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

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 toaccessibilityHidden(true)but semantically clearer) - Use
accessibilityInputLabels()for buttons with complex or changing labels — improves Voice Control accuracy by providing alternative labels - Respect
accessibilityDifferentiateWithoutColorenvironment 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. |
