Accessibility
You MUST use this skill for ANY accessibility work including VoiceOver, Dynamic Type, color contrast, WCAG compliance, and UX flow auditing.

Cross-Suite Routes
- Full watchOS development context → See axiom-watchos
- Live accessibility validation on the simulator (set toggles, assert announcements) →
simulator-tester agent + xcui — see axiom-tools (skills/xcui-ref.md)

}
- ANY VoiceOver, Dynamic Type (including tvOS Large Text), contrast, touch target, or WCAG issue →
skills/accessibility-diag.md
- Assistive Access (cognitive disabilities, iOS 17+) →
skills/accessibility-diag.md
- App Store accessibility rejection or Nutrition Labels →
skills/accessibility-diag.md
- Reading app: VoiceOver stops at paragraphs/pages, Speak Screen halts →
skills/accessibility-diag.md
- UX dead ends, dismiss traps, buried CTAs, missing states →
skills/ux-flow-audit.md
- watchOS-specific accessibility (rotor on Digital Crown, AssistiveTouch, Double Tap) →
skills/watchos-a11y.md
- Want automated accessibility scan? →
accessibility-auditor agent or /axiom:audit accessibility
Automated Scanning
Accessibility audit → Launch accessibility-auditor agent or /axiom:audit accessibility
- VoiceOver labels and hints
- Dynamic Type violations
- Color contrast failures
- WCAG compliance scanning
UX flow audit → Launch ux-flow-auditor agent
- Dead-end views, dismiss traps
- Buried CTAs, missing empty/loading/error states
- Deep link dead ends, accessibility dead ends
Critical Patterns
Image Accessibility
- Use
Image(decorative: "photo") for purely decorative images — automatically hidden from VoiceOver (equivalent to accessibilityHidden(true) but semantically clearer)
- Use
accessibilityInputLabels() for buttons with complex or changing labels — improves Voice Control accuracy by providing alternative labels
- Respect
accessibilityDifferentiateWithoutColor environment value — when active, provide non-color cues (icons, patterns, labels) alongside color indicators
Anti-Rationalization
| Thought | Reality |
|---|
| "I'll add VoiceOver labels when I'm done building" | Accessibility is foundational, not polish. accessibility-diag prevents App Store rejection. |
| "My app doesn't need accessibility" | All apps need accessibility. It's required by App Store guidelines and benefits all users. |
| "Dynamic Type just needs .scaledFont" | Dynamic Type has 7 common violations. accessibility-diag catches them all. |
| "Color contrast looks fine to me" | Visual assessment is unreliable. WCAG ratios require measurement. accessibility-diag validates. |
| "UX issues are just polish" | UX dead ends cause 1-star reviews. They're defects, not enhancements. |
| "The dismiss gesture handles it" | fullScreenCover has no dismiss gesture. That's the trap. |
