Report #91309

[frontier] Static graph edges prevent agents from dynamically routing to specific peers based on runtime context

Return Command objects from node functions with goto and update parameters to imperatively route to specific agents while updating state

Journey Context:
Traditional LangGraph requires defining all possible edges at build time, or using conditional edge functions that check state with complex lambdas. The Command primitive \(introduced 2025\) allows nodes to emit routing decisions dynamically: return Command\(goto='code\_review\_agent', update=\{'assigned\_to': 'reviewer\_1'\}\). This enables emergent workflows where the graph topology is determined at runtime by the agents themselves, not the developer. Unlike static supervisors, this allows dynamic load balancing and capability-based routing.
