Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install universal-build-plugins-unplugin

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 creates or integrates an Unplugin plugin: the createUnplugin factory, hooks and context, filters, nested plugins and bundler-specific behaviour. It also helps diagnose hooks that act differently from one tool to another. You get a plugin that is portable across bundlers.
