Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It transparently describes the output structure (aggregate score, weakest-link, per-member breakdown) and the trust threshold logic (score >= 10 and 2+ members). While it does not discuss potential failure modes or operational details, it gives a clear picture of what the tool returns and its decision rule, which is sufficient for a read-only check.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
