# Claude Code Workflow (CCW)

<div align="right">

**Languages:** [English](README.md) | [中文](README_CN.md)

</div>

A sophisticated multi-agent automation workflow framework that transforms complex software development tasks from conceptualization to implementation review into manageable, trackable, AI-orchestrated processes.

> **🎉 Major Architecture Upgrade (v2.0)**: Recently underwent comprehensive refactoring with **JSON-only data model**, **marker file session management**, and **unified complexity standards**. See [WORKFLOW_SYSTEM_UPGRADE.md](WORKFLOW_SYSTEM_UPGRADE.md) for details.

## 🏗️ Architecture Overview

Claude Code Workflow (CCW) is built on three foundational pillars:

### **JSON-Only Data Model**
- **Single Source of Truth**: All task states stored exclusively in `.task/impl-*.json` files
- **Dynamic Document Generation**: Markdown files generated on-demand as read-only views
- **Zero Synchronization**: Eliminates data consistency issues and sync complexity
- **Performance**: Direct JSON operations with <1ms query times

### **Marker File Session Management**
- **Ultra-Fast Operations**: Session switching through atomic file operations (`.workflow/.active-[session]`)
- **Self-Healing**: Automatic detection and resolution of session conflicts
- **Visual Management**: `ls .workflow/.active-*` shows current active session
- **Scalability**: Supports hundreds of concurrent sessions without performance degradation

### **Progressive Complexity**
CCW intelligently adapts its file structure and workflow processes based on unified task-count thresholds:
- **Simple workflows** (<5 tasks): Minimal structure, single-level hierarchy
- **Medium workflows** (5-15 tasks): Enhanced structure with progress tracking  
- **Complex workflows** (>15 tasks): Complete document suite with 3-level task decomposition

## 🚀 Core Features

### Multi-Agent System
- **Conceptual Planning Agent**: Multi-perspective brainstorming and concept planning
- **Action Planning Agent**: Converts high-level concepts into executable implementation plans
- **Code Developer**: Implements code based on plans
- **Code Review Agent**: Reviews code quality and compliance
- **Memory Gemini Bridge**: Intelligent CLAUDE.md documentation system with 4-layer hierarchy, context-aware updates, and automatic scaling based on project complexity

### Workflow Session Management
- Create, pause, resume, list, and switch workflow sessions
- Automatic initialization of required file and directory structures
- Hierarchical workflow filesystem (`.workflow/WFS-[topic-slug]/`)

### Intelligent Context Generation
- Dynamic context construction based on technology stack detection
- Project structure analysis and domain keyword extraction
- Optimized file targeting for Gemini CLI integration

### Dynamic Change Management
- Issue tracking and integration (`/workflow:issue`)
- Automatic re-planning capabilities (`/task:replan`)
- Seamless adaptation to changing requirements

## 📊 Complexity-Based Strategies

| Complexity | Task Count | Hierarchy Depth | File Structure | Command Strategy |
|------------|------------|----------------|----------------|------------------|
| **Simple** | <5 tasks | 1 level (impl-N) | Minimal structure | Skip brainstorming → Direct implementation |
| **Medium** | 5-15 tasks | 2 levels (impl-N.M) | Enhanced + auto-generated TODO_LIST.md | Optional brainstorming → Action plan → Progress tracking |
| **Complex** | >15 tasks | 3 levels (impl-N.M.P) | Complete document suite | Required brainstorming → Multi-agent orchestration → Deep context analysis |
