# 🔄 Multi-Agent Workflows

## End-to-End Parallel Task Orchestration

Version: 0.1.0 Status: Specification (VAPORA v1.0 - Workflows) Purpose: Workflows where 10+ agents work in parallel, coordinated automatically

## 🎯 Objetivo

Orquestar workflows donde múltiples agentes trabajan en paralelo en diferentes aspectos de una tarea, sin intervención manual:

    Feature Request
        ↓
    ProjectManager crea task
        ↓ (paralelo)
    Architect diseña ────────┐
    Developer implementa ────├─→ Reviewer revisa ──┐
    Tester escribe tests ────┤                     ├─→ DecisionMaker aprueba
    Documenter prepara docs ─┤                     ├─→ DevOps deploya
    Security audita ────────┘                      │

### Workflow Adjustments

    #![allow(unused)]
    fn main() {
    pub enum WorkflowAdjustment {
        // Add more agents if progress slow
        AddAgent { agent_role: AgentRole, count: u32 },

        // Parallelize steps that were serial
        Parallelize { step_ids: Vec<String> },

        // Skip optional steps to save time
        SkipOptionalSteps { step_ids: Vec<String> },

        // Escalate blocker to DecisionMaker
        EscalateBlocker { step_id: String },

        // Pause workflow for manual review
        Pause { reason: String },

        // Cancel workflow if infeasible
        Cancel { reason: String },
    }

    // Example: If timeline too tight, add agents
    if projected_timeline > planned_timeline {
        workflow.adjust(WorkflowAdjustment::AddAgent {
            agent_role: AgentRole::Developer,
            count: 2,
        }).await?;
    }
    }

## 🎯 Implementation Checklist

- Workflow YAML/TOML parser
- State machine executor (Created→Completed)
- Parallel task scheduler
- Dependency resolution (topological sort)
- Gate evaluation (all_passed, any_approved, etc.)
- Blocking & escalation logic
- Rollback on failure
- Real-time dashboard
- Audit trail (who did what, when, why)
- CLI: `vapora workflow run feature-auth.yaml`
- CLI: `vapora workflow status --id feature-auth`
- Monitoring & alerting

## 📊 Success Metrics

✅ 10+ agents coordinated without errors ✅ Parallel execution actual (not serial) ✅ Dependencies respected ✅ Approval gates enforce correctly ✅ Rollback works on failure ✅ Dashboard updates real-time ✅ Workflow completes in <5% over estimated time

Version: 0.1.0 Status: ✅ Specification Complete (VAPORA v1.0) Purpose: Multi-agent parallel workflow orchestration
