Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. 'Returns' implies a safe, read-only operation and 'ready-to-paste' adds useful output-format context. However, it does not disclose auth requirements, error behavior, or output structure in a way that fully compensates for the missing annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
