Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so every parameter (limit, offset, order_by, on_behalf_of, where_clause) is already documented in detail, including defaults, max values and pagination behaviour. The description only reinforces the where_clause column constraint that the schema already enumerates, so baseline 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
