+# iOS Accessibility Router
+
+**You MUST use this skill for ANY accessibility work including VoiceOver, Dynamic Type, color contrast, and WCAG compliance.**
+
+## When to Use
+
+Use this router when:
+- Fixing VoiceOver issues
+- Implementing Dynamic Type
+- Checking color contrast
+- Ensuring touch target sizes
+- Preparing for App Store accessibility review
+- WCAG compliance auditing
+- Assistive Access support (cognitive disabilities, iOS 17+)
+
+## Routing Logic
+
+### Accessibility Issues
+
+**All accessibility work** → `/skill axiom-accessibility-diag`
+- VoiceOver labels and hints
+- Dynamic Type scaling
+- Color contrast (WCAG)
+- Touch target sizes
+- Keyboard navigation
+- Reduce Motion support
+- Assistive Access (cognitive disabilities, iOS 17+)
+- Accessibility Inspector usage
+- App Store Review preparation
+
+### Automated Scanning
+
+**Accessibility audit** → Launch `accessibility-auditor` agent or `/axiom:audit accessibility` (VoiceOver issues, Dynamic Type violations, color contrast failures, WCAG compliance scanning)
+
+## Decision Tree
+
+1. ANY accessibility issue → accessibility-diag
+2. Want automated accessibility scan? → accessibility-auditor (Agent)
+
+## 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. |
+
+## 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
+
+#### accessibility-diag Coverage
+
+- 8 critical accessibility issues (including Assistive Access)
+- WCAG compliance levels (A, AA, AAA)
+- Assistive Access mode (cognitive disabilities, iOS 17+)
+- Accessibility Inspector workflows
+- VoiceOver testing checklist
+- App Store Review requirements
