Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of behavioral disclosure. It states that the tool 'Returns fresh PEOPLE celebrity and entertainment stories', which indicates a read-only, non-destructive operation)Skip. However, it does not disclose details such as pagination, limits, or whether the response is a list, but for a simple no-parameter fetch this minimal context is adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
