# ADR-003: Command Bible Implementation Strategy

## Status
Accepted

## Context
The Gemini Flow v2.0.0 platform needs to implement five critical missing commands from the Command Bible to achieve feature parity and complete the AI orchestration ecosystem. These commands (EXECUTE, ANALYZE, LEARN, GENERATE, ANALYTICS) represent core capabilities that users expect from a comprehensive AI development platform.

## Decision
We will implement the missing Command Bible commands using a hierarchical agent architecture with specialized swarm coordination, following the established patterns from existing commands while introducing new capabilities for execution safety, machine learning integration, and analytics.

## Architecture Principles

### 1. Consistency with Existing Patterns
- Follow the established Commander.js command structure
- Use the same TypeScript/Node.js technology stack
- Maintain compatibility with existing swarm orchestration
- Preserve the agent-based coordination model

### 2. Security-First Design
- Implement containerized execution environments
- Add comprehensive input validation
- Create resource usage limits and monitoring
- Establish audit trails for all operations

### 3. Performance Optimization
- Design for parallel execution where possible
- Implement intelligent caching strategies
- Optimize Gemini API usage with rate limiting
- Create efficient memory management patterns

### 4. Extensibility and Modularity
- Design modular components for easy extension
- Create plugin architectures for framework support
- Allow customizable templates and patterns
- Support multiple output formats and integrations

## Implementation Details

### Command Architecture Pattern

```typescript
// Base pattern followed by all commands
export abstract class BaseGeminiCommand extends Command {
  protected logger: Logger;
  protected swarmCoordinator: SwarmCoordinator;
  protected securityManager: SecurityManager;
  protected memoryManager: MemoryManager;

  constructor(name: string) {
    super(name);
    this.setupCommonInfrastructure();
  }

  protected async setupCommonInfrastructure() {
    // Common setup for all commands
    this.logger = new Logger(this.name());
    this.swarmCoordinator = SwarmCoordinator.getInstance();
    this.securityManager = new SecurityManager();
    this.memoryManager = new MemoryManager();
  }

  protected abstract validateInput(input: any): Promise<ValidationResult>;
  protected abstract executeCommand(input: any, options: any): Promise<CommandResult>;
  protected abstract handleError(error: Error, context: ExecutionContext): Promise<void>;
}
```

### Security Architecture

```typescript
interface SecurityBoundaries {
  // Execution isolation
  executionSandbox: {
    containerized: boolean;
    resourceLimits: ResourceLimits;
    networkIsolation: boolean;
    fileSystemRestrictions: string[];
  };

  // Input validation
  inputValidation: {
    typeChecking: boolean;
    rangeValidation: boolean;
    injectionPrevention: boolean;
    pathTraversalPrevention: boolean;
  };

  // Access control
  accessControl: {
    roleBasedAccess: boolean;
    commandPermissions: Map<string, Permission[]>;
    auditLogging: boolean;
  };
}
```

### Integration Architecture

```typescript
interface GeminiIntegrationLayer {
  // API management
  rateLimit: {
    requestsPerMinute: number;
    burstCapacity: number;
    backoffStrategy: 'exponential' | 'linear';
  };

  // Caching strategy
  cache: {
    layers: ['memory', 'disk', 'distributed'];
    ttl: Record<string, number>;
    invalidationStrategy: 'time-based' | 'event-based';
  };

  // Error handling
  errorRecovery: {
    retryAttempts: number;
    fallbackStrategies: string[];
    circuitBreaker: boolean;
  };
}
```
