Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full behavioral disclosure burden. It doesn't disclose behavior beyond the basic read operation, such as what fields are returned, whether the full address/phone are always present, error behavior for invalid IDs, or authentication/permission requirements. For a read tool the omission is a moderate gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
