Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. The verb 'gets' and the mention of 'metadata' imply a read-only operation, but the description does not explicitly state that it does not modify data or address error behaviors (e.g., what happens with an invalid matchId). There is no contradiction with annotations since none exist, but the description adds limited behavioral context beyond the obvious safe-read implication.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
