Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must convey the tool's behavior. It indicates a read operation via 'Get,' but it does not disclose error behavior for nonexistent IDs, authentication requirements, or what is included in 'details.' This is a basic level of transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
