Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, with both `q` and `limit` fully described, so the schema does the heavy lifting and baseline is 3. The description's mention of partial `q` restates the schema, and it adds only the cross-reference that a returned value is meant to be used as `l` elsewhere.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
