## Prerequisites

agent-browser snapshot -i
```

agent-browser press Enter         # Press key
```

### Extract data

```bash

```

## Common Workflows

### Login flow

```

## Options

- `--json` - JSON output for parsing
- `--headed` - Show browser window (for debugging)
- `--session-name <name>` - Persist session cookies
- `--profile <path>` - Use persistent browser profile

## Configuration

The browser tool is enabled by default with `allowed_domains = ["*"]` and
`backend = "agent_browser"`. To customize, edit `~/.zeroclaw/config.toml`:

```toml
[browser]
enabled = true              # default: true
allowed_domains = ["*"]     # default: ["*"] (all public hosts)
backend = "agent_browser"   # default: "agent_browser"
native_headless = true      # default: true
```

To restrict domains or disable the browser tool:

```toml
[browser]
enabled = false                              # disable entirely
# or restrict to specific domains:
allowed_domains = ["example.com", "docs.example.com"]
```

Run `agent-browser --help` for all available commands.
