Started writing a short doc before every task and my code reviews got quieter

Simple habit that changed a lot for me: before I touch code, I write a few sentences in the ticket about what I'm going to change and why. Takes ten minutes.

Two things happened. First, half the time I catch a bad approach before writing a line. Second, my reviewers stopped leaving "why did you do it this way?" comments because the answer's already there. My PRs merge faster now, and I'm not even writing better code, I'm just explaining it up front.
