building-accessible-ui
MUST BE USED for any UI work. Invoke this skill before generating, modifying, or reviewing any code that renders, styles, or wires up a user-facing interface — including markup, components, templates, styles, and the JavaScript/TypeScript that drives them. This skill encodes the accessibility (WCAG 2.2 AA) requirements every UI change must satisfy; skipping it produces inaccessible output. Applies across web, mobile, and desktop. If the task touches the UI layer in any way, use this skill first.
