Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of disclosing behavior. It states that the AI orchestrates multiple data sources and mentions a cost of $0.025, which are useful behavioral hints. However, it does not disclose whether the operation is read-only, what the response format might be, or potential side effects, leaving some transparency gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
