Responsiveness Check

The responsiveness-check skill allows AI agents to programmatically verify how web pages render across different screen sizes and devices. It executes automated tests to ensure layouts remain functional and visually correct on mobile, tablet, and desktop interfaces.

When to use it

• Validate new responsive design implementations before deploying to production environments.
• Audit existing websites for broken layouts or overlapping elements on specific device widths.
• Integrate into CI/CD pipelines to automatically flag regression issues in UI rendering.
• Test complex grid systems or flexbox arrangements that may behave unexpectedly on smaller screens.

Key capabilities

• Simulates multiple viewport sizes and device types during testing.
• Detects layout shifts, overflow errors, and broken navigation elements.
• Provides detailed reports on which specific breakpoints fail validation.
• Supports custom configuration for testing particular devices or resolutions.

Example prompts

"Run a responsiveness check on my homepage to identify any mobile layout issues." "Test the checkout page across tablet viewports and report any overlapping text blocks." "Automate a full responsive audit of all pages in my documentation site before the next release."

Tips & gotchas

Ensure your website is fully loaded and stable before running responsiveness checks to avoid false positives from loading states. For best results, combine this skill with visual regression testing tools to catch subtle design inconsistencies that automated metrics might miss.
