validating-accessibility

Use this skill when creating, modifying, or reviewing any .tsx component in apps/web, even if the user doesn't mention "accessibility." Covers semantic HTML, aria labels, navigation landmarks, forms, dialogs, and keyboard navigation. Trigger on: adding buttons, links, toggles, icons, or any interactive element; building or editing forms; adding dialogs or modals; reviewing UI code. Includes inline verification patterns for scanning violations. Not for styling or layout changes that don't involve interactive elements.
