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 states the tool removes all items, implying a destructive action, but fails to detail critical aspects like whether this action is reversible, requires specific permissions, or has side effects (e.g., stopping active renders). This leaves significant gaps in understanding the tool's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
