This paper proposes a dynamic multi-agent system (MAS) within the AWorld framework, consisting of executive and supervisory agents, to address the reliability issues that arise when intelligent agents based on large-scale language models (LLMs) utilize external tools to solve complex real-world problems. Specifically, we use a methodology inspired by system identification in control theory to generate performance profiles of executive agents. Based on these profiles, the supervisory agent performs goal-oriented interventions tailored to the agent's unique weaknesses, thereby enhancing the system's robustness. Experimental results using the GAIA dataset demonstrate that the proposed profile-aware MAS significantly outperforms single-agent systems and general supervisory systems in terms of efficiency and stability, achieving the top ranking among open-source projects on the GAIA leaderboard. This demonstrates that building trustworthy intelligent systems requires not only inter-agent collaboration but also an empirical understanding of each agent's unique capabilities and limitations.
