arXiv:2604. 15267v2 Announce Type: replace-cross Abstract: It is increasingly important that LLM agents interact effectively and safely with other goal-pursuing agents, yet, recent works report the opposite trend: LLMs with stronger reasoning capabilities behave _less_ cooperatively in mixed-motive games such as the prisoner's dilemma and public goods settings.

arXiv:2608. 14613v1 Announce Type: new Abstract: Modern LLM-agent frameworks increasingly interoperate through standards such as Anthropic's Model Context Protocol (MCP) for agent-to-tool access and Google's Agent2Agent (A2A) protocol for agent delegation and negotiation.

The paper "Can LLMs Trust Appropriately? Evaluating Calibrated Reliance on Imperfect Partners" introduces a benchmark of 324 scenarios across 23 collaboration categories to test how well large language models translate partner evidence into calibrated trust decisions. Each scenario requires three sequential decisions with defined transition dynamics, feedback, and cost schedules, allowing precise analytical evaluation of choices against expected outcomes. The study evaluates seven models and 36 controlled-history probes, finding that while the best frontier model approaches near‑optimal decisions, other models display pathologies such as excessive safeguards, zero‑value verification purchases, prioritizing immediate savings over cooperative learning, and misallocating assistance.

MiniRep is a reputation‑based aggregation system designed for multi‑agent debate (MAD) that remains robust even when malicious agents are present. It evaluates agents on both their current task performance and historical reputation, while preventing groups of agents with highly similar responses from dominating the final decision. Experiments on the MATH benchmark show that MiniRep consistently outperforms conventional MAD aggregation and other reputation‑based approaches across a wide range of attack scenarios.
