description: Check a website's phone, tablet, or desktop layout and interactions using Kitsuvo's responsive browser mode.

Open the requested page in a dedicated agent tab and pass its tab number to every tool. Use `browser_resize` with a device such as `iphone-16`, `pixel-8`, `ipad-air`, or `desktop`, or explicit `width` and `height`. On Windows, phones and tablets enable touch and a mobile user agent; reload if the site chooses its layout by user agent.

Inspect the snapshot at each requested size and test relevant navigation or controls within the user's scope. On Windows use `browser_take_screenshot` to verify visual layout; on macOS distinguish accessibility observations from visual checks you could not perform. If measuring overflow with `browser_evaluate`, use read-only DOM measurements, not script-based clicks or form submissions.

Record tested sizes, observable problems, and steps that reproduce them. Do not infer that an entire page is visually correct from its accessibility tree. In cleanup, call `browser_resize` with `off: true` on the test tab so it leaves responsive mode, including when a check fails.
