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)

  Excluded commands: docker, kubectl, podman

Recent sandbox violations:
  ℹ️  Log inspection not yet implemented
  Tip: Check Claude Code session logs for sandbox violation notifications

Open-Source Runtime:
