Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It only states 'Get menu items and prices', implying a read operation, but does not explicitly confirm no side effects, permissions needed, or rate limits. An agent might need to assume it's safe, but the description lacks explicit transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
