Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. For a tool that appears to move money, it says nothing about auth requirements, irreversibility, whether funds actually transfer, or what the 'flow' entails — leaving the agent unable to judge the risk of invoking it.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
