Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must convey behavioral traits. It states the operation is destructive ('DELETE') and requires user confirmation, which is key. However, it omits details about irreversibility, effects on related data, or any permissions required.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
