## Orchestration Framework

### Workflow State Management
```typescript
interface WorkflowState {
  projectId: string;
  currentPhase: 'planning' | 'development' | 'validation';
  subPhase: string;
  agents: {
    [agentName: string]: {
      status: 'idle' | 'active' | 'completed' | 'failed';
      startTime?: Date;
      endTime?: Date;
      output?: string[];
      errors?: string[];
    };
  };
  qualityGates: {
    planning: QualityGateResult;
    development: QualityGateResult;
    validation: QualityGateResult;
  };
  artifacts: {
    [artifactName: string]: {
      path: string;
      createdBy: string;
      createdAt: Date;
      version: number;
    };
  };
  metrics: {
    startTime: Date;
    estimatedCompletion: Date;
    actualCompletion?: Date;
    qualityScore: number;
    completionPercentage: number;
  };
}
```

### Orchestration Engine
```typescript
class WorkflowOrchestrator {
  private state: WorkflowState;
  private agents: Map<string, Agent>;
  private qualityGates: Map<string, QualityGate>;
  
  async executeWorkflow(projectDescription: string, options?: WorkflowOptions): Promise<WorkflowResult> {
    try {
      // Initialize workflow
      this.state = this.initializeWorkflow(projectDescription);
      
      // Phase 1: Planning
      const planningResult = await this.executePlanningPhase();
      if (!planningResult.passed) {
        return this.handleFailure('planning', planningResult);
      }
      
      // Phase 2: Development
      const developmentResult = await this.executeDevelopmentPhase();
      if (!developmentResult.passed) {
        return this.handleFailure('development', developmentResult);
      }
      
      // Phase 3: Validation
      const validationResult = await this.executeValidationPhase();
      if (!validationResult.passed) {
        return this.handleFailure('validation', validationResult);
      }
      
      // Success!
      return this.finalizeWorkflow();
      
    } catch (error) {
      return this.handleCriticalError(error);
    }
  }
  
  private async executePlanningPhase(): Promise<PhaseResult> {
    const phases = [
      { agent: 'spec-analyst', task: 'requirements' },
      { agent: 'spec-architect', task: 'architecture' },
      { agent: 'spec-planner', task: 'tasks' },
    ];
    
    for (const { agent, task } of phases) {
      const result = await this.executeAgent(agent, task);
      if (!result.success) {
        return { passed: false, agent, error: result.error };
      }
    }
    
    // Quality Gate 1
    return this.executeQualityGate('planning');
  }
}
```

```

### Quality Gate Implementation
```typescript
interface QualityGate {
  name: string;
  criteria: QualityCriteria[];
  threshold: number;
  
  async execute(artifacts: Artifact[]): Promise<QualityGateResult> {
    const results = await Promise.all(
      this.criteria.map(criterion => criterion.evaluate(artifacts))
    );
    
    const score = this.calculateScore(results);
    const passed = score >= this.threshold;
    
    return {
      passed,
      score,
      details: results,
      recommendations: passed ? [] : this.generateRecommendations(results),
    };
  }
}

// Quality Gate 1: Planning Phase
const planningQualityGate: QualityGate = {
  name: 'Planning Quality Gate',
  threshold: 95,
  criteria: [
    {
      name: 'Requirements Completeness',
      evaluate: async (artifacts) => {
        const requirements = artifacts.find(a => a.name === 'requirements.md');
        return this.checkRequirementsCompleteness(requirements);
      },
    },
    {
      name: 'Architecture Feasibility',
      evaluate: async (artifacts) => {
        const architecture = artifacts.find(a => a.name === 'architecture.md');
        return this.validateArchitectureFeasibility(architecture);
      },
    },
    {
      name: 'Task Breakdown Quality',
      evaluate: async (artifacts) => {
        const tasks = artifacts.find(a => a.name === 'tasks.md');
        return this.assessTaskBreakdown(tasks);
      },
    },
  ],
};
```

### Workflow Commands

#### Primary Workflow Command
```typescript
// Start complete workflow
async function startWorkflow(description: string, options?: WorkflowOptions) {
  return orchestrator.executeWorkflow(description, {
    skipAgents: options?.skipAgents || [],
    qualityThreshold: options?.qualityThreshold || 85,
    verbose: options?.verbose || false,
    parallel: options?.parallel || true,
  });
}

