The 10 Guiding Principles
of Vibe Coding

A New Era of Software Development

12 min read

Introduction

Over the last six months, I've experienced firsthand the amazing progress in AI models when it comes to coding. From programming hardware to building complex software applications, the potential is absolutely massive and transformative.

But let's be honest: this is not a mature way of working yet. There's still a lot to learn and a lot to build. The tools are evolving rapidly, best practices are emerging through trial and error, and we're all figuring this out together.

"Fully give in to the vibes, embrace exponentials, and forget that the code even exists." — Andrej Karpathy, February 2025

When Andrej Karpathy coined the term "vibe coding" in February 2025, he described a paradigm shift in how we create software. That philosophy captured something real—but applying it effectively requires more than just enthusiasm.

Key Takeaway

Vibe coding isn't about abandoning craftsmanship—it's about redirecting your energy from writing code to guiding its creation. These 10 principles help you do it effectively.

The 10 Principles

1
Embrace the Vibe, But Stay in the Driver's Seat

The original philosophy is about trust: letting AI handle the mechanical aspects of coding while you focus on the creative vision. Accept suggestions freely, iterate quickly, and don't obsess over understanding every line. But this isn't blind faith—you're the architect, the AI is the builder. Know when to go with the flow and when to pull back for review. For prototypes and weekend projects, "Accept All" can be your friend. For production code, selective acceptance becomes essential.

2
Speak Plainly, But Speak Precisely

Your prompts are your code now. The AI isn't a mind reader—it's a highly capable collaborator that needs clear direction. Talk to it like you're explaining a project to a skilled colleague: naturally, but with enough specificity to avoid ambiguity. Instead of "Make something cool," try "Build a minimal to-do list app with soft pastel colors, oversized buttons for mobile, and local storage persistence." The sharper your request, the closer the first draft lands to your vision.

3
Start Simple, Scale Gradually

The most common mistake? Asking the AI to build everything at once. Complex projects overwhelm even the best models. Break your vision into milestones you can test independently: get the basic structure rendering, add core functionality, refine the user experience, handle edge cases, then polish and deploy. Each step should be something you can run and verify before moving to the next.

4
Iterate Relentlessly, But in Small Loops

Vibe coding thrives on rapid iteration. Rather than crafting one perfect mega-prompt, engage in a conversation. Make a request, test the output, refine with feedback, and repeat. The AI learns your preferences through dialogue. Not all iterations are equal—recognize when changes have architectural impact and plan accordingly. Start fresh chats for new features to avoid bloating the AI's context window.

5
Test Early, Test Often

Just because AI wrote it doesn't mean it works. Run the code after every meaningful change. Testing isn't just validation—it's your primary feedback mechanism. When things break, this is where you step in: know where to find helpful information (error messages, console logs, stack traces), and understand what the AI is trying to achieve. This feedback loop is where real learning happens.

6
Define What NOT to Do—And Protect What Matters

Constraints are as valuable as instructions. Telling the AI what to avoid prevents it from going off-track or breaking things that already work. Explicitly protect critical data: business logic, formulas, core text, data structures, and integration points. For major changes like re-architecting, always run full regression testing—the AI doesn't remember why certain code exists.

7
Document Your Standards

If you're using specific frameworks, coding conventions, or design patterns, tell the AI upfront. Better yet, embed these preferences in system rules or project documentation. Include tech stack preferences, code organization patterns, naming conventions, and security requirements. The more context the AI has about your standards, the less time you spend correcting deviations.

8
Security is Still Your Responsibility

This is non-negotiable. AI-generated code can contain vulnerabilities, especially when you're not reviewing every line. Never commit secrets or API keys, review authentication logic manually, run security scans on generated code, and be especially cautious with code handling user input. The AI can help write secure code—but only if you explicitly ask for it and verify the results.

9
Use Vibe Coding to Learn, Not Just to Ship

The most sustainable approach combines vibe coding speed with continuous learning. After the AI generates code that works, take time to understand how it works. Ask the AI to explain files in simple terms, add comments, or identify design patterns. Understanding the architecture—even if you didn't write it line by line—makes you a better collaborator and debugger.

10
Know When to Go Manual

Vibe coding is a powerful tool, but it's not the only tool. Security-critical systems, performance-sensitive algorithms, and complex debugging sessions may require you to roll up your sleeves and engage directly with the code. The hybrid approach wins: use vibe coding for rapid prototyping and boilerplate, then apply traditional engineering rigor for critical components.

Handling Architectural Changes

Not all iterations are equal. You need enough technical understanding to recognize when a requested change will cascade through your entire codebase.

Signs of Architectural Impact

Data Layer

Data Models

Changes to database schemas, API contracts, or data structures

Infrastructure

Frameworks

Switching libraries, authentication systems, or core dependencies

Structure

Organization

Restructuring folders or altering component communication

When You Spot a Major Change

  1. Stop and plan. Don't let the AI execute it in one go
  2. Break it into phases with clear boundaries between each step
  3. Define test plans for each phase before proceeding
  4. Verify stability at each checkpoint before moving to the next
  5. Keep rollback points so you can retreat if things go wrong
Pro Tip

If you're unsure whether a change is architectural, ask the AI: "Will this change affect multiple files or core systems? What's the blast radius?" Build your intuition over time.

Protecting Critical Assets

You need to explicitly protect the core assets that define your application's integrity.

What to Protect

Business Logic

Calculation rules, workflow sequences, validation conditions

Formulas

Financial calculations, pricing algorithms, conversion rates

Core Text

Legal disclaimers, compliance statements, branded messaging

Integration Points

External service connections, authentication flows, API contracts

Example Protection Rules

"Do NOT modify any functions in the pricing-engine folder"

"The tax calculation formula must remain exactly as implemented"

"Keep all text in the legal-notices component unchanged"

"Preserve the existing API response structure"

The Bottom Line

Vibe coding represents a fundamental shift in how we create software. It's not about being lazy or abandoning craftsmanship. It's about recognizing that our highest value as developers comes from vision, architecture, and judgment—not from typing semicolons.

The principles above aren't restrictions on vibe coding's freedom. They're the guardrails that let you move faster with confidence.

As Karpathy himself noted, this approach started as "not too bad for throwaway weekend projects." Nine months later, it's powering startups and enterprise applications alike. The question isn't whether to adopt vibe coding—it's how to do it well.

Ready to Start?

The best developers in 2025 aren't replacing their skills with AI—they're amplifying them. Start small, iterate relentlessly, and remember: the future of development is collaborative, not automated.
