Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the disclosure burden. The verb 'Retrieve' indicates a read-only operation, and 'passed resolutions' implies stable, official data. It adds contextual behavior by describing these as 'the living record' and 'the rules we compute by,' but it does not explicitly state side-effect-free behavior, auth requirements, or return format details.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
