> Using the right tool

"Tooling" can be many things: the IDE, the language, the app design, the framework etc

Investing in the right tooling is the "outcome" though. I would argue the actual skill is to be able to recognize when the current tool is not the right one, and that there is possibly a better tool to get the job done better, easier, faster. A "junior" dev (regardless of "years of experience") is one that gets stuck in the suboptimal tooling
