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 successfully conveys the polling mechanism and timeout concept, but omits critical behavioral details: whether the tool blocks execution during waiting, what specific value/object is returned upon completion vs. timeout, and whether timeout raises an exception or returns a specific status.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
