Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must fully disclose behavior. It states 'Get detailed information', which implies a read-only operation, but does not specify what fields are returned (e.g., position, size, net). This is minimally adequate for a simple read tool but lacks detail.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
