Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so limit, search and salonId are already fully documented, including the default, maximum and the 24-hex id pattern. The description restates the same facts ('up to 100 clients (20 by default)', 'across all the user's salons or one', 'only those whose name matches') rather than adding new semantics, so the baseline 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
