# 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`)

## 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
