# Orbit

Orbit is a standalone code agent built in Zig.

## Vision

Orbit is a true autonomous coding assistant, not a frontend for another service. It provides:
- Direct file system operations
- Code execution and testing
- Interactive CLI and headless execution modes
- Fast, safe, and reliable operation

## Status

Currently in early development. The legacy opencode-zig prototype has been removed. The active codebase is organized around the `ai`, `agent`, and `cli` layers.

## Quick Start

Build and run:
```bash
zig build run
```

Run tests:
```bash
zig build test
```

Interactive slash commands (TTY mode):
- `/new` create a new session
- `/resume [session-id]` list or switch sessions
- `/model [provider/id]` show or switch model
- `/quit` exit (`/exit` alias kept)

Format code:
```bash
zig fmt src/*
```

## Project Structure

- `src/` - Source code
  - `main.zig` - Process entry point
  - `cli/` - CLI entry, config, sessions, tools, headless mode
  - `agent/` - Agent loop and tool e
