Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% description coverage, placing the burden on the description. The description adds value by giving examples for sensor_type (temperature, voltage, state), clarifying the optional filter parameter. However, the required hostname parameter is not explicitly described beyond being implied as the device identifier. This is adequate but incomplete compensation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
