Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It implies a destructive action ('Restarts') that could cause downtime or disruption, but doesn't specify critical details like required permissions, impact on users, expected duration, or error conditions. This is inadequate for a potentially disruptive operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
