Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, and the description reinforces read-only behavior. It adds useful behavioral detail beyond annotations: results include status, prompt, render existence, and are ordered newest first. This is enough transparency for a non-destructive list operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
