Description
CapLock is a cross-platform CLI that protects npm and pnpm projects from malicious lifecycle scripts. It intercepts scripts like postinstall and runs them inside a restricted sandbox with filesystem, environment, network, and child-process isolation

Could you build this?
No Creating a cross-platform process and filesystem sandbox (especially across Linux, macOS, and Windows) requires deep low-level systems programming and OS security expertise (e.g., eBPF/Landlock/cgroups on Linux, App Sandbox/Endpoint Security on macOS).
What it would actually take: A production tool needs a systems language like Rust or C/C++ interfacing with platform-specific kernel primitives: Landlock, seccomp, or namespaces on Linux; seatbelt/sandbox profiles or Endpoint Security on macOS; and AppContainers or restricted tokens on Windows. The core challenge is preventing sandbox escapes and handling cross-platform file, environment, and network hooking without breaking valid npm package builds. This requires specialized systems security engineering rather than standard AI prompt-generation.
