Overview

# Codex Workflow Skills

First-principles workflows for OpenAI Codex CLI. Built by developers who understand LLM limitations.

Who This Is For

Experienced developers frustrated by hype-driven AI coding tools. If you're tired of chasing the latest "game-changing" prompt that produces code you spend hours debugging, these skills offer a grounded alternative.

Our approach:

  • Workflows designed around how LLMs actually work, not how we wish they worked
  • Quality over speedβ€”invest upfront, ship with confidence
  • Simple to use, sophisticated under the hood

Installation

All Skills (Recommended)

Clone and copy all skills at once:

```bash

git clone https://github.com/doodledood/codex-workflow.git

cp -r codex-workflow/skills/* ~/.codex/skills/

```

Restart Codex to pick up new skills.
