# Null Terminal

> **"Shell in the Void."**

[![Python 3.12+](https://img.shields.io/badge/python-3.12+-blue.svg)](https://www.python.org/downloads/)
[![Built with Textual](https://img.shields.io/badge/Built%20with-Textual-blueviolet)](https://textual.textualize.io/)

> [!NOTE]
> Null Terminal is under active development and not yet officially released. Features and APIs may change.

Null is a next-generation TUI (Terminal User Interface) designed for the modern AI-integrated workflow. Built on [Textual](https://textual.textualize.io/), it blends the raw power of the command line with the intelligence of LLMs, all wrapped in a sleek, cyber-noir aesthetic.

## Why Null?

- **Two Modes, One Interface**: Seamlessly switch between CLI and AI mode with `Ctrl+Space`
- **Block-Based Output**: Every command and response is a distinct, interactive block
- **20+ AI Providers**: From local Ollama to cloud providers like OpenAI, Anthropic, and Google
- **Agent Mode**: Let the AI execute multi-step tasks autonomously
- **MCP Integration**: Extend AI capabilities with Model Context Protocol servers

docker run -it --rm ghcr.io/starhound/null-terminal:latest
```

**From Source:**
```bash
git clone https://github.com/starhound/null-terminal.git
cd null-terminal
uv sync
uv run main.py
```

See [Installation Guide](docs/user/installation.md) for Windows, advanced options, and troubleshooting.

### First Run

1. **Configure AI Provider**: Type `/settings` or press `F3`
2. **Select a Model**: Press `F2` or type `/model`
3. **Toggle AI Mode**: Press `Ctrl+Space` to switch between CLI and AI

### Basic Usage

```bash
# CLI Mode (default)
ls -la                    # Run shell commands
cd ~/projects             # Navigate directories

# AI Mode (Ctrl+Space to toggle)
Explain this error        # Ask questions
Refactor this function    # Get code help

# Slash Commands (always available)
/help                     # Show help
/model                    # Select AI model
/agent                    # Toggle agent mode
/todo                     # Task manager
/theme dracula            # Change theme
```

## AI Providers

### Local (Free)

| Provider | Setup |
|----------|-------|
| **Ollama** | `ollama pull llama3.2` then `/provider ollama` |

| **Llama.cpp** | Start server, then `/provider llama_cpp` |

### Cloud

| Provider | Models |
|----------|--------|
| **OpenAI** | GPT-4o, GPT-4 Turbo, o1 |
| **Anthropic** | Claude 3.5 Sonnet, Claude 3 Opus |
| **Google** | Gemini 2.0 Flash, Gemini 1.5 Pro |

## Agent Mode

Enable autonomous task execution:

```bash
/agent                    # Toggle agent mode

# Then ask:
"Create a Python script that fetches weather data and saves it to weather.json"
```

The agent will:
1. Plan the approach
2. Execute tools (read/write files, run commands)
3. Iterate until the task is complete

Safety features:
- Tool approval prompts for dangerous operations
- Maximum 10 iterations per task
- Cancel anytime with `Escape`

---

## MCP Integration

Add external tools via Model Context Protocol:

```bash
/mcp catalog              # Browse available servers
/mcp add                  # Add a server manually
/mcp tools                # List available tools
```

Popular MCP servers:
- **Brave Search** - Web search
- **Filesystem** - File operations
- **PostgreSQL** - Database queries
- **GitHub** - Repository management
