Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install react-rendering-bundle-optimization

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 profiles slow components, removes unnecessary re-renders, splits code with React.lazy and avoids barrel files. You get a diagnosis of bottlenecks and targeted optimizations.
