Use when laying out a Python service packaged with pyproject.toml (FastAPI or another web framework), or adding a feature, endpoint, use case, aggregate or repository to one — which package a module belongs in, which package may import which, and how an endpoint reaches a use case. Not for configuration, dependency or tooling changes.

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

# Clean Architecture — Python

The layer rules are those of `architecture-patterns`. This skill maps them onto Python packages.

## One package per layer

| Package | Holds | May import |
|---|---|---|
| `<context>.domain` | aggregates, value objects, domain events | the standard library only |
| `<context>.application` | use cases and the `Protocol`s they call | `<context>.domain` |
| `<context>.infrastructure` | implementations of those `Protocol`s (SQLAlchemy, HTTP clients, files) | `<context>.application`, `<context>.domain` |
| `<context>.api` | routes, the app factory, the wiring of every class | all three |

- Lay out `src/<context>/` with one sub-package per layer, in a single `pyproject.toml`. A new feature goes into the existing layer packages, never into a new top-level package.
- FastAPI, Pydantic, SQLAlchemy and HTTP clients are imported only in `infrastructure` and `api`. Domain and application use `dataclasses` and `typing`.
- ORM models and their mapping live in `infrastructure`; never make a domain class an ORM or Pydantic model.
- Tests live in the two test packages `clean-architecture-testing` defines, never inside `src/`.

How to install

The exact contents, by fingerprint
mdr add sebastiendegodez/skraft-plugin/clean-architecture-python@sha256:e4afaca524028595

The line at the top of this page pins the label git:20261009.6009e76, 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.
