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. It states the action is 'archive (delete)', implying a destructive operation, but doesn't specify whether this is permanent or reversible, what permissions are required, rate limits, or what happens to associated data. For a destructive batch operation, this leaves critical gaps in understanding the tool's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
