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.

Rule Categories by Priority#

For human/AI reference: follow priority 1→10 to decide which rule category to focus on first; use --domain <Domain> to query details when needed. Scripts do not read this table.

• motion-meaning - Every animation must express a cause-effect relationship, not just be decorative (Apple HIG)
• state-transition - State changes (hover / active / expanded / collapsed / modal) should animate smoothly, not snap
• continuity - Page/screen transitions should maintain spatial continuity (shared element, directional slide) (Apple HIG)
• parallax-subtle - Use parallax sparingly; must respect reduced-motion and not cause disorientation (Apple HIG)
• spring-physics - Prefer spring/physics-based curves over linear or cubic-bezier for natural feel (Apple HIG fluid animations)
• exit-faster-than-enter - Exit animations shorter than enter (~60–70% of enter duration) to feel responsive (MD motion)

• shared-element-transition - Use shared element / hero transitions for visual continuity between screens (MD, HIG)
• interruptible - Animations must be interruptible; user tap/gesture cancels in-progress animation immediately (Apple HIG)
• no-blocking-animation - Never block user input during an animation; UI must stay interactive (Apple HIG)
• fade-crossfade - Use crossfade for content replacement within the same container (MD)
• scale-feedback - Subtle scale (0.95–1.05) on press for tappable cards/buttons; restore on release (HIG, MD)
• gesture-feedback - Drag, swipe, and pinch must provide real-time visual response tracking the finger (MD Motion)
• hierarchy-motion - Use translate/scale direction to express hierarchy: enter from below = deeper, exit upward = back (MD)
• motion-consistency - Unify duration/easing tokens globally; all animations share the same rhythm and feel
• opacity-threshold - Fading elements should not linger below opacity 0.2; either fade fully or remain visible
• modal-motion - Modals/sheets should animate from their trigger source (scale+fade or slide-in) for spatial context (HIG, MD)
• navigation-direction - Forward navigation animates left/up; backward animates right/down — keep direction logically consistent (HIG)

9. Navigation Patterns (HIGH)#

• bottom-nav-limit - Bottom navigation max 5 items; use labels with icons (Material Design)
• drawer-usage - Use drawer/sidebar for secondary navigation, not primary actions (Material Design)
• back-behavior - Back navigation must be predictable and consistent; preserve scroll/state (Apple HIG, MD)
• deep-linking - All key screens must be reachable via deep link / URL for sharing and notifications (Apple HIG, MD)
• tab-bar-ios - iOS: use bottom Tab Bar for top-level navigation (Apple HIG)
• top-app-bar-android - Android: use Top App Bar with navigation icon for primary structure (Material Design)
• nav-label-icon - Navigation items must have both icon and text label; icon-only nav harms discoverability (MD)

• state-preservation - Navigating back must restore previous scroll position, filter state, and input (HIG, MD)
• gesture-nav-support - Support system gesture navigation (iOS swipe-back, Android predictive back) without conflict (HIG, MD)
• tab-badge - Use badges on nav items sparingly to indicate unread/pending; clear after user visits (HIG, MD)
• overflow-menu - When actions exceed available space, use overflow/more menu instead of cramming (MD)
• 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
• modal-vs-navigation - Modals must not be used for primary navigation flows; they break the user's path (HIG)
• focus-on-route-change - After page transition, move focus to main content region for screen reader users (WCAG)
• persistent-nav - Core navigation must remain reachable from deep pages; don't hide it entirely in sub-flows (HIG, MD)
• destructive-nav-separation - Dangerous actions (delete account, logout) must be visually and spatially separated from normal nav items (HIG, MD)
• empty-nav-state - When a nav destination is unavailable, explain why instead of silently hiding it (MD)

