## Why Oh My Codex?

Codex CLI is powerful alone. **Oh My Codex makes it a team.**

| Codex CLI | Oh My Codex |
|-----------|-------------|
| Single agent | 32 specialized agents |
| Manual model selection | Auto model routing |
| Sequential execution | Parallel execution |
| No session memory | Session persistence |

Based on [Vercel's research](https://vercel.com/blog/agents-md-outperforms-skills-in-our-agent-evals): **AGENTS.md achieves 100% pass rate** vs 79% for skills-only.

## Installation

### Option 1: PyPI (Recommended)

```bash
pip install oh-my-codex
omx-setup  # Interactive setup wizard
```

### Option 2: pip with full orchestration

```bash
pip install "oh-my-codex[full]"  # Includes OpenAI Agents SDK
omx-setup
```

### Option 3: From Source

```bash
git clone https://github.com/junghwaYang/oh-my-codex.git
cd oh-my-codex
./install.sh
```

### Option 4: uv (fast)

```bash
uv pip install "oh-my-codex[full]"
omx-setup
```

### Requirements

- Python 3.10+
- [Codex CLI](https://github.com/openai/codex) installed (`npm i -g @openai/codex`)
- OpenAI API key or Codex Pro subscription

## Quick Start

```bash
# Basic usage (direct Codex)
omx "fix the bug in auth.py"

# Multi-agent autonomous execution
omx "autopilot: build a REST API with auth"

# Parallel execution
omx "ulw: refactor all components to TypeScript"

# Never give up mode
omx "ralph: fix all failing tests"
```

## Execution Modes

| Keyword | Mode | Description | Agents |
|---------|------|-------------|--------|
| `autopilot:` | Autopilot | Full autonomous execution | PM → Executor → Tester → Reviewer |
| `ulw:` | Ultrawork | Parallel multi-agent | PM + Frontend + Backend + Tester |
| `ultrapilot:` | Ultrapilot | Maximum parallelism | All specialists |
| `team:` | Team | Pipeline orchestration | plan → exec → verify → fix loop |
| `ralph:` | Ralph | Persistent (never gives up) | PM → Executor → Debugger |
| `plan:` | Plan | Planning only, no execution | Planner + Architect |
| `eco:` | Eco | Token-efficient, fast | Single Executor |
| `tdd:` | TDD | Test-driven development | Tester → Executor |
| `review:` | Review | Code review | Reviewer + Security |
| `debug:` | Debug | Systematic debugging | Debugger + Analyst |

### Examples

```bash
# Complex feature development
omx "autopilot: implement OAuth2 with Google and GitHub"

# Parallel refactoring
omx "ulw: convert all class components to hooks"

# Persistent bug fixing
omx "ralph: the login redirect isn't working, fix it"

# Architecture planning
omx "plan: design a microservices architecture"

# Quick fix (token-efficient)
omx "eco: add error handling to api calls"

# Test-driven development
omx "tdd: implement password validation"

# Security review
omx "review: audit the authentication module"
```

## Models & Reasoning

### Auto Model Selection

| Task Complexity | Model |
|-----------------|-------|
| Real-time | gpt-5.3-codex-spark |
| Simple | gpt-5-codex-mini |
| Standard | gpt-5.2-codex |
| Complex | gpt-5.3-codex |
| Long-running | gpt-5.1-codex-max |

### Reasoning Effort

| Level | Usage | Auto-mapped Modes |
|-------|-------|-------------------|
| `none` | Fast responses | eco |
| `low` | Light tasks | tdd, pipeline |
| `medium` | Balanced | plan, ultrawork |
| `high` | Deep thinking | autopilot, review |
| `xhigh` | Maximum (5.3-codex) | ralph, ultrapilot, debug |

```bash
# Manual override
omx --reasoning xhigh "complex architecture decision"
omx --model gpt-5.3-codex "critical task"
```

## Agents (32)

### Orchestration
| Agent | Model | Role |
|-------|-------|------|
| PM | gpt-5.3-codex | Master orchestrator, delegates tasks |
| Coordinator | gpt-5.3-codex | Manages parallel execution |

| DevOps | CI/CD, Docker, K8s |

### Quality
| Agent | Focus |
|-------|-------|
| Tester | Unit, integration, E2E tests |
| Reviewer | Code review, best practices |
| Security | Vulnerabilities, OWASP |
| Debugger | Systematic bug hunting |

### Specialized
| Agent | Domain |
|-------|--------|
| Architect | System design, patterns |
