Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden. It does add real value by disclosing the superuser-only authorization requirement and the Langflow 1.12.x version constraint, and 'Read' signals a non-mutating operation. It says nothing about the returned bundle's contents, whether it reflects the active or pending policy, or any pagination/error behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
