# Task 7.2: Simplify Current Configuration System
**Phase**: 7 - Configuration System Overhaul
**Status**: 🚧 IN PROGRESS
**Created**: 2025-07-07
**Complexity**: Medium
**Approach**: Create transitional single JSON file system as stepping stone to new architecture
## 🚨 **MANDATORY ARCHITECTURAL REQUIREMENTS**
**⚠️ CRITICAL**: This task plan contains MANDATORY architectural patterns that MUST be followed throughout implementation. These patterns are embedded in every assignment to ensure consistency during long implementation sessions.
### **🏗️ DI ENFORCEMENT THROUGHOUT**
Every service/manager/repository created MUST follow this pattern:
1. **Interface First** (Domain Layer):
```typescript
// domain/[feature]/I[Service].ts
export interface IService {
method(): Promise<Result>;
}
```
2. **Constructor Injection** (Application Layer):
```typescript
// application/[feature]/[Service].ts
export class Service implements IService {
constructor(
private readonly dep1: IDep1,
private readonly dep2: IDep2
) {}
}
```
3. **DI Registration** (DI Layer):
```typescript
// di/setup.ts
container.register<IService>('IService', {
useClass: Service,
lifecycle: Lifecycle.Singleton
});
```
### **📐 Module Boundary Rules**
```
src/
├── domain/ # Interfaces ONLY - no implementations
├── application/ # Business logic with DI - no external dependencies
├── infrastructure/# External dependencies - no business logic
└── di/ # All service registrations - imports from all layers
```
### **✅ VALIDATION REQUIREMENTS (After EVERY Assignment)**
```bash
# 1. TypeScript MUST compile (ZERO errors)
npm run build
# Expected: "Found 0 errors"
# 2. Tests MUST pass
npm test -- tests/unit/[feature]
# Expected: All tests pass
# 3. DI Pattern Check
grep "constructor(" [new-service-file]
# Expected: Shows dependency parameters
# 4. No Direct Instantiation
grep -r "new [A-Z]" src/ --exclude-dir=di --exclude-dir=tests
# Expected: Only factories or DI container usage
# 5. Module Boundary Check
# Domain: Only interfaces
# Application: Business logic with DI
# Infrastructure: External deps only
# Interface: Thin layer, delegates to application
```
## 🎯 **Task Objective**
Move all current configurations to a single system-configuration.json file
## 🔍 **Pre-Implementation Checklist**
- [ ] Review existing code in: `src/config/`, `src/application/config/`, `src/infrastructure/config/`
- [ ] Identify reusable components: Current ConfigurationManager, validation logic
- [ ] Check for similar patterns in: Other JSON loading services
- [ ] Consider platform differences: File paths on Windows/Unix
- [ ] Review related tests: `tests/integration/cli/config-commands.test.ts`
## 📋 **Scope**
- [ ] Create system-configuration.json with ALL current configs
- [ ] Include both system and user-related configurations temporarily
- [ ] Simple JSON loader that reads this file on startup
- [ ] No hierarchy, no merging, no environment variables
- [ ] Write tests for simple JSON loading mechanism
## 📚 **Essential Project Context**
### From Completed Work
- Phase 1-5: MCP endpoints, file processing, TUI framework
- Phase 6: Built complex 6-source configuration system (now simplifying)
- Phase 7 Task 1: Removed all old configuration tests
- Current capabilities: 9 MCP endpoints, FAISS search, Ollama embeddings
### Critical Files to Understand
- `src/config/` - Current configuration system implementation
- `src/di/tokens.ts` - DI tokens for configuration services
- `src/interfaces/cli/commands/config.ts` - CLI config commands
- `src/application/services/FolderManager.ts` - Uses configuration
## 🔗 **Dependencies & Related Work**
### Prerequisite Tasks
- Phase 7 Task 1: Remove Old Configuration System Tests (✅ COMPLETED)
### Task Sequence
- **Previous**: Task 7.1 - Remove Old Configuration System Tests (removed test constraints)
- **Current**: Simplify Current Configuration System - Create transitional JSON system
- **Next**: Task 7.3 - Implement New User Configuration System - Build schema-driven system
## 📍 **Context from Roadmap**
### Related User Stories
- **As a user, I want simple configuration**: Just two YAML files with clear purpose
- **As a developer, I want clear separation**: System config vs user config with no overlap
### Configuration Requirements
#### User Configuration (config.yaml)
Not applicable for this task - this is transitional system only.
