An agent is not a chatbot.
It reads data, does one job, and logs what it has done. It does not continue conversations across days, and it has no opinions about anything other than what it was built for.
The difference is not cosmetic. A chatbot is an interface with a language model behind it; it suggests, guesses, fills in. An agent is a work tool that reads the structure of your systems directly — your accounting software, your online store, whatever it works in — does one thing correctly, and stays out of everything else. We have built every agent that way — narrow, on purpose.
