Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install react-19-best-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 applies 49 React 19 rules ranked by impact and can audit a whole repository for duplicates, dead code and component boundaries. You get code aligned with current APIs rather than React 18 patterns.
