# Before You Start

Build a dataset when you do not have real data yet

## What this does

Sometimes you need data to work with and none exists yet, or the real data cannot be used. This helps you make a dataset instead of hunting for one, either a one-off batch or a repeatable pipeline that keeps producing it. Reach for it when the work is blocked on not having data.

### Top 3 things it does for you

- Create a dataset from scratch
- Generate synthetic data
- Set up a data generation pipeline

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 Before You Start

This is for the moment when the work needs data and there is none. Ask for a dataset, ask for synthetic data, or ask for a pipeline that produces it, and this is the skill that picks up the request.

It covers both the one-off case and the ongoing one: a dataset you need now, and a generation pipeline you build once and keep using.

## Questions

### Is Before You Start safe to install?

AIR scanned this exact version of Before You Start and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 791254431fa0, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/data-designer.

### How do I install Before You Start?

Open https://airmarket.ai/app/data-designer on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up.
