Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds no behavioral context beyond what the annotations already imply: readOnlyHint=false and destructiveHint=false. It does not say what happens to the container's state, whether a session must be active, whether the operation can fail on an already-stopped container, or what the response looks like.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
