The owners don't win by having a lockout. Shutting down your business is not good for anybody and it's certainly not good for the players, it's certainly not good for the fans. And that's most important to us. — Roger Goodell 36 items · 3 sections

MemHarness: Memory Is Reconstructed, Not Replayed

Rong Wu, Daocheng Fu, Licheng Wen, Xuemeng Yang, Shu Zou

emHarness proposes a novel approach to memory augmentation for LLM agents, moving beyond simple verbatim replay. Its core method involves a unified policy model that actively reconstructs retrieved past experiences based on the agent's current state. This allows agents to adapt and ground memories in the present context, mitigating negative transfer and improving decision-making.

Memory utilization paradigms. Top: Prior methods directly replay retrieved memories, risking state misalignment. Middle: Human memory reconstructs past experience according to the current context. Bottom: Inspired by this process, MemHarness reconstructs retrieved memories into state-aligned guidance.

One Human, $N$ Agents: Audit-Budget Allocation for LLM Agent Fleets under Miscalibrated, Correlated Confidence

Cesare Zavattari, Alessandro Tommasi et al.

This paper addresses the challenge of a human auditor allocating a limited budget to audit a fleet of $N$ LLM agents, whose self-reported confidence is unreliable due to miscalibration and correlated errors. The core method models this as budgeted noisy inspec…

ORCA-bench: How Ready Are Language Model Agents for Oncall?

Albert Gong, Kyuseong Choi et al.

This paper introduces ORCA-bench, a novel benchmark designed to evaluate the readiness of language model agents for on-call incident response. The benchmark simulates a production-fidelity microservice environment with real telemetry data and source code, pres…

RCA accuracy measures whether agents identified all plausible root causes, and hallucination rate measures whether agents named a root cause matching none of the plausible root causes. We show the realistic Medium and Hard difficulties here and report Easy in Fig. ˜ 5 along with Claude Fable 5 results on a subset of tasks in Sec. ˜ 5 . Error bars display ± 1 \( \pm \) 1 standard error across 884 incident tasks.
