```bash
agent-browser network route <url>              # Intercept requests
agent-browser network route <url> --abort      # Block requests
agent-browser network route <url> --body '{}'  # Mock response
agent-browser network unroute [url]            # Remove routes
agent-browser network requests                 # View tracked requests
agent-browser network requests --filter api    # Filter requests
```

## Tabs and Windows

```bash
agent-browser tab                 # List tabs
agent-browser tab new [url]       # New tab
agent-browser tab 2               # Switch to tab by index
agent-browser tab close           # Close current tab
agent-browser tab close 2         # Close tab by index
agent-browser window new          # New window
```

## Frames

```bash
agent-browser frame "#iframe"     # Switch to iframe by CSS selector
agent-browser frame @e3           # Switch to iframe by element ref
agent-browser frame main          # Back to main frame
```

### Iframe support

Iframes are detected automatically during snapshots. When the main-frame snapshot runs, `Iframe` nodes are resolved and their content is inlined beneath the iframe element in the output (one level of nesting; iframes within iframes are not expanded).

```bash
agent-browser snapshot -i
# @e3 [Iframe] "payment-frame"
#   @e4 [input] "Card number"
#   @e5 [button] "Pay"

# Interact directly — refs inside iframes already work
agent-browser fill @e4 "4111111111111111"
agent-browser click @e5

# Or switch frame context for scoped snapshots
agent-browser frame @e3               # Switch using element ref
agent-browser snapshot -i             # Snapshot scoped to that iframe
agent-browser frame main              # Return to main frame
```

The `frame` command accepts:
- **Element refs** — `frame @e3` resolves the ref to an iframe element
- **CSS selectors** — `frame "#payment-iframe"` finds the iframe by selector
- **Frame name/URL** — matches against the browser's frame tree

## Dialogs

By default, `alert` and `beforeunload` dialogs are automatically accepted so they never block the agent. `confirm` and `prompt` dialogs still require explicit handling. Use `--no-auto-dialog` to disable this behavior.

```bash
agent-browser dialog accept [text]  # Accept dialog
agent-browser dialog dismiss        # Dismiss dialog
agent-browser dialog status         # Check if a dialog is currently open
```

## JavaScript

```bash
agent-browser eval "document.title"          # Simple expressions only
agent-browser eval -b "<base64>"             # Any JavaScript (base64 encoded)
agent-browser eval --stdin                   # Read script from stdin
```

Use `-b`/`--base64` or `--stdin` for reliable execution. Shell escaping with nested quotes and special characters is error-prone.

```bash
# Base64 encode your script, then:
agent-browser eval -b "ZG9jdW1lbnQucXVlcnlTZWxlY3RvcignW3NyYyo9Il9uZXh0Il0nKQ=="

# Or use stdin with heredoc for multiline scripts:
cat <<'EOF' | agent-browser eval --stdin
const links = document.querySelectorAll('a');
Array.from(links).map(a => a.href);
EOF
```

## State Management

```bash
agent-browser state save auth.json    # Save cookies, storage, auth state
agent-browser state load auth.json    # Restore saved state
```
