Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. 'Permanently delete' implies a destructive, irreversible operation, which is critical context. However, it lacks details on permissions, side effects (e.g., impact on related transactions), error conditions, or confirmation requirements, which are important for a destructive tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
