## 🚧 Issues Found

### 1. **Command Implementation Gap**
**Severity**: Medium  
**Description**: Most commands return "Not yet implemented"  
**Impact**: CLI is complete but backend functionality is missing  
**Status**: Expected for development version  

### 2. **Package Search Functionality**
**Severity**: Low  
**Description**: `search` command exists but doesn't actually search packages  
**Impact**: Users can't find available packages  
**Status**: Needs backend implementation  

### 3. **System Status Reporting**
**Severity**: Medium  
**Description**: `status` command doesn't provide system information  
**Impact**: Users can't determine current system state  
**Status**: Critical for basic functionality  

## 🎯 Development Priorities

   - Search available packages
   - Filter by package name/description
   - Show package metadata

3. **Implement `install` command**
   - Basic package installation
   - Dependency resolution
   - Transaction management

### **Phase 2: System Management (Medium Priority)**
1. **Implement `upgrade` command**
   - System upgrade functionality
   - Rollback capability
   - Update verification

2. **Implement `rollback` command**
   - Previous deployment restoration
   - Rollback verification
   - Boot management

3. **Implement `db` commands**
   - Package database queries
   - Repository information
   - Metadata access

### **Phase 3: Advanced Features (Low Priority)**
1. **Implement `compose` commands**
   - Tree composition
   - Package group management
   - Custom tree creation

2. **Implement `kargs` commands**
   - Kernel argument management
   - Boot parameter modification
   - Persistent changes

## 🔧 Technical Recommendations