#### System Configuration (system-configuration.json)
- **Purpose**: Temporarily hold ALL configurations in one place
- **Location**: Project root or `~/.folder-mcp/`
- **Loading**: Simple JSON.parse() with no processing
- **No Schema**: This is transitional - schema comes in Task 7.3
#### Integration
- Replace complex ConfigurationManager with SimpleJsonConfigLoader
- All services continue to use configuration through DI
- No changes to service interfaces - only implementation
### Implementation Details
**Configuration Items to Move**:
- Model settings (modelName, batchSize, etc.)
- File processing settings (extensions, ignore patterns)
- Performance settings
- Development flags
- All other current configurations
## 🔧 **Implementation Assignments**
### Assignment 1: Analyze Current Configuration Usage ✅ COMPLETED
**Goal**: Map all configuration values currently in use
**Estimated Time**: 1 hour
**Actual Time**: 0.3 hours
**Completion Date**: 2025-07-07
#### **🚨 MANDATORY DI PATTERN FOR THIS ASSIGNMENT**:
Analysis only - no new services created.
#### Sub-tasks:
1. [x] **1.1 Find all configuration access points**
```bash
# Search for configuration usage
grep -r "config\." src/ --include="*.ts" | grep -v "test"
# Found: 34 files using config.* pattern
grep -r "getConfig\|configuration" src/ --include="*.ts"
# Found: 17 files using configuration manager
# Find DI token usage
grep -r "CONFIG_TOKENS" src/ --include="*.ts"
# Found usage in DI setup and services
```
2. [x] **1.2 Document current configuration structure**
```markdown
## Current Configuration Values:

3. [x] **1.3 Identify configuration dependencies**
```typescript
// Services that depend on configuration:
// - OllamaEmbeddingService: uses model settings (modelName, batchSize)
// - FolderManager: uses file patterns (extensions, ignorePatterns)
// - DaemonService: uses daemon config (all daemon settings)
// - ConfigurationManager: orchestrates all config sources
// - SmartDefaultsGenerator: generates defaults based on system capabilities
// - CacheStorage: uses cache settings
// - Logger: uses logLevel settings
// - MCP Server: uses server config
// - CLI Commands: use various configs for display/behavior
```
#### **✅ VALIDATION CHECKLIST**:
```bash
# Verify we found all config usage
grep -r "ConfigurationManager" src/ | wc -l
# Result: 17 files use ConfigurationManager
# Check for environment variable usage
grep -r "process\.env\.FOLDER_MCP" src/
# Result: Found env var expansion in config system
# Also found: ENABLE_ENHANCED_MCP_FEATURES for dev mode
```
#### **Implementation Notes**:
- Configuration system is highly complex with 6 sources
- Smart defaults system adapts to system capabilities
- Multiple config interfaces for different layers
- Heavy use of DI for configuration distribution
- Daemon config is comprehensive with health/restart/perf
#### **Completion Criteria**:
- [x] All configuration values documented
- [x] All consuming services identified
- [x] Default values captured
- [x] No configuration usage missed
**📝 Key Discoveries**:
- **Configuration Complexity**: The system has grown to include 8+ major config sections
- **Smart Defaults**: Sophisticated system that detects CPU, memory, GPU to set optimal values
- **Three-tier Performance**: Low/Medium/High tiers adjust batch sizes, concurrency, chunk sizes
- **Comprehensive Daemon Config**: Full process management with health checks, auto-restart, monitoring
- **Transport Flexibility**: Multiple transport options (stdio, local socket, remote, HTTP)
- **Development Flags**: Both config-based and env var-based development modes

### Assignment 2: Create system-configuration.json ✅ COMPLETED
**Goal**: Create single JSON file with all current configurations
**Estimated Time**: 1.5 hours
**Actual Time**: 0.2 hours
**Completion Date**: 2025-07-07
#### **🚨 MANDATORY DI PATTERN FOR THIS ASSIGNMENT**:
Not applicable - creating data file only.
