# How to map how a website's front end behaves with rea

Let your agent inspect a site's page structure, scripts and network calls and explain what the client does.

**Who it is for:** Frontend developer curious how a web app wires its UI to its scripts and requests

**The problem:** Minified scripts and network traffic make it hard to see how a web app actually works.

**The outcome:** A summary of the page structure, scripts and observed network requests for the site.

## Steps

1. Run npx rea-agents setup and restart your agent.
2. Make sure a Chrome-family browser is installed.
3. Ask your agent to observe the target website with REA and list scripts and network calls.
4. Ask it to explain the part of the behavior you care about.

## Prompt to paste into your agent

```text
Use REA to observe <website url> in a browser and summarize its page structure, scripts and network requests. Explain how <feature> works and verify claims against the observed requests.
```

## Caveat

Observation covers the client side only. Server logic can only be inferred from responses, and you should respect the site's terms of use.
