## Why browser_press_key is rated High

This tool executes a keyboard key press action within a browser context, which is an external operation that could trigger form submissions, navigation, or other browser behaviors. It falls under Execute as it performs browser automation actions whose effects depend on which key is pressed and the current browser state.

From the tool's own definition: "'Press keyboard key in browser' — triggers an external browser interaction/UI action"

AI agents invoke browser_press_key to trigger actions in Claude Mobile. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
