I am literally right now undoing a bunch of slop code because of this. We had a gateway/bff pattern (basically, bff when we only have a single frontend atm but plan on developing others in the future), and this service's whole job was querying CRUD APIs on other services, marshalling/trimming their responses to just what the frontend needs and serving it. One of our other devs has been Claudehopping around, too focused on shitting out new features as quickly as possible and not paying attention to how it's done, and now several of the calls to the gateway have it accessing the DB directly via repository classes while others are calling existing services. That's fine except I have to change the way we filter things now. Had he and Claude actually stuck with the pattern it would be a single change in one of the services behind the gateway but now I need a bucket and a mop for this WET ass programming because I have to change it at the gateway level AND at the service level.
