# Executive Summary: OpenHands SDK GitHub Actions Analysis

**Date:** 2025-12-02
**Subject:** New approach evaluation for Phase 3
**Recommendation:** ADOPT hybrid approach (n8n + GitHub Actions + OpenHands SDK)
**Status:** Ready for implementation

---

## 📋 What Was Analyzed

**Discovered:** OpenHands SDK documentation reveals a new Python-based approach for GitHub Actions integration, different from our current SSH-based n8n workflow.

**Evaluated:**
1. **Current Approach (Phase 2 - Working):** n8n → SSH → OpenHands CLI wrapper
2. **New Approach (GitHub Actions):** GitHub Actions → Python SDK → OpenHands
3. **Hybrid Approach (Recommended):** n8n → GitHub Actions → OpenHands SDK

---

## 🎯 Recommendation: Hybrid Approach

**Architecture:**
```
Git Push → Gitea Webhook → n8n → GitHub Actions → OpenHands SDK → Results
```

**Why This Approach:**
- ✅ **Proven Foundation:** Uses working n8n infrastructure
- ✅ **Modern Stack:** Leverages OpenHands Python SDK (no SSH)
- ✅ **Simpler:** 11 n8n nodes → 5 nodes
- ✅ **Better Observability:** Structured logging + artifacts
- ✅ **Risk Mitigation:** Can rollback to SSH approach if needed
- ✅ **Future-Proof:** Positions for full GitHub Actions migration

**Rejected Alternatives:**
- ❌ Full GitHub Actions: Requires Gitea Actions support (unknown)
- ❌ Stay with SSH: Works but outdated, more complex

## 📊 Comparison Summary

| Aspect | Current (SSH) | Hybrid (GitHub Actions) | Improvement |
|--------|---------------|------------------------|-------------|
| **Nodes in n8n** | 11 | 5 | 55% reduction |
| **Code Complexity** | High (SSH wrapper) | Medium (HTTP + SDK) | Significant |
| **Error Handling** | Manual | Native + SDK | Much better |
| **Logging** | Basic stdout/stderr | Structured + artifacts | Major upgrade |
| **Retry Logic** | Custom n8n | GitHub Actions native | Simpler |
| **Setup Time** | Already done | 3-4 days | One-time cost |
| **Maintenance** | Complex (SSH, wrapper) | Simple (HTTP, SDK) | Easier |

- Add workflow and agent script files
- Configure API keys (OpenHands, Gitea, GitHub)
- Test GitHub Actions manually

### Day 2: n8n Integration (4 hours)
- Modify workflow (ID: j1MmXaRhDjvkRSLa)
- Replace SSH node with HTTP node
- Add GitHub Actions trigger
- Test end-to-end flow

### Day 3: Error Handling (3 hours)
- Test failure scenarios
- Verify retry logic (max 3)

## ⚠️ Risks & Mitigations

| Risk | Impact | Likelihood | Mitigation |
|------|--------|------------|------------|
| Gitea Actions compatibility | Medium | Low | Use GitHub.com for Actions, keep Gitea as source |
| API key management | Low | Low | Use GitHub secrets, document clearly |
| Learning curve | Low | Medium | Use provided templates, gradual migration |
| Timeline overrun | Medium | Low | Phased approach, keep SSH as fallback |

**Overall Risk:** LOW (hybrid approach provides safety net)
