Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the transparency burden. It discloses the return payload (wallet address, fee format, specialties, SLA, health status, dispute track record) and the lack of authentication. While it doesn't explicitly state that the operation is read-only or non-destructive, 'Browse' implies such, and the detail about fee basis points adds valuable context. Slightly more could be said about output ordering or pagination, but the provided info is substantial.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
