Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must fully disclose behavioral traits. It only states 'Fetch' implying a read operation, but does not confirm idempotency, data source (Dritan's role), or any side effects. This is insufficient for an agent to assess safety or expect return behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
