概要
This skill equips Claude with the architectural blueprints and implementation patterns required to build high-scale, event-driven systems. It guides the transition from traditional state-based storage to event sourcing, providing deep insights into aggregate rehydration, stream organization, and the development of eventually consistent read models. By leveraging established industry literature and documentation-first approaches, it helps developers manage complex domain logic, maintain perfect audit trails, and implement sophisticated versioning strategies like upcasting to ensure long-term system evolution.
