Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare this is not read-only and not idempotent. The description adds the fact it uses POST and is streaming, yielding instruction output. However, it does not explain behavior around cancellation, state persistence, or open-world effects beyond the annotation hints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
