Run a live performance test by pointing the skill at a WordPress URL to navigate 4–6 pages with Playwright, capturing actual page load timing, console errors, and network failures in a structured JSON report.
Yes, web vitals and load timing are measured across desktop (1920x1080) and 2–3 key mobile (375x812) viewports, capturing performance.timing data per page to compare real-world user experience.
Playwright detects console errors and network failures by capturing browser console messages and filtering network requests for non-2xx status codes, then correlating these mixed-content and 4xx/5xx failures to page behavior.
The performance JSON report output includes a visitedPages array detailing load times, categorized console messages, and filtered failed network requests for each tested page across desktop and mobile viewports.
Yes, Playwright MCP browser automation is required to navigate live pages, execute browser_evaluate for performance.timing, and capture console messages and network requests during the audit.
Validate network health and accessibility QA by running a multi-page audit that flags non-2xx network failures, mixed content, and JavaScript console errors, compiling the results into a structured JSON report.
