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	```
111
