Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnlyHint=true, and the description adds behavioral context by explaining that this tool tracks the creator-ingest job, not individual post analysis. It does not contradict annotations. It could mention response format or polling behavior, but the existing description is strong.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
