Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden. It states the tool returns the current weight set, which largely restates the tool name. It does not disclose the output format, whether the operation is read-only, or any caveats about data freshness. The phrase 'currently recommending' adds minor behavioral context but is not substantial.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
