Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states the tool purges data, which implies destructive behavior, but does not disclose reversibility, required permissions, or any safety mechanisms. The specifics of what is purged are listed, but deeper behavioral context is missing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
