Review website images for high-density displays, where standard assets can look blurry. Check higher-resolution versions, HTML and CSS image selection, delivery settings, and loading behavior, then identify specific files or components that need changes.
Use when reviewing image assets, markup, and CDN or build transforms related to Support high-DPI retina displays. Check encoded size, rendered size, loading strategy, and above-the-fold impact together.
Review the instructions the agent will receive before you install.
Standard images look blurry on retina displays (2x, 3x pixel density)—high-resolution assets ensure sharp visuals on modern devices.
Check if high-resolution images are provided for retina displays (2x, 3x).
Add retina-ready images using srcset or CSS image-set for high-DPI displays.
Explain how retina images ensure sharp visuals on high-density displays.
Review image assets, markup, and delivery configuration related to Support high-DPI retina displays. Flag exact files or components where format choice, sizing, or loading behavior violates the rule, and describe how to confirm the fix in DevTools.

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.
