tool calling

Tool calling powers every agent. The signal is knowing the model executes nothing: it emits a structured request your code runs, then you feed the result back. Here is the loop and the details that decide reliability.

A live-coding round that separates people who have shipped agents from people who have read about them. The signal is a real plan-act-observe loop, tools that hit an actual SQL database, guardrails that stop the obvious failures, and a concrete evaluation plan, not a single prompt that pretends to be an agent.
