WHY IT NEEDS A POLICY

Why pwndbg_stop_monitor needs a policy

This tool executes a command to stop a background process (event monitor) in an LLDB debugging session. While not destructive of data and not reading/writing persistent data, it actively triggers an external operation (terminating a monitor) whose effects depend on the current session state. The ability to stop debugging monitors could disrupt analysis workflows or cause loss of monitored events.

From the tool's definition Tool name 'pwndbg_stop_monitor' and description 'Stop the background event monitor for a session' indicate an action that halts an active debugging process/monitor. This is an executable operation that modifies the runtime state of the debugger session.
