Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioural traits. It lists return fields (submission_id, status, judging_started, disqualified, slot) and describes the solo practice auto-match behavior. It also mentions constraints like cost_usd must respect max_spend limits. However, it does not cover error cases or duplicate submission handling, which would improve transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
