Experimenting with a multi-agent system without leaders or messaging

I’ve been experimenting with a multi-agent orchestration model designed by my agent. The core concept is a WorkItem DAG — basically an ordered dependency graph similar to a structured todo list. \- A Planner generates the execution DAG \- Worker agents execute work items mechanically along the graph \- If unexpected situations happen, a RePlanner patches the DAG and creates a new execution path So agents themselves are intentionally “dumb”. Most of the intelligence is concentrated in planning and replanning. This feels very different from most current multi-agent architectures I’ve seen. I’m currently building this system based mostly on intuition, and honestly I’m not even sure whether this architecture will actually work well in practice. I’m curious: Has anyone here experimented with similar DAG-based orchestration models? How did they perform compared to message-passing systems? Are there good benchmarks or evaluation methods for testing whether this kind of architecture is actually effective? Would love to hear thoughts or related papers/projects.
