Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description shoulders the burden. It adds a useful behavioral instruction (cite source URLs and Asha article URLs when present), which informs the agent's output behavior. However, it does not disclose search behavior details like recency definition, result ordering, or potential limitations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
