Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of disclosing behavioral traits. It describes the tool as a getter, implying a safe read operation, but does not explicitly state absence of side effects, auth requirements, or return format. Since it's an example fetcher, the minimal transparency is acceptable but not detailed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
