- **QUICKSTART.md:** 5-minute setup guide
- **PROJECT_SUMMARY.md:** This file
### Scripts
- **setup.sh:** Automated setup and installation
- **verify.js:** Verification and testing script
## ✨ Key Features
### For End Users
✅ Natural language interface in Cursor
✅ No scripts to run - just ask in chat
✅ Both HTML and Markdown output
✅ Customizable time ranges
✅ Historical summary browsing
✅ Period comparisons for trend analysis
### For Developers
✅ Clean MCP protocol implementation
✅ Modular tool architecture
✅ Comprehensive error handling
✅ Environment-based configuration
✅ Debug mode support

## 🧪 Testing Results
Verification script passes with flying colors:
- ✅ Configuration loading works
- ✅ All 5 tools properly defined
- ✅ Tool handler routing works correctly
- ✅ Unknown tool handling works
- ✅ list_summaries tool functional
- ✅ Output directory creation works
- ⚠️ Only warnings: USER_NAME and USER_EMAIL not set (expected until .env configured)

## 🔄 Design Decisions
### 1. Instruction-Based Architecture
**Decision:** Server provides instructions, AI agent executes MCP calls
**Rationale:**
- Avoids complex MCP-to-MCP communication
- Leverages AI's natural language capabilities
- Simpler error handling and debugging
- More flexible and adaptable
### 2. Dual Output Formats
**Decision:** Generate both HTML and Markdown by default
**Rationale:**
- HTML for beautiful, interactive viewing
- Markdown for easy editing and sharing
- Minimal storage overhead (~60KB total)
- User flexibility
### 3. File-Based Storage
**Decision:** Save summaries to local files
**Rationale:**
- Simple and reliable
- No database dependencies
- Easy backup and sharing
- Human-readable formats
### 4. Tool Granularity
**Decision:** 5 focused tools instead of one monolithic tool
**Rationale:**
- Better discoverability in Cursor
- Faster execution for simple queries
- More composable with other tools
- Clearer intent and usage patterns
### 5. JSON Schema Validation
**Decision:** Comprehensive input schemas for all tools
**Rationale:**
- Clear API contracts
- Better error messages
- Auto-documentation in Cursor
- Type safety at tool boundaries
## 🚀 Usage Patterns
### Daily Check-in
```
"Get quick stats for today"
```
### Weekly Review
```
"Generate my weekly summary"
```
### Trend Analysis
```
"Compare this week to last week"
```
### Historical Lookup
```
"Show me my summary from October"
```
### Custom Reports
```
"Generate summary from Oct 1-7, markdown only, just achievements and todos"
```
