Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% description coverage, with each parameter having a clear description (e.g., 'The ID of the node to clone', 'New X position for the clone'). The tool description adds no extra meaning beyond the schema, so a baseline score of 3 is appropriate. However, note that 'nodeName' is described as 'Name of the node to modify' which might imply renaming the original, not naming the clone; this slight ambiguity is not corrected by the tool description.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
