Developer builds Qwen tool-calling agent with essential feedback loop

By PulseAugur Editorial · [1 sources] ·

A developer details how to build a functional tool-calling agent using the Qwen API, emphasizing the importance of a continuous loop for agent behavior. The process involves defining tools with clear descriptions to guide the model, and crucially, feeding the results of executed tools back into the conversation history. This loop allows the model to process tool outputs and decide on subsequent actions, differentiating a true agent from a single-step execution. AI

IMPACT Demonstrates a practical approach to building AI agents, highlighting the necessity of continuous feedback loops for effective multi-step task execution.

    I Built a Tool-Calling Agent on Qwen. Here's the Full Working Loop.

    <p>Tool Calling Is the Easy Part. The Loop Is Where It Gets Real.</p> <p>My first "agent" wasn't actually an agent. It was one API call that returned a tool call, which I executed, and then I just... stopped, because I hadn't written anything to feed the result back in. It looked…
