Do Agents Know What They Can't Do? Evaluating Feasibility Awareness in Tool-Using Agents

ArXi:2605.28532v1 Announce Type: new Tool-using agents often incur substantial computational cost due to long reasoning chains and iterative tool usage. In practical scenarios, many tasks become infeasible under constrained tool environments, where the capabilities required for successful task completion are unavailable. Detecting infeasible tasks and stopping execution early can significantly reduce unnecessary execution cost.
