Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate but fails to do so. It doesn't explain what 'userId' or 'data' represent, their formats, or how 'data' should be structured (e.g., key-value pairs for notification types). With 2 undocumented parameters, this leaves significant gaps in understanding.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
