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

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:

{
  "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:

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:

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
