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 helpful, but doesn't mention whether archiving is reversible, what permissions are required, whether there are rate limits, or what happens to archived tasks. For a batch destructive operation, this leaves significant behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
