Can I use this with existing TypeScript projects?

Yes, it includes a configuration checklist and refactoring patterns specifically designed to help transition existing projects to stricter, more modern TypeScript standards.

Why does this skill discourage the use of barrel files?

To optimize build performance. Avoiding internal barrel files can lead to significantly faster build times (up to 75%) by reducing module graph complexity.

Does it support Zod or other validation libraries?

Absolutely. The skill provides dedicated workflows for both manual type guards and schema-based validation using libraries like Zod for complex external API data.

How does this skill improve TypeScript type safety?

It enforces strict compiler settings, utilizes discriminated unions for state management, and implements runtime validation to catch errors that static analysis might miss.
