Ddd Context Mapping

This one helps you map out integration patterns between bounded contexts in a DDD system. You walk through context pairs, pick relationship types like upstream/downstream or anti-corruption layer, then document translation rules and ownership. It pushes you to think about failure modes and versioning upfront, which is smart because that's where most integration pain lives. Really shines during migrations or when you're wiring up multiple services and need clarity on who owns what contract. Just don't expect it to design your actual API schemas or magically align your org chart. Best used before you start building integration code, not after things are already coupled.
