Where to start
You don’t need to know how to code to build an app with AI safely — you just need to learn a few rules and the first move.
- 1
What it is in one sentence
The Craft is a set of proven rules for building apps with Claude — an AI assistant that can write code for you. It isn’t a programming manual. It’s more a list of habits that keep a project run with AI from turning into chaos. You read it to know what to ask, what to watch for and when to say “stop”, even if you never write a single line of code yourself.

3 things that save a project
Three rules make the biggest difference. First: verify, don’t take it on faith — “probably works” isn’t the same as “I checked and it works”, so ask for proof that something actually worked. Second: always keep a copy you can return to — before the AI changes any important data, a point of return must exist. Third: production and user data are sacred — what real customers see changes only deliberately, on your explicit “deploy”, never “by the way”.

How to talk to the AI so it helps you
Speak plainly about what you want and why — the AI can’t read your mind, but it understands a goal well. Ask for a plan before action (“show me what you intend to do before you do it”) and for proof afterwards (“show me it works”). Most important: point the AI to The Craft as rules to follow — then it keeps those three rules for you, and you don’t have to remember each one.

Your first safe move
Start with one small step. Download the free Craft pack — no sign-up, no personal details. Unzip it into the /docs/rules/ folder in your project (just the place where you keep the rules) and tell your AI assistant to follow them. Then walk through “Day 0” with it — a short checklist of questions and settings for the start. That’s it. That’s enough to get going safely.

When you find your footing — go higher
The Craft comes at three levels of the same knowledge. You’re on Level 1 — Business, the “why” without code. When you want to understand how things work in practice and exactly what to ask a contractor or an AI, move up to Level 2 — Technical. And if you catch the bug, Level 3 awaits — the full Craft: 17 chapters and the Decalogue, the 10 commandments in full. Go higher when you feel ready, not before.
