OctoNest: Adaptive Cross-Device Execution through Stateful Control
OctoNest introduces HRePlan, a hierarchical replanning framework for multi-device agents to handle failures robustly across different environments. It separates local device strategy recovery from global orchestrator replanning using a compact failure abstraction (CLFE). This allows agents to distinguish between simple fixes and complex cross-device repairs, significantly boosting task completion rates and reducing token costs in complex workflows.
