SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps developers run Claude Code and untrusted dependency workflows in an isolated container environment, reducing the risk of supply-chain attacks, credential exposure, and accidental host system changes.

Core Features & Use Cases

Containerized Agent Isolation: Creates a Docker Compose development environment where coding agents, package installs, and build tools run behind a default-deny network firewall.
Secure Development Workflow: Provides hardened Docker templates, firewall configuration, authentication guidance, and host/container separation patterns for safer autonomous coding.
Use Case: A developer can run npm installs, Rust builds, or Claude Code sessions inside a protected container while editing files from the host machine and preventing unauthorized network access or credential leakage.

Quick Start

Use the claude-code-docker-sandbox skill to create a hardened Docker Compose sandbox for running Claude Code and dependency installation safely.

FAQPage Schema

How do I securely run Claude Code in an isolated environment to prevent credential leakage?▼

You can securely run Claude Code by creating an isolated Docker Compose sandbox environment with restricted network access. This approach uses a default-deny network firewall and controlled egress allowlists to prevent credential leakage and protect the host system during autonomous coding sessions.

How do I sandbox untrusted package builds like npm installs to protect my host machine?▼

Sandbox untrusted package builds by executing npm installs or Rust builds inside a protected Docker container. This setup uses controlled egress allowlists and host/container separation patterns to prevent unauthorized network access and safeguard your host machine during dependency installation.

Can I edit files from my host machine while an autonomous coding agent runs inside a Docker container?▼

Yes, you can edit files from your host machine while a coding agent runs inside a Docker container. This secure development workflow uses hardened Docker templates and host/container separation patterns, allowing you to edit files locally while the agent operates in an isolated environment.

Does containerized agent isolation work with existing Docker Compose workflows?▼

Yes, containerized agent isolation integrates with Docker Compose workflows by applying hardened Docker templates and firewall configuration. It adds controlled egress allowlists to your existing development environment to provide reproducible and safer agent execution.

What are the limitations of using a Docker sandbox for coding agents?▼

A limitation of using a Docker sandbox is that it requires Docker Compose and careful firewall configuration, including controlled egress allowlists. If network restrictions are too strict, autonomous coding sessions may fail to access necessary external dependencies or APIs.
