Building Your First AI Coding Assistant

Step 1: Choose a Framework

Consider:

  • Your preferred workflow (terminal, VS Code, web)
  • Required features (autonomy, Git integration, etc.)
  • LLM provider preference
  • Programming language support

Step 2: Set Up Environment

# Create a new project
mkdir my-ai-assistant
cd my-ai-assistant

# Initialize Git
git init

# Install dependencies
npm init -y
npm install openai dotenv

Step 3: Configure API Keys

# Create .env file
echo "OPENAI_API_KEY=your-api-key-here" > .env

# Add to .gitignore
echo ".env" >> .gitignore

Step 4: Build Basic Assistant

# assistant.py
import os
from openai import OpenAI
from dotenv import load_dotenv

load_dotenv()

client = OpenAI(api_key=os.getenv("OPENAI_API_KEY"))

def create_assistant():
    assistant = client.beta.assistants.create(
        name="My Coding Assistant",
        instructions="You are a helpful coding assistant. Help users write, debug, and understand code.",
        model="gpt-4-turbo",
        tools=[{"type": "code_interpreter"}]
    )
    return assistant

def chat_with_assistant(assistant, message):
    thread = client.beta.threads.create()
    client.beta.threads.messages.create(
        thread_id=thread.id,
        role="user",
        content=message
    )
    run = client.beta.threads.runs.create(
        thread_id=thread.id,
        assistant_id=assistant.id
    )
    return run

if __name__ == "__main__":
    assistant = create_assistant()
    print("Assistant created! ID:", assistant.id)

Step 5: Test and Iterate

# Run your assistant
python assistant.py

# Test with queries
# "Help me write a Python function"
# "Debug this code"
# "Explain how this works"

Advanced Features to Implement

        files.extend(Path(directory).rglob(f'*{ext}'))
    return files

codebase = index_codebase('./src')
print(f"Found {len(codebase)} files in codebase")

        self._trim_context()
    
    def _trim_context(self):
        # Keep context within token limit
        while len(self.context) > 10:
            self.context.pop(0)

3. Tool Execution

# Execute tools safely
import subprocess

def execute_tool(command):
    try:
        result = subprocess.run(
            command,
            shell=True,
            capture_output=True,
            text=True,
            timeout=30
        )
        return {
            "success": True,
            "output": result.stdout,
            "error": result.stderr
        }
    except subprocess.TimeoutExpired:
        return {
            "success": False,
            "error": "Command timed out"
        }

4. Code Analysis

# Analyze code for issues
import ast

def analyze_code(code):
    try:
        tree = ast.parse(code)
        issues = []
        
        # Check for common issues
        for node in ast.walk(tree):
            if isinstance(node, ast.FunctionDef):
                if len(node.args.args) > 5:
                    issues.append(f"Function {node.name} has too many parameters")
        
        return issues
    except SyntaxError:
        return ["Syntax error in code"]

Best Practices

1. Security

  • Never hardcode API keys
  • Use environment variables
  • Implement rate limiting
  • Validate user inputs
  • Sanitize code execution

2. Performance

  • Cache responses when possible
  • Use streaming for long responses
  • Implement lazy loading
  • Optimize context management
  • Use efficient data structures

3. User Experience

  • Provide clear error messages
  • Show progress indicators
  • Implement undo/redo
  • Save conversation history
  • Support keyboard shortcuts

4. Code Quality

  • Write tests for your assistant
  • Document your code
  • Follow best practices
  • Handle edge cases
  • Implement proper error handling
