# Browser Automation with agent-browser

## 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

## Commands

### Navigation
```bash
agent-browser open <url>      # Navigate to URL (aliases: goto, navigate)
agent-browser back            # Go back
agent-browser forward         # Go forward
agent-browser reload          # Reload page
agent-browser close           # Close browser (aliases: quit, exit)
```

### Snapshot (page analysis)
```bash
agent-browser snapshot            # Full accessibility tree
agent-browser snapshot -i         # Interactive elements only (recommended)
agent-browser snapshot -i -C      # Include cursor-interactive elements (divs with onclick, etc.)
agent-browser snapshot -c         # Compact (remove empty structural elements)
agent-browser snapshot -d 3       # Limit depth to 3
agent-browser snapshot -s "#main" # Scope to CSS selector
agent-browser snapshot -i -c -d 5 # Combine options
```

The `-C` flag is useful for modern web apps that use custom clickable elements (divs, spans) instead of standard buttons/links.

### Interactions (use @refs from snapshot)
```bash
agent-browser click @e1           # Click (--new-tab to open in new tab)
agent-browser dblclick @e1        # Double-click
agent-browser focus @e1           # Focus element
agent-browser fill @e2 "text"     # Clear and type
agent-browser type @e2 "text"     # Type without clearing
agent-browser keyboard type "text"     # Type with real keystrokes (no selector, current focus)
agent-browser keyboard inserttext "text"  # Insert text without key events (no selector)
agent-browser press Enter         # Press key
agent-browser press Control+a     # Key combination
agent-browser keydown Shift       # Hold key down
agent-browser keyup Shift         # Release key
agent-browser hover @e1           # Hover
agent-browser check @e1           # Check checkbox
agent-browser uncheck @e1         # Uncheck checkbox
agent-browser select @e1 "value"  # Select dropdown
agent-browser scroll down 500     # Scroll page (--selector <sel> for container)
agent-browser scrollintoview @e1  # Scroll element into view (alias: scrollinto)
agent-browser drag @e1 @e2        # Drag and drop
agent-browser upload @e1 file.pdf # Upload files
```

### Get information
```bash
agent-browser get text @e1        # Get element text
agent-browser get html @e1        # Get innerHTML
agent-browser get value @e1       # Get input value
agent-browser get attr @e1 href   # Get attribute
agent-browser get title           # Get page title
agent-browser get url             # Get current URL
agent-browser get count ".item"   # Count matching elements
agent-browser get box @e1         # Get bounding box
agent-browser get styles @e1      # Get computed styles
```

### Check state
```bash
agent-browser is visible @e1      # Check if visible
agent-browser is enabled @e1      # Check if enabled
agent-browser is checked @e1      # Check if checked
```

### Screenshots & PDF
```bash
agent-browser screenshot          # Screenshot (saves to temp dir if no path)
agent-browser screenshot path.png # Save to file
agent-browser screenshot --full   # Full page
agent-browser screenshot --annotate   # Annotated screenshot with numbered element labels
agent-browser pdf output.pdf      # Save as PDF
```

Annotated screenshots overlay numbered labels `[N]` on interactive elements. Each label corresponds to ref `@eN`, so refs work for both visual and text workflows:
```bash
agent-browser screenshot --annotate ./page.png
# Output: [1] @e1 button "Submit", [2] @e2 link "Home", [3] @e3 textbox "Email"
agent-browser click @e2     # Click the "Home" link labeled [2]
```

### Video recording
```bash
agent-browser record start ./demo.webm    # Start recording (uses current URL + state)
agent-browser click @e1                   # Perform actions
agent-browser record stop                 # Stop and save video
agent-browser record restart ./take2.webm # Stop current + start new recording
```
Recording creates a fresh context but preserves cookies/storage from your session.

### Wait
```bash
agent-browser wait @e1                     # Wait for element
agent-browser wait 2000                    # Wait milliseconds
agent-browser wait --text "Success"        # Wait for text
agent-browser wait --url "**/dashboard"    # Wait for URL pattern
agent-browser wait --load networkidle      # Wait for network idle
agent-browser wait --fn "window.ready"     # Wait for JS condition
```

Load states: `load`, `domcontentloaded`, `networkidle`

### Mouse control
```bash
agent-browser mouse move 100 200      # Move mouse
agent-browser mouse down left         # Press button (left/right/middle)
agent-browser mouse up left           # Release button
agent-browser mouse wheel 100         # Scroll wheel
```

### Semantic locators (alternative to refs)
```bash
agent-browser find role button click --name "Submit"
agent-browser find text "Sign In" click
agent-browser find label "Email" fill "user@test.com"
agent-browser find placeholder "Search..." fill "query"
agent-browser find alt "Logo" click
agent-browser find title "Close" click
agent-browser find testid "submit-btn" click
agent-browser find first ".item" click
agent-browser find last ".item" click
agent-browser find nth 2 "a" text
```

Actions: `click`, `fill`, `type`, `hover`, `focus`, `check`, `uncheck`, `text`
Options: `--name <name>` (filter role by accessible name), `--exact` (require exact text match)

### Browser settings
```bash
agent-browser set viewport 1920 108