#### Sub-tasks:
1. [x] **2.1 Create comprehensive JSON structure**
```json
// system-configuration.json created with all sections:
{
"model": { /* Processing configuration */ },
"fileProcessing": { /* File handling settings */ },
"server": { /* Server configuration */ },
"daemon": { /* Complete daemon config with health/restart/perf */ },
"ui": { /* UI/UX preferences */ },
"transport": { /* Transport layer config */ },
"cache": { /* Cache settings */ },
"development": { /* Dev flags */ },
"folders": { /* Folder defaults and list */ },
"systemCapabilities": { /* System detection */ },
"profiles": { /* Profile system (disabled) */ },
"metadata": { /* File metadata */ }
}
```
2. [x] **2.2 Include ALL configuration values**
```bash
# Included all 12 major configuration sections
# Added sensible defaults based on existing code
# Preserved smart defaults logic (will be removed later)
# Added metadata section for versioning
```
3. [x] **2.3 Place file in correct location**
```bash
# Created in both locations:
# 1. Project root: /Users/hanan/Projects/folder-mcp/system-configuration.json
# 2. User directory: ~/.folder-mcp/system-configuration.json
# SimpleJsonConfigLoader will use ~/.folder-mcp/ location
```
#### **✅ VALIDATION CHECKLIST**:
```bash
# Validate JSON syntax
npx jsonlint system-configuration.json
# Result: Valid JSON (fixed octal notation issue)
# Check all required fields present
node -e "const c = require('./system-configuration.json'); console.log(Object.keys(c))"
# Result: Shows all 12 top-level keys
```
#### **Completion Criteria**:
- [x] JSON file created with all configurations
- [x] Valid JSON syntax
- [x] All values from analysis included
- [x] Sensible defaults for all values
**📝 Key Discoveries**:
- **Comprehensive Config**: Created 12 major sections covering all discovered configs
- **Octal Notation**: JSON doesn't support octal (0o600), had to use decimal (384)
- **Flat Structure**: Kept relatively flat structure for easy JSON.parse()
- **Metadata Section**: Added for versioning and tracking
- **Both Locations**: Placed in project root and ~/.folder-mcp/ for flexibility

### Assignment 3: Implement System JSON Config Loader ✅ COMPLETED
**Goal**: Create minimal configuration loader that reads JSON file
**Estimated Time**: 2 hours
**Actual Time**: 0.3 hours
**Completion Date**: 2025-07-07
#### **🚨 MANDATORY DI PATTERN FOR THIS ASSIGNMENT**:
1. **Interface First**: Define `ISystemConfigLoader` in domain layer
2. **No Implementation Logic**: Interface must be pure contract
3. **Constructor Injection**: All dependencies injected
4. **Zero Direct Instantiation**: No `new` calls except in DI container
#### Sub-tasks:
1. [x] **3.1 Define interface in domain layer**
```typescript
// domain/config/ISystemConfigLoader.ts
export interface ISystemConfigLoader {
load(): Promise<any>;
get(path: string): any;
getAll(): any;
isLoaded(): boolean;
reload(): Promise<any>;
}
```
2. [x] **3.2 Implement in application layer**
```typescript
// application/config/SystemJsonConfigLoader.ts
import { ISystemConfigLoader } from '../../domain/config/ISystemConfigLoader';
import { IFileSystem } from '../../domain/infrastructure/IFileSystem';
export class SystemJsonConfigLoader implements ISystemConfigLoader {
private config: any = null;
private loaded: boolean = false;
constructor(
private readonly fileSystem: IFileSystem,
private readonly configPath: string
) {}
async load(): Promise<any> {
