Tools an AI Agent Can Use: Eyes, Hands, and a Calculator
An AI agent gets stuff done by using tools. A web browser. A calculator. A calendar. Just like you use tools to do tasks.

The big idea
An AI agent on its own is just a brain — it cannot DO anything. To take action, it needs tools. Tools let an agent see what is on a website, look up information, do math, or send a message.
Some examples
- A browser tool lets the agent visit a website and read what is there.
- A calculator tool lets it do math correctly (because AI is bad at math without one).
- A calendar tool lets it check when you are busy.
- A search tool lets it look stuff up on Google or other search engines.
Try it!
Imagine you got to design an agent for a kid your age. What 3 tools would you give it? Why those? What tools would you NOT give it?
