Engineers Misunderstand LLM Tool Calling, Leading to Agent Failures

Engineers building LLM agents often make critical errors by treating tool calling as a standard API interaction. This approach fails because LLM callers are non-deterministic, can generate incorrect arguments, and struggle with error handling. Key mistakes include writing tool schemas for human readability rather than model comprehension, neglecting input validation before tool execution, and assuming the model will always choose the correct tool without ambiguity.

    Tool Calling Is Not an API Call: What Engineers Keep Getting Wrong

    <h4><em>Every team that builds an LLM agent eventually hits the same wall. The model calls a tool. Something breaks. Nobody knows why.</em></h4><figure><img alt="" src="https://cdn-images-1.medium.com/max/1024/1*0ijTuZp91MdqnmZfuphSow.png" /><figcaption>Illustration generated usi…
