Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It discloses an important behavioral trait—that the VM will reboot normally after exiting recovery mode—but it does not mention potential downtime, prerequisites, or whether recovery mode must be active. The reboot detail adds value, but the description is otherwise sparse.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
