# AI prompts to get your game ready for hosting

> Each prompt is a block of plain text you paste into your AI coding assistant. It lists the facts about our servers, the exact changes to make and the proof to run. Start with the check, which tells you the one prompt that fits your game.

## How to use a prompt

1. Answer the five questions on [the check](https://netcraftgames.com/can-you-host-my-game/). It names the one prompt that fits.
2. Open that prompt, click inside the box to select the text and copy it. With JavaScript on there is also a copy button.
3. Paste it into your AI coding assistant, with your project open. Read what it changes.
4. Test with two real players. Then check again.

Every prompt tells the AI to make only the listed changes, never to put a secret in code, to run the proof steps and show the real output, and to stop and ask when something would need a redesign.

> **What "checked" means here**
>
> "Manifest checked" means the `ncg.json` settings inside the prompt pass the same validator the service uses, and every number in the text comes from the product's own constants. It does not mean an AI has followed the prompt and succeeded: that has not been measured yet. Prompts marked "Draft" also make claims about engine behaviour that no real build has proven.

| --- | --- | --- |

| [Unity: add a dedicated-server mode](https://netcraftgames.com/can-you-host-my-game/prompts/unity-dedicated/) | Makes your AI add a headless Linux server mode to a Unity project that uses Netcode for GameObjects or Mirror, and build it. | Manifest checked |
| [Unity: build the server I have for Linux](https://netcraftgames.com/can-you-host-my-game/prompts/unity-linux-build/) | For a Unity dedicated server that exists only for Windows or Mac: makes your AI build it for Linux x86-64. | Draft |

| [Node.js with Express or Fastify and WebSocket](https://netcraftgames.com/can-you-host-my-game/prompts/node-hosting-basics-generic/) | Same as the ws prompt, with the Express and Fastify details. | Manifest checked |


## What no prompt can do

A prompt cannot add multiplayer to a game that has none, cannot make a game that runs on an online service hostable, and cannot make Colyseus work through our gateway. The [check](https://netcraftgames.com/can-you-host-my-game/) says so before you start. The [glossary](https://netcraftgames.com/glossary/) explains the terms.
