mkdir -p ~/agent58k
cd ~/agent58k

# Create virtual environment
python3 -m venv venv
source venv/bin/activate

# Install dependencies
pip install -r requirements.txt

# Make sure Ollama is running
ollama serve

# Pull the model (if not already downloaded)
ollama pull zdolny/qwen3-coder58k-tools:latest
```

## Usage

### Start the Server

```bash
cd ~/agent58k
source venv/bin/activate
python server.py
```

The server will start on `http://localhost:8000`

### Configure Your IDE

#### For Continue.dev

Edit `~/.continue/config.json`:

```json
{
  "models": [
    {
      "title": "Qwen Agent",
      "provider": "openai",
      "model": "zdolny/qwen3-coder58k-tools:latest",
      "apiBase": "http://localhost:8000/v1",
      "apiKey": "not-needed"
    }
  ]
}
```

#### For Cursor

1. Go to Settings → Models
2. Add Custom Model
3. Set:
   - API Base: `http://localhost:8000/v1`
   - Model: `zdolny/qwen3-coder58k-tools:latest`
   - API Key: (leave blank or any value)

#### For Other OpenAI-Compatible IDEs

Use these settings:
- **Base URL**: `http://localhost:8000/v1`
- **Model**: `zdolny/qwen3-coder58k-tools:latest`
- **API Key**: (not required, use any value)

## Available Tools

The agent has access to these tools:

1. **FileReadTool** - Read file contents with line ranges
2. **FileWriteTool** - Create/overwrite files
3. **FileEditTool** - Precise string replacement in files
4. **TerminalTool** - Execute shell commands
5. **GrepSearchTool** - Search workspace with regex support
6. **ListDirectoryTool** - List directory contents
7. **PythonExecuteTool** - Execute Python code
8. **GetErrorsTool** - Check for syntax/lint errors

## Example Requests

### File Operations

```
Read the main.py file, lines 50-100
```

```
Create a new file at src/utils/helper.py with function to parse JSON
```

```
In config.py, replace the old database URL with postgresql://localhost/newdb
```

### Terminal & Git

```
Run git status and show me what files changed
```

```
Install the requests library using pip
```

```
Run the tests in the tests/ directory
```

### Code Search

```
Find all TODO comments in Python files
```

```
Search for the function "calculate_total" in the codebase
```

### Analysis

```
Check if there are any syntax errors in src/app.py
```

```
List all files in the project directory
```

## API Endpoints

- `GET /` - Server info and capabilities
- `GET /v1/models` - List available models
- `POST /v1/chat/completions` - Chat endpoint (OpenAI compatible)
- `GET /health` - Health check
- `GET /docs` - Interactive API documentation (Swagger UI)

## Configuration

Edit the `LLM_CFG` in `server.py` to customize:

```python
LLM_CFG = {
    "model": "zdolny/qwen3-coder58k-tools:latest",
    "model_server": "http://127.0.0.1:11434/v1",
    "api_key": "your-api-key-here",
}
```

## Troubleshooting

### Server won't start

- Check if port 8000 is available: `lsof -i :8000`
- Make sure virtual environment is activated
- Verify all dependencies are installed: `pip list`

### Ollama connection issues

- Ensure Ollama is running: `ollama serve`
- Test the API: `curl http://localhost:11434/api/tags`
- Check the model is pulled: `ollama list`

### IDE not connecting

- Verify server is running: `curl http://localhost:8000/health`
- Check IDE configuration matches the base URL
- Look at server logs for connection attempts

### Agent not using tools

- Check server logs for tool execution
- Make sure requests are clear and actionable
- Try being more explicit: "Use the file read tool to read config.py"

## Advanced Usage

### Custom Tools

Add your own tools by creating a new `BaseTool` subclass:

```python
class MyCustomTool(BaseTool):
    description = "What this tool does"
    parameters = [{
        'name': 'param1',
        'type': 'string',
        'description': 'Parameter description',
        'required': True
    }]
    
    def call(self, params: str, **kwargs) -> str:
        args = json.loads(params)
        # Your tool logic here
        return "Tool result"

# Add to TOOLS list
TOOLS.append(MyCustomTool())
```

### Workspace Context

The agent works best when you:
- Provide clear file paths
- Mention specific functions/classes
- Be explicit about what you want done
- Give context about your project structure

### Multi-step Workflows

The agent can handle complex workflows:

```
1. Read the config.py file
2. Search for all files that import it
3. Update those files to use the new config format
4. Run the tests to verify everything works
```

## Performance Tips

1. **Use line ranges** when reading large files
2. **Be specific** with search queries to reduce noise
3. **Use file patterns** to limit search scope
4. **Set timeouts** for long-running terminal commands

## Security Notes

- The agent can execute **ANY** shell command
- It can read/write **ANY** file the server user has access to
- **DO NOT** expose this server to the internet
- **Use only** on localhost/trusted networks
- Consider running in a container for isolation
