Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It discloses that deletion is irreversible, which is a critical behavioral trait. However, it does not mention side effects on associated data, required permissions, or whether it is a hard or soft delete, leaving notable gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
