if you need tools it just means the code is sub-par

Grep is a tool. But if I grep foo, it can’t tell me the difference between a function called foo, a variable called foo, or any other types that may have a foo, or a comment with foo in it. Even vscode can do “show me all uses of foo” in a single click, and be perfectly correct,

It's not perfectly correct, and that actually what makes it dangerous.

That take is so comically nonsensical I question why you’d even contribute it.

I have no doubt you read and write code without any tools.
