# Announcing Caro: Your Terminal's AI Companion

We're excited to announce that **cmdai** has been renamed to **caro**! 🎉

## A New Name, The Same Mission

Thanks to the incredible generosity of [@aeplay](https://github.com/aeplay), who graciously transferred the `caro` crate name to our project, we now have a name that better reflects our vision: a friendly, approachable AI companion for your terminal.

## What is Caro?

**caro** is a single-binary Rust CLI tool that converts natural language descriptions into safe POSIX shell commands using local LLMs. Built with safety-first design and optimized for Apple Silicon via the MLX framework, caro makes complex command-line operations accessible to everyone.

```
$ caro "find all PDF files larger than 10MB in Downloads"

Generated command:
  find ~/Downloads -name "*.pdf" -size +10M -ls

Execute this command? (y/N)
```

## Why "Caro"?

The name **caro** offers several advantages:

- **Brevity**: Shorter and easier to type (4 characters)
- **Memorability**: More distinctive and memorable as a brand
- **Pronounceability**: Natural pronunciation in multiple languages
- **Brandability**: Better suited for a product name

In Latin, *caro* means "dear" or "beloved"—fitting for a tool designed to make your terminal experience more friendly and approachable. And for those who know [Kyaro's story](https://caro.sh/blog/why-caro), the connection runs even deeper.

## Key Features

- 🚀 **Fast startup** - Single binary with quick initialization
- 🧠 **Local LLM inference** - Embedded models optimized for Apple Silicon (MLX) and CPU
- 🤖 **Intelligent refinement** - 2-iteration agentic loop for platform-specific commands
- 🌍 **Platform-aware** - Automatically detects OS, architecture, shell, and available commands
- 🛡️ **Safety-first** - Comprehensive validation with 52+ dangerous command patterns
- 📦 **Self-contained** - Single binary distribution
- 🎯 **Multiple backends** - Extensible system supporting MLX, CPU, vLLM, and Ollama

## Getting Started

### Quick Installation

```
# One-line setup (recommended)
bash <(curl --proto '=https' --tlsv1.2 -sSfL https://setup.caro.sh)

# Or via cargo
cargo install caro
```

### First Command

```
$ caro "show me the top 5 processes by CPU usage"
```

caro will generate the appropriate command for your platform, validate it for safety, and ask for confirmation before execution.

## What's New in v0.1.0

- ✅ Core CLI with comprehensive argument parsing
- ✅ Embedded model backend with MLX (Apple Silicon) and CPU variants
- ✅ Agentic context loop with iterative refinement
- ✅ Platform-aware command generation
- ✅ Safety validation with 52+ dangerous command patterns
- ✅ Remote backend support (Ollama, vLLM)
- ✅ Interactive execution with shell detection
- ✅ Multiple output formats (JSON, YAML, Plain)

## Migration from cmdai

If you previously installed `cmdai`, migration is simple:

```
# Uninstall old version
cargo uninstall cmdai

# Install new version
cargo install caro

# Migrate config (if you have custom configuration)
mv ~/.config/cmdai ~/.config/caro
```
