Beyond Semantic Organization: Memory as Execution State Management for Long-Horizon Agents

arXiv:2606.06090v1 Announce Type: new Abstract: LLM-based agents increasingly tackle long-horizon tasks with interdependent decisions, where each action reshapes future constraints and intermediate errors can cascade. Existing RAG and agent memory systems organize histories by semantic similarity, retrieving content-relevant entries at decision time. We argue that this design mismatches execution-state dependencies: it fragments decision trajectories and mixes valid and erroneous traces, hindering coherent state reconstruction and error isolation. We propose MAGE (Memory as Agent-Guided Explor

Why this matters
Why now

The increasing complexity of LLM-based agent tasks necessitates more sophisticated memory management to overcome limitations of current semantic retrieval systems.

Why it’s important

Improving memory and execution state management is critical for agents to achieve long-horizon goals and operate autonomously without cascading errors.

What changes

This research proposes a new paradigm for agent memory that moves beyond semantic similarity to focus on execution state, allowing for more coherent decision-making and error recovery.

Second-order effects
Direct

Agents will be able to perform more complex, multi-step tasks with greater reliability and less human intervention.

Second

This could accelerate the deployment of autonomous systems in critical applications and industries requiring long-term planning.

Third

More robust agentic capabilities may lead to new economic models and workflow automation beyond current predictions.
