About

frontend-design is a vercel-labs/agent-eval skill (Apache License 2.0) that guides coding agents to produce, review, and refine frontend UI designs with structured evaluation loops. Instead of one-shot component output, the skill drives critique-and-iterate cycles on layout, hierarchy, and visual distinctiveness so interfaces avoid generic AI aesthetics. Developers reach for frontend-design when scaffolding marketing pages, dashboards, or component libraries where taste, spacing, typography, and hierarchy matter as much as correctness. The eval-oriented packaging from agent-eval signals measurable design quality gates agents run before accepting a UI proposal.

  • Structured evaluation of visual hierarchy, spacing, typography and component consistency
  • Parallel critique runs that compare multiple design variants side-by-side
  • Automated scoring against 12 core frontend design principles
  • Generates concrete improvement recommendations with code examples
  • Hard-gate: requires approved visual spec before proceeding to implementation

How do you iterate on distinctive frontend UI designs with agents?

Generate, critique, and iterate on frontend UI designs and component hierarchies using structured evaluation loops.

Who is it for?

Frontend developers who want agent-generated interfaces critiqued and refined through evaluation loops instead of accepting first-pass generic UI output.

Skip if: Developers who only need backend API work, design-system token migration, or accessibility audits without generative UI design iteration.

When should I use this skill?

The user asks to design, critique, or iterate on frontend UI, component hierarchies, or distinctive page layouts with evaluation feedback.

What you get

Critiqued UI layouts, component hierarchies, and refined frontend designs passed through structured evaluation loops.

  • UI layouts
  • component hierarchies
  • design critique notes

This skill guides creation of distinctive, production-grade frontend interfaces that avoid generic "AI slop" aesthetics. Implement real working code with exceptional attention to aesthetic details and creative choices.

The user provides frontend requirements: a component, page, application, or interface to build. They may include context about the purpose, audience, or technical constraints.

Design Thinking

Before coding, understand the context and commit to a BOLD aesthetic direction:

  • Purpose: What problem does this interface solve? Who uses it?
  • Tone: Pick an extreme: brutally minimal, maximalist chaos, retro-futuristic, organic/natural, luxury/refined, playful/toy-like, editorial/magazine, brutalist/raw, art deco/geometric, soft/pastel, industrial/utilitarian, etc. There are so many flavors to choose from. Use these for inspiration but design one that is true to the aesthetic direction.
  • Constraints: Technical requirements (framework, performance, accessibility).
  • Differentiation: What makes this UNFORGETTABLE? What's the one thing someone will remember?

CRITICAL: Choose a clear conceptual direction and execute it with precision. Bold maximalism and refined minimalism both work - the key is intentionality, not intensity.

Then implement working code (HTML/CSS/JS, React, Vue, etc.) that is:

  • Production-grade and functional
  • Visually striking and memorable
  • Cohesive with a clear aesthetic point-of-view
  • Meticulously refined in every detail

Frontend Aesthetics Guidelines

Focus on:

  • Typography: Choose fonts that are beautiful, unique, and interesting. Avoid generic fonts like Arial and Inter; opt instead for distinctive choices that elevate the frontend's aesthetics; unexpected, characterful font choices. Pair a distinctive display font with a refined body font.
  • Color & Theme: Commit to a cohesive aesthetic. Use CSS variables for consistency. Dominant colors with sharp accents outperform timid, evenly-distributed palettes.
  • Motion: Use animations for effects and micro-interactions. Prioritize CSS-only solutions for HTML. Use Motion library for React when available. Focus on high-impact moments: one well-orchestrated page load with staggered reveals (animation-delay) creates more delight than scattered micro-interactions. Use scroll-triggering and hover states that surprise.
  • Spatial Composition: Unexpected layouts. Asymmetry. Overlap. Diagonal flow. Grid-breaking elements. Generous negative space OR controlled density.
  • Backgrounds & Visual Details: Create atmosphere and depth rather than defaulting to solid colors. Add contextual effects and textures that match the overall aesthetic. Apply creative forms like gradient meshes, noise textures, geometric patterns, layered transparencies, dramatic shadows, decorative borders, custom cursors, and grain overlays.

NEVER use generic AI-generated aesthetics like overused font families (Inter, Roboto, Arial, system fonts), cliched color schemes (particularly purple gradients on white backgrounds), predictable layouts and component patterns, and cookie-cutter design that lacks context-specific character.

Interpret creatively and make unexpected choices that feel genuinely designed for the context. No design should be the same. Vary between light and dark themes, different fonts, different aesthetics. NEVER converge on common choices (Space Grotesk, for example) across generations.

IMPORTANT: Match implementation complexity to the aesthetic vision. Maximalist designs need elaborate code with extensive animations and effects. Minimalist or refined designs need restraint, precision, and careful attention to spacing, typography, and subtle details. Elegance comes from executing the vision well.

Remember: Claude is capable of extraordinary creative work. Don't hold back, show what can truly be created when thinking outside the box and committing fully to a distinctive vision.

FAQ

What does vercel-labs frontend-design skill do?

The vercel-labs/agent-eval frontend-design skill generates, critiques, and iterates frontend UI designs and component hierarchies through structured evaluation loops. Developers use it to avoid generic first-pass agent interfaces.

How is frontend-design different from one-shot UI generation?

frontend-design from vercel-labs/agent-eval embeds critique-and-iterate evaluation loops rather than emitting a single layout. Agents review hierarchy, spacing, and distinctiveness before finalizing component structures.
