CC - Tools
Now that we've chatted with Claude a bit and identified the code for the Home page, let's take a quick detour to talk about one of the most powerful parts of any AI agent — tools.
Tools are what allow Claude to actually go out and do things beyond just chatting — browse the web, read files, run commands, edit code, and more. Claude Code comes with a rich set of built-in tools and can pick the right one automatically based on what you ask for.
You don't need to explicitly invoke tools. Just describe what you want and Claude will figure out which tool to use. Let's try it now.
We're going to keep working on the Home page. Since our app is built by Bitovi, let's add a "Created By" section. First, let's have Claude research the company:
✏️ Run this prompt
Do some research on Bitovi: - Basic info about the company - Logo - Brand colors
Claude will browse Bitovi's website and any other relevant sources, then come back with everything requested. When it tries to fetch a URL, it will ask for your approval first — you'll see a permission prompt in the terminal. This is by design: any time Claude wants to do something with side effects, it checks in with you.
Permissions
You can control this behavior via Claude Code's permission settings:
Default — Claude asks before fetching URLs, running commands, or editing files
Auto mode — Claude proceeds automatically for low-risk actions (set in your session with
/permissionsor configured insettings.json)
Once Claude finishes the research, that information stays in the conversation history for the rest of the session — Claude can reference it in every follow-up prompt.
Automatic Tool Selection
In this example we didn't specify any tool syntax — we just described what we wanted. Claude chose to use its web fetch capability on its own. This is how Claude Code works: you describe the goal, Claude picks the tools.
Feel free to explore more — ask Claude questions that require different capabilities (reading files, searching the codebase, looking something up) and watch it select the right tool automatically.
