This is your go-to when you need to move beyond "just make it work" to "make it maintainable at scale." It covers Clean Architecture, Hexagonal Architecture, and DDD with practical migration steps, not just theory. The skill shines when designing greenfield systems or refactoring monoliths into something your team can actually reason about. Worth noting: it explicitly recommends durable execution frameworks like DBOS for workflows that need crash recovery, which is refreshingly specific advice you don't see in most architecture guides. Skip it for small refactors or pure frontend work. The implementation playbook in resources should give you checklists and templates to actually apply this stuff.
