This fresh, exciting approach to software development has really caught my attention.

I’ve been experimenting with it with Cursors and OpenAI for private projects, and I can’t help but reflect on what kind of opportunities can offer but at the same time what kind of concerns rise.

So, grab a cup of coffee, and let’s chat about this!

What is Vibe Coding?

I stumbled upon this concept following some trends on Youtube and Twitch. Some developers, instead of following a strict plan, just went with the flow, bouncing ideas off each other and letting creativity take the lead.

As I see it, Vibe Coding is the practice of developing software with a focus on intuition, real-time collaboration with AI, and a highly iterative approach.

It’s about leveraging the dynamic capabilities of modern tools to accelerate development, but it also raises questions about maintainability and long-term code quality. It’s the difference between following a detailed map and navigating by feel, with a sophisticated GPS system as your guide.

I’m experimenting using AI tools like GitHub Copilot, Cursor and OpenAI and it has been a game-changer.

They help me brainstorm and generate code snippets in real-time, which really cuts down on the mental load. It’s like having a creative partner who’s always ready to jump in!

Core Principles of Vibe Coding

We’ve all experienced those moments where coding feels less like a chore and more like a creative endeavor. Time seems to melt away, and lines of code materialize as if by magic. This “flow state,” as it’s often called, is the essence of vibe coding. It’s about cultivating an environment where intuition and creativity can flourish. This intuitive approach not only fosters a deeper connection with the code but also significantly enhances the developer’s overall experience. By streamlining workflows and minimizing friction, vibe coding allows developers to focus on the creative aspects of their work, leading to increased satisfaction and a more enjoyable development process. Imagine a development environment where the code feels less like a rigid set of instructions and more like a fluid expression of your ideas. This is the promise of vibe coding.

I see 3 core principles:

1. Code as a Dynamic Entity: I’ve learned to see my code as something that can change and grow, rather than a fixed set of rules.
2. AI as a Collaborative Tool: These AI assistants don’t replace my creativity; they enhance it. It’s a partnership that I’ve come to rely on.
3. Continuous Innovation: Forget linear planning! I’ve embraced prototyping and iteration, which feels much more natural and exciting.

Oversight needed

Real example: I have generated a function that performs a transformation, but Copilot overlooked crucial validation steps.

In this case, the transformData function simply multiplies the input data by 2 and adds 10, without checking if the input is a valid number or handling potential edge cases like NaN, Infinity, or extremely large numbers.

// Example of using AI to generate a data transformation function in TypeScript
function transformData(data: number): number {
  // AI suggests a series of transformations based on context
  const transformedData = data * 2 + 10;
  return transformedData;
}

It’s working, tests are passing, but it isn’t something I would have done or expected from senior developers.

Without proper oversight, this simple function could introduce critical errors.

Imagine if the input data contains NaN or Infinity; the function would produce unexpected results, potentially propagating these invalid values through the system. If the input data is an extremely large number, the result could exceed the maximum safe integer value in JavaScript, leading to loss of precision or unexpected behavior.

This highlights the need for clear guidelines and robust review processes.

We need to ensure that the speed of development doesn’t come at the cost of stability and reliability.

To illustrate the importance of human oversight, let’s consider a corrected version of the transformData function:

function transformData(data: number): number {
  if (typeof data !== 'number' || isNaN(data) || !isFinite(data)) {
    console.error('Invalid input data:', data);
    return NaN; // Return NaN for invalid input
  }

  const transformedData = data * 2 + 10;

  if (!Number.isSafeInteger(transformedData)) {
    console.warn(
      'Transformed data exceeds safe integer range:',
      transformedData
    );
  }

  return transformedData;
}

In this corrected version, we’ve added input validation to check if the input is a valid number and handle cases like NaN and Infinity. We’ve also included a check to ensure that the transformed data stays within the safe integer range. This demonstrates how human intervention can enhance the robustness and reliability of AI-generated code.

Well, the enhanced version could have been also written using the AI, but to reach this kind of results, the instructions must be extremely clear and detailed.

What I want to highlight, is that crafting this corrected example requires a developer with considerable experience and knowledge.

AI tools needs to be guided from someone who can identify potential pitfalls, has a solid understanding of data types, edge cases, and best practices.

Experienced developers usually leverage their ‘gut feeling’ to make informed decisions. This isn’t about abandoning logic or best practices; rather, it’s about recognizing the value of experience and pattern recognition.

Developers often develop a sense for what ‘feels right’ in code, allowing them to identify potential issues and craft elegant solutions more efficiently.

Opportunities and Responsibilities

Vibe coding offers the potential for faster development cycles, increased developer engagement, and a more creative approach to problem-solving.

However, these opportunities must be balanced against the risks of polluting the codebase, introducing technical debt, and eroding fundamental coding skills.

IT Leaders need to observe, analyze, and strategically integrate these new approaches, but they also need to ensure that innovation doesn’t come at the expense of maintainability and reliability.

Setting the Guardrails

Few key concepts create an environment that can quickly adopt new tools keeping the risk low:

1. Establish Clear Guidelines: Define coding standards, review processes, and architectural constraints to ensure code quality and consistency. Implement regular code reviews, enforce coding standards through automated linters and static analysis tools, and conduct regular architectural reviews to prevent the introduction of technical debt.
2. Foster Critical Thinking: Encourage developers to understand the code they produce, even when using AI. Implement regular training sessions to reinforce coding fundamentals, critical thinking skills, and architectural principles. Encourage developers to experiment with new tools and techniques, but also to critically evaluate their impact.
3. Strategic Integration: Identify which aspects of vibe coding are beneficial and integrate them in a controlled manner. Use pilot projects to test new approaches, gather data on their effectiveness, and refine processes based on feedback. Implement a phased rollout of new tools and techniques, and monitor their impact closely.

Alternative Approaches and Blending Strategies

1. Hybrid Methodologies: Combine the flexibility of vibe coding with the structure of Agile or other methodologies. Use Agile sprints to provide structure, while allowing for flexibility within each sprint. Implement a “sprint zero” to define architectural constraints and coding standards, and use sprint retrospectives to refine processes.
2. Continuous Improvement: Implement a culture of continuous improvement, where developers are encouraged to experiment, learn from their experiences, and share their knowledge. Use retrospectives to identify areas for improvement, conduct regular code katas to reinforce coding skills, and organize internal tech talks to share knowledge and best practices.

Conclusion

Vibe coding represents an evolving trend in software development. As Engineering Managers, it’s our responsibility to observe, analyze, and strategically integrate these new approaches.
