Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full behavioral disclosure burden. It does disclose the source ('public home feed') and the freshness angle ('fresh'), which conveys a low-risk read operation. But it does not describe return shape, story count, pagination, or any operational limits, leaving some gaps for a tool with zero annotation safety signals.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
