Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the full burden of behavioral disclosure. It only states 'Get details,' implying a read operation, but does not disclose what response format to expect, whether special permissions are needed, or behavior when the guest is not found. This is a notable gap even for a simple get.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
