With the rapid development of AI Agent technology, more and more applications are adopting agent architectures to perform complex tasks. Agents can autonomously complete work that traditional programs find difficult through multi-step reasoning, tool calls, and state management. However, this autonomy also brings observability challenges—when an agent encounters execution issues, developers often struggle to track and understand its decision-making process.
Traditional logging and debugging tools fall short when dealing with the dynamic execution flow of agents. The execution path of an agent may change based on different inputs, with complex intermediate states and long tool call chains, all of which increase debugging difficulty. Visualization becomes a key solution to this problem; by graphically displaying the agent's execution flow, developers can intuitively understand its behavioral logic.
