Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description compensates by listing preferred profile fields and explicitly prohibiting certain fields (city, dates, raw constraints). This adds semantic meaning to the user_profile object beyond its generic schema definition, though the 'merge' parameter is left unexplained.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
