Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the visible outcome (finding an opponent and revealing their stance) but does not disclose whether this operation has side effects on the queue, costs anything, requires state, or blocks waiting. The description is not misleading, but it is incomplete for a tool with no annotation safety profile.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
