Review mobile test coverage across real devices and simulated screen sizes. Find gaps in automated checks and CI, the workflow that runs project checks, and add Playwright tests for key mobile user flows.
Use when reviewing CI coverage, automated checks, or test strategy related to Test on real mobile devices and viewports. Focus on whether the rule is continuously verified, not just documented.
Review the instructions the agent will receive before you install.
More than 55% of global web traffic comes from mobile devices. Mobile browsers have different rendering engines, different font rendering, limited memory, real touch events that differ from mouse events, and system UI (notch, home indicator, keyboard) that intrudes on your layout. Issues like sticky hover states, touch target sizes, and keyboard layout shifts only appear on real devices.
Does this project have any mobile-specific test configurations? Check for Playwright device emulation, mobile viewport tests, or notes about mobile testing.
Add Playwright tests using mobile device presets to cover key user flows on mobile viewports.
Explain the difference between DevTools emulation and real device testing, common mobile-specific issues to test for, and how to use Playwright's device emulation.
Review tests, CI workflows, and enforcement points related to Test on real mobile devices and viewports. Flag exact gaps where the rule is not automatically verified or where failures do not block regressions.

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.
