Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the full behavioral burden. It only states what the tool does, not how it behaves—such as whether it waits for a dialog, what happens if no dialog appears, or how the timeout affects execution. This is too thin for a tool with zero annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
