Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden for behavioral disclosure. It explicitly warns that the action cannot be undone, which is a critical behavioral trait for a delete operation. However, it does not mention other potential side effects or permission requirements, though the irreversibility warning is strong.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
