Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It discloses that the execution status is private, gives a security-critical instruction about token placement, and defines a polling termination condition. This adds meaningful behavioral context, though error handling and return details are not covered.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
