Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% and the single 'text' parameter already has a clear description, length limits, and an example. The tool description adds broader purpose but not much parameter-specific detail, so the schema carries the load and the description neither hurts nor substantially improves parameter understanding.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
