- AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
- agent skill — A reusable instruction file that teaches an agent how to do one job well — the procedure, the tools, and what counts as done.
design is usually argued on capability; this puts a cost frame on it and gives a concrete reason to prefer program-shaped skills over prose ones in long-horizon agents.
“We argue that among all the different skill learning methods, those that view skills as programs can achieve the best cost reduction.”
Zixi Huang et al.
“By executing sequences of actions deterministically, a program-augmented agent can reliably and cheaply achieve goals that would otherwise require trial and error and risk degenerate behavior over long horizons.”
Zixi Huang et al.
“We hypothesize that past trajectories contain enough signal to guide skill learning, even without replay or validation, provided the agent can learn to analyze them.”
Zixi Huang et al.
“Across three different embodied environments, we show that SpeedRunner consistently achieves the frontier in learning and cost reduction while remaining robust against distribution shifts and environmental randomness.”
