Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden, yet it says nothing about reversibility, whether the public URL stops resolving, idempotency, or what error occurs if the webapp is already offline. "Take it offline" hints at effect but doesn't confirm it, which is thin for a state-changing operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
