Careful mode for changes you can't undo
Some changes are easy to reverse. Others aren't. Careful mode adds extra checkpoints before the risky ones so you don't accidentally break something permanent.
Editing a local file is low-risk. If you mess up, you can undo it in seconds. Publishing a website, sending an email, or changing a database is high-risk. If you mess up, the mistake is already out in the world. Careful mode is the habit of treating high-risk actions differently from low-risk ones.
Before any action that affects real users or can't be easily reversed: pause. State what you're about to do in plain words. Confirm it's the right thing. Do it. Then verify the result.
This sounds like common sense. But when you're moving fast and everything is going well, the temptation to skip the pause is strong. Careful mode makes the pause mandatory for the actions where skipping it is most dangerous.
Make a short list of your high-risk actions. Publishing to production. Sending emails to customers. Changing database records. Modifying user permissions. For each one, add a personal rule: 'Before I do this, I will read back what I'm about to do and confirm it's right.'
The overhead is a few extra seconds per action. The protection is against mistakes that take hours or days to fix.
Every time you touch production, customer data, or anything that goes out to real people. The two-second confirmation is the cheapest insurance in building products.
