Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden of behavioral disclosure. It states that the session is restarted, but it does not explain what is destroyed or cleared, whether an active session is required, whether the operation is idempotent, or whether prior reasoning is lost.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
