Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of disclosure. It does state the return shape (JSON with fund details and active roster entries including specific fields), which is useful. However, it does not mention error behavior, access requirements, or whether only active funds can be queried.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
