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 effectively describes a destructive action ('Clear') and its consequence ('requires re-authentication'), which are critical behavioral traits. However, it lacks details like whether this action is reversible, its impact on ongoing sessions, or error handling, leaving some gaps in transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
