Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the burden of behavioral disclosure. It does disclose the routing behavior (block identifiers use /v1/blocks, etc.) and hints that pool names must be 'known' and addresses are 'candidate payout addresses'. However, it does not disclose whether exactly one parameter must be provided, how conflicts are handled, or any failure modes. This is a moderate level of transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
