What problem does it solve? UI changes often ship with accessibility regressions — poor color contrast, keyboard traps, missing focus indicators, or incorrect ARIA usage — that are only discovered after release. This Skill reviews UI code against a structured accessibility checklist so issues are caught with concrete file-and-line fixes before they reach users. ## Core Features & Use Cases - Contrast and Visual Checks: Verifies text and meaningful UI elements meet contrast ratios for their size and role, and that reduced-motion and zoom behavior are respected. - Keyboard and Focus Review: Confirms all interactive elements are keyboard-operable, tab order is logical, focus indicators are visible, and focus is managed correctly in modals, menus, and route changes. - Semantics and ARIA Audit: Checks that native elements are preferred, ARIA roles and attributes are used correctly, form fields have associated labels, and images have appropriate alt text. - Use Case: Before merging a new modal component, ask for an a11y review and receive a Pass / Fail / Requires-manual-review checklist with file:line references and concrete fixes, such as adding an aria-label to an icon-only button. ## Quick Start Ask the assistant to audit the accessibility of the form or modal you just changed and report any WCAG issues with fixes.
