Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% (one parameter 'query' with description 'IP address or hostname'). The description adds a slight nuance by specifying 'internet-exposed host', which clarifies the scope of the query. However, it does not elaborate on input format, validation, or examples. At high coverage, the baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
