CodeFizz Editor Agent is a CodeFizz product. Payments processed by Polar Software, Inc. (Polar), the Merchant of Record.

Five commands, top to bottom. Run them in order and you are set up. The guides go deeper on each step, so you only need the basics here.

1

Install the CLI

Install the standalone cfa command. The PowerShell one-liner needs nothing else, no Node, no npm. Prefer npm? It is one tab over.

powershell
irm https://codefizz.dev/install.ps1 | iex

No Node or npm needed. From classic Command Prompt: powershell -c "irm https://codefizz.dev/install.ps1 | iex"

2

Sign in with your account

Activate this machine. cfa login opens your browser so you sign in with the same CodeFizz account as on the website. Details in License & Machines.

bash
cfa login
3

Install the plugin

Point at the engine you want it on. Other targets and version options are in Installing the Plugin.

bash
cfa install-plugin "E:/Unreal/UE_5.8"
4

Teach your AI the commands

Install the bundled skill so your assistant knows how to use cfa. Narrower scopes are in The AI Skill.

bash
cfa skill install
5

Open the editor and check the connection

Open your project in Unreal, then run this. The plugin is already signed in from step 2, so there is nothing to activate.

bash
cfa health_check
