frontend-design-review

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. USE FOR: PR reviews, design reviews, accessibility audits, design system compliance checks, creative frontend design, UI code review, component reviews, responsive design checks, theme testing, and creating memorable UI. DO NOT USE FOR: Backend API reviews, database schema reviews, infrastructure or DevOps work, pure business logic without UI, or non-frontend code.

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.
