How I Use AI Coding Assistants Without Turning My Brain to Mush

Here's the thing: AI coding tools are incredible. They're also kinda scary if you use them wrong.

I've been coding with AI assistants for months now, and I've learned the hard way that there's a right way and a wrong way to do this. The wrong way? Copy-paste everything, never think, wake up one day and realize you can't write a for-loop without prompting ChatGPT.

Here's what actually works.

The 30-Second Rule

Before I ask AI for help, I give myself 30 seconds to think about the problem. That's it. Just 30 seconds.

Why? Because most of the time, I already know the answer. My brain is just being lazy. Those 30 seconds force me to actually engage with the problem instead of outsourcing my thinking immediately.

Example: Need to reverse a string in Python? You probably know this. Take 30 seconds. Oh right, string[::-1]. Done.

The AI is there for when you're genuinely stuck, not when you're being lazy.

Use AI for Boilerplate, Not Logic

Here's my rule: AI writes the boring stuff, I write the interesting stuff.

Setting up Express routes? Sure, let AI generate that. The actual business logic that makes my app unique? That's mine.

What I let AI do:

• Config files (tsconfig, webpack, whatever)
• Basic CRUD operations
• Test boilerplate
• Type definitions

What I do myself:

• Core algorithms
• Business logic
• Anything that requires understanding my specific domain
• Bug fixes (more on this below)

The Debug-It-Yourself Rule

This one's non-negotiable: when something breaks, I debug it myself first.

AI is terrible at debugging because it doesn't see your full context. It'll suggest random fixes that might work but don't actually solve the root problem.

More importantly: debugging is how you learn. Every bug is a lesson. Skip that and you're just collecting code you don't understand.

My process:

1. Read the error message (shocking, I know)
2. Check the obvious stuff (typos, wrong variable names)
3. Console.log / debugger my way through it
4. Only then, if I'm truly stuck, explain the problem to AI

Usually by step 3, I've found it.

Ask "Why" Even When You Get the Answer

AI gives you code. Cool. Now ask it to explain what it just wrote.

Then read that explanation. Actually read it. If something doesn't make sense, ask follow-up questions.

Bad: copies code "Thanks!"

Good: "Why did you use Promise.all here instead of Promise.allSettled?"

Treat AI like a senior dev who's explaining code to you. You wouldn't just copy their code without understanding it, right? Right?

Keep a "Learned Today" Note

Every time AI teaches me something genuinely new, I write it down. Just a quick note in Obsidian or whatever.

Examples from my notes:

• "Optional chaining works in object destructuring"
• "Array.at(-1) is cleaner than array[array.length-1]"
• "CSS has container queries now"

Writing it down makes it stick. Plus, I review these notes every month. Stuff that used to be "AI knowledge" becomes my knowledge.

The Rewrite Test

Once a week, I pick something AI helped me build and rewrite it from scratch without AI.

Can you do it? If yes, congrats, you learned something. If no, you just borrowed code you don't understand.

This is uncomfortable but necessary. It's like checking if you can actually speak Spanish or if you just know how to use Google Translate.

Real Talk: The Balance

Look, I'm not saying never use AI. I use it constantly. It's saved me hundreds of hours.

But here's the question: are you using AI to augment your skills or replace them?

The difference is huge:

• Augment: "I know how to do this, but AI can do it faster"
• Replace: "I have no idea how this works, but AI gave me code that runs"

One makes you a better developer. The other makes you dependent.

What This Looks Like In Practice

Yesterday I built a feature that parses CSV files and generates reports. Here's how I used AI:

• AI generated: The CSV parsing boilerplate (30 seconds vs 5 minutes writing it myself)
• I wrote: The actual report logic, validation rules, error handling
• AI helped: Suggested edge cases I hadn't considered
• I debugged: When it broke (because of course it broke)

Total time: ~2 hours. Without AI? Maybe 3 hours. With AI but no thinking? Either 30 minutes of copying code I don't understand, or infinite time debugging mysterious issues.

The Bottom Line

AI coding assistants are tools, not shortcuts. Use them like you'd use Stack Overflow: helpful for learning, dangerous if you just copy-paste blindly.

Stay sharp. Keep thinking. Let AI handle the boring stuff so you can focus on the interesting problems.

And for the love of all that is holy, please debug your own code.
