Cursor Productivity Hacks

1. Configure Global AI Rules

- Don't give high-level advice
- Respond with actual code, avoid chatter
- Be casual and treat me as an expert
- Don't mention that you're an AI

2. Cmd+K for Inline Code Generation

# Prompt: "Create a function for Fibonacci calculation"
def fibonacci(n):
    if n <= 1:
        return n
    return fibonacci(n-1) + fibonacci(n-2)

3. Agent Mode for Multi-File Changes

Agent Mode can make complex changes across multiple files by understanding the entire project context.
