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 correctly indicates this is a destructive operation ('Archive (delete)'), but fails to mention critical behavioral aspects like whether archiving is reversible, what permissions are required, whether there are rate limits, what happens to associated data, or what the response format looks like. For a destructive batch operation with zero annotation coverage, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
