Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the full burden of behavioral disclosure. It does reveal the important requirement that confirm must be set to true, which is a useful safety detail. However, it does not mention the destructive nature of the action, permissions, or the consequence of not setting confirm, leaving other behavioral traits undisclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
