• Visual inspection needed — screenshots, page layout verification, responsive testing
• Console debugging required — JavaScript errors, warnings, uncaught exceptions
• Performance analysis requested — Core Web Vitals, long tasks, resource bottlenecks
• Network monitoring desired — API calls, failed requests, slow resources, HAR recording
• Page comparison needed — before/after diff, staging vs production comparison
• Interaction recording — capturing video of user flows for documentation or bug reports
• Localhost development — testing local frontend applications during development
