# Idempotent Script Design

Run it twice and the second run does no damage

## What this does

Automated things get run more than once, on purpose or by accident, and a careless script does its work twice. This shapes each operation so a repeat run leaves you where the first one did. Reach for it when writing anything on a schedule, or anything you might have to re-run after a failure.

### Top 3 things it does for you

- Write a script that is safe to re-run
- Keep a cron job from doubling its work
- Check a pipeline for repeat-run damage

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 Idempotent Script Design

This applies while you are writing scripts, cron jobs, data pipelines, or any process that runs on its own and may run more than once.

The aim is that every operation is safely re-runnable: running it again does not produce side effects on top of the ones already there.

## Questions

### Is Idempotent Script Design safe to install?

AIR scanned this exact version of Idempotent Script Design and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit fc163ba8a12b, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/idempotent-script-design.

### How do I install Idempotent Script Design?

Open https://airmarket.ai/app/idempotent-script-design 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/aiming-lab/MetaClaw/tree/fc163ba8a12ba5e6950544c3e0d55707c16e2a7e/memory_data/skills/idempotent-script-design.
