AI agents: Testing tool-calling decisions for bugs

By PulseAugur Editorial · [1 sources] ·

Testing AI agents for tool-calling errors can be done by focusing on individual decisions rather than entire conversations. This approach involves setting up test cases that include the available tools with their JSON schemas, the conversation history, the expected correct response (including specific tool calls or no call), and a list of tools that should never be invoked. By isolating each decision, failures pinpoint exact issues, such as incorrect data types, missing required arguments, or the agent attempting to use forbidden tools based on instructions embedded within tool results or user prompts. This method allows for cheap and safe execution within continuous integration pipelines. AI

    How to test tool calling in your AI agent, one decision at a time

    <p>Many agent bugs are not about bad prose. They are about bad tool calls. The agent picks the wrong tool. It sends a string where the schema wants an integer. It guesses a value the user never gave. It follows an instruction it found inside a web page.</p> <p>These bugs are easy…
