Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 100% coverage for its single parameter 'count', but the tool description adds no value beyond that. It does not mention the parameter at all, leaving the agent without additional context (e.g., default value, allowed range, behavior when omitted). Baseline for high schema coverage would be 3, but lack of description contribution reduces the score.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
