**🏆 WINNER: SDK Approach eliminates all previous blockers!**

---

## 🔬 **TECHNICAL BREAKTHROUGH**

### What We Proved Works:
```python
# ✅ SDK Import - No Docker needed!
from openhands.sdk import LLM, Agent, Conversation, Tool
from openhands.tools.file_editor import FileEditorTool

# ✅ LLM Configuration - Works!
llm = LLM(
    model="openai/MiniMax-M2",
    api_key="your-api-key",
    base_url="https://api.minimax.io/v1"
)

# ✅ Agent Creation - Works!
agent = Agent(
    llm=llm,
    tools=[Tool(name=FileEditorTool.name)]
)

# ✅ Conversation Start - Works!
conversation = Conversation(agent=agent, workspace="/home/bam")

# ✅ FileEditor Initialization - Works!
FileEditor initialized with cwd: /home/bam
```

### Evidence from Logs:
```
[11/30/25 23:47:38] INFO     FileEditor initialized with cwd: /home/bam
[11/30/25 23:47:38] INFO     Loaded 1 tools from spec: ['file_editor']
✅ LLM configured successfully!
✅ Agent created successfully!
✅ Conversation started successfully!
```

**NO Docker containers. NO network timeouts. NO TTY issues.**

---

## 🧪 **SDK TESTING RESULTS**

### ✅ Successfully Tested:
1. **SDK Installation** - Built from source successfully
2. **Python Import** - All modules import without errors
3. **LLM Configuration** - Agent accepts MiniMax configuration
4. **Tool Loading** - FileEditor tool initializes correctly
5. **Conversation Creation** - State management works
6. **Workspace Integration** - Local workspace setup successful
7. **Agent Execution Start** - Begins processing task

### ❌ Current Blocker:
- **MiniMax API Authentication** - Compatibility issue with LiteLLM
- **Error:** "Please carry the API secret key in the 'Authorization' field"
- **Analysis:** SDK architecture works, API configuration needs adjustment

---

## 🎯 **WHY SDK APPROACH IS SUPERIOR**

### 1. **Zero Docker Dependencies**
- Runs directly in Python
- No container networking issues
- No runtime connectivity problems
- No TTY requirements

### 2. **Perfect for n8n Integration**
- Simple Python script execution
- Can be called via n8n SSH node
- Direct file system access
- No external dependencies

### 3. **Native Python Architecture**
```python
# Perfect for n8n workflow
import subprocess
result = subprocess.run([
    'python', '/home/bam/openhands-sdk-wrapper.py',
    'Create a test file'
], capture_output=True, text=True)
```

### 4. **Built-in Tool System**
- FileEditorTool - File operations
- TerminalTool - Command execution
- TaskTrackerTool - Progress tracking
- Custom tools support

---

## 🛠️ **IMPLEMENTATION FOR n8n**

### n8n Workflow Integration:
```json
{
  "nodes": [
    {
      "name": "Webhook Trigger",
      "type": "n8n-nodes-base.webhook"
    },
    {
      "name": "Execute OpenHands SDK",
      "type": "n8n-nodes-base.ssh",
      "parameters": {
        "command": "cd /tmp/software-agent-sdk && source .venv/bin/activate && source /home/bam/openhands/.env && python /home/bam/sdk-wrapper.py \"{{ $json.task }}\""
      }
    },
    {
      "name": "Verify Results",
      "type": "n8n-nodes-base.ssh",
      "parameters": {
        "command": "ls -la /home/bam/*.txt"
      }
    }
  ]
}
```

### SDK Wrapper Script:
```python
#!/usr/bin/env python3
import sys
sys.path.insert(0, '/tmp/software-agent-sdk')

from openhands.sdk import LLM, Agent, Conversation, Tool
from openhands.tools.file_editor import FileEditorTool
import os

def run_openhands_task(task):
    llm = LLM(
        model="openai/MiniMax-M2",
        api_key=os.getenv("MINIMAX_API_KEY"),
        base_url="https://api.minimax.io/v1"
    )

    agent = Agent(llm=llm, tools=[Tool(name=FileEditorTool.name)])
    conversation = Conversation(agent=agent, workspace="/home/bam")
    conversation.send_message(task)
    conversation.run()

if __name__ == "__main__":
    task = sys.argv[1]
    run_openhands_task(task)
```

---

## 🔧 **FIXING THE API ISSUE**

### Root Cause Analysis:
The SDK uses **LiteLLM** as the underlying LLM client. MiniMax API may require different authentication headers.

### Solution Options:

**Option 1: Use MiniMax-Compliant Model**
```python
# Try different model names
llm = LLM(
    model="minimax/abab6.5s-chat",  # Native MiniMax model
    api_key=os.getenv("MINIMAX_API_KEY"),
    base_url="https://api.minimax.io/v1"
)
```

**Option 2: Use OpenAI-Compatible Endpoint**
```python
llm = LLM(
    model="gpt-4o",
    api_key=os.getenv("OPENAI_API_KEY"),  # Use OpenAI key
    base_url="https://api.minimax.io/v1/text/chatcompletion_v2"
)
```

**Option 3: Direct API Integration**
```python
# Bypass LiteLLM, use direct requests
import requests

response = requests.post(
    "https://api.minimax.io/v1/text/chatcompletion_v2",
    headers={"Authorization": f"Bearer {api_key}"},
    json={
        "model": "abab6.5s-chat",
        "messages": [...]
    }
)
```
