Use this skill for design work before/beyond implementation - "desain tampilannya", "bikin konsep UI", "pilih warna/font", brand & visual identity, design system creation, wireframe/mockup concepts, "biar kelihatan profesional/modern", or critiquing visual design. The designer's eye - hierarchy, typography, color, spacing, identity. Do NOT use for implementing states/forms/responsive code (uiux-engineer) or marketing asset copy (marketing-growth).
