Summary  
This chapter explains how to augment an AI model by orchestrating external tool calls—specifically invoking a web search function—so it can fetch up-to-date information and integrate those results into its reasoning.  

General domain of usage  
Marketing

In the previous chapter you talked to Claude. Now you'll watch it **reach outside itself** to fetch real information.


## What Claude Knows — and Doesn't

Claude was trained on a large collection of text up to a point in time. It knows a lot, but it has no access to:

- today's headlines;
- your email or spreadsheets;
- your company's internal documents.

None of that was in its training data.

## What is a Tool?

A **tool** is a function the AI can call when it doesn't know something. Here's the full chain:

1. You ask a question — "How do marketing managers use AI today?"
2. Claude decides to call the **web_search** tool;
3. The tool searches the web and returns results;
4. Claude reads those results and gives you an answer.

In a normal AI chat, this is hidden. In Codefinity, you'll see each step — tool call, tool response, final answer.

## Why this Matters for Your Job

**You stop expecting magic.** Claude doesn't know recent events by default — but you can ask it to search.

**You understand hallucinations.** When no tool is available, the model fills gaps with patterns. That's when it invents facts.

**You write better prompts.** There's a difference between:

><b>What are three examples?

and:

><b>Use web search to find three examples.

Small change, much better results.

## Task

The lab on the right has web search enabled. Tell Claude your role and ask it to research how people in that role use AI today:

><b>I'm a marketing manager. Use web search to find 3 real examples of how people in my role use AI today.

While it works, watch the right panel. You'll see the **tool call** appear before the answer — Claude's own search query, the raw results, and then the final response.

Done when you've seen the tool call and got a relevant answer. Hit **Next chapter**.
