Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden but provides minimal behavioral insight. It states permanence, hinting at irreversibility, but lacks details on permissions, side effects (e.g., impact on leads or analytics), error conditions, or confirmation requirements. This is inadequate for a destructive operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
