\## Executive Summary

The research introduces DynaWeave, an innovative framework designed to enhance the capabilities of large language model (LLM) agents by enabling them to operate more effectively in dynamic environments. Traditional training environments for these agents tend to be static, which can limit their performance when faced with unexpected changes or external events. DynaWeave addresses this limitation by transforming static tasks into dynamic scenarios that better reflect real-world complexities.

The framework generates relevant external events that can impact task requirements, environmental states, and available information. It employs directed acyclic graphs (DAGs) to map out the relationships and dependencies among these events. This structured approach allows the framework to activate events during agent interactions, offering a more realistic training process.

A key feature of DynaWeave is its dynamic verification mechanism, which intelligently revises only the evaluation checks that are affected by the actual events that occur, while keeping all other checks intact. This efficiency is crucial for maintaining the integrity of the training process without overwhelming the system with unnecessary modifications.

The research demonstrates the effectiveness of DynaWeave through a series of experiments, collecting 2,095 verified interaction trajectories across 36 different environments. These trajectories were then used to fine-tune models, specifically the Qwen3.5, through supervised learning. The results were compelling: DynaWeave showed significant performance improvements in various evaluations, including a 67.34 percentage point increase in task completion rates on the CostBench benchmark. Notably, DynaWeave surpassed the performance of Gemini-3.1-Pro-Preview in ToolMaze, indicating its potential as a superior training method for agents operating in variable conditions.

The implications of this research are substantial for industries that rely on automation and AI agents. By utilizing a framework like DynaWeave, companies could enhance the adaptability and efficiency of their AI systems in real-world applications. This could lead to improved operational performance and better outcomes in environments where conditions can change rapidly and unpredictably.

The results stem from benchmark tests rather than real-world deployments, which suggests that while the findings are promising, further evaluation in actual operational settings would be necessary to fully understand the framework's impact. The research contributes to the growing body of knowledge around AI training methodologies, emphasizing the importance of dynamic scenario synthesis in preparing agents for the complexities of real-life tasks. The code used in this research is publicly available for those interested in exploring or building upon this work.

\## Academic Abstract

Large language model (LLM) agents increasingly use tools to complete tasks in stateful environments. However, many training environments remain largely static apart from changes caused by the agent's own actions, whereas external events introduced by other users, services, or sudden contingencies in real environments can invalidate ongoing plans. To address this gap, we introduce DynaWeave, an automated synthesis framework that transforms existing static tasks into verifiable dynamic scenarios. The framework generates exogenous events relevant to each task, covering changes in task requirements, environment state, and external information. It uses directed acyclic graphs (DAGs) to represent dependencies between events and an execution engine to activate them during agent interaction. A dynamic verifier revises only the evaluation checks affected by events that actually occur and retains all other checks. Using DynaWeave, we collect 2,095 verified interaction trajectories across 36 environments and use them for supervised fine-tuning of Qwen3.5 models. Experiments on Gaia2, CostBench, and ToolMaze show that DynaWeave achieves consistent improvements in overall performance across all three evaluated model sizes, increasing the task completion rate on CostBench by 67.34 percentage points and even exceeding the performance of Gemini-3.1-Pro-Preview on ToolMaze. These results support dynamic scenario synthesis as a practical approach to training agents to adapt to changing environments. Our code is available at https://github.com/Miaow-Lab/DynaWeave.
