Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so description must disclose behavior. It only says 'Get details', which implies read-only but omits what details are returned, whether authentication/project access is required, or error behavior for missing upload. Under-specified for a get operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
