Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema provides full descriptions for all three parameters, but the description adds critical semantic context: the priority of cursor over since, the effect of omitting both for a full crawl, and the mention of return fields (nextCursor, updatedAt). This significantly enhances the agent's understanding beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
