Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral traits. It states it reads settings (implying non-destructive), but does not disclose other relevant behaviors such as authentication requirements, rate limits, error handling, or what happens when invalid keys are provided. The description is minimal and lacks depth.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
