Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of behavioral disclosure. It adds a 'CRITICAL' note about the required matchId provenance, which is helpful. However, it does not disclose potential failure modes, return structure, or any side effects. It is not misleading but leaves some transparency gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
