Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must disclose behavior fully. It only states the tool generates a handover sheet, but omits critical details: whether it creates a new sheet, appends to existing data, requires authentication, or what the output format is. This lack of transparency leaves the agent uncertain about side effects and return values.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
