SRE-Marathon: A Continuous, Change-Driven Benchmark for Autonomous Site Reliability Agents

This work presents SRE-Marathon, a benchmark for long-horizon, continuous SRE operation, where an agent is invoked at a fixed cadence with cumulative alert history and a persistent workspace while operating a live two-zone Kubernetes deployment as a fault orchestrator injects overlapping faults according to a seeded, p...

ORCA: Observability-Grounded Program Repair for Microservice Incidents

Results show that operational telemetry can be transformed from diagnostic evidence into actionable repair context: paired telemetry supports repair-oriented localization, while repair graph agents convert localized code and configuration evidence into constrained patch-generation context for the LLM.

When Agentic Executions Fail: Detecting and Localizing Runtime Faults from Telemetry

AGENTCHAOSBENCH is presented, a benchmark for detecting and localizing runtime faults in agentic systems from their execution telemetry, and its held-out labels and compact prediction format support reproducible comparison of LLM-based and non-LLM diagnosis methods.
