# Phase 6 Task 4: Configuration-Aware CLI Commands Implementation Plan
**Task Overview**: Implement CLI commands that respect and expose configuration
**Phase**: 6 - Configuration Foundation & CLI/TUI Parity
**Complexity**: Medium
**Priority**: High (Required for Phase 6 completion)
**Estimated Duration**: 3-4 days
## 🚨 **PRE-PRODUCTION PROJECT NOTICE**
**CRITICAL**: This is a PRE-PRODUCTION project. No backwards compatibility or migration support is required.
- **No Legacy Support**: Delete old files, configurations, or data structures freely
- **Breaking Changes OK**: Interface changes don't need migration paths
- **Clean Slate Approach**: Replace rather than extend existing implementations
- **No Production Users**: No need to maintain existing workflows
- **Delete and Recreate**: When restructuring, remove old embeddings/config and recreate fresh
## 🧪 **MANDATORY TESTING APPROACH**
**CRITICAL**: All tests MUST use real test data from `tests/fixtures/test-knowledge-base/`, not mocks!
### Testing Requirements
- **Use Real Test Data**: Tests must use files from `tests/fixtures/test-knowledge-base/`
- **No Mocks for Internal Logic**: Only mock external dependencies (APIs, databases, file system operations)
- **Expand Test Fixtures**: If your feature needs specific test scenarios, add real files to the test folder
- **Real File Operations**: Test actual file parsing, processing, and indexing with real documents
- **Authentic Test Scenarios**: Use realistic business documents that match actual use cases
## 🎯 **Task Goal**
Transform the CLI from a basic command interface into a **configuration-first, user-friendly management tool** that:
- Provides complete configuration management capabilities
- Accepts configuration overrides on every command
- Supports configuration profiles for different scenarios
- Delivers comprehensive help with configuration context
- Enables automation through JSON output
## 📋 **Success Criteria**
- [x] **Configuration Management**: Complete `config get/set/list/validate` command suite working ✅
- [x] **Universal Overrides**: All commands accept configuration overrides via CLI flags ✅
- [x] **Profile Management**: `profile` command working with named configuration profiles ✅
- [x] **Enhanced Help**: Help system shows configuration options and override capabilities ✅
- [x] **Automation Support**: JSON output option for scripting and automation ✅
- [x] **Real Testing**: All functionality tested with real configuration scenarios ✅
- [x] **Zero Regression**: No existing CLI functionality broken ✅
- [x] **Documentation**: Complete CLI configuration documentation ✅
## 🏗️ **MANDATORY ARCHITECTURAL PATTERNS**
### **🔧 DI ENFORCEMENT (In Every Assignment)**
```markdown
**🚨 MANDATORY DI PATTERN**:
1. **Interface First**: `domain/[feature]/I[Service].ts` - Pure interface, no implementation
2. **Constructor Injection**: `application/[feature]/[Service].ts` - All dependencies injected
3. **DI Registration**: `di/setup.ts` - Register interface → implementation mapping
4. **Zero Direct Instantiation**: NEVER use `new` outside DI container or tests
**VALIDATION AFTER EACH ASSIGNMENT**:
- [x] `npm run build` → MUST show 0 TypeScript errors
- [x] `grep "new [A-Z]" src/ --exclude-dir=di` → Should only show factories/DI
- [x] Interface in domain/, implementation in application/
- [x] Service registered in DI container
```
### **📐 Module Boundary Checks (After Every Assignment)**
```markdown
**✅ MODULE BOUNDARY VALIDATION**:
- [x] **Domain Layer**: Only interfaces, no implementations
- [x] **Application Layer**: Business logic with injected dependencies
- [x] **Infrastructure Layer**: External dependencies, no business logic
- [x] **Interface Layer**: Thin controllers/commands, delegates to application
- [x] **No Cross-Layer Violations**: Application never imports infrastructure
```

1. **Interface First**: `domain/cli/IConfigurationCommandService.ts` - Pure interface, no implementation
2. **Constructor Injection**: `application/cli/ConfigurationCommandService.ts` - All dependencies injected
3. **DI Registration**: `di/setup.ts` - Register interface → implementation mapping
4. **Zero Direct Instantiation**: NEVER use `new` outside DI container or tests
**Implementation**:
```typescript

2. **Constructor Injection**: `application/cli/ConfigurationOverrideService.ts` - All dependencies injected
3. **DI Registration**: `di/setup.ts` - Register interface → implementation mapping
4. **Zero Direct Instantiation**: NEVER use `new` outside DI container or tests
**Implementation**:
```typescript
// Global flags for all commands:
// --config <file> # Override config file location
// --profile <name> # Use specific profile
// --backend <backend> # Override embedding backend
