📖 Chapter 9: The AI Workflow – Coding with a Robotic Sidekick

“You’re not just coding. You’re conducting a duet. And your partner is an autocomplete ghost with an encyclopedic memory and a flair for drama.”

🤝 Working with AI, Not for It

Using Cursor AI is like pair-programming with:

• A junior dev
• A senior dev
• And a caffeine-addled autocomplete engine

Cursor doesn’t just finish your code—it:

• Writes entire functions from a sentence
• Refactors your mess into elegance
• Answers your “what does this even do” questions
• Occasionally hallucinates, like a genius who skipped lunch

You need a workflow that’s both structured and flexible—like jazz in a helmet store.

🧠 Step 1: Write the Comment First (aka Prompt Engineering for Code)

Cursor loves clear instructions:

# Create a function that checks if a number is prime

Then try a more detailed version:

# Write a function that:
# - checks if a number is prime
# - returns True or False
# - handles edge cases
# - uses early exit for speed

You’re ordering code like a very technical waiter.

🧪 Cursor Prompt Practice

1. # Make a to-do list app
2. # Let the user add, remove, and list tasks
3. # Save the tasks in a JSON file
4. # Add error handling if the file doesn't exist

Cursor will follow your lead like a caffeinated golden retriever. 🐕

🧰 Step 2: Edit the AI's Output (Don't Just Trust It)

Cursor is good—but you are the final authority.

Always:

• Read it
• Test it
• Refactor it

Ask yourself:

• Is this readable?
• Is this efficient?
• Does this make sense to future me at 2am?

Your job: curate the raw output into art (or at least runnable code).

🧙‍♂️ Step 3: Use It Like a Dev Team

It’s like five interns, one genius, and Stack Overflow’s ghost in your editor.

💡 Strategy: Chat with Your Code

Treat Cursor like a conversation partner:

1. Comment what you want
2. Let it generate
3. Comment what’s wrong
4. Let it fix it
5. Repeat

# This function is too slow. Can you optimize it?

# I don't like the variable names. Make them friendlier.

You’re not just coding. You’re collaborating with a slightly manic assistant who never sleeps.

🎮 Mini Project: Refactor With AI

# Here's a messy function. Refactor it into clean, readable code.

Watch Cursor:

• Extract smaller functions
• Rename things
• Add docstrings like a nerdy poetry bot

Then try:

• “Add unit tests”
• “Explain this like I’m five”
• “Rewrite it in Shakespearean Python”

🛠️ Pro-Level Moves

• Use the sidebar chat to ask questions
• Highlight code → right-click → "Explain" or "Fix"
• Control verbosity by adjusting prompt detail
• Use Git to catch AI sneakiness

The AI is confident, not always correct.
Like a charismatic barista making up espresso science.

🧃 Workflow Recap Smoothie

• Comment before you code
• Edit everything AI gives you
• Ask follow-up prompts
• Use Cursor like a team member
• Mix structure with curiosity. That’s the vibe.

🎁 Challenge: Build Something Entirely with Comments

# A command-line calculator
# that handles +, -, *, /
# with input validation and history tracking

Then guide it further:

• “Add option to save result to file”
• “Make it pretty with ASCII art”
• “Add sarcastic responses if input is invalid”

You’re coding by vibes now. And that’s powerful.
