Searchable design intelligence for building professional UI/UX. Covers 67+ UI styles, 95+ color palettes, 56+ font pairings, 24+ chart types, 29+ landing patterns, and comprehensive UX guidelines.

When to Apply

Use this skill when the task involves UI structure, visual design decisions, interaction patterns, or user experience quality control.

Must Use

• Designing new pages (Landing Page, Dashboard, Admin, SaaS, Mobile App)
• Creating or refactoring UI components (buttons, modals, forms, tables, charts)
• Choosing color schemes, typography systems, spacing, or layout systems
• Reviewing UI code for UX, accessibility, or visual consistency
• Implementing navigation, animations, or responsive behavior
• Making product-level design decisions (style, hierarchy, branding)
• Improving perceived quality, clarity, or usability

Skip

• Pure backend logic
• API or database design only
• Non-UI performance optimization
• Infrastructure or DevOps
• Non-visual scripting or automation

Rule of thumb: If the task changes how something looks, feels, moves, or is interacted with, use this skill.

Tips for Better Design Decisions

Problem	Solution
Can't decide on style/color	Match to product type using Style-Product table above
Dark mode contrast issues	Use desaturated tonal variants; test contrast separately
Animations feel unnatural	Use spring physics; exit 30% faster than enter
Form UX is poor	Inline validation, visible labels, progressive disclosure
Navigation feels confusing	Clear hierarchy, max 5 bottom nav items, predictable back
Layout breaks on small screens	Mobile-first, systematic breakpoints, no horizontal scroll
Performance/jank	Virtualize lists, lazy load, skeleton screens, debounce
UI looks "unprofessional"	Check icon consistency, spacing scale, shadow system, typography
