Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds the behavioral trait 'cached', indicating the artifact is pre-generated rather than computed on demand. This goes beyond the annotations, which only declare readOnly, idempotent, and non-destructive hints. No negative traits are disclosed but none are needed given the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
