Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden. 'Get' implies a read, but it says nothing about permissions, behavior for an unknown ID, size/pagination of the returned tree, or whether nodes and links are both included in 'full data'.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
