Habits that protect your work, save your time, keep costs where you put them, and help you know what to trust. They came from real work: files changed unexpectedly, tasks started over from the beginning, confident answers that turned out to need checking, costs noticed too late. Each lesson is turned into something you can do before the problem reaches you.
These are not rules for writing perfect prompts. They are working habits for keeping control while AI helps you write, research, design, teach, sell and build.
Practical working habits for using AI. They help you protect your files, check the answers that matter, keep control of what things cost, recover when something goes wrong, and recognise where your own judgment is still the thing that decides.
They are not commandments, and they are not tricks for writing perfect prompts. Use a rule when its risk applies to what you are doing. Ignore it when it does not.
Find the few that match what you are doing today. A rule that works removes a worry and a decision. It should never add one more thing to remember.
