Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of disclosing behavior. It lists the return fields (price, sizes, shipping, delivery, return policy, order URL), giving a clear expectation of what the tool returns. Does not mention error behavior or side effects, but as a simple get, this is reasonable.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
