Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden. It mentions 'terminate script execution immediately', which hints at destructive behavior, but lacks details on permissions needed, irreversible effects, error conditions, or what happens to session data. For a potentially destructive tool, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
