Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install javascript-tree-shaking-dead-code

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 uses named ES imports and exports, checks module side effects, and helps the bundler drop unused exports at build time. You get lighter bundles with no dead code loaded for nothing.
