# Phase 3: Build Test Workflow - Documentation

**Status:** ✅ ACTIVE
**Workflow ID:** `EG9SCUWgbkdtr8Gm`
**Webhook URL:** `https://n8n.oky.sh/webhook/openhands-build-test`
**Created:** 2025-12-02
**Active:** Yes

---

## 🎯 Purpose

Autonomous build/test system that:
- ✅ Executes builds automatically
- ✅ Detects failures
- ✅ Provides feedback to OpenHands
- ✅ Retries with improved instructions
- ✅ Updates commit status in Gitea
- ✅ Prevents infinite loops with max retry limit (3)

---

## 🔄 Workflow Flow

### High-Level Process

```
[1] Git Push (Developer)
    ↓
[2] Filter OpenHands Commits (skip if message contains "openhands")
    ↓
[3] Prepare Build Task (initialize retry counter)
    ↓
[4] Execute OpenHands (run build/test)
    ↓
[5] Analyze Build Result (check success/failure)
    ↓
[6] Decision: Build Success?
    ├─ YES → [7] Update Gitea Success → [8] Respond
    └─ NO → [9] Check Retry Count
              ├─ < 3 → Back to [3] (retry with error feedback)
              └─ ≥ 3 → [8] Respond with failure
```

## 📊 Node Details

### 1. Gitea Webhook
- **Type:** Webhook Trigger
- **Path:** `openhands-build-test`
- **Method:** POST
- **Purpose:** Receives push events from Gitea

### 2. Filter OpenHands Commits
- **Type:** Code Node
- **Purpose:** Detects commits made by OpenHands and skips them to prevent infinite loop
- **Logic:**
  ```javascript
  if (commitMsg.toLowerCase().includes('openhands')) {
    return { skip: true, reason: 'OpenHands commit detected' };
  }
  ```

### 3. Should Skip?
- **Type:** IF Node
- **Condition:** `skip === true`
- **Branches:**
  - TRUE → Commit Skipped (exit workflow)
  - FALSE → Prepare Build Task (continue)

### 4. Prepare Build Task
- **Type:** Code Node
- **Purpose:**
  - Increments retry counter using `$getWorkflowStaticData('global')`
  - Checks if max retries (3) exceeded
  - Builds task message with error feedback (if retry)
- **Retry Logic:**
  ```javascript
  staticData.retry_count = (staticData.retry_count || 0) + 1;
  if (retryCount >= 3) {
    return { action: 'FAIL', status: 'FAILED' };
  }
  ```

### 5. Execute OpenHands
- **Type:** SSH Node
- **Command:**
  ```bash
  sh /home/bam/openhands-sdk-wrapper-sh.sh "<task>" "<workspace>"
  ```
- **Purpose:** Runs OpenHands SDK to build/test the project

### 6. Analyze Build Result
- **Type:** Code Node
- **Purpose:** Determines if build succeeded or failed
- **Success Indicators:**
  - Exit code = 0
  - Contains "passing", "✓", "PASS"
  - Contains "success" or "build complete"
- **Failure Indicators:**
  - Exit code ≠ 0
  - Contains "failing", "✗", "FAIL"
  - Contains "error" in stderr

### 7. Build Success?
- **Type:** IF Node
- **Condition:** `build_result.status === 'SUCCESS'`
- **Branches:**
  - TRUE → Handle Success
  - FALSE → Handle Failure

### 8. Handle Success
- **Type:** Code Node
- **Purpose:**
  - Formats success message
  - Resets retry counter to 0
  - Returns completion status
- **Output:**
  ```javascript
  {
    status: 'SUCCESS',
    action: 'COMPLETED',
    message: '✅ BUILD SUCCESSFUL',
    retry_count: X,
    build_result: {...}
  }
  ```

### 9. Update Gitea Success
- **Type:** SSH Node
- **Purpose:** Updates commit status in Gitea
- **API Call:**
  ```bash
  curl -X POST "https://git.oky.sh/api/v1/repos/{owner}/{repo}/statuses/{sha}" \
    -H "Authorization: token {GITEA_TOKEN}" \
    -H "Content-Type: application/json" \
    -d "{\"state\": \"success\", \"description\": \"Build successful after X attempt(s)\"}"
  ```

### 10. Handle Failure
- **Type:** Code Node
- **Purpose:**
  - Formats failure message with error details
  - Calculates remaining retry attempts
  - Determines if should retry or give up
- **Logic:**
  ```javascript
  const remaining = max_retries - retry_count;
  const willRetry = remaining > 0;
  return {
    action: willRetry ? 'RETRY' : 'GIVE_UP',
    will_retry: willRetry
  };
  ```

### 11. Get Token
- **Type:** SSH Node
- **Purpose:** Reads Gitea API token from `/home/bam/.gitea_api_token`

### 12. Commit Skipped
- **Type:** Code Node
- **Purpose:** Handles skipped OpenHands commits
- **Output:**
  ```javascript
  {
    status: 'SKIPPED',
    message: 'OpenHands commit - skipped to prevent loop'
  }
  ```

### 13. Respond
- **Type:** Respond to Webhook
- **Purpose:** Returns final response to webhook caller

---

## 🔁 Retry Loop Flow

### On Failure (retry_count < 3):
```
Handle Failure → Prepare Build Task → Execute OpenHands → [LOOP]
```

**Task Message on Retry:**
```
🔄 BUILD RETRY - Attempt 2/3

Previous build FAILED with errors:
[ERROR_DETAILS]

Please fix these issues and rebuild the project in /home/bam/claude/[repo]

Steps:
1. Analyze the errors above
2. Fix the code
3. Run tests (npm test or appropriate command)
4. If tests pass, commit with message: "OpenHands: Build successful"
```

### On Max Retries (retry_count >= 3):
```
Handle Failure → Respond with GIVE_UP status
```

---

## 🚀 How to Use

### Step 1: Developer Pushes Code
```bash
cd /path/to/repo
git add .
git commit -m "Add new feature"
git push origin main
```

### Step 2: Webhook Triggered
- Gitea sends POST to `https://n8n.oky.sh/webhook/openhands-build-test`
- Workflow starts processing

### Step 3: OpenHands Builds
- Executes in project directory
- Runs build commands (npm install, npm test, etc.)
- Commits fixes with message: "OpenHands: Build successful"

### Step 4: Loop Prevention
- If OpenHands commits changes, workflow skips it (no infinite loop)
- Only processes commits from developers

### Step 5: Status Updates
- **Success:** Gitea commit status = ✅ success
- **Failure:** After 3 attempts, status = ❌ failure

---

## 📝 Testing

### Manual Test
```bash
curl -X POST https://n8n.oky.sh/webhook/openhands-build-test \
  -H "Content-Type: application/json" \
  -d '{
    "repository": {
      "name": "phase3-test",
      "full_name": "gitadmin/phase3-test"
    },
    "ref": "refs/heads/main",
    "after": "abc123",
    "commits": [{"message": "Test commit"}]
  }'
```

### Real Repository Test
1. Make changes to `/home/bam/claude/phase3-test/`
2. Commit with message: "Test build"
3. Push to Gitea
4. Watch workflow execute
5. Check logs in `/home/bam/claude/phase3-test/openhands-task.log`
