Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must convey behavioral traits like mutability, idempotency, permissions, or side effects. The description only repeats the name and endpoint, offering no insight into whether tags are appended or overwritten, or what happens if recipes or tags are invalid.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
