You mean other than knowing what you're doing? It's hard not to bring that up when it comes to vibe coding and the resulting contemporary ideas of what it means to be a "dev" or "coder".

If I had to name only one coding habit that distinguishes a great dev, I'd say it's in the ability to say no to the things that don't actually matter. Software isn't just about solving problems; it's about solving the right problems, which almost never means solving every problem, in spite of the greatest wet dreams of product managers and senior leadership. Jira is what you get when you believe that software is about solving everyone's problems.
