Enforcing Benign Trajectories: A Behavioral Firewall for Structured-Workflow AI Agents
arXiv CS.AI

ArXi:2604.26274v1 Announce Type: cross Structured-workflow agents driven by large language models execute tool calls against sensitive external environments. We propose \codename, a telemetry-driven behavioral anomaly detection firewall. Drawing on sequence-based intrusion detection, \codename\ compiles verified benign tool-call telemetry into a parameterized deterministic finite automaton (pDFA). The model defines permitted tool sequences, sequential contexts, and parameter bounds.
