eARCO is a novel framework that leverages Large Language Models to automate and optimize root cause analysis for cloud system incidents.

• Reduces manual effort required from on-call engineers during incident resolution
• Employs prompt optimization techniques to improve LLM accuracy for technical troubleshooting
• Accelerates incident resolution and reduces service downtime
• Creates a more efficient, knowledge-driven approach to root cause analysis

Security Impact: By streamlining incident response, eARCO enhances security operations' ability to quickly identify and address potential security incidents, minimizing vulnerability windows and improving overall system resilience.
