Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description gives no behavioral details. It does not disclose whether the tool is destructive, requires specific permissions, has side effects, or what the return value is. For a tool with no annotations, the description carries the full burden of transparency and fails completely.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
