macOS sandbox-exec guards AI agents so rm -rf can't wreck your whole machine.

Strengths
  • Native sandbox-exec means zero VM overhead, no containers, no image to boot
  • Honest threat model: guards against accidents, not malicious agents trying to escape
  • Single auditable shell script with --print flag showing exact permissions granted
Weaknesses
  • Apple Silicon macOS only - no Linux, Windows, or Intel Mac support
  • sandbox-exec shares kernel with user account, not true containment boundary
Target Audience

macOS developers using Claude Code or Codex who want safety guardrails
