The AI Agent Sandbox That Takes 10 Seconds to Set Up

Sandboxing an AI agent doesn't have to be complicated.

Here's the 10-second setup:

Step 1: Create a folder 

mkdir C:i-workspaces   ask-1
Enter fullscreen mode Exit fullscreen mode

Step 2: Map it to a drive 

subst Z: C:i-workspaces    ask-1
Enter fullscreen mode Exit fullscreen mode

Step 3: Point the AI agent at it

Open Cursor / Claude Code / whatever tool you use, and point it at Z:\.

That's it. Done.

Why this works

Because it's an OS-level boundary. The filesystem enforces it, not the AI.

The agent can do whatever it wants inside that drive. It can't see anything outside of it.

The tool I use

The built-in subst command works, but mappings disappear when you reboot. I use ScsSubst (https://subst.scsoi.com/) to make them persistent. $9.99 lifetime, one-time purchase.

Compare to other setups

  • VM: 30 minutes to set up
  • Docker: 15 minutes to set up
  • Mapped drive: 10 seconds to set up

Same guarantee. 100x faster setup.

The bottom line

AI agent sandboxing doesn't have to be complicated. It's just a drive letter.

Spend 10 seconds setting it up. Save yourself hours of cleanup later.
