Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds meaning by specifying that parameters define a 'date range', which clarifies the purpose of 'start_date' and 'end_date' beyond their schema titles. However, with 0% schema description coverage, it doesn't fully compensate by detailing format (e.g., YYYY-MM-DD) or constraints, so it meets the baseline for partial value.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
