WHAT IT DOES

What nb_open_delegation does on Nodebench

AI agents call nb_open_delegation to retrieve information from Nodebench without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why nb_open_delegation is rated Low

The description says 'review' which implies reading/querying delegation and authority configurations. 'Open' in this context appears to mean opening a view or surface for inspection rather than executing or modifying anything. However, confidence is moderate since the description is vague and 'approval gates' could imply triggering workflows.
