Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already establish read-only, idempotent, non-destructive behavior. The description adds beyond those by explaining wait polling, terminal status names, and the instruction to follow llmContext guidance within results. This is meaningful behavioral context not encoded in the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
