wshobson/python-type-safety

Pythonの型安全性:型ヒント、ジェネリクス、プロトコル、厳格な型チェック。型アノテーションの追加、ジェネリッククラスの実装、構造的インターフェースの定義、mypy/pyrightの設定に使用します。

python-type-safety とは?

このスキルは、Pythonプロジェクトにおける型安全性を確保するために設計されています。型ヒント、ジェネリクス、プロトコル(構造的サブタイピング)を活用し、mypyやpyrightといった型チェッカーの厳格な設定を通じて、コードの品質と可読性を向上させます。型アノテーションの追加やジェネリッククラスの実装、インターフェースの定義といった一般的なタスクを効率化し、開発者が安全で保守しやすいコードを書くためのベストプラクティスを提供します。主にClaude Code、Cursor、CodexなどのAIエージェント向けに最適化されており、Pythonの型システムを最大限に活用したい開発者にとって有用です。SKILL.mdに基づき、実行可能なコマンドや設定例、型チェックのワークフローが含まれています。

python-type-safety は何をしますか?

Pythonの型安全性:型ヒント、ジェネリクス、プロトコル、厳格な型チェック。型アノテーションの追加、ジェネリッククラスの実装、構造的インターフェースの定義、mypy/pyrightの設定に使用します。

概要

このスキルは、Pythonプロジェクトで型安全性を強化するためのものです。型ヒント(int, str, Optional, Unionなど)、ジェネリクス(TypeVar, Generic)、プロトコル(Protocol)を使用した構造的サブタイピング、そしてmypyやpyrightによる厳格な型チェック設定をサポートします。

使用例

型アノテーションの追加

def greet(name: str) -> str:
    return f"Hello, {name}"

ジェネリッククラスの実装

from typing import TypeVar, Generic

T = TypeVar('T')

class Stack(Generic[T]):
    def __init__(self) -> None:
        self._items: list[T] = []

    def push(self, item: T) -> None:
        self._items.append(item)

    def pop(self) -> T:
        return self._items.pop()

プロトコルの定義

from typing import Protocol

class Drawable(Protocol):
    def draw(self) -> None: ...

def render(obj: Drawable) -> None:
    obj.draw()

mypy/pyrightの設定

mypy.ini:

[mypy]
strict = True
check_untyped_defs = True
disallow_any_unimported = True
ignore_missing_imports = False

pyproject.toml:

[tool.pyright]
strict = [
    "src/**/*.py",
]
exclude = ["tests/**"]
