How does this skill help with existing codebases?

It provides standardized patterns to systematically replace 'any' types with type guards and 'unknown' references, modernizing the code for better compile-time safety.

Does it support the latest TypeScript features?

Yes, it includes guidance for modern features in TS 5.2 through 5.7, including 'using' for resource management and automatic inferred type predicates.

What are Branded types and why use them?

Branded types allow you to distinguish between identical primitive types (like UserID vs ProductID) at the type level, preventing accidental logic errors and enhancing security.

Why use Zod with this skill?

This skill integrates Zod to bridge the gap between compile-time types and runtime data, ensuring that external API inputs and outputs strictly match your internal definitions.

Does it improve error handling?

Yes, it prioritizes the Result pattern over throwing exceptions, which forces explicit handling of all possible success and failure states in your application logic.

개발자 도구

Implements strict type-safe patterns and modern TypeScript 5.5+ features to eliminate runtime errors and ensure data integrity.

소개

This skill equips Claude with specialized knowledge to write high-quality TypeScript code using strict configurations, modern features like resource management, and runtime validation via Zod. It focuses on replacing unsafe 'any' types with precise type guards and implementing robust error handling through Result patterns and discriminated unions. By leveraging this skill, developers can automate the modernization of their codebases while ensuring that domain logic is protected by branded types and exhaustive pattern matching.
