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

The cfa CLI is free and self contained. The PowerShell one-liner is the recommended install: it needs nothing else, no Node and no npm. Prefer npm? Use the second tab.

Install the CLI

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"

Update the CLI

Updating the CLI is separate from the plugin. cfa self-update knows how you installed it and does the right thing: a direct install replaces itself, an npm install runs npm for you.

powershell
cfa self-update

Works for both install methods: a direct install replaces itself, an npm install runs npm for you.

Refresh the AI skill afterward (restart your AI tool to reload it):

bash
cfa skill install

Knowing when to update

You do not have to keep checking. When a newer build is published, cfa mentions it once, and it does so wherever you actually work: in the terminal, and in the response your AI assistant reads, so an assistant can pass it on. The editor panel shows the same thing, with the CodeFizz toolbar icon turning amber. Nothing updates itself, it only tells you.

Ask at any time. Shows both versions, every install, and what each update is for:

bash
cfa check-updates

Prefer silence? Set CFA_NO_UPDATE_NOTIFIER=1 and cfa stops checking and stops mentioning it.
