ddd-best-practices skillA

ddd-best-practices is agent-read markdown (skill) from okhp3/skillz: Domain-Driven Design guidance for modeling complex domains. Use when designing Bounded Contexts or Subdomains, discovering Aggregate boundaries from invariants and transactions, defining Aggregate Roots, designing Domain Events, typed domain failures, or repository contracts, choosing exception vs Result/Either/Option semantics, choosing Repository vs DAO/query service/gateway, splitting oversized Aggregates, coordinating cross-Aggregate consistency, applying Context Mapping patterns, implementi.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add okhp3/skillz/ddd-best-practices@v1.0.0
Exact content
mdr add okhp3/skillz/ddd-best-practices@sha256:e59838a5d904cc70

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
