Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has zero parameters, and the description covers the schema completely. The description adds value by specifying the returned fields (name, email), which is beyond what the empty schema provides. According to guidelines, a baseline of 4 is appropriate for zero parameters when description adds context.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