const content = await this.fileSystem.readFile(this.configPath);
this.config = JSON.parse(content);
this.loaded = true;
return this.config;
}
get(path: string): any {
if (!this.loaded) {
throw new Error('Configuration not loaded');
}
return this.getByPath(this.config, path);
}
getAll(): any {
if (!this.loaded) {
throw new Error('Configuration not loaded');
}
return JSON.parse(JSON.stringify(this.config)); // Deep copy
}
isLoaded(): boolean {
return this.loaded;
}
async reload(): Promise<any> {
this.loaded = false;
this.config = null;
return this.load();
}
private getByPath(obj: any, path: string): any {
// Supports dot notation and array[index] syntax
const keys = path.split('.');
let current = obj;
for (const key of keys) {
const arrayMatch = key.match(/^(\w+)\[(\d+)\]$/);
if (arrayMatch) {
const [, prop, index] = arrayMatch;
current = current?.[prop]?.[parseInt(index, 10)];
} else {
current = current?.[key];
}
}
return current;
}
}
```
3. [x] **3.3 Write comprehensive tests**
```typescript
// tests/unit/application/config/SystemJsonConfigLoader.test.ts
// Comprehensive test suite with 20 tests covering:
// - Load functionality (success, errors, invalid JSON)
// - Get operations (simple, nested, arrays, non-existent)
// - GetAll with deep copy protection
// - isLoaded state tracking
// - Reload functionality
// - Edge cases (empty config, null values, special characters)
```
#### **✅ VALIDATION CHECKLIST**:
```bash
# Check interface in domain layer
ls domain/config/ISystemConfigLoader.ts
# Result: File exists ✓
# Check implementation uses DI
grep "constructor(" application/config/SystemJsonConfigLoader.ts
# Result: Shows injected dependencies ✓
# Run tests
npm test -- tests/unit/application/config/SystemJsonConfigLoader.test.ts
# Result: All 20 tests pass ✓
```
#### **Completion Criteria**:
- [x] Interface defined in domain layer
- [x] Implementation in application layer
- [x] All dependencies injected
- [x] Comprehensive tests pass
- [x] No direct file system access
**📝 Key Discoveries**:
- **Naming**: Changed from "Simple" to "System" for clarity
- **Deep Copy**: Used JSON.parse(JSON.stringify()) for deep copy
- **Array Support**: Added support for array[index] notation
- **State Tracking**: Added isLoaded() and reload() methods
- **Edge Cases**: Handled null values, special characters in keys

### Assignment 4: Register in DI Container and Replace Old System
**Goal**: Wire up new loader in DI and replace complex ConfigurationManager
**Estimated Time**: 2 hours
#### **🚨 MANDATORY DI PATTERN FOR THIS ASSIGNMENT**:
1. **Container Registration**: Add to `di/setup.ts`
2. **Token Reuse**: Use existing CONFIG_TOKENS if possible
3. **Backward Compatibility**: Maintain same interface for consumers
4. **Lifecycle Management**: Singleton pattern for config
#### Sub-tasks:
1. [ ] **4.1 Register SystemJsonConfigLoader in DI**
```typescript
// di/setup.ts
import { SystemJsonConfigLoader } from '../application/config/SystemJsonConfigLoader';
// Replace old ConfigurationManager registration
container.registerSingleton(CONFIG_TOKENS.CONFIG_MANAGER, () => {
const fileSystem = container.resolve<IFileSystem>(INFRASTRUCTURE_TOKENS.FILE_SYSTEM);
const configPath = path.join(process.env.HOME || '', '.folder-mcp', 'system-configuration.json');
const loader = new SystemJsonConfigLoader(fileSystem, configPath);
// Load synchronously during DI setup
loader.load().catch(err => {
console.error('Failed to load configuration:', err);
process.exit(1);
