Check a page for duplicate accesskey values, which define keyboard shortcuts for elements. Identify conflicting assignments, suggest unique values or removal, and describe how to verify keyboard behavior with browser accessibility tools or assistive technology.
Use when reviewing rendered HTML, interactive components, or design-system patterns related to Ensure accesskey values are unique. 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.
Duplicate access keys cause conflicts where only one element (usually the first) is reachable via the shortcut, making other elements inaccessible to keyboard users.
accesskey attribute value must be unique on the pageCheck for duplicate accesskey attributes across the document to ensure each shortcut is unique.
Assign unique values to each accesskey attribute or remove redundant ones to prevent shortcut conflicts.
Explain how duplicate access keys affect keyboard accessibility and browser shortcut handling.
Review the rendered markup and interactive states that affect Ensure accesskey values are unique. 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.
