Cascade-Aware Multi-Agent Routing: Failure Propagation Differs Between Tree and Cyclic Agent Execution Graphs

arXiv·low signal

ArXiv paper 2603.17112 models how error cascades propagate differently in tree-shaped vs. cyclic agent execution graphs, finding that cyclic graphs amplify failures non-linearly while tree graphs bound them structurally. The practical implication: agent orchestration architectures should default to tree-shaped execution topologies when reliability is a constraint, reserving cycles only for explicit convergence requirements. Timing is relevant as multi-agent orchestration frameworks (LangGraph, Mastra) default to cyclic graphs.