10. Charts & Data (LOW)#

• chart-type - Match chart type to data type (trend → line, comparison → bar, proportion → pie/donut)
• color-guidance - Use accessible color palettes; avoid red/green only pairs for colorblind users (WCAG, MD)
• data-table - Provide table alternative for accessibility; charts alone are not screen-reader friendly (WCAG)
• pattern-texture - Supplement color with patterns, textures, or shapes so data is distinguishable without color (WCAG, MD)
• legend-visible - Always show legend; position near the chart, not detached below a scroll fold (MD)
• tooltip-on-interact - Provide tooltips/data labels on hover (Web) or tap (mobile) showing exact values (HIG, MD)
• axis-labels - Label axes with units and readable scale; avoid truncated or rotated labels on mobile
• responsive-chart - Charts must reflow or simplify on small screens (e.g. horizontal bar instead of vertical, fewer ticks)
• empty-data-state - Show meaningful empty state when no data exists ("No data yet" + guidance), not a blank chart (MD)
• loading-chart - Use skeleton or shimmer placeholder while chart data loads; don't show an empty axis frame
• animation-optional - Chart entrance animations must respect prefers-reduced-motion; data should be readable immediately (HIG)
• large-dataset - For 1000+ data points, aggregate or sample; provide drill-down for detail instead of rendering all (MD)
• number-formatting - Use locale-aware formatting for numbers, dates, currencies on axes and labels (HIG, MD)
• touch-target-chart - Interactive chart elements (points, segments) must have ≥44pt tap area or expand on touch (Apple HIG)
• no-pie-overuse - Avoid pie/donut for >5 categories; switch to bar chart for clarity
• contrast-data - Data lines/bars vs background ≥3:1; data text labels ≥4.5:1 (WCAG)
• legend-interactive - Legends should be clickable to toggle series visibility (MD)
• direct-labeling - For small datasets, label values directly on the chart to reduce eye travel
• tooltip-keyboard - Tooltip content must be keyboard-reachable and not rely on hover alone (WCAG)
• sortable-table - Data tables must support sorting with aria-sort indicating current sort state (WCAG)
• axis-readability - Axis ticks must not be cramped; maintain readable spacing, auto-skip on small screens
• data-density - Limit information density per chart to avoid cognitive overload; split into multiple charts if needed
• trend-emphasis - Emphasize data trends over decoration; avoid heavy gradients/shadows that obscure the data
• gridline-subtle - Grid lines should be low-contrast (e.g. gray-200) so they don't compete with data
• focusable-elements - Interactive chart elements (points, bars, slices) must be keyboard-navigable (WCAG)
• screen-reader-summary - Provide a text summary or aria-label describing the chart's key insight for screen readers (WCAG)
• error-state-chart - Data load failure must show error message with retry action, not a broken/empty chart
• export-option - For data-heavy products, offer CSV/image export of chart data
• drill-down-consistency - Drill-down interactions must maintain a clear back-path and hierarchy breadcrumb
• time-scale-clarity - Time series charts must clearly label time granularity (day/week/month) and allow switching

How to Use This Skill#

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

ScenarioTrigger ExamplesStart FromNew 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 aboveFix a UI bug"Button hover is broken", "Layout shifts on load"Quick Reference → relevant sectionImprove / 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:

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...

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:

NeedDomainExampleProduct type patternsproduct``--domain product "entertainment social"More style optionsstyle``--domain style "glassmorphism dark"Color palettescolor``--domain color "entertainment vibrant"Font pairingstypography``--domain typography "playful modern"Chart recommendationschart``--domain chart "real-time dashboard"UX best practicesux``--domain ux "animation accessibility"Alternative fontstypography``--domain typography "elegant luxury"Individual Google Fontsgoogle-fonts``--domain google-fonts "sans serif popular variable"Landing structurelanding``--domain landing "hero social-proof"React Native perfreact``--domain react "rerender memo list"App interface a11yweb``--domain web "accessibilityLabel touch safe-areas"AI prompt / CSS keywordsprompt``--domain prompt "minimalism"

Step 4: Stack Guidelines (React Native)#

Get React Native implementation-specific best practices:

bash

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

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
• Always add --stack react-native for implementation-specific guidance

Common Sticking Points#

ProblemWhat to DoCan't decide on style/colorRe-run --design-system with different keywordsDark mode contrast issuesQuick Reference §6: color-dark-mode + color-accessible-pairsAnimations feel unnaturalQuick Reference §7: spring-physics + easing + exit-faster-than-enterForm UX is poorQuick Reference §8: inline-validation + error-clarity + focus-managementNavigation feels confusingQuick Reference §9: nav-hierarchy + bottom-nav-limit + back-behaviorLayout breaks on small screensQuick Reference §5: mobile-first + breakpoint-consistencyPerformance / jankQuick 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#

RuleStandardAvoidWhy It MattersNo Emoji as Structural IconsUse 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 AssetsUse 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 StatesUse 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 LogosUse 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 SizingDefine 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 ConsistencyUse 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 DisciplineUse one icon style per hierarchy level.Mixing filled and outline icons at the same hierarchy level.Maintains semantic clarity and stylistic coherence.Touch Target MinimumMinimum 44×44pt interactive area (use hitSlop if icon is smaller).Small icons without expanded tap area.Meets accessibility and platform usability standards.Icon AlignmentAlign icons to text baseline and maintain consistent padding.Misaligned icons or inconsistent spacing around them.Prevents subtle visual imbalance that reduces perceived quality.Icon ContrastFollow 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)#

