Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema is empty (0 parameters), but the description lists plausible fields (title, description, timezone) that give some semantic hint about what can be updated. While it doesn't enumerate all possible settings or parameter types, the baseline for 0-param tools is 4, and the examples provide minimal compensation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
