Write Domain-Driven Design code in FastAPI / Python — bounded contexts as packages with four layers, aggregates as plain classes with behavior, value objects as frozen dataclasses, application services, repository ports with async SQLAlchemy adapters and Alembic migrations, domain events, anti-corruption layers, and the REST interface with Pydantic schemas. Use when implementing or refactoring a FastAPI service around business rules, structuring a new bounded context in Python, or pulling…
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
# DDD in FastAPI Write the actual code for a Domain-Driven Design model in **FastAPI / Python**. The core rules below say *what* the building blocks are and when to reach for each; the references say *how to express them idiomatically* in FastAPI, and the assets and scripts write the parts that should come out the same every time. This is an **opinionated** house style: for every decision it names one convention and says what that convention buys, rather than listing options. It is one coherent way to do this, not the only correct one; where a choice is genuinely open, the reference says so. Python leaves more to taste than Java does, and the house style respects that: it fixes the decisions that make every bounded context look alike — where a file goes, what it is called, which layer may import which — and leaves the rest to the code in front of it. Examples use the **QuickBite** food-delivery domain — an `Order` in the `ordering` bounded context, a `Customer` in `customers`. …

How to install
mdr add salimramirez/agent-skills/ddd-fastapi@sha256:c8c63521547f3ad9The line at the top of this page pins the label v1.0.0, 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.
