Review website animations against users’ reduced motion preferences, a setting that requests less movement. Check flashing content, scrolling effects, alternative transitions, pause controls, and advance warnings, and identify changes needed in rendered pages and interactive states.
Use when reviewing rendered HTML, interactive components, or design-system patterns related to Respect reduced motion preferences. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.
Review the instructions the agent will receive before you install.
Animations can trigger vestibular disorders, migraines, and seizures—respecting motion preferences makes your site usable for millions of affected users.
Verify that animations respect prefers-reduced-motion, no content flashes more than 3 times per second, parallax and scrolljacking effects have alternatives, and motion warnings appear before pages with excessive animation.
Use @media (prefers-reduced-motion: reduce) to disable animations. Ensure no flashing exceeds 3 flashes/second. Avoid motion behind static text. Provide motion warnings for immersive experiences.
Explain how motion affects users with vestibular disorders, photosensitive epilepsy, and cognitive disabilities, and why providing motion controls and warnings is essential for inclusive design.
Review the rendered markup and interactive states that affect Respect reduced motion preferences. Flag exact elements, roles, labels, focus behavior, or keyboard interactions that violate the rule, and note how to verify the fix with browser accessibility tooling or assistive tech.

Create and review custom 404 pages that help visitors recover from broken or moved links through search and navigation. Check the rendered page and HTTP response so missing content returns a proper 404 status.
Audit or create a dedicated About page that explains a website’s purpose and identifies its people or organization. Review the rendered output and supporting information, including expertise and contact details, to find gaps.
Review and add automated accessibility checks for components, pages, and continuous integration workflows. Use axe-based tools to detect structural and attribute issues, while identifying checks that still need keyboard or screen reader testing.
Review sign-in, registration, multi-factor authentication, and account recovery for accessibility barriers. Find blocked paste, difficult code entry, and inaccessible backup methods, then suggest authentication paths that support password managers, autofill, or device approval.
Review form errors, success messages, and live updates so screen reader users receive important notifications. Check the HTML delivered to the browser, announcement settings, display duration, and dismissal controls, then identify specific elements that need changes.
Review HTML tables so screen reader users can understand how headers and data relate. Check header markup, table descriptions, and merged cells, then identify specific fixes and ways to verify them.
