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 but only mentions 'optional filtering' generically. It doesn't explain what the 5 parameters do, how they interact, or provide examples of valid values (e.g., what format for startTime/endTime, what activityTypes are available). The description adds minimal value beyond the bare schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
