Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It lists 'backupId' as a required string parameter, matching the schema, but adds no semantic details (e.g., format, source, or validation rules). Since there's only one parameter, the baseline is 4, but the lack of extra meaning beyond the schema reduces it to 3, as it merely repeats the parameter name without context.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
