Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description is minimal and does not disclose behavioral traits such as the default inclusive behavior, return type, or edge case handling (e.g., when lower > upper). Annotations are absent, so the description carries full burden but fails to provide these details.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
