Accessible colors, Loading/empty/error states | Color-only meaning, No fallback for missing data |
Define token set before coding components:
// Tailwind convention
colors: { brand: { 50..900 }, surface: { primary, secondary }, text: { primary, secondary, disabled } }
spacing: { xs:4, sm:8, md:16, lg:24, xl:32, 2xl:48 }
fonts: { body: 'Inter, sans-serif', heading: 'Inter, sans-serif', mono: 'JetBrains Mono' }
radius: { sm:4, md:8, lg:12, xl:16 }
For CLI, tokens map to ANSI: colors: { info:cyan, success:green, warning:yellow, error:red, meta:dim }.
NO_COLOR| Dial | Low (1-3) | Mid (4-7) | High (8-10) |
|---|---|---|---|
| Variance | Centered / minimal | Balanced / modern | Bold / asymmetric |
| Motion | Subtle micro-interactions | Standard scroll/stagger | Complex choreography |
| Density | Spacious (24-96px) | Standard (16-64px) | Dense (8-32px) |

| Bug | Root Cause | Fix |
|---|---|---|
| Layout shift | Missing img w/h | w-full h-auto + aspect ratio |
| FOUC | CSS after DOM | Inline critical CSS |
| Dark flash | localStorage race | <script> blocking in <head> |

CLI output format cho hệ thống 4 tầng. Dùng cho mọi agent output.
1. Symbol Set (ASCII, không emoji)
| Ý nghĩa | Symbol | Code |
|---|---|---|
| Success | ✓ | \u2713 |
| Fail | ✗ | \u2717 |
| Running | ⏳ | \u23F3 |
| Arrow | → | \u2192 |
| Box T | ┌──┐ | \u250C\u2500\u2510 |
| Box B | └──┘ | \u2514\u2500\u2518 |
Fallback ($env:NO_COLOR): [>], [x], [ ].
2. Layout — 4 tầng
┌─ T1 ──────────────────────────────────────────┐
│ pxh-help Validate input │
│ → Request {type, target, context} │
└────────────────────────────────────────────────┘
↓
┌─ T2 ──────────────────────────────────────────┐
│ pxh-pm Phase: code→test→fix Retry: 2/3 ⏳ │
└────────────────────────────────────────────────┘
↓
┌─ T3 ──────────────────────────────────────────┐
│ pxh-expert ✓ Code generated ✓ Tests pass │
└────────────────────────────────────────────────┘
↓
┌─ T4 ──────────────────────────────────────────┐
│ pxh-save-history ✓ Session saved │
└────────────────────────────────────────────────┘
Mỗi tầng = 1 box. Prefix [T1], [T2], [T3], [T4].
3. Contract Format
Request {version|type|target|context} → 1 dòng
Task {version|phase|target|skills|workflow} → ≤2 dòng
Result {version|status|artifacts[]} → status + summary
Response {version|status|summary} → 1 dòng cuối
Không in raw JSON — tóm tắt 1-2 dòng.
4. Anti-Patterns
| Anti-pattern | Thay bằng |
|---|---|
| Emoji trong output | ASCII symbols |
| Raw JSON contract | Tóm tắt 1-2 dòng |
| Spam > 10Hz | Update ≤ 5 lần/s |
| Không prefix tầng | [T1], [T2], ... |
| Màu tuỳ tiện | NO_COLOR fallback |
| Excuse | Reality |
|---|---|
| "Sẽ fix responsive sau" | Mobile-first không thể patch sau — thiết kế lại toàn bộ layout |
| "Dark mode là optional" | 30% user dùng dark mode — thiếu là UX fail |
| "Accessibility sau" | WCAG violations = legal risk, phải refactor cả component |
| "CLI màu không cần fallback" | Terminal không màu = output vô dụng |
| "Game UI trên canvas là đủ" | DOM overlay cho UX phức tạp dễ hơn 10x |
| "FOUC không đáng lo" | FOUC = perception app chậm, user thoát ngay |
$env:NO_COLOR = "1" → plain text[Tn] mỗi dòng
