Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It does disclose the important cascade behavior ('and all its nodes'), which is genuine context beyond the name, but it omits whether the deletion is permanent, whether confirmation or elevated permissions are needed, and what happens to linked or referenced data.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
