Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install npm-package-exports-publishing

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 sets the exports field and entry points in package.json, produces ESM and CJS builds with their types, then publishes with provenance. You get a package that resolves correctly in every environment.
