Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so the description carries the full burden. It doesn't state whether deletion is permanent or reversible, whether it requires specific permissions, what happens to referenced content, or what the return value is. 'Delete' implies destruction but nothing beyond that is disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
