Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare this is not read-only, is open-world, idempotent, and non-destructive, but the description adds no behavioral context on top of that — nothing about side effects, whether a review is recorded or dispatched externally, latency, or what happens on repeated calls with the same review_id. It does not contradict the annotations, but for an open-world mutation tool it carries almost none of its own weight.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
