Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds no behavioral context beyond the annotations. It doesn't mention return behavior, idempotency implications (despite idempotentHint=true), or requirements. With annotations already indicating a write operation, the description provides no additional transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
