[Part 1] A Non-Coder's Full Development Setup Revealed — Starting with Claude Code

Introduction — About This Series

A private tutor with zero programming experience has been developing and running a SaaS product called "Kagemusha System" — with the help of AI.

In this series, I'll be introducing my development tools one by one.

I'm laying it all out — what tools a complete beginner uses and how they get things done. In 2026, more and more people are building things alongside AI, and I hope this information proves useful to someone out there.

Part 1: Claude Code — Where It All Began

Naturally, this is the first tool to introduce. Claude Code.

As of March 2026, searching "AI coding" on Google returns an overwhelming number of options. GitHub Copilot, Cursor, ChatGPT, Gemini…

I chose Claude Code for one reason.

It can read and write files directly.

Just how revolutionary this is for someone with no coding experience — I covered that in Parts 2 and 3 of this series.

What Is Claude Code?

Claude Code is a CLI (command-line interface) based AI coding tool provided by Anthropic.

Unlike ChatGPT, where code appears in a chat window, Claude Code reads your local files directly and edits them in place. No copy-pasting. No file-targeting mistakes.

How to Install

As a prerequisite, you need Node.js installed (I'll cover Node.js in the next part).

npm install -g @anthropic-ai/claude-code

Just type this in your terminal. Installation takes about a minute.

How to Use — The Basics

The usage is surprisingly simple.

1. Open your terminal
2. Navigate to the folder you want to work in
3. Type claude

That's it — Claude Code launches. From there, just talk to it in plain language.

That's literally all there is to it. No need to open the file. No need to understand the code.

How to Use — Automated Execution Mode

There's another powerful way to use it: the claude -p option.

claude -p "Generate today's blog post"

This is "prompt mode" — it returns results in a single command with no back-and-forth conversation. I use this to auto-generate blog posts every day.

Combine it with Task Scheduler (Windows' built-in scheduling feature), and you can build a system that automatically generates and publishes blog posts every morning. Even as a complete beginner.

Pricing

Claude Code is included in the Max plan (monthly subscription). It's not pay-per-use API billing, so the monthly cost stays the same no matter how much you use it.

This is a huge benefit for solo developers. Zero anxiety about "what if I use too much and get a massive bill."

How I Use It

Here are some real examples of how I use Claude Code day to day.

• Building new features — Just say "Add [feature X]" and it's done
• Fixing bugs — Paste the error message and say "Fix this"
• Deploying — "Deploy this to Cloudflare Pages"
• Blog post generation — Daily automated publishing (including this very article)
• Research — "Look up the latest info on this technology"
• Email responses — "Draft a reply to this inquiry"

In other words, I do virtually all development-related work together with Claude Code.

Thoughts from a Non-Coder

To be honest, I still can't write code from scratch.

But I can put into words what I want to build. Claude Code is like a translator — it converts those words into code.

In 2026, development isn't about whether you can write code. It's about whether you can articulate what you want to build.

[Part 2] Node.js & npm — Setting Up Your JavaScript Runtime

You need Node.js just to run Claude Code. But what even is Node.js? What's npm? I'll explain it all from a beginner's perspective.
