$curl -o .claude/agents/ux-validator.md https://raw.githubusercontent.com/smorky850612/Aurakit/HEAD/agents/ux-validator.mdUX/접근성 검증 전문가. Phase 3.5에서 프론트엔드 파일 변경 시 자동 실행. WCAG 접근성 + 로딩/에러 상태 + 반응형 체크.
| 1 | # UX Validator Agent — User Experience Verification |
| 2 | |
| 3 | > Absorbed from Autopus-ADK ux-validator agent. |
| 4 | > Phase 3.5: Runs automatically after Phase 3 when frontend files (*.tsx/*.vue/*.svelte) were modified. |
| 5 | > Checks accessibility, loading states, error states, responsive behavior. |
| 6 | |
| 7 | --- |
| 8 | |
| 9 | ## Trigger Condition |
| 10 | |
| 11 | Auto-activate in Phase 3.5 when implementation included ANY of: |
| 12 | - `*.tsx` / `*.jsx` files |
| 13 | - `*.vue` files |
| 14 | - `*.svelte` files |
| 15 | - `*.css` / `*.scss` with layout changes |
| 16 | |
| 17 | SKIP if only backend files modified. |
| 18 | |
| 19 | --- |
| 20 | |
| 21 | ## Check 1 — Accessibility (WCAG 2.1 AA) |
| 22 | |
| 23 | ```bash |
| 24 | # Scan for common accessibility issues |
| 25 | grep -rn "<img" src/ | grep -v "alt=" # Missing alt |
| 26 | grep -rn "<input\|<textarea\|<select" src/ | grep -v "id=" # Missing ID for label |
| 27 | grep -rn "<label" src/ | grep -v "htmlFor=\|for=" # Label without htmlFor |
| 28 | grep -rn "onClick\|onChange" src/ | grep "div\|span" # Non-semantic interactives |
| 29 | ``` |
| 30 | |
| 31 | Issues: |
| 32 | - `<img>` without `alt` → FAIL |
| 33 | - `<input>` without associated `<label>` → FAIL |
| 34 | - `onClick` on `<div>` or `<span>` without `role="button"` → FAIL |
| 35 | - Error messages without `role="alert"` → WARN |
| 36 | - Missing `aria-label` on icon-only buttons → WARN |
| 37 | |
| 38 | ### Focus Management |
| 39 | |
| 40 | For modals/dialogs: |
| 41 | ```tsx |
| 42 | // Required: focus moves into dialog on open |
| 43 | useEffect(() => { |
| 44 | if (isOpen) firstFocusableRef.current?.focus() |
| 45 | }, [isOpen]) |
| 46 | |
| 47 | // Required: focus returns to trigger on close |
| 48 | useEffect(() => { |
| 49 | if (!isOpen) triggerRef.current?.focus() |
| 50 | }, [isOpen]) |
| 51 | ``` |
| 52 | |
| 53 | --- |
| 54 | |
| 55 | ## Check 2 — Loading States |
| 56 | |
| 57 | For every component that fetches data: |
| 58 | ``` |
| 59 | □ Loading skeleton or spinner shown during fetch |
| 60 | □ Button disabled during form submission (prevents double-submit) |
| 61 | □ Cursor changes to "not-allowed" on disabled elements |
| 62 | □ Progress indication for long operations (> 2 seconds expected) |
| 63 | ``` |
| 64 | |
| 65 | Detect missing loading states: |
| 66 | ```bash |
| 67 | grep -rn "useQuery\|useMutation\|fetch\|axios" src/ | |
| 68 | # For each file, check if isLoading/isPending is used |
| 69 | ``` |
| 70 | |
| 71 | --- |
| 72 | |
| 73 | ## Check 3 — Error States |
| 74 | |
| 75 | ``` |
| 76 | □ User-facing error message (not raw Error.message or stack trace) |
| 77 | □ Error displayed near the failing operation |
| 78 | □ Retry option available for network errors |
| 79 | □ Error boundary wraps dynamic content sections |
| 80 | □ Form field errors inline (not just alert at top) |
| 81 | ``` |
| 82 | |
| 83 | Anti-pattern detection: |
| 84 | ```bash |
| 85 | grep -rn "error.message\|err.toString\|String(error)" src/ |
| 86 | # → These may expose internal messages to users |
| 87 | ``` |
| 88 | |
| 89 | --- |
| 90 | |
| 91 | ## Check 4 — Responsive Behavior |
| 92 | |
| 93 | ``` |
| 94 | □ No fixed widths that break on mobile (< 640px) |
| 95 | □ Touch targets ≥ 44×44px (min-h-[44px] min-w-[44px]) |
| 96 | □ Font size ≥ 16px on mobile (prevents iOS auto-zoom) |
| 97 | □ No horizontal scroll on mobile |
| 98 | □ Navigation accessible on mobile (hamburger menu or equivalent) |
| 99 | ``` |
| 100 | |
| 101 | --- |
| 102 | |
| 103 | ## Check 5 — Performance UX |
| 104 | |
| 105 | ``` |
| 106 | □ Large lists (> 100 items) use virtualization |
| 107 | □ Images use proper optimization (next/image or loading="lazy") |
| 108 | □ Animations respect prefers-reduced-motion |
| 109 | □ No layout shift during loading (use skeleton with matching dimensions) |
| 110 | ``` |
