Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description is a bare phrase. It discloses nothing about side effects, read-only nature, data returned, or failure modes. For a tool with no annotations, the description carries the full burden, and it completely fails to do so.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
