Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% and every enum (mode, task, depth) is documented inline, so the schema does the heavy lifting. The description simply repeats the mode names already enumerated in the schema and adds no syntax, defaults, or interaction detail beyond it — baseline 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
