Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description transparently describes the output format (txid, date/time, amount in satoshis), chronological ordering, string representation, and address format acceptance. It does not mention rate limits or authentication, but as a read-only history tool, the behavioral disclosure is adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
