AgentFactory: Towards Automated Agentic System Design and Optimization\u003c/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAbstract\u003c/strong\u003e: Large Language Models (LLMs) have demonstrated remarkable capabilities as powerful components in agentic systems, enabling sophisticated reasoning and complex task execution. However, current approaches to manually designing and optimizing agentic systems heavily rely on manual effort, limiting their adaptability and scalability. Recent work has explored the automated optimization of workflow designs. However, these approaches often overlook the crucial role of model capabilities and focus on single performance metrics, failing to address real-world deployment constraints. In this paper, we present AgentFactory, a framework that jointly optimizes both foundation models and workflow structures in agentic systems while considering multiple objectives including performance, cost, and efficiency. AgentFactory leverages advanced LLMs as optimizers to navigate the vast search space of possible configurations, employing a three-stage optimization pipeline to automatically discover effective combinations of fine-tuned models and optimized workflows. Through an iterative optimization process, our framework systematically explores and evaluates different agentic system designs, adapting to task-specific requirements while maintaining operational efficiency. We evaluate AgentFactory across eight benchmarks spanning five domains, including general reasoning, coding, mathematics, medicine, and finance. Our experiments demonstrate that AgentFactory consistently outperforms both manually designed methods and existing automated approaches, achieving an average improvement of 9.1% across all benchmarks, with particularly significant gains in domain-specific tasks (19.6% on MedQA and 18.7% on FinEval). These results establish AgentFactory as a promising approach for developing more capable and efficient agentic systems through automated optimization.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eDomain\u003c/strong\u003e: Agent system design / Automated optimization (cs.AI)\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy it matters\u003c/strong\u003e: Treating \u0026ldquo;model selection + workflow design\u0026rdquo; as one searchable configuration space with an LLM as optimizer, averaging +9.1% across 8 benchmarks and up to +19.6% in vertical domains — a direct answer to the engineering pain that manually stacking agents doesn\u0026rsquo;t scale.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eLink\u003c/strong\u003e: \u003ca href=\"https://arxiv.org/abs/2609.01045\"\u003ehttps://arxiv.org/abs/2609.01045\u003c/a\u003e\u003c/p\u003e\n\u003ch3 id=\"2-pgpo-potential-guided-policy-optimization-for-multi-turn-agentic-tasks\"\u003e2. PGPO: Potential-Guided Policy Optimization for Multi-Turn Agentic Tasks\u003c/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAbstract\u003c/strong\u003e: Group-based reinforcement learning (RL) has become an effective paradigm for LLM post-training, but in multi-turn agentic tasks with sparse terminal rewards, it often provides coarse credit for intermediate actions. To obtain more fine-grained credit assignment, recent work such as GiGPO introduces step-level advantages for intermediate actions. However, these step-level signals still rely on the final outcome of each individual trajectory. As a result, actions within failed trajectories can remain poorly differentiated, so effective actions can receive the same unfavorable credit as erroneous ones. In this work, we propose Potential-Guided Policy Optimization (PGPO) for multi-turn agentic tasks. PGPO estimates empirical state potentials from anchor-state-group return statistics within each rollout group. It then derives action advantages from potential differences between adjacent states, enabling cross-trajectory credit propagation. This provides finer-grained step-level credit assignment, especially within failed trajectories. Experiments on ALFWorld and WebShop show strong overall performance relative to recent group-based RL methods. Further analysis provides evidence that PGPO yields more informative failure-side credit signals with negligible training overhead.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eDomain\u003c/strong\u003e: Reinforcement learning / Multi-turn agent training (cs.AI)\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy it matters\u003c/strong\u003e: Targets the hard defect that \u0026ldquo;in failed trajectories good and bad actions get equally poor credit\u0026rdquo;, using state-potential differences for cross-trajectory credit assignment at near-zero training overhead — a low-cost, copyable improvement for teams doing agent post-training.