Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden. It usefully discloses the side effects (household and primary entity creation), but omits whether the operation is irreversible, what permissions are needed, and what the 'confirm' flag does — meaningful gaps for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
