Use when setting up a new Pragmatic.Design project, splitting it into libraries, modules and databases, or weighing a monolith against services (boundary libraries and host, sub-boundaries, multi-tenancy, what to enable).
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
# Pragmatic Architecture **Covers:** Structure a Pragmatic.Design project before writing code: boundary libraries and host, modules and sub-boundaries, databases, monolith vs distributed, multi-tenancy, what to enable. This skill is the structuring guide: **how to divide** a line-of-business app into libraries and modules, **what to enable**, and **when**. For attributes and usage patterns, proceed to the `pragmatic-use-*` skills. ## The standard structure A Pragmatic app has **one or more boundary libraries** (the domain) plus **one host** (the executable process): ``` MyApp/ ├── MyApp.slnx ├── NuGet.config ├── src/ │ ├── MyApp.Sales/ # boundary library: Sales domain │ │ ├── SalesBoundary.cs # [Boundary] │ │ ├── SalesModule.cs # [Module] │ │ ├── Orders/ # sub-boundary: a group of operations │ │ │ ├── Order.cs # entity, at the root of the group that writes it │ │ │ ├── OrderLine.cs # a child nothing writes on its own lives beside it │ │ │ ├── Mutations/ Actions/ Queries/ │ │ │ ├── Endpoints/ Dtos/ Validators/ Errors/ …

How to install
mdr add pragmatic-design/pragmatic.design/pragmatic-architecture@sha256:d87ebb736cf07783The line at the top of this page pins the label git:20261004.0320b67, 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.
