 **Claude Code Workflow (CCW)** is a next-generation multi-agent automation framework for software development that orchestrates complex development tasks through intelligent workflow management and autonomous execution.
 
-> **🎯 Latest Release v1.3**: Enhanced task decomposition standards, advanced search strategies with bash command combinations, free exploration phases for agents, and comprehensive workflow system improvements. See [CHANGELOG.md](CHANGELOG.md) for details.
+> **🎯 Latest Release v2.0**: Major architectural evolution with enhanced workflow lifecycle, Python-powered backend (`pycli`), comprehensive test workflow generation, plan verification system, and brainstorm artifacts integration. See [CHANGELOG.md](CHANGELOG.md) for details.
 
 ### 🌟 Key Innovations
 
-- **🧠 Intelligent Task Decomposition**: New core standards prevent over-fragmentation with functional completeness principles
+- **🔄 Enhanced Workflow Lifecycle**: Complete development cycle: Brainstorm → Plan → Verify → Execute → Test → Review
-- **🔍 Advanced Search Strategies**: Powerful command combinations using ripgrep, grep, find, awk, sed for comprehensive analysis
+- **🐍 Python-Powered Backend**: Advanced `pycli` integration with hierarchical vector database support for semantic context discovery
-- **⚡ Free Exploration Phase**: Agents can gather supplementary context after structured analysis
+- **🧪 Automated Test Generation**: Comprehensive test workflow generation (`/workflow:test-gen`) with full coverage planning
+- **✅ Plan Verification System**: Pre-execution validation using dual Gemini/Codex analysis (`/workflow:plan-verify`)
 - **🎯 JSON-First Architecture**: Single source of truth with atomic session management

-## ✨ Major Enhancements v1.3
+## ✨ Major Enhancements v2.0
 
-### 🎯 **Core Task Decomposition Standards**
+### 🔄 **Enhanced Workflow Lifecycle**
-Revolutionary task decomposition system with four core principles:
+Complete development lifecycle with quality gates at each phase:
 
-1. **🎯 Functional Completeness Principle** - Complete, runnable functional units
+1. **💡 Brainstorm Phase** - Multi-perspective conceptual planning with role-based analysis
-2. **📏 Minimum Size Threshold** - 3+ files or 200+ lines minimum
+2. **📋 Plan Phase** - Structured implementation planning with task decomposition
-3. **🔗 Dependency Cohesion Principle** - Tightly coupled components together
+3. **✅ Verify Phase** - Pre-execution validation using Gemini (strategic) + Codex (technical)
-4. **📊 Hierarchy Control Rule** - Flat ≤5, hierarchical 6-10, re-scope >10
+4. **⚡ Execute Phase** - Autonomous implementation with multi-agent orchestration
+5. **🧪 Test Phase** - Automated test workflow generation with comprehensive coverage
+6. **🔍 Review Phase** - Quality assurance and completion validation
 
-### 🔍 **Advanced Search Strategies**
+### 🐍 **Python-Powered Backend (`pycli`)**
-Powerful command combinations for comprehensive codebase analysis:
+Advanced semantic context discovery system:
 
 ```bash
-# Pattern discovery with context
+# Hierarchical vector database support
-rg -A 3 -B 3 'authenticate|login|jwt' --type ts --type js | head -50
+pycli --semantic-search "authentication patterns"
 
-# Multi-tool analysis pipeline
+# Auto-detects parent directory vector DB
-find . -name '*.ts' | xargs rg -l 'auth' | head -15
+pycli --context-discovery --inherit-parent
 
-# Interface extraction with awk
+# Intelligent file relevance scoring
-rg '^\\s*interface\\s+\\w+' --type ts -A 5 | awk '/interface/{p=1} p&&/^}/{p=0;print}'
+pycli --analyze-relevance "jwt token validation"
 ```
 
-### 🚀 **Free Exploration Phase**
+### 🧪 **Automated Test Generation**
-Agents can enter supplementary context gathering using bash commands (grep, find, rg, awk, sed) after completing structured pre-analysis steps.
+Comprehensive test workflow creation:
+- **Implementation Analysis**: Scans completed IMPL-* tasks for test requirements
+- **Multi-layered Testing**: Unit, Integration, E2E, Performance, Security tests
+- **Agent Assignment**: Specialized test agents for different test types
+- **Dependency Mapping**: Test execution follows implementation dependency chains
 
-### 🧠 **Intelligent Gemini Wrapper**
+### ✅ **Plan Verification System**
-Smart automation with token management and approval modes:
+Dual-engine validation before execution:
-- **Analysis Detection**: Keywords trigger `--approval-mode default`
+- **Gemini Strategic Analysis**: High-level feasibility and architectural soundness
-- **Development Detection**: Action words trigger `--approval-mode yolo`
+- **Codex Technical Analysis**: Implementation details and technical feasibility
-- **Auto Token Management**: Handles `--all-files` based on project size
+- **Cross-Validation**: Identifies conflicts between strategic vision and technical constraints
-- **Error Logging**: Comprehensive error tracking and recovery
+- **Improvement Suggestions**: Actionable recommendations before implementation begins
