Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 50%: the idempotencyKey parameter has a rich description in the schema, but the profile parameter has no description beyond its nested properties. The tool description doesn't add parameter-level semantics beyond what the schema provides. The profile object's properties are self-descriptive (name, status, cantons, etc.), and the idempotencyKey's schema description is thorough. The description's mention of 'bounded watch profile' and review scope adds some context for the profile parameter, but it doesn't compensate for the missing profile description. Baseline 3 is appropriate given the partial schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
