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 archives/deletes emails, indicating a destructive mutation, but lacks details on permissions required, whether deletion is permanent or reversible, rate limits, or response format. This is inadequate for a destructive operation with zero annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
