## Overview

Wardstone provides platform-specific sandboxing for AI agent tool execution:

- **macOS**: Seatbelt (sandbox-exec) with auto-generated .sbpl policies
- **Linux**: Landlock LSM for filesystem isolation
- **Windows**: Windows Sandbox (planned)

## Features

- 🔒 Filesystem isolation (read/write/execute permissions)
- 🌐 Network access control
- ⏱️ Execution timeouts
- 🎯 Path-based permissions
- 🔧 Easy policy builder API

## Installation

```toml
[dependencies]
wardstone = "0.1"
```

## Usage

```rust
use wardstone::{SandboxPolicy, create_sandbox, NetworkPolicy};
use std::process::Command;

// Create a restrictive policy
let policy = SandboxPolicy::new()
    .allow_read("/usr")
    .allow_read("/lib")
    .allow_write("./output")
    .with_network(NetworkPolicy::None)
    .with_timeout(std::time::Duration::from_secs(60));

// Create platform-specific sandbox
let sandbox = create_sandbox(policy)?;

// Wrap a command with sandbox restrictions
let cmd = Command::new("./my-script.sh");
let sandboxed_cmd = sandbox.wrap_command(cmd)?;
```

## Policy Builder

```rust
use wardstone::{SandboxPolicy, NetworkPolicy};

let policy = SandboxPolicy::default_for_tools("/home/user/project".into())
    .allow_read("/tmp")
    .allow_localhost()  // Allow localhost network only
    .allow_spawn(true); // Allow spawning subprocesses
```

## Platform Support

| Platform | Implementation | Status |
|----------|----------------|--------|
| macOS    | Seatbelt       | ✅ Complete |
| Linux    | Landlock       | ✅ Complete |
| Windows  | Windows Sandbox| 🚧 Planned |
