Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install expo-performance-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 optimises an Expo app against 42 rules: bundle size and startup, list virtualisation, unnecessary re-renders, native or Reanimated animations, images and memory. It ranks the gains by impact. You get an app that runs more smoothly on modest devices.
