Quick Setup

# Basic workflow setup
from alfred_workflow import WorkflowEngine, Agent

engine = WorkflowEngine()
spec_agent = Agent("spec-builder", domain="requirements")
impl_agent = Agent("tdd-implementer", domain="development")
test_agent = Agent("quality-gate", domain="testing")

workflow = engine.create_workflow("feature_development")
workflow.add_stage("specification", spec_agent)
workflow.add_stage("implementation", impl_agent, depends_on=["specification"])
workflow.add_stage("testing", test_agent, depends_on=["implementation"])
result = engine.execute(workflow, input_data={"feature": "user auth"})

# Context7 integration
from alfred_workflow import Context7Integration

context7 = Context7Integration()
examples = context7.search_code_examples(
    query="react authentication", language="javascript", framework="react"
)
best_practices = context7.get_best_practices(
    topic="database optimization", database="postgresql"
)

Essential Patterns

Level 2: Core Implementation

Architecture Overview

WorkflowEngine: Central orchestrator managing agents and workflows Agent System: Specialized agents for different domains (spec-builder, tdd-implementer, quality-gate) Task Model: Structured tasks with dependencies, priorities, and retry logic Template System: Reusable workflow patterns (feature development, bug fix)

Level 3: Advanced Features

Workflow Scheduling

from enum import Enum
import uuid
import asyncio

class WorkflowPriority(Enum):
    LOW = 1
    MEDIUM = 2  
    HIGH = 3
    CRITICAL = 4

class WorkflowScheduler:
    def __init__(self, workflow_engine: WorkflowEngine):
        self.workflow_engine = workflow_engine
        self.workflow_queue = asyncio.Queue()
        self.template_manager = WorkflowTemplateManager()
        
    async def submit_workflow(self, template_name: str, config: Dict,
                            priority: WorkflowPriority = WorkflowPriority.MEDIUM,
                            scheduled_time: Optional[datetime] = None) -> str:
        workflow_id = str(uuid.uuid4())
        
        workflow = self.template_manager.create_workflow_from_template(
            template_name, self.workflow_engine, config
        )
        
        if not workflow:
            raise ValueError(f"Unknown template: {template_name}")
        
        workflow_item = {
            'workflow_id': workflow_id,
            'workflow': workflow,
            'priority': priority,
            'scheduled_time': scheduled_time or datetime.now()
        }
        
        await self.workflow_queue.put((-priority.value, workflow_item))
        return workflow_id

Error Handling & Recovery

class WorkflowErrorHandler:
    def __init__(self, workflow_engine: WorkflowEngine):
        self.workflow_engine = workflow_engine
    
    async def handle_task_failure(self, task: Task, error: Exception) -> bool:
        if task.retry_count < task.max_retries:
            return await self._retry_with_backoff(task, error)
        
        if self._is_retriable_error(error):
            return await self._retry_with_backoff(task, error)
        else:
            return await self._require_manual_intervention(task, error)
    
    async def _retry_with_backoff(self, task: Task, error: Exception) -> bool:
        delay = 2 ** task.retry_count
        task.retry_count += 1
        await asyncio.sleep(delay)
        
        try:
            await self.workflow_engine.execute_task(task)
            return True
        except Exception as e:
            return await self.handle_task_failure(task, e)
    
    def _is_retriable_error(self, error: Exception) -> bool:
        retriable_errors = ['TimeoutError', 'ConnectionError', 'TemporaryFailure']
        return type(error).__name__ in retriable_errors

Performance Monitoring

class WorkflowMetrics:
    def __init__(self):
        self.metrics = {
            'workflows_completed': 0,
            'workflows_failed': 0, 
            'total_execution_time': 0.0,
            'task_completion_times': []
        }
    
    def record_workflow_completion(self, workflow_id: str, execution_time: float, status: str):
        if status == 'completed':
            self.metrics['workflows_completed'] += 1
        else:
            self.metrics['workflows_failed'] += 1
        
        self.metrics['total_execution_time'] += execution_time
    
    def get_performance_summary(self) -> Dict[str, Any]:
        completed = self.metrics['workflows_completed']
        failed = self.metrics['workflows_failed']
        total = completed + failed
        
        if total == 0:
            return {'error': 'No workflows executed'}
        
        avg_time = self.metrics['total_execution_time'] / total if total > 0 else 0
        success_rate = (completed / total) * 100 if total > 0 else 0
        
        return {
            'total_workflows': total,
            'success_rate': f"{success_rate:.2f}%",
            'average_execution_time': f"{avg_time:.2f}s",
            'workflows_completed': completed,
            'workflows_failed': failed
        }

Level 4: Reference & Integration

When to Use

Use for:

• Multi-agent workflows requiring coordination
• Automated CI/​CD pipelines with intelligent decision making
• Enterprise process automation with error handling
• Tasks requiring Context7 integration for best practices
• Workflows needing comprehensive monitoring

Avoid for:

• Simple single-agent tasks (use specific domain skills)
• Basic automation without coordination needs
• Quick prototyping without enterprise requirements

Common Usage Patterns

# Feature Development Workflow
workflow_id = await scheduler.submit_workflow(
    "feature_development",
    {
        "feature_name": "user_authentication",
        "feature_description": "Implement secure user login",
        "requirements": ["JWT auth", "Password hashing"],
        "acceptance_criteria": ["Users can login securely"]
    }
)

# Bug Fix Workflow  
bug_workflow_id = await scheduler.submit_workflow(
    "bug_fix",
    {
        "bug_id": "BUG-001",
        "bug_description": "Login fails with invalid credentials",
        "error_logs": ["AuthException at line 42"],
        "reproduction_steps": ["Enter invalid password"]
    },
    priority=WorkflowPriority.HIGH
)

Security & Compliance

TRUST Principles Applied:

• Test First: All workflows include validation stages and quality gates
• Readable: Clear workflow structure with comprehensive logging
• Unified: Consistent patterns across all workflow templates
• Secured: Built-in input validation and security checks
• Traceable: Complete audit trail with workflow execution history

Enterprise Security Features:

• Input Validation: Automated security scanning of workflow inputs
• Access Control: Role-based access to workflow operations
• Audit Logging: Complete execution history with security events
• Data Encryption: Sensitive data protection in transit and at rest
