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 indicates this is a destructive operation ('archive (delete)'), which is useful, but doesn't mention permissions required, whether archiving is reversible, what happens to associated data, or any rate limits. For a destructive tool with zero annotation coverage, this leaves significant gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
