About

Profile and fix React re-render thrash, slow lists, and expensive render paths

React Component Performance is a codex skill — a focused instruction set the agent loads when you need specialized coding help. Skills are lighter than full plugins and install with the --skill flag.

Source package path: Dimillian/Skills/react-component-performance on GitHub (Dimillian/Skills).

Key features

  • Specialized agent instructions for coding tasks
  • Lighter than a full plugin — focused playbook the agent loads on demand
  • Install with the --skill flag via npx
  • Ideal when you want React Component Performance expertise without a full integration

How to install

  1. 01

    Copy the install command

    Use the command on this page — it includes the correct --skill flag for this skill.

  2. 02

    Run it in your project terminal

    Execute the command from the directory where you use Codex, not necessarily your home folder.

  3. 03

    Restart or reload Codex

    Restart the Codex CLI or reload your IDE window so the new extension is picked up.

  4. 04

    Try an example prompt

    Ask Codex something related to React Component Performance to confirm the skill is active.

Example prompts

Try these after installing to confirm React Component Performance is working.

> This React list re-renders every second — profile it and isolate the ticking state
> Reduce re-renders on our dashboard without changing visible behavior
> Our table lags with 500 rows — suggest memoization and virtualization fixes

Requirements

  • Node.js 18 or newer with npx available
  • Codex CLI or IDE extension installed and signed in
