Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, but the description compensates by explaining workspace_name: 'Optional name of the workspace directory to filter inbox items.' This adds meaning beyond the bare schema (string/null, default null), clarifying it is a filter and optional. However, it doesn't specify behavior when omitted or provided, but the core semantics are covered.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
