SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides robust isolation for agent execution, ensuring security and resource management by leveraging various sandboxing technologies.

Core Features & Use Cases

  • Process Isolation: Runs agent code in secure, isolated environments like Docker, Kubernetes, or native OS sandboxes (nsjail, bwrap, seatbelt).
  • Resource Control: Enforces limits on memory, CPU, and network access for agent processes.
  • Use Case: Safely execute untrusted code or tools within an agent's workflow without risking system compromise, by deploying them within a Docker container or a Kubernetes pod.

Quick Start

Use the provider-sandbox skill to spawn a new process with the command 'ls -l /workspace' inside a Docker container.

FAQPage Schema
How do I securely execute untrusted agent code in an isolated Docker container?

To securely execute untrusted agent code in an isolated Docker container, use sandboxing technologies that enforce process isolation, zero network access, and read-only mounts for workspaces while managing lifecycles with configurable timeouts and memory limits.

What is the best way to isolate agent execution on Kubernetes with resource limits?

The best way to isolate agent execution on Kubernetes is by deploying pods that integrate with NATS for communication, enforcing security invariants like zero network access and read-only mounts while applying configurable memory and CPU limits.

Can I use native OS sandboxing tools like nsjail or bwrap for agent process isolation?

Yes, you can use native OS sandboxing tools like nsjail, bwrap, or seatbelt for agent process isolation across Linux and macOS, ensuring secure execution environments with strict resource and network controls.

How do I enforce zero network access and read-only mounts for a safe agent workflow?

You enforce zero network access and read-only mounts for a safe agent workflow by configuring the sandbox environment's security invariants, which prevent untrusted code from compromising the system during execution.

Does sandbox isolation support configurable timeouts and memory limits for agent processes?

Yes, sandbox isolation supports configurable timeouts and memory limits for agent processes, allowing you to manage process lifecycles and enforce strict resource control across Linux, macOS, and Kubernetes environments.
