Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage and 4 parameters (including a nested object), the description provides no information about any parameters. It doesn't explain what 'userId', 'query.unread', 'startingAfter', or 'limit' mean, their expected formats, or how they affect the retrieval. The description fails to compensate for the complete lack of schema documentation, leaving all parameters semantically opaque.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
