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. It does disclose one useful trait – that deletion cascades to 'its edges' – but says nothing about irreversibility, required permissions, whether the node must exist, or what is returned on success/failure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
