The problem is, even if I only enforce some rules locally, another developer has a different set of rules. So when we git commit, we ping-pong changes and fix each others stuff over and over again, bloating commits. We used editor config files + analyzer configs in the past (that gets checked into version control too), but there were still too much friction.

Where now, the compiler flags & strict analyzer settings forces claude to do the right things (we explicitly tell claude not try and bypass or lower the barrier). I think it only works because we don't spend 95% of our time in the IDE anymore like a couple of years back, so we as developers no longer feel that friction, as claude tries to satisfy the compiler instead. Its a massive mental load that is just gone, we haven't had any conversations in meeting about this kinda stuff anymore (remember in the past we would have flameouts in meetings or code reviews about linter settings...).
