Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations are absent, so the description carries the full burden of behavioral disclosure. It does disclose a meaningful precondition (the order must be in 'Review' status), which is useful. But as a state-changing action, it omits key consequences: what status results from rejection, whether the action is reversible/final, and any effects on the order flow or payload. With zero annotation coverage, this is a significant gap for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
