LLM agent (agentic flow)
Beginner
An AI model that does more than answer: it runs tools, looks at the results and decides what to do next, step by step.
Novice
A setup in which a language model works in a loop: it plans a step, runs a tool (a simulator, a checker, a design tool), reads the output and decides what to do next.
Expert
Tool feedback grounds the model in real results, and invalid tool calls fail visibly. The risks are mistakes that compound over long loops, cost per task, and success criteria that only check that a script ran, leaving the design goal unchecked.
