Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations are sparse (no read-only or destructive hints), so the description carries the burden. It discloses that the tool returns a request id, quotes, and recommendation, and that no work is done. However, it does not mention potential side effects like reserving resources or whether quotes are binding, leaving 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.
