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. 'Get' implies a read-only operation and 'where they must act' adds some state context, but the description does not disclose whether authentication is needed, what 'daily games' means precisely, or any rate-limit or scope caveats.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
