315 行代码构建编程助手，Go大佬揭开智能体的「神秘面纱」

Core Viewpoint - Thorsten Ball has successfully built a programming agent using 315 lines of code, emphasizing that it runs well and lacks a competitive moat, making it easily replicable [1]. Group 1: Programming Agent Development - The programming agent, while not as advanced as Claude or Gemini, serves as a valuable learning example for beginners, reflecting Ball's philosophy of demystifying technology through practical and open-source projects [3]. - The construction of a small agent requires less than 400 lines of code, primarily consisting of boilerplate code, and involves a large language model, a loop, and sufficient tokens [4][10]. - The core functionality of the agent allows for a conversational interface with Claude, where it maintains context across multiple exchanges [13]. Group 2: Tool Integration - A significant aspect of the agent's functionality is its ability to use tools, defined as prompts that instruct the model on how to respond when it wants to utilize a specific tool [15]. - The process of defining tools involves specifying a name, description, input schema, and an execution function, which collectively enable the model to understand and utilize the tools effectively [22][24]. - The agent can autonomously determine when to use a tool based on the context of the conversation, demonstrating a level of independence in problem-solving [40]. Group 3: Practical Implementation - The agent's implementation includes a method to check if Claude requests a tool, executing it if necessary, and returning the results back to Claude [37][38]. - The example provided illustrates how the agent can read a file and respond to queries about its contents, showcasing its practical application in real-world scenarios [39][40]. - Additional tools such as list_files and edit_file can be integrated into the agent, further enhancing its capabilities [41].
