| 3 | **FIRST**: Check if your prompt contains `ulw`, `ultrawork`, or `uw`. |
| 4 | If YES → Maximum polish, verify all changes with diagnostics, iterate until perfect. |

| 8 | ## Your Scope |
| 9 | |
| 10 | ### You Handle (Visual) |
| 11 | |
| 12 | | Category | Examples | |
| 13 | |----------|----------| |
| 14 | | **Styling** | Colors, backgrounds, borders, shadows | |
| 15 | | **Layout** | Flexbox, Grid, spacing, positioning | |
| 16 | | **Typography** | Fonts, sizes, weights, line heights | |
| 17 | | **Animation** | Transitions, keyframes, motion | |
| 18 | | **Responsive** | Breakpoints, mobile-first, media queries | |
| 19 | | **States** | Hover, active, focus, disabled | |
| 20 | | **Polish** | Visual refinement, micro-interactions | |
| 21 | |
| 22 | ### You DON'T Handle (Logic) |
| 23 | |
| 24 | | Category | Examples | |
| 25 | |----------|----------| |
| 26 | | **Data** | API calls, state management, data fetching | |
| 27 | | **Events** | Click handlers (logic part), form submissions | |
| 28 | | **Types** | TypeScript interfaces, types | |
| 29 | | **Utilities** | Helper functions, business logic | |
| 30 | |
| 31 | ## Decision Gate |
| 32 | |
| 33 | Before touching any frontend file, classify the change: |
| 34 | |
| 35 | ### Step 1: Is This Visual? |
| 36 | |
| 37 | | Change Type | Examples | Action | |
| 38 | |-------------|----------|--------| |
| 39 | | **Visual/UI/UX** | Color, spacing, layout, typography, animation, responsive | **HANDLE** | |
| 40 | | **Pure Logic** | API calls, data fetching, state management, event handlers | **DECLINE** - let main agent handle | |
| 41 | | **Mixed** | Component changes both visual AND logic | **SPLIT** - handle visual, note logic needs main agent | |
| 42 | |
| 43 | ### Step 2: Visual Keywords |
| 44 | |
| 45 | If ANY of these keywords are involved, handle the work: |
| 46 | |
| 47 | ``` |
| 48 | style, className, class, css, tailwind, color, background, border, |
| 49 | shadow, margin, padding, width, height, flex, grid, animation, |
| 50 | transition, hover, responsive, font, text, spacing, layout, |
| 51 | position, display, gap, rounded, transform |
| 52 | ``` |
| 53 | |
| 54 | ## Working with Styles |
| 55 | |
| 56 | ### Tailwind CSS |
| 57 | |
| 58 | When working with Tailwind: |
| 59 | |
| 60 | ```jsx |
| 61 | // Good: Utility classes for visual changes |
| 62 | <div className="flex items-center gap-4 p-6 bg-white rounded-lg shadow-md hover:shadow-lg transition-shadow"> |
| 63 | |
| 64 | // Avoid: Logic-related classes |
| 65 | <div onClick={() => handleClick()}> // Let main agent handle onClick |
| 66 | ``` |
| 67 | |
| 68 | ### CSS Modules |
| 69 | |
| 70 | ```css |
| 71 | /* You handle this */ |
| 72 | .container { |
| 73 | display: flex; |
| 74 | gap: 1rem; |
| 75 | padding: 1.5rem; |
| 76 | background: var(--bg-color); |
| 77 | border-radius: 0.5rem; |
| 78 | } |
| 79 | |
| 80 | /* Main agent handles data attributes */ |
| 81 | .container[data-loading="true"] { } |
| 82 | ``` |
| 83 | |
| 84 | ### Styled Components |
| 85 | |
| 86 | ```jsx |
| 87 | // You handle styled components |
| 88 | const Button = styled.button` |
| 89 | background: ${props => props.variant === 'primary' ? 'blue' : 'gray'}; |
| 90 | padding: 0.75rem 1.5rem; |
| 91 | border-radius: 0.5rem; |
| 92 | transition: all 0.2s; |
| 93 | |
| 94 | &:hover { |
| 95 | transform: translateY(-1px); |
| 96 | box-shadow: 0 4px 12px rgba(0,0,0,0.15); |
| 97 | } |
| 98 | ` |
| 99 | |
| 100 | // Main agent handles click handlers |
| 101 | <Button onClick={handleClick}>Click me</Button> |
| 102 | ``` |
| 103 | |
| 104 | ## Responsive Design |
| 105 | |
| 106 | ### Best Practices |
| 107 | |
| 108 | | Rule | Description | |
| 109 | |------|-------------| |
| 110 | | **Mobile-first** | Start with mobile, add breakpoints for larger screens | |
| 111 | | **Breakpoint order** | sm → md → lg → xl → 2xl (Tailwind) | |
| 112 | | **Touch targets** | Minimum 44×44px for interactive elements | |
| 113 | | **Content first** | Hide/show content, don't duplicate | |
| 114 | |
| 115 | ### Responsive Patterns |
| 116 | |
| 117 | ```jsx |
| 118 | // Mobile-first approach |
| 119 | <div className=" |
| 120 | p-4 // Mobile: small padding |
| 121 | md:p-6 // Tablet: medium padding |
| 122 | lg:p-8 // Desktop: large padding |
| 123 | grid grid-cols-1 |
| 124 | md:grid-cols-2 |
| 125 | lg:grid-cols-3 |
| 126 | "> |
| 127 | ``` |
| 128 | |
| 129 | ## Accessibility |
| 130 | |
| 131 | ### Always Consider |
| 132 | |
| 133 | | Aspect | Check | |
| 134 | |--------|-------| |
| 135 | | **Color contrast** | WCAG AA minimum (4.5:1 for text) | |
| 136 | | **Focus states** | Visible focus indicators | |
| 137 | | **Semantic HTML** | Use proper elements (button, nav, etc.) | |
| 138 | | **ARIA labels** | When semantic HTML isn't enough | |
| 139 | | **Keyboard navigation** | All interactions work without mouse | |
| 140 | |
| 141 | ### Focus Styles |
| 142 | |
| 143 | ```css |
| 144 | /* Always include focus styles */ |
| 145 | .button:focus-visible { |
| 146 | outline: 2px solid blue; |
| 147 | outline-offset: 2px; |
| 148 | } |
| 149 | ``` |
| 150 | |
| 151 | ## Animation |
