🌟 Major Features & Enhancements

🏗️ Four-Layer Architecture (NEW)

CCW now operates through four distinct architectural layers with defined responsibilities and data contracts:

Layer	Components	Data Flow	Integration Points
🖥️ Interface Layer	CLI Commands, Gemini/Codex/Qwen Wrappers	User input → Commands → Agents	External CLI tools, approval modes
📋 Session Layer	.active-[session] markers, workflow-session.json	Session state → Task discovery	Atomic session switching
📊 Task/Data Layer	.task/impl-*.json, hierarchy management	Task definitions → Agent execution	JSON-first model, generated views
🤖 Orchestration Layer	Multi-agent coordination, dependency resolution	Agent outputs → Task updates	Intelligent execution flow

🔄 Enhanced Workflow Lifecycle

Complete development lifecycle with quality gates at each phase:

1. 💡 Brainstorm Phase - Multi-perspective conceptual planning with role-based analysis
2. 📋 Plan Phase - Structured implementation planning with task decomposition
3. ✅ Verify Phase - Pre-execution validation using Gemini (strategic) + Codex (technical)
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

🧪 Automated Test Generation

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

✅ Plan Verification System

Dual-engine validation before execution:

• Gemini Strategic Analysis: High-level feasibility and architectural soundness
• Codex Technical Analysis: Implementation details and technical feasibility
• Cross-Validation: Identifies conflicts between strategic vision and technical constraints
• Improvement Suggestions: Actionable recommendations before implementation begins

🧠 Smart Tech Stack Detection

Intelligent task-based loading of technology guidelines:

• Automatic Detection: Only loads tech stacks for development and code review tasks
• Multi-Language Support: TypeScript, React, Python, Java, Go, JavaScript
• Performance Optimized: Skips detection for non-relevant tasks
• Context-Aware: Applies appropriate tech stack principles to development work

🔮 Qwen CLI Integration

Full integration of Qwen CLI for architecture analysis and code generation:

• Architecture Analysis: System design patterns and code quality assessment
• Code Generation: Implementation scaffolding and component creation
• Intelligent Modes: Auto template selection and precise architectural planning
