## Overview

The CLI is the foundational interface for CAI, offering:

- **⚡ Lightweight Execution**: Minimal resource overhead for maximum performance
- **🤖 Direct Agent Interaction**: Immediate access to all CAI agents
- **📝 Command System**: 30+ built-in commands for complete control
- **🔄 Automation Ready**: Perfect for scripting and CI/CD pipelines
- **🧩 Queue System**: Batch processing with command chaining
- **⚙️ Parallel Execution**: Run multiple agents simultaneously
- **💾 Session Management**: Save and restore conversations
- **🔧 Shell Integration**: Direct shell command execution

## When to Use the CLI vs TUI

| Feature | CLI | TUI |
|---------|-----|-----|
| **Scripting/Automation** | ✅ Full support | ❌ Interactive only |
| **CI/CD Integration** | ✅ Perfect fit | ❌ Not suitable |
| **Resource Usage** | ✅ Minimal | ⚠️ Higher (UI overhead) |
| **Batch Processing** | ✅ Queue system | ⚠️ Limited |
| **Visual Feedback** | ⚠️ Text-based | ✅ Rich UI |
| **Multi-agent Workflows** | ✅ Parallel mode | ✅ Visual split-screen |
| **Remote/Headless** | ✅ SSH friendly | ⚠️ Requires terminal UI |
| **Learning Curve** | ⚠️ Steeper | ✅ Intuitive |

**Use CLI for**: Automation, scripting, CI/CD, headless servers, SSH sessions, batch processing

**Use TUI for**: Interactive testing, visual multi-agent workflows, exploratory analysis, real-time monitoring

## Quick Start

Launch the CLI:

```bash
cai
```

With an initial prompt:

```bash
cai --prompt "scan 192.168.1.1 for open ports"
```

With YAML configuration:

```bash
cai --yaml agents.yaml
```

Basic workflow:

1. Launch CAI: `cai`
2. Configure API key in `.env` or environment
3. Select a model: `/model alias1`
4. Choose an agent: `/agent redteam_agent`
5. Type your prompt and press **Enter**

See the [Getting Started Guide](getting_started.md) for detailed instructions.

## Key Features

### 🎯 Command System

Over 30 built-in commands organized by category:

- **Agent Management**: `/agent`, `/parallel`
- **Memory & History**: `/memory`, `/history`, `/compact`, `/flush`, `/load`, `/merge`, `/save`
- **Environment**: `/env` (catalog `list` / `get` / `set` / `default`), `/help var` (per-variable help), `/workspace`, `/virtualization`
- **Tools & Integration**: `/mcp`, `/shell`
- **Utilities**: `/model`, `/graph`, `/cost`, `/help`

All commands support aliases for faster typing (e.g., `/a` for `/agent`, `/h` for `/help`).

### ⚡ Parallel Execution

Run multiple agents simultaneously:

```bash
# Configure parallel agents
/parallel add redteam_agent
/parallel add bug_bounter_agent
/parallel add blueteam_agent

# Execute on all agents
/parallel run "analyze target.com"
```

Or use YAML configuration:

```bash
cai --yaml agents.yaml --prompt "test application security"
```

### 💻 Shell Integration

Execute shell commands directly:

```bash
# Using /shell command
/shell nmap -sV 192.168.1.1

# Using $ shortcut
$ whoami

# Using /$ alias
/$ ls -la
```

### 💾 Session Management

Save and restore conversations:

```bash
# Save current session
/save pentest_session.json

# Save as Markdown report
/save findings_report.md

# Load previous session
/load pentest_session.json
```

### 🧠 Memory Management

Advanced memory features for long-term context:

```bash
# Enable episodic memory
CAI_MEMORY=episodic cai

# Save memory snapshot
/memory save "web app vulnerabilities found"

# List saved memories
/memory list

# Apply memory to current session
/memory apply mem_12345
```

## System Requirements

- **Python**: 3.9 or higher
- **Terminal**: Any modern terminal (bash, zsh, fish)
- **API Key**: Valid `ALIAS_API_KEY` (get one from [Alias Robotics](https://aliasrobotics.com))
- **Operating System**: Linux, macOS, Windows (WSL recommended)

### Supported Terminals

- ✅ bash (Linux/macOS/WSL)
- ✅ zsh (macOS/Linux)
- ✅ fish (Linux/macOS)
- ✅ PowerShell (Windows)
- ✅ SSH sessions
- ✅ tmux/screen
- ✅ CI/CD environments
