Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema description coverage is 0%, so the description must compensate. It doesn't mention the 'taskId' parameter at all, leaving the single required parameter completely undocumented. However, with only one parameter, the baseline is 4, but the description adds no value beyond what's obvious from the tool name, so it scores lower.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