});
return loader;
});
```
2. [ ] **4.2 Update configuration factory if needed**
```typescript
// di/factories/configurationFactory.ts
// Update to use SystemJsonConfigLoader interface
// Ensure backward compatibility
```
3. [ ] **4.3 Remove old configuration system files**
```bash
# Remove old complex configuration files
rm -f src/config/ConfigurationManager.ts
rm -f src/config/ConfigurationHierarchy.ts
rm -f src/config/ProfileManager.ts
rm -f src/config/EnvironmentLoader.ts
# Keep only what's needed for new system
```
#### **✅ VALIDATION CHECKLIST**:
```bash
# Verify DI registration
grep "SystemJsonConfigLoader" di/setup.ts
# Expected: Shows registration
# Check old files removed
ls src/config/ConfigurationManager.ts 2>/dev/null
# Expected: No such file
# Run application
npm run build && npm start
# Expected: Application starts with new config system
```
#### **Completion Criteria**:
- [ ] New loader registered in DI
- [ ] Old system files removed
- [ ] Application starts successfully
- [ ] All services get configuration
**📝 UPDATE AFTER COMPLETION**:
```markdown
### Assignment 4: Register in DI Container and Replace Old System ✅ COMPLETED

**Actual Time**: [X hours]
**Key Discoveries**: [What was learned during implementation]
```
---
### Assignment 5: Update CLI Commands and Verify System
**Goal**: Ensure CLI config commands work with new simple system
**Estimated Time**: 1.5 hours
#### **🚨 MANDATORY DI PATTERN FOR THIS ASSIGNMENT**:
CLI commands should resolve services through DI, not create directly.
#### Sub-tasks:
1. [ ] **5.1 Update config get command**
```typescript
// interfaces/cli/commands/config.ts
// Ensure it uses DI to get config loader
// Should work with dot notation paths
```
2. [ ] **5.2 Temporarily disable config set command**
```typescript
// Since we're using read-only JSON for now
// Add helpful message: "Configuration is read-only in this version"
// Will be re-enabled in Task 7.3
```
3. [ ] **5.3 Run integration tests**
```bash
# Run remaining config command tests
npm test -- tests/integration/cli/config-commands.test.ts
# Test manually
npx folder-mcp config get model.name
npx folder-mcp config get fileProcessing.extensions
npx folder-mcp config show
```
#### **✅ VALIDATION CHECKLIST**:
```bash
# Test config get command
npx folder-mcp config get model.name
# Expected: Shows value from system-configuration.json
# Test config show command
npx folder-mcp config show
# Expected: Displays entire configuration
# Run integration tests
npm test -- tests/integration/cli/config-commands.test.ts
# Expected: Get/show tests pass (set tests may need updates)
```
#### **Completion Criteria**:
- [ ] Config get command works
- [ ] Config show command works
- [ ] Integration tests updated
- [ ] No regression in functionality
**📝 UPDATE AFTER COMPLETION**:

#### **🎯 Context-Aware Validation Commands**
**Build & Core Validation** (Always Required):
```bash
npm run build
# Expected: "Found 0 errors"
npm test
# Expected: All tests pass
```
**DI/Architecture Tasks Only**:
```bash
# Verify dependency injection patterns
grep -r "new [A-Z]" src/ --exclude-dir=di --exclude-dir=tests
# Expected: Only factories, builders, or test fixtures
# Check service registration
grep "SystemJsonConfigLoader" src/di/setup.ts
# Expected: Service properly registered in DI container
```
**System Configuration Tasks Only**:
```bash
# Test configuration loading
cat ~/.folder-mcp/system-configuration.json | jq .
