Accessibility

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

<!-- AXIOM_AUDITOR_INLINE_BEGIN — rewritten for Codex by scripts/build-codex.ts; do not hand-edit -->

Auditors are skills here. Where this router says "Launch some-auditor agent", invoke the

matching Codex skill instead — same procedure, no Claude Code agent required.

Available: axiom-audit-accessibility, axiom-audit-concurrency, axiom-audit-swiftdata, axiom-audit-swiftui-nav, axiom-audit-ux-flow.

The ones that shell out — builds, tests, simulators, crash symbolication — need shell access to run.

Quick Reference

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)
• Asserting VoiceOver speech in an XCUITest (XCUIDevice.shared.voiceOverService, OS27) → axiom-testing (skills/ui-testing.md Pattern 7)

1. ANY VoiceOver, Dynamic Type (including tvOS Large Text), contrast, touch target, or WCAG issue → skills/accessibility-diag.md
2. Assistive Access (cognitive disabilities, iOS 17+) → skills/accessibility-diag.md
3. Accessibility Nutrition Labels, or an App Review note about accessibility → skills/accessibility-diag.md
4. Reading app: VoiceOver stops at paragraphs/pages, Speak Screen halts → skills/accessibility-diag.md
5. UX dead ends, dismiss traps, buried CTAs, missing states → skills/ux-flow-audit.md
6. watchOS-specific accessibility (rotor on Digital Crown, AssistiveTouch, Double Tap) → skills/watchos-a11y.md
7. Want automated accessibility scan? → accessibility-auditor agent or axiom-audit-accessibility

Automated Scanning

Accessibility audit → axiom-audit-accessibility

• VoiceOver labels and hints
• Dynamic Type violations
• Color contrast failures
• WCAG compliance scanning

UX flow audit → axiom-audit-ux-flow

• 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
