Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It only lists the resource and scope, without detailing side effects, read-only nature, or output format. While 'Get' implies a read operation, it does not explicitly confirm safety or describe what is returned beyond the leaderboard list.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
