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 does not clarify whether this call blocks execution, yields to the game loop, or can be interrupted; it also says nothing about return behavior. 'Wait N frames' is minimally descriptive but omits important execution semantics.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
