WHY IT NEEDS A POLICY

Why set_bulb_color needs a policy

The tool likely sets the color of a smart bulb, which is a reversible modification of device state. This is a Write operation — it changes hardware state but can be undone by setting a different color. The description is empty, so confidence is reduced, but the naming convention and sibling tools strongly suggest this is a Write operation.

From the tool's definition Tool name 'set_bulb_color' and server context describe controlling smart bulbs via UDP network communication; sibling tools include 'set_bulb_brightness', 'turn_on_bulb', 'turn_off_bulb' indicating Write-type control operations.
