Shows a simple risk level: Low / Medium / High (for reference)
Runs locally in your browser (no server-side storage)

Use this when

You’re about to run an AI-generated command and want a quick safety scan
You want to spot rm -rf, sudo, risky redirects, etc.
You need a last-minute check before running commands on a real machine

How to use

Open the tool
Paste the command(s) you plan to run (multi-line OK)
Read the risk level (Low/Medium/High) and the findings
If unsure, re-check targets/paths/privileges and test in a safe environment first

Tip: don’t start on production—test on a dummy folder/sandbox first.

Notes (limits)

This tool does not guarantee safety (reference only).
Variables, pipes, redirects, privileges, and working directory can change outcomes.
Static checks may miss environment-dependent or network-related risks.
For important operations, use backups and least-privilege practices.
