SAFARI: Scaling Long Horizon Agentic Fault Attribution via Active Investigation

arXiv:2606.24626v1 Announce Type: new Abstract: As autonomous agents tackle increasingly complex multi-step, multi-agent tasks, their execution trajectories have scaled beyond the constraints of even the largest context windows. Current methods for effectively diagnosing agent failures load the full trajectory into an LLM's context window, which suffers from attention dilution and fails when agentic traces inevitably exceed context limits. To address this, we introduce SAFARI (Scaling long-horizon Agentic Fault AttRibution via active Investigation), a framework that replaces linear context loa

Why this matters
Why now

As autonomous agents become increasingly complex and handle longer tasks, the current methods for fault diagnosis are hitting critical context window limitations, making new solutions like SAFARI necessary.

Why it’s important

This development addresses a core technical bottleneck for scaling agentic AI, which is crucial for their reliable performance in real-world applications.

What changes

The ability to attribute faults in long-horizon agent trajectories without prohibitive computational cost and attention dilution opens the door to more robust and scalable AI agents.
