Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively communicates that the action is destructive ('Delete') and irreversible ('This cannot be undone'), which are critical traits for a mutation tool. However, it doesn't mention potential side effects, error conditions, or authentication requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
