JantonioFC Frontend Design Review
Review UI implementations against design quality standards and your design system OR create distinctive, production-grade frontend interfaces from scratch.
Two Modes
Mode 1: Design Review
Evaluate existing UI for design system compliance, three quality pillars (Frictionless, Quality Craft, Trustworthy), accessibility, and code quality.
Mode 2: Creative Frontend Design
Create distinctive interfaces that avoid generic "AI slop" aesthetics, have clear conceptual direction, and execute with precision.
Creative Frontend Design
Before coding, commit to an aesthetic direction:
- Purpose: What problem does this solve? Who uses it?
- Tone: minimal, maximalist, retro-futuristic, organic, luxury, playful, editorial, brutalist, art deco, soft/pastel, industrial, etc.
- Constraints: Framework, performance, accessibility requirements.
- Differentiation: What makes this distinctive and context-appropriate?
Aesthetics Guidelines
- Typography: Distinctive fonts that elevate aesthetics. Pair a display font with a refined body font. Avoid Inter, Roboto, Arial, Space Grotesk.
- Color & Theme: Cohesive palette with CSS variables. Dominant colors + sharp accents > timid, evenly-distributed palettes.
- Motion: CSS-only preferred. One well-orchestrated page load with staggered reveals > scattered micro-interactions.
- Spatial Composition: Asymmetry, overlap, diagonal flow, grid-breaking elements, generous negative space OR controlled density.
- Backgrounds: Gradient meshes, noise textures, geometric patterns, layered transparencies, dramatic shadows, grain overlays.
AVOID: Overused fonts, cliched color schemes, predictable layouts, cookie-cutter design without context-specific character.
Match implementation complexity to vision. Maximalist = elaborate code. Minimalist = restraint and precision.
Design Review
Design System Workflow
Before implementing:
- Review component in your Storybook / component library for API and usage
- Use Figma Dev Mode to get exact specs (spacing, tokens, properties)
- Implement using design system components + design tokens
During review:
- Compare implementation to Figma design
- Verify design tokens are used (not hardcoded values)
- Check all variants/states are implemented correctly
- Flag deviations (needs design approval)
If component doesn't exist:
- Check if existing component can be adapted
- Reach out to design for new component creation
- Document exception and rationale in code
Review Process
- Identify user task
- Check design system for matching patterns
- Evaluate aesthetic direction
- Identify scope (component, feature, or flow)
- Evaluate each pillar
- Score and prioritize issues (blocking/major/minor)
- Provide recommendations with design system examples
Core Principles
- Task completion: Minimum clicks. Every screen answers "What can I do?" and "What happens next?"
- Action hierarchy: 1-2 primary actions per view. Progressive disclosure for secondary.
- Onboarding: Explain features on introduction. Smart defaults over configuration.
- Navigation: Clear entry/exit points. Back/cancel always available. Breadcrumbs for deep flows.
Quality Pillars
1. Frictionless Insight to Action
Evaluate: Task completable in ≤3 interactions? Primary action obvious and singular?
Red flags: Excessive clicks, multiple competing primary buttons, buried actions, dead ends.
2. Quality is Craft
Evaluate:
- Design system compliance: matches Figma specs, uses design tokens
- Aesthetic direction: distinctive typography, cohesive colors, intentional motion
- Accessibility: Grade C minimum (WCAG 2.1 A), Grade B ideal (WCAG 2.1 AA)
Red flags: Generic AI aesthetics, hardcoded values, implementation doesn't match Figma, broken reflow, missing focus indicators.
3. Trustworthy Building
Evaluate:
- AI transparency: disclaimer on AI-generated content
- Error transparency: actionable error messages
Red flags: Missing AI disclaimers, opaque errors without guidance.

When to Use
Review and create distinctive, production-grade frontend interfaces with high design quality and design system compliance. Evaluates using three pillars: frictionless insight-to-action, quality craft, and trustworthy building.
