Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage for 5 parameters, the description doesn't compensate by explaining what the parameters mean. It mentions 'optional filtering' but doesn't specify which parameters provide filtering, what 'after', 'createdAfter', 'createdBefore', 'limit', or 'properties' mean, or how they should be used. The description adds minimal value beyond the bare schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
