Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Since no annotations are provided, the description carries the burden of behavioral disclosure. It clearly states that the tool only clears local state and does not access the web, which is valuable behavioral context. It also emphasizes the safety precondition of user confirmation. It does not detail side effects or response behavior, but for this simple local utility the key traits are covered.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
