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)' clearly indicates a destructive operation, the description doesn't specify whether this is reversible, what permissions are required, whether there are rate limits, or what happens to associated data. For a destructive tool 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.
