I have a technique I call incompetence-based-mutation-testing.
Start making some changes. Bork everything, comment out half the existing code to just make stuff compile. Run tests. Watch tests pass.
Stop refactoring, go have a stern word with the tests.

Llewellyn Falco is one of my mentors and an excellent engineer as well as technical coach. He just shared his experience coaching a team in modern tools including AI. It seems to me that it's a story about engineering and process more than it is about AI: llewellynfalco.blogspot.com/2025/11/from...

There is not a single reason to have shared state between tests. Ever. The fact that we are running hundreds of tests against a single app is honestly ridiculous and throws any hope of isolation out the window.

New Danish research on menopause has just been published. They talked to 153.400 from 45 to 59, and the results have surprised the researchers:
Only 3% reported no symptoms at all!
While menopause is not a disease, it has huge effect on health and quality of life.

Attaching a code-generating firehose to our development process that was largely trained on short-form code examples means we need to really stay on top of the bigger picture as it emerges one test and one refactoring at a time.

AI-assisted coding is like the blind men and the elephant. Everyone's experiencing it from different vantage points.
Makes it genuinely hard to know whose experience is worth learning from.

That's to say, teams that struggle with refactoring skills are also teams that most likely struggle with design skills, because tapping into a rich pool of domain and design insights generated as you refactor in small, safe steps is out of their reach.
