Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It reveals that results include both sent and received transfers, are sorted newest-first, and are restricted to EVM chains with a data-capable upstream. It does not mention pagination or result limits, but the disclosed behaviors are meaningful and accurate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
