domain-model skillA

domain-model is agent-read markdown (skill) from stevepolitodesign/skills: Turn a described business process into a domain model..

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.

What the file says

# Domain model

The user describes how their business actually works. You come back with the concepts hiding in that description — and every one of them traces to something they said. An invented model is worse than none: it's fluent, confident, wrong, and in six months it's in the code under a name nobody in the business recognizes.

Five things come out, and nothing else:

| | |
| --- | --- |
| **Language** | The words the business uses, meaning what the business means. |
| **Flow** | The events, in order. Past tense — something became true. |
| **Rules** | Whenever X happens, we do Y. The branches and the exceptions. |
| **Aggregates** | Whatever protects a rule and emits those events. |
| **Contexts** | Where a word stops meaning one thing and starts meaning another. |

No entities-versus-value-objects, no repositories, no schema, no class diagram — those are implementation, and this is what implementation gets checked against. Don't read code either. The code already chose names, and the ones it chose are the loudest thing in the room; read them and they end up in the model, at which point the model can only tell you what the code already says.