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eLink\u003c/strong\u003e: \u003ca href=\"https://arxiv.org/abs/2609.02236\"\u003ehttps://arxiv.org/abs/2609.02236\u003c/a\u003e\u003c/p\u003e\n\u003ch3 id=\"3-uncovering-understanding-generation-synergy-in-native-unified-multimodal-models-from-representation-task-to-system\"\u003e3. Uncovering Understanding-Generation Synergy in Native Unified Multimodal Models: From Representation, Task to System\u003c/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAbstract\u003c/strong\u003e: While unified multimodal models (UMMs) jointly perform visual understanding and generation within a single model, functional unification does not guarantee learning synergy: the two objectives may reinforce each other, compete for capacity, or merely coexist. We investigate their relationship at the representation, task, and system levels in a controlled, structurally native setting without pretrained vision priors. At the representation level, we find that each objective provides useful signal to the other: generation enriches the visual features learned for understanding, while understanding strengthens vision–language alignment for generation. However, when both objectives are forced through the same computation path, one tends to dominate. A task-decoupled architecture that specializes conflicting visual computation while preserving semantic interaction avoids this asymmetric degradation. At the task level, through three case studies, we find positive bidirectional transfer when understanding and generation tasks rely on shared knowledge. At the system level, we show that an end-to-end UMM outperforms a matched planner–executor pipeline on complex tasks that explicitly require both image understanding and generation. Together, these results show that the value of UMMs extends beyond a unified interface: appropriate specialization, shared task knowledge, and end-to-end optimization can turn coexistence into synergy.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eDomain\u003c/strong\u003e: Unified multimodal models / Visual understanding and generation (cs.CV)\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy it matters\u003c/strong\u003e: Systematically decomposes whether \u0026ldquo;understanding\u0026rdquo; and \u0026ldquo;generation\u0026rdquo; reinforce each other or compete for capacity, in a controlled setting without pretrained vision priors, and gives deployable task-decoupled architecture advice — valuable reference for teams building unified multimodal models.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eLink\u003c/strong\u003e: \u003ca href=\"https://arxiv.org/abs/2609.01607\"\u003ehttps://arxiv.org/abs/2609.01607\u003c/a\u003e\u003c/p\u003e\n\u003ch3 id=\"4-efficient-swe-agent-benchmarking-via-trajectory-aware-evaluation\"\u003e4. Efficient SWE Agent Benchmarking via Trajectory-Aware Evaluation\u003c/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAbstract\u003c/strong\u003e: Evaluating software engineering agents on realistic benchmarks is costly, since each task may require multi-step code exploration, modification, and test execution. Existing efficient evaluation methods select representative subsets to estimate full-benchmark performance, but are largely result-only: they fit historical pass/fail response matrices or static task semantics, discarding how agents solve problems. We propose PTA-IRT, a Privileged Trajectory-Aware Item Response Theory framework that fuses process and outcome signals. Historical execution trajectories supply process-level evidence beyond pass/fail, such as explored context, attempted edits, and solving paths, which PTA-IRT uses as privileged information for calibration subset selection and ability estimation. Under low calibration budgets, PTA-IRT consistently outperformed prior IRT baselines on score and ranking recovery across four SWE benchmarks.

CordisBench: Can Language Models Reason About Component Lifecycles in Dynamic Agent Harnesses?\u003c/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAbstract\u003c/strong\u003e: Dynamic agent harnesses let language models change the software that shapes their own execution. This flexibility brings a new reasoning burden: a local plugin change can propagate through dependencies and cleanup. We introduce CordisBench, a 1,200-question benchmark of this lifecycle reasoning. It combines a controlled formal setting with programs executed against Cordis, a runtime that manages component dependencies and cleanup, and asks models to identify affected components, predict state after a specified teardown order, determine which conditions hold under all or some orders, and choose reconfigurations that succeed when executed. Across these tasks, we evaluate three efficiency-oriented models at low reasoning effort with 2, 4, 8, 16, 24, or 32 relevant interactions, using deterministic task-specific scoring. Models usually handle small systems well but grow less reliable as more interactions become relevant, especially when predicting final state and when reasoning across teardown orders. Additional inference effort recovers marked gains for some models. The cost is nontrivial: on our 16-interaction subset, GPT-5.6 Luna uses nearly 3,000 reasoning tokens per question at medium effort. For these controlled instances, that cost is avoidable: an independent finite reference semantics agrees with Cordis execution on every observation and action outcome used for scoring across all 528 executable questions.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eDomain\u003c/strong\u003e: Dynamic agent runtime / Lifecycle reasoning (cs.CL, cs.AI)\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy it matters\u003c/strong\u003e: When agents can modify their own runtime, \u0026ldquo;how a plugin change propagates\u0026rdquo; becomes a new reasoning burden; this benchmark quantifies the unreliability zone with 1,200 questions — pouring cold water on \u0026ldquo;letting models freely modify code\u0026rdquo; while also pointing the way.