WHY IT NEEDS A POLICY

Why browserbeam_wait needs a policy

This tool executes a synchronization or delay operation in browser automation. While 'wait' appears passive, it actively controls execution flow and can trigger subsequent actions based on DOM conditions or time. It is an Execute action because it triggers external operations (browser state monitoring/advancement) whose effects depend on the condition arguments provided.

From the tool's definition Tool name 'browserbeam_wait' and description indicate it waits for a condition (ms, selector, text, or until) before continuing—this controls browser automation flow and timing, which is an external operation trigger.
