Use when choosing a type annotation, deciding what shape a record takes as it crosses a boundary, or asking whether a comment belongs here. Owns the 3.13 house interpreter floor for a new deployable project and a distributed package's floor being its consumers', `X | None` over `Optional`, the ban on `from __future__ import annotations`, immutable collection types, when a type error may be silenced inline, the rule that a fixed-shape record is a declared type rather than a bare `dict` or…
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
# Python Style Project-wide rules that are stricter than CPython's defaults and hold **whatever the architecture is** — a hexagonal app, a flat-layered worker, or a standalone script. Two subjects: what the types look like, and where a comment is warranted. ## When to use vs. neighbours - Writing or changing any annotation, or any comment → this skill. - Any log call, event name or logging configuration → `python-logging`. - One class per module, `__all__`, the `__init__.py` re-export contract, import forms → `python-packaging`. - Deriving a concrete class or module name → `naming`; deriving a concrete artifact *path* in a hexagonal project → `hex-conventions`, in the `pyhouse-hex` plugin. - The exception classes themselves → `exception-catalog`. - Where a module lives and what may import it → `hex-architecture` (in the `pyhouse-hex` plugin) or `flat-layered` (in `pyhouse-flat`), whichever style the project uses. - The shape of a specific artifact → its own skill. This skill is consulted **alongside** them. ## Typing ### `X | None`, not `Optional[X]` ```python # yes name: str | None = None def find(id: UUID) -> Foo | None: ... # no from typing import Optional …

How to install
mdr add wntic/pyhouse/python-style@sha256:b452e460849c7c4aThe line at the top of this page pins the label git:20261011.a18d098, 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.
