async executeWorkflow(projectDescription: string, options?: WorkflowOptions): Promise<WorkflowResult> {
try {
// Initialize workflow
this.state = this.initializeWorkflow(projectDescription);
// Phase 1: Planning

Quality Gate Implementation
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
// 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
// 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
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
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
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
- Fail Fast: Detect issues early in the workflow
- Clear Communication: Provide detailed progress updates
- Adaptive Execution: Adjust strategy based on project needs
- Quality First: Never compromise on quality gates
- 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.
