WHY IT NEEDS A POLICY

Why agregar_dispositivo needs a policy

The name 'agregar_dispositivo' ('add device') strongly suggests a Write operation — creating/registering a new smart home device in the system. This is reversible (devices can typically be removed). Confidence is reduced due to the empty description, but the naming pattern and server context (smart home device management) support this classification.

From the tool's definition Tool name 'agregar_dispositivo' translates from Spanish as 'add device'. The description is empty and uninformative.
