# Guard

Warnings on risky commands, edits kept inside your project folder

## What this does

You let an assistant run commands and change files on your machine, and you would rather it did not delete anything important or touch files far from your project. Switching this on adds two guardrails: commands that could destroy things come with a warning first, and file edits are kept inside one directory. Reach for it any time you want the help but not the exposure.

### Top 3 things it does for you

- Get warned before a destructive command runs
- Keep my file edits inside a single directory

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Guard

Handing an assistant control of your machine means living with two bad possibilities: a command that destroys something you needed, or an edit that lands somewhere unrelated. This is a full safety mode aimed straight at those two risks.

Destructive commands come with warnings, so you see trouble coming before it happens. File edits are scoped to a single directory, so changes stay where your work lives. Turn it on whenever you want the assistance without wondering what else got touched.

## Questions

### Is Guard safe to install?

AIR scanned this exact version of Guard and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 1cab5e11083a, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/guard.

### How do I install Guard?

Open https://airmarket.ai/app/guard on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/garrytan/gstack/tree/1cab5e11083a37ea0bc62117e9a9c5d05d68785e/guard. Install from that link, not the branch.
