Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install swiftui-preview-sample-data

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent produces realistic data, including the cases that break layouts such as empty lists, overflowing text and errors, then a set of #Previews covering light and dark mode, Dynamic Type, RTL and devices. You get code to place in your views and check the interface in the Xcode canvas.