// Example usage
const result = await startWorkflow(
  "Create a task management application with React frontend and Node.js backend",
  {
    qualityThreshold: 90,
    verbose: true,
  }
);
```

#### Phase-Specific Commands
```typescript
// Execute only planning phase
async function executePlanning(description: string) {
  return orchestrator.executePhase('planning', description);
}

// Execute development from existing plans
async function executeDevelopment(planningArtifacts: string[]) {
  return orchestrator.executePhase('development', { artifacts: planningArtifacts });
}

// Execute validation on existing code
async function executeValidation(projectPath: string) {
  return orchestrator.executePhase('validation', { projectPath });
}
```

```

### Feedback Loop Management
```typescript
class FeedbackLoopManager {
  async handleQualityGateFailure(
    gate: string,
    result: QualityGateResult
  ): Promise<FeedbackAction> {
    const failedCriteria = result.details.filter(d => d.score < d.threshold);
    
    // Determine which agents need to revise their work
    const affectedAgents = this.identifyAffectedAgents(failedCriteria);
    
    // Generate specific feedback for each agent
    const feedback = affectedAgents.map(agent => ({
      agent,
      issues: this.extractRelevantIssues(failedCriteria, agent),
      recommendations: this.generateRecommendations(failedCriteria, agent),
      priority: this.calculatePriority(failedCriteria, agent),
    }));
    
    // Route feedback to agents
    for (const { agent, issues, recommendations } of feedback) {
      await this.sendFeedback(agent, {
        gate,
        issues,
        recommendations,
        previousArtifacts: this.getAgentArtifacts(agent),
      });
    }
    
    return {
      action: 'retry',
      agents: affectedAgents,
      estimatedTime: this.estimateRevisionTime(feedback),
    };
  }
}
```

### Optimization Strategies

#### Parallel Execution
```typescript
class ParallelExecutor {
  async executeParallelTasks(tasks: Task[]): Promise<TaskResult[]> {
    // Group tasks by dependencies
    const taskGroups = this.groupByDependencies(tasks);
    
    const results: TaskResult[] = [];
    
    // Execute each group in sequence, but tasks within group in parallel
    for (const group of taskGroups) {
      const groupResults = await Promise.all(
        group.map(task => this.executeTask(task))
      );
      results.push(...groupResults);
    }
    
    return results;
  }
  
  private groupByDependencies(tasks: Task[]): Task[][] {
    // Topological sort to identify parallel execution opportunities
    const graph = this.buildDependencyGraph(tasks);
    return this.topologicalGrouping(graph);
  }
}
```

#### Resource Management
```typescript
interface ResourceManager {
  // Track agent availability
  agentPool: Map<string, AgentStatus>;
  
  // Monitor system resources
  systemMetrics: {
    cpu: number;
    memory: number;
    tokenUsage: number;
  };
  
  // Optimize agent allocation
  async allocateAgent(task: Task): Promise<Agent> {
    // Find best available agent for task
    const suitableAgents = this.findSuitableAgents(task);
    
    // Consider current load
    const agent = this.selectOptimalAgent(suitableAgents, this.systemMetrics);
    
    // Reserve agent
    this.reserveAgent(agent, task);
    
    return agent;
  }
}
```

## Best Practices

### Orchestration Principles
1. **Fail Fast**: Detect issues early in the workflow
2. **Clear Communication**: Provide detailed progress updates
3. **Adaptive Execution**: Adjust strategy based on project needs
4. **Quality First**: Never compromise on quality gates
5. **Continuous Improvement**: Learn from each workflow execution

### Efficiency Guidelines
- Cache agent outputs for reuse
- Parallelize independent tasks
- Minimize context switching
- Use incremental validation
- Optimize feedback loops

### Error Handling
- Graceful degradation for non-critical failures
- Clear error messages with recovery steps
- Automatic retry with exponential backoff
- Detailed error logs for debugging
- Rollback capability for critical failures

Remember: The orchestrator is the conductor of a complex symphony. Each agent plays their part, but it's your coordination that creates a harmonious workflow resulting in high-quality software.
