Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It does disclose the return structure (five named dimensions with score/max and evidence, plus grade and total /100), which is genuine behavioral context, but it says nothing about error/not-found handling, whether scores are cached or computed live, or cost/latency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
