Goal In, DAG Out: How Open-Multi-Agent Turns a Goal into a Task DAG

You wrote the graph by hand. Then the requirements changed. Most TypeScript agent frameworks make you draw the graph yourself. You declare the nodes, wire the edges, decide what runs after what, where it branches, where it joins. It works, right up until the goal shifts and you are back in the graph editor re-wiring a pipeline you already built once. There is another way to model this: describe the goal, and let a coordinator build the graph for you. That is what runTeam() does in open-multi-agent. You hand it a team and a sentence. It hands back a result. In between, a coordinator agent decomposes the goal into a task DAG, assigns the tasks to your agents, runs the independent ones in parallel, and synthesizes the final answer. There are no edges to wire. This post is about what happens in that "in between," because the mechanism is the whole point. The one call import { OpenMultiAgent } from ' @open-multi-agent/core ' const orchestrator = new OpenMultiAgent ({ defaultModel : ' deepseek-v4-flash ' , defaultProvider : ' deepseek ' , }) const team = orchestrator . createTeam ( ' research ' , { name : ' research ' , agents : [ { name : ' researcher ' , model : ' deepseek-v4-flash ' , provider : ' deepseek ' , systemPrompt : ' You research topics and gather concrete facts. ' }, { name : ' writer ' , model : ' deepseek-v4-flash ' , provider : ' deepseek ' , systemPrompt : ' You turn research notes into clear prose. ' }, ], sharedMemory : true , }) const result = await orchestrator . runTeam ( team , ' Research the tradeoffs of TypeScript decorators, covering the stage-3 standard ' + ' versus the legacy experimental implementation, runtime and bundle-size cost, and ' + ' current framework support, then write a clear 500-word explainer for a team ' + ' deciding whether to adopt them. ' , ) console . log ( result . agentResults . get ( ' coordinator ' )?. output ) Three things to notice before we go under the hood: You never declared a task graph. You wrote the goal in pla
