Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states the action is destructive ('archive/delete'), which is helpful, but lacks critical details like whether archiving is permanent or reversible, what permissions are required, if there are rate limits for batch operations, or what happens if some IDs fail. This leaves significant gaps for a destructive batch operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
