I'm not the other commenter, but this is part of my job. I'm often called in to deal with issues that have been created by bad developers, offshore developers, contractors or consultants who've helicoptered in and out, and now AI.
The basic requirements are the same in all these cases: identify the problem, recommend and/or implement fixes, and recommend process improvements.
Sometimes those improvements involve negative effects for the people perpetuating these issues.
It may not be wise to assume you can abdicate all responsibility for your work if you're somewhere that does, in the end, care about results.
