Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so the description carries the burden. It explicitly states 'Read-only' and 'Recomputable from public chain data + the public mandate', disclosing that it is a deterministic read operation. It does not cover error handling or rate limits, but the core behavioral trait is disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
