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 states the action is 'permanently delete', which implies destructive and irreversible behavior, but doesn't cover permissions required, error conditions (e.g., if the list doesn't exist), or what happens to associated data. This is a significant gap 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.
