# Browser Automation with agent-browser

Comprehensive browser automation for testing, data extraction, and web interaction.

## Quick Start

```bash
agent-browser open <url>        # Navigate to page
agent-browser snapshot -i       # Get interactive elements with refs
agent-browser click @e1         # Click element by ref
agent-browser fill @e2 "text"   # Fill input by ref
agent-browser close             # Close browser
```

## Core Workflow

1. **Navigate**: `agent-browser open <url>`
2. **Snapshot**: `agent-browser snapshot -i` (returns elements with refs like `@e1`, `@e2`)
3. **Interact** using refs from the snapshot
4. **Re-snapshot** after navigation or significant DOM changes

## Installation

```bash
# Install globally
npm install -g agent-browser

# Or use via npx
npx agent-browser open https://example.com
```

## Commands Reference

agent-browser reload          # Reload page
agent-browser close           # Close browser
```

### Page Analysis (Snapshot)

```bash
agent-browser snapshot            # Full accessibility tree
agent-browser snapshot -i         # Interactive elements only (RECOMMENDED)
agent-browser snapshot -c         # Compact output
agent-browser snapshot -d 3       # Limit depth to 3
agent-browser snapshot -s "#main" # Scope to CSS selector
