Claude Code and Vibe Coding: A Complete Guide to Writing Code with AI from Scratch

Introduction: Don't Let Programming Barriers Block Your Creativity

Have you ever had this experience — a brilliant idea flashes through your mind, maybe a small game, a useful mini-app, or an application that solves a real-life pain point — but when you open a programming syntax book and face walls of technical jargon, your enthusiasm instantly evaporates?

This used to be the biggest bottleneck for most people without a technical background. However, in 2025, a completely new development approach is fundamentally changing this landscape — even without any programming experience, you can start your code creation journey with AI programming tools.

Why Do Developers Prefer the Claude Model for Writing Code?

Many people outside the tech world may have only heard of ChatGPT, but within developer and programmer circles, the Claude model is the widely used AI code generation tool. This isn't baseless hype — it's backed by real capability differences.

Claude is a large language model series developed by Anthropic. Anthropic was co-founded in 2021 by former OpenAI Research VP Dario Amodei and his sister Daniela Amodei, with a core mission focused on AI safety research. Claude's advantages in code generation partly stem from its unique training method — Constitutional AI — which makes the model more inclined to follow clear logical rules when generating content, rather than simply pursuing output that "looks correct." This characteristic is particularly crucial in code generation scenarios — code can't just "look like code"; it must be logically rigorous to actually run.

Claude's core advantages in AI programming are reflected in three areas:

• Excellent logical comprehension: It can understand requirements expressed in plain language, like a programmer who truly understands the technology
• High-quality code generation: The output code is well-formatted and clearly structured, not the kind of redundant, bloated "garbage code"
• Detailed and readable comments: If needed, it will add thorough comments to every key code section, helping beginners understand the underlying logic

In short, Claude is currently one of the industry's leading code generation models — it doesn't just "translate" your requirements; it "understands" your intent.

From Web Chat to Terminal Resident: The Evolution of Claude Code

The Old Workflow: The Inefficient Era of Copy-Paste

The previous way of using Claude to write code was quite primitive — type your requirements into a web chat box, let the AI generate code, then manually copy and paste the code into your IDE (Integrated Development Environment). An IDE is professional software that programmers use to write code, such as VS Code or PyCharm, integrating features like code editing, debugging, and version control. This constant switching back and forth was not only tedious but error-prone, especially when projects involved multiple files — it was an absolute nightmare.

The Innovation: An AI Programmer "Living" Directly on Your Computer

Claude's team did something truly meaningful — they released the Claude Code command-line tool. A command-line tool (CLI, Command Line Interface) is a way to interact directly with a computer through text commands. Unlike the graphical interfaces we use daily, it's closer to the computer's underlying operating system and can directly access the file system, execute scripts, and manage code versions. Claude Code takes exactly this form, residing directly in your computer's terminal, rather than existing as an isolated web application.

Its workflow is very intuitive:

1. Authorization mechanism: When Claude Code needs to perform an operation, it first asks for your consent — for example, "I want to execute this line of code, do you accept?"
2. Confirmation to execute: You click accept, essentially granting it execution permission
3. Automated operations: Once authorized, it can modify files, copy and delete files, commit code, and more

This means you no longer need to switch between a browser and your editor — AI works directly in your development environment. The improvement in programming efficiency is a quantum leap.

Vibe Coding: A New Programming Philosophy Using Natural Language

The Origin of Vibe Coding

Precisely because of powerful underlying tools like Claude Code, a new term was born in developer circles — Vibe Coding, which can be understood as "intuition-driven programming" or "vibes-based programming."

This concept was proposed by Andrej Karpathy — former head of Tesla's Autopilot AI team and OpenAI co-founder, a figure of enormous influence in the AI field. Karpathy is a top scholar in deep learning who studied under Fei-Fei Li at Stanford for his PhD, focusing on the intersection of computer vision and natural language processing. The autonomous driving perception system he led at Tesla, along with the deep learning tutorials he published on YouTube, have had a profound impact on the global developer community. His proposal of the Vibe Coding concept was essentially a naming and definition of the "human-AI collaborative programming" trend, reflecting his deep insight into the future direction of AI-assisted development.

Core Philosophy: From "Worker" to "Boss"

It might sound abstract, but the essence of Vibe Coding is actually very simple:

You're no longer the "worker" writing code — you're the "creator" directing it.

In traditional programming, you need to personally type every line of code and handle every bug. In Vibe Coding mode, you're more like a boss — you're responsible for proposing requirements and describing the desired outcome in natural language, while AI handles the implementation.

This shift didn't emerge from nowhere. The evolution of tools in software development has continuously lowered the barrier to creation: from early machine code, to high-level programming languages, to visual low-code platforms (like Bubble and Webflow) — each evolution has enabled more people to participate in software creation. Vibe Coding represents the latest point on this evolutionary path — natural language becomes the programming interface. GitHub's 2023 survey data showed that developers using AI programming assistants achieved an average 55% increase in code commit speed, confirming AI-assisted programming's substantial impact on productivity.

Of course, AI isn't free. You need to purchase tokens to "pay" for its work. A token is the basic unit of text processing for large language models — think of it as a fragment of a word or phrase. For example, "programming" might be split into one or more tokens. The model consumes tokens every time it generates or reads content, so the number of tokens directly determines the scale of tasks AI can handle. When Claude Code processes large projects, it needs to "read" the entire codebase's context, which consumes a significant number of tokens. The more tokens you purchase, the more work AI can complete for you.

But compared to hiring human programmers, AI programming assistants have one enormous advantage — they can work 24/7 without ever getting tired. As long as you have sufficient tokens, they'll continue producing high-quality code for you.

Who Is Vibe Coding For?

Vibe Coding isn't meant to replace professional programmers — rather, it dramatically lowers the barrier to programming creation. It enables people with creative ideas but lacking programming skills to turn their visions into reality. The following groups are especially well-suited to give it a try:

• Entrepreneurs: Rapidly validate product prototypes without waiting for a development team's schedule
• Designers: Directly transform design mockups into runnable frontend code
• Product managers: Build interactive demos yourself, instead of just drawing wireframes
• Students and programming enthusiasts: Start a zero-to-one programming learning journey at minimal cost

Final Thoughts: AI Programming Makes Tech Equity a Reality

From Claude's code comprehension capabilities, to Claude Code's terminal integration, to the rise of the Vibe Coding philosophy, we are witnessing a paradigm shift in the programming world.

Programming is evolving from a "hard skill" into a "means of expression." Just as you don't need to be a professional photographer to take great photos with your phone, in the future you won't need to master programming languages to create valuable software products.

Of course, this doesn't mean professional programming knowledge becomes worthless. Quite the opposite — people who understand code logic will be far more effective when using these AI programming tools. But at the very least, creativity is no longer constrained by technical barriers — and that in itself is something worth looking forward to.

For those looking to get started, I recommend beginning by installing Claude Code and using it to complete a simple utility project — experience firsthand what it feels like to "write code with natural language."
