Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema already documents the single query parameter with examples, so baseline is 3. The description adds meaningful semantic guidance by enumerating what kinds of queries are supported (cuisine, dish, neighborhood, city, vibe, or award), going beyond the schema's examples.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
