# Command Bible Architecture Design
## Missing Commands Implementation Blueprint

### Executive Summary

This document provides the comprehensive architecture design for implementing the missing Command Bible commands in Gemini Flow v2.0.0. The design follows the established patterns from existing commands (task, sparc, swarm) while introducing specialized capabilities for execution, analysis, learning, generation, and analytics.

## Architecture Decision Records (ADRs)

### ADR-001: Command Integration Pattern
**Decision**: Use the existing Commander.js pattern with specialized agent orchestration
**Rationale**: Consistency with current codebase and proven scalability
**Implementation**: Each command extends the established Command class pattern with swarm coordination

### ADR-002: Execution Safety Model
**Decision**: Implement containerized execution with security boundaries
**Rationale**: Safe code execution requires isolation and resource management
**Implementation**: Docker/sandbox integration with resource limits

### ADR-003: ML Integration Strategy
**Decision**: Use Gemini API for pattern recognition with local cache
**Rationale**: Leverage existing AI capabilities while maintaining performance
**Implementation**: Hybrid cloud-local architecture

  private async generateStats(options: AnalyticsOptions) {
    const metrics = await this.metricsCollector.collect(options.timeframe);
    return this.reportGenerator.generateStatsReport(metrics);
  }
}
```

## Integration Patterns

### Gemini API Integration Pattern

```typescript
interface GeminiIntegration {
  // Code analysis and generation
  analyzeCode(code: string, context: ProjectContext): Promise<AnalysisResult>;
  generateCode(prompt: string, style: StyleProfile): Promise<GenerationResult>;
  
  // Pattern recognition
  recognizePatterns(codebase: Codebase): Promise<PatternAnalysis>;
  
  // Optimization suggestions
  suggestOptimizations(code: string, metrics: PerformanceMetrics): Promise<OptimizationSuggestions>;
}

class GeminiAPIAdapter implements GeminiIntegration {
  private client: GoogleGenerativeAI;
  private rateLimiter: RateLimiter;
  private cache: IntelligentCache;

  async analyzeCode(code: string, context: ProjectContext): Promise<AnalysisResult> {
    const prompt = this.buildAnalysisPrompt(code, context);
    const cached = await this.cache.get(prompt);
    
    if (cached) return cached;
    
    const result = await this.rateLimiter.execute(() =>
      this.client.generateContent(prompt)
    );
    
    await this.cache.set(prompt, result);
    return result;
  }
}
```

### File System Operation Patterns

```typescript
interface FileSystemOperations {
  // Safe file operations with validation
  safeRead(path: string): Promise<string>;
  safeWrite(path: string, content: string): Promise<void>;
  
  // Directory analysis
  analyzeStructure(basePath: string): Promise<ProjectStructure>;
  
  // Pattern matching
  findPatterns(basePath: string, patterns: string[]): Promise<FileMatch[]>;
}

class SecureFileSystem implements FileSystemOperations {
  private validator: PathValidator;
  private monitor: FileSystemMonitor;

  async safeRead(path: string): Promise<string> {
    // Validate path is within allowed boundaries
    await this.validator.validatePath(path);
    
    // Monitor for security threats
    this.monitor.trackAccess(path);
    
    return fs.readFile(path, 'utf8');
  }
}
```

### Memory Coordination Patterns

```typescript
interface MemoryCoordination {
  // Cross-command state management
  storeCommandState(command: string, state: CommandState): Promise<void>;
  retrieveCommandState(command: string): Promise<CommandState>;
  
  // Agent coordination
  shareAgentMemory(sourceAgent: string, targetAgent: string, memory: Memory): Promise<void>;
  
  // Context preservation
  preserveContext(contextId: string, context: ProjectContext): Promise<void>;
}

class DistributedMemoryManager implements MemoryCoordination {
  private storage: PersistentStorage;
  private coordinator: SwarmCoordinator;

  async storeCommandState(command: string, state: CommandState): Promise<void> {
    const key = `command:${command}:${Date.now()}`;
    await this.storage.store(key, state);
    
    // Notify other agents of state change
    await this.coordinator.broadcast('state_change', { command, key });
  }
}
```

## Error Handling and Safety Mechanisms

### Comprehensive Error Handling Architecture

```typescript
class CommandErrorHandler {
  private errorClassifier: ErrorClassifier;
  private recoveryStrategist: RecoveryStrategist;
  private notificationSystem: NotificationSystem;

  async handleError(error: Error, context: ExecutionContext): Promise<ErrorResponse> {
    // Classify error type and severity
    const classification = await this.errorClassifier.classify(error);
    
    // Attempt recovery based on error type
    const recovery = await this.recoveryStrategist.attemptRecovery(
      error, 
      classification, 
      context
    );
    
    // Notify relevant systems
    await this.notificationSystem.notify(classification, recovery);
    
    return {
      error: classification,
      recovery,
      recommendation: this.generateRecommendation(classification)
    };
  }
}
```

### Security Architecture

```typescript
class SecurityManager {
  private accessController: AccessController;
  private inputValidator: InputValidator;
  private executionSandbox: ExecutionSandbox;

  async validateExecution(command: string, parameters: any[]): Promise<SecurityCheck> {
    // Validate input parameters
    const inputValidation = await this.inputValidator.validate(parameters);
    
    // Check access permissions
    const accessCheck = await this.accessController.checkPermissions(command);
    
    // Ensure execution environment is secure
    const sandboxCheck = await this.executionSandbox.validateEnvironment();
    
    return {
      inputValid: inputValidation.valid,
      accessGranted: accessCheck.granted,
      sandboxSecure: sandboxCheck.secure,
      overallSecure: inputValidation.valid && accessCheck.granted && sandboxCheck.secure
    };
  }
}
```
