Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install modern-javascript-practices

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 writes or reviews JavaScript and TypeScript code to current standards: ES2024 syntax, asynchronous programming, DOM manipulation and API integration with fetch. You get simpler, safer code with integration examples.
