# 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- ❌ Stay with SSH: Works but outdated, more complex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 |
