Models a business in its own language. Use when the domain has real business rules to capture.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# The Domain-Driven Design Paradigm

Design for the future, build for now.

DDD is modeling a business in the business's own language. The goal is not
to avoid structure. It is to avoid structure you cannot back out of, and to
defer structure you do not yet need.

## What DDD Is

Ubiquitous language, bounded contexts, and a model built by talking to the
people who do the work. The measure of a domain model is whether a person
in the business would recognize their own job in it.

## What DDD Is Not

Clean Architecture. Mandatory layering. A mapper between every tier. A
count of design patterns applied before the first line of business logic is
written.

These are DDD-adjacent choices. Each has its own justification, and none of
them is entailed by DDD. Wanting to decouple an API from the domain is a
good reason to add a DTO. "This is what DDD requires" is not, because it
does not.

## Strategic Design Is The Core

The building blocks are not the point, and this is not the repo's opinion.
Evans said so himself, ten years after the book, about the book:

> "things like the entities and value objects [..] [People] come away

How to install

The exact contents, by fingerprint
mdr add athola/claude-night-market/architecture-paradigm-domain-driven@sha256:a073e561d11cbf6d

The line at the top of this page pins the label git:20260921.ad5ceb4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
