ddd-playbook skillA

ddd-playbook is agent-read markdown (skill) from salimramirez/agent-skills: Model a business domain with Domain-Driven Design — bounded contexts, ubiquitous language, aggregates and their invariants, value objects, domain events, and context mapping. Use when designing or refactoring a domain model, deciding aggregate boundaries, splitting a system into bounded contexts, running or interpreting an EventStorming session, or when business rules are leaking into controllers, services, or UI components — even if the user never says "DDD". It covers the modeling and the desi.

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 salimramirez/agent-skills/ddd-playbook@v2.0.1
Exact content
mdr add salimramirez/agent-skills/ddd-playbook@sha256:e2365b13e9422053

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.
