Use this skill whenever a user shares web code (HTML, JSX, TSX, Vue, Svelte) and wants to know if it's accessible — keyboard usable, screen reader compatible, WCAG compliant, or ready to ship from an a11y standpoint. The trigger is code + an accessibility question: "does this pass WCAG", "check this for a11y", "is this keyboard accessible", "audit before I ship", "compliance report for a client". Does NOT apply when the user wants to write new accessible components, understand WCAG concepts abstractly, find accessibility libraries, or write accessibility tests.
