How does it handle unknown data from APIs?

The skill promotes using the 'unknown' type in TypeScript or 'object' in Python, combined with custom type guard functions to validate data structure at runtime.

Can I use this for refactoring existing projects?

Yes, it is designed to help elevate the 'Type Safety Level' of existing codebases from basic type annotations to advanced, 100% coverage patterns.

Why does this skill ban the use of 'any'?

The 'any' type bypasses the compiler's type checking, which hides potential bugs and makes code harder to maintain. This skill enforces safer alternatives like 'unknown' with type guards.

What tools does this skill recommend for type checking?

It provides configurations for the TypeScript compiler (tsconfig.json) and recommends using mypy or pyright for Python projects.

Does this support both TypeScript and Python?

Yes, it provides specific rules and patterns for both TypeScript (interfaces, utility types, strict mode) and Python (type hints, TypedDict, Protocol).

Comprehensive Type Safety

開発者ツール

Enforces strict type safety principles in TypeScript and Python by eliminating the use of any/Any types and implementing robust type guards.

概要

This skill enhances Claude's ability to write high-quality, maintainable code by adhering to strict type-safety standards across multiple programming languages. It provides clear guidelines for TypeScript and Python projects, including the mandatory use of strict mode, comprehensive type hints, and sophisticated type guards. By preventing the use of 'any' or 'Any' types, it reduces runtime errors and improves code readability, making it indispensable for developers focused on building production-grade, bug-free applications that are easy to refactor and scale.
