# Nucleic Help Center

Everything you need to run agents safely — isolating them with Nucleic Control, sandboxing their work, and handing each one a whole virtual machine of its own. Pick a topic below.

## Nucleic Control

The hardened path where Nucleic clones, sandboxes, and observes a project directly — the foundation for unattended work, Autoship, and Orchestra.

What is Nucleic Control?→

What Control does, how to turn on the container service, and what it unlocks — sandboxed sessions, certain git observation, Autoship, and Orchestra.

## Sandboxes

Every sandboxed session runs in its own lightweight Linux VM — isolated from your host and from other sessions.

How agent sandboxing works→

What the sandbox is, what it isolates, the per-project options (idle timeout, host exec, custom images), and why the Swift toolchain lives in a VM instead.

## Virtual Machines

Give an agent a whole machine of its own — a per-session macOS or Linux VM for building, testing, and computer use, so parallel work never collides on your host.

Virtual machines: overview→

What macOS and Linux VMs are, the hardware and disk requirements, how per-session VMs are cloned and torn down, and how many run at once.

Building the base image→

The one-time golden base install: what the build does, choosing a guest macOS version, and pointing at a prebuilt bundle or a specific restore image.

Computer use: the two kinds→

Let an agent see and drive a VM's screen. The two kinds — kernel-level use and semantic understanding — what each does and when to reach for it.

Setting up AX-based computer useAdvanced→

The optional in-guest agent for semantic control — act on a UI element by identity, and inspect an app's accessibility tree. Fully automated on macOS 27.
