Single tool 'get_description' has empty input schema (no properties defined) and minimal description (28 chars). Tool appears to be a stub or placeholder with no actual parameters or meaningful documentation. No evidence of parameter descriptions, output schema documentation, or error handling guidance. This server exposes only one tool with critical definition gaps.

• Expand tool description to 50 - 200 characters explaining: what entity's description is returned, when to call it, and what structure to expect. E.g., 'Retrieve the Home Assistant device's metadata including name, type, area, and supported capabilities. Call this first to understand what actions the device supports.'
• Define explicit input schema with required parameters. If the tool retrieves a specific device, add a 'device_id' parameter with description 'The Home Assistant device identifier (string, required)'. If it retrieves the gateway's own description, document that it takes no parameters.
• Document the output schema with typed fields. E.g., {type: object, properties: {device_id: {type: string}, name: {type: string}, device_type: {type: string}, capabilities: {type: array, items: {type: string}}, ...}}
• Add error handling guidance: 'If device_id is invalid, returns error with available device IDs. If device is offline, returns cached metadata with a 'stale' flag.'
• Rename tool to be more specific: 'get_device_description', 'get_device_metadata', or 'describe_device' to clarify the subject and action.
