Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden of disclosing behavior. The only disclosed trait is the $0.001 USDC cost; nothing about what the tool does, what inputs it expects, whether it mutates state, or what it returns. This leaves the agent completely in the dark.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
