# Prototype

Answer design questions with code you never meant to keep

## What this does

You are stuck on a design choice and more discussion is not settling it: whether the way you plan to arrange things inside the app makes sense, or what a screen should actually look like. This builds a rough version just to find out. Nothing in it is precious, because it was made to be thrown away afterwards. You walk away knowing whether the idea works.

### Top 3 things it does for you

- Sanity-check whether a state model or piece of logic feels right
- Explore what an interface should look like
- Try an idea in rough form before building it properly

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 Prototype

Some design questions cannot be settled by talking about them. Whether a state model or a piece of logic feels right, or what an interface should look like, is easier to judge when there is something in front of you. This builds a quick, throwaway prototype to answer that one question.

Reach for it when you are still deciding, not yet committed. The code it produces is not meant to survive into the finished product; the point is what you learn from it.

## Questions

### Is Prototype safe to install?

AIR scanned this exact version of Prototype and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 885e2ca4d842, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/prototype.

### How do I install Prototype?

Open https://airmarket.ai/app/prototype 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/mattpocock/skills/tree/885e2ca4d842d139e9aef4e48d366c63cb1b8013/skills/engineering/prototype. Install from that link, not the branch.
