ddd-fastapi skillA

ddd-fastapi is agent-read markdown (skill) from salimramirez/agent-skills: 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 busine.

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

# 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`.
