# Enhanced Workflow Engine - Context-Aware Execution
## System Overview
The Enhanced Workflow Engine provides intelligent workflow execution with context management, parallel processing, validation gates, and adaptive routing based on project complexity.

## Workflow Execution Engine
### Main Execution Controller
```yaml
execution_controller:
initialization:
- validate_workflow_definition
- initialize_context_store
- setup_agent_pool
- configure_monitoring
execution_loop:
- determine_ready_steps
- allocate_agent_resources
- execute_parallel_groups
- validate_outputs
- update_context_store
- check_quality_gates
- plan_next_iteration
completion_criteria:
- all_steps_completed: true
- quality_gates_passed: true
- context_validation: "success"

```
## Integration with Existing Agent Prompts
### Context Injection Enhancement
Each existing agent prompt gets enhanced with:
```yaml
# Added to each agent prompt
##
### Structured Context Available:
{{#context_engine}}
**Previous Agent Outputs:**
{{#each completed_agents}}
- **{{name}}**: {{outputs.primary}} (Quality: {{quality_score}}/10)
{{#each outputs.structured_data}}
- {{key}}: {{value}}
{{/each}}
{{/each}}
**Project Metadata:**
- Complexity Score: {{project_metadata.complexity_score}}/10
- Workflow Type: {{project_metadata.workflow_type}}
- Quality Threshold: {{configuration.quality_threshold}}
**Global Context:**
- Budget Level: {{global_context.project_constraints.budget_level}}
- Timeline: {{global_context.project_constraints.timeline}}
- Team Size: {{global_context.project_constraints.team_size}}
{{/context_engine}}

After completing your work, provide this structured self-assessment:
**Quality Metrics:**
- Completeness Score (1-10): [Your assessment]
- Clarity Score (1-10): [Your assessment]
- Implementation Readiness (1-10): [Your assessment]
- Alignment with Previous Work (1-10): [Your assessment]
**Validation Checklist:**
- [ ] All required sections completed
- [ ] Addresses all input requirements
- [ ] Maintains consistency with previous agents
- [ ] Includes specific, actionable content
- [ ] No placeholder or vague language
**Context Validation:**
- [ ] Referenced all required previous outputs
- [ ] Maintained consistency with project constraints
- [ ] Aligned with complexity score and project type
```
This Enhanced Workflow Engine transforms our static workflow system into an intelligent, adaptive orchestrator that manages context, validates quality, and recovers from errors automatically.
