Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavior on its own. It states that it returns the highest or lowest rows by a numeric column, which covers the core behavior. However, it does not mention default ordering, the meaning of limit, or potential limitations such as ties or non-numeric column handling.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
