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

• 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

Skip

• 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
