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 mentions support for 'specific categories or keyword search', which is a behavioral trait, but lacks details about how the tool actually behaves (e.g., whether it returns a list, requires follow-up, or has restrictions). This is minimal but not absent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
