Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so name, siteId and confirm are already fully documented in the schema, and the description's 'confirm:true required' merely restates it. No additional syntax, format or interaction detail about the identity parameters is added, so baseline 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
