Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema covers the single parameter 'id' with a description ('Saved account ID.'), achieving 100% schema coverage. The tool description does not mention parameters, so it adds no meaning beyond the schema. Per the rubric, when schema coverage is high, the baseline score is 3, and the description neither improves nor worsens the semantic understanding.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
