摘要

Cooperative multi-objective multi-agent reinforcement learning (MOMARL) models team decision making under multiple, potentially conflicting objectives. In this setting, conflicts arise not only across objectives but also across agents with different observations, roles, and contributions. We propose Preference Coordinated Multi-agent Policy Optimization (PCMA), which learns coordinated agent-specific preferences to enable complementary trade-offs among agents. Theoretically, we formulate cooperative MOMARL as a team-optimal game and show that, under suitable conditions, preference diversity can induce team improvement through a first-order improvement decomposition. Experiments on multiple cooperative MOMA environments and a practical traffic-control scenario show that PCMA improves both performance and trade-off coordination.

一句话结论

AgentSpec通过标准化接口和模块化设计，揭示了具身代理性能由组件交互效应而非孤立模块强度决定。

核心内容

AgentSpec将具身代理表示为可重用策略组件的类型化组合，标准化感知、记忆、推理、反思、动作及学习接口，支持组件交换重组。
实验发现：结构化多粒度记忆提升长周期状态跟踪，推理与记忆交互不均匀，反思在修正与成本间权衡。
代理性能由支架兼容性与交互效应主导，而非单个模块强度；RL策略需优化部署时支架结构以最佳组合。

方法与数据

在DeliveryBench、ALFRED、MiniGrid和RoboTHOR上实例化框架，分析推理、记忆、反思和强化学习模块交互。
摘要未明确具体数据集细节。

价值判断

值得关注：为研究、比较和设计可组合LLM代理提供受控实验基础。
可复用点：标准化接口支持策略组件在受控条件下交换重组，便于快速迭代设计。
局限/待核查：摘要未明确。

摘要

LLM agents are increasingly built not as single model calls, but as scaffolded systems that combine reasoning, memory, reflection, action execution, and learning. While such scaffolds often improve performance, they are often embedded in tightly coupled pipelines, making it difficult to isolate component contributions, compare alternative designs, or understand how module interactions shape agent behavior. We introduce AgentSpec, a modular specification framework that represents embodied agents as typed compositions of reusable policy components with standardized interfaces. AgentSpec standardizes the interfaces among perception, memory, reasoning, reflection, action, and optional learning, enabling components to be swapped and recombined under controlled conditions. We instantiate this framework across DeliveryBench, ALFRED, MiniGrid, and RoboTHOR, and analyze reasoning, memory, reflection, and reinforcement-learning modules across model backbones. Our results show that agent performance is governed by scaffold compatibility and interaction effects rather than isolated module strength. In particular, structured multi-granularity memory improves long-horizon state tracking, reasoning and memory interact non-uniformly across environments, reflection trades off correction and cost, and RL-trained policies compose best when optimized with deployment-time scaffold structure. AgentSpec provides a controlled foundation for studying, comparing, and designing composable LLM agents. Our code, baselines and interactive playground are publicly available at https://agentspec-embodied.github.io.
