Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema already provides a full description of the subscription_id parameter, including its format (MON-XXXXXX-XXXXXXXX), so the description adds no additional semantic value. With 100% schema coverage, a baseline score of 3 is appropriate; the tool description does not need to repeat what the schema already defines.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
