Beyond Global Replanning: Hierarchical Recovery for Cross-Device Agent Systems

arXiv:2606.20487v1 Announce Type: new Abstract: Real-world computer-use tasks often span multiple applications and devices, requiring agents to coordinate heterogeneous environments under dynamic runtime failures. Existing multi-device agent systems support task decomposition and cross-device assignment, but recovery remains largely coarse-grained: when execution fails, they typically retry the same strategy, reassign the subtask, or revise the global plan, without systematically modeling the device-local strategy space. This limits their ability to distinguish failures that can be repaired wi

Why this matters
Why now

The paper addresses a critical limitation in current multi-device agent systems, proposing advanced recovery mechanisms essential for robust real-world deployment as these systems mature.

Why it’s important

Improving the resilience and fault tolerance of multi-device AI agents is crucial for their broader adoption and for handling complex, real-world tasks across diverse computing environments.

What changes

Current agent systems' recovery mechanisms are largely coarse-grained; this research introduces hierarchical recovery, allowing for finer-grained, more effective failure handling at the device-local level.

Winners
  • · AI agent developers
  • · Cross-device computing platforms
  • · Enterprises adopting AI-driven automation
Losers
  • · Systems with simplistic agent recovery (eventual obsolescence)
  • · Manual IT task management
Second-order effects
Direct

More reliable and capable AI agents emerge for complex, real-world tasks involving multiple devices and applications.

Second

Increased trust and adoption of AI agent systems in critical enterprise and consumer workflows due to reduced failure rates.

Third

The development of standardized protocols and frameworks for hierarchical error recovery in distributed AI systems becomes a new area of industry focus.
