AI voice agent prompts function like type-checked code, but aren't

By PulseAugur Editorial · [1 sources] ·

This article discusses the challenges of using dynamic variables in AI voice agents, particularly with the Retell platform. The author explains that these variables, when used in prompts, function like function signatures in traditional programming but lack type-checking, leading to potential errors. Common issues include missing arguments, which can cause the AI to read raw placeholders aloud, and name mismatches between the prompt and the provided data. The post suggests best practices such as providing default values for all variables and handling cases where information might be missing to ensure robust agent performance. AI

    A Prompt With {{Placeholders}} Is a Function Signature Nobody Type-Checks

    <p>If you have written a function, you already understand Retell's dynamic variables better than most agencies using them. You just have not been told that a prompt with <code>{{first_name}}</code> in it is a function signature, and that nothing type-checks the call site.</p> <p>…
