Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must add meaning to parameters. However, it adds no context beyond parameter names. 'message_id' is somewhat self-explanatory, but 'offset' and 'limit' are not explained regarding format, defaults, or whether offset is 0-based. The description does not compensate for the lack of schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
