From Noisy Traces to Root Causes: Structural Trajectory Analysis and Causal Extraction for Agent Optimization
arXiv:2607.07702v1 Announce Type: new Abstract: The optimization of long-horizon agents increasingly relies on reflection-based mechanisms, where a large language model (LLM) acts as an optimizer to diagnose agent failures and improve agent policies. However, real execution traces are difficult to use directly for optimization: large trace collections are often redundant and heterogeneous, making optimization inefficient and prone to overfitting to low-value failures; meanwhile, each individual trajectory also contains many irrelevant steps, while naive context reduction methods such as trunca
The increasing complexity of long-horizon AI agents and the limitations of current reflection-based optimization methods necessitate more sophisticated techniques for identifying and diagnosing failures from execution traces.
Improving the efficiency and efficacy of AI agent optimization is crucial for developing robust, scalable, and autonomous systems capable of complex tasks, impacting a wide range of industries.
The ability to accurately extract root causes from noisy agent traces will significantly accelerate the development and deployment of reliable AI agents, moving beyond manual or inefficient diagnostic processes.

More capable and reliable AI agents will emerge, reducing the need for human intervention in complex tasks.
The accelerated development of autonomous AI systems will drive productivity gains across multiple sectors, potentially displacing certain white-collar roles.
The enhanced autonomy could lead to AI agents optimizing entire systems or supply chains, creating new forms of economic value and potentially new risks of systemic failure if not properly controlled.
