Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden and does so well. It discloses authentication requirements, the polling nature, retry behavior when is_done=false, and the returned fields (is_done, vetting_status, findings). It also notes the 'official recommended path' and uploader-only access with API key, adding meaningful behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
