Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the behavioral burden. It does convey that the operation is a non-destructive listing of all configured treasury accounts, which is minimally transparent. However, it does not mention pagination, permissions, error behavior, or output shape, though these are less critical for a parameterless list tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