RuleDoDon'tTap feedbackProvide clear pressed feedback (ripple/opacity/elevation) within 80-150msNo visual response on tapAnimation timingKeep micro-interactions around 150-300ms with platform-native easingInstant transitions or slow animations (>500ms)Accessibility focusEnsure screen reader focus order matches visual order and labels are descriptiveUnlabeled controls or confusing focus traversalDisabled state clarityUse disabled semantics ( disabled/native disabled props), reduced emphasis, and no tap actionControls that look tappable but do nothingTouch target minimumKeep tap areas >=44x44pt (iOS) or >=48x48dp (Android), expand hit area when icon is smallerTiny tap targets or icon-only hit areas without paddingGesture conflict preventionKeep one primary gesture per region and avoid nested tap/drag conflictsOverlapping gestures causing accidental actionsSemantic native controlsPrefer native interactive primitives ( Button, Pressable, platform equivalents) with proper accessibility rolesGeneric containers used as primary controls without semantics

Light/Dark Mode Contrast#

RuleDoDon'tSurface readability (light)Keep cards/surfaces clearly separated from background with sufficient opacity/elevationOverly transparent surfaces that blur hierarchyText contrast (light)Maintain body text contrast >=4.5:1 against light surfacesLow-contrast gray body textText contrast (dark)Maintain primary text contrast >=4.5:1 and secondary text >=3:1 on dark surfacesDark mode text that blends into backgroundBorder and divider visibilityEnsure separators are visible in both themes (not just light mode)Theme-specific borders disappearing in one modeState contrast parityKeep pressed/focused/disabled states equally distinguishable in light and dark themesDefining interaction states for one theme onlyToken-driven themingUse semantic color tokens mapped per theme across app surfaces/text/iconsHardcoded per-screen hex valuesScrim and modal legibilityUse a modal scrim strong enough to isolate foreground content (typically 40-60% black)Weak scrim that leaves background visually competing

Layout & Spacing#

RuleDoDon'tSafe-area complianceRespect top/bottom safe areas for all fixed headers, tab bars, and CTA barsPlacing fixed UI under notch, status bar, or gesture areaSystem bar clearanceAdd spacing for status/navigation bars and gesture home indicatorLet tappable content collide with OS chromeConsistent content widthKeep predictable content width per device class (phone/tablet)Mixing arbitrary widths between screens8dp spacing rhythmUse a consistent 4/8dp spacing system for padding/gaps/section spacingRandom spacing increments with no rhythmReadable text measureKeep long-form text readable on large devices (avoid edge-to-edge paragraphs on tablets)Full-width long text that hurts readabilitySection spacing hierarchyDefine clear vertical rhythm tiers (e.g., 16/24/32/48) by hierarchySimilar UI levels with inconsistent spacingAdaptive gutters by breakpointIncrease horizontal insets on larger widths and in landscapeSame narrow gutter on all device sizes/orientationsScroll and fixed element coexistenceAdd bottom/top content insets so lists are not hidden behind fixed barsScroll content obscured by sticky headers/footers

Pre-Delivery Checklist#

Before delivering UI code, verify these items: Scope notice: This checklist is for App UI (iOS/Android/React Native/Flutter).

Visual Quality#

• No emojis used as icons (use SVG instead)
• All icons come from a consistent icon family and style
• Official brand assets are used with correct proportions and clear space
• Pressed-state visuals do not shift layout bounds or cause jitter
• Semantic theme tokens are used consistently (no ad-hoc per-screen hardcoded colors)

Interaction#

• All tappable elements provide clear pressed feedback (ripple/opacity/elevation)
• Touch targets meet minimum size (>=44x44pt iOS, >=48x48dp Android)
• Micro-interaction timing stays in the 150-300ms range with native-feeling easing
• Disabled states are visually clear and non-interactive
• Screen reader focus order matches visual order, and interactive labels are descriptive
• Gesture regions avoid nested/conflicting interactions (tap/drag/back-swipe conflicts)

Light/Dark Mode#

• Primary text contrast >=4.5:1 in both light and dark mode
• Secondary text contrast >=3:1 in both light and dark mode
• Dividers/borders and interaction states are distinguishable in both modes
• Modal/drawer scrim opacity is strong enough to preserve foreground legibility (typically 40-60% black)
• Both themes are tested before delivery (not inferred from a single theme)

Layout#

• Safe areas are respected for headers, tab bars, and bottom CTA bars
• Scroll content is not hidden behind fixed/sticky bars
• Verified on small phone, large phone, and tablet (portrait + landscape)
• Horizontal insets/gutters adapt correctly by device size and orientation
• 4/8dp spacing rhythm is maintained across component, section, and page levels
• Long-form text measure remains readable on larger devices (no edge-to-edge paragraphs)

Accessibility#

• All meaningful images/icons have accessibility labels
• Form fields have labels, hints, and clear error messages
• Color is not the only indicator
• Reduced motion and dynamic text size are supported without layout breakage
• Accessibility traits/roles/states (selected, disabled, expanded) are announced correctly
