Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate, and it does partially: it clarifies that the required string can be an id or a name, and that "N" in the returned dates corresponds to the `upcoming` parameter. The documented constraint on `upcoming` (default 6, range 1-36) is not repeated in prose, but it is visible in the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
