What 'Tools' an AI Agent Can Use

AI agents have tools — like web search, calculator, and code-runner — they pick from.

The big idea

AI agents have a toolbox: web search, calculator, calendar, email, code-runner. AI picks the right tool for each job.

Some examples

For 'what's the weather?' → AI uses the weather tool.
For 'what's 7382 × 19?' → AI uses the calculator tool.
For 'remind me at 5pm' → AI uses the calendar tool.
For 'find a recipe' → AI uses the web search tool.

Try it!

Make a list of 5 questions. Next to each, guess which 'tool' AI would use. Then ask AI and see if you're right!

Practice this safely

Try this with a low-stakes example and a trusted adult nearby. The goal is to notice how AI talks about tools, not to let it make the decision for you.

Ask AI to explain tools in plain language, then underline anything that sounds uncertain or too broad.
Give it one detail from "What 'Tools' an AI Agent Can Use" and ask for two possible next steps plus one reason each step might be wrong.
Check abilities against a trusted source, teacher, adult, expert, or original document before you use it.

3. For 'what's the weather?' → AI uses the weather tool.
4. Trust the first answer because it sounds confident
What should a careful learner remember about "AI has a toolbox"?

2. Use short, concrete wording and ask a trusted adult when the stakes matter.
3. Hide uncertainty so the final answer looks cleaner
4. Use private or sensitive details before checking permission
How should AI output about tools be treated?
1. As proof that no other source is needed
2. As a replacement for context, consent, or expert review
