Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so parameter documentation falls entirely on the description. The description provides concrete example values for every parameter ('mycompany', '@prefixes', 'com,net', 'eng', 20), which materially helps an agent understand expected formats without opening external docs. It still leaves some ambiguity around lang format and tlds syntax, but it compensates well.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
