Title: Formal Skill: Programmable Runtime Skills for Efficient and Accurate LLM AgentsSource: http://arxiv.org/abs/2605.19604v1Summary:This work introduces a foundational architectural primitive for agents that replaces informal natural-language instructions with programmable, stateful runtime skills governed by hook policies and action schemas. This shift from prompting to executable state machines provides a more enforceable and token-efficient control surface for reliable agentic workflows in real-world environments.
