Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden, yet it only asserts that a process is stopped. It does not disclose whether the operation is idempotent when nothing is running, whether it terminates the process forcibly or gracefully, whether any session state or data is lost, or what permissions are needed for a mutation-style action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
