Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0 parameters with 100% coverage, so no parameter documentation is needed. The description appropriately doesn't discuss parameters, focusing instead on the tool's output semantics (positions in X, Y, Z). This adds value beyond the schema by clarifying what data is returned, though it doesn't detail the return format (e.g., units, coordinate system).
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
