Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema offers no property description (0% coverage), so the description's 'email (email of the new member)' does add the semantic context that the email belongs to the invited person. However, this mostly restates the parameter name and gives no format, uniqueness, or role expectations, so it only partially compensates for the schema gap.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