# Expected: Valid JSON with all config values
# Verify app uses new config
npx folder-mcp config get model.name
# Expected: Shows value from JSON file
```
**CLI/Commands Tasks Only**:
```bash
# Test configuration commands
npx folder-mcp config get model.name
# Expected: Shows correct value
# Test config show
npx folder-mcp config show
# Expected: Displays full configuration
```
## 🔄 **Phase Plan Update Process**
### When to Update Phase Plan
The phase plan MUST be updated when:
1. **Task Completion**: When marking a task as ✅ COMPLETE
2. **Before Commit**: After human review confirms task is complete
3. **Creating Next Task**: When previous task wasn't marked complete
### Phase Plan Update Instructions
When a task is marked complete, update the phase plan (`Phase-7-configuration-system-overhaul-plan.md`):
#### 1. **Update Phase Tasks Overview Table**
```markdown
| Task # | Task Name | Complexity | Status | Command |
|--------|-----------|------------|--------|---------|
| 1 | Remove Old Configuration System Tests | Low | ✅ | ~~`/create-task-plan 7 1`~~ |
| 2 | Simplify Current Configuration System | Medium | ✅ | ~~`/create-task-plan 7 2`~~ |
| 3 | Implement New User Configuration System | High | ⏳ | `/create-task-plan 7 3` |
```
#### 2. **Update Phase Completion Log**
```markdown
### **Phase Completion Log**
| Task | Status | Completion Date | Key Decisions/Findings |
|------|--------|-----------------|------------------------|
| Task 1: Remove Old Configuration System Tests | ✅ | 2025-07-07 | Removed 11 test files |
| Task 2: Simplify Current Configuration System | ✅ | 2025-07-XX | Single JSON file approach |
```
#### 3. **Update Progress Metrics**
```markdown
### **Linear Progress Bar**
```
■■□□□□ 2/6 Tasks (33%)
```
```
## 📋 **Configuration Pattern Examples**
### System Configuration Pattern (Direct JSON)
```json
// system-configuration.json
{
"model": {
"name": "all-minilm-l6-v2",
"batchSize": 32
},
"fileProcessing": {
"extensions": [".txt", ".md", ".pdf"],
"maxFileSize": 10485760
}
}
```
Result: Internal only, no UI, loaded at startup
### Simple JSON Loader Pattern
```typescript
// No schema validation
// No type safety (yet)
// Just JSON.parse() and go
const config = await loader.load();
const modelName = config.model.name;
```
## 🔄 **Actionable Input Integration Workflow**
When human feedback is received during task review, follow this workflow:
### 1. **Categorize Feedback**
```markdown
## Human Feedback Received: [Date]
### Immediate Action Items (Address Before Continuing)
- [ ] [Feedback item that must be fixed now]
- [ ] [Another immediate issue]
### Future Phase Items (Address Later)
- [ ] [Feedback for future consideration]
- [ ] [Enhancement suggestion for later phase]
### Clarification Needed
- [ ] [Question that needs human clarification]
```
### 2. **Update Plans Before Resuming**
**For Immediate Items**: Update this task plan with new assignments
**For Future Items**: Add to Phase plan or roadmap
**For Clarifications**: Document questions and wait for answers
### 3. **Implementation Strategy**
```markdown
## Feedback Integration Plan
### How Immediate Items Will Be Addressed:
1. [Describe approach for first immediate item]
2. [Describe approach for second immediate item]
### Timeline Impact:
- Original estimate: X hours
- Additional work: Y hours
- New total: Z hours
### Dependencies Created:
- [What this feedback creates as dependencies for future work]
```
### 4. **Resume Coding Only After Planning**
- ✅ All immediate feedback categorized
- ✅ Implementation approach planned
- ✅ Timeline updated
- ✅ Dependencies documented
- ✅ Human confirmation received (if needed)
**CRITICAL**: Never resume implementation until the feedback has been properly planned and the human has confirmed the approach.
