Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It accurately describes the read-only nature of listing forms and the expected output, though it could explicitly state it is non-destructive or mention any authentication requirements. Overall, it is transparent for a simple list tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
