WHAT IT DOES

What tv_volume_down does on Smart Home Control MCP Server

WHY IT NEEDS A POLICY

Why tv_volume_down needs a policy

This tool sends a command to a physical TV device to change its volume state. It is an Execute-category action because it triggers an external hardware operation via ADB whose effect depends on the current state of the device. It is not purely a write (no data record is created/modified in a database) and not destructive or financial.

From the tool's definition Decrease TV volume — triggers an external operation on a physical device (Android TV) via ADB
