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 explains that the tool provides candidates and weighted tallies and that winners are promoted to the market, which is useful context beyond the empty schema. However, it does not explicitly state that the operation is read-only, has no side effects, or any authentication requirements. For a simple query tool this is acceptable, but more explicit disclosure would be stronger.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
