---

## 📋 STEP-BY-STEP APPROACH

### Phase A: Preparation (20 min)
1. Generate Gitea API token (repo + admin:repo_hook scopes)
2. Create test repository: `autonomous-build-test`
3. Configure webhook: `/webhook/openhands-autonomous-build`

### Phase B: Add New Nodes (90 min)
1. **Node 3:** Initialize Retry Counter (Code node)
2. **Node 7:** Decision - Build OK? (IF node)
3. **Node 8:** Update Gitea Success (HTTP node)
4. **Node 9:** Format Error for Retry (Code node)
5. **Node 10:** Check Retry Count (IF node)

### Phase C: Modify Existing Nodes (60 min)
1. **Node 2:** Extract Repo Info (add fields)
2. **Node 4:** OpenHands Build (enhance + preserve data)
3. **Node 6:** Check Build Results (add success check)
4. **Node 11:** Final Response (support both paths)

### Phase D: Test (90 min)
1. Success path test
2. Retry with fixable errors
3. Max retries (3 attempts)
4. Real project test

## 💾 KEY CODE PATTERNS

### 1. Data Preservation (Critical!)
```javascript
const sshOutput = $json;
const repoData = $node["Extract Repo Info"].json;

return {
  ...repoData,              // ← PRESERVE INPUT
  code: sshOutput.code,
  stdout: sshOutput.stdout,
  stderr: sshOutput.stderr
};
```

### 2. Retry Counter Initialization
```javascript
$workflow.staticData = $workflow.staticData || {};
$workflow.staticData.retry_count = ($workflow.staticData.retry_count || 0) + 1;
```

### 3. Error Feedback Loop
```javascript
if (retryCount > 0) {
  task += `

PREVIOUS BUILD FAILED:
${errorDetails}`;
}
```

### 4. Gitea Status Update
```javascript
POST https://git.oky.sh/api/v1/repos/{owner}/{repo}/statuses/{sha}
{
  "state": "success",
  "description": "✅ Build passed after 2 attempt(s)",
  "context": "openhands/autonomous-build"
}
```

---

## 📊 SUCCESS CRITERIA

### Must Have ✅
- [ ] End-to-end workflow completes (push → build → response)
- [ ] OpenHands executes autonomously
- [ ] Retry counter prevents infinite loops (max 3)
- [ ] Error feedback improves subsequent attempts
- [ ] Gitea commit status updates (success/failure)
- [ ] Works with real projects

### Validation Tests
1. **Test Success Path:** Valid code builds in 1 attempt
2. **Test Retry Logic:** Fixable errors resolve in 2-3 attempts
3. **Test Max Retries:** Persistent errors fail after 3 attempts
4. **Test Real Project:** Actual MVP project builds successfully

## 🧪 QUICK TEST COMMANDS

### Manual Workflow Trigger
```bash
curl -X POST https://n8n.oky.sh/webhook/openhands-autonomous-build \
  -H "Content-Type: application/json" \
  -d '{
    "repository": {"name": "test-project", "full_name": "gitadmin/test-project"},
    "ref": "refs/heads/main",
    "after": "abc123def456789012345678901234567890abcd"
  }'
```

### Create Test Repository
```bash
curl -X POST https://git.oky.sh/api/v1/user/repos \
  -H "X-Gitea-Token: {YOUR_TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{"name":"autonomous-build-test"}'
```

### Test SSH Connectivity
```bash
ssh -i /home/bam/.ssh/n8n_key bam@localhost \
  "sh /home/bam/openhands-sdk-wrapper-sh.sh 'Test connection'"
```

## 🚨 CRITICAL WARNINGS

### ⚠️ Data Loss Prevention
- SSH nodes **overwrite ALL data**
- Must use `$node["Node Name"].json` pattern
- Always preserve repo data: `...repoData`

### ⚠️ Retry Counter
- Must initialize: `$workflow.staticData = $workflow.staticData || {}`
- Increment: `$workflow.staticData.retry_count = ($workflow.staticData.retry_count || 0) + 1`
- Check: `if (retryCount >= 3) return fail;`

### ⚠️ Gitea Token
- Required for status updates
- Must have scopes: `repo` + `admin:repo_hook`
- Format: `gho_...` or `gsat_...`

### ⚠️ SSH Configuration
- Host: `localhost`
- User: `bam`
- Key: `/home/bam/.ssh/n8n_key`
- Timeout: `300000` (5 minutes)