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eLink\u003c/strong\u003e: \u003ca href=\"https://arxiv.org/abs/2609.01600\"\u003ehttps://arxiv.org/abs/2609.01600\u003c/a\u003e\u003c/p\u003e\n\u003ch3 id=\"6-skillglow-procedural-family-skill-consolidation-for-self-improving-agents-on-long-horizon-task-streams\"\u003e6. SkillGLoW: Procedural-Family Skill Consolidation for Self-Improving Agents on Long-Horizon Task Streams\u003c/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAbstract\u003c/strong\u003e: LLM agents increasingly self-improve by writing and reusing textual skills, kept either as one global document or as a flat pool of per-task entries, though most of the evidence comes from domains with structurally similar tasks. On long-horizon workloads where each task demands a different solution, the two forms fail in opposite ways: the document collapses into generic discipline, while the pool inflates and its entries stay bound to the instance that wrote them. We argue the missing unit of reuse is the solving procedure shared by a cluster of related tasks, and build SkillGLoW (Global-Local Weave) around it: the local skills a task writes from its own execution are aggregated into procedural families and compressed into de-instantiated global priors, while the instance detail they hold is regenerated per task rather than stored; a commit gate admits a prior only when real execution shows it does not degrade the deployed library. Across four benchmarks (mathematical reasoning, terminal automation, software repair, and embodied control) and three models, the priors gain 17.2 points (hard) over the no-skill baseline on average, with positive gains in all 12 continual-improvement runs, and 18.0 with local regeneration, while the library holds one prior per procedural family, 3.6x more compact than the per-task pool. Under the same protocol GLoW leads a published single-document optimizer on 15 of 21 cells. Unmodified, the library lifts success on unseen ALFWorld tasks from 73.9% to 83.9%, evidence that what transfers is procedure rather than task memory.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eDomain\u003c/strong\u003e: Self-improving agents / Skill consolidation (cs.AI)\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy it matters\u003c/strong\u003e: Proposes the \u0026ldquo;procedural family\u0026rdquo; as the minimal unit of skill reuse — less vacuous than a global document and 3.6× more compact than a per-task pool — and lifts unseen ALFWorld success from 73.9% to 83.9%; critical for memory design in long-term self-evolving agents.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eLink\u003c/strong\u003e: \u003ca href=\"https://arxiv.org/abs/2609.02217\"\u003ehttps://arxiv.org/abs/2609.02217\u003c/a\u003e\u003c/p\u003e\n\u003ch3 id=\"7-fuse-an-evaluating-framework-for-dangerous-capabilities-of-llms\"\u003e7. FUSE: An Evaluating Framework for Dangerous Capabilities of LLMs\u003c/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAbstract\u003c/strong\u003e: Fragmented safety evaluation undermines the governance of dangerous AI capabilities. We present a modular framework that evaluates each model through three orthogonal pipelines — Knowledge (K), Defense (D), and Harm (H) — under a unified protocol, aggregating results into a standardized dangerous-capability profile φ. Pluggable modules supply scenario seeds, knowledge banks, hazard queries, and judge rubrics, while the core evaluation engine remains unchanged across domains; the CB evaluation is complemented by a cyber pilot demonstrating protocol transfer. Instantiating the framework with a chemical-biological (CB) module, we evaluate 12 commercial LLMs from four families. Our first contribution is a horizontal comparison of dangerous capability across models and model families: the three dimensions expose sharply divergent profiles — models with comparable knowledge differ in refusal resilience, and strong defenders do not generate less harmful content when they do comply — while family-level patterns further separate Claude, DeepSeek, and GPT models. The second is a temporal analysis of capability evolution: tracking K, D, and H against model release dates reveals that dangerous capability has not monotonically declined; newer models deepen knowledge while only partially improving defense, showing that scaling and alignment progress do not uniformly translate into safety. Reliability is established via cross-judge consistency (bootstrap ρ \u0026gt; 0.79, 4 of 5 judges) and pipeline orthogonality (K–D–H inter-correlations ρ ∈ [0.32, 0.52]).\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eDomain\u003c/strong\u003e: AI safety evaluation / Dangerous-capability profiling (cs.AI)\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy it matters\u003c/strong\u003e: Three orthogonal K/D/H pipelines turn \u0026ldquo;dangerous capability\u0026rdquo; into a standardizable profile and empirically show \u0026ldquo;newer isn\u0026rsquo;t necessarily safer\u0026rdquo; — echoing this week\u0026rsquo;s OpenAI Astra safety debate and giving regulators a reusable yardstick.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eLink\u003c/strong\u003e: \u003ca href=\"https://arxiv.org/abs/2609.02168\"\u003ehttps://arxiv.org/abs/2609.02168\u003c/a\u003e\u003c/p\u003e\n\u003ch3 id=\"8-beyond-context-windows-persistent-discovery-context-for-data-centric-agents\"\u003e8.

Yet successful discovery outcomes are typically discarded rather than reused. We introduce persistent discovery context, a lightweight memory layer that stores prior intent-to-object mappings and reuses them to augment future retrieval. Across three structured data environments, persistent discovery context consistently improves retrieval quality over metadata-only search, remains effective with automatically generated memories, and exposes a reproducible interference failure mode. In lexically sparse domains, memory-only retrieval can even outperform metadata-based retrieval.
