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 for the undocumented 'bucket' parameter. It only restates that the parameter identifies the bucket to delete, adding no format, example, or pointer to list_buckets for obtaining valid values. The 'must be empty' clause describes a bucket state, not the parameter's meaning, so it adds little beyond what the schema property name already implies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
