The Craft· Rzemiosło
Rules, commandments and anti-patterns for building apps with Claude — so your project is understandable, safe to change and trustworthy from day one.

Three ways into the doctrine
Not sure where to begin? First grasp the “why”, then walk through the start, and read up in plain terms along the way. It’s worth going through all of it — each piece saves you pain later.
What is The Craft?
It’s not a framework manual. It’s a set of rules for humans and AI building software together — distilled from real projects, framed so you can apply it right away.
- Principles, not recipes — Short, firm rules with the “why”. They tell you when to slow down (because a mistake is costly) and when to move fast (because it’s cheap).
- For you and for the AI — You point your AI assistant (e.g. Claude) to The Craft as a set of rules to follow. Fewer errors, fewer surprises, a coherent project.
- A living document — The Craft grows after every project that taught us something. You download the current version and drop it into your repo.
Choose your level
The same doctrine at three depths. Start where you are today — and go deeper once you find your footing.
Business
For you if you want to understand the rules and the risks without writing a single line of code.
Technical
For you if you want to know how it works and exactly what to ask a contractor or an AI.
Codex
For you if you want the full register: operational rules for the agent and the maker.
Just starting out and don’t code? Where to start
Get started in 3 steps
Download The Craft
Grab the pack and unzip it in your project root — it drops straight into docs/rules/. That’s your rule set to start with.
Point your AI to it
Tell your assistant (Claude Code) to follow the rules in /docs/rules/. Start with the Decalogue and the “Day 0” checklist.
Build and come back
Work by the rules: document, test every change, deploy deliberately. Come back to the chapters when you need a detail.
Doctrine chapters
Seventeen chapters at three levels — from the business “why” to technical mastery. Read online or download the whole thing.
Download and kick off your project
