Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the full behavioral burden. It discloses a cost of $0.01 USDC on Base, which is useful, but it does not explain permissions, rate limits, whether the operation is read-only, what happens for unsafe tokens, or what the audit result contains.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
