# Browser Automation with agent-browser

Use `agent-browser` CLI tool for all browser automation tasks. This is the preferred method for web interactions.

## Important: Command Sequence

**Always follow this sequence:**

1. `agent-browser launch` - Start the browser first
2. `agent-browser open <url>` - Navigate to a URL
3. Perform operations (snapshot, click, type, etc.)
4. `agent-browser close` - Close when done

## Quick Reference

First, run `agent-browser` without arguments to see full help:

```bash
agent-browser
```

### Essential Commands

| Command | Description |
|---------|-------------|
| `agent-browser launch` | Start browser (required before open) |
| `agent-browser open <url>` | Navigate to URL |
| `agent-browser snapshot` | Get page content as text |
| `agent-browser snapshot -i` | Get page content with element IDs for interaction |
| `agent-browser screenshot` | Take screenshot |
| `agent-browser click <selector>` | Click an element |
| `agent-browser type <selector> <text>` | Type text into input |
| `agent-browser close` | Close browser |

### Common Workflows

**View webpage content:**
```bash
agent-browser launch
agent-browser open https://example.com
agent-browser snapshot
agent-browser close
```

**Take screenshot:**
```bash
agent-browser launch
agent-browser open https://example.com
agent-browser screenshot
agent-browser close
```

**Fill form and submit:**
```bash
agent-browser launch
agent-browser open https://example.com/login
agent-browser snapshot -i  # Get element IDs
agent-browser type "#username" "myuser"
agent-browser type "#password" "mypass"
agent-browser click "#submit"
agent-browser close
```

**Extract data from page:**
```bash
agent-browser launch
agent-browser open https://example.com/data
agent-browser snapshot  # Returns structured text content
agent-browser close
```

## Tips

1. **Always launch first**: `agent-browser open` will fail if browser isn't launched
2. **Use snapshot -i for interactions**: The `-i` flag shows element IDs needed for click/type
3. **Check help for more options**: Run `agent-browser <command> --help` for detailed options
4. **Close when done**: Always close the browser to free resources

## When NOT to Use

- For simple HTTP requests without JavaScript rendering, use `curl` or `WebFetch`
- For API calls, use appropriate HTTP tools
- agent-browser is for full browser automation with JavaScript support

## Troubleshooting

If `agent-browser` command not found:
```bash
npm install -g agent-browser
agent-browser install
```

If browser fails to launch on Linux:
```bash
agent-browser install --with-deps
```
