accessibility

The accessibility skill helps teams design, implement, and audit inclusive digital experiences that align with WCAG 2.2 Level AA standards. It focuses on ensuring that interfaces are Perceivable, Operable, Understandable, and Robust (POUR) for users with diverse accessibility needs, including individuals using screen readers, keyboard navigation, switch controls, and other assistive technologies. The skill supports accessibility-first development by guiding the use of semantic structures, proper labeling, focus management, and robust compatibility patterns across modern digital platforms.

This skill provides structured guidance for mapping UI requirements into accessible technical implementations for Web, iOS, and Android environments. It includes support for semantic HTML and WAI-ARIA on the web, accessibility traits and labels in SwiftUI, and semantic modifiers and content descriptions in Android Compose. The skill addresses key WCAG 2.2 requirements such as minimum target sizes, visible focus indicators, responsive zoom and reflow behavior, descriptive error handling, redundant data entry prevention, and live region announcements for dynamic updates. It also emphasizes the importance of accessibility trees, semantic mapping, and correct Name, Role, Value implementation patterns.

Typical use cases include auditing applications for accessibility compliance, defining accessible component specifications, implementing accessible navigation flows, and translating design requirements into platform-specific accessibility attributes. The skill is intended for frontend developers, mobile engineers, UI architects, QA specialists, accessibility auditors, and design system teams who need to build or maintain accessible user experiences across multiple platforms.
