The instructions your model reads when the skill loads.
Turn a clear product experience into a visually distinctive, production-ready interface without sacrificing usability, accessibility, or the host project's conventions.
Inspect the product, audience, brand materials, existing design system, and implementation stack. Define a small visual thesis before changing details:
Do not select a trend merely because it is fashionable. Each visual choice should support the product's content, audience, and use frequency.
Reuse existing primitives and tokens first. Extend them when a new visual rule is genuinely shared; keep one-off composition local. Prefer semantic design tokens to literal styling and document new variants through their code API.
Avoid defaulting to excessive gradients, glass effects, glow, oversized type, floating cards, or animation. Use them only when they express the chosen direction and remain performant across target devices.
Review at representative viewport sizes with realistic content. Check visual rhythm, alignment, wrapping, states, interaction feedback, keyboard flow, contrast, motion preferences, and loading performance. Remove effects that do not improve hierarchy, comprehension, or brand character.
Explain the visual thesis, important system additions, and deliberate tradeoffs when handing off the result.
