Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the baseline is 3 even though the description adds nothing about parameters. However, the parameters (url, host, json, zone) are completely disconnected from the stated catalog purpose, and the description provides no mapping between them and the tool's behavior.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
