Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations available, the description carries the behavioral disclosure burden. It clearly explains the sequence — graceful stop, 10-second wait, then start — which provides a transparent view of the operation's side effects (temporary downtime, orderly shutdown). It does not cover every possible implication (e.g., player disconnect), but the core behavior is well communicated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
