Our review

This skill performs a comprehensive UI/UX audit of frontend codebases, analyzing component structure, accessibility, responsiveness, visual consistency, and UX patterns.

Strengths

  • Automates code-level checks for common UI issues like missing alt text or hardcoded colors.
  • Supports persona-based reviews for tailored feedback.
  • Outputs findings with severity levels and fix suggestions.

Limitations

  • Relies on static code analysis; cannot fully assess visual or interactive aspects.
  • Limited to codebases with supported frameworks (React, Vue, Svelte, etc.).
  • May produce false positives or miss context-dependent design decisions.
When to use it

Use when you need a quick, systematic evaluation of a UI codebase's quality and adherence to best practices.

When not to use it

Avoid for purely visual design reviews where code is unavailable, or for final accessibility audits that require manual testing.

Security analysis

Safe
Quality score90/100

The skill only executes read-only file analysis commands (grep, find) on user-specified codebases; no destructive actions, data exfiltration, or obfuscation are present. Commands are transparent and limited to diagnostic purposes.

/ui-review — UI/UX Audit

Usage

/ui-review [--target <path|url>] [--as <persona>] [--mode quick|standard|deep]
  • --target — directory, file, or URL to review (default: current working directory)
  • --as <persona> — load reviewer persona from .claude/personas/<persona>.md
  • quick — layout + accessibility + obvious issues only
  • standard — full audit across all 7 categories (default)
  • deep — standard + component-level analysis + refactor suggestions

Step 0 — Preflight

Identify the UI stack:

# Check package.json for frameworks
grep -l "react\|vue\|svelte\|angular\|next\|nuxt" "${TARGET:-.}/package.json" 2>/dev/null | head -5
# Count UI files
find "${TARGET:-.}" -type f \( -name "*.tsx" -o -name "*.jsx" -o -name "*.vue" -o -name "*.svelte" -o -name "*.html" \) 2>/dev/null | wc -l

Load persona if --as specified:

  • Read .claude/personas/<persona>.md
  • Apply that reviewer's lens to all findings below

Step 1 — Component Structure Analysis

find "${TARGET:-.}" -type f \( -name "*.tsx" -o -name "*.jsx" -o -name "*.vue" \) 2>/dev/null | head -30

Check for:

  • Component files > 200 lines (split concern smell)
  • Missing prop validation / TypeScript types on UI components
  • Inline styles (> 3 occurrences is a smell)
  • God components (single file doing layout + state + data fetch)
grep -rn "style={{" "${TARGET:-.}" --include="*.tsx" --include="*.jsx" 2>/dev/null | wc -l
grep -rn "useState\|useEffect\|fetch\|axios" "${TARGET:-.}/src" --include="*.tsx" --include="*.jsx" 2>/dev/null | head -10

Step 2 — Accessibility Audit (a11y)

grep -rn "<img " "${TARGET:-.}" --include="*.tsx" --include="*.jsx" --include="*.vue" --include="*.html" 2>/dev/null | grep -v 'alt=' | head -20
grep -rn "<button\|<a " "${TARGET:-.}" --include="*.tsx" --include="*.jsx" 2>/dev/null | grep -v "aria-label\|aria-describedby\|title=" | head -20
grep -rn "onClick.*div\|onClick.*span" "${TARGET:-.}" --include="*.tsx" --include="*.jsx" 2>/dev/null | head -10
grep -rn "tabIndex\|role=" "${TARGET:-.}" --include="*.tsx" --include="*.jsx" 2>/dev/null | head -10

Flags:

  • <img> without alt → HIGH (WCAG 1.1.1)
  • Click handlers on div/span → MEDIUM (keyboard inaccessible)
  • Missing aria-label on icon buttons → MEDIUM
  • tabIndex="-1" on focusable elements → check intent

Step 3 — Responsiveness & Layout

grep -rn "px-\|width:\|height:" "${TARGET:-.}" --include="*.tsx" --include="*.jsx" --include="*.css" 2>/dev/null | grep -v "min-\|max-\|%" | head -20
grep -rn "overflow:\s*hidden\|overflow-hidden\|truncate" "${TARGET:-.}" 2>/dev/null | head -10
grep -rn "@media\|sm:\|md:\|lg:\|xl:" "${TARGET:-.}" 2>/dev/null | wc -l

Flags:

  • Fixed pixel widths on containers (not max-width) → MEDIUM
  • No responsive breakpoints in layout components → MEDIUM
  • Content overflow hidden without visible affordance → LOW

Step 4 — Visual Consistency

# Check for color/spacing values hardcoded outside design tokens
grep -rn "#[0-9a-fA-F]\{3,6\}\|rgb(\|rgba(" "${TARGET:-.}" --include="*.tsx" --include="*.jsx" --include="*.css" 2>/dev/null | grep -v "theme\|token\|var(--\|tailwind" | head -20
# Check for magic spacing numbers
grep -rn "margin:\s*[0-9]\|padding:\s*[0-9]\|gap:\s*[0-9]" "${TARGET:-.}" --include="*.css" 2>/dev/null | head -20

Flags:

  • Hardcoded color values outside design tokens → MEDIUM (consistency drift risk)
  • Magic spacing numbers outside scale → LOW
  • Multiple font sizes not from a defined scale → MEDIUM

Step 5 — UX Pattern Check

grep -rn "loading\|isLoading\|skeleton\|spinner" "${TARGET:-.}" --include="*.tsx" --include="*.jsx" 2>/dev/null | head -10
grep -rn "error\|catch\|onError\|fallback" "${TARGET:-.}" --include="*.tsx" --include="*.jsx" 2>/dev/null | head -10
grep -rn "empty\|isEmpty\|noData\|no.*result" "${TARGET:-.}" --include="*.tsx" --include="*.jsx" 2>/dev/null | head -10
grep -rn "toast\|notification\|alert\|feedback" "${TARGET:-.}" --include="*.tsx" --include="*.jsx" 2>/dev/null | head -10

Check coverage of UI states:

  • [ ] Loading state
  • [ ] Error state
  • [ ] Empty state
  • [ ] Success feedback

Missing states → MEDIUM (user confusion in edge cases).


Step 6 — Performance Red Flags

# Re-renders: anonymous functions in JSX
grep -rn "onClick={() =>" "${TARGET:-.}" --include="*.tsx" --include="*.jsx" 2>/dev/null | wc -l
# Missing keys in lists
grep -rn "\.map(" "${TARGET:-.}" --include="*.tsx" --include="*.jsx" 2>/dev/null | grep -v "key=" | head -20
# Large image without lazy loading
grep -rn "<img " "${TARGET:-.}" --include="*.tsx" --include="*.jsx" --include="*.html" 2>/dev/null | grep -v "loading=\|lazy" | head -10

Flags:

  • .map() without key prop → HIGH (React reconciliation issues)
  • Anonymous arrow functions in render at scale (> 20 occurrences) → LOW
  • Images without loading="lazy" in long lists → LOW

Step 7 — Security in UI

grep -rn "dangerouslySetInnerHTML\|innerHTML\|document\.write\|v-html" "${TARGET:-.}" --include="*.tsx" --include="*.jsx" --include="*.vue" 2>/dev/null | head -10
grep -rn "localStorage\.\|sessionStorage\." "${TARGET:-.}" --include="*.tsx" --include="*.jsx" 2>/dev/null | grep -v "test\|spec" | head -10
  • dangerouslySetInnerHTML without sanitization → CRITICAL (XSS)
  • Sensitive data (tokens, keys) in localStorage → HIGH
