Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full disclosure burden. It does reveal the behavioral effect ('disconnect') beyond the name, but says nothing about idempotency, whether it errors when nothing is running, whether it affects only this session/client, or whether it is reversible.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
