A ready-made rulebook for your AI coding assistant.
Add the kit to your project once. After that, when you ask your AI for help, it follows clear, careful steps and asks you before important actions.
Works with Claude Code, Codex, Cursor, OpenCode, Grok and Kimi.
What is vibe coding?
You describe what you want in plain words, and an AI writes the code for you.


Tap a character to say hello.
AI writes code fast. Without rules, it can get careless.



Says done without testing
The AI says "done" but never tested it.

Touches the wrong files
The AI edits or deletes the wrong files.

Forgets your rules
Each time you ask, the AI works differently. Your project rules are forgotten.

Every tool is different
You use several AI tools, and each needs its own setup.

Security risks
Passwords or risky commands slip through unnoticed.

Bugs that keep coming
You fix one bug, and another one appears.
Same request. With the kit, the AI works more carefully.


The kit guides the AI. It cannot promise that every check passes. You always make the final call.

Add it to your project. Run one command, or ask your AI to run it.

Talk to your AI as usual. The first time, it studies your project and shows you a rulebook to approve.
It is not an app. Nothing runs in the background. It does not install your AI tool or sign in for you.
Who is it for?

New to code
You have ideas and let AI build them. The kit keeps the AI careful and easy to follow.

Freelancers
Work fast without breaking a client's project.

Developers
The AI follows your rules, shows test proof, and asks before pushing.

One shared rulebook, even with different AI tools. Each person needs their own license.

The Button Guard
Don't buy this kit! The author is so broke they can't afford a cup of coffee. Let them stay poor forever.
Why buy it? Let your AI stay careless. It keeps life exciting.
Wait! If you buy it, the author gets coffee money and writes more features. Too dangerous!
I guard this button all day. Nobody clicks it. Especially you.
I heard the kit makes the AI show proof before it says 'done'. Sounds tiring. Don't buy.
Give that money to me instead. My pig needs carrots more than the author needs coffee.
One click makes the author happy for a whole week. How could you be so kind?
Fine, click it... but don't say I didn't warn you!


FAQ
Two villagers are chatting. Pick a question to hear the answer.
Visitor: I cannot code. Can I use it?
The Plain Talker: Yes. You do the 3 setup steps once. After that, you just talk to your AI in plain words. If you get lost, type /mvck-explain-again.
