Get started

You need a SteamOS device running Decky Loader 3.3 or newer, and VS Code 1.90+ or VSCodium on your computer.

1. Install the extension

Search for Decky Toolkit in the Extensions view, or install it from a terminal:

code --install-extension jackhric.decky-toolkit     # VS Code
codium --install-extension jackhric.decky-toolkit   # VSCodium

The extension is on the VS Code Marketplace and Open VSX.

2. Install the plugin on your SteamOS device

1. In Decky’s settings, turn on General → Other → Developer mode.

2. Open Developer → Third-Party Plugins → Install Plugin from URL and enter:

   jackhric.github.io/decky-toolkit/decky-toolkit.zip

3. Decky warns about third-party plugins (Continue unlocks after a few seconds), then asks you to confirm.

Open Quick Access (…) → Decky Toolkit. The panel shows the device’s IP address.

3. Pair your editor

1. Click the Decky icon in the Activity Bar, then Add device, and enter the IP address.
2. Click the device. The editor shows a four-digit code.
3. The device shows a toast with the same code. In Quick Access → Decky Toolkit, check the code and press Approve.

The token never has to be typed in. A request waits as long as the editor is waiting.

4. Deploy your plugin

Open your plugin’s folder (any folder with a plugin.json) and press Ctrl+Alt+D. See Hot reload your plugin for what happens.
