Reconstructing the agent methodology: Decoupling decision-making and execution - open source [P]

I’ve been thinking about a problem in current agent systems: Most agents are becoming very good at execution, but the decision layer before execution is still unclear. Coding agents, research agents, tool loops, sandboxes, workflows, and harnesses are all improving quickly. Once a human gives an intent, agents can often do a lot of useful work. But the higher-level question is still usually left to the user: What should happen next, and why? I’ve been exploring this idea through an open-source project called Spice. The simplest way to describe it is: Spice is a decision layer above agents.
