Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate the tool is non-read-only, non-idempotent, and non-destructive. The description adds the endpoint and chat_complete behavior, but does not disclose additional side-effect risks, rate limits, or stream consumption details. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
