Axiom Accessibility

Accessibility

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

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)

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. App Store accessibility rejection or Nutrition Labels → 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
