Utility Skill Overview A decision framework for agent orchestration based on Liu et al., "Utility-Guided Agent Orchestration for Efficient LLM Tool Use" (arXiv:2603.19896). Each candidate action is scored by subtracting weighted costs from expected gain, producing a single utility value that guides action selection. The framework prevents over-calling tools and premature stopping by making both errors costly. Utility range is [-2.3, 1.0]. When To Use - Deciding whether to dispatch another agent or tool call - Gating expensive tool calls (search, code execution, delegation) - Selecting the rig…
