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. While 'Archive (delete)' implies a destructive operation, it doesn't clarify whether this is reversible, what permissions are required, whether it's a soft or hard delete, or what happens to associated data. For a destructive operation with zero annotation coverage, this is inadequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
