Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries the full burden. It does disclose real behavioral information not present in the schema: results come back as JSON, and DataTable assets return rows instead of a property map. It says nothing about error behavior for a bad path, permissions, or whether non-datatable assets return nested structures.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
