The key idea is simple:

You do not install the whole list.
You pick a skill and copy it into the right folder.

This guide shows you exactly how.

Also, if you want to scale this setup across teams, C# Corner Consulting can help you turn these skills into a shared, production-ready workflow.

Conceptual Background

It includes:

Both Claude and Codex follow the same idea.

Key Differences

Step-by-Step Walkthrough

Step 1: Install Codex CLI

Step 3: Create Skill Folder

---
name: repo-review
description: Review a code repository for issues and risks
---

Review the repo:

Codex uses it to decide when to run the skill

Move rules from CLAUDE.md → AGENTS.md

# Project rules

## Build
- npm test
- npm run lint

## Code style
- Keep changes small

## Review
