## Why android_disconnect is rated Medium

This tool performs a connection state modification rather than data deletion. Disconnecting from a device and releasing resources is a reversible action - the device remains intact and can be reconnected to. This is Write category (modifies state reversibly) rather than Destructive (which would require permanent data loss).

From the tool's own definition: "'Disconnect from current Android device and release ADB resources' - this modifies the state of the connection to an Android device by terminating it, which is a reversible state change (can reconnect)."

## Use case

AI agents use android_disconnect to create or update resources in Android, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Android environment.

## Recommended policy (PolicyLayer)
