Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the transparency burden. The verb 'retrieve' conveys a read-only intent, and the description lists what data is included, but it does not disclose potential errors, authentication requirements, or return format. For a simple read operation, this is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
