What
Extension error messages are now mapped to specific types such as timeouts, missing tabs, blocked navigation, denied permissions, expired sessions and blocked domains, alongside sets of tool names including switch_browser, list_connected_browsers and select_browser. This feeds reporting rather than anything you see.
