Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. 'Inspect' implies read-only, but it doesn't explicitly state side effects or permissions, and 'seller wallet execution capability' is vague—unclear whether it checks funds, permissions, or other conditions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
