Why should I audit my sandbox before production?

Sandboxes often have permissive defaults; an audit ensures you aren't accidentally exposing ports or leaking secrets in a production environment.

Does it check for third-party dependency vulnerabilities?

Yes, it includes checks for Python and Node.js dependencies using tools like safety and npm audit as part of the comprehensive scan.

Can it audit my host machine's security?

No, this skill is strictly focused on the isolated Docker sandbox environment and the project-specific configurations defined in your repository.

Does this skill work with any Docker container?

While it uses standard Docker patterns, it is specifically optimized for Claude Code Docker sandboxes and DevContainer specifications.

Can it automatically fix the security issues it finds?

It provides the specific commands and configuration changes needed to fix issues, but requires user approval before implementation to ensure system stability.

Security & Testing

Performs comprehensive security audits and hardening for Claude Code Docker sandbox environments to ensure secure development workflows.

The Sandbox Security Auditor is a specialized tool designed to evaluate and strengthen the security posture of Claude Code Docker sandboxes. It systematically analyzes DevContainer configurations, firewall settings, and network isolation protocols to identify vulnerabilities like hardcoded secrets or overly permissive port exposures. By providing prioritized remediation steps and actionable reports, this skill helps developers prepare for production deployments, handle sensitive data safely, and maintain compliance with security best practices within containerized environments.
