Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% description coverage, with the single parameter 'name' documented as 'Taxonomy name to search'. The description doesn't add any meaningful semantic information beyond what the schema already provides (e.g., it doesn't clarify search semantics like case sensitivity, partial matching, or examples). Given the high schema coverage, the baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
