+# Changelog
+
+## [2.0.0] - 2025-11-23 - Major Architecture Overhaul
+
+### 🚀 Major Changes
+
+**Agent-Based Detection (vs Python Pattern Matching)**
+- Replaced 727-line `detect_project.py` Python script with intelligent `project-analyzer` agent
+- Agent reads key files, understands context, and asks clarifying questions
+- More accurate, context-aware project understanding
+
+**Interactive Workflow**
+- Added mode selection: Quick (⚡ $0.03, 10 min) → Focused (🔧 $0.10, 20 min) → Comprehensive (🏗️ $0.15, 30 min)
+- No more guessing - system asks questions with recommendations
+- Simple mode first for new users
+
+**Template-Based Generation**
+- Replaced Python string building with `.template` files using `{{variable}}` syntax
+- Easier to customize and maintain
+- Cleaner separation of structure from logic
+
+**Tool Discovery**
+- Automatically detects existing automation (linting, testing, CI/CD, git hooks, etc.)
+- Prevents duplication and integration conflicts
+- Recommends: fill gaps, enhance existing, or create independent
+
+**Cost Transparency**
+- Shows token estimates, time estimates, and costs BEFORE execution
+- No surprises - users see exactly what they're getting
+
+### 🎯 New Features
+
+**User Preference Learning** (`scripts/user_preferences.py`)
+- Tracks mode preferences, agent usage, satisfaction ratings
+- Provides personalized recommendations based on history
+- Calculates ROI: actual time saved / setup time
+
+**Metrics Tracking** (`scripts/metrics_tracker.py`)
+- Records ACTUAL time saved (not just estimates)
+- Tracks effectiveness: which automation is actually used
+- Proves value with real data
+
+**Rollback Capability** (`scripts/rollback_manager.py`)
+- Creates automatic backups before making changes
+- Manifest-based tracking of all changes
+- One-command rollback to pre-automation state
+
+**Configuration Reuse** (`scripts/agent_reuse.py`)
+- Saves successful automation configurations
+- Finds similar projects using similarity matching
+- Recommends reuse to save 5-10 minutes
+
+### 📁 New Scripts
+
+- `scripts/collect_project_metrics.py` - Simple metrics collection (150 lines vs 586)
+- `scripts/template_renderer.py` - Template rendering engine
+- `scripts/discover_existing_tools.py` - Existing automation detection
+- `scripts/cost_estimator.py` - Cost/time estimation
+- `scripts/user_preferences.py` - User learning and recommendations
+- `scripts/metrics_tracker.py` - Real usage tracking
+- `scripts/rollback_manager.py` - Backup and restore
+- `scripts/agent_reuse.py` - Configuration reuse
+
+### 📝 New Templates
+
+- `templates/agent-base.md.template` - Base template for agents
+- `templates/skill-base.md.template` - Base template for skills
+- `templates/command-base.md.template` - Base template for commands
+- `templates/project-analyzer.md` - Intelligent project analyzer agent
+
+### 🗑️ Removed
+
+**Obsolete Code:**
+- ❌ `scripts/detect_project.py` (727 lines) - Replaced by agent-based detection
+
+**Test Data:**
+- ❌ `.claude/meta-automation/` directories with test runs
+
+**Obsolete Documentation:**
+- ❌ `IMPROVEMENT_ROADMAP.md`
+- ❌ `PHASE1_IMPLEMENTATION.md`
+- ❌ `PHASE2_IMPLEMENTATION.md`
+- ❌ `PHASE3_IMPLEMENTATION.md`
+- ❌ `IMPLEMENTATION_COMPLETE.md`
+- ❌ `UNIVERSAL_UPGRADE.md`
+- ❌ `DOCUMENT_FORMATS_EXPANSION.md`
+
+**Old Templates:**
+- ❌ `templates/example-skill-template.md`
+- ❌ `templates/example-command-template.md`
+- ❌ `templates/example-hook-template.py`
+
+### 📊 Impact
+
+- **Lines Removed:** ~3,500 lines
+- **Files Removed:** ~18 files
+- **Code Quality:** Production-ready, maintainable structure
+- **User Experience:** Interactive, transparent, learns from usage
+- **Efficiency:** Simple mode first, progressive enhancement
+
+### 🔄 Migration Notes
+
+**Breaking Changes:**
+- `detect_project.py` removed - use `project-analyzer` agent instead
+- Old template format `{variable}` replaced with `{{variable}}`
+
+**New Workflow:**
+1. Skill asks: Quick, Focused, or Comprehensive?
+2. Collects project metrics
+3. Launches project-analyzer agent
+4. Agent analyzes and asks questions
+5. Discovers existing tools
+6. Shows cost/time estimates
+7. Generates automation
+8. Tracks usage and learns
+
+---
+
+## [1.0.0] - Initial Release
+
+- Universal project detection (8 project types)
+- 37 specialized agents
+- Skill, command, and hook generation
+- Coordinator architecture
+- Communication protocol
