How does this help with dictionary validation?

It promotes the use of TypedDict over generic dictionaries, enabling compile-time key checking, value type validation, and better IDE autocomplete.

Can it help resolve complex structural subtyping issues?

Absolutely. It provides detailed patterns for using Protocols to implement structural subtyping, allowing for flexible yet type-safe interfaces without explicit inheritance.

Does it support the latest Python 3.12 features?

Yes, it fully supports Python 3.12+ syntax, including the new simplified generic syntax and PEP 695 type parameter lists.

Why does this skill discourage using 'type: ignore'?

Using 'type: ignore' masks potential bugs and creates technical debt; this skill provides the correct structural or generic solution for every error instead.

Python Type Safety Patterns

API開発

Implements robust Python type annotations and structural subtyping to eliminate type errors without using suppressions like type: ignore.

概要

This skill provides a comprehensive framework for implementing strong type safety in Python backend applications using modern 3.10+ and 3.12+ syntax. It guides developers through complex typing scenarios—including structural subtyping with Protocols, generic repository patterns, and advanced type narrowing with TypeGuards—all while enforcing a strict 'zero type-ignore' policy. By providing standardized patterns for resolving mypy and pyright errors, it ensures codebase maintainability, enhances IDE autocomplete, and prevents runtime bugs through rigorous static analysis.
