### Scope & Focus

**OpenCode** is a general-purpose AI coding agent. It can edit files, refactor code, explain codebases, and run terminal commands. It's designed to be a comprehensive coding assistant.

**Caro** intentionally does one thing well: helping you remember and safely execute shell commands. It's a specialized sub-agent, not a full coding assistant. This focus allows for deeper expertise in shell workflows and stronger safety guarantees.

### Safety Philosophy

**OpenCode** generates commands without systematic pre-execution validation. While you can review commands before running them, there's no dedicated layer that catches dangerous patterns.

**Caro** validates every command against 52+ predefined safety patterns. Commands like `rm -rf /`, fork bombs, and system-breaking operations are blocked before they're ever shown to you. Safety isn't optional—it's built into the core.

### Complementary Use

These tools can work together! Use **OpenCode** for general coding tasks—editing files, explaining code, refactoring. When you need shell command help with safety guarantees, reach for **Caro**.

Caro is designed to be a focused companion, not a replacement for broader tools. Its lightweight, specialized nature makes it easy to add to any workflow without overlap.

### Local Operation

**OpenCode** supports local operation with various model backends, though some configurations may require internet for model downloads or API calls.

**Caro** is designed offline-first from the ground up. Once you have local models configured, it never needs internet. Perfect for air-gapped environments, flights, or restrictive networks.

## Which Should You Choose?

Or use both—they complement each other well!

### Choose Caro if...

- You need specialized shell command assistance
- Rule-based safety validation is important to you
- You want a lightweight, focused tool
- Air-gapped / offline-first is a requirement
- You're adding to (not replacing) your existing tools
