What Tools Agents Can Use
Modern agents can use tools — like a browser, an email client, a calculator, a calendar. They pick the right tool for the job.
An agent that can only chat is limited. An agent that can use tools is powerful — and dangerous if not supervised.
Three powerful tools agents have
- Browser (search and click anything)
- Email (send messages on your behalf)
- Payment APIs (actually buy things)
Key terms in this lesson
The big idea: Agents are only as powerful as the tools they can use.
Practice this safely
Try this with a school, hobby, or family example where the stakes are low. Use the AI output as a draft you can question, not as the final answer.
- 1Ask AI to explain tool use in plain language, then underline anything that sounds uncertain or too broad.
- 2Give it one detail from "What Tools Agents Can Use" and ask for two possible next steps plus one reason each step might be wrong.
- 3Check API against a trusted source, teacher, adult, expert, or original document before you use it.

Tool Use at the API Level: The Primitive
Underneath every agent framework is the same primitive — the model returns a structured tool call, you execute it, you feed the result back. Master this loop and every framework looks familiar.
