Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It states the operation is a get (read), but doesn't disclose what the response contains, whether the policy is account-wide or mailbox-specific, or any authentication requirements beyond the implied apiKey parameter. The description is minimal and doesn't add behavioral context beyond the obvious read operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
