Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 100% parameter descriptions, but they are generic ('ID of the resource') and unhelpful. The tool description adds no parameter-specific meaning; however, the parameter names (taxonomy_id, id) and the tool's purpose loosely imply roles. Per the baseline for high schema coverage, a 3 is appropriate, though the schema descriptions themselves are weak.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
