How We Built a Code Quality Pipeline That Roasts Bad PRs Before Humans Have To

It's more of a group activity that happens gradually, like a potluck where everyone brings potato salad. When our team was small — two or three devs who reviewed every line — code quality maintained itself through osmosis. We all knew the patterns. We all agreed on formatting. Nobody wrote an 800-line component because someone would notice and gently question their life choices. Then the team grew. More features, more devs, more PRs flying in simultaneously. And the cracks started showing: Components quietly ballooning past 700 lines — because "I'll refactor it later" (narrator: they did not refactor it later) Formatting roulette: tabs here, spaces there, trailing commas in this file but not that one Duplicate i18n messages across different feature modules — the same English string defined in three different messages.js files with three different IDs, leading to translation mismatches and
