# Sandbox Status Command

Inspect the native Claude Code sandbox state, active configuration, and security events.

## Usage

```
/sandbox-status
```

## What It Does

1. **Check sandbox availability**
   - Verify OS primitives installed (bubblewrap on Linux, Seatbelt on macOS)
   - Display platform support status

2. **Show active configuration**
   - Sandbox mode (Auto-allow vs Regular permissions)
   - Filesystem policies (allowed writes, denied reads)
   - Network policies (domain allowlist/denylist)
   - Excluded commands

3. **List recent sandbox violations**
   - Blocked filesystem access attempts
   - Blocked network connections
   - Escape hatch invocations (`dangerouslyDisableSandbox`)

## Implementation

```bash
#!/bin/bash

## Use Cases

- **Pre-deployment**: Verify sandbox config before running autonomous workflows
- **Debugging**: Investigate why certain commands are blocked
- **Security audit**: Review allowed domains and filesystem access
- **Onboarding**: Help new team members understand project sandbox policy
