Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install react-component-performance-fixes

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 reproduces the slowdown, identifies what triggers re-renders, isolates fast-changing state and applies targeted fixes (memoization, stable callbacks, derived data). You get the changes and profiler verification steps.
