This skill provides comprehensive design guidance for creating exceptional frontend interfaces that are both visually distinctive and cognitively intuitive.

When to Use

Apply these guidelines when:

• Building web components, pages, or applications

• Making UI/UX design decisions

• Designing interaction patterns and information architecture

• Evaluating existing interfaces for improvements

• Ensuring production-grade design quality

Structure

This skill consists of three complementary perspectives:

ui-design.md

Visual design principles focused on aesthetics and brand:

• Typography and color systems

• Motion and micro-interactions

• Spatial composition and layouts

• Anti-patterns to avoid (generic AI aesthetics)

• Creating memorable, distinctive interfaces

ux-design.md

User experience principles based on cognitive psychology and HCI:

• Design Thinking: Mental models, task flows, cognitive budget, context

• Core Principles: Objects not procedures, Modeless, Immediate feedback, Smart defaults, Progressive disclosure, Prevent don't report

• Visual Communication: Signifiers, visual hierarchy, Gestalt grouping, consistency

• UX Psychology: 43 psychology principles with definitions, application strategies, and code examples (organized by category: perception, decision-making, memory, motivation, social influence, patterns)

• Making interfaces feel natural and effortless

Sociomedia's Human Interface Guidelines (100 items):

• Comprehensive interface design principles from basic concepts to accessibility

• Form design, interaction patterns, and visual feedback

• Layout, visual design, and user experience best practices

• Based on extensive research and real-world implementation experience

IMPORTANT: Great design requires all perspectives. Visual beauty without usability is frustrating. Usability without aesthetics is forgettable. Human interface principles provide a comprehensive foundation for both. Use all three documents together for complete design guidance.

Design Philosophy

• Intentionality over intensity: Bold maximalism and refined minimalism both work - the key is executing with precision

• Invisible interface: The best UX feels like no UX at all - users accomplish goals without thinking about the tool

• Context-specific creativity: Avoid generic solutions - design for the specific problem, audience, and constraints

• Cognitive respect: Every element costs mental effort - be ruthless about reducing unnecessary complexity
