PactKit PDCA workflow framework adapted for OpenAI Codex CLI

pactkit-codex

PactKit PDCA workflow framework adapted for OpenAI Codex CLI.

What is this?

pactkit-codex brings the PactKit spec-driven development workflow to OpenAI's Codex CLI. It deploys:

• AGENTS.md — Global constitution with agent roles and PDCA routing
• Command prompts — 10 PDCA workflow commands (/project-plan, /project-act, etc.)
• Skills — Standalone Python scripts (visualize, board, scaffold)
• Rules — Modular governance rules loaded on-demand per command

Installation

pip install pactkit-codex

Quick Start

# Deploy PactKit configuration to ~/.codex/
pactkit-codex init

# Update when pactkit-codex is upgraded
pactkit-codex update

# Check version
pactkit-codex version

Commands

Initialization

pactkit-codex init                    # Full deployment
pactkit-codex init -t /tmp/preview    # Deploy to custom directory

Update

pactkit-codex update                  # Incremental update (if version changed)
pactkit-codex update --if-needed      # Silent no-op if current (for hooks)
pactkit-codex update --force          # Force redeploy even if current
pactkit-codex update --dry-run        # Show what would change

Utilities

pactkit-codex version                 # Show version
pactkit-codex spec-lint <file>        # Validate spec structure
pactkit-codex doctor                  # Check project health
pactkit-codex visualize --lazy        # Generate code dependency graphs

PDCA Workflow Commands

Once deployed, use these commands in Codex CLI:

Command	Phase	Purpose
/prompts:project-init	Bootstrap	Initialize project governance
/prompts:project-design	Plan	Greenfield product design
/prompts:project-plan	Plan	Break down requirements into specs
/prompts:project-act	Act	Implement code per spec (TDD)
/prompts:project-check	Check	QA verification
/prompts:project-done	Done	Finalize and document
/prompts:project-release	Done	Version release
/prompts:project-pr	Done	Create pull request
/prompts:project-hotfix	Act	Quick fix bypass
/prompts:project-clarify	Plan	Clarify requirements

Codex CLI vs Claude Code

This project adapts PactKit for Codex CLI, which has different capabilities:

Feature	Claude Code	Codex CLI	pactkit-codex Solution
Multi-agent	Native	Single agent	Prompt-level role conventions
Custom commands	/project-*	/prompts:*	Deploy to ~/.codex/prompts/
Rule loading	@import	None	Agentic routing (Prerequisites header)
Config	settings.json	config.toml	Generate with defaults

Configuration

pactkit.yaml

stack: python          # Detected automatically
version: 0.0.1         # Your project version
root: .
developer: ""          # Optional: your name prefix for Story IDs

Custom Instructions

Add your project-specific instructions to .codex/AGENTS.local.md:

# Project Local Instructions

## Build Commands
- Run tests: `pytest tests/ -v`
- Lint: `ruff check src/`

## Project Conventions
- Use snake_case for Python
- All APIs must have OpenAPI docs

This file is never overwritten by pactkit-codex updates.
