Advanced Techniques & Power User Tips

1. Prompt Engineering for Code

Master the Art of AI Prompts:

// Bad Prompt
// Make this better

// Good Prompt
// Refactor this function to:
// 1. Use async/await instead of callbacks
// 2. Add error handling with try-catch
// 3. Implement input validation
// 4. Add JSDoc documentation
// 5. Follow Airbnb style guide

Prompt Templates:

  • Function Creation: "Create a [language] function that [action] with [parameters], handles [edge cases], and returns [output format]"
  • Refactoring: "Refactor this code to use [pattern/approach], improve [metric], and maintain [requirement]"
  • Documentation: "Generate comprehensive documentation including description, parameters, return values, examples, and edge cases"

2. Multi-File Context

Leverage Cross-File Intelligence:

# In utils.py
"""Utility functions for data processing"""

# In main.py
# AI understands context from utils.py
# Comment: Use the data cleaning function from utils to process user input

Best Practices:

3. Test-Driven Development with AI

AI-Powered TDD Workflow:

# Step 1: Write test first
def test_user_authentication():
    """Test user authentication with valid credentials"""
    assert authenticate_user("[email protected]", "password123") == True

# Step 2: Let AI generate implementation
# Comment: Implement authenticate_user function that validates email format,
# checks password against database, and returns boolean result

4. Code Review Automation

Use AI for Code Reviews:

// Before committing:
// 1. Ask AI: "Review this code for security vulnerabilities"
// 2. Ask AI: "Check for performance issues"
// 3. Ask AI: "Suggest improvements for readability"
// 4. Ask AI: "Verify error handling completeness"

5. Documentation Generation

Auto-Generate Documentation:

# Select function, ask AI:
# "Generate NumPy-style docstring with parameters, returns, raises, and examples"

def calculate_fibonacci(n: int, cache: dict = None) -> int:
    """
    Calculate the nth Fibonacci number using dynamic programming.
    
    Parameters
    ----------
    n : int
        The position in Fibonacci sequence (0-indexed)
    cache : dict, optional
        Memoization cache for optimization
        
    Returns
    -------
    int
        The nth Fibonacci number
        
    Raises
    ------
    ValueError
        If n is negative
        
    Examples
    --------
    >>> calculate_fibonacci(5)
    5
    >>> calculate_fibonacci(10)
    55
    """

6. API Integration Templates

Quick API Implementations:

// Prompt: "Create Express.js REST API with:
// - GET /users (list all)
// - GET /users/:id (get one)
// - POST /users (create)
// - PUT /users/:id (update)
// - DELETE /users/:id (delete)
// Include error handling, input validation, and MongoDB integration"

7. Database Query Optimization

AI-Assisted Query Tuning:

-- Ask AI: "Optimize this query for performance"
-- Original:
SELECT * FROM users WHERE created_at > '2024-01-01';

-- AI suggests:
CREATE INDEX idx_users_created_at ON users(created_at);
SELECT user_id, email, name FROM users 
WHERE created_at > '2024-01-01' 
ORDER BY created_at DESC;

8. Design Pattern Implementation

Generate Common Patterns:

# Prompt: "Implement Singleton pattern in Python with thread safety,
# lazy initialization, and proper documentation"

# AI generates complete implementation with:
# - Thread locking
# - Instance checking
