Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, but the description fully compensates by explaining the meaning, format, defaults, and valid values for all three parameters: date uses YYYY-MM-DD, view accepts 'report' or 'list', and limit is clamped to 1-30. This gives the agent everything needed to construct correct calls.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
